    [0001] The present invention relates to an electrical connector with an internal housing that is adapted to receive at least one contact assembly, an external housing and a locking arrangement, in which the internal housing is adapted to be inserted into the external housing in direct contact during assembly of the connector and where the relative position of an internal part to the external housing is maintained by the locking arrangement in a final assembly state of the connector.
    [0002] The electrical connectors of the type mentioned above are known from the prior art. In addition, during the assembly of known electrical connectors, the internal housing may be insufficiently inserted into the external housing. An incompletely assembled connector may not operate correctly. Thus, the invention aims to provide an electrical connector, the correct assembly of which can be controlled.
    [0003] The objective is obtained in that the connector has an indicator sleeve that is adapted to be inserted in the external housing against the direction of contact during the assembly of the connector and in which, in an incomplete assembly state, in which the internal housing it is arranged at a distance from its final mounting position in the outer housing, the locking arrangement forms an interrupting surface for the indicator sleeve, blocking a transfer of the indicator sleeve in its final mounting position.
    [0004] An operator or machine, which inserts the indicator sleeve into the external housing, can detect that the indicator sleeve cannot be transferred in its final assembly position. This indicates that the previous assembly steps may have been carried out in error.
    [0005] The solutions according to the invention can be combined as desired and further improved by the following modalities which are in each case advantageous.
    [0006] The indicator sleeve can basically comprise a concave cylindrical shape that extends along the contact direction when mounted in the outer housing. A counter-connector, which can be crossed with the electrical connector, can at least extend widely through the indicator sleeve. in the crossed state.
    [0007] According to a first possible modality, the connector can have a front seal that is adapted to seal the external housing and a housing of the crossed counter-connector. The front seal can be retained in a seal position in the outer housing by the indicator sleeve at least in the final assembly state. Holding the front seal in the seal position improves the seal performance of the connector during operation, as mechanical disturbances such as vibrations cannot work in the position of the front seal and may therefore not influence its seal performance. The improved sealing performance makes the electrical connector suitable for use in, for example, automotive or aeronautical applications.
    [0008] The indicator sleeve can be provided with at least one locking member to lock the indicator sleeve in the external housing and in its final mounting position. An indicator sleeve that is locked in the outer housing in the final assembly state cannot be inadvertently removed while retaining the front seal in the seal position, ensuring that the front seal remains in its seal position.
    [0009] In another advantageous embodiment, the indicator sleeve can be provided with another locking member next to the locking member mentioned above. The two locking members can be arranged one after the other in the contact direction and can consecutively engage with at least one locking member of the external housing. When assembling the connector, first a locking member can be mounted in the external housing and can, for example, fit with at least one counter member. The other locking member can lock the indicator sleeve in the remote outer housing from its final mounting position. This ensures that the inner housing can be inserted into the outer housing up to its final assembly position without being carried out by the pre-assembled indicator sleeve. In addition, at least the indicator sleeve and the outer housing can form a first pre-assembly unit. The indicator sleeve can, in a pre-assembled state, be remote from its final mounting position, still being affixed to the external housing by another locking member. To attach the indicator sleeve to the remote outer housing from its final mounting position, it can be locked in the outer housing via the other locking member.
    [00010] When another insertion of the indicator sleeve to the external housing of the pre-assembled position and in its final assembly position, the locking member can still engage with at least one counter-locking member or with another locking member. fitting event may indicate that the indicator sleeve is inserted into the housing external to the first pre-assembled state. Just close to the first and yet a second fitting event occurs, the indicator sleeve has reached its final mounting position and a correct connector assembly is In particular, it is indicated by the second fitting event that the inner housing is not only inserted completely into the outer housing, but has reached its final mounting position in the outer housing.
    [00011] In the state of incomplete assembly, in which the internal housing is arranged at a distance from its final assembly position, the locking arrangement can at least be extensively elastically deflected across the direction of contact and from a coupling position , in which the position of the internal housing is locked in the final assembly state, in a locked position. In the locked position, the locking arrangement can at least partially be arranged in the form of the indicator sleeve when it is inserted into the outer housing. The locking arrangement can be an integral part of the internal and / or external housing or it can be a separate part that is locked or, otherwise, fixed to the internal and / or external housing in the final assembly state.
    [00012] For example, the locking arrangement may comprise a locking lever, the free end of which can be elastically deflected in the state of incomplete assembly. The free end may comprise a front or stationary surface pointing in the direction of contact, with which the indicator sleeve may collide in the state of incomplete assembly. In addition, the free end of the locking lever can comprise a safety protrusion, which can positively engage with a locking recess of the internal housing in the final assembly state. Due to the positive fit, the safety protrusion and the locking recess, the position of the internal housing is maintained in its final assembly state and relative to the external housing.
    [00013] In the final assembly state, a locking position of the locking arrangement can be secured by the indicator sleeve. Thus, the indicator sleeve can overlap the locking arrangement transverse to the contact direction and block an elastic deformation of a section of the arrangement. locking mechanism, for example, from the free end of the locking lever.
    [00014] If the electrical connector provides the electromagnetic protection properties, it can have a protection member that extends in the direction of contact and between an internal part and the external housing in the final assembly state. At least the inner housing and the protective member can be combined to form a second pre-assembly unit in a second pre-assembled state. In addition, the second pre-assembly unit can be handled as a single piece. The protection member can comprise elements to guide during assembly. The internal housing may also have the means to guide the protection member. For example, the protection member can be pushed or moved in the inner housing in the direction of contact, this movement being guided by the means to guide in cooperation with the guiding elements.
    [00015] For example, the guard member may have at least one guide bar that extends in the direction of contact, and the internal housing at least one guide slot for at least one guide bar. At least one guide groove can extend in the direction of contact and from a limit wall for the guide bar towards an insertion end. Thus, the protection member can be pushed into the inner housing against the contact direction. In such an arrangement, the guide groove may extend from the boundary wall in the direction of contact.
    [00016] The guide bar can be arranged on a free end of a guide tongue of at least one of the guards. The guide tongue can be tilted towards the opposite side plate and extend along the contact direction. The guide tongue can be adapted to be at least widely received by the guide groove by sliding the guard along the contact direction and in its final mounting position. In the final assembly state, the guide tongue can be at least widely received in the guide groove and can be supported against the boundary wall. In addition, the opposite side plate can be formed with a guide tongue, which can be tilted towards the first side plate and which can be received by a guide groove on the opposite side wall of the internal housing. The protection member can comprise other means to guide, for example, a guide projection that can be scaled on the protection member.
    [00017] The second pre-assembly unit can in another advantageous mode be secured by the locking arrangement in a final assembly position in the final assembly state. Not only the internal housing, but also the protection member is then kept in its final mounting position.
    [00018] The protective member can at least be widely arranged on the side surfaces or side walls of the inner housing, the side walls extending parallel to the direction of contact. For example, the guard member may comprise two guards that can be placed on the opposite side walls of the inner housing transverse to the contact direction. The guards can at least largely comprise a basically U-shaped cross-section with two side plates, which can extend at least over half of a side wall of the inner housing which runs parallel to the respective side wall or side surface. Thus, all the side walls of the inner housing can essentially be covered by the protection member, which at least can have a largely concave cylindrical shape.
    [00019] Forming the protection member as at least two protections provides an easy installation of the protection member in the internal housing. Each of the guards can be moved towards the inner housing perpendicular to the contact direction on the opposite sides. First, a guard can be moved towards the inner housing until it is in contact with a side surface of the inner housing. Then, it can be changed along the contact direction until it is in contact with an interrupting surface, for example, the limit wall of the guide groove or with another interrupting surface. This procedure is then repeated with the other protection. The two guards can be electrically interconnected at least by the bent connection.
    [00020] To obtain good protection properties, it is desirable to prevent any gaps in the connection between a cable protection and the protection member. Thus, the protective member at its end facing the direction of contact can be characterized with a neck, which can be adapted to surround the cable in the state of final assembly. The bent connection can be established by the two bent tubes which can be arranged in a concentric arrangement around the cable. A neck of the protection member, which can be adapted to the size of the cable, can be arranged between the two bent tubes. By the bent connection, the protection member can be not only mechanically, but also electrically connected to the cable. For example, a cable protective plate may be in electrical contact with at least one of the two bent tubes, so that a bend tube establishes an electrical connection between the protective plate and the protective member. In an advantageous embodiment, not only the neck of the protective member, but also a part of the protective plate can be arranged between the two bent tubes, providing a direct electrical connection between the plate and the protective member.
    [00021] As the guard member can be, for example, by a locking tab not only electrically, but also mechanically connected to a guard member of the counter-connector, it may be favorable to arrange the boundary wall at one end of the groove- guide, which points to the contact direction, resulting in a boundary wall that is turned against the contact direction. With such an arrangement, the protection member can be slid over the internal housing in the direction of contact until the guide bar touches the limit wall. Another involuntary movement in the direction of contact, for example, by a non-crossed procedure of the connector and the counter-connector, is blocked by the limit wall.
    [00022] The protection member can have at least one locking member which is engaged with a locking structure of the internal housing in the pre-assembled state. In particular, the engagement between the locking member and the locking structure can prohibit the protection member from sliding from the inner housing at least against the contact direction while mounting the electrical connector.
    [00023] The electrical connector can have a first contact position guarantee member to maintain at least one contact assembly in its final assembly position. The first guarantee member of the contact position can maintain the contact elements of at least one contact assembly against involuntary movements in and / or against the contact direction.
    [00024] Alternatively or additionally, the electrical connector can be provided with at least a second guarantee member of the contact position to maintain the internal housing in its final assembly position. The second contact position guarantee member can be applied to the outer housing after the inner housing has reached its final mounting position. It can in particular prevent the inner housing from being moved with respect to the outer housing and in the direction of contact during a non-cross-contact and counter-contact procedure.
    [00025] It may be necessary to seal not only the connection between the connector and the counter-connector, but also the connection between the connector and the cable. Thus, the electrical connector may comprise a cable seal that can surround the cable to prevent moisture from entering along an external surface of the cable. In the final assembly state, the cable seal may be arranged in a rear end cap of the connector and may be in sealing contact with the inside of this rear end cap.
    [00026] The invention will be described below and in an exemplary manner using advantageous modalities and with reference to the drawings. The described configurations, however, in which the individual functions as described above can be provided independently of one another and can be omitted as shown in the drawings: Figure 1 is an enlarged schematic view of an exemplary embodiment of the invention; Figure 2 is a schematic perspective view of an indicator sleeve; Figure 3 shows an exemplary embodiment of a contact assembly; Figure 4 is a schematic perspective view of an embodiment of an electrical connector internal housing; Figure 5 is a schematic perspective view of a second partially assembled pre-assembly unit; Figure 6 shows an enlarged detail of Figure 5; Figure 7 shows the second fully assembled pre-assembly unit connected to a cable in a schematic perspective view; Figure 8 shows an enlarged detail of Figure 7; Figure 9 shows a section of an exemplary embodiment of a locking arrangement according to the invention in a cross-sectional view; Figure 10 is another cross-sectional view of the connector in a final assembly state; Figure 11 shows another cross-sectional view of a first connector pre-assembly unit.
    [00027] First, an electrical connector 1 according to the invention will be described with reference to Figure 1, which shows an enlarged view of an embodiment of the invention.
    [00028] In some embodiments, the electrical connector 1 may comprise an inner housing 2 and an outer housing 3. The outer housing 3 can be adapted to receive at least inner housing 2 in a contact direction C. In contact direction C , connector 1 can be connected with a counter-connector. For example, the outer housing 2 can basically comprise a concave cylindrical shape. The outer housing 3 can form a duct or tunnel 4, which extends through the housing 3 in the direction of contact C. To the duct or tunnel 4, the inner housing 2 can be inserted in the direction of contact C and in the final mounting position. Against the direction of contact C the counter-connector can at least be widely inserted into the duct 4.
    [00029] The internal housing 2 can be adapted to receive at least one contact assembly 5. The contact assembly 5 may in some embodiments comprise at least one contact element 6, which can be attached to the internal housing 2. For example, the contact element 6 can be inserted into the inner housing 2 in the direction of contact C and locked into the inner housing 2. In addition, the contact element 6 can be conductively and mechanically connected to a wire 7 of a cable 8. If the cable 8 comprises more than one wire 7 or if more than one cable 8 must be connected to the inner housing 2, the inner housing 2 can be adapted to receive more than one contact element 6. For example, the contact assembly 5 can comprise four contact elements 6 and the inner housing 2 can be adapted to receive at least these four contact elements 6.
    [00030] The connector 1 may in some embodiments be equipped with at least one first guarantee member of the contact position 9, which can maintain the relative position of at least one contact element 6 in the internal housing 2. The first guarantee member of the contact position 9 can comprise at least one protrusion of the latch 9 ', which can be engaged with the contact element 6 in a final mounting state of the connector 1, blocking the movements of the contact element 6 at least against the contact direction C. The first guarantee member of the contact position 9 can also comprise a fixing plate 9 '', which protrudes the engagement 9 'from an involuntary removal of the internal housing 2.
    [00031] In some embodiments, electrical connector 1 may be a protected electrical connector 1. For example, connector 1 may comprise a protective member 10 that can at least be widely arranged on the side walls 11 of the inner housing 2, the walls side 11 that extend parallel to the contact direction C. For example, the guard member 10 can comprise two guards 10 ', 10' 'that can be placed on the opposite side walls 11 of the inner housing 2 across the contact direction C. The guards 10 ', 10' 'can at least largely comprise a basically U-shaped cross-section with two side plates 12, 12', which can extend at least over half of a side wall 11 of the inner housing 2. Thus, all the side walls 11 of the inner housing 2 can essentially be covered by the protection member 10.
    [00032] When mounting the connector 1, it may be advantageous to first fix the contact element 6 or several contact elements 6 to the front ends of the wires 7, to insert and maintain the contact element 6 in the internal housing 2 and then arrange the protective member 10 on the outside of the inner housing 2. At least the inner housing 2 and the protective member 10 can form a second pre-assembly unit, which can be handled as a piece.
    [00033] If the cable 8 is of a protected type, it may be favorable to electrically connect a cable protection 8 to the protection member 10. To achieve good protection properties, it is desirable to prevent any gaps in the connection between the cable protection 8 and the protective member 10. Thus, the protective member 10 can at its end facing against the direction of contact C be characterized with a neck 13, which can be adapted to surround the cable 8 in the final assembly state. The protection member 10 can be attached to the cable by a bent connection 14 which also provides an electrical connection between the cable protection 8 and the protection member 10.
    [00034] In some environments, for example, in an automotive or aeronautical environment, it may be necessary to seal connector 1 against moisture. Thus, the electrical connector 1 may in some embodiments comprise a cable seal 15, which can surround the cable 8 to prevent moisture from entering along an external surface of the cable 8. In the final assembly state, the cable seal 15 , can be arranged in a rear end cap 16 and can be in sealing contact with the inside of the rear end cap 16.
    [00035] In addition, it may be necessary to seal a connection between connector 1 and the counter-connector. Thus, connector 1 may comprise a front seal 17.The front seal 17 may have an essentially cylindrical concave shape, so that it can surround the duct 4. Transverse to the direction of contact C, the front seal can be formed in a complementary way to the internal part of the external housing 3. In Figure 1, the front seal 17 basically has a rectangular cross-section.
    [00036] When inserted into the outer housing 3 against the direction of contact 4, the front seal 17 can be retained in a seal position D in the outer housing by an indicator sleeve 18 at least in the final assembly state. be adapted to be at least widely inserted in duct 4. At least the outer housing 3 and the indicator sleeve 18 can be combined to form a first pre-assembly unit, where the indicator sleeve 18 can be mounted and, for example, locked in the remote outer housing from its final mounting position. In addition, the first pre-assembly unit can be manipulated as a single part.
    [00037] In the final assembly position of the internal housing 2 in the external housing 3, the indicator sleeve 18 can be transferred from its pre-assembly position to its final assembly position. If, however, the inner housing 2 is arranged in the outer housing 3 at a distance from its final mounting position, a transfer of the indicator sleeve 18 to its final mounting position can be blocked.
    [00038] To keep the inner housing 2 in its final mounting position, a locking arrangement can be provided. The locking arrangement can at least be extensively deflected when the inner housing 2 is arranged in the outer housing 2 remote from its final mounting position. Thus, at least one section of the locking arrangement can form an interrupting surface, which blocks the transfer of the indicator sleeve 18 in its final mounting position.
    [00039] In order to maintain an involuntary movement of the internal housing 2 relative to the external housing 3 at least in the direction of contact C, the connector 1 can be provided with a second guarantee member of the contact position 19. The second guarantee member of contact position 19 can be fixed to the external housing and can project to duct 4 in the final assembly state.
    [00040] Figure 2 shows the indicator sleeve 18 in an enlarged perspective view.
    [00041] Indicator sleeve 18 can basically comprise a concave cylindrical shape and extend along the direction of contact C. When mounted in outer housing 3, duct 4 can extend through indicator sleeve 18 along the direction of contact C .
    [00042] In some embodiments, at least one locking member 20 can be provided on the indicator sleeve 18. The locking member 20 can project from the indicator sleeve 18 perpendicular to the direction of contact C in the final assembly state. For example, at least one locking member 20 can be formed with a pointed surface 21, which can at least be partially directed against the direction of contact C. Opposite the pointed surface 21, the locking member 20 can be formed with a surface locking element 22 which can extend perpendicular to the contact direction C.
    [00043] In the direction of contact C behind the locking member 20, the indicator sleeve 18 may comprise another locking member 23, which can be in a way comparable to the locking member 20. The other locking member 23 can be engaged with a locking member of the outer housing 3 in the final mounting state of the electrical connector 1. Locking member 20 can be engaged with a locking member of the outer housing at least in the first pre-assembled state .
    [00044] Locking member 20, 23 can be provided on at least one, or perhaps at least two, inner side walls of indicator sleeve 18. In particular, locking member 20, 23 can be arranged on opposite internal side walls of the indicator sleeve 18, where at least one locking member 20 and at least another locking member 23 can be arranged on each of the opposite side walls.
    [00045] In some embodiments, the first locking member 20 engages with the locking member of the external housing 3 when mounting the electrical connector 1. Consecutively, the other locking member 23 can engage the coupling with the respective counter member locking of the outer housing 3. Thus, an operator who assembles the electrical connector 1 may be able to distinguish the state of incomplete mounting from the state of final mounting by the number of locking or fitting events when inserting indicator sleeve 18 to the outer housing 3 Only one fitting or locking event indicates an incomplete mounting state, more than one and particularly two fitting or locking events indicate that the inner housing 2 is arranged in its final mounting position.
    [00046] In some embodiments, the indicator sleeve 18 can be formed with a counter surface 24, which is directed against the direction of contact C. The counter surface 24 can interact with the interruption surface of the locking arrangement when the internal housing 2 is arranged at a distance from its finally assembled position.
    [00047] When the interrupting counter surface 24 touches the interrupting surface of the locking arrangement, another insertion of the indicator sleeve 18 into the outer housing 3 can be blocked. Blocking the movement, at least the other locking member 23 is prevented from engaging against the locking member of the outer housing 3.
    [00048] The counter surface 24 can be arranged behind a front surface 25 of the indicator sleeve 18. For example, the counter surface 24 can be arranged in a recess 26, which is arranged on one of the side walls. of the indicator sleeve 18 and that opens against the direction of contact C. The indicator sleeve 18 can be formed with a second against interrupting surface 24 'that can be arranged on a floor of another recess 26'.The recesses 26, 26' can be arranged on the opposite side walls of the indicator sleeve 18.
    [00049] Locking members 20 and other locking members 23 can be provided on different side walls than recesses 26, 26 '. The side walls, on which the recesses 26, 26 'are arranged can travel essentially perpendicular to the side walls where the locking members 20 and the other locking members 23 can be provided.
    [00050] In addition, the indicator sleeve 18 can be characterized with a safety surface of the locking arrangement 27, 27 'behind each of the recesses 26, 26' in the direction of contact C. In the final assembly state, at least a safety surface 27, 27 'can be arranged in front of a section of the locking arrangement, the section being elastically offset perpendicular to the direction of contact C. At least one safety surface, 27, 27' can overlap the arrangement section blocking crosswise to the contact direction and blocking deviation from this section. Thus, the locking arrangement is prevented from unintentionally unlocking between the inner housing 2 and the outer housing 3.
    [00051] In some embodiments, the indicator sleeve 18 may comprise at least one retaining surface 28 that can point against the direction of contact C. The retaining surface 28 may be arranged behind the counter surface 24 or more behind the surface , 27, 27 'essentially along the rear surface 29 of the indicator sleeve 18. The retaining surface 28 can extend completely or at least partially around the duct 4. If more than one retaining surface 28 is provided, the retaining surfaces 28 may be arranged symmetrically around the duct 4. At least the other locking member 23 may be disposed before the retaining surface in the direction of contact C. The retaining surface 28 disposed close to the rear surface 29 of the sleeve Indicator 18 can be formed to abut internal housing 2 in the final assembly state.
    [00052] Figure 3 is an enlarged view of the contact assembly 5. The rear termination cover 16 can open in the direction of contact C and the cable seal 15. The cable 8 can be carried through the termination cover 16 and a front seal 17 along contact direction C. In some embodiments, the termination cap 16 may have a receiving volume 30 that opens in contact direction C for cable sealing 15. The receiving volume 30 can be formed in a complementary manner to the cable seal 15, so that the sealing ribs 31 that abut seal against the inner side walls of the termination cover 16. To maintain the position of the cable seal 15 in the condition of the termination cover 15, at least the sections of the termination cover cable seal 15 can positively engage with termination cap 16. For example, termination cap 16 can be provided with at least one retaining pin 32, which can be placed in a retention opening 33 of the cable seal 15 when the cable seal 15 it is inserted in the receiving volume 30. A retaining pin 32 can be arranged in each corner of the termination cover 16, which can have an essentially rectangular cross-section perpendicular to the direction of contact C. The respective retaining openings 33 can be provided in the seal of the cable 15. Each retaining opening 33 can surround by sealing the retaining pin 32 at least partially.
    [00053] Figure 4 shows an enlarged view of the inner housing 2. A cross end 34 of the inner housing 2 facing in the direction of contact C and may, in the final state of electrical connector 1, form part of a contact surface of the electrical connector 1. In some embodiments, the contact surface may comprise a guide groove in the form of a T 35 that can extend in the direction of contact C and which can be accompanied by two contact cylinders 36, 36 '. At an open end 37 of the guide groove 35, the open end 37 which tip transverse to contact direction C, a contact member 38 can be provided. Contact member 38 may have locking means for securing electrical connector 1 to the counter-connector. The cross end 34 can be integral with the plug surface of an electrical connector 1 male or female.
    [00054] The inner housing 2 can be formed with side surfaces or side walls 39, which extend along the direction of contact C. In some embodiments, at least one of the side surfaces 39 can be formed with at least one guide groove 40 that extends in the direction of contact 3 and ends in a boundary wall 41. The boundary wall 41 can essentially extend perpendicular to the direction of contact C and can serve as an interrupting surface for the protective member 10. For example, the limit wall 41 can face towards the direction of contact C, so that the guide slot 40 opens against the direction of contact C and ends in the direction of contact C on the limit wall 41. The open end of the guide slot 40 it can be formed as an insertion end K for a section of the protection member 10.
    [00055] Guide grooves 40 can be provided on opposite side surfaces 39. Alternatively or additionally, a guide groove 40 'can be provided on a side surface or side wall 39' of inner housing 2, side surfaces or side walls 39, 39 'extending at an angle and, for example, perpendicular to each other. Guide grooves 40, 40 'can start at a distance from one another in the direction of contact C. For example, guide groove 40 can start before guide groove 40': In addition, guide grooves 40, 40 'can have the same length in the direction of contact C. The insertion ends K, K 'of the guide grooves 40, 40' can point in the same direction, for example, against the direction of contact C.
    [00056] In some embodiments, the inner housing 2 can be formed with a locking structure 42 for the protection member 10. By means of the locking structure 42, the protection member 10 can be fixed along the direction of contact C in the inner housing 2. For example, the locking structure 42 can comprise at least one locking protrusion 43, which can project from one of the side surfaces 39. For example, the locking protrusion 43 can be arranged close to one of the grooves- guide 40, 40 'perpendicular to the contact direction C. If more than one locking protrusion 43 is provided, the locking protrusions 43 can accompany the guide groove 40, 40' across the contact direction C.
    [00057] In some embodiments, the inner housing 2 may comprise a part of the locking arrangement. For example, it can be formed with a locking recess 44, which can be arranged on one of the side surfaces 39, 39 'and in particular on the side surface 39, on which also the locking structure 42 for the protection member 10 can be provided. The locking recess 44 can open perpendicular to the direction of contact C and can be arranged between one of the boundary walls 41, 41 'and the crossed end 34.
    [00058] The side surfaces 39, 39 'can be joined in a rounded projection 45 that extends parallel to the contact direction C. From the projection 45 an interruption protrusion 36 for the protection member 10 can project perpendicularly from the projection 45 and in the contact direction C. An interrupt protrusion 46 for the protection member 10 can project from one of the side surfaces 39, 39 'or from the projection 45.
    [00059] Figure 5 shows the second pre-assembly unit 51 in a partially assembled state. Contact elements 6 of the contact assembly 5 can be connected to the inner housing 2 and held in the inner housing 2 by the first position guarantee member contact 9.
    [00060] The neck 13 of the protection 10 '' is against the cable 8, the side plate 12 of the protection 10 '' at least partially overlaps the lateral surface 39 'of the internal housing 2.
    [00061] To transfer the 10 '' guard in its final mounting position, it can be slid in the direction of contact C. A guide tongue 47 of the 10 'guard can be tilted in the direction of the opposite side plate 12' and extend along the contact direction C. A free end of the guide tongue 47 can be formed as a guide bar 47 ', which points in the direction of the inner housing 2 and extends parallel to the direction of contact C. The guide tongue 47 and at least its guide bar 47 'can be adapted to be received at least widely by the guide groove 40' by sliding the guard 10 '' through the direction of contact C and in its final mounting position. In the final assembly state, the guide tongue 47 can at least be widely received in the guide groove state 40 'through its insertion end K'. In addition, the opposite side plate 12 'can be formed with a guide tongue 47, which can be tilted towards the side plate 12 and which can be received by the guide groove 40' of the opposite side wall 39 '.
    [00062] Figure 6 is an enlarged view of Figure 5. Perpendicular to the direction of contact C a pair of recesses can extend through the guide tongue 47, of which only recess 48 is shown. The guide tongue 47 may not protrude from the guard 10 '' across the direction of contact C and parallel to the adjacent side surface 39 '. Guide tongue 47 and guard 10 '' can be transverse in the direction of contact C and parallel to the side surface 39 'of the inner housing 2 along a straight line.
    [00063] Two locking tabs 49, 50 can project from side plates 12, 12 'of guards 10', 10 '' across the direction of contact C and away from opposite side plates 12 ', 12. One locking tab 49, 50 can be arranged before the guide clamp 12 in the direction of contact C. The free ends of the locking tabs 49, 50 can point against the direction of contact C and can be elastically deflected towards the side plate 12.
    [00064] The locking tab 49 can be adapted to lock the protections 10 ', 10' 'in the final mounting state of the electrical connector 1. The locking tab 50, which can be arranged behind the locking tab 49 in the direction of contact C, can be adapted to lock with the counter-connector. In addition, the locking tab 50 can also be electrically connected to the protection member of the counter-connector.
    [00065] Figure 7 shows the second pre-assembly unit 51 in the second pre-assembled state P2. Both protections 10 ', 10' 'are slid into the inner housing 2. Protections 10', 10 '' can be a similar design and be arranged symmetrically to the mirror around the inner housing 2. At least the protection 10 'may comprise an interruption recess 52, which is placed in the interruption protrusion 46. A central plate 53, extending in the direction of contact C and which interconnects the side plates 12, 12 'is shown with two locking tabs 50 arranged next to each other in the direction of contact C. Thus, the second pre-assembly unit 51 can comprise two locking tabs 50 on each side, the sides extending parallel to the direction of contact C.
    [00066] From the central plate 53 a guide projection 54 can project towards the opposite protection 10 ''. The guide projection 54 can engage with the guide groove 40 of the inner housing 2 by sliding the guard 10 'into the inner housing 2 in the direction of contact C.
    [00067] In some embodiments, at least one of the guards 10 ', 10' 'may comprise at least one locking member which is engaged with the locking structure 42 of the internal housing 2 in the pre-assembled state. For example, guard 10 'may comprise a locking member in the form of a lock opening 55 for each lock protrusion 43 of the inner housing 2.
    [00068] The central plate 53 of at least the protection 10 'can be formed with a through hole 56, which can be aligned with the locking recess 44 of the internal housing 2 in the pre-assembled state. The locking recess 44 can be reached through the through hole 56 on the outside of the second pre-assembly unit. A locking tab 57 can extend in the direction of contact C towards its free end. The locking tab 57 can engage with the locking arrangement of the electrical connector 1 or it can be tilted to the locking recess 44, further improving the mechanical connection between the protection member 10 and the internal housing 2.
    [00069] A second pre-assembly unit 51 can be connected to the cable 8. For example, the protection member 10 can be connected to the cable 8 by the bent connection 14. The cable seal 15 and the rear end cap 16 can consecutively or together be pushed in the direction of contact C towards the fold connection 14 and overlap the central plate 53 in the direction of contact C.
    [00070] Figure 8 is an enlarged view of Figure 7. The locking protrusions 43 project into the locking openings 55 transversal to the direction of contact C and away from the inner housing 2. Before the locking openings 55 in the direction of contact C stop , cones 58 can be supplied, of which only half can project from the central plate 53 across the direction of contact C. The stop bases 59 of the stop cones 58 can face the contact direction C and away from the inner housing 2. The interrupter bases 59 can block another movement relative to the outer housing 3 in the direction of contact C, when the second pre-assembly unit 51 has reached its final mounting position in the outer housing 3.
    [00071] Figure 9 is a cross-sectional view of the electrical connector 1. The second pre-assembly unit 51 is arranged in the outer housing 3 in an incomplete assembly state I, in which the inner housing 2 is arranged before its position of final assembly inside the outer housing 3. A locking lever 60 of the locking arrangement L can be elastically deflected perpendicular to the direction of contact C and away from the inner housing 2. It can slide into the inner housing 2 or the protective member 10 while inserting the inner housing 2 to outer housing 3. Its front surface 61 can act as a stop surface 61 that can block the insertion of the indicator sleeve 18 to outer housing 3 in the shown locking position B.
    [00072] When another insertion of the inner housing 2 or the second pre-assembly unit 51 into the outer housing 3, the locking recess 44 can fall in line with a safety protrusion 62 of the locking lever 60, which can then be pushed to the locking recess 44 by an elastic force caused by the locking lever 60. The safety protrusion 62 can project from the locking lever 60 perpendicular to the direction of contact C towards the internal housing 2. If the electrical connector 1 is of the protected type , the security protrusion 62 can extend through the through hole 56 to the locking recess 44. The front seal 17 is shown arranged in its seal position D within the outer housing 3.
    [00073] Figure 10 is a perspective cross-sectional view of electrical connector 1 in the final mounting state F. The internal housing 2 has reached its final mounting position F2 in the external housing 3. If the connector 1 is of a protected type, the second pre-assembly unit 51 is shown arranged in its final assembly position F51. In addition, indicator sleeve 18 is positioned in its final assembly position F18.
    [00074] The safety protrusion 62 may in the final assembly state F shown be arranged in its engaging position E, in which it is at least largely arranged in the locking recess 44 and / or through hole 56. The locking lever 60 it may not be tilted or only slightly elastically inclined perpendicular to the direction of contact C away from the inner housing 2. By the positive fit between the safety protrusion 62 and the locking recess 44 the position of the inner housing 2 within the inner housing 3 is secure. The locking lever 60 can be an integral part of the outer housing 3 or it can be a separate part, which can be locked or attached to the outer housing 3. The locking arrangement L can at least comprise the locking lever 16 and at least at least one counter blocking element, for example, the locking recess 44 and / or the through hole 56.
    [00075] In the final assembly state F, the indicator sleeve 18 reached its final assembly position F18. The front surface 25 of the indicator sleeve 18 can abut against the front seal 17 and maintain the front seal 17 against movements outside its final assembly or sealing position D in the direction of contact C.
    [00076] The safety surface 27 can overlap the locking lever 60 on its safety protrusion 62, blocking the movements of the safety protrusion 62 outside its engaging position E and the positive engagement with the locking recess 44.
    [00077] Figure 11 shows a first pre-assembly unit 63 in a first pre-assembled state P1. Indicator sleeve 18 is locked in outer housing 3 by its other locking member 23, which is engaged with a first against member locking member 64. The other locking member 23 engages behind the first counter-locking member 64, so that an involuntary movement of the indicator sleeve 18 in the direction of contact C is being avoided. By inserting the indicator sleeve 18 into the outer housing 3 against the direction of contact C, the locking member 20 can be pushed over the first against locking member 64. In addition, the other locking member 23 can be pushed over a second against locking member 65 when transferring the indicator sleeve 18 from the pre-assembly position S shown to the final assembly state F.
