    field of invention
    [0001] The present invention relates to a connector system, comprising a plug connector and a retainer, both adapted for connection to the corresponding sockets, and an electrical connection between the plug connector and the socket can only be established if the connector system is correctly mounted. Invention history
    [0002] In many fields of application, it is important that secure couplings between connectors and their counterparts against connectors can be guaranteed. Especially in the case of automotive safety restraint systems, such as, for example, airbag systems in passenger vehicles, the plug connectors used to connect an airbag to the respective ignition base, i.e. a detonator socket, must be equipped with reliable security systems. Typically, for this purpose, plug connectors are equipped with connector position assurance (GPC) elements, which can be inserted in a locked position into the plug connector only if the plug connector is properly connected to the airbag detonator socket . In this position, the GPC element provides additional security for connecting the plug connector and detonator socket, and typically the GPC element is constructed so that an operator can visually detect whether the GPC element is inserted correctly, in its locked position. In this way, a correct and secure union between the connector and the counter connector can be guaranteed.
    [0003] An example of a plug connector equipped with GPC element is disclosed in EP 1 207 591 A2. It describes a plug connector that can be connected to a detonator socket of an airbag connector system. In the assembled condition, when the plug connector is inserted into the airbag detonator socket, the plug connector is secured inside the socket by means of flexible locking arms. During insertion of the plug connector into the socket, said arms bend inwards until the locking projections provided on the locking arms engage the corresponding locking recesses of the airbag detonator socket.
    [0004] A GPC element is provided to secure the contact of the plug connector with the airbag detonator socket. When the plug connector is inserted into the airbag detonator socket and the locking projections are fitted into the locking recesses, the GPC element can be inserted into a plug connector housing. The GPC element comprises locking arms which, upon insertion, move into the slots between the faces of the plug connector housing and the locking arms. Once these lock arms are inserted into the slots, the folding of the lock arms is locked, so the lock arms are fixed within the recesses and the connection between the plug connector and the airbag detonator socket is ensured. According to EP'591, only when the connectors are correctly connected can the GPC element be moved to the locked position, in which it will ensure the connection of the connectors. This can be visually detected by an operator, and thus it is possible to guarantee the correct connection of the connectors.
    [0005] Even if the solution, as proposed in EP'591, works satisfactorily for certain applications, the use of a GPC element is undesirable, for example, due to space limitations. An example of a plug for connecting to a detonator socket without a GPC element is disclosed in DE 202 16 337 U1. The plug connector disclosed there is an example of the so-called "scoop-proof" plug connector, which is equipped with a connecting tube around the electrical contacts of the plug connector. connecting the plug connector to a detonator socket, the contact terminals of the plug connector can only be correctly connected to the corresponding contact pins of the airbag detonator socket If the plug connector is not correctly inserted into the airbag detonator socket , the connecting tube abuts the airbag detonator socket, so that false connection between the contact terminals and the pins is prevented.
    [0006] In order for the plug connector to be mechanically connected to a detonator socket, the plug connector is equipped with locking arms secured to the connecting tube, so that when inserting the plug connector into the socket, the locking arms fold inward and upon full insertion of the plug connector into the airbag detonator socket, the locking projections provided on the locking arms engage the corresponding locking recesses of the airbag detonator socket.
    [0007] Another example of a plug connector to be connected to a detonator socket without a GPC element is disclosed in EP 2 23 0 731 A1. In this, similarly to the above example, a "scoop-proof" plug connector is described, said plug connector can be connected to the corresponding detonator socket by means of locking arms mounted on flexible parts provided in a tube of the plug connector connection. Due to the flexibility of the locking arms, at the time of insertion of the plug connector into the airbag detonator socket, the locking arms fold inwards, and at the time of full insertion of the plug connector, locking projections provided on the arms The locking tabs snap into the socket recesses to lock the plug connector into the airbag detonator socket.
    [0008] The locking arms of the EP'731 are also equipped with release elements that, when the plug connector is connected to the airbag detonator socket, can be actuated by an operator, ie, can be pressed inwards, to release the locking projections from the locking recesses. Therefore, the plug connector will be free to be removed from the socket. Although the last two plug connectors are equipped with reliable locking mechanisms and can be connected to detonator sockets without GPC elements, both plug connectors lack the ability to visually detect the connection of the plug connectors to the detonator sockets.
    [0009] Thus, it is an object of the present invention to improve the state of the art by providing a plug connector for a connector system with improved locking means, so that the correct connection of the plug connector to a corresponding detonator socket can be guaranteed, without the need for a GPC element. It is another object of the present invention to provide a plug connector for a connector system that facilitates assembling the plug connector with a socket. It is yet another object of the present invention to accomplish such tasks by providing an inexpensive product, which can preferably be produced from injection molded parts.
    [0010] These and other objectives that will become apparent upon reading the descriptions below are solved by a connector system according to claims 1, 10 and 18, a plug connector according to claim 27 and a retainer according to with claim 28. Invention Summary
    [0011] According to the invention, there is provided a connector system comprising a plug connector and a retainer that is adapted to be inserted into a corresponding socket. The plug connector comprises a connector housing and at least one locking arm assigned to the connector housing, whereby the plug connector is adapted to be mountable with the retainer. For example, the locking arm can be mounted to the connector housing or can be formed as an integral part of the connector housing.
    [0012] As will be clear to persons skilled in the art, the retainer may be exemplarily mounted within the socket and may be equipped with short-circuiting means, such as a short-circuit clip, to short-circuit the pins of socket electrical connection. The plug connector may be equipped with means to disable the short circuit when inserting the plug connector into the socket. In a preferred configuration, the retainer also serves as a mechanical connection element between the plug connector and the socket, that is, the plug connector is mechanically coupled to the socket via the retainer. In this way, advantageous locking elements of the plug connector, such as the locking arm, are not restricted in dimension or function by the dimensions or design of the socket, which, as is known to persons skilled in the art, is generally a component preset. In a preferred configuration, the connector system is not equipped with locking elements for direct mechanical engagement of the plug connector to the socket.
    [0013] According to the invention, the connector system comprises at least one deflection part to deflect the locking arm when assembling the plug connector with the retainer, the deflection part being shaped so that the deflection provide added resistance against further movement of the plug connector in the retainer. In a preferred configuration, the locking arm is equipped with a preferably inwardly directed locking projection, which is adapted to engage the deflection part, when assembling the plug connector with the retainer, such that the locking arm deflects outward in a direction essentially perpendicular to the mounting direction. For example, due to the deflection of the locking arm by the deflection part, the locking arm can be tilted against the deflection part. With further movement of the plug connector towards the socket, the deflection increases, thereby also increasing the pressure of the locking arm and thus providing greater resistance against further movement of the plug connector.
    [0014] According to the invention, the connector system comprises at least one release part adapted to allow a release deflection of the locking arm, where the release part is shaped so that the release deflection does not offer resistance against movements back of the plug connector. For example, the release part can be shaped such that, if the locking arm presses against the release part and the plug connector is moved towards the socket, the locking arm is deflected in such a way as to reduce the pressure. Thus, no shape needs to be applied to deflect the locking arm and therefore no resistance is offered against further movement of the plug connector.
    [0015] According to the invention, the connector system comprises at least one locking part adapted to allow the locking of the locking arm to lock the plug connector. For example, when fully inserting the plug connector into the socket, the locking arm may lock behind a stopping surface of the connector system to lock the plug connector in the fully inserted position into the socket. The deflection part, the release part and the locking part can all be provided on the retainer, or all on the locking arm. Alternatively, one or two of these parts may be provided on the retainer, while the other or two of such parts may be provided on the locking arm. Preferably, the deflection part, the release part and the locking part will all be provided in the retainer.
    [0016] In a preferred configuration, the deflection part and the release part are arranged so that, in assembling the plug connector with the retainer, the resistance offered by the deflection of the locking arm reaches a threshold value, before the deflection release of the locking arm is allowed. For example, the deflection part and the release part can be arranged so that the locking arm engages the deflection part before it can engage the release part. When engaging the locking arm in the deflection part and moving the plug connector towards the socket, the locking arms may be deflected outwards.
    [0017] Therefore, due to the increased deflection of the locking arms after the movement of the plug connector, the locking arms are progressively forced or pressed against the deflection part, due to the increasing spring force of the locking arms. Thus, the resistance against further movement, i.e. the insertion force, is increased, preferably up to a threshold value. In a preferred configuration, the threshold value corresponds to an insertion force magnitude within the range of 1N to 100N, preferably within the range of 10N to 90N, more preferably within the range of 20N to 80N, most preferably within the range of 30N to 70N, more preferably within the range of 30N to 60N, and ideally preferably within the range of 35N to 45N.
    [0018] In a preferred configuration, the deflection part, the releasing part and the locking part are integrally provided in an element called "GO/No Go", where the releasing part is disposed between the deflection part and the locking part. As an example, a resulting GO/No GO mechanism might be as follows. After inserting the plug connector into the socket, the locking arm of the plug connector engages with the deflection portion. Upon further movement of the plug connector in the insertion direction, the resistance against further movement increases, due to the increased deflection of the locking arm. After the resistance reaches a limit value, the locking arm engages with the release part. Thereafter, no resistance will be opposed to any further movement of the plug connector in the insertion direction, and when the plug connector is fully inserted and the locking arm has passed the release part, the locking arm will engage with the locking, ie in one example the locking projection of the locking arm, for example, will engage behind the stopping surface of the locking part so that the plug connector is locked in its fully inserted position.
    [0019] This mechanism is called the GO/No GO Mechanism because, preferably, in the case where the plug connector is introduced into the socket by a human operator, without sufficient force, the plug connector will not be inserted. In the other case, when the operator presses with enough force to overcome the resistance, due to a relatively large resulting pressure moment, the operator will not be able to leave the plug connector inserted only halfway, but will automatically press the plug connector until its fully inserted position.
    [0020] In an alternative configuration, according to the invention, a connector system comprising a plug connector and a retainer is provided, characterized in that the retainer is adapted to be inserted into the corresponding socket. The plug connector comprises a connector housing and at least one locking arm, which is assigned to the connector housing. The plug connector is adapted to be mountable with the retainer. The locking arm comprises an inwardly directed locking projection which is adapted to fit against the locking portion of the retainer when the plug connector is mounted with the retainer to lock the plug connector to the retainer. Therefore, the plug connector is advantageously locked in the retainer, which, in a preferred configuration, is provided with engaging elements for mechanically coupling the retainer to the socket. Thus, in the connector system in assembled condition, the plug connector is mechanically connected to the socket through the interaction of the locking projection of the locking arm with the retainer.
    [0021] In another alternative configuration, a connector system is provided comprising a plug connector and a retainer, where the retainer is adapted to be inserted into the corresponding socket. The plug connector comprises a connector housing and at least one locking arm assigned to the connector housing and the plug connector is adapted to be mountable with the retainer. The locking arm comprises a locking section adapted to mechanically connect to the locking part of the retainer and a release element adapted to be actuated to release the locking section from the locking part. The locking arm is pivotally connected to the connector housing by means of a pivot element disposed between the locking section and the releasing element, so that after actuation of the release element, the locking section is released from the locking part.
    [0022] In a preferred embodiment, the plug connector comprises at least one contact element adapted to electrically contact a socket contact element when a plug connector is mounted on the retainer and the retainer is mounted on the socket. Therefore, when the retainer is mounted in the socket, after mounting the plug connector on the retainer, the electrical contact element does not come into electrical contact with the contact element when the plug connector is in the position where the locking is deflected by the deflection part.
    [0023] Therefore, if, for example, the deflection part is a first part of a GO/No GO element, as described above, it is ensured that the electrical connection between the plug connector and the socket can only be established after that the plug connector is moved past this first blocking part of said GO/No GO mechanism. Thus, electrical and mechanical coupling of plug connector and socket can only be achieved at the same time. Furthermore, while the locking arm is deflected by the deflection part, such as, for example, when the plug connector is positioned in the first blocking position of the GO/No GO mechanism, an operator can visually detect that the plug connector is still is not properly attached to the socket. Thus, the GO/No GO mechanism described above can provide a means of visual detection so that an operator can ensure correct connection of the plug connector and socket when the plug connector is fully inserted into the assembled airbag connector system. In addition, it will also be possible to electrically detect the connection of the plug connector and the socket, because, as described above, the electrical connection and the mechanical connection of the plug connector in the connector system can only be obtained at the same time.
    [0024] It should be noted that the present invention can be implemented, for example, in an airbag connector system where the retainer is an "airbag detonator" retainer and the socket is a so-called "airbag detonator" socket. Description of drawings
    [0025] In the following, the invention is described in an exemplary manner, with reference to the attached figures, where:

    [0030] Figure 5 shows the retainer of Figure 4 from a different perspective;
    [0031] Figure 6 shows the retainer of figures 4 and 5 mounted in a socket;
    [0032] Figures 7A to 7C show cross-sectional views of a plug connector and a retainer inserted into a socket, characterized in that the plug connector assembly process is illustrated;
    [0033] Figure 8 shows a section through a connector system, with the plug connector partially assembled; and
    [0034] Figure 9 shows a diagram illustrating the insertion force of the plug connector as a function of the position of the plug connector with respect to the socket.
    [0035] Figure 1 shows a plug connector 100 to be used in connection with an airbag connector system. As can be seen, the plug connector is provided with a connector housing 101 which is closed off by a cap 104. The connector housing 101 is provided with a connecting tube 160 with a safety ring 161. The plug connector 100 it is further provided with two locking arms 102 which are integrally shaped with the connecting tube 160. The locking sections 130 of the locking arms 102, which are provided with inwardly directed locking projections 131 (see also figure 2, below ), are cut into the connecting tube 160. The locking arms 102 are connected to the connecting tube by means of flexible parts (connection bridges) 141, which are parts of the intermediate parts of the locking arms. Furthermore, the locking arms 102 are provided with release elements 150 which can be pressed inwardly against the connector housing 101 so that the locking arms 102 can be hinged around the hinge elements 140, i.e. , around said intermediate parts between the flexible parts 141.
    [0036] With reference to Figure 2, it can be seen that the connecting tube surrounds two contact terminals 121, which are received within insulating tubes 122 connected to the connector housing 101. As will be clear to persons skilled in the art , the plug connector is a “scoop-proof” plug connector, ie if the plug connector is incorrectly inserted into the corresponding detonator socket (shown below in figures 4 to 6), at a false angle, for example , the snap ring 161 will cover a part of the socket, in order to prevent further insertions and especially damage to the contact pins. Thus, the contact terminals can only come into contact, for example, with corresponding contact elements, ie socket contact pins, if the plug connector is correctly oriented for insertion. Here, as an example, references are made to plug connector contact terminals (female) and socket contact pins. However, as will be evident to persons skilled in the art, the plug connector, similarly, could be provided with contact pins, while the socket could be provided with contact terminals.
    [0037] Figure 3 shows an expanded view of the parts of the plug connector 100, in which the cap 104 has been disconnected from the connector housing 101, so that the internal components become visible. As can be deduced from Figure 3, in the assembled condition, locking tabs 106 which are provided on each side of the cover 104 (only two are visible, due to perspective) engage behind the corresponding locking faces 108, to lock the cover 104 in the connector housing 101. Between the cover 104 and the connector housing 101, electrical contact elements of the plug connector can be seen, i.e. contact terminals 121, in electrical connection with the cables 127 which, in the connector system at mounted condition, they serve, for example, to connect the socket to the control electronics of the airbag. Between the cables 127 and the contact terminals 121, an example of a ferrite element is shown.
    [0038] Figures 4 to 6 show a retainer 200. The retainer is adapted to be inserted into a socket and is thus provided with coupling elements 231, i.e. stop pawls 231, to lock the retainer 200 within a socket 300, as shown in figure 6. The retainer 200 is provided with an eight-shaped opening 221 which, in the assembled condition of the retainer 200 and socket 300 surrounds the contact pins 221 of the socket 300 (see figure 6) and which, after assembling the plug connector 100 on the retainer 200, inside the socket 300, it can receive the insulating tubes 122 from the connector housing 101 (shown in figure 2 above).
    [0039] Figures 7A to 7C illustrate the process of inserting plug connector 100 into socket 300. As seen in these three figures, retainer 200 is shown fully inserted into socket 300, surrounding two contact pins 321 of the socket. For illustrative reasons, the contact terminals 121 of the plug connector are not shown in the figures, so that only the inside of the insulating tubes 122 is visible.
    [0040] When the plug connector is positioned as shown in Figure 7A, the angled surfaces 132 that are provided on the locking projections 131 of the locking arms 102 touch part of the deflections 202 of the retainer 200. The deflection part 202 is formed of so that, after insertion of the plug connector 100, in the insertion direction, 401 into the socket 300, the part of the deflections deflect the locking arms outwards. As will be clear to persons skilled in the art, due to the deflection, the angled surfaces 133 are pressed against the deflection part 202, where, after a further movement of the plug connector 100 in the insertion direction 401, the deflection, and so on the pressure increases. More force is required to deflect the locking arms 102 further outward, so that, due to the deflection of the locking arms and the pressure of the angled surfaces 133 against the portion of the deflections 202, greater resistance is provided against further movements of the connector of plug, in the insertion direction 401.
    [0041] As can be seen in these figures, the deflection part 202 is shaped in the emerging part 201, that is, the GO/No GO element 201, next to the releasing part 204. Therefore, the GO/No GO element 201 is shaped so that after the locking arm reaches the maximum deflection and such resistance has reached a threshold value, after any further movement of the plug connector 100 in the insertion direction 401, the locking projections 131 touch the releasing part 204 ( see figure 7B). In other words, when the locking projection 131 of the locking arm 102 is positioned between the deflection part and the releasing part 204, the deflection of the locking arm 202 is at its maximum, so that the pressure of the locking arm is the maxim. Therefore, the resistance provided by the deflection of the locking arm reaches a threshold value just before the locking arm touches the release part 204.
    [0042] Preferably, the threshold value corresponds to an insertion force within the range of 1N to 100N, preferably within the range of 10N to 90N, more preferably within the range of 20N to 80N, even more preferably within in the range of 30N to 70N, even more preferably within the range of 30N to 60N, and ideally preferably within the range of 35N to 45N.
    [0043] As can be seen in Figure 7B, if the plug connector 100 is pressed in the insertion direction 401 with a force that exceeds the insertion force required to overcome the resistance, the locking projection 131 may be moved, after the deflection part 202 is passed, so that the locking projection 131 is in contact with the releasing part 204. As can be seen from the figure, as the locking arms are still deflected outwards, they are forced against the release parts 204. After a subsequent movement of the plug connector 100 in the insertion direction 401, due to the shape of the release part 204, the locking arms 102 are free to fold inwards. Due to the intrinsic tension of the locking arms, caused by the outward deflection exerted by the deflection part, the following inward deflection, exerted by the interlocks, automatically follows. In this way, no extra force needs to be applied, and, in other words, this deflection, ie the release deflection, offers no resistance against subsequent movements of the plug connector, in the insertion direction 401. As can be seen from middle of Figure 7C, after the full insertion of the plug connector 100 into the detonator socket 300, the locking projections 131 lock inwards, behind the locking part 206 of the detonator retainer 200, to lock the plug connector 100 into the retainer 200. Since retainer 200 is equipped with 231 engagement elements (see figures 4 and 5) to mechanically couple retainer 200 to socket 300, in the assembled airbag connector configuration, as shown in figure 7C, the plug connector 100 is mechanically connected to socket 300 via retainer 200 only.
    [0044] As can be seen in figures 7A to 7C, preferably the deflection part 202, the release part 204 and the interlocks part 206 are integrally provided in a GO/No GO element 201, where the release part 204 is disposed between the deflection part 202 and the locking part 206. As described above, the GO/No GO element 201 provides a GO/No GO mechanism for the plug connector 100, after movement of the plug connector 100 into the socket 300 If the plug connector 100 is positioned in an initial position, as shown in figure 7A, and pressed from there into socket 300 with an insertion force that does not exceed the required threshold value, the plug connector 100 cannot be inserted in socket 300. As can be seen in Figure 7A, as the retainer 200 extends out of the socket 300 so that the angled faces 133 of the locking projections 131 touch the part of the deflections 202, before the plug connector 100 is inserted into socket 300, in pos tion of plug connector 100, no electrical connection between contact pins 321 of socket 300 and contact terminals 121 (not shown) can be established.
    [0045] If the insertion force exceeds the threshold value, the plug connector 100 can be moved in socket 300. Preferably, the force required to exceed the threshold for insertion should be sufficiently large, so that if an operator pushes with such force, the plug connector 100 is directly inserted into its final position, in which the locking projections 131 touch the locking parts 206, as shown in figure 7C.
    [0046] As will be clear to persons skilled in the art, in order for the aforementioned GO/No GO mechanism to be provided, the dimensions of the GO/No GO 201 element must be selected appropriately. As can be seen in Figure 7C, for this purpose, preferably the deflection part 202 should have an extension Ld and the releasing part 204 an extension Lr, where both extensions are measured in parallel with the insertion direction 401 of the connector. plug 100 and where Ld is shorter than L. Preferably, the Ld/Lr ratio should be within a range of 0.05 to 0.8, more preferably within the range of 0.1 to 0.75, even more preferably within the range of 0.15 to 0.5 and ideally preferable within the range of 0.2 to 0.3.
    [0047] As can be seen in Figure 8, the release elements 150 of the lock arm 102 can be actuated by an operator, that is, the release elements 150 of the lock arms can be pressed inwards towards the housing of the connector 101, whereby, as can be seen in this figure, the locking section, i.e. the locking projection 131 is released from the locking part 206 by the articulation of the locking arm 102 around the hinge element (the flexible parts, as seen in figure 1). If release elements 150 are actuated as shown in figure 8, plug connector 100 is free to be removed from socket 300.
    [0048] Figure 9 shows a diagram illustrating the insertion force required to move a plug connector in the insertion direction into a socket as a function of the position of the plug connector with respect to the socket.
    [0049] As can be inferred from Figure 9A, the locking projections 131 come into contact with the part of the deflections 202 before the plug connector 100 can be inserted into socket 300. Thus, before the contact terminals (not shown) of the plug connector 100 can come into electrical contact with the socket contact pins 321, the insertion force increases linearly, until a threshold value of 40 N is reached. Only if the insertion force exceeds this threshold value can plug connector 100 be fully inserted into socket 300 so that contact terminals 121 can make full contact with contact pins 321. The diagram thus illustrates , the GO/No GO mechanism, as described above.
