    2 extending inwardly the catheter and a longer catheter extending from the free end of the shorter catheter, forming a sawtooth-shaped locking lug. The attachment to the inside of the sleeve portion can be articulated, for example by the material thickness of the locking lug being thinner at the attachment, or by the locking lug being wholly or partly formed in a softer material in this area.
    In one or more embodiments, the sleeve portion has at its one end a radially inwardly extending abutment shaft adapted to abut against an upper edge of the base part. This abutment can also consist of two segments and wherein the two segments can be separated by an area corresponding to the extent of the locking lug in a circumferential direction. The abutment means can also consist of one segment, three segments, four segments, five segments or more, in separate embodiments or combined with previous embodiments.
    In one or more embodiments, the connector comprises position indicators which visually or tactilely indicate locked and / or disengaged position. A color, symbol, snap lock or the like may indicate when the connector has reached a certain position, preferably a locked and / or a disengaged position. The position indicator can also show a position by emitting a light signal.
    The locking member itself may in one or more embodiments consist of a pin, preferably a spring-loaded pin biased in a locking or disengaging direction.
    Two main embodiments of the connector are a corded connector, such as a splice connector, or a connector for fixed installation, such as a socket, and these two main grooves can be combined with any other embodiment unless it is technically impossible.
    The locking member uses in one or more embodiments a frictional engagement with the male contact. This can mean that the locking member directly engages the male contact and that this intervention locks the male contact with a gradually increasing force, ie the more the locking member is tightened the tighter the male contact is held. However, it can also mean, which is usually preferred, that the locking means blocks a path that some part of the male contact must pass in order to break an electrical contact with the female contact. This still involves a frictional intervention, but the interaction does not begin until the male contact begins to detach from the female contact. The locking means can for instance be adapted to be arranged freely relative to a guide lug of a male contact arranged in the coupling device, wherein frictional engagement only exists when the male contact is brought in a disengaging direction.
    In another aspect, the present invention provides a method of mounting a connector according to any preceding claim, comprising the step of applying a locking member comprising locking means to a base member comprising a female connector. 3 Further examples are given in the detailed description.

    Fig. 2 is a perspective view of a locking member according to a first embodiment of the present invention.
    Fig. 3 is a perspective view of a composite connector according to a first embodiment of the present invention.
    Fig. 4 is a schematic view of a second embodiment of the present invention.
    Detailed Description Fig. 1 is a perspective view of a base portion of a connector according to a first embodiment of the present invention. The base part 102 consists of a hen contact, adapted to receive a mating male contact (not shown). For maximum use of the advantages of the embodiment, the male contact is corded with a drill, a lawnmower, or other equipment where moving the equipment can cause a breakage of the connection. According to a broader definition, the embodiment is suitable for any connection where a connection break can cause worries, computers, wires that are pulled where people pass, ie. almost every clutch.
    Extending from the base part 102 in use is a cord from a first end while a second end is adapted to receive the male contact, preferably a grounded male contact.
    The base part 102 comprises for the purpose a larger, substantially cylindrical opening 104 with space for the female plate ground plate, at 106, and guide grooves 108. The guide grooves 108 cooperate with non-conductive guide lugs of the male connector, which ensures that the plug (male connector) ends up correctly. various reasons should not be used with the female connector nor can it be connected to it.
    Several features of the base part should be known to those skilled in the art as electrical connectors largely have a standardized design, for example by CEE 7/4, CEE 7/7, CEE 7/16, CEE 7/17 etc. It should be pointed out that these examples should not be construed as limiting the present invention, which is defined by the appended claims.
    According to the embodiment shown in Fig. 1, the base part 102 further comprises a pair of at least partially continuous recesses 110, 10 '. The recesses 110, 110 'extend in a circumferential direction at the other end of the base part. What is meant by onyx direction should be obvious in Fig. 1, i.e. a direction extending in a direction around the closest 4 circular circumference of the base part. Circumference should also be universal for base parts with a shape other than circular, but to further clarify the circumferential direction is a direction which is orthogonal to an axial direction extending in the longitudinal direction of the base part, or the contact insertion direction if this is preferred. and at reference numeral 110 'the recess is shown from the inside. A comparison shows that the recess has a greater extent on the outside than is the case on the inside. This need not be central to the invention as such, as there are also embodiments without continuous recesses, or recesses with other size ratios. As shown at 110 ', the recess on the inside of the base member extends over the entire extent of the guide groove 108 in the transverse direction (perpendicular to its axial extent or longitudinal direction).
    Inside the female part, a contact part (not shown) is arranged, which in a known manner provides the necessary coupling details for phase, zero, earth, etc., all in accordance with standard female contacts. The contact part can be joined to the base part in a non-releasable way, such as glued or co-molded, or fastened with snap locking, screw joints or other more releasable way.
    Fig. 2 shows a locking member mating with the base member 102 according to the first embodiment of the present invention. The locking part 120 comprises a sleeve portion 122 whose inner diameter substantially corresponds to the outer diameter of the base part 102 at the other end thereof. The locking part 120 further comprises a locking lug 124 extending radially inwardly from the sleeve portion 122 constituting a locking member. In the present embodiment, the locking lug has a sawtooth shape consisting of a longer "catheter" 126 and a shorter "catheter" 128, the shorter catheter 126 extending substantially radially inwardly, seen from the inner diameter of the sleeve portion. With the corresponding wording, if not completely geometrically correct, the "hypotenuse" 130 of the locking lug corresponds to its attachment to the inner circumference of the sleeve portion 122. This attachment is preferably of a permanent kind, effected by gluing, welding or by forming the locking lug 124 in a part with the sleeve portion 122. Furthermore, the locking part 120 has an inwardly extending abutment shaft 132 at one end of the sleeve portion 122. The abutment end may in one or more embodiments extend around the entire circumference of the sleeve portion 122, but in the present embodiment consists of two pieces. segments 134, 136. The purpose of the abutment flange is explained in more detail below. In short, each part of the locking part shown in the embodiment can be varied in its design without departing from the inventive idea. The design of the locking part is rather limited by the function it has to perform, and for example the locking lug can have a completely different design. The locking lug could also be hinged at its attachment to allow rotation in at least one direction to facilitate assembly. Such a hinge can consist of a weakening in the longitudinal direction of the attachment, for example because the goods are locally thinned somewhat. The outside of the locking part 120 or the outside of the sleeve part 12 may be provided with a gripping simplifying pattern in the event that the locking part is turned into engagement with the male contact. In the present embodiment, the grip-simplifying pattern consists of a repeated axial rib of the outside of the locking part. A further selectable structural detail is the notch 137 which extends in an axial direction at the inside of the locking part. This insert is adapted to cooperate with one or two similarly extending ridges (not shown) arranged on the outside of the female part in order, for example, to partially block the locking part in its end positions (locked position and disengaged position). According to another embodiment, the ridge is arranged on the locking part and the groove on the female part, and also the number may differ so that there are, for example, several grooves 137 or ridges which may be opposite each other or arranged in another way to constitute position indicators.
    Fig. 3 shows the locking part 120 arranged on the base part 102 according to an embodiment of the present invention. The reference numerals shown in Fig. 3 correspond to those previously used in the description of Figs. 1 and 2, and it should therefore be easy to identify the various parts and portions. It is noteworthy that the locking lug 124 extends through the recess 110. This enables a central function of this embodiment of the invention. The design of the locking lug 124 gives it an effectively increasing radial extent and by turning the locking part 120 in its position on the base part 102 it can enter and block the guide groove 108 in an upper end thereof. As a result, the locking lug 124 can co-operate with a guide lug of the male contact and in this way lock the male contact in a position where it is electrically connected to the female contact. The way in which the locking lug engages with the male contact may vary, but it would be most correct to call it a frictional intervention in a broad sense. In your case, a male contact has non-conductive guide lugs which have only a limited longitudinal extension. This allows the locking lug to enter and lock when the guide lug has passed the recess 110 'and thereby provide a direct blocking of the guide groove 108. This is the preferred process. In the event that the guide lug should have a longer extension, the locking lug 124 can engage in direct friction with the guide lug. Both methods provide a secure engagement with a portion of the male connector that is relatively insensitive to tensile load, at least when compared to the cord as such, or the male connector connector pin.
    The design of the locking lugs can, after the idea of invention has been completed, be likened to an optimization problem where one wants to achieve as secure a holding as possible without for that purpose weakening the base part in an unnecessary way.
    As mentioned earlier, the abutment ends 132 are constituted by two segments 134 and 6 134. This need not be the case, but in that the area between the two segments (if one follows the circumference along which they are arranged) coincides with one or more positions of the locking lug 124, it is easy to identify the position of the locking lug even if a male contact is connected. In the embodiment shown, the abutment surface makes a pause over the entire extent of the locking lug and thereby identifies both the beginning and the end thereof. This also applies to both locking lugs in this particular embodiment, even if only one locking latch is visible and even if it is not absolutely necessary to have two, or even one. An additional effect of a split abutment is also that the tool used in manufacturing can be made cheaper as it is easy to achieve shaping of a two-part tool without this tool interfering with any part of the locking part. The two segments can in turn be divided into more segments if desired.
    In the embodiment shown, the locking part 120 has two locking lugs, both of which extend through the base part. Again, it can be pointed out that it is a function to be achieved and even if the simplicity of the embodiment shown is appealing for your reasons, there are alternative embodiments. First, in your case, only one locking lug may be sufficient. The locking lug or locks need not be continuous, but instead a movable part can be arranged in the base part, whereby a construction corresponding to the locking lug, or rather a cam curve can engage with the movable part and thus enable this movable part to be engaged with any part of a male contact. An example of such an embodiment is shown schematically in Fig. 4. A continuous pin 124 'constituting a locking member extends through the edge of the base part, for example at a position corresponding to the recesses 110 according to Fig. 1. A distal part 140 of this pin can be actuated by a cam curve, a groove 138 of varying depth in a radial direction (left / right in the view shown in Fig. 4) of a locking part 120 ', wherein a proximal part 144 of the pin can be moved radially inwards (the whole pin is moved radially inwards) to enable intervention with a male contact. To enable unloading, the pin 124 'can be biased in an outward direction, for example by means of a coil spring 146. As with the locking lug, one or two pins can be arranged distributed around the circumference of the base part. According to another embodiment, the pin may be biased inwardly to ensure that a locked position is present unless the user performs an action to break the locked position, for example forcing the pins outwards. It is obvious that such a forcing movement can be effected in your various ways, for example by pulling the pins outwards, that the pins are attached to a lever so that a pressure results in said movement, that a rotation results in said movement, etc.
    According to another embodiment (not shown), a female connector is provided in the form of a socket for fixed installation. A difference between this embodiment and the previously shown 7 is that it is generally arranged indoors or at least reasonably weather-protected, and that there is generally more space available. As a result, the technical solution does not have to be as minimalist and the number of moving parts and the complexity of these parts can, but must not, be increased in favor of a more aesthetically pleasing solution. However, the same basic principle still applies that a locking mechanism frictionally locks the male contact by causing a pin or other locking means to block the guide groove corresponding to the guide groove 108. This locking means may be spring-loaded towards the locked position, or moved between locked and disengaged positions by a user. Spring-loaded or not, the plug socket should include a release means with which the user can disconnect the male connector. In this embodiment, the base part consists of the plug socket.
    Additional examples could be eccentric tensioners affecting pins or lugs and one skilled in the art given the above embodiments could reasonably provide variants on the same theme, but most of these variants would require greater impact on the base member and / or moving parts. If one deviates from the main theme of the present invention, one could also have hooks that fall over the male contact, like the locking straps on the cover of a vehicle headlight, but again this would probably constitute a more complicated solution.
    The manner in which the locking member 120 is mounted on the base member 102 may vary with the materials used. If neither the locking part nor the base part has a divisible construction, it may be suitable to arrange the locking part on the base part before a contact part is arranged in the base part and makes it a working female contact. This method allows the base part to be slightly deforested so that the locking part can be arranged in the right place, and once the contact part is arranged in the base part, it stabilizes the entire construction and makes it more difficult for the locking part to end up out of position. The base part can also be heated before mounting to further increase its flexibility.
    The base part may consist of rubber, polymer-modified rubber or suitable polymers.
    What is considered appropriate may vary with the area of use. The locking part suitably consists of a pre-sprayable polymer, which is relatively dimensionally stable, which is advantageous for the embodiments shown in Figs. 2 and 3.
    One skilled in the art will appreciate that the invention as described in the present application is not limited to the embodiments described by way of example.
    These embodiments may be modified and combined freely within the scope of the present invention as defined by the appended claims.
