DETAILED DESCRIPTION

[0027] The figures may contain in some cases simplified, schematic representations. Identical reference signs are sometimes used for similar but possibly non-identical, elements. Different views of similar elements might be scaled differently.

[0028] FIG. 1 shows a plug connector 1 according to an embodiment of the invention in a perspective diagram. The plug connector 1 has a rectangular cross section and is therefore also referred to as a rectangular plug connector. The plug connector 1 has a cable gland 2, which at the same time also forms a strain relief for a connected multi-strand cable (not shown).

[0029] The plug connector 1 has a connection side A, to which the cable or its conductors are connected, and a plug-in side S, which is guided in the plug-in direction SR to a mating connector or a socket (neither shown).

[0030] The plug connector 1 has locking hooks 3, which engage in snap-in openings provided therefor in a mating connector or a socket for reversible locking. The locking hooks 3 can correspondingly be detached again by an actuator 4 situated on the outside of the plug connector housing.

[0031] In FIG. 2, the plug connector 1 is shown partially cut away. As a result, the receiving regions 5 in which the contact elements 6, 6 are arranged can be seen. In the receiving regions 5 there are openings 7 into which the contact elements 6, 6 are inserted.

[0032] FIGS. 6 and 7 show embodiments of a contact element 6, 6. The contact element 6, 6 has a crimping region C for the attachment by crimping of the conductor to be connected. Furthermore, the contact element 6, 6 has two grip regions Z1 and Z2 that can be gripped by the bridging element 10 for the electrical bridging of the contact elements 6, 6.

[0033] In FIG. 5, the operating principle of a bridging element 10 can be seen easily. The bridging element 10 comprises or consists of a conductive material. The bridging element 10 has a substantially elongate strip from which multiple gripping hands 8, exactly three in the case shown, project perpendicularly. The gripping hands 8 have substantially the same operating principle as a hand of a toy brick minifigure. The gripping hands 8 each surround the grip region Z1 or Z2 of the contact element 6, 6 assigned thereto.

[0034] In FIG. 4, the plug connector 1 is shown with a partially cut away plug connector housing 11 so that the viewer can see the integrated contact insert 12. The contact insert 12 has two lateral recesses 9. The bridging element 10 can be inserted laterally into the contact insert 12 into these recesses 9. In the process, the gripping hands 8 of the bridging element 10 enclose or surround the contact elements 6, 6 assigned thereto, as shown in FIG. 5. FIG. 4 shows only one bridging element 10, which is situated in a recess 9. The second recess 9 is kept free to show the viewer that it is possible to grip the contact elements 6, 6 or the grip regions Z thereof through it.

[0035] In the embodiment of the plug connector 1 in FIG. 4, a cap (not shown) is attached after the insertion of the contact bridges in order to close the open region again so that it is not touchable or accessible from the outside.

[0036] In FIG. 4, it can be seen that the bridging elements 10, if two bridging elements 10 were shown here, are arranged parallel to one another and on different planes E1, E2.

[0037] FIG. 6 shows an embodiment of a contact element 6. As viewed in the plug-in direction SR, grip regions Z1, Z2 and crimping region C alternate.

[0038] Shown in FIG. 7 is an alternative embodiment of a contact element 6. Viewed in the plug-in direction SR, the contact element 6 has a crimping region C first, which is followed by two grip regions Z1, Z2 arranged one behind the other.

[0039] Even though various aspects or features of embodiments of the disclosure are each shown in combination in the figures, it is apparent to a person skilled in the art unless otherwise indicatedthat the combinations shown and discussed are not the only possible ones. In particular, corresponding units or feature combinations from different embodiments may be interchanged with each other. Put another way, aspects of the various embodiments described above can be combined to provide further embodiments.

[0040] In general, in the following claims, the terms used should not be construed to limit the claims to the specific embodiments disclosed in the specification and the claims, but should be construed to include all possible embodiments along with the full scope of equivalents to which such claims are entitled.
