- a jack plug can be inserted as a mating connector into the central insertion opening and a shaft of the jack plug and a contact bulb of the jack plug arranged at the free end of the shaft can be electrically contacted.
- EP 1401056 A1 discloses a connector receiving part of an electrical plug connection, in particular for Audi oan turns, the housing of which has a central receiving space which is delimited by a partition with an inside and an outside, and an annular receiving space surrounding the partition, with both receiving spaces being plug-in openings for a complementary mating connector.
- Both on the inside and on the outside of the intermediate wall electrical plug contacts are arranged, which have a metallic strip-shaped body, the egg nen fastening area and a protruding from the fastening area free arm with egg nem contact area at its free end and one between the contact area and the Has fastening area lying resilient area.
- the proposed contact element has a fastening area and a free arm projecting from the fastening area, with a contact area and a resilient area, the contact area being arched.

It also ensures optimal contact at any time and in any relative position of the contact pin and contact element.
- a variant is preferred in which the rotation increases steadily from the tangential section to just before the front end of the contact element.
- a contact element with a twisted front section can achieve the desired curvature in relation to the path of the contact pin in that the side edge cooperating with the contact pin is parallel to The longitudinal center of the contact element runs and the ge in the direction of deflection of the contact element see acute angle between the path of the contact pin and the side edge is caused by the rotation of the contact element.
- the contact element can be made easier, since only straight side edges are required, with a gentle Kraftver run in the course of inserting the contact pin and deflecting the contact element.

This relative movement with sliding along - similar to the principle of cutting a pair of scissors - takes place until the front section of the contact pin 8 has moved onto the flat top 144 of the contact element 14.
- the contact pin 8 can then either be pushed further forward or by rotating the complementary connector - for example in the course of a bayonet-like locking of the connector - transversely to the longitudinal axis of the contact element 14 away from the side edge 142 of the contact element onto its flat surface 144.
- a planar contact section 145 of the contact element 14 adjoining the side edge 142 is in contact with the contact pin 8 and ensures optimal electrical contact.
- the contact element 14 is convexly curved in its front, deflectable section 146 against the deflection direction.
- the apex region of the curved section 146 of the Mixelemen tes 14 is preferably in the fully inserted complementary connector in the area of the vorder th section of the contact pin in order to ensure optimal contact. This ensures an optimal pressing action of the contact element 14 on the contact pin 8 and also ensures that the largest possible contact area is present between the two electrical contacts.
- the preferred embodiment of a contact element 14 also has a convex curvature in the direction of the contact pin 8, which is particularly advantageous with connectors, in which when the cable connector is inserted into the built-in connector, the contact pin 8 of the cable connector first slightly outside the longitudinal center of the curved one and elastically deflectable section 146 (in Fig. 16 approximately parallel to the contact element 14, but slightly above its longitudinal center; in Figs.
- the contact pin 8 is first guided along the side edge 143 of the contact element 14, similar to the legs of a pair of scissors, and thereby directs the Curved section 146 continues against the curvature until finally - and typically with the greatest deflection of the contact element 14 - the front section of the contact pin 8 of the cable connector runs onto the flat surface 144 of the curved section 146 of the contact element 14.
- the cable connector and built-in connector are then rotated relative to each other in order to lock the connector. This movement takes place in Fig.
- the contact pin 8 would be perpendicular to the plane of the drawing and would be slid from left to right along a circular arc section to the right onto the flat surface 144 of the contact element 14 in order to finally come to lie in the contact area 145.
- This second curvature in the front section of the curved section 146 of the contact element 14 on the contact pin 8 of the cable connector which is in any case parallel to the direction of the deflection, is a curvature transverse to the longitudinal axis of the contact element 14 and perpendicular to the direction of the deflection of the section 146 can also only relate to one side edge 142 which is closer to the contact pin 8 and which first comes into contact with the contact pin 8 of the cable connector when the plug connection is established.
- the lateral, second curvature can, however, also affect both side edges, which then leads to a sickle-shaped shape of the deflectable section 146 transversely to the deflection direction.
- the apex area 147 of the lateral curvature is preferably in the foremost part of the curved section 146, between the front end of the contact element 14 and the area 145 of the curved section 146, on the flat surface of which the foremost section of the contact pin 8 lies when the complementary connector is fully inserted .
- This allows the contact pin 8 to slide along the side edge 142 when the cable connector is inserted, the contact point between contact pin 8 and contact element 14, in particular its curved section 146, shifting more and more and from the greatest distance to an imaginary connecting line of contact pin 8 with the Central axis of the cable connector finally wanders towards this connecting line.
- the longitudinal center of the contact area 145 of the advantageously migrates Contact element 14 in the connecting line and contact pin 8 and contact area 145 lie conditions with optimal contact to one another, both in terms of the contact surface and the contact force.
- the side edge 142 of the contact element 14 coming into contact with the contact pin 8 can - in a projection in the direction of the deflection of the front section of the contact element 14 - also be curved in relation to the path of the contact pin 8, that the front section leads around its own axis is twisted.
- the extent of the twist can preferably also change along the length of the deflectable section 146 of the contact element 14, the greatest twist being provided in the foremost area, which area comes into contact first with the contact pin 8 of the cable connector.
- 17 shows a cross section transverse to the longitudinal direction of the contact element 17 shortly before this point, along the line XVII-XVII in FIG. 16, so that the strongly twisted section of the contact element can be seen from the direction of the contact pin 8.
- FIG. 18 The next cross-section in FIG. 18 is set a little further from the front end, along the line XVIII-XVIII in FIG. 16, and shows that the twist at this point is already significantly less than in FIG. 17.
- FIG Projection in the direction of deflection of the contact element 14 is therefore the side edge 142 so a little further away from the longitudinal center axis, as it would correspond to a real curvature of the front portion 146 of the contact element.
- the curvature is then already very small, as can be seen in FIG. 19, which shows a cross section along the 16 shows line XIX-XIX.
- This section of the contact element 14 then passes immediately behind it - offset in the direction of the contact lug 141, into the flat section 149 which is not twisted and is therefore parallel with respect to the section 149 fixed in the rear wall 15.
- the following section of the deflectable section 146 then goes from the apex of the curvature without twisting to the flat, plate-shaped section 149, which is used for fastening in the rear wall 15, and then merges into this section 149.
- FIG. 20 in cross section, which is taken along the line XX-XX of FIG. In summary, it could also be expressed in such a way that the rotation increases steadily from the tangential section to just before the front end of the contact element.
- the rotation about its own longitudinal axis of the ausschba Ren section 146 results in a spatial path for the contact point of the contact pin 8 of the cable connector pushed into the housing 1, but from radially outside the contact pin 8 in the direction of the deflection of the contact element 14 seen from a larger lateral distance to the longitudinal center axis of the contact pin 8 up to congruence equality with a connecting line that runs parallel to the direction of deflection and goes through the center axis of the contact pin 8.
- the desired curvature in relation to the path of the contact pin 8 arises in this projection.
- the tangent to the Be tenkante 142 runs at each contact point along the above-mentioned path skewed to the longitudinal center axis of the contact pin 8 or to the longitudinal center axis of the contact element 14, which is through the The longitudinal center axis of the section 149 or the contact tab 141 is given.
- the foremost section 148 of the deflectable section 146 of the Needlesele Mentes 14 is preferably designed as a guide section which is displaceable in a guide structure of the housing 1, in particular the partition 4, parallel to the longitudinal axis of the housing 1. Movements of the foremost end portion 148 of the contact element 14 transversely to the sen longitudinal direction are prevented by the guide structure, typically sack-like recesses at the end of the recess in the intermediate wall 4 or at the end of the intermediate wall 4 worked out and the contact element 14 receiving groove.
- the pushing away of the contact element 14 by the contact pin will also result in a longitudinal movement, ie a movement in the direction of the main longitudinal axis of the housing 1, towards the front in the direction of the insertion opening or visible surface of the housing 1.
- a longitudinal movement ie a movement in the direction of the main longitudinal axis of the housing 1
- the two electrical contact elements move mainly in their longitudinal direction and only to a small extent transversely to this longitudinal direction relative to one another, it does not necessarily require such a complex embodiment as described above.
- the contact in the central plug-in opening 2 in which a central pin 6 of the cable connector as shown for example in Fig.
- FIGS. 10 to 13 Such a contact element 13 for the central insertion opening 2 is shown in detail in FIGS. 10 to 13. It can also be seen here that the contact surface 135 lies essentially at the highest point of the convexly curved section 136 of the contact element 13.
- the contact element 13 preferably also has a resiliently deflectable tongue-shaped section 136, which is also convexly curved in the same way as with the contact element 14, against the direction of its deflectability, as can be clearly seen in FIG. 11.
- a resiliently deflectable tongue-shaped section 136 which is also convexly curved in the same way as with the contact element 14, against the direction of its deflectability, as can be clearly seen in FIG. 11.
- the end section 138 of the contact element 13 is also preferably guided parallel to the longitudinal axis of the built-in connector and the side edge 132 in the foremost section of the contact element 13 runs obliquely to the longitudinal center axis of the contact element 13 and obliquely to the path of the contact pin 9 when it is inserted into the insertion opening 2.
- the central plug-in opening 2 of the built-in connector can also be designed for the production of a plug connection with the contact pin 101 of a conventional jack plug - as shown in FIG. 3.
- the contact element 13 is then in addition to the contact area with the shaft of the contact pin 101 with contact areas for the contact bulb 102 located at the free end of the contact pin 101 of the jack plug.
- first contact lug electrically connected to the contact element 14 protruding outward into the insertion opening 3, from which contact can be made with the contact bulb 102 of the jack plug
- second contact lug electrically connected to the contact element 13 projecting into the interior of the inner insertion opening 2 , by which the shaft of the contact element 101 of the jack plug can be contacted
- a thrust element cooperating with the contact element 14 is advantageously present. This is for contacting the contact element 14 with the contact pin 9 of the cable connector when it is inserted from the annular connector extension in the direction of the central longitudinal axis of the housing 1 Ge.
