  • This second curvature in the front section of section 146 of contact element 14, which is curved in any case parallel to the direction of deflection, towards contact pin 8 of the cable connector is a curvature transverse to the longitudinal axis of contact element 14 and perpendicular to the direction of deflection of section 146. It can also only relate to the contact pin 8 closer to a side edge 142, which first comes into contact with the contact pin 8 of the cable connector when the plug connection is made. However, the lateral, second curvature can also affect both side edges, which then leads to a crescent-shaped shape of the deflectable section 146 transverse to the direction of deflection.
  • the apex area 147 of the lateral curvature is preferably located 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 planar surface of which lies the foremost section of the contact pin 8 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 pushed in, with the contact point between the contact pin 8 and the contact element 14, in particular its curved section 146, shifting more and more and moving from the greatest distance to an imaginary connecting line of the contact pin 8 with the central axis of the Cable connector finally migrates to this connecting line.
  • the longitudinal center of the contact area 145 of the Contact element 14 in the connecting line and contact pin 8 and contact area 145 are in optimal contact with one another, both in terms of the contact area and the contacting force.
  • the side edge 142 of the contact element 14 that comes 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 designed curved with respect to the path of the contact pin 8 in that the front section around its own Axis is twisted.
  • the extent of the torsion can preferably also change along the length of the deflectable section 146 of the contact element 14, with the greatest torsion being provided in the frontmost area, which area first comes into contact with the contact pin 8 of the cable connector.
  • the 17 shows a cross section transverse to the longitudinal direction of the contact element 17 just before this point, along the line XVII-XVII of 16 , so that the severely twisted section of the contact element can be seen from the direction of the contact pin 8.
  • the next cross section of the 18 is set on a little farther from the anterior end, along the line XVIII-XVIII of the 16 , and shows that the twisting at this point is already significantly smaller than in 17 .
  • the side edge 142 is therefore somewhat further away from the longitudinal central axis, as would correspond to a real curvature of the front section 146 of the contact element.
  • the curvature is then already very small, as in 19 can be seen, taking a cross-section along the Line XIX-XIX of 16 shows.
  • This section of the contact element 14 then transitions immediately behind it—offset in the direction of the contact lug 141—into the flat section 149 that is not twisted and therefore parallel with respect to the section 149 fixed in the rear wall 15 .
  • the following section of the deflectable section 146 then continues from the apex of the curvature without twisting to the flat, plate-shaped section 149, which is used for attachment in the rear wall 15, and then merges into this section 149.
  • This position is in 20 shown in cross section taken along line XX-XX of 16 is laid. In summary, it could also be expressed in such a way that the torsion 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 deflectable section 146 results in a spatial path for the contact point of the contact pin 8 of the cable connector inserted in the housing 1, which, viewed from radially outside of the contact pin 8 but in the direction of the deflection of the contact element 14, is from one greater lateral distance from the longitudinal center axis of the contact pin 8 up to congruence with a connecting line that runs parallel to the direction of deflection and passes through the center axis of the contact pin 8. In this way, the desired curvature occurs in this projection in relation to the path of the contact pin 8.
  • the tangent to the side edge 142 runs at each contact point along the above-mentioned path skew to the longitudinal center axis of the contact pin 8 or to the longitudinal center axis of the contact element 14, which passes through the longitudinal center axis of the section 149 or the contact lug 141 is given.
  • the foremost section 148 of the deflectable section 146 of the contact element 14 is preferably designed as a guide section which is mounted in a guide structure of the housing 1, in particular the intermediate wall 4, so that it can be displaced parallel to the longitudinal axis of the housing 1.
  • movements of the foremost end section 148 of the contact element 14 transverse to its longitudinal direction are prevented by the guide structure, typically bag-like recesses at the end of the recess in the intermediate wall 4 or at the end of the groove worked out in the intermediate wall 4 and accommodating the contact element 14.
  • a contact element 13 with a simpler shape.
  • a contact element 13 for the central insertion opening 2 is in the Figures 10 to 13 shown in detail. 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 tongue-shaped section 136 that can be deflected in a spring-elastic manner, which is also convexly curved in the same way as in the case of the contact element 14, counter to the direction in which it can be deflected, as in FIG 11 is clearly visible.
  • a tongue-shaped section 136 that can be deflected in a spring-elastic manner, which is also convexly curved in the same way as in the case of the contact element 14, counter to the direction in which it can be deflected, as in FIG 11 is clearly visible.
  • 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 runs in the foremost section of the contact element 13 at an angle to the longitudinal center axis of the contact element 13 and also at an angle to the path of the contact pin 9 when it is inserted into the insertion opening 2.
  • the central insertion opening 2 of the built-in connector can also be used to establish a plug connection with the contact pin 101 of a conventional jack plug - as in 3 shown - can be designed.
  • the contact element 13 is then in addition to the contact area with the shank of the contact pin 101 also provided with contact areas for the contact bulb 102 located at the free end of the contact pin 101 of the jack plug.
  • At least one first contact lug is preferably electrically connected to the contact element 14 protruding outwards into the insertion opening 3, from which the contact bulb 102 of the jack plug can be contacted, and a second contact lug is electrically connected to the contact element 13 protruding into the interior of the inner insertion opening 2 , From which the shaft of the contact element 101 of the jack plug can be contacted is provided.
  • a pushing element cooperating with the contact element 14 is advantageously present. In order to contact the contact element 14 with the contact pin 9 of the cable connector when it is plugged in, this is displaced from the ring-shaped plug extension in the direction of the central longitudinal axis of the housing 1 .
