The invention relates to a socket contact, consisting of a contact sleeve, the flexible contact elements of which rest on a plug contact inserted into the socket contact, as well as a concentric one to the sleeve arranged guide body, whose ring-shaped closed end part forms the insertion opening of the socket contact.

In a known socket contact, the sleeve-shaped contact body is slotted so that tongues arise, which are intended to make contact with a plug contact resilient contact elements form. It has proven to be disadvantageous in this embodiment that the resilient contact elements when inserting a pin of too large a diameter bent outwards and thus are expanded, making the socket contact unusable due to a lack of sufficient contact pressure will.

In order to avoid this disadvantage, a two-part socket contact has also been developed, consisting from a contact sleeve provided with resilient contact elements and a concentric one to this sleeve arranged guide body, the ring-shaped closed end part of the inlet opening of the socket contact. In this design, the guide body is in the interior of the contact sleeve arranged, the contact elements from the outside to the inside by a provided in the guide body Reach through the breakthrough.

In this known embodiment, the insertion of a pin that is too large into the Socket contact excluded. Damage to the resilient contact elements, however, is thereby possible that inadvertently a thin connector pin is inserted obliquely into the guide body, whereby the spring elements are bent outwards.

In order to eliminate the disadvantages of the "open" socket contacts mentioned at the beginning, One-piece socket contacts have already been developed in which the end on the steek pin-side is closed in a ring is. The disadvantage of these designs, however, is that they are technical in terms of production are relatively complicated and their assembly is difficult.

The invention is therefore based on the object while avoiding the shortcomings of the known designs a socket contact of the type mentioned with an annularly closed insertion opening to develop in which damage to the resilient contact elements is definitely excluded is.

This object is achieved according to the invention in that the guide body consists of several Tongue-shaped contact elements enclosing the existing front part of the contact sleeve on the outside and has breakthroughs through which locking projections provided on the contact elements are exposed reach through.

In the embodiment according to the invention, the guide body is more annularly closed End part forms the insertion opening of the socket contact, thus attached over the resilient contact tongues, which ensures that these tongues even with careless handling of the socket

contact, especially if a thin connector pin is accidentally inserted at an angle, not bent open can be.

In terms of assembly technology, it is advantageous according to one embodiment of the invention if the con-

clock sleeve is releasably fixed by means of the locking projections in an insulating material socket. That way lets the socket conitact can be fixed in the insulating material socket with a single movement or for repair purposes loosen from the socket.

Details of the invention can be found in the description of an exemplary embodiment illustrated in the drawing emerged. It shows

For this purpose, a sleeve-set guide body 12 is pushed into the tool, which is shaped like an insulating material, onto the latching projections 22 -32. The bore of the insulating material socket is pushed so that it has a part 44 that is narrowed in diameter in the radial direction towards 32 and is pressed inside.
