Problems solved by technology

If such a socket contact is made of solid material (for example from a wire with a corresponding diameter), it may occur that the contact tongues break at the root due to the bending process
Furthermore, such socket contacts exhibit fluctuations in the event of so-called pull-out forces, in which the contact pin is pulled out of the contact socket
Therefore, the pull-out force is always set to the upper tolerance limit, which results in an overall high pull-out force

Embodiment Construction

[0026] The socket contact 1 according to the invention is produced in particular by machining from a solid wire.

[0027] figure 1 A socket contact 1 according to the invention is shown. The socket contact 1 has, on the connection side, a hollow-cylindrical connection area AB for accommodating the stripped end regions of the electrical conductors (not shown) to be connected. The connection area AB is designed as a crimp connection.

[0028] The socket contact 1 has, on the insertion side, a hollow-cylindrical contact area KB with pin insertion openings 2 for receiving mating contact pins (not shown for illustrative reasons). The connection area AB and the contact area KB are connected to each other by solid webs 3 .

[0029] The contact zone KB has a cylindrical wall with radially inwardly folded contact tongues 4 . The contact tongue 4 points with its free end towards the pin insertion opening 2 . The barrel wall of the contact zone KB has a circumferential groove 5 in t...

Abstract

The invention relates to a socket contact (1) having a hollow cylindrical connection region (AB) for receiving a stripped end region of an electrical conductor to be connected, and having a hollow cylindrical contact region (KB) having a pin insertion opening (2) for receiving a contact pin, the contact region (KB) having a cylindrical wall, the cylinder wall has at least one contact tongue which is folded radially inwards and the free end of which points to the pin insertion opening (2), and wherein the cylinder wall has an at least partially circumferential groove (5) in the folding region for the contact tongue.

Description

technical field [0001] The invention relates to a socket contact of the type according to independent claim 1 . [0002] Such socket contacts are used in plug connectors to transmit current, signals and / or data. Background technique [0003] DE 1 640 554 A1 shows a socket contact made of flat spring steel sheet by means of punch-bending technology. The contact areas of the socket contacts have contact tongues that are folded radially inward multiple times. [0004] The spring steel sheet used can be easily machined. However, the current-carrying capacity of socket contacts made of this material is not always sufficient. [0005] Receptacle contacts made of solid material provide better electrical performance here. If such socket contacts are made of solid material, for example of a wire having a corresponding diameter, it may happen that the contact tongues break at the root due to the bending process. Furthermore, such socket contacts exhibit fluctuations in the presen...
