Socket contact

Abstract

A socket contact (1) has a hollow cylindrical contact wire region (AB) for receiving a stripped end portion of an electrical conductor to be connected, and a hollow cylindrical contact region (KB) with a pin insertion opening (2) for receiving a contact pin. The contact region (KB) has a cylinder wall with at least one radially inwardly folded contact blade (4), the free end of which points towards the pin insertion opening (2). The cylinder wall has an at least partially circumferential groove (5) for the contact blade in the region of the fold.

Claims

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0019] An exemplary embodiment of the invention is illustrated in the drawings and will be explained in more detail hereunder. In the drawings:

[0020] FIG. 1 shows a lateral view of a socket contact; and

[0021] FIG. 2 shows a sectional illustration of the socket contact.

DETAILED DESCRIPTION

[0022] The figures to some extent contain simplified schematic illustrations. To some extent, identical reference signs are used for the same but potentially not identical elements. Different views of identical elements may be to different scales.

[0023] The socket contact 1 is produced, in particular by subtractive operating steps, from a solid piece of wire.

[0024] FIG. 1 shows a socket contact 1. The socket contact 1 proximal to the connector has a hollow-cylindrical connector region AB for receiving a stripped end region of an electric conductor to be connected (not shown). The connector region AB is configured as a crimp connector.

[0025] Proximal to the plug the socket contact 1 has a hollow-cylindrical contact region KB having a pin introduction opening 2 for receiving a matching contact pin (not shown for illustrative reasons). The connector region AB and the contact region KB are connected to one another by way of a solid web 3.

[0026] The contact region KB has a cylinder wall having a contact blade 4 which is folded radially inward. The contact blade 4 by way of the free end thereof points toward the pin introduction opening 2. The cylinder wall of the contact region KB in the root region, i.e. where the contact blade is bent radially inward, has an encircling groove 5.

[0027] The center of this groove can also lie so as to be eccentric in relation to the center of the hollow cylinder of the socket contact. As a result, a groove which is not visible in an encircling manner can also be created.

[0028] The contact region KB has an insertion depth T for the contact pin. The contact blade 4 has a length l. The length l is between 40% and 95% of the insertion depth T. This means that the ratio of l/T is between 0.4 and 0.95.

[0029] A slot which is inclined by approximately 45° in relation to the plug-in direction is incorporated in the cylinder wall of the contact region KB. As a result, the free end of the contact blade 4 is of an oblique design.

[0030] Even though various aspects or features of the invention are respectively shown in combination in the figures, it is clear to a person skilled in the art that—unless otherwise stated—the combinations shown and discussed are not the only ones possible. In particular, mutually corresponding units or complexes of features from different exemplary embodiments can be exchanged with one another.
