Abstract

An electrical plug connector with an insulating body that holds at least one metallic plug part that comprises at least one solder connection element that can be soldered to a circuit board, and at least one plug connection element for a matching plug part, both of which are connected with each other via a central piece of the plug connection element. The solder connection element may be connected via a tolerance compensation part with the central piece of the plug part, or directly with the plug connection element, in such a way that, relative to the position of the solder connection element—with the solder connection element soldered to the circuit board—the position of the plug connection element can be changed in any direction, parallel to the plane of the circuit board. In addition, the invention relates to a plug connector assembly.

Claims

1. An electrical plug connector with an insulating body that holds at least one metallic plug part that comprises at least one solder connection element that can be soldered to a circuit board, and at least one plug connection element for a matching plug part, with the plug connection element extending in a longitudinal direction of the insulating body and perpendicular to the circuit board with at least the solder connection element projecting at least partially beyond the insulating body, wherein the plug connection element has the shape of a hollow cylinder with spring contact tabs and is connected with the solder connection element of the at least one plug part by means of a tolerance compensation part, arranged between the plug connection element and the solder connection element, in such a way that, relative to the position of the solder connection element—

with the solder connection element soldered to the circuit board—

the position of the plug connection element and/or the insulating body can be changed in any direction, parallel to the plane of the circuit board, with the tolerance compensation part deforming, and that the plug part may be composed of one or several pieces, wherein, if the plug part consists of a single piece, the tolerance compensation part is formed in a suitable place in the area of a central piece that connects the plug connection element and the solder connection element, and wherein, if the plug part is composed of two pieces, the tolerance compensation part is formed as an integral part of the solder connection element and is connected positively with the plug connection element, wherein the tolerance compensation part is arranged transversely in relation to the plug connection element and extends, in upright condition, radially to the plug connection element and parallel to the circuit board and in a straight line perpendicular to the plane of the circuit board and curved in the extension direction of the circuit board and having a S-shaped, U-shaped, circular, spiral-shaped or wave-like contour.

2. The plug connector according to claim 1, wherein the tolerance compensation part comprises an area with an S-shaped, U-shaped, circular, spiral-shaped, or wavelike contour.

3. The plug connector according to claim 1, wherein in case of a two-piece configuration of the plug part, the tolerance compensation part is welded to the plug connection element.

4. The plug connector according to claim 1, wherein that the tolerance compensation part with the solder connection element and the plug connection element consist of different materials.

5. The plug connector according to claim 4, wherein that the material of the tolerance compensation part is plastically deformable.

6. The plug connector according to claim 1, characterized in that at least the tolerance compensation part with the solder connection element formed thereon is a stamped bending part.

7. A plug connector assembly with at least two plug connectors according to claim 1 that are soldered to the circuit board.
