Contact element for plug-in connector socket

摘要

To compensate the lateral offset of an opposing plug, a contact element for a plug-in connector socket has particularly large tolerances. For this purpose, the contact element is embodied in two pieces, a contact spring element for making electrical contact with the opposing plug and a securing element in which the contact spring element is mounted so as to be rotatable about a rotational axis. In contrast to a case in which tolerances depend on deformation of a spring element, by virtue of rotation of the contact spring element no forces act on the soldering points with which the securing element is soldered to a printed circuit board. The contact element is particularly suitable for soldering according to SMT.

1. A contact element for a plug-in connector socket, suitable for soldering to a printed circuit board, wherein the contact element comprises a contact spring element and a securing element, wherein the securing element has at least one soldered connection and wherein the contact spring element has two contact spring limbs for receiving and making electrical contact with a contact pin of an opposing plug, wherein the contact element is embodied in two pieces, wherein a first piece comprises the contact spring element and has opposed rotational arms about which the contact element is constrained to rotate, and wherein a second piece comprises the securing element, wherein the securing element has two side parts which lie opposite one another having opposed slotted apertures therein receiving respective opposed rotational arms, wherein the contact spring element is rotationally secured to the securing element such that the contact spring element is secured to and is mounted for rotation on said securing element, so as to be constrained to rotate at least through a limited angle about a rotational axis defined by said opposed rotational arms.
