Abstract
The invention relates to an electrical plug connector including a plug and a coupling in which radially spring elastic annular contact lamellas are arranged. In order to prevent corrosion when the plug and the coupling are made from different materials the invention proposes a tin plated bushing in the coupling in which bushing the contact lamellas are arranged.
Claims8
An electrical plug connector, comprising:
- a pin shaped plug;
- a sleeve shaped coupling enveloping the plug with a gap in an inserted condition;
- and
- at least one electrically conductive contact element arranged in the gap and configured as a ring,
- wherein the at least one electrically conductive contact element is spring elastic transversal to a plug-in direction and contacts the plug in the inserted condition and electrically connects the plug and the coupling,
- wherein the plug and the coupling are made from different metals,
- wherein a bushing made from metal is arranged between the coupling and the contact element, and
- wherein the at least one electrically conductive contact element contacts the bushing which is in electrically conductive contact with the coupling and which includes a corrosion protection layer.
