Electrical plug type connector having a microstructured contact element
View Patent ↗In an electrical plug type connector having an electrically conductive contact element having a contact surface, the contact surface has a microstructure.
1. An electrical plug type connector having an electrically conductive contact element having a base material and a coating positioned on the base material, the coating defining a contact surface of the contact element, wherein the contact surface is comprised of an electrically conductive material having a microstructure forming an at least partially periodic structure, the microstructure having a scale-like structure defining the at least partially periodic structure, and wherein the scale-like structure includes a plurality of three-dimensional scales, and each of the scales overlaps an adjacent scale.
2. An electrical plug type connector according to claim 1 , the contact surface having tin or silver or an alloy of tin or silver.
3. An electrical plug type connector according to claim 2 , the contact element comprises copper or a copper alloy and being tin-coated or silver-coated or coated with a tin/silver alloy.
4. An electrical plug type connector according to claim 1 , the contact surface having projections and recesses.
5. An electrical plug type connector according to claim 4 , a lubricant being arranged in at least one recess.
6. An electrical plug type connector according to claim 1 , the periodic structure in at least one direction having a periodic length in the range between 1 μm and 100 μm.
7. An electrical plug type connector according to claim 1 , the microstructure being produced by means of a laser or electron beam processing operation of the contact surface.
8. An electrical plug type connector according to claim 1 , the contact element being a contact pin.
9. An electrical plug type connector according to claim 1 , the contact element being a contact spring.
10. An electrical plug type connector according to claim 1 , the plug type connector having a plurality of contact elements.
11. An electrical plug type connector according to claim 1 wherein each of the scales has a circular shape.
12. An electrical plug type connector according to claim 1 , wherein a projection is defined between overlapped portions of adjacent scales.
