Abstract
The configuration makes electrical contact with an electric valve, in particular a shift or pressure regulating valve for automatic transmissions of motor vehicles. The configuration is equipped with a contact spring element arranged outside a valve housing of the electric valve. In the assembled state, the contact spring element acts on an exposed opposing contact element of a wiring element under spring pressure. For this purpose, the contact spring element has a pressing section with a rounded bearing surface and the mutual contact surfaces on the spring element and on the wiring element are tinned.
Claims9
A configuration for making electrical contact with an electric valve, comprising:
- at least one contact spring element having an S-shaped section disposed outside a valve housing of the electric valve;
- said contact spring element having an arcuate-shaped pressing section with a tinned, rounded bearing surface;
- and
- a flexible printed circuit board for making electrical contact with the electric valve, said flexible printed circuit board having an opposing contact element with a tinned opposing bearing surface;
- in an assembled state, said tinned, rounded bearing surface of said contact spring element bearing against said tinned opposing bearing surface of said printed circuit board under spring pressure for making secure electrical and mechanical contact with said flexible printed circuit board.
