Coupling arrangement for revs transmitter e.g. coupled to automobile chassis

摘要

The coupling arrangement provides a contact between the electric connections of a sensor, particularly a revs. counting sensor, and a cable which transfers output signals to a processing circuit. The arrangement (35) comprises a basis (32) firmly joined with the sensor (1) and a coupling element (60,60'), which is joined with the basis (32) in an assembled condition so that it is rotatable around an axis. A separable transformer (42,48,52,58) is provided with at least a pair of ring-shaped spools (48,58), of which the one (48) is arranged static at the basis (32) and concentrically to the axis, and the other (58) is revolving and connected with the cable (66) leading to the exterior. In the assembled condition a sufficient magnetic coupling for signal transfer is provided between both spools (48,58).
