Electric contact element and casing for receiving such a contact

摘要

The electrical contact unit fits into an electrical circuit hole and has a good electrical contact body (1) with an electrical conductor fixture (2,4). The body has a section (15) to attach a spring in the body extended by tonguelets (20,28) with a free end contact part (21, 29) contacting the circuit and having an attached ring (27). The spring has sections (34,35) tending to push the outer contact tonguelets apart.
