Use of an axial canted coil spring as an electrical contact to minimize resistivity variations under dynamic loads

摘要

A medically implantable electrical connector includes a housing having a bore with an internal groove therein along with a pin sized for insertion into the housing bore. A film removing spring is disposed in the housing groove dynamic loading of the spring in the groove by the pin causing scraping of film from the groove and pin surfaces to provide lowered electrical resistance therebetween.
