Electrical connector apparatus

摘要

The present invention is directed to apparatus for maintaining good conductivity characteristics over time between a spring connector in contact with a connector housing having a plated substrate material. An insert is fitted into an appropriate space in the cast housing. The insert forms a gas tight seal with the housing at appropriate edges. The seal prevents oxidation of plating materials along the edges thereby maintaining good conductivity characteristics over time between the cast housing and the insert. The spring conductor and the insert are made from or plated with materials which do not form an oxide layer and thus maintain low contact resistance over time, thereby preserving good conductivity characteristics of the entire electrical path over time.
