Abstract

An electrical connector for being electrically coupled to at least one electrical conductor. The connector includes a housing and at least one contact positioned therein and including a tip portion which protrudes from the housing to engage the conductor. Significantly, the contact, initially of a non-stressed configuration, is preloaded within the housing to assume a curved configuration and to engage the respective conductor in such a manner that sound, positive engagement occurs in a substantially non-wiping manner. The housing may thus be stationarily positioned relative to the circuit member, the circuit member able to thus press against the tip portion of the contact to complete coupling. The remaining part of the invention may be electrically coupled to an external conductor, e.g., a cable.

Dependent claims

An electrical connector for being electrically coupled to at least one electrical conductor, said connector comprising:

a housing defining a chamber therein;
at least one electrical contact positioned within said housing and including a tip portion protruding from said housing and adapted for engaging said electrical conductor with a predetermined force and an opposing end portion securely positioned within said housing, said contact having an initial overall first length and corresponding first width prior to being positioned within said housing, said housing engaging said contact at three spaced locations on said contact so as to preload said contact within said housing such that said contact will possess a second length and corresponding second width, said second width greater than said first width and of an established, relatively small percentage of said overall first length, said housing being disengaged from said contact at one of said three spaced locations when said tip portion engages said electrical conductor to thereby substantially prevent a sliding type of engagement between said tip portion and said conductor.
