Abstract
Abstract Polymeric electrically conductive apparatus such as electric connectors are disclosed. These connectors employ a polymeric conductive material such as a conductive epoxy having conductive particles dispersed therein sufficient to establish electrical conductivity. These conductive materials are at least initially deformable such that electrical conductors may be inserted within an envelope containing the conductive material and electrical continuity for a prescribed circuit can be verified before structurally affixing the conductors to the envelope. Embodiments having radially collapsible envelopes for forming splice connectors and multicontact configurations employing rigid dielectric housings are disclosed.
