Abstract
Abstract An electrical connector system includes socket and plug connector components which each receive a plurality of electrical wires for interconnection. The socket and plug components each include a molded receiver element having a plurality of elongated, parallel locking finger elements and a molded spacer element having a plurality of elongated, parallel spacer fingers. The receiver and spacer elements are assembled so that their respective fingers are interdigitated to define a plurality of terminal receiver channels within each of the socket and plug components. Each of the electrical wires carries a socket or a pin terminal for connection to respective socket or plug components, the terminals each incorporating a locking surface which engages a corresponding locking surface formed in corresponding terminal receiver channels, so that the terminals can be releasably secured in the connector components.
