ABSTRACT:
Connecting means comprises an electrical terminal and a housing having a terminal-receiving cavity therein. The terminal is a flat one-piece sheet metal device having two integral four-bar linkage mechanisms thereon arranged symmetrically with respect to an axis extending medially through the terminal. The connecting or floating links of the linkages are adjacent to the axis, the fixed links are relatively remote from the axis, and the crank links extend diagonally between the fixed and connecting links. When a wire is positioned between the connecting links and the two four-bar linkages are deformed by applying deforming forces to the ends of the connecting links, the connecting links move laterally towards each other and clamp the wire between their opposed surfaces. The cavity in the housing has wire-admitting slots which permit placement of the wire with its axis extending transversely across the cavity and a shoulder is provided adjacent to the inner end of the cavity which is engageable with the ends of the connecting links when the terminal is inserted. The arrangement is such that upon placement of the wire in the cavity and insertion of the terminal, the four-bar linkages are deformed and contact is established with the wire.
