Abstract
The disclosed connector has a housing and a terminal interfitted in a channel in the housing, and special exposed jaws are formed on the terminal between which a wire of the type having a conductive core and an insulation overwrap can be forced to establish a mechanically secure and an electrically sound solderless type connection. One pair of jaws are rigid and have cutting and gripping edges that cut through the insulation overwrap to establish electrical contact with the conductive core. These same edges are used to axially restrain the wire relative to the terminal. The second pair of jaws are flexible and have inwardly sloped tabs presenting adjacent edges that are angled transversely of the wire and are spaced apart approximately by the diameter of the insulation overwrap. The wire thus can be forced past the tabs spreading apart the second set of jaws which then spring back and overlie the wire and thereby transversely restrain the wire relative to the terminal.
