Abstract
A B S T R A C T - CANADA
The connector comprises a plastics housing having an open-topped cavity into which a terminal can be forced to terminate a wire inserted in the cavity through an aperture in the cavity wall. The terminal has spaced opposed plates joined at one end by a transverse web. A
wire receiving slot extends through the web into each plate.
A contact portion of the terminal extends through another aperture in another cavity wall. A lid closes the cavity to completely enclose the connection.
