Abstract: Insulation displacement terminal member having cantilever spring contact members which are spaced-apart to receive a conductor between them. Each contact member has an outward projection for engagement with the wall of a cavity of a connector housing to prevent undue movement apart of the members when a heavily insulated conductor is forced between them under extremely cold conditions. Ideally, the projections are convex to permit a rolling action upon the cavity wall.

Abstract: Electrical connector with an insulation displacement member within an insulating body and a closure member for covering an insulation displacement terminal of the insulation displacement member. Two passages are provided into the closure member, one for guiding large diameter insulated wires to the position of the insulation displacement terminal and a second for smaller diameter wires. The second passage extends at an angle to the first passage and opens into the first passage close to the terminal position to produce a bend in the smaller diameter wire adjacent to the terminal position whereby the smaller diameter wire is stiffened at the terminal position.
