Abstract
A connector block body of nonconductive material has a row of spaced open cavities. Within each cavity there is mounted an insulation displacement connector in the form of a metallic cylinder having a longitudinal slit. One wall of each of the cavities has a first slot extending from the cavity opening. The width of the first slot is slightly less than the diameter of the insulated wire for which the connector block is designed. A stuffer cap, which is attached to the block by a tether, has an open cavity. Mounted within the cavity of the cap is a post for engaging and forcing an insulated wire into the slit of the connector. Additionally, one wall of the cap has a slot and a cooperating nib which engage the wire and force it in the first slot wherein the wire is tightly grasped to prevent strain. In a second embodiment of the invention, a flat plate, bifurcated to define a restricted slit, is used as the connector. In lieu of the post, the cap in this embodiment has a ridge which engages the insulated wire forcing it into the slit of the plate.
