Abstract
Abstract An environmentally sealed terminal block includes a hollow block member and a plurality of connection assemblies mountable on the block member for providing interconnections between respective conductors of two groups of wires. Each of the connection assemblies includes an insulation displacement connector for receiving at least one conductor of each of the two groups of wires, a cap mountable to the block for accepting a quantity of sealing material for surroundingly engaging and environmentally sealing the insulation displacement connector and having a through aperture. A conductive activating screw extends through the through aperture and has a head portion projecting outwardly of the cap when assembled therewith to provide a test point. A nonconductive head cap member surroundingly engages the head of the activating screw and has an opening for access to the test point, the head cap member engaging the cap member for coupling the screw therewith, and the screw being freely rotatable relative to the head cap member and to the cap member. A conductive plate electrically interconnects the activating screw and the insulation displacement connector; and a resealable cap seal is coupled with the nonconductive head cap member for covering the opening therein, and is selectively openable and reclosable for permitting selective access to the test point.
