Abstract: A compressible sealing gasket for supporting a cable in a wall opening contained in a housing wall includes a pair of gasket sections each having a planar surface that contains a recess, and at least one integral compressible sealing projection extending from the planar surface adjacent the recess. When the gasket sections are placed in an assembled condition with their planar surfaces in contiguous engagement, the recesses cooperate to define a cable opening for receiving a cable, and the projection is compressed between the gasket sections to seal the space between the gasket sections adjacent the cable opening. Preferably two laterally spaced integral sealing ribs are provided in each recess, which sealing ribs extend transversely completely across the recess and terminate at each end in a sealing projection that extends upwardly from the associated planar surface.

Abstract: A connector system includes a plurality of conductor piercing units supported by a frame for vertical displacement between upper disconnected and lower connected positions relative to a plurality of parallel spaced insulated conductors supported in a horizontal plane by a base plate. The piercing units are displaced between said upper and lower positions by operating disks eccentrically mounted for rotation on a horizontal support shaft that extends between an opposed pair of side walls of the frame. The base plate, frame and piercing unit assembly are arranged in an open-topped support housing that is closed by a cover member or lid. Electrical components may by mounted on the lid for connection with the piercing unit assembly.

Abstract: An electrical connector arrangement taps off electrical current from a plurality of coplanar parallel input insulated conductors and supplies the same to a plurality of output conductors, respectively. A rectangular base member is provided having a horizontal upper surface that supports a plurality of parallel coplanar longitudinally-extending input conductors, respectively. A pair of pivot members are connected with the ends of the base member for pivotal movement about transverse horizontal pivot axes, respectively. As the pivot members are pivoted from disengaged positions toward engaged positions parallel with and directly above the base member top surface, bifurcated insulation-piercing knives on the pivot members pierce the insulation layers of the insulated conductors and electrically engage the conductors.
