Abstract: A pliers-type gripping tool includes a pair of gripping jaws, a pair of pivotally connected hand grip levers for operating the gripping jaws between an open separated condition and a closed gripping condition, and an adjusting device for varying one of the physical operating properties of the tool. In one embodiment, the hand grip levers are sectional, and the adjusting device includes an angle setting arrangement for determining the angular relationship of the sections, thereby to permit use of the tool to engage an object at a relatively inaccessible location. In a second embodiment, at least one of the levers includes a metal lever body member partially enclosed by a synthetic plastic shell member. An adjusting device controls the lateral relative positions of the lever body and shell members to adjust the effective thickness of the hand grips to correspond with the size of the hand of the user.

Abstract: An insulation stripping tool of the pliers-type includes an adjustable pull rod stop device for limiting the extent of travel of the longitudinally displaceable pull rod and the cutting and stripping blades connected thereto, thereby to produce only partial removal of a length of severed insulation layer from an insulated conductor. An adjustable conductor stop device is mounted on at least one of the cutting and stripping blade holders for limiting the extent to which the end of the insulated conductor is inserted into the open mouth of the stripping tool. A stationary scale is mounted on one of the handles adjacent the adjustable conductor stop device.

Abstract: A pliers-type insulation stripping tool includes a releasable fastening device for fastening a knife cassette to at least one of the knife carrier members that are longitudinally displaced by the pivotally connected tool handle members to remove a severed length of insulation from a longitudinally-arranged insulated conductor that is clamped between by the tool gripping jaws. A U-shaped resilient fastener spring wire has leg portions that are resiliently biased apart, at least one of the legs containing a laterally extending bulge portion that extends into a corresponding locking slot contained in a side wall of the knife cassette. To release and replace the knife cassette, the protruding free extremities of the leg portions of the spring wire are displaced together, thereby to remove the leg bulge portion from the slot contained in the cassette outer wall.

Abstract: A pliers-type insulation stripping tool includes an adjusting device for adjusting the cutting profile provided by the knife edges of a stack of parallel lamellar cutting blades pivotally connected at one end with a knife holder for independent pivotal movement about a first pivot axis parallel with the tool handle pivot axis. The knife holder is connected for longitudinal displacement on one the clamping jaws of the tool handles, thereby to remove a severed length of the insulation layer from the insulated conductor.

Abstract: A pliers-type insulation stripping tool includes a pair of blade holders that are removably connected with the pull rod that longitudinally displaces the blades relative to the handle shell when a severed length of insulation is stripped from the insulated conductor. A resilient ejector arrangement in provided for ejecting from the handle shell the length of stripped insulation. In order to permit use of the insulation stripping tool with insulated conductors of various sizes and diameters, a blade depth adjusting device is provided for adjusting the distance between at least one of the blade holders and the associated clamping jaw.

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: An insulation stripping tool for flat cables includes a clamping device adapted to be clamped to a flat cable and to provide a linear guide edge for guiding a knife holder to accurately sever the outer insulation sheath of the cable in a transverse direction. Upon removal of the clamping device from the cable, the knife holder is inserted into a chamber contained in the clamping device with the knife edge protruding from the chamber, whereupon a curved side of the flat cable is inserted within first guide grooves contained in the clamping device, and the clamping device is displaced circumferentially of the cable to sever the curved cable side transversely of the cable. The curved cable side is then inserted into a second pair of grooves contained in the clamping device, and the knife holder is displaced longitudinally to sever the insulation sheath longitudinally of the cable.

Abstract: A pliers-type insulation stripping tool includes an adjusting device for adjusting the cutting profile provided by the knife edges of a stack of parallel lamellar cutting blades pivotally connected at one end with a knife holder for independent pivotal movement about a first pivot axis parallel with the tool handle pivot axis. The adjusting device comprises a cylindrical support member that is mounted in the associated knife holder for rotation about an axis parallel with the first pivot axis. The circumferential surface of the support cylinder includes a plurality of segments that are selectively engaged by flat portions of the cutting blades, thereby to define different cutting profiles, respectively. The knife holder is connected for longitudinal displacement on one the clamping jaws of the tool handles, thereby to remove a severed length of the insulation layer from the insulated conductor.

Abstract: An accessory for pliers-type tools includes a shell that is removably connected with one or both levers of the tool to alter the size of the gripping portion of the tool to conform with the size of the user's hand. Each shell has a generally L-shaped configuration and an outer gripping surface which is arched, preferably in both longitudinal and latitudinal directions, to accommodate the user's hand. In addition, the levers include an opening adjacent to the gripping portion and the shells include a locking mechanism adapted to engage the lever within the opening to connect the shell with the lever.

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.
