  • Patent number: 6948234
    Abstract: In a preferred embodiment, an end connector compression tool, including: a body; supports to support a cable and uncompressed end connector parts; a compression member axially movable with respect to the body to fixedly attach the end connector parts to the cable by compression of the end connector parts; a handle rotatably attached to the compression member at a first pivot point; and a link rotatably attached to the handle at a second pivot point and to the body at a third pivot point, such that rotation of the handle from an open position to a closed position effects compressive fixed attachment of the end connector parts to the cable. The tool may have an integral coaxial cable stripping function included therein.

  • Patent number: 5325587
    Abstract: In a preferred embodiment, a wire stripper, which includes: a generally elongate lower body member having first and second ends; a generally elongate upper clamping member having first and second ends and generally overlying the lower body member; an integral flexible hinge member joining the lower body member and the upper clamping member intermediate the respective first and second ends; an integral biaser disposed at and between the first ends, so as to bias the first ends apart by rotation of the upper clamping member around the flexible hinge member, and so as to draw the second ends toward each other, and to permit the second ends to be drawn apart by the further tensioning of the biaser by the rotation of the upper clamping member around the hinge member; and a cutting blade disposed in the second end of the lower body member along the major axis of the lower body member and extending above the upper surface thereof, such that a cable inserted between the second ends when the first ends are drawn toget

  • Patent number: 5105648
    Abstract: In a preferred embodiment, a handtool for crimping electrical connectors onto the ends of cables or similar operations, which handtool has major portions thereof constructed of a polymeric material. A metal structural insert is provided within the polymeric material to contain substantially all of the stresses developed by the crimping operations.

  • Patent number: 4985996
    Abstract: A wire stripper blade for cutting to the center conductor of a coaxial cable, the blade having a V-notch in the cirmcumferential periphery thereof. When the wire stripper is rotated about the cable, the corners of the V-notch cut through and sever the braid sheath and inner insulation layer of the cable, while the center conductor remains within a circle defined by the corners of the V-notch, which circle is spaced apart from and concentric with the center conductor. The use of a V-notch eliminates dragging of the braid and the possibility of one or more wire strands thereof wrapping around the center conductor. It also eliminates nicking of the center conductor which can cause poor transmission signals.

  • Patent number: 4932091
    Abstract: A tool for the attachment of a solderless, compression-fit end connector to the end of a coaxial cable, in which tool the components of the connector and the two-level stripped coaxial cable are positioned and then a manually lever-operated piston within the tool forces the components and the cable together, locking the connector to the cable and providing a sealed chamber in which the braid connection is made. In a preferred embodiment, the connector attachment mechanism is located at one end of the tool and a two-level coaxial cable stripper is located at the other end of the tool.

  • Patent number: 4805302
    Abstract: A wire stripper is provided with a body having mounted therein, in one preferred embodiment, one or more circular cutting blades, selectively positioned to sever one or more layers of an insulated cable. In a preferred embodiment, the body is compact and generally circular. The body has a cable accepting opening generally through its center into which the circular blades partially protrude. The blades are mounted on a slide reciprocatingly moveable back and forth within the body, which slide partially extends outward from the circumference of the body. When the extension of the slide is depressed toward the center of the body, the blades are withdrawn from the cable accepting opening and a cable may be inserted therethrough. The stripper is preferably manually rotated by gripping the outer circumference of the stripper and rotating it about the cable, thus inherently producing a circular cut.
