  • Publication number: 20030015072
    Abstract: Gripping pliers having upper and lower jaws facing each other. An upper handle supports a bearing member extending through first and second walls of the upper handle. A supporting member connected to the lower jaw extends through the upper handle, and is supported to the upper handle via a bearing member which is free to rotate. A threaded ring within the bearing member adjusts the length of the supporting member, thereby establishing a distance between the gripping jaws of the pliers. A relatively constant facing relationship between upper and lower jaws is maintained through the geometry created by the location of the bearing axis relative to the distance between the pivot point of the lower jaw and a pivot formed by the end of the toggle link.

  • Patent number: 5040288
    Abstract: A tool for crimping a connector onto a cable includes a crimping device which is mounted on a forward end of an axially movable piston, and a localizing device for detachably holding a cable and a connector in position for coaction with the crimping device while crimping the connector onto the cable. The piston is journalled in a hollow spindle and is driven reciprocatingly at a pre-determined length of stroke by means of a drive mechanism. The tool further has a distance setting means, including an external screw thread on the spindle and a nut surrounding the spindle and engaging the screw thread thereof, for continuous setting of the distance between the crimping device, when the piston is located in its retracted position, and the localizing device.

  • Patent number: 5012666
    Abstract: A crimp tool includes a first handle, a head member pivoted to the front portion of the first handle to serve as a clamping member, and a second handle pivoted to the head member. The second handle is connected to the first handle through a mechanism which urges the second handle and the head member to the releasing position thereof. An adjustment member for the jaws of the crimp tool includes an adjustment screw rod and two nuts to adjust the position of a pivot pin in an oblong pivot hole which pivots the head member to the first handle member so that conductors of different cross-sections can be crimped effectively.
