  • Publication number: 20090293984
    Abstract: This invention relates to a hand tool capable of clipping wires of different diameters. The hand tool of the present invention comprises a main body, at least one first clipping piece, at least one second clipping piece, and at least one elastic element. The at least one first clipping piece is pivoted to the main body, and the at least one first clipping piece forms a first clipping area. The at least one second clipping piece, which is stacked next to the at least one first clipping piece, is pivoted to the main body, and the at least one second clipping piece forms a second clipping area that is different from the first clipping area. The at least one elastic element provides clipping force to the at least one first clipping piece. By the above structure, a wire can be clipped at the first clipping area or at the second clipping area.

  • Publication number: 20060032048
    Abstract: The press-connecting head comprises three elements including a pressing rod, a die core and a rotation cap; wherein the pressing rod is provided on the press-connecting head at a position in corresponding to a fixed die block of the press-connecting head, and has centrally thereof an axial hole for receiving the die core; the rotation cap is slipped over the front end of the pressing rod and is rotatable relative to the pressing rod, and has on the inner side thereof a thread to engage with the front end of the die core; when the rotation cap is rotated, the die core displaces and protrudes from the front end of the pressing rod or is hidden in the rotation cap. When in use, the pressing rod is displaced relative to the die block to press connect a coaxial terminal with a coaxial wire; by displacement and adjustment of the die block, the pliers can suit coaxial terminals of different specifications.

  • Patent number: 6968726
    Abstract: The pair of press-connecting pliers for pins on electric communication terminals are provided on the front and rear sides of thereof with three kinds of press-connecting grooves. One of the two sides is formed thereon a first press-connecting groove and a second press-connecting groove, while the other side is formed thereon a third press-connecting groove in opposition to the second press-connecting groove; so that the left and right sides of the press-connecting pliers are formed thereon two terminal holding seats respectively from the first press-connecting groove, the second press-connecting groove and the third press-connecting groove, thereby the two terminal holding seats at least can simultaneously do press connecting for pins on electric communication wires and electric communication terminals of three different types, this simplifies the size of the entire press-connecting pliers.

  • Publication number: 20050258837
    Abstract: The press-connecting pliers mainly comprises a main body, a testing unit and an electric power supplying unit; the main body at least has a press-connecting slot for press connecting of an electric communication terminal and a transmitting line; the testing unit is provided in the main body and comprises an electric circuit board, a testing insertion groove and an indicating unit for the purpose of examining whether the communication terminal is electrically connected after press connecting, and using the electric power supplying unit to supply electric power required by the testing unit. Thereby, after press connecting of the electric communication terminal using the press-connecting slot, it is convenient to examine whether the communication terminal is electrically connected after press connecting directly through the testing unit.

  • Publication number: 20030177587
    Abstract: A pair of multifunctional peeling pliers of which a pair of mutually confronting cutting blades are provided on the handles of the pliers, the pliers are provided with a plurality of peeling knives and wire receiving recesses having suitable spaces respectively from the cutting blades of the handles; and a spring is provided between the handles of the pliers. Thereby, the whole pliers can be used to cut wires by means of the cutting blades and to practice peeling of a coating layer of a wire taking advantage of the section on one of the handles having the peeling knives and wire receiving recesses. And when the pliers are not in use, the handles of the pliers can be in the closing state normally by the action of the spring to avoid exposure of blades of the cutting knife and the peeling knives and to increase safety of the entire pliers.
