    • An impact tool for seating and cutting plural wires in a telephone wire termination block includes a movable cutter containing guide and shear elements having a spacial periodicity which differs slightly from that of terminals of the termination block. A force release mechanism in the tool handle includes a plunger translatable along the axis of the handle that engages a shaft for a stationary cutting head. The plunger passes through a bore of hammer which has a transverse bore sized to receive plural balls that are urged against and retain the plunger with the hammer. A main spring within the handle urges the hammer axially toward the shaft. The hammer passes through a ball-collar, which is axially translatable to remove retention between the hammer and the plunger, allowing the plunger to pass through the hammer bore, so that the hammer is rapidly axially translated by a main spring and strikes the plunger, imparting an impact force to the shaft. A force translation lever then linearly translates a movable cutter, which cuts the wires in rapid sequence.
    • 用于在电话线终端块中安置和切割多条电线的冲击工具包括可移动刀具,其包含导引件和剪切元件,其具有与终端块的端子稍微不同的空间周期性。 工具手柄中的力释放机构包括可沿着手柄的轴线平移的柱塞,其与用于固定切割头的轴接合。 柱塞通过锤的孔,该孔具有横向孔,其尺寸被设计成接纳多个球,所述多个球被推压并用锤保持柱塞。 手柄内的主弹簧将轴向轴向推动。 锤通过一个可以轴向平移的球形轴环,以消除锤和柱塞之间的保持力,允许柱塞通过锤孔,使得锤被主弹簧快速轴向平移并撞击柱塞, 向轴施加冲击力。 力平移杆然后线性平移可移动切割器,其可以快速地切割线。

    • A pistol-configured, electrically operated impact tool for seating and cutting a wire includes a D.C. motor whose output shaft has transversely extending, cam surface-engaging elements that engage a cam-configured impact element. As the output shaft is rotated by the operation of the D.C. motor, the cam surface-engaging elements are rotated to an angle where they begin to engage cam portions of the impact element. As a result of this engagement, the impact element is linearly translated away from the cutting tool holder and toward the electric motor. During this linear translation of the impact element away from the cutting tool holder, a bias spring is compressed, so as to increase the force stored in the spring. Eventually, the output shaft will be rotated to an angle brings the cam surface-engaging elements into alignment with a prescribed feature of the cam portions of the impact element. At this point, the compression spring is fully compressed and the force stored in the compression spring is released, thereby providing a prescribed wire seating and cutting impact stroke to the impact element. The impact element is rapidly propelled toward the cutting tool holder, so that the hammer strikes the cutting tool holder, whereby the wire seating and cutting tool attached to the tool holder seats and cuts one more wires in the terminal block.
    • 一种手枪式配置的电动冲击工具,用于支承和切割电线包括直流电动机,其输出轴具有横向延伸的凸轮表面接合元件,该凸轮表面接合元件接合凸轮构造的冲击元件。 当输出轴通过直流电动机的操作旋转时,凸轮表面接合元件旋转到它们开始接合冲击元件的凸轮部分的角度。 作为这种接合的结果,冲击元件从切割工具保持器和电动机线性地平移。 在冲击元件远离切割工具保持器的线性平移期间,偏压弹簧被压缩,以便增加存储在弹簧中的力。 最终,输出轴将旋转到一定角度,使得凸轮表面接合元件与冲击元件的凸轮部分的规定特征对准。 此时,压缩弹簧被完全压缩,并且存储在压缩弹簧中的力被释放,从而为冲击元件提供规定的线座和切割冲击行程。 冲击元件被快速地推向切割工具架,使得锤撞到切割工具保持器,由此连接到刀架的线座和切割工具座并且在端子块中切割另外一根线。

    • A wire-insertion and/or cutting tool comprises a handle having an axial bore, in which a wire-insertion and cutting blade assembly holder is installed. A wire-insertion and/or cutting blade assembly is inserted into the holder in a selected one of a plurality of blade assembly insertion orientations. The blade assembly includes a wire-insertion and/or cutting blade, that is configured to engage a wire to be inserted into a terminal block, and is operative to either seat, or to both seat and cut the wire in accordance with the selected blade assembly configuration and its insertion orientation. The blade assembly may include a rotatable cutting blade, and the holder configured to rotate the cutting blade and cut a wire engaged thereby for a first insertion orientation of the blade relative to the holder, but to prevent the cutting blade from rotating for a second insertion orientation of the blade assembly relative to the holder. The handle may also include a spring-loaded, axially translatable, impact hammer mechanism, that is selectively operative to impart an impact force to the holder, and thereby cause the blade assembly to seat/cut the wire.
