The invention relates to a stripping tool, in particular stripping pliers. The stripping tool is here used for a multi-wired cable. According to the invention two pairs of stripping blades are used in the stripping tool. The two pairs of stripping blades are moved in preferably parallel planes (60, 61) besides one another. According to the invention it is possible to simultaneously strip the insulations of e.g. four conductors of a four-wired cable.

A fiber optic stripping apparatus comprising a frame having an axis and a pair of outer arms extending from the axis, each arm pivotal about the axis and a pair of first blades each first blade having a first blade edge, each of the first blades attached to a corresponding frame arm with the first blade edge extending in the direction of the corresponding frame arm. The stripping apparatus includes a pair of second blades each second blade having a second blade edge, each of the second blades attached to a corresponding frame arm with the second blade edge extending transverse to the direction of the corresponding frame arm, the second blades each having a first set of notches forming a circle when the stripping apparatus is in a closed position and a second set of notches substantially forming a circle when the stripping apparatus is in the closed position.

An electric screwdriver includes a motor having a motor shaft, a handle housing for accommodating the motor, an output shaft at least partly protruding from the handle housing, a transmission device for enabling the motor shaft to drive the output shaft to rotate around a first axis, an exploring antenna for detecting whether an object is charged, an operating switch coupled to the handle housing for controlling the motor, a first wire stripping member fixedly mounted to the handle housing; and a second wire stripping member rotatably connected to the handle housing.

While stripping an electrical cable in a stripping device of a cable-processing system, detection by an electrically conductive cutting device with a sensor circuit takes place if contact with a conductor occurs. By connecting the sensor circuit to the cutting device a measuring capacitance is developed. Before incising the electrical cable, a capacitance value of the measurement capacitance is determined during a first measurement cycle in which a charge equalization is carried out between the measurement capacitance and a reference capacitance. A parameter is determined in a further measurement cycle in which a charge equalization is again carried out between the measurement capacitance and the reference capacitance, wherein, relative to the first capacitance, the parameter displays a change in the capacitance after incising into the electrical cable. A signal is produced, if the change is greater than an established threshold value, indicating contact with the conductor.

A cable-shaving tool for midspan shaving of a cable jacket includes a housing bottom having a first hinge member along an upper edge, a cavity, and at least one cable groove extending through a length of the housing bottom. The cable-shaving tool includes a second housing shell having an interior portion having at least one recess having an upper control surface, an exterior portion, and a second hinge member along a second housing shell edge engageable with the first hinge member wherein the second housing shell is rotatable about the first hinge member. The cable-shaving tool includes a blade removably securable between a blade holder and a blade support surface on the housing lid, the blade extending within a portion of the recess and a movable cable ramp disposed in the cavity of the bottom housing for urging the cable toward the blade when the second housing shell is in a closed position.

A multi-purpose electrical tool is described herein for electrical wiring manipulations. The multi-purpose electrical tool combines the functions of several different tools, for example gripping, bending, cutting, stripping, and curling, and the like, into a single tool. The multi-purpose electrical tool comprises two body members attached at a pivot point and two jaws portions. The jaw portions move open and closed when the body members are opened and closed, facilitating cutting functions. The jaw portions also allow for wire curling. One of the body members includes a slot for inserting a screwdriver into the slide for its immediate use.

A coating removing device includes a main body that includes a blade used for coating removal; a gripping section that grips an optical fiber; and a slider that connects the main body and the gripping section together so as to be able to approach or separate from each other. The coating removing device removes a coating from the optical fiber by separating the main body and the gripping section after an incision has been made in the coating of the optical fiber using the blade. The slider includes a retention unit to retain the main body and the gripping section in a maximum separation state.

A coating removing device includes a heating section that includes a heater to heat a coating of an optical fiber, and a blade to make an incision in the coating of the optical fiber; a gripping section that grips the optical fiber and is capable of moving with respect to the heating section; and a counter that counts a coating removal event number by detecting separation between the heating section and the gripping section.

A perforation apparatus for use with cable jackets and related systems and methods thereof is provided. The tool includes a pliers assembly having at least a first jaw member positioned opposing a second jaw member, wherein relative movement of the first and second jaw members is controlled with at least a first handle and a second handle. A first knife edge is on the first jaw member and a second knife edge is on the second jaw member. Each of the first and second knife edges are oriented substantially parallel to one another and substantially perpendicular to a length of first and second handles. The first and second knife edges are movable towards one another. A spacing device is connected to the pliers assembly, wherein the spacing device controls a closing distance between the first knife edge and the second knife edge.
