A wire stripper for stripping cables has two plier jaws, two outer clamping jaws, two inner cutting jaws, and two gripping parts. The cutting jaws can be displaced from a starting position into an end position by a pull rod while pressing together the gripping parts. The cutting jaws are guided on sliding block parts that rest against a sliding block fixed in the clamping jaws. The cutting jaws are moved toward each other to varying degrees through these sliding block parts, depending on a closed position of the clamping jaws, with the closed position determining the movement of the sliding block part. The sliding block parts can be manually adjusted independently of a closed position of the clamping jaws in terms of a position relative to the sliding block, while at the same time acting on both sliding block parts.

Stripping pliers have two outer clamping jaws, two inner cutting jaws and two handle parts, wherein, in the course of pressing together the handle parts, the cutting jaws can be displaced from a starting position into an end position by a pull rod against the force of a spring acting on the pull rod. The pull rod is traversed by a pull pin which can move in a slot. In order to configure the stripping pliers such that they are further improved in a manner which is advantageous for handling, the pull rod has, at its handle-side end, a displacement part which is fastened to the pull rod and which is displaceable against the force of the spring relative to the pull rod, to free the pull rod from a handle-side mounting.

Gripper jaws for an insulation stripper have a gripping surface and an attachment extension with ribs which run transversely to a longitudinal direction of a cable to be gripped when the gripping surfaces are fitted, and have groove-like recesses corresponding to the ribs and running between the latter. When the gripper jaws are fitted, the ribs can enter into the recesses of the opposing gripper jaw in accordance with the thickness of the cable to be gripped. Blades for an insulation stripper have, on their free ends that run into a blade tip with an acute angle in cross-section, a contour line which has a depression, when seen from a side view in which the contour line forms the termination line of the blade.

A crimping tool has crimping dies arranged in a star shape directed at a crimping region and subjected to rotational action radially outwards for the crimping movement by means of an actuating part. The crimping dies are mounted about an axis of rotation transversely to the longitudinal extent thereof for pivoting-in and form an abutment region on the crimping region side of the axis of rotation. A radial movement and/or circumferential movement is brought about to coincide with the rotational action on the crimping dies, in order to obtain abutment of a crimping die in the abutment region thereof against the counter-abutment region of another crimping die adjacent to the crimping die in the pivoting direction or counter-pivoting direction.

Crimping tool

The invention relates to a crimping tool () having crimp indentors and a through-opening for the introduction of a cable end which is to be crimped, introduction of the cable end being limited by an adjustable stop part () which is fixedly connected to the crimping tool (), but is preferably operationally releasable, furthermore, the stop part () having different stop pins () which can be selectively activated by being pushed down and, if a different stop pin () is selected, the activated stop pin (), which is biased into its non-activated position, having to be released from the stop position. In order to provide a crimping tool with a stop part for which there is advantageous adjustment from one activated stop pin to another activated stop pin, it is proposed that the activated stop pin () is retained by a spring latching means formed by a retaining spring (), and the spring latching means can be deactivated by a release movement of the stop part ().
