Blade Moves Relative To Handle To Remove Insulation Patents (Class 81/9.43)
  • Patent number: 11811201
    Abstract: 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.

  • Patent number: 11630125
    Abstract: The invention relates to an adapter device (10, 110, 210) for positioning at least one conductor (68), such as a conductor pair, for example, of a cable (70) to be measured, which adapter device comprises a receiving device (12) and a holding clamp (14) which can be attached to the receiving device (12). Attaching the holding clamp (14) to the receiving device (12) fixes the holding clamp (14) in position and alignment relative to the receiving device (12). The holding clamp (14) is designed to receive and clamp the at least one conductor (68) of the cable (70) to be measured in sections in order to fix said cable in the position and alignment thereof relative to the holding clamp (14), such that an end section of the at least one conductor (68) extends beyond the holding clamp (14).

  • Patent number: 10910801
    Abstract: A stripping tool is formed by stripping pliers. In use, the stripping tool is closable with a closing stroke having a cutting stroke part, a stripping stroke part and a free stroke part. In the cutting stroke part, a closing movement moves at least one stripping blade into a closed position so that the stripping blade cuts into the insulating sheeting of a cable to be stripped. During the stripping stroke part, the cut insulating sheeting is partially stripped from the cable. In the free stroke part, the stripping blades are laterally passed alongside the partially stripped part of the insulating sheeting. A transition point from the stripping stroke part to the free stroke part is adjustable so that it is possible to change the length over which the separated part is partially stripped without any change of the length of the closing stroke of the stripping tool.

  • Patent number: 9923346
    Abstract: The invention relates to a stripping tool (1) comprising at least one stripping jaw. A cutting element (10, 11) is exchangeably assembled with the stripping jaw under use of a mounting groove (56, 57). Preferably, mounting and dismounting is performed along mounting axes (58, 59) having an orientation perpendicular to a pivot plane of the pliers jaws (3, 4). The inventive stripping tool (1) comprises an exchange position in which the mounting and dismounting of the cutting elements (10, 11) is possible, in particular through a cutaway (62, 63) of a side wall (64, 65) of the pliers jaws (3, 4). If the exchange position is left a movement of the cutting element (10, 11) is blocked by a securing element (66) formed by the side wall (64, 65) so that a securing of the position of the cutting element (10, 11) is provided.

  • Patent number: 9912131
    Abstract: The invention relates to a cable stripping tool (1). A cable stripping unit (5) is built with two cable stripping jaws (6, 7). The cable stripping jaws (6, 7) are pivoted towards each other in a pivot plane (9) during a cutting stroke. During a subsequent cable stripping stroke the cutting jaws (6, 7) are moved along a cable stripping axis (15). A mounting axis (58, 59) has an orientation vertical to the pivot plane (9). A cutting element (10, 11) is detachably mounted along the mounting axis (58, 59) with the cable stripping jaw (6, 7). Outside from an exchange position the cutting element (10, 11) is blocked against the removal along the mounting axis (58, 59). The exchange position is induced by the drive (16) of the cable stripping tool (1). In the exchange position the cutting element (10, 11) is freed with respect to a movement along the mounting axis (58, 59) so that demounting of the cutting element (10, 11) and mounting of a new cutting element (10, 11) is possible.

For example, instead of be able to strip 18, 16, 14, 12, and 10 gauges of wire, the device has cutters that strip 18, 12, 12, and 10 gauges of wire. Other variations include designs that can strip up to four wires of the same gauge. With this tool, a user can place two or more wires into the cutters and strip them at the same time. The number of bending holes can be increased to coincide with the number of wires capable of being stripped simultaneously. Slots may also be added instead of, or in conjunction with, the bending holes. Specific strippers can be designed for specific combinations of wire sizes and cables.
