Abstract
Wire-stripping pliers include stripping jaws which close with and then move longitudinally relative to clamping jaws for stripping the insulation. A conductor end stop is mounted on a stripping jaw to define the stripped length and consists of an H-section member of which the web forms the stop abutment and the side limbs can flex in response to pressure on their upper ends for engaging and disengaging teeth on their lower ends from corresponding teeth on the sides of the stripping jaw.
Claims6
A wire-stripping tool comprising a pair of relatively pivotable operating members, a pair of relatively pivotable clamping jaws arranged to move towards one another in response to movement of the said members towards one another for gripping an insulated conductor inserted between the clamping jaws, a pair of stripping jaws disposed between the clamping jaws for closure therewith and provided with insulation-cutting means, a mechanical linkage operable by movement of the operating members towards one another and connected to the cutting jaws for longitudinally retracting these after closure thereof, and an end stop mounted on a said cutting jaw for limiting the depth of insertion of a conductor, and in which the said cutting jaw comprises a body with opposed side faces each provided with a longitudinal row of teeth, and the end stop is a member of substantially H-section with a central transverse web forming an end stop abutment and with side limbs each having at one end an in-turned hook portion toothed to grip said teeth of the cutting jaw when the end stop is mounted on said cutting jaw with its web between the two cutting jaws, each side limb having an opposite end forming an actuating lever, and each side limb being resiliently flexible about the web whereby on movement of said opposite ends towards each other the said one ends will be moved apart to release the teeth thereon from the said teeth provided on the cutting jaw.
A stripping jaw for a wire-stripping tool, comprising a jaw body having side walls and having disposed therein a cutting device for severing the the insulating sheath of a conductor and with a conductor stop which is disposed on the stripping jaw so as to be adjustable along the axis thereof relative to the cutting device, and wherein the stop has a middle web extending over the jaw body, gripping lugs which are mounted on both sides of said web and on the underside of which are provided with a hook-like, inwardly projecting ledge which is serrated at the free edge, the body side walls having longitudinal grooves with serrated bases, in which the serrated edges engage, and the lugs are double-armed actuating levers, each secured in its middle zone on the middle web by means of a hinge in the form of a zone of material of reduced thickness with the hinge axis parallel with the serrated ledge.
