  • Patent number: 11886028
    Abstract: A rollable ribbon separator tool for separating fibers in a rollable ribbon, the rollable ribbon separator including a chassis having a length and a guide surface along the chassis length for receiving a first portion of a rollable ribbon in a flattened position, the guide surface for positioning the first portion of the rollable ribbon having a first node with selected fibers to be separated, the selected fibers being positioned flat on the guide surface. The rollable ribbon separator includes a blade securable to the chassis, the blade having a cutting edge positioned toward the guide surface at an acute angle to the guide surface. The angle of the blade cutting edge with respect to the guide surface allows the cutting edge to urge the first portion of the flattened ribbon fibers against the guide surface when the fibers are drawn through the chassis along the guide surface.

  • Patent number: 9791397
    Abstract: The invention relates to a device for detecting contact of a tool (2a, 2b) with an electrical conductor (5b) encased by an electrical insulation (5a). In order to ensure a reliable, robust and simple display of the tool-conductor contact for potential-free and short cable lengths, the tool (2a, 2b) consisting of an electrically conductive material is fastened to a tool holder (1a; 1b) made of electrically conductive material. A thin electrical insulation is provided between tool (2a, 2b) and tool holder (1a, 1b) so that these components together with the coaxial cable form a capacitor (CS). An inductance (La; Lb) is connected parallel to this so that a high-Q LC resonant circuit is formed between tool and tool holder. The electronic circuit arrangement excites the resonant circuit and determines characteristic oscillation parameters of this resonant circuit.

  • Patent number: 7918148
    Abstract: A wire stripping knife comprises a handle having one end provided with a hanging portion to be hung to a desired position, and the other end fixed with a blade. The end of the handle, which is fixed with the blade, is pivoted with a clamping member. One end of the clamping member, which is adjacent to the blade, is provided with different-sized stripping notches. The handle and the clamping member each are provided with engaging portions for mutual engagement. The distal end of the blade is formed with a cutting surface vertical to the cutting edge for cooperating with a guiding plate at one end of the clamping member to strip off the insulation more quickly with high safety.

  • Patent number: 7870811
    Abstract: In order to improve the stripping process, a thermal stripping apparatus is proposed which has a thermal stripper with a first holder section and a second holder section. The holder sections are designed to accommodate and hold at least one coating glass fiber, wherein the first holder section is arranged such that it can move with respect to the second holder section along an accommodated glass fiber. A housing is also provided, having a handle section and an appliance section, in which the thermal stripper is accommodated. A drive unit, which has a lever, is operatively connected to the thermal holder section of the thermal stripper such that a movement with respect to the handle section is converted to a movement of the first holder section.

  • Publication number: 20100101373
    Abstract: A cable end preparation tool is for a coaxial cable and has a C-shaped body with an opening therein to receive the coaxial cable and a side defining a saw guide to receive a saw blade thereagainst. The C-shaped body includes a gripping rib to fit in a valley of a corrugated outer conductor when the coaxial cable is in the opening. At least one stabilizing rib is adjacent the gripping rib to receive a crest of the corrugated outer conductor thereagainst when the coaxial cable is in the opening. The C-shaped body also includes a rotation guide feature receives the inner conductor. A cutting blade extends outwardly from the C-shaped body for removing a portion of a dielectric between the inner conductor and the corrugated outer conductor as the C-shaped body is rotated about the rotation guide feature.

  • Patent number: 7694420
    Abstract: A coaxial cable preparation tool is provided wherein the tool includes a body, having a first end and a second end, the first end including a first cavity configured to accommodate insertion of a coaxial cable therein. An outer conductor blade is located near the first end of the body and is movably operable with the body to cut an outer jacket, an outer conductor, and an inner dielectric of the cable when the cable is inserted into the first cavity. A center conductor chamfering member is positioned at the back of a second cavity, the second cavity extending from the second end of the body. A dielectric coring blade is positioned within the second cavity, and a jacket stripping blade is positioned at least partially within the second cavity. A corresponding method of coaxial cable preparation is provided.

    Abstract: Provided is a core wire contact detection device which detects contact between a strip blade and a core wire when a sheath of an electric wire is stripped by the strip blade. The core wire contact detection device includes a vibration detection unit capable of detecting a vibration in a frequency range including a vibration frequency generated due to the contact between the core wire and the strip blade, and a contact state determination processing unit which determines that the strip blade and the core wire are in contact with each other when an amplitude of the detected vibration exceeds a predetermined threshold value.

  • Publication number: 20100000372
    Abstract: A cable stripper is comprised of two components, each component including a main body portion, a coupling device at one end of the main body portion and a T-shaped handle disposed at an opposite end of the main body portion. The coupling device rotatably couples the two components together. A channel runs along an interior length of each of the main body portions, which provides a path into which the cable to be stripped is inserted. A blade housing on at least one of the components of the main body portion securely holds a utility knife blade with a predetermined amount of the tip or edge of the blade protruding into the channel. The exposed portion of the blade pierces the sheath or covering of the cable by a precise, predetermined amount.
