Abstract
Techniques, systems, and articles are described for preparing electrical cables for connections to a power grid. In one example, a system includes a handheld cable preparation device configured to cut one or more layers of an electrical cable and a computing device configured to control the cable preparation device to cut the one or more layers of the electrical cable.
Claims17
An electrical cable preparation device configured to remove layers of an electrical cable, the device comprising:
- a handheld rotatable tool head comprising:
- a blade holder assembly;
- a plurality of rollers mechanically engaged with the blade holder assembly and arranged to surround a circumference of the electrical cable when the electrical cable is inserted into the blade holder assembly;
- and
- a plurality of cutting tools mechanically engaged with the blade holder assembly and arranged to rotate around the electrical cable when the electrical cable is inserted into the blade holder assembly,
- wherein the plurality of cutting tools includes at least one spring loaded cutting tool, and
- wherein the plurality of cutting tool includes a first cutting tool configured to remove a jacket layer of the electrical cable and a second cutting tool configured to remove an insulation layer of the electrical cable;
- and
- a driver configured to selectively engage and disengage the handheld rotatable tool head to adjust a radial depth of the plurality of rollers and/or a radial depth of the at least one of the plurality of cutting tools, wherein the plurality of rollers and the plurality of cutting tools are configured to rotate around the electrical cable to cause first cutting tool to remove the jacket layer of the electrical cable and to cause the second cutting tool to remove the insulation layer of the electrical cable,
- wherein the driver comprises a screwdriver-and-camshaft assembly.
An electrical cable preparation device configured to remove one or more layers of an electrical cable, the device comprising:
- a handheld rotatable tool head comprising:
- a plurality of rollers;
- and
- at least one cutting tool, and
- a driver configured to selectively engage and disengage the handheld rotatable tool head to adjust a radial depth of the plurality of rollers and/or a radial depth of the at least one cutting tool, wherein the driver comprises a screwdriver-and-camshaft assembly,
- wherein the cable preparation device is configured to remove the one or more layers of the electrical cable by at least being configured to:
- insert the at least one cutting tool into the electrical cable to a first predetermined depth;
- rotate the at least one cutting tool to a predetermined angle;
- and
- rotate the tool head with the at least one cutting tool at the first predetermined depth to remove the one or more layers.
An electrical cable preparation device configured to remove one or more layers of an electrical cable, the device comprising:
- a handheld rotatable tool head comprising:
- a plurality of rollers;
- and
- at least one cutting tool,
- a clamp configured to couple to the electrical cable;
- a piston configured to couple to the clamp at a first end and to the handheld rotatable tool head at a second end;
- and
- a driver configured to selectively engage and disengage the handheld rotatable tool head to adjust a radial depth of the plurality of rollers and/or a radial depth of the at least one cutting tool, wherein the driver comprises a screwdriver-and-camshaft assembly.
An electrical cable preparation device configured to remove one or more layers of an electrical cable, the device comprising:
- a handheld rotatable tool head comprising:
- a plurality of rollers;
- and
- at least one cutting tool;
- a driver configured to selectively engage and disengage the handheld rotatable tool head to adjust a radial depth of the plurality of rollers and/or a radial depth of the at least one cutting tool, wherein the driver comprises a screwdriver-and-camshaft assembly;
- and
- a clamp with a retroreflector.
