Description

Technical Field

[0001] The utility model relates to a rotary wire stripper, in particular to a rotary wire stripper for making a coaxial cable connector. Background Art

[0002] During the on-site construction process, since the coaxial cable needs to be threaded and piped, the cable head is often packaged separately when the equipment manufacturer leaves the factory and needs to be made on-site. The production process of a coaxial cable head includes the following steps: 1. Peeling the skin, you need to use a utility knife to draw a circle on the surface of the cable, control the force so as not to damage the copper core, and also draw along the longitudinal direction of the cable, and then peel off the skin protective layer. 2. Peeling the top copper shielding layer and foam layer, you need to use a utility knife to draw a deep circle on the top of the cable, and then use pliers to clamp the top copper shielding layer and foam layer. 3. Insert the lower half of the connector and the spring ring and rubber ring. 4. Press the lace, use a steel ruler to turn the copper shielding layer outward to form a circle of lace. 5. Put on the lower half of the connector and tighten and clamp the lace. A skilled engineer needs about 4-5 minutes to make a cable head. Because there will be a certain error when cutting the skin and shielding layer each time, this will cause the copper core of some cables to be too long, resulting in the inability to tighten the cable head, and there is a certain rework rate.
