Description

Technical Field

[0001] The utility model belongs to the field of cable processing, and in particular relates to a wire stripping tool for leaky coaxial cables. Background Art

[0002] Leaky coaxial cable, also known as leaky cable, is a radio frequency coaxial cable that has both signal transmission and antenna function. By controlling the opening of the outer conductor, it can radiate and receive controlled electromagnetic wave energy evenly along the line, thereby covering the blind spots of the electromagnetic field and achieving smooth mobile communication.

[0003] In the production test or engineering use of leaky coaxial cables, it is necessary to strip the leaky cables for connector installation. Stripping means that the end face of the leaky cable must be cut flat and the sheath of the leaky cable must be cut off to a certain length, so that the sheath layer can be stripped off to expose the outer conductor for easy installation of the connector. The existing leaky coaxial cable stripping tools need to be manually rotated to cut the leaky cable sheath when stripping, and the end face of the leaky cable cannot be directly cut flat, but an additional tool needs to be used to achieve this. This method not only requires a lot of effort to operate the stripping tool, but also cannot use one tool to achieve all functions, and the flatness of the end face of the cut leaky cable varies from person to person, which will reduce work efficiency and the qualified rate of leaky cable stripping, and waste a lot of resources, resulting in poor practicability of the leaky coaxial cable stripping tool.
