Description
Technical Field
[0001] This invention relates to the field of wire clamping technology, and more specifically to a wire clamping device. Background Technology
[0002] Cable clamps are suitable for use in communication base stations, repeaters, indoor coverage systems, wireless paging, and microwave communication systems. They serve to secure transmission cables in towers, cable trays, indoor and outdoor installations, as well as in subways and tunnels, and can be used in various high and low temperature ranges. Feeder clips are economical, practical, robust, durable, and reliable in positioning, making them widely used in many communication projects. CN214543477U discloses a novel feeder clamp that provides a simple snap-fit structure during use through a limiting plate, a limiting groove, and matching auxiliary structures. This snap-fit structure provides stability. Furthermore, connecting strips and curved plates are provided on the outer side of the limiting pads for fixation. However, existing wire clamping tools like this have several problems during use: the upper, middle, and lower limiting pads are snapped together by the limiting plate and limiting groove, but this snap-fit plate-groove connection results in poor overall stability of the upper, middle, and lower limiting pads. When the feeder clamp or the clamped wire is subjected to significant external force, the upper limiting plate and limiting groove are easily detached, affecting the stability of the clamped wire. Moreover, the wire clamping tool can only clamp a single specification of wire; different wire models require different clamping structures for adaptation, resulting in limited adaptability. Therefore, there is an urgent need for those skilled in the art to design a novel wire clamping device. Summary of the Invention
[0003] The problem to be solved by the present invention is to provide a wire clamping device that achieves double locking and fixation of the limiting connection part by means of a positioning locking part and a rotating self-locking component, which can effectively prevent the upper, middle and lower parts of the limiting connection part from falling off, thereby ensuring the stability of the clamped wire; it can clamp multiple specifications and multiple wires, and has extremely wide adaptability.
