[0002] A wiring terminal is also called a copper nose, wire nose, copper wiring nose, copper pipe nose, aluminum nose, etc., and has different names in different places and industries. It is a connector used to connect wires and cables to electrical equipment, with a screw hole for fixed connection at the top and the copper or aluminum core of the stripped wire and cable at the end.

[0003] The existing wiring terminal with rotary clamping clamps and fixes the copper wire by extruding an elastic tightening strip. However, after long-term extrusion or multiple repeated extrusions of the tightening strip, the elastic performance of the tightening strip will be affected, resulting in the inability of the tightening strip to rebound and reset after use, affecting its reuse.

[0004] After stripping the insulating sleeve at the end of the cable, the copper wire at the end of the cable will spread out, resulting in the inability to insert the copper wire into the wiring cylinder and requiring the assistance of other tools, which is inconvenient to use. Content of the Utility Model

[0005] The purpose of the utility model is to provide a wiring terminal with rotary clamping, which has the characteristics of avoiding the influence on reuse due to the inability of the tightening strip to rebound and reset and inserting the spread copper wire into the wiring cylinder without the assistance of other tools.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a wiring terminal with rotary clamping, including a wiring cylinder, wherein a plurality of uniformly distributed grooves are opened on the inner wall of the wiring cylinder, a plurality of notches communicating with the grooves are penetrated through the outer wall of the wiring cylinder, a clamping plate is movably connected inside the groove, a moving block fixedly connected with the clamping plate is movably connected inside the notch, and the other side wall of the moving block extends to the outside of the notch.

[0007] A rotating outer cylinder is rotatably connected to the outer wall of the wiring cylinder, and a moving ring matched with the moving block is threadedly connected to the inner wall of the rotating outer cylinder.

[0008] To facilitate the entry of the spread copper wire into the wiring cylinder, preferably, the lower end of the wiring cylinder is provided with a flared structure as a wiring terminal with rotary clamping of the utility model.

[0009] To prevent the moving ring from rotating with the rotating outer cylinder, preferably, a plurality of uniformly distributed sliding grooves are opened on the inner wall of the moving ring, and a sliding strip matched with the sliding groove is fixedly connected to the other side wall of the moving block.

[0010] In order to make the multiple moving blocks approach each other, as a preferred embodiment of the rotary clamping terminal of the present invention, the inner wall of the moving ring and the other side wall of the moving block are both configured as matching inclined structures.

[0011] In order to make the clamping plate closely contact with the copper wire, as a preferred embodiment of the rotary clamping terminal of the utility model, the clamping plate is configured as an arc structure.

[0012] In order to facilitate the connection between the wiring terminal and the terminal post on the machine, as a preferred rotatable clamping wiring terminal of the utility model, the upper end surface of the wiring barrel is fixedly connected with a wiring ear.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] Since the lower end of the wiring barrel is set as a flared structure, the lower end of the wiring barrel can gather the scattered copper wires, making it convenient for the scattered copper wires to enter the wiring barrel, and then the outer barrel is rotated, and the rotating outer barrel drives the moving ring to move downward through the thread, and the moving ring can squeeze the multiple moving blocks to approach each other, and then push the multiple clamping plates to approach each other, so that the copper wires entering the wiring barrel are clamped and fixed by the multiple clamping plates;

[0015] When replacing the cable, the outer cylinder is rotated in the opposite direction, and the rotating outer cylinder drives the movable ring to move upward. The sliding groove and the sliding bar can prevent the movable ring from rotating with the rotating outer cylinder, and at the same time, the multiple movable blocks can be pulled to move away, thereby driving the multiple clamping plates to reset and loosening the copper wire in the wiring barrel, so as to replace the cable.
