Description

Technical Field

[0001] This utility model relates to the field of wire manufacturing technology, and in particular to a pre-tightening conductor mechanism. Background Technology

[0002] An electrical wire is a conductor capable of carrying electric current, typically composed of a conductor (such as metals like copper or aluminum) and an insulation layer (such as plastic or rubber). In the wire manufacturing process, one step involves trimming and stripping the wire's insulation, primarily processing the ends of the wire to facilitate connections or soldering.

[0003] Before the wire is crimped and stripped, it needs to be pulled out of the coiled wire by the wire guiding mechanism. The current wire guiding mechanism usually consists of one or more rollers. The rollers guide the wire and a pull device is installed at the end of the wire guiding mechanism. The pull device pulls out the wire guided by the rollers, so that the wire can enter the crimping and stripping process.

[0004] Rollers are typically designed to guide wires along a specific path. Therefore, as the wire passes over the rollers, it may bend or deform due to factors such as the shape, size, or material of the rollers. If the conductor mechanism consists of multiple rollers, there may be gaps between them. These gaps may cause the wire to wobble or jump as it passes through, thus affecting the straightness of the wire. When stripping the insulation, a bent wire may make it difficult for the stripping tool to cut the insulation layer accurately, resulting in incomplete stripping or damage to the internal conductor. A bent wire may also cause uneven ends when terminating, affecting the fit with the connector and the stability of the electrical connection. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a pre-tensioning conductor mechanism that can effectively solve the problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0011] Furthermore, it also includes a nut, wherein the end of the screw exposed outside the slider is fixed with a nut, and a gap is formed between the nut and the slider to allow the slider to move up and down.

[0012] Furthermore, it also includes several connecting rods, and several second wire screws are fixedly connected to the slider through the connecting rods.

[0013] Furthermore, the base is provided with a mounting groove, and the shaft is disposed in the mounting groove.

[0014] Furthermore, the left and right sides of the slider abut against the inner side of the base.

[0015] Furthermore, the second wire module is provided in multiple ways, and also includes a support rod. One end of the support rod is fixed to the frame, and several second wire modules are rotatably passed through the support rod in sequence.

[0016] Furthermore, the wire hole includes a first wire hole and a third wire hole, with a plurality of first wire holes spaced apart in the first wire module and a plurality of third wire holes spaced apart in the third wire module.

[0017] Furthermore, it also includes a bolt, the lower end of the shaft is provided with an annular groove, one end of the base is provided with a fixing hole, the bolt is threadedly connected to the fixing hole, and one end of the bolt passes through the annular groove.

[0018] By adopting the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0019] Firstly, through the first, second, third, and fourth conductor modules, the wire is effectively guided and kept in a straight line, reducing bending and deformation during transmission and thus improving the straightness of the wire. The wire is placed in the keyway of the first conductor screw and tightened by the thread of the second conductor screw, which not only fixes the position of the wire but also reduces shaking or jumping during transmission, enhancing the stability of the wire. Because the wire is effectively straightened and fixed, the stripping tool can cut the insulation layer more easily and accurately, thus avoiding the problem of incomplete stripping or damage to the internal conductor, resulting in a smoother end when terminating.

[0020] Secondly, the height of the second conductor screw can be easily adjusted through the adjustment device, thereby adjusting the degree of compression on the wire. This design gives the conductor mechanism a certain degree of adjustment flexibility, which can adapt to wires of different diameters and materials. Attached Figure Description
