Description

Technical Field

[0001] This utility model belongs to the field of electrical connection technology, specifically a wire terminal assembly. Background Technology

[0002] In electrical connection systems, terminal block assemblies play an indispensable role as key components for achieving reliable wire connection and electrical conduction.

[0003] In existing technologies, when using wire terminals, the wire is threaded through the middle of the terminal, and then the screw is rotated to clamp and hold the wire, thereby achieving effective electrical connection and conduction.

[0004] However, in the existing technology, when the wire is squeezed and clamped by rotating the screw, the surface of the wire is relatively smooth, which makes it easy for the screw to shift when it descends and squeezes, resulting in an unstable fixation. This will have a certain impact on the performance of the terminal. Therefore, a wire clamping terminal assembly is proposed to address the above problems. Utility Model Content

[0007] Preferably, a heat-absorbing plate is fixedly connected to the inner side wall of the terminal body; a limiting groove is formed in the side wall of the heat-absorbing plate; a plurality of heat sinks are uniformly fixedly connected to the side wall of the heat-absorbing plate; the heat sinks penetrate the wall of the terminal body and are fixedly connected to it.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1-4This utility model provides a wire crimping terminal assembly, including a terminal body 1; a pair of fixing blocks 11 are provided on the inner side wall of the terminal body 1; the fixing blocks 11 are symmetrically arranged on both sides of the terminal body 1 and have the same structure; a pair of springs 12 are symmetrically fixed to the side wall of the fixing blocks 11; the springs 12 are fixedly connected to the terminal body 1; a pair of clamping plates 13 are symmetrically fixed to the side wall of the fixing blocks 11; the clamping plates 13 are arc-shaped; in use, when a wire is inserted into the middle of the terminal body 1, the wire can be used to squeeze and push the fixing blocks 11 to open them. The elasticity of the spring 12 can apply a certain reaction force, thereby causing the fixing block 11 to squeeze and clamp the wire. At the same time, the clamping plate 13 can ring and concentrate the loose wire. Then, when the screw is rotated and lowered, the screw can squeeze the fixing block 11 open, and finally fix the wire. In this process, the terminal body 1 can play a pre-fixing role when squeezing and clamping the wire, improving the convenience of fixing the wire and reducing the occurrence of displacement during fixing. At the same time, the clamping plate 13 can increase the concentration of the wire when it is fixed, and improve the stability of the wire during use.

[0025] Furthermore, such as Figures 1-4 As shown, a heat-absorbing plate 2 is fixedly connected to the inner wall of the terminal body 1; a limiting groove 21 is formed on the side wall of the heat-absorbing plate 2; a plurality of heat sinks 22 are uniformly fixedly connected to the side wall of the heat-absorbing plate 2; the heat sinks 22 penetrate the wall of the terminal body 1 and are fixedly connected to it; in use, when the wire is squeezed and clamped by screws, the wire can be placed on the side wall of the limiting groove 21, and the limiting groove 21 is used to limit the wire, so that it is in contact with the heat-absorbing plate 2. Then, the heat generated by the wire during use will be absorbed by the heat-absorbing plate 2 and conducted to the wall of the heat sink 22, and the heat sink 22 will release the heat to the outside. In this process, the heat dissipation effect of the wire during use can be increased, the safety hazards caused by heat accumulation can be reduced, and the protective function of the terminal body 1 during use can be improved, thereby increasing safety.

[0026] Furthermore, such as Figures 1-4 As shown, the side wall of the fixing block 11 is provided with a plurality of grooves 3; the grooves 3 are evenly distributed on the side wall of the fixing block 11 and have the same structure; the side wall of the groove 3 is rotatably connected to a roller 31; in use, when the screw descends and pushes the fixing block 11 open, the roller 31 can be driven to rotate as the screw moves, so as to assist the movement of the screw. In this process, it can play an auxiliary role when the screw slides on the surface of the fixing block 11, reduce the friction between the screw and the fixing block 11, and thus increase the sliding speed of the screw on the surface of the fixing block 11.

[0027] Furthermore, such as Figures 1-4As shown, a rubber pad 4 is fixed to the side wall of the fixing block 11. In use, when the fixing block 11 clamps the wire, the rubber pad 4 can fully adhere to the surface of the wire, blocking it between the two. The flexibility of the rubber pad 4 protects the wire. In this process, the fixing block 11 can play a protective role when clamping the wire, reduce the wear caused by the fixing block 11 clamping the wire, thereby increasing the service life of the wire and improving the stability of electrical transmission.

[0028] Furthermore, such as Figures 1-4 As shown, a pair of fixing strips 5 are symmetrically fixed to the side wall of the rubber pad 4. In use, the fixing strips 5 can be used to connect and fix the wall of the rubber pad 4, connecting them together as a whole. In this process, the tear resistance of the rubber pad 4 can be increased during use, reducing the occurrence of tearing damage during long-term use, thereby increasing the service life of the rubber pad 4.

[0029] Furthermore, such as Figures 1-4 As shown, a pair of epoxy resin coatings 6 are symmetrically sprayed on the sidewall of the terminal body 1. In use, the epoxy resin coatings 6 cover the surface of the terminal body 1, which can protect the surface of the terminal body 1. In this process, the corrosion resistance of the terminal body 1 during use can be increased, and the insulation effect can be improved, thereby increasing the protection effect of the terminal body 1.

[0030] Working principle: During use, when the wire is threaded into the middle of the terminal body 1, the wire can squeeze and push the fixing block 11, pushing it open. The elasticity of the spring 12 applies a certain reaction force, causing the fixing block 11 to squeeze and clamp the wire. Simultaneously, the clamping plate 13 can ring and gather loose wires. Then, by rotating the screw to lower it, the screw can push the fixing block 11 open, finally fixing the wire. During use, when the screw squeezes and clamps the wire, it can be placed on the side wall of the limiting groove 21. The limiting groove 21 limits the wire, making it fit against the heat-absorbing plate 2. The heat generated by the wire during use will then be absorbed by the heat-absorbing plate 2. The heat is conducted to the wall of the heat sink 22, and the heat sink 22 releases the heat to the outside. When the screw descends and pushes open the fixing block 11, the movement of the screw can drive the roller 31 to rotate, thereby assisting the movement of the screw. When the fixing block 11 clamps the wire, the rubber pad 4 can fully adhere to the surface of the wire, blocking it between the two. The flexibility of the rubber pad 4 protects the wire. When the fixing strip 5 is used, the wall of the rubber pad 4 can be connected and fixed, connecting them together as a whole. When the epoxy resin coating 6 is used to cover the surface of the terminal body 1, the surface of the terminal body 1 can be protected.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
