In electrical equipment, wiring terminals are used to connect wires so that the circuit can work properly, and at the same time, it is convenient for the connection, disconnection, and maintenance of wires.

[0003] When connecting the wire harness to the wiring terminal, according to the wire specification and terminal model, determine the length of the wire that needs to be stripped, and then insert the stripped wire core into the corresponding position of the terminal. During this process, it is necessary to ensure that the wire core is completely inserted without any exposed metal parts and is in close contact with the contact surface inside the terminal. Then, fix the wire harness through the wiring terminal. However, directly fixing the wire harness on the wiring terminal is likely to cause the joint position to break, resulting in a leakage accident and affecting the normal use of the equipment. Therefore, we have proposed a new type of wiring terminal with anti-break joints. Summary of the Utility Model

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1, as Figure 1 - Figure 4 shown, the present invention provides a terminal for preventing the breakage of the connector, including a terminal body 1. Anti-break components 2 are provided at both the front and rear ends of the terminal body 1. The anti-break component 2 includes a fixed clamping block 201. Slide blocks 202 are connected to both side surfaces of the fixed clamping block 201. A connecting rod 203 is connected between the two groups of slide blocks 202. A lifting clamping block 204 is sleeved on the surfaces of the two groups of slide blocks 202. Chutes 205 are opened on both sides of the lifting clamping block 204. Slide rods 206 are connected to both side surfaces of the lifting clamping block 204 close to the chutes 205. Slide holes 207 are opened on both side surfaces of the connecting rod 203. A threaded hole 208 is opened at the central position of the surface of the connecting rod 203. A threaded rod 210 is arranged inside the threaded hole 208. A handle 211 is connected to the top of the threaded rod 210. A bearing 209 is connected to the bottom of the threaded rod 210. A fixed connection is formed between the threaded rod 210 and the handle 211. A rotational connection is formed between the threaded rod 210 and the bearing 209. A threaded connection is formed between the threaded rod 210 and the connecting rod 203 through the threaded hole 208. The position and size of the slide rod 206 match the position and size of the slide hole 207. A sliding connection is formed between the slide rod 206 and the slide hole 207. The inner wall of the chute 205 fits the outer surface of the slide block 202. The size of the fixed clamping block 201 is the same as that of the lifting clamping block 204.

[0024] The effect achieved by the entire Embodiment 1 is that after connecting all the wire harnesses to the terminal block body 1, the handle 211 can be rotated forward, so that the handle 211 can drive the threaded rod 210 to rotate threadedly. The bearing 209 can improve the stability of the rotation of the threaded rod 210. When the handle 211 rotates, the threaded rod 210 can rotate threadedly with the connecting rod 203 through the threaded hole 208, and drive the lifting clamp block 204 to move downward through the threaded rotation. While the lifting clamp block 204 moves downward, it will also slide with the slider 202 through the chute 205 to improve the stability of the lifting of the lifting clamp block 204. And it will also drive the slide bar 206 to slide in the slide hole 207, so that the lifting clamp block 204 can move downward and cooperate with the fixed clamp block 201 to clamp and fix the wire harness. When it is necessary to extract the wire harness from the terminal block body 1, rotate the handle 211 in the reverse direction to drive the threaded rod 210 to rotate in the reverse direction, so that the lifting clamp block 204 can move upward, and then the wire harness can be extracted from the terminal block body 1. Through the clamping between the fixed clamp block 201 and the lifting clamp block 204, the protection of the wire harness joint is realized, the problem of joint fracture is avoided, and the risk of electric leakage accidents caused by joint fracture is reduced.

[0025] Embodiment 2 is as Figure 1 , Figure 2 and Figure 5 shown. Splicing components 3 are connected to both sides of the terminal block body 1. The splicing component 3 includes a slide rail 301, and the slide rail 301 is connected to one side of the terminal block body 1. A convex block 303 is connected to the other side of the terminal block body 1. A magnet 304 is embedded on the outer surface of the convex block 303, and a magnetic attraction strip 302 is embedded on the inner wall of the slide rail 301. A sliding connection is formed between the slide rail 301 and the convex block 303, and a magnetic attraction connection is formed between the magnetic attraction strip 302 and the magnet 304.

[0026] The effect achieved by the entire Embodiment 2 is that when it is necessary to splice two sets of terminal block bodies 1, the convex block 303 of one set of terminal block bodies 1 can be pushed into the slide rail 301 of the other set. When the convex block 303 is completely pushed into the slide rail 301, the magnetic attraction strip 302 will also be magnetically attracted and fixed to the magnet 304, thereby completing the splicing between the two sets of terminal block bodies 1 and improving the convenience of splicing the terminal block bodies 1.

[0027] Working principle: After connecting all the wire harnesses to the terminal block body 1, the handle 211 can be rotated. The downward movement of the lifting clamp block 204 is driven by the threaded rotation, so that the lifting clamp block 204 can cooperate with the fixed clamp block 201 to fix the wire harness, avoiding the problem of joint fracture and reducing the risk of electric leakage accidents caused by joint fracture. When it is necessary to splice two groups of terminal block bodies 1, the two groups of terminal block bodies 1 can be directly snap-fitted through the slide rail 301 and the convex block 303, improving the convenience of splicing the two groups of terminal block bodies 1.

[0028] The above is only the preferred embodiment of the present invention, and does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still belong to the protection scope of the technical solution of the present invention.
