Then, bolts are inserted into the through holes to connect the two copper busbars, thus connecting the two cables. The cable terminals are secured with bolts. However, under long-term vibration, the bolts can gradually loosen over time, making them prone to loosening and falling off. Summary of the Invention

[0004] To overcome the technical defects of the existing technology, this utility model provides a cable terminal block that prevents loosening. The lateral positioning mechanism fixes the U-shaped pressure block laterally, thus achieving a good anti-loosening effect under the double fixation.

The insulating base is provided with an installation groove for installing the conductive component. The insulating cover is installed on the insulating base by bolts and presses and fixes the conductive component. The conductive component has conductive connecting parts on both sides, the conductive connecting parts have downwardly recessed anti-detachment grooves, and the insulating base has a U-shaped pressure block, and the U-shaped pressure block and the conductive connecting parts form a socket for cable insertion, and the insulating cover is equipped with fastening bolts, and the top of the U-shaped pressure block has a first threaded hole for the end of the fastening bolt to be inserted. The insulating base is provided with a slot for inserting the bottom end of the U-shaped pressure block, and the insulating base is equipped with a lateral positioning mechanism for laterally positioning the bottom end of the U-shaped pressure block.

[0006] Preferably, the lateral positioning mechanism includes a mounting cavity disposed at the bottom of the insulating base and installed laterally, and a positioning block is installed in the mounting cavity. The inner end of the positioning block is provided with a plurality of first engagement teeth. The positioning block is provided with a through hole, and the inner end side of the mounting cavity is provided with a second threaded hole corresponding to the through hole. A lateral bolt is installed between the through hole and the second threaded hole, and the side of the U-shaped pressure block is provided with a second engagement tooth that cooperates with the first engagement teeth.

[0011] The beneficial effects of this utility model are: 1. This utility model provides a downwardly recessed anti-loosening groove on the conductive connection part, and then forms a socket for cable insertion between the U-shaped pressure block and the conductive connection part. The fastening bolt drives the U-shaped pressure block to press down and lock the cable. After the U-shaped pressure block is pressed down, the U-shaped pressure block is laterally fixed by the lateral positioning mechanism.

[0017] like Figures 1 to 5 As shown, this embodiment provides an anti-loosening cable terminal block, including an insulating base 1, an insulating cover 2, and a conductive component 3. The insulating base 1 is provided with a mounting groove 4 for mounting the conductive component 3. The insulating cover 2 is bolted to the insulating base 1 and presses and fixes the conductive component 3. The conductive component 3 has conductive connection parts 5 on both sides. The conductive connection parts 5 have downwardly recessed anti-detachment grooves 6. The insulating base 1 has a U-shaped pressure block 7. The U-shaped pressure block 7 and the conductive connection parts 5 form a socket for cable insertion. The insulating cover 2 is equipped with fastening bolts 8. The top of the U-shaped pressure block 7 has a first threaded hole 9 for the end of the fastening bolt 8 to be inserted. The insulating base 1 is provided with a slot 10 for inserting the bottom end of the U-shaped pressure block 7. The insulating base 1 is equipped with a lateral positioning mechanism for laterally positioning the bottom end of the U-shaped pressure block 7. By providing a downwardly recessed anti-loosening groove 6 on the conductive connection part 5, a socket for cable insertion is formed between the U-shaped pressure block 7 and the conductive connection part 5. The fastening bolt 8 drives the U-shaped pressure block 7 to press down and lock the cable. After the U-shaped pressure block 7 is pressed down, the lateral positioning mechanism further fixes the U-shaped pressure block 7 laterally. With this double fixing effect, a good anti-loosening effect is achieved.

[0018] The lateral positioning mechanism includes a mounting cavity 11 located at the bottom of the insulating base 1 and installed laterally. A positioning block 12 is installed inside the mounting cavity 11. The inner end of the positioning block 12 is provided with multiple first engagement teeth 13. The positioning block 12 is provided with a through hole 14. The inner end of the mounting cavity 11 is provided with a second threaded hole 15 corresponding to the through hole 14. A lateral bolt 16 is installed between the through hole 14 and the second threaded hole 15. The side of the U-shaped pressure block 7 is provided with a second engagement tooth 17 that engages with the first engagement teeth 13. By setting a specific lateral positioning mechanism, the bottom end of the U-shaped pressure block 7 is laterally positioned. The positioning block is fixed by the lateral bolt. When positioning the positioning block, the first engagement teeth at the inner end of the positioning block engage with the second engagement teeth on the side of the U-shaped pressure block 7, thus achieving the positioning function and preventing the U-shaped pressure block 7 from loosening and falling off, thereby achieving the anti-loosening function.

[0019] The mounting cavity 11 is connected to the slot 10, which facilitates the engagement of the first biting tooth 13 and the second biting tooth 17.

[0020] Both the gate-shaped pressure block 7 and the positioning block 12 are made of high-strength material, which makes them less prone to deformation and thus provides a better positioning effect.

[0021] The positioning block 12 is provided with a recessed groove for accommodating the cap of the lateral bolt 16. The positioning block 12 is made of insulating material and serves an insulating function.

[0022] The insulating cover 2 is provided with a storage groove for storing the cap of the fastening bolt 8, so as to store the cap of the fastening bolt 8 and avoid the phenomenon of not touching it.

[0023] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0024] During operation, a downwardly recessed anti-loosening groove 6 is provided on the conductive connection part 5. Then, a socket for cable insertion is formed between the U-shaped pressure block 7 and the conductive connection part 5. The fastening bolt 8 drives the U-shaped pressure block 7 to press down and lock the cable. After the U-shaped pressure block 7 is pressed down, the U-shaped pressure block 7 is laterally fixed by the lateral positioning mechanism. Under the action of double fixation, a good anti-loosening effect is achieved. The positioning block is fixed by the lateral bolt. When the positioning block is positioned, the first biting tooth at the inner end of the positioning block engages with the second biting tooth on the side of the U-shaped pressure block 7, which plays a positioning role and prevents the U-shaped pressure block 7 from loosening and falling off, thus playing an anti-loosening role.

[0025] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
