[0014] Beneficial effects:

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention involves wrapping the cable around a fixing member or fitting a copper lug onto the fixing member, then inserting the fixing member into the connector. The fixing part enters along the groove direction. At this point, simply rotating the fixing member allows the fixing part to enter the fixing groove, completing the connection. Furthermore, an elastic element applies force, increasing the friction between the fixing part and the fixing groove, preventing displacement of the fixing member due to external forces. Simultaneously, the elastic element also presses the cable or copper lug firmly against the copper busbar, ensuring stable wiring. However, the presence of the cable or copper lug increases the distance between the fixing member and the copper busbar, allowing for adjustment of the fixing part's insertion height into fixing grooves of different heights to accommodate cables and copper lugs of varying thicknesses. This design overcomes the shortcomings of traditional technologies, improves wiring efficiency, and reduces workload. Attached Figure Description

[0026] Reference example Figures 1 to 4 A cable branch box for improving wiring efficiency includes a box body 1, a plurality of copper busbars 2 inside the box body 1, a plurality of mounting holes 21 in the copper busbars 2, a liftable connector 3 in the mounting holes 21, a plurality of equally spaced sliding grooves 31 evenly distributed around a dot as the axis on the inner wall of the connector 3, a plurality of fixing grooves 32 from bottom to top on one side of the sliding grooves 31, a fixing member 4 in the sliding grooves 31, an elastic member 5 inside the fixing member 4, and a downward force applied to the connector 3, the fixing member 4 has a fixing part 41 corresponding to the fixing groove 32, and the fixing member 4 is rotated so that the fixing part 41 is placed in any fixing groove 32;

[0027] It is worth mentioning that the mounting hole 21 is provided with a mounting groove 22 at the entrance, and the mounting groove 22 is provided with a connecting hole 23. The mounting groove 22 keeps the cover ring 6 flush with the surface of the copper busbar 2, and the connecting hole 23 facilitates connection and fixation with the cover ring 6.

[0028] It is worth mentioning that the inner wall of the mounting hole 21 is provided with several limiting grooves 24 evenly distributed around the dot as the axis. The limiting grooves 24 limit the descent distance of the connector 3.

[0029] It is worth mentioning that the mounting groove 22 is provided with a cover ring 6, the cover ring 6 is provided with a through hole 61 for the fastener 4 to pass through, the cover ring 6 is provided with a connecting part 62, the connecting part 62 is provided with a screw 7 and threadedly connected to the connecting hole 23, the cover ring 6 is provided with an extension part 63 and is inserted into the top of the limiting groove 24, the extension part 63 restricts the distance of the connecting part 3 rising, and at the same time prevents the connecting part 3 from disengaging from the limiting groove 24;

[0030] It is worth mentioning that the connector 3 is provided with a limiting part 33 and is slidably disposed in the limiting groove 24. The connector 3 is provided with a cavity 34 for accommodating the fixing part 4. The sliding groove 31 is disposed on the inner wall of the cavity 34. When the fixing part 4 is rotated, the limiting part 33 and the side wall of the limiting groove 24 abut against each other to prevent the connector 3 from rotating with the fixing part 4. In order to enhance the connection strength between the cable, the copper lug and the copper busbar 2, an upward force needs to be applied to the connector 3 so that the fixing part 41 enters the fixing groove 32 near the bottom of the cavity 34. This increases the pressure on the elastic part 5, thereby releasing a greater force, improving the connection stability and reducing the contact resistance value.

[0031] It is worth mentioning that the fastener 4 includes an action part 42 and a rod part 43. The action part 42 abuts against the cover ring 6. The outer wall of the action part 42 is provided with knurling 421, which increases the friction force for the user to rotate the fastener 4.

[0032] It is worth mentioning that the rod 43 is provided with a blind hole 431, and the fixing part 41 is provided on the outer wall of the rod 43;

[0033] It is worth mentioning that one end of the elastic element 5 is provided with a washer 51. The washer 51 is fixed to the end face of the blind hole 431 by a screw 7. The elastic element 5 is set as a spring. One end of the elastic element 5 is connected and fixed to the washer 51 by welding. After the washer 51 is connected to the blind hole 431, it is ensured that the elastic element 5 is connected and fixed to the blind hole 431.

[0034] The working principle of this utility model is described as follows:

[0035] By wrapping the cable around the fixing member 4, or by using a copper lug to fit the fixing member 4, and then inserting the fixing member 4 into the connector 3, the fixing part 41 enters along the direction of the slide groove 31. At this time, simply rotate the fixing member 4 to allow the fixing part 41 to enter the fixing groove 32 and complete the connection.

[0036] In addition, the elastic element 5 applies force to increase the friction between the fixing part 41 and the fixing groove 32, preventing the fixing part 4 from being displaced by external force. At the same time, the elastic element 5 also makes the cable or copper lug pressed tightly onto the copper busbar 2 by the fixing part 4, ensuring stable wiring.

[0037] However, due to the presence of cables or copper lugs, the distance between the fixing part 4 and the copper busbar 2 increases. The adjustable fixing part 41 can be inserted into the fixing groove 32 at different heights to accommodate cables and copper lugs of different thicknesses. This design overcomes the defects of traditional technology, improves wiring efficiency, and reduces workload.

[0038] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
