[0002] The cable distribution box is used for cable branching. The main functions of the cable distribution box are to tap or transfer cables, mainly playing the roles of cable tapping and cable transferring. When a power distribution line is relatively long, if many branch cables are selected for power transmission, a lot of cables will be wasted. Therefore, when power is transmitted from the outgoing line to the electrical load, usually a main large cable is selected for the outgoing line at the time of outgoing, and then when approaching the load, a cable distribution box is used to branch the main cable, dividing the main cable into many branch cables, and the branch cables are connected to the load.

[0003] Currently, there are multiple copper bars in the cable distribution box, and multiple fastening bolts are provided on the copper bars. Conventionally, the branch cable is usually wound around the rod portion of the branch bolt, and then the branch cable is fixed to the copper bar through a nut. This installation method is not only cumbersome but also time-consuming. Therefore, the applicant has made a beneficial design and found a solution to the above problems. The technical solution to be introduced below was generated under this background. Summary of the Invention

A liftable fixing plate 5 is provided on the guide rod 4. A spring 6 is provided on the guide rod 4 and acts on the fixing plate 5. The fixing plate 5 is provided with a first through hole 51. The first through hole 51 is provided with support blocks 52 arranged in a fork shape. Inclined surfaces 53 are provided on both sides of the support block 52. The plug pin 3 is provided with a hollow column 31 and passes through the mounting hole 21. A relief through hole 32 is provided at the end face of the hollow column 31. The relief through hole 32 is inserted into the support block 52, so that the relief through hole 32 expands to both sides, and the plug pin 3 is connected and fixed to the fixing plate 5;

[0028] It is worth mentioning that a chute 34 is provided on the outer wall of the hollow column 31, and a chamfer 35 is provided at the entrance of the relief through hole 32. The chute 34 is used in cooperation with the guide block 22, and the chamfer 35 facilitates the support block 52 to enter the relief through hole 32;

[0029] It is worth mentioning that the mounting hole 21 is provided with a guide block 22 and is arranged in the chute 34. The mounting hole 21 is evenly distributed with a number of through holes 23 around a dot. One end of the through hole 23 is provided with a threaded hole 24. The guide block 22 plays an anti-misalignment role, making the relief through hole 32 and the support block 52 on the same center line. The through hole 23 is for the guide rod 4 to pass through, and the threaded hole 24 is used in cooperation with the threaded portion 42;

[0030] It is worth mentioning that the bolt 3 is provided with a pull ring 33, and the pull ring 33 facilitates the bolt 3 to disengage from the fixing plate 5;

[0031] It is worth mentioning that the other end of the guide rod 4 is provided with a threaded portion 42 and is threadedly connected to the threaded hole 24. The threaded portion 42 prevents the guide rod 4 from disengaging from the copper busbar 2;

[0032] It is worth mentioning that the fixing plate 5 is provided with a second through hole 54 for the guide rod 4 to slide through. The second through hole 54 is provided with a limiting post 55. The spring 6 is arranged on the outer wall of the limiting post 55. Both sides of the fixing plate 5 are provided with grips 56 and are arranged on both sides of the copper busbar 2. The limiting post 55 not only plays a role in protecting the spring 6 but also prevents the fixing plate 5 from rising too far.

[0033] Now, the working principle of the present utility model is described as follows:

[0034] By winding the cable around the hollow column 31, it is only necessary to pass the hollow column 31 through the mounting hole 21, insert the relief through hole 32 into the support block 52. The inclined block expands the relief through hole 32 outward on both sides, thereby increasing the friction between the hollow column 31 and the fixing plate 5, and fixing the connection between the hollow column 31 and the fixing plate 5. Continuously apply a downward pressure to the bolt 3 to tightly press the cable against the copper busbar 2. At the same time, apply an upward force through the grip 56 to shorten the distance between the fixing plate 5 and the bolt 3, further strengthening the connection stability between the hollow column 31 and the fixing plate 5. The spring 6 releases a force to the fixing plate 5 to strengthen the connection stability between the cable and the copper busbar 2, and complete the connection and fixation of the cable and the copper busbar 2;

[0035] When it is necessary to separate the connection between the cable and the copper busbar 2, pull the bolt 3 upward through the pull ring 33. The fixing plate 5 gradually rises with the bolt 3 until the limiting post 55 abuts against the copper busbar 2. Then, the relief through hole 32 will gradually disengage from the support block 52. When the relief through hole 32 completely disengages from the support block 52, the spring 6 releases its elastic force to the fixing plate 5, causing the fixing plate 5 to abut against the baffle, and completing the separation operation steps of the cable.

[0036] Through the above design, the product can achieve the advantages of improving the wiring efficiency and connection stability.
