[0010] Preferably, the opposite side of the second groove is provided with a sliding groove that is interconnected with each other. The sliding groove is provided with a recessed groove, and the recessed groove is provided with a guide hole with a square structure. The entrance of the guide hole is provided with a countersunk hole.

[0011] Preferably, the inner walls of the first and second wire grooves are provided with cavities that fit the wires.

[0012] Preferably, the clamping assembly includes a clamping block, a guide rod, and a compression spring.

[0014] Beneficial effects:

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

[0016] This invention achieves primary clamping and fixing by placing the wire in the first groove and flipping the pressure plate, causing the clamping part to press the wire tightly into the first groove. Subsequently, the wire is guided along the expansion part, causing the clamping block to move away from the second groove and allowing the wire to pass through. After the compression spring releases its elasticity, it drives the clamping block to press the wire tightly into the second groove, increasing the friction between the wire and the second groove. The tightening part is guided inward by the cavity and contracts tightly against the surface of the wire, further increasing the friction between the wire and the clamping block. Multiple protrusions are used to enhance the friction effect, forming a secondary clamping and fixing. This structure effectively prevents the connection terminals from loosening due to frequent pulling of the wire during equipment maintenance, thereby improving the stability of the electrical connection and reducing the workload of secondary maintenance.

Detailed Implementation

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

Therefore, they should not be construed as limitations on this utility model.

[0029] In this embodiment of the utility model, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0030] Reference example Figures 1 to 8 A stable power metering box includes a box body 1. The bottom of the box body 1 is provided with a plurality of equally spaced protruding wiring portions 2. The wiring portions 2 and their front walls are provided with a first wire groove 21 for accommodating wires. The bottom of the box body 1 is provided with a second wire groove 11 and communicates with the first wire groove 21. One side of the wiring portion 2 is provided with a plurality of anti-retraction portions 22. The other side of the wiring portion 2 is provided with a rotatable pressure plate 3. The pressure plate 3 is pressed against any one of the anti-retraction portions 22. The pressure plate 3 is provided with a pressing portion 31 embedded in the first wire groove 21. The opposite side of the second wire groove 11 is provided with a pressing component 4 that can move horizontally.

[0031] By placing the wire in the first wire groove 21 and flipping the pressure plate 3, the clamping part 31 presses the wire into the first wire groove 21, achieving primary clamping and fixing. Subsequently, the wire is guided along the expansion part 415, causing the clamping block 41 to move away from the second wire groove 11 and accommodate the wire passing through. After the compression spring 43 releases its elastic force, it drives the clamping block 41 to press the wire into the second wire groove 11, increasing the friction between the wire and the second wire groove 11. The tightening part 412 is guided by the cavity 7 to shrink inward and fit tightly against the surface of the wire, further increasing the friction between the wire and the clamping block 41. Multiple protrusions 414 are used to enhance the friction effect, forming secondary clamping and fixing. The above structure can effectively prevent the connection terminals from loosening due to frequent pulling of the wire during equipment maintenance, thereby improving the stability of the electrical connection and reducing the workload of secondary maintenance.

[0032] It is worth mentioning that the housing 1 has a corresponding air switch 5 located above the wiring section 2;

[0033] It is worth mentioning that the wiring part 2 is provided with an inclined wire bundling part 23, and the first wire groove 21 is provided in the wire bundling part 23. The inclined wire bundling part 23 is positioned so that it faces the user's field of vision, making it convenient for the user to perform wire bundling operations.

[0034] It is worth mentioning that an energy storage part 32 extends from one side of the pressure plate 3, and a clamping part 33 extends from the energy storage part 32. The clamping part 33 is provided with a locking part 34. The anti-retraction part 22 is provided with inclined guide surfaces 6 in the direction towards the clamping part 33 and in the direction towards the anti-retraction part 22. The energy storage part 32 adopts an arched structure design to ensure that the locking part 34 and the side wall of the wiring part 2 are tightly abutted. When the locking part 34 moves along the direction of the anti-retraction part 22, the pressure part 31 can adjust the clamping position of the locking part 34 on the anti-retraction part 22 according to the wire diameter. The guide surface 6 improves the smoothness of the movement of the locking part 34. When it is necessary to disconnect the pressure plate 3 from the wiring part 2, the clamping part 33 can be pulled to make the locking part 34 disengage from the anti-retraction part 22, realizing quick disassembly, enhancing the convenience of operation, and ensuring structural stability and reliability of repeated use.

[0035] It is worth mentioning that opposite the second groove 11 is a sliding groove 12 that is interconnected. The sliding groove 12 is provided with a recess 13. The recess 13 is provided with a guide hole 14 with a square structure. The entrance of the guide hole 14 is provided with a countersunk hole 15, which allows the pressing block 41 to move. The recess 13 provides a space for the compression spring 43. The square structure of the guide hole 14 prevents the pressing block 41 from rotating during the movement. The countersunk hole 15 limits the movement stroke of the pressing block 41.

[0036] It is worth mentioning that the inner walls of the first wire groove 21 and the second wire groove 11 are provided with cavities 7 that fit the wire, and the cavities 7 increase the contact area with the wire.

[0037] It is worth mentioning that the clamping assembly 4 includes a clamping block 41, a guide rod 42, and a compression spring 43. The guide rod 42 is slidably disposed in the guide hole 14 and corresponds to the side wall of the guide hole 14. One end of the guide rod 42 is provided with a retaining ring 44 and is slidably disposed in the countersunk hole 15. The other end of the guide rod 42 is connected and fixed to the clamping block 41 by welding. The compression spring 43 is sleeved on the outer wall of the guide rod 42, and its two ends abut against the end face of the clamping block 41 and the countersunk groove 13, respectively. The retaining ring 44 is used in conjunction with the countersunk hole 15. The compression spring 43 resets the clamping block 41 and ensures that the clamping block 41 fits tightly with the cavity 7 of the second groove 11.

[0038] It is worth mentioning that the clamping block 41 is provided with a third wire groove 411 for accommodating the wire. The two sides of the third wire groove 411 are provided with inwardly retractable tightening parts 412. The outer wall of the tightening part 412 is provided with an inclined part 413, which abuts against the inner wall of the cavity 7. The side wall of the third wire groove 411 and the inner side wall of the tightening part 412 are provided with several equally spaced protrusions 414. The two ends of the third wire groove 411 and the tightening part 412 are provided with expansion parts 415. Under the action of the compression spring 43, the inclined part 413 is guided by the cavity 7 to cause the tightening part 412 to contract in the middle direction, closely fitting the outer wall surface of the wire. The protrusions 414 enhance the friction between the clamping block 41 and the wire. The wire gradually opens the gap between the clamping block 41 and the second wire groove 11 through the expansion part 415, so as to smoothly pass through. Both the clamping part 31 and the clamping block 41 are made of rubber, which has good elasticity and wear resistance, improving structural adaptability and long-term reliability.
