[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0024] according to Figure 1 , 2 As shown in , 3 and 4, a leakage protection low-voltage cabinet is proposed in this embodiment, including a cabinet body 1 and a cabinet door 2, the cabinet door 2 is rotatably connected to the cabinet body 1, a wiring board 3 is arranged in the cabinet body 1, and a leakage protector 4 is mounted on the wiring board 3;

[0025] The edge of the wiring board 3 is provided with a plurality of internal support structures, and the wiring board 3 is detachably connected to the cabinet 1 through the internal support structures; the leakage protector 4 and other types of electrical components are assembled on the wiring board 3 through screws and nuts, and the wiring board 3 is fixed in the cabinet 1 through the internal support structures. The detachable connection mode of the wiring board 3 makes it convenient for operators to completely remove the electrical components and connecting lines from the cabinet 1, and maintenance and repair are convenient and quick.

[0026] It should be noted that the internal support structure includes a clamping plate 6 arranged on the edge of the wiring board 3, a wire plate 8 is arranged on the side of the clamping plate 6 away from the wiring board 3, bolt supports are arranged on both sides of the wire plate 8, the wire plate 8 is fixedly connected to the clamping plate 6, and a wire groove 9 is opened on the side of the wire plate 8 facing the clamping plate 6, and the wire groove 9 extends toward the cabinet door 2. The bolt supports prop up the wiring board 3 from both sides of the wire plate 8, and fix the wiring board 3 inside the cabinet 1. When connecting the lines, the wires led out from the wiring board 3 can be inserted into the wire groove 9 opened on the wire plate 8. The wire plate 8 gathers the lines from the side of the wiring board 3 through the wire groove 9, ensuring that the lines inside the cabinet 1 are neat, which is convenient for operators to maintain.

[0027] It should be further explained that the bolt support includes a rubber pressure block 11 and an adjusting bolt 12 . The adjusting bolt 12 passes through the rubber pressure block 11 and is threadedly connected to the bolt seat 10 . The rubber pressure block 11 is rotatably connected to one end of the adjusting bolt 12 away from the clamping plate 6 .

[0028] The steps for using the bolt support are as follows:

[0029] After placing the wiring board 3 into the cabinet 1, the adjusting bolt 12 on the bolt seat 10 is rotated, and the adjusting bolt 12 will push the rubber pressing block 11 toward the inner wall of the cabinet 1. When the rubber pressing blocks 11 at the edges of the wiring board 3 are in contact with the inner wall of the cabinet 1 and pressure is applied to the cabinet 1, the rubber pressing blocks 11 will lock the wiring board 3 through the damping between the cabinets 1.

[0030] In order to prevent the wire harness introduced into the wire plate 8 from falling out of the wire groove 9, a plurality of baffles 13 are provided on the side of the wire groove 9 facing the clamping plate 6, and positioning screws 14 are installed at both ends of the baffle 13, and the positioning screws 14 are threadedly connected with screw holes 15 opened on the outside of the wire plate 8. The circuit passes through the wire groove 9, and the baffle 13 can prevent the circuit from falling out of the wire groove 9. When removing the baffle 13 from the wire plate 8, the positioning screws 14 at both ends of the baffle 13 can be screwed out from the corresponding screw holes 15.

[0031] The inner support structure is arranged at the edge of the wiring board 3. In order to achieve the best fixing effect, it is necessary to make certain adjustments to the positions of the inner support structures. Specifically, there are at least two clamping plates 6 on both sides of the wiring board 3, and at least two clamping plates 6 are arranged at the lower end of the wiring board 3. The clamping plates 6 at the lower end of the wiring board 3 can support the wiring board 3 through the bolt support members, thereby reducing the burden of the bolt support members on both sides of the wiring board 3 and improving the stability of the wiring board 3 after installation.

[0032] In order to facilitate the personnel to replace the inner support structure, the clamping plate 6 is fixed to the wiring board 3 in a detachable connection manner. A better implementation is that the clamping plate 6 is equipped with a plurality of fixing screws 7, which pass through the clamping plate 6 and are threadedly connected with the bolt grooves provided at the edge of the wiring board 3. When removing the clamping plate 6 from the wiring board 3, the fixing screws 7 on the clamping plate 6 can be unscrewed from the corresponding bolt grooves.

[0033] See also Figure 2 A better implementation is that a plurality of supporting legs 5 are provided at the lower end of the cabinet 1, the supporting legs 5 are fixedly connected to the cabinet 1, and a rubber pad is provided at the lower end of the supporting legs 5, which plays an anti-slip role. The supporting legs 5 at the lower end of the cabinet 1 are used to support the cabinet 1, separate the cabinet 1 from the ground, ensure ventilation and heat dissipation at the bottom of the cabinet 1, and also prevent water from accumulating on the ground and wetting the bottom of the cabinet 1.

[0034] See also Figure 5Another better implementation is that a plurality of adjustment feet are provided at the lower end of the cabinet 1, and the adjustment feet include a support column 51 and a rubber seat 52. The support column 51 is fixedly connected to the lower end of the cabinet 1, and a threaded sleeve 54 is provided at the upper end of the rubber seat 52. The threaded sleeve 54 is fixedly connected to the rubber seat 52, and the rubber seat 52 is sleeved on the lower end of the support column 51 and is threadedly connected to a threaded surface 53 opened at the lower end of the support column 51.

[0035] Different from the support leg 5, the support column 51 and the rubber seat 52 are fixed by means of threaded connection. The advantage of such a design is that when the rubber seat 52 is removed from the lower end of the support column 51 for replacement, it is only necessary to lift the cabinet 1 slightly upwards, then rotate the rubber seat 52, and unscrew the threaded sleeve 54 from the lower end of the support column 51. Disassembly and replacement are quick and convenient, and by rotating the threaded sleeve 54 to change the rotational position of the threaded sleeve 54, the support height of the entire cabinet 1 can be fine-tuned, which has higher flexibility.

[0036] How this application works:

[0037] The leakage protector 4 and other types of electrical components are assembled on the wiring board 3 by screws and nuts, and the wiring board 3 is fixed in the cabinet 1 by the internal support structure. The detachable connection mode of the wiring board 3 makes it convenient for operators to remove the electrical components and connecting lines from the cabinet 1;

[0038] The bolt support members prop up the wiring board 3 from both sides of the wire board 8, and fix the wiring board 3 inside the cabinet 1. When connecting the lines, the wires led out from the wiring board 3 can pass into the wire grooves 9 opened on the wire board 8. The wire board 8 gathers the lines from the sides of the wiring board 3 through the wire grooves 9, ensuring that the lines inside the cabinet 1 are neat and tidy, and maintenance and repair are convenient and quick.
