[0004] The purpose of this invention is to provide an insulating cover for a fuse clip to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An insulating cover for a fuse clip includes an insulating cover body that is inserted into a metal part inside a switch cabinet through an opening on one side, and an insulating cover portion that is inserted into the opening to fix the metal part.

[0007] A vertical plate is fixedly installed in the center of the inner wall of the insulating cover on the side opposite to the opening, and a groove is formed between the two vertical plates;

[0008] An arc-shaped plate is fixedly provided at the end of the upright plate and abuts against the insulating cover, and the two arc-shaped plates make the port of the slot a constricted opening.

[0009] Preferably, the outer arc apexes of the two arc-shaped plates are arranged adjacent to each other.

[0010] Preferably, the insulating cover body is provided with a boss, and the slot is located on the boss;

[0011] The insulating cover is provided with a retaining plate arranged along the diagonal of a rectangle, and the top and bottom of the boss can be embedded between the four retaining plates.

[0012] Preferably, rectangular slots are provided on the side walls of the insulating cover on both sides, and tenons are fixedly provided on the side walls of the insulating cover to engage with the rectangular slots provided on the side walls of the insulating cover on both sides.

[0013] Preferably, the top and bottom of the insulating cover are provided with semi-circular grooves that communicate with the opening.

[0014] Preferably, the arc-shaped plate is an elastic copper mother.

[0015] In the above technical solution, the fuse clip insulation cover provided by this utility model has the following beneficial effects: the insulation cover is clipped onto the metal part inside the switch cabinet, and then the metal part is embedded in the slot. The arc-shaped plate made of elastic copper nut contacts the metal part to achieve electrical connection. Then, the insulation cover is embedded into the port of the insulation cover to seal it, and at the same time, the arc tops of the abutting arc-shaped plate approach each other for contact.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-3 As shown, a fuse clip insulating cover includes an insulating cover body 1 that is inserted into a metal part inside a switchgear through an opening on one side, and an insulating sealing cover part 2 that is inserted into the opening to fix the metal part. Specifically:

[0024] A vertical plate 3 is fixedly installed in the center of the inner wall of the insulating cover 1 on the side opposite to the open end, and a groove is formed between the two vertical plates 3. An arc-shaped plate 4 is fixedly installed at the end of the vertical plate 3 and abuts against the insulating cover 2. The two arc-shaped plates 4 make the port of the groove constricted, and are combined with Figure 2It can be seen that the outer arc apex of the two arc-shaped plates 4 mentioned above are arranged adjacently, that is, the gap between the outer arc apex is the same as the distance between the two arc apex.

[0025] Furthermore, a boss 11 is provided inside the insulating cover 1, and a slot is located on the boss 11. Because the insulating cover part 2 is provided with a retaining plate 21 arranged along the diagonal of a rectangle, when the insulating cover part 2 and the insulating cover 1 are combined to form a... Figure 1 When in the desired state, the top and bottom of the boss 11 can be inserted between the four locking plates 21 to achieve a secure hold.

[0026] Furthermore, in the above embodiment, rectangular slots 12 are respectively provided on the side walls of the insulating cover 1 on both sides, and tenons 22 are fixedly provided on the side walls of the insulating cover 2 to be inserted into the rectangular slots 12 respectively provided on the side walls of the insulating cover 1, so as to realize that the top and bottom of the boss 11 can be embedded between the four card plates 21 for positioning.

[0027] Furthermore, the top and bottom of the insulating cover 1 in the above embodiment are provided with semi-circular grooves 5 that communicate with the opening, and the semi-circular grooves 5 can be used to lock onto the metal parts inside the switch cabinet.

[0028] In the above technology, the insulating cover 1 is clipped onto the metal part inside the switch cabinet, and then the metal part is embedded in the slot. The arc-shaped plate 4 made of elastic copper nut contacts the metal part to achieve electrical connection. Then, the insulating cover 2 is embedded into the port of the insulating cover 1 to seal it, and at the same time, the arc tops of the arc-shaped plate 4 approach each other to make contact.

[0029] It should be noted that the insulating material of the insulating cover 1 and the insulating sealing part 2 in the above embodiments can be mica sheet or insulating rubber, or other insulating materials known to those skilled in the art.

[0030] Secondly, the aforementioned fixing and setting can adopt known connection methods such as bonding or integral molding, which will not be described in detail here.
