In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0029] Example 1:

[0030] This embodiment provides a fuse-type switch, including:

[0031] Base 1, with a storage chamber inside.

[0032] Cover 2 is mounted on base 1 to cover the storage chamber. Cover 2 is provided with a first fixing groove 21 and a second fixing groove 22.

[0033] Two limiting plates 3 are respectively installed on the first fixing groove 21 and the second fixing groove 22, and each of the two limiting plates 3 has a limiting groove 31.

[0034] The buckle 4 is swayably installed in the first fixing groove 21 and located between the limiting plate 3 and the first fixing groove 21. The buckle 4 is provided with a connecting hole 41.

[0035] The fuse 5 has a first connector 51 and a second connector 52 respectively provided at both ends along the X direction. The first connector 51 and the second connector 52 are both located in the limiting groove 31 and abut against the limiting plate 3 along the Z direction.

[0036] The first connector 51 is disposed through the connecting hole 41, and the connecting hole 41 restricts the movement of the first connector 51 in the X direction.

[0037] In this technical solution, the fuse-type switch consists of a base 1, a cover 2, a fuse 5, a latch 4, and a limiting plate 3. Three rows of storage chambers are formed along the Y direction on the base 1. Each storage chamber includes an arc-extinguishing groove, a placement groove, and a wiring groove arranged sequentially along the X direction. The placement groove is used to place the fuse 5. The cover 2 is installed on the base 1 to seal the storage chambers. A first fixing groove 21 and a second fixing groove 22 are provided on the cover 2 at positions corresponding to the storage chambers. The space between the first fixing groove 21 and the second fixing groove 22 is used to install and place the fuse 5, so that when the cover 2 is installed on the base 1, the fuse 5 can be located within the placement groove of the base 1.

[0038] The fuse 5 is installed and fixed on the faceplate 2 by setting a limiting plate 3 and a buckle 4. The two limiting plates 3 are respectively installed on the first fixing groove 21 and the second fixing groove 22. The buckle 4 is made of plastic and has a certain elasticity. The buckle 4 is installed between the first fixing groove 21 and the limiting plate 3 and can swing along the Z direction.

[0039] During installation, the operator first presses the latch 4 to increase the gap between the latch 4 and the limiting plate 3. Then, along the X-axis, the first connector 51 and the second connector 52 on the fuse 5 are pushed into the limiting grooves 31 of the two limiting plates 3, respectively. The first connector 51 and the second connector 52 have the same structure. The two limiting plates 3 respectively restrict the first connector 51 in the Z and Y directions and restrict the second connector 52 in the Z and Y directions, thereby achieving the limiting installation of the fuse 5 on the cover 2 along the Z and Y directions. Next, the latch 4 is released to reset the latch 4. The first connector 51 will be inserted into the connecting hole 41 of the latch 4. The connecting hole 41 of the latch 4 limits the first connector 51 along the X-axis, thereby restricting the fuse 5 in the X-axis and thus achieving the fixed installation of the fuse 5 on the cover 2.

[0040] In summary, by installing a limiting plate 3 with a limiting groove 31 and a buckle 4 with a connecting hole 41 on the first fixing groove 21 of the cover 2, the first connecting member 51 on the fuse 5 is limited in the X, Y, and Z directions. By installing a limiting plate 3 with a limiting groove 31 on the second fixing groove 22 of the cover 2, the second connecting member 52 on the fuse 5 is limited in the Y and Z directions. Thus, the fuse 5 is fixedly installed on the cover 2. Then, the cover 2 is installed on the base 1, so that the fuse 5 is located inside the base 1. The operation is simple, the disassembly and assembly are convenient, and it is more convenient and practical.

[0044] Fixing part 42 is disposed on the first fixing groove 21;

[0045] The deformable part 43 is disposed on the limiting plate 3 in a swingable manner along the Z direction and is located below the limiting plate 3 along the Z direction.

[0046] The connecting hole 41 is provided on the deformable part 43.

[0047] In this technical solution, the buckle 4 has a "T" shaped structure, consisting of a fixing part 42 and a deformable part 43. The operator presses the deformable part 43 to increase the gap between the deformable part 43 and the limiting plate 3, thereby ensuring that the first connecting piece 51 can move between the deformable part 43 and the limiting plate 3. When the deformable part 43 is reset, the connecting piece will be inserted into the connecting hole 41 of the deformable part 43, so that the deformable part 43 can limit the first connecting piece 51 in the X direction, preventing the fuse 5 from moving in the X direction and detaching from the cover 2.

[0048] Furthermore, a touch block 44 is provided on the deformable part 43. By providing the touch block 44, it is convenient for the operator to press the deformable part 43 to cause it to deform, which is highly practical.

[0049] Example 3:

[0050] This embodiment provides a fuse-type switch, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0051] Furthermore, the two limiting plates 3 are respectively installed on the first fixing groove 21 and the second fixing groove 22 by setting fasteners.

[0052] In this technical solution, both limiting plates 3 are installed on the first fixing groove 21 and the second fixing groove 22 respectively by setting screws. Through this structural design, the limiting plate 3 and the cover 2 are detachably connected, which facilitates the maintenance and replacement of the limiting plate 3, avoids the need to replace the entire cover 2 due to damage to the limiting plate 3, effectively reduces maintenance costs and improves economic efficiency.

The groove 24 is connected to the mounting rod 12, and the cover 2 is rotated around the mounting rod 12, so that the connecting head 23 is embedded in the mounting groove 11 of the base 1. At the same time, the cover 2 can also be placed on the base 1 to achieve closure.

[0056] Furthermore, the connecting head 23 also includes a "C"-shaped groove 25, and a limiting rod 13 is provided in the mounting groove 11, with the limiting rod 13 located within the "C"-shaped groove 25. Through this structural design, when the face cover 2 is opened, the limiting rod 13 engages with the "C"-shaped groove 25 on the connecting head 23, preventing the connecting head 23 from directly detaching from the mounting groove 11, thus facilitating the subsequent closing of the face cover 2. When it is necessary to disassemble the face cover 2, the groove 24 on the connecting head 23 is separated from the mounting rod 12, and then the connecting head 23 is disengaged from the limiting rod 13, thereby enabling the face cover 2 to be disassembled.
