Technical Field

[0001] This utility model relates to the technical field of switches, and in particular to a modular low-voltage direct-acting fast switch. Background Technology

[0002] A switch is an electrical component used to control the on / off state of a circuit. It is widely used in various scenarios such as power systems, electronic equipment, and household appliances. Its core function is to control the current and voltage in the circuit by changing its own conduction state. In the use of low-voltage circuits, direct-acting fast switches are often used for control.

[0003] When using direct-acting fast switches to control low-voltage circuits, traditional direct-acting fast switches have poor resistance to external contaminants such as dust, moisture, and oil. These external contaminants will accelerate the wear on the surface of the direct-acting fast switch, which will easily lead to poor contact inside. This requires relevant personnel to carry out regular maintenance. Once the switch is damaged, it must be completely disassembled and replaced, which not only consumes a lot of time, but also affects the normal use of the switch. Utility Model Content

Detailed Implementation

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] A modular low-voltage direct-acting fast switch according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, a modular low-voltage direct-acting fast switch according to an embodiment of the present invention includes: a mounting bracket 1, a switch 2, and a protective mechanism 3.

[0023] The switch 2 is mounted on the mounting bracket 1, and the protective mechanism 3 includes a first protective shell 31, a connecting block 32, a second protective shell 34, a telescopic shell 35, a mounting component 36, and a fixing component 37.

[0024] The first protective shell 31 is disposed outside the switch 2, the connecting block 32 is disposed on the first protective shell 31, the second protective shell 34 is disposed on the side wall of the mounting bracket 1, the telescopic shell 35 is disposed on the outer wall of the first protective shell 31, the mounting component 36 is disposed on the connecting block 32, the fixing component 37 is disposed on the telescopic shell 35, and the outer wall of the first protective shell 31 is provided with a telescopic plate 33, and the side wall of the telescopic plate 33 is connected to the first protective shell 31.

[0025] It should be noted that the direct-acting quick switch 2 adopts a modular design. When a module is worn or malfunctions, there is no need to replace the entire switch 2. Only the corresponding module needs to be disassembled to complete the repair, thereby reducing the troubleshooting time.

[0026] Specifically, when using the direct-acting quick switch 2, the first protective shell 31 and the second protective shell 34 are pulled to both sides according to the size of the direct-acting quick switch 2 so that the space between the first protective shell 31 and the second protective shell 34 matches the direct-acting quick switch 2. Then, the first protective shell 31 and the second protective shell 34 are installed on the mounting bracket 1. At this time, the telescopic plate 33 will contact the top of the switch 2. At the same time, the telescopic plate 33 and the telescopic shell 35 provide enough space for cable installation. The telescopic shell 35 prevents external contaminants from contacting the surface of the switch 2, thereby improving the efficiency of the switch 2. At the same time, when it is necessary to use the switch 2 to control the low-voltage circuit, the switch 2 can be exposed and operated by pulling the telescopic shell 35.

[0027] In one embodiment of this application, such as Figure 3 As shown, the mounting assembly 36 includes a connecting rod 362, a latch 363, a lever 364, and a spring 365.

[0028] The connecting block 32 has a first mounting groove 361. The connecting rod 362 passes through the connecting block 32 and is connected to the bolt 363. The lever 364 is connected to the other end of the connecting rod 362. The spring 365 is sleeved on the outside of the connecting rod 362, and the two ends of the spring 365 are connected to the bolt 363 and the inner wall of the first mounting groove 361, respectively. The lever 364 is provided with a pull ring 366.

[0029] Specifically, when the first protective shell 31 and the second protective shell 34 are installed on the mounting bracket 1, the gaps between the two connecting blocks 32 installed on the outer sides of the first protective shell 31 and the second protective shell 34 are aligned with the mounting bracket 1 and inserted. At this time, the mounting bracket 1 will first contact the latch 363 and squeeze the latch 363 into the first mounting groove 361. When the mounting bracket 1 contacts the switch 2, the latch 363 will be ejected to the groove behind the mounting bracket 1 under the action of the spring 365, thereby installing the first protective shell 31 and the second protective shell 34 onto the mounting bracket 1.

[0030] In one embodiment of this application, such as Figure 4 As shown, the fixing component 37 includes a connecting plate 373, a fixing post 375, a fixing plate 377, a sliding groove 378, and a slider 379.

[0031] The telescopic shell 35 has a second mounting groove 371, the first protective shell 31 has a limit groove 372, the connecting plate 373 is pivotally connected to the inner wall of the second mounting groove 371, the second mounting groove 371 has a fixing groove 374, the fixing post 375 is disposed in the second mounting groove 371, the inner wall of the second mounting groove 371 has a connecting hole 376, the fixing plate 377 is disposed in the connecting hole 376, the inner wall of the connecting hole 376 has a sliding groove 378, and the slider 379 is disposed on the fixing plate 377.

[0032] Specifically, when using the telescopic shell 35 to protect the switch 2, the telescopic shell 35 is pulled so that one side of the telescopic shell 35 moves from the first protective shell 31 to the second protective shell 34. Then, the connecting plate 373 is folded so that the connecting plate 373 is inserted into the limiting groove 372, and the fixing post 375 in the limiting groove 372 is inserted into the fixing groove 374 on the connecting plate 373. Then, the fixing plate 377 is pulled out from the connecting hole 376, and the connecting plate 373 is fixed in the limiting groove 372, thereby fixing the telescopic shell 35.

[0033] Working principle: When using the direct-acting quick switch 2, the first protective shell 31 and the second protective shell 34 are pulled to both sides according to the size of the direct-acting quick switch 2 so that the space between the first protective shell 31 and the second protective shell 34 matches the direct-acting quick switch 2. Then, the first protective shell 31 and the second protective shell 34 are installed on the mounting bracket 1. At this time, the telescopic plate 33 will contact the top of the switch 2. At the same time, the telescopic plate 33 and the telescopic shell 35 provide enough space for cable installation. When the switch 2 needs to be used, the switch 2 can be exposed by pulling the telescopic shell 35 to open and close it. When installing the first protective shell 31 and the second protective shell 34 onto the mounting bracket 1, the gap between the two connecting blocks 32 installed on the outside of the first protective shell 31 and the second protective shell 34 is aligned with the mounting bracket 1 and inserted. When the mounting bracket 1 contacts the latch 363, it presses the latch 363 into the first mounting groove 361. When the mounting bracket 1 contacts the switch 2, the latch 363 will pop out to the groove behind the mounting bracket 1 under the action of the spring 365, thereby installing the first protective shell 31 and the second protective shell 34 onto the mounting bracket 1. When the telescopic shell 35 is used to protect the switch 2, the telescopic shell 35 is pulled so that one side of the telescopic shell 35 moves from the first protective shell 31 to the second protective shell 34. Then the connecting plate 373 is folded so that the connecting plate 373 is inserted into the limiting groove 372, and the fixing post 375 in the limiting groove 372 is inserted into the fixing groove 374 on the connecting plate 373. Then the fixing plate 377 is pulled out from the connecting hole 376, and the connecting plate 373 is fixed in the limiting groove 372, thereby fixing the telescopic shell 35.

[0034] In summary, by setting up the telescopic housing 35, the direct-acting quick switch 2 can be used normally without removing the first protective housing 31 and the second protective housing 34, while ensuring that the direct-acting quick switch 2 is not affected by external contaminants during use.
