DETAILED DESCRIPTION
[0026] First, if Figure 1 As shown, the circuit breakers commonly used in the prior art are large in size and relatively complex in structure, occupying a large installation space, thereby increasing the space inside or outside the whole device, which is contrary to the requirement in the semiconductor industry that the whole device has a smaller size.
[0027] Below, the specific implementation methods of the present application are described in detail with reference to the accompanying drawings.
[0028] like Figure 6 , 7 As shown, the present application provides a cover 100, which is used to accommodate a circuit breaker 10, and a toggle switch 11 is arranged on the circuit breaker 10. The cover 100 matches one side of the toggle switch 11 of the circuit breaker 10, and has a strip hole 120 that matches the toggle direction of the toggle switch 11. The length of the strip hole 120 allows the toggle switch 11 to be in a toggle position corresponding to its opening or closing. There is also a lock plate 200 that can be detachably assembled to the surface of the cover. When the lock plate 200 is assembled to the surface of the cover 100, it covers part of the strip hole 120, and one side of the lock plate 200 abuts against the toggle switch 11 to keep it in a closed toggle position.
[0029] like Figure 5As shown, the toggle switch 11 has an upper toggle position and a lower toggle position, the upper toggle position is an open toggle position, and the lower toggle position is a closed toggle position. Figure 7 , 9 As shown, the locking plate 200 covers a portion of the strip-shaped hole 120 from top to bottom.
[0030] In this embodiment, if Figure 2 , 3 As shown in FIG. 4 , the cover 100 is a sheet metal member having a protrusion 110, a strip hole 120 is arranged on the protrusion 110, and one end of the strip hole 120 is arranged at the edge of the protrusion 110. In addition, in other embodiments, the cover 100 can be other types of sheet metal members to adapt to different models of circuit breakers.
[0031] like Figure 2 As shown, a guide plate 130 is provided at the connection between the strip hole 120 and the lock plate 200. The guide plate 130 extends perpendicularly to the cover body 100 along the edge of the strip hole 120 toward the direction of the circuit breaker 10. A guide groove 131 is opened on the guide plate 130. The size of the guide groove 131 matches the thickness of the lock plate 200. The lock plate 200 can be inserted into the guide groove 131 from top to bottom, thereby achieving engagement with the cover body 100.
[0032] like Figure 2 As shown, a first fixing ring 140 and a second fixing ring 150 are further provided on the convex portion 110 of the cover body 100 . The first fixing ring 140 is provided with a first locking hole 141 , and the second fixing ring 150 is provided with a second locking hole 151 .
[0033] like Figure 2 As shown, a fixing hole 210 is provided on the locking plate 200 , and the locking plate 200 is sleeved on the first fixing ring 140 or the second fixing ring 150 through the fixing hole 210 .
[0034] like Figure 7 , 8 As shown in FIG. 9 , the embodiment provided in the present application also includes a lock 2 , which can pass through the first lock hole 141 or the second lock hole 151 , so as to fix the lock plate 200 on the first fixing ring 140 or the second fixing ring 150 .
[0035] like Figure 8 , 9 As shown, a notch 160 is formed on the cover 100 , and the notch 160 is used to expose the reset button 12 on the circuit breaker 10 .
[0036] In this embodiment, the reset button 12 is a general term and may include multiple buttons, not specifically referring to a reset button.
[0037] Next, the method for using the circuit breaker according to the embodiment of the present application is described.
[0038] When the entire device needs to be powered on through a circuit breaker:
[0039] First, open the lock 2 and remove the lock plate 200; then, turn the switch 11 upward to the upper position to put the circuit breaker 10 in the disconnected state; finally, put the lock plate 200 on the second fixing ring 150 and then use the lock 2 to fix the lock plate 200. Figure 6 , 8 As shown, the cover body involved in the embodiment of the present application puts the circuit breaker in an unlocked state.
[0040] When the entire device needs to be powered off using a circuit breaker:
[0041] First, open the lock 2 and remove the lock plate 200; then, turn the switch 11 downward to the lower position to close the circuit breaker 10; finally, put the lock plate 200 on the first fixing ring 140, so that the lock plate 200 is engaged with the bar hole 120 through the guide groove 131, and then use the lock 2 to fix the lock plate 200. Figure 7 , 9 As shown, the cover body involved in the embodiment of the present application puts the circuit breaker in a locked state.
[0042] In summary, the cover body involved in the embodiment of the present application adopts a simple mechanical structure. Compared with the prior art, the circuit breaker no longer uses the traditional rotary handle to control the toggle switch, which can avoid the problem of failure of the toggle switch due to aging or damage of the rotary handle, improve safety and stability, and can adapt to more application scenarios and higher safety requirements. In addition, the cover body involved in the embodiment of the present application reasonably optimizes the spatial layout of the electrical control box on the whole equipment, and does not cause major changes in the shape and appearance of the structure of the whole equipment. In addition, the cover body involved in the embodiment of the present application has a simple structure and low cost, thereby increasing the product competitiveness of the circuit breaker equipment and the whole equipment.
