[0033] Reference Figure 1 , Figure 2 as well as Figure 3 As shown, the embodiment of the present application provides a circuit breaker connection structure, including a circuit breaker base 100 and a plurality of circuit breakers 115 arranged in sequence on the circuit breaker base 100; a clamping assembly 101 is arranged on the circuit breaker base 100, and the clamping assembly 101 includes a plurality of clamping grooves formed along the arrangement direction of the circuit breakers 115; a control plug 102 is arranged in the clamping groove, and a control interface 103 correspondingly plugged with the control plug 102 is arranged on the circuit breaker 115; the plurality of circuit breakers 115 are correspondingly plugged into the plurality of clamping grooves and the control interface 103 is connected to the control plug 102.

[0034] Reference Figure 2 and Figure 3As shown, as an optional implementation, the control interface 103 is provided with a current signal line and a voltage signal line that can be connected to the control plug 102.

[0035] Reference Figure 1 , Figure 2 as well as Figure 3 As shown, an embodiment of the present application provides a circuit breaker connection structure, including a circuit breaker base 100 and a plurality of circuit breakers 115 arranged in sequence on the circuit breaker base 100; a clamping assembly 101 is arranged on the circuit breaker base 100, and the clamping assembly 101 includes a plurality of clamping grooves formed along the arrangement direction of the circuit breakers 115; an incoming line connector 104 and an outgoing line connector 105 are arranged in the clamping groove, and an incoming line terminal 106 for connecting to the incoming line connector 104 and an outgoing line terminal 107 for connecting to the outgoing line connector 105 are arranged on the circuit breaker 115; and a plurality of circuit breakers 115 are correspondingly plugged into the plurality of clamping grooves perpendicular to the clamping grooves and connect the incoming line and the outgoing line.

[0036] Conventional technology usually sets the circuit breaker 115 in the electrical switch cabinet by bolts alone. When a fault occurs and the staff needs to repair the circuit breaker 115, they need to remove the bolts fixing the circuit breaker 115 before removing the circuit breaker 115. Therefore, it is inconvenient for the staff to repair the circuit breaker 115. The circuit breaker 115 provided in the embodiment of the present application fixes multiple circuit breakers 115 respectively through multiple clamping grooves, so that the circuit breaker 115 can be quickly connected to the circuit breaker base 100 through the clamping groove, and the circuit breaker 115 can be quickly pulled out from the clamping groove when maintenance is required. The present application sets an incoming line connector 104 and an outgoing line connector 105 on the clamping groove, and the circuit breaker 115 is provided with an incoming line terminal 106 for connecting to the incoming line connector 104 and an outgoing line terminal 107 for connecting to the outgoing line connector 105. When the staff inserts the circuit breaker 115, the incoming connection piece 104 is combined with the incoming terminal 106 and the outgoing connection piece 105 is combined with the outgoing terminal 107. When the staff unplugs the circuit breaker 115, the incoming connection piece 104 is separated from the incoming terminal 106 and the outgoing connection piece 105 is separated from the outgoing terminal 107, so that the circuit breaker 115 can be completely separated from the circuit breaker base 100. Therefore, when a fault occurs, the circuit breaker 115 provided in the embodiment of the present application is convenient for the staff to perform maintenance work, which is conducive to improving the maintenance efficiency.

[0037] Since multiple circuit breakers 115 are usually fixedly installed in the electrical switch cabinet in the prior art to protect the system circuit, and when a fault occurs, the circuit breaker 115 cannot be quickly disassembled, which is inconvenient for the staff to inspect and replace. For this reason, the present application provides a circuit breaker 115, including a circuit breaker base 100 and multiple circuit breakers 115 arranged in sequence on the circuit breaker base 100; and by setting a clamping groove on the circuit breaker base 100, the circuit breaker 115 can be connected to the circuit breaker base 100 by plugging. When the staff needs to inspect and replace the circuit breaker 115, the staff can quickly and directly unplug the circuit breaker 115, so that the incoming line connector 104 is separated from the incoming line terminal 106, and the outgoing line connector 105 is separated from the outgoing line terminal 107, so as to perform safe inspection. The circuit breaker 115 can be quickly inserted when installing the circuit breaker 115. Therefore, the present application can facilitate the staff to inspect and repair the circuit breaker 115, can improve the inspection and repair efficiency, can greatly reduce the adverse effects caused by the failure of the circuit breaker 115, and ensure that the power supply can be quickly restored after the failure.

[0038] Reference Figure 1 As shown, as an implementable method, the clamping groove includes two clamping plates 108 correspondingly arranged on both sides of the length direction of the circuit breaker base 100; a limiting rib 109 arranged perpendicular to the length direction of the circuit breaker base 100 is correspondingly arranged between the two clamping plates 108; the clamping plates 108 and the limiting rib 109 are both perpendicular to the plane where the circuit breaker base 100 is located; the two ends of the circuit breaker 115 perpendicular to the length direction of the circuit breaker base 100 are respectively in contact with the clamping plates 108, and the two ends of the circuit breaker 115 along the length direction of the circuit breaker base 100 are respectively in contact with the limiting rib 109. The embodiment of the present application discloses a specific setting method of the clamping groove, including two clamping plates 108 correspondingly arranged on both sides of the length direction of the circuit breaker base 100, and the two clamping plates 108 are used to clamp the two ends of the circuit breaker 115. Furthermore, a limiting rib 109 is correspondingly provided between the two clamping plates 108 and is arranged along a length direction perpendicular to the circuit breaker base 100. The limiting rib 109 is used to clamp the circuit breaker 115 again, and the circuit breaker 115 is fixed by the clamping plates 108 and the limiting rib 109 to avoid loosening of the circuit breaker 115 after being inserted into the clamping slot, which is conducive to ensuring a stable connection of the circuit breaker 115.

There are two groups of first clamping grooves 110 with different heights, and they are respectively located on two corresponding side surfaces of the circuit breaker 115. The two groups of first clamping grooves 110 with different heights can play a foolproof role, avoid the situation where the circuit breaker is installed in the wrong direction, and facilitate the rapid installation of the circuit breaker.

[0040] Furthermore, in the embodiment of the present application, a first card slot 110 is provided on the circuit breaker 115. The circuit breaker 115 in the embodiment of the present application is connected to the limiting rib 109 via the first card slot 110. The limiting rib 109 can be inserted into the first card slot 110, and the stability of the circuit breaker 115 after being inserted into the card slot can be improved.

[0041] Reference Figure 1 As shown, as an implementable method, the two clamping plates 108 are of different heights. In the embodiment of the present application, the two clamping plates 108 are set to different heights so that the circuit breaker 115 can be easily inserted into the clamping slot. When inserting the circuit breaker 115, the circuit breaker 115 can be tilted toward the lower clamping plate 108 to facilitate the circuit breaker 115 to enter the clamping slot smoothly. Similarly, when the circuit breaker 115 needs to be pulled out, the circuit breaker 115 can still be tilted toward the lower clamping plate 108 so that the circuit breaker 115 can be quickly pulled out. Therefore, the embodiment of the present application can prevent the circuit breaker 115 from getting stuck, and facilitates the quick plugging and unplugging of the circuit breaker 115.

[0042] Reference Figure 2 As shown, as an implementable method, the two ends of the circuit breaker 115 that contact the clamping plate 108 are provided with unlocking members 111; the clamping plate 108 is provided with a second clamping groove 112 that cooperates with the unlocking member 111. The unlocking member 111 is arranged inside the circuit breaker 115, and one end passes through the circuit breaker 115 and cooperates with the second clamping groove 112 to achieve locking of the circuit breaker in the open state. By setting the unlocking member 111, when installing the circuit breaker, it is possible to prevent the handle from closing the circuit breaker by mistake. When the circuit breaker 115 is installed on the base, the unlocking member 111 can lock the operating mechanism to keep the circuit breaker 115 in the open state. After the installation is completed, the locked state of the circuit breaker is released.

The embodiment of the present application discloses the specific arrangement positions of the incoming line connector 104 and the outgoing line connector 105, specifically, the incoming line connector 104 and the outgoing line connector 105 are arranged at the two ends of the contact surface between the circuit breaker 115 and the circuit breaker base 100. It should be noted that the incoming line terminal 106 and the outgoing line terminal 107 can also be arranged on the contact surface between the circuit breaker 115 and the clamping plate 108, and the corresponding incoming line connector 104 and the outgoing line connector 105 are arranged on the inner side surface of the clamping plate 108. After the circuit breaker 115 is inserted into the clamping slot, the incoming line terminal 106 and the outgoing line terminal 107 on the circuit breaker 115 are connected to the incoming line connector 104 and the outgoing line connector on the clamping plate 108 correspondingly.
