For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] In one aspect of the embodiment of the present application, please refer to Figure 1 , a wiring module 100 is provided, a busbar is provided on one side of the wiring module 100 for connecting to a circuit breaker; a terminal assembly 104 is provided on the other side of the wiring module 100 for connecting to a busbar.

[0034] Among them, Figure 4 , Figure 5 As shown, the busbar includes at least an L-pole busbar 101, and on this basis, an N-pole busbar 102 arranged side by side with the L-pole busbar 101 can also be included to be connected to the L-pole and N-pole of the circuit breaker respectively, as shown in FIG. Figure 1 to Figure 3 shown.

[0035] The wiring module 100 is a modular unit that meets the requirements corresponding to the width of the circuit breaker; a plurality of such wiring modules 100 are divided into two rows and arranged on both sides of the base, a circuit breaker is sandwiched between the two rows of wiring modules 100, a bus is arranged on the base, one side of the wiring module 100 is connected to the circuit breaker, and the other side is connected to the bus, so as to form an electrical component adapted to the circuit breaker and the base.

[0036] Specifically, the wiring module 100 includes a shell 10, and related components are arranged inside the shell 10. A busbar is arranged on one side of the shell 10, and the busbar is connected to the circuit breaker to form a loop between the wiring module 100 and the circuit breaker; at the same time, a terminal assembly 104 is also arranged on the other side of the shell 10, and the terminal assembly 104 is connected to the bus to form a loop between the wiring module 100 and the bus. The bus is arranged on the base, so that the circuit breaker can form a loop through the wiring module 100 and the base, and can be applied to the required scenario.

[0037] Due to the modular setting of the wiring module 100, multiple wiring modules 100 can be expanded on the base as needed. When the base and the circuit breaker are connected, the circuit breaker and the wiring module 100 can be freely disassembled and assembled. It has strong scalability and can be adapted according to different functions to flexibly meet the needs of different scenarios.

[0038] There is at least one terminal assembly 104. When the busbar has only the L-pole busbar 101, there is only one corresponding terminal assembly 104. The terminal assembly 104 is connected to the busbar, and the terminal assembly 104 is slidably connected to the housing 10. Figure 4 , Figure 5 shown.

[0039] When the busbar includes an L-pole busbar 101 and an N-pole busbar 102 , there are two terminal assemblies 104 , and the two terminal assemblies 104 are respectively connected to the busbar, and at least one terminal assembly 104 is slidably connected to the housing 10 .

[0040] When there are multiple terminal assemblies 104 , some of the terminal assemblies 104 are slidably connected to the housing 10 , and some of the terminal assemblies 104 are fixedly connected to the housing 10 .

[0041] like Figure 2 As shown, taking one terminal assembly 104 as being fixed and the other terminal assembly 104 as being slidingly arranged as an example, the fixedly arranged terminal is referred to as a fixed terminal 104b; the slidable terminal is referred to as a sliding terminal 104a, which, when sliding to different positions of the housing 10, can correspond to different phase sequences of the busbar respectively.

[0042] Of course, both terminal assemblies 104 may be slidably connected to the housing 10 to correspond to different phase sequences of the busbars, such as Figure 6 , Figure 7 shown. Figure 6 , Figure 7 The example shows the case where both the two terminal assemblies 104 are sliding terminals 104 a. When the two sliding terminals 104 a slide to different positions of the housing 10 , they can also correspond to different phase sequences of the busbar respectively.

[0043] Generally, the bus is provided with four phase sequences of A, B, C, and N, and the slidable terminal assembly 104 (sliding terminal 104a) can slide to four corresponding positions respectively, correspondingly connecting the A, B, C, and N phase bus respectively.

[0044] By setting the slidable terminal assembly 104, the corresponding phase sequence when the plug-in circuit breaker is connected to the distribution box can be adjusted arbitrarily, thereby ensuring the versatility and interchangeability of the plug-in circuit breaker to flexibly adapt to various distribution systems.

[0045] Specifically, a slide groove 11 is provided on the housing 10 , and a sliding protrusion is provided on the slidable terminal assembly 104 , so that the terminal assembly 104 can slide along the slide groove 11 relative to the housing 10 through the cooperation between the sliding protrusion and the slide groove 11 .

[0046] The sliding protrusion is engaged with the sliding groove 11 , so that the terminal assembly 104 can slide to different positions relative to the housing 10 .

[0047] Furthermore, when the terminal assembly 104 slides into position, in order to ensure that the terminal assembly 104 and the busbar can be firmly connected, the terminal assembly 104 needs to be locked to the position to prevent the terminal assembly 104 from sliding away and affecting the connection between the two. Therefore, a locking structure is provided on the terminal assembly 104, and a plurality of locking positions are provided on the housing 10. The plurality of locking positions correspond to different phase sequences respectively. When the terminal assembly 104 slides to the corresponding locking position, the locking structure locks the terminal assembly 104 in the locking position.

[0048] The locking structure enables the terminal assembly 104 to be locked in the locking position to lock with the locking position. The locking position corresponds to different phase sequences of the bus. At this time, the terminal assembly 104 is connected to the phase sequence corresponding to the bus at this position.

[0049] In one embodiment, Figure 2 , Figure 3 As shown, the locking position is a first slot 12 provided on the housing 10 , and the locking structure includes a locking protrusion 1042 that cooperates with the first slot 12 so that the terminal assembly 104 is locked in the first slot 12 .

[0050] The terminal assembly 104 slides along the slide groove 11 of the shell 10 through the sliding protrusion. When sliding to the locked position, the locking protrusion 1042 on the terminal assembly 104 is inserted into the first locking groove 12 of the shell 10 to lock the terminal assembly 104 in the first locking groove 12. At this time, the terminal assembly 104 can no longer slide, so that the terminal assembly 104 can be firmly connected to the phase sequence corresponding to the bus.

[0051] On this basis, the locking structure further includes a locking member disposed on the wiring module 100 , the locking protrusion 1042 is linked to the locking member, and the locking member is used to drive the locking protrusion 1042 to lock or unlock with the first locking slot 12 .

[0052] In one implementation, the locking member may be a rotating arm 1043 rotatably disposed on the terminal assembly 104 , and the latching protrusion 1042 is disposed on the rotating arm 1043 . The rotating arm 1043 is rotated to drive the latching protrusion 1042 and the first slot 12 to be locked or unlocked.

[0053] When the rotating arm 1043 is pressed to rotate, the latching protrusion 1042 can be driven to approach or move away from the first slot 12. When the latching protrusion 1042 moves toward the direction close to the first slot 12 and the latching protrusion 1042 extends into the first slot 12 and engages, the terminal assembly 104 can be locked in the first slot 12. When the terminal assembly 104 needs to be slid to other phase sequence positions, the rotating arm 1043 can be driven to rotate in the opposite direction to drive the latching protrusion 1042 away from the first slot 12, and the latching protrusion 1042 is disengaged from the first slot 12, thereby unlocking the latching protrusion 1042 and the first slot 12. At this time, the terminal assembly 104 can continue to slide along the slide groove 11 to the desired position.

[0054] The setting of the locking member drives the locking protrusion 1042 and the first locking groove 12 to lock or unlock, thereby realizing the locking or unlocking of the terminal assembly 104 and the locking position.

[0055] As mentioned above, the bus is provided with four phase sequences of A, B, C, and N. In order to correspond to these four phase sequences respectively, four locking positions are also provided on the housing 10. The terminal assembly 104 can slide to the four positions respectively to correspond to the four phase sequences respectively.

[0056] Please refer to Figure 3 As shown, the terminal assembly 104 includes a terminal base 1040 and a terminal cover 1041 that cooperate with each other. The terminal base 1040 and the terminal cover 1041 are respectively provided with sliding protrusions and locking structures for sliding and locking with the corresponding sides of the housing 10.

[0057] The housing 10 can be divided into an upper shell and a lower shell that are relatively buckled, and the upper shell and the lower shell are both provided with a slide groove 11, the terminal seat 1040 is slidably arranged with the lower shell, and the terminal cover 1041 is slidably arranged with the upper shell; similarly, locking positions are respectively arranged on the upper shell and the lower shell, and the terminal seat 1040 and the terminal cover 1041 are respectively provided with locking structures, and the terminal seat 1040 is locked in the locking position corresponding to the lower shell of the terminal through the locking structure, and the terminal cover 1041 is locked in the locking position corresponding to the upper shell through the locking structure. The specific setting of the locking structure refers to the above, and will not be repeated here.

[0058] In addition, when the terminal cover 1041 and the terminal base 1040 are matched, a second card slot 1040a is formed on the side of the terminal base 1040, and a buckle 1041a extending toward the second card slot 1040a is provided on the terminal cover 1041. The buckle 1041a and the second card slot 1040a are matched to make the terminal cover 1041 and the terminal base 1040 snap together.

[0059] For example, the terminal base 1040 is provided with second slots 1040a on both sides, and the terminal cover 1041 is formed with buckles 1041a on both sides, and the buckles 1041a extend toward the second slots 1040a, so that the terminal cover 1041 and the terminal base 1040 are engaged and connected. Such a configuration facilitates the assembly of the terminal base 1040 and the terminal cover 1041, and the terminal base 1040 and the terminal cover 1041 can be easily disassembled and assembled through the buckles 1041a.

[0060] like Figure 8 As shown, on the other hand, an embodiment of the present application further discloses a circuit breaker base, including a circuit breaker 201, a base 200, a bus and a wiring module 100 as described above, wherein the circuit breaker 201, the bus and the wiring module 100 are all arranged on the base 200, and one side of the wiring module 100 is connected to the circuit breaker 201, and the other side is connected to the bus.

[0061] Specifically, the wiring module 100 is connected to the circuit breaker 201 via the busbar, and the wiring module 100 is connected to the busbar via the terminal assembly 104. When the terminal assembly 104 is a slidable terminal assembly, it can be connected to the busbars of different phase sequences respectively to adjust the corresponding phase sequence when the circuit breaker base is connected to the distribution box.

[0062] Generally, there may be multiple circuit breakers 201 , wiring modules 100 , and busbars. The multiple wiring modules 100 are arranged in two rows on both sides of the base 200 , and the multiple circuit breakers 201 are arranged side by side between the two rows of wiring modules 100 .

[0063] In addition, a main control module is disposed below the circuit breaker 201 , and the circuit breaker 201 is disposed on the base 200 through the main control module.

[0064] In addition, a guide rail is provided at the bottom of the base 200 for connecting external devices. For example, the width of the guide rail is 35 mm, which is a standard guide rail, so that the circuit breaker base can be slidably connected to external devices such as a distribution box through the guide rail.
