DETAILED DESCRIPTION
[0037] The following is a further description of the specific implementation of the accessory module of the present invention in conjunction with the embodiments given in the accompanying drawings. The accessory module of the present invention is not limited to the description of the following embodiments.
[0038] The circuit breaker includes a circuit breaker body, which includes a shell. The shell is rotatably equipped with a handle assembly 21. An operating system 22 is arranged in the shell. The operating system 22 is linked to the handle assembly 21. The tripping system cooperates with the operating system 22 to trigger the operating system 22 to trip. One or more contact units are arranged in the shell. Each contact unit includes a pair of terminals and a contact system. The pair of terminals are arranged at intervals. The contact system is arranged between the pair of terminals. The contact system includes moving contacts and stationary contacts that cooperate with each other. The moving contacts and the stationary contacts are electrically connected to adjacent terminals respectively. The moving contact of at least one contact unit is linked to the operating system 22. The handle assembly 21 is operated to make the operating system 22 drive the moving contact to rotate in a direction close to or away from the stationary contact, thereby connecting or disconnecting the main line of each contact unit. The moving contacts of two adjacent contact units are linked to each other, so that the circuit breaker body can achieve synchronous closing and opening.
[0039] A tripping system is also provided in the housing, and the tripping system cooperates with the operating system 22 to trigger the tripping of the operating system 22. The tripping rotation of the operating system 22 drives the moving contact to rotate in a direction away from the static contact. Specifically, the tripping system includes a control circuit board and a mutual inductor and a leakage releaser respectively connected to the control circuit board. The mutual inductor is connected to the main line of each contact unit, and the mutual inductor feeds back a current signal to the controller of the control circuit board. The controller outputs a control signal to drive the leakage protector to operate, so that the operating system 22 trips and cuts off the power. Of course, the tripping system can also include a test button and a test circuit, wherein the test circuit draws power from the main line of at least one contact unit, and the test circuit passes through the center hole of the mutual inductor. The test circuit is connected or terminated by the test button, and the tripping system in the circuit breaker body is the prior art.
[0040] The circuit breaker also includes an accessory module 1 with a shunt tripping function. The accessory module 1 is assembled with the circuit breaker body. The accessory module 1 includes an accessory housing 10. A handle mechanism 11 is rotatably mounted on the accessory housing 10. The handle mechanism 11 is linked to a handle assembly 21 of the circuit breaker body. An operating mechanism 12, a contact mechanism and a shunt tripping mechanism 13 are arranged in the accessory housing 10. The contact mechanism includes an auxiliary moving contact 141 and an auxiliary static contact 142 that cooperate with each other. The handle assembly 21, the operating mechanism 12 and the auxiliary moving contact 141 are linked in sequence. The shunt tripping mechanism 13 is used to trigger the operating mechanism 12 to trip. Specifically, the shunt tripping mechanism 13 includes a coil assembly 130 and a moving assembly driven by the coil assembly 130. The moving assembly cooperates with the operating mechanism 12. When the coil assembly 130 is energized, the operating mechanism 12 is triggered to trip by the moving assembly. Usually, the shunt tripping mechanism 13 is also used to drive the operating system 22 of the circuit breaker body to trip, thereby realizing remote operation of the circuit breaker.
[0041] The improvement of the present application is that the moving assembly is connected with a first linkage member 151, the auxiliary moving contact 141 is connected with a second linkage member 152, and the first linkage member 151 and the second linkage member 152 extend out of the accessory housing 10 from the same side wall of the accessory housing 10. In this way, the first linkage member 151 and the second linkage member 152 extend out of the accessory housing 10 from the same side, which is convenient for assembly with the circuit breaker body, and only through the first linkage member 151 and the second linkage member 152 and the operating system 22 of the circuit breaker body, it has the advantages of simple structure, few linkage components and high modularity, and is convenient for assembly.
[0042] Specifically, a first linkage hole a and a second linkage hole b are provided on the same side of the accessory shell 10. The first linkage member 151 passes through the first linkage hole a and moves in a straight line along the first linkage hole a, which is beneficial to reducing the space occupied by the moving stroke of the first linkage member 151. The moving stroke is controllable and the reliability is high. The second linkage member 152 passes through the second linkage hole b and moves in an arc along the second linkage hole b.
[0043] Furthermore, the shunt tripping mechanism 13 includes a coil assembly 130 and a magnetic member 133. The electromagnetic coil 131 cooperates with the magnetic member 133 to generate a magnetic field to drive a moving assembly. The moving assembly includes an armature 134 and a reset member 135 for driving the armature 134 to reset. The armature 134 includes an attraction area 1340 spaced opposite to the driving end of the coil assembly 130. One end of the attraction area 1340 is connected to a rotating end 1341. The armature 134 is rotatably assembled on the outside of the magnetic member 133 through the rotating end 1341. The other end of the attraction area 1340 is connected to a moving end 1342. The moving end 1342 slidably cooperates with the edge of the magnetic member 133 to make the moving end 1342 move in a straight line. The first linkage member 151 is connected to the moving end 1342, which is beneficial to ensuring the stability of the first linkage member 151 moving in a straight line and preventing the first linkage member 151 from being excessively worn by the first linkage hole a due to unbalanced force.

[0045] like Figure 1-6As shown, the accessory module 1 includes an accessory housing 10, and the accessory housing 10 is rotatably equipped with a handle mechanism 11, an operating mechanism 12, a contact mechanism and a shunt tripping mechanism 13, wherein the handle mechanism 11, the operating mechanism 12 (contact mechanism) and the shunt tripping mechanism 13 are arranged in sequence along a first direction, and the handle mechanism 1111 includes an auxiliary handle 111 and an auxiliary connecting rod 112, wherein the auxiliary handle 11 is rotatably assembled on the accessory housing 10, one end of the auxiliary connecting rod 112 is connected to the auxiliary handle 111, and the operating mechanism 12 includes a rotatably assembled auxiliary lever 121, The auxiliary lever 121 is rotatably equipped with an auxiliary jump buckle 122 and an auxiliary lock buckle 123. One end of the auxiliary connecting rod 112 is connected to the auxiliary jump buckle 122 and cooperates with the auxiliary lever 121. The auxiliary jump buckle 122 is snap-fitted with one end of the auxiliary lock buckle 123. The contact mechanism includes an auxiliary static contact 142 and an auxiliary moving contact 141 that cooperate with each other. The auxiliary moving contact 141 is drivingly matched with the auxiliary lever 121. The auxiliary static contact 142 is spaced apart from the operating mechanism 12 in the second direction. The auxiliary moving contact 141 is spaced apart from the auxiliary static contact 142 in the first direction. Figure 3-6 In the embodiment, the auxiliary moving contact 141 is roughly parallel to the second direction, and the operating handle mechanism 11 can drive the auxiliary moving contact 141 to approach or move away from the auxiliary static contact 142, thereby realizing the opening and closing of the accessory module 1. The first direction is perpendicular to the second direction, and the third direction is perpendicular to the first direction and the second direction at the same time. Figure 3 , the up-and-down direction is the first direction, the left-and-right direction is the second direction, and the direction perpendicular to the paper surface is the third direction.
[0046] The shunt tripping mechanism 13 is arranged on one side of the operating mechanism 12 and is used to trigger the operating mechanism 12 to trip. When the shunt tripping mechanism 13 receives the control command, the shunt tripping mechanism 13 triggers the operating mechanism 12 to trip. Specifically, the shunt tripping mechanism 13 includes a coil assembly 130, a magnetic conductive part 133 and a moving assembly. When the coil assembly 130 is energized, the coil assembly 130 and the magnetic conductive part 133 cooperate to form a magnetic field to drive the moving assembly. The moving assembly cooperates with the other end of the auxiliary lock buckle 123, and the auxiliary lock buckle 123 is driven by the moving assembly to rotate, thereby causing the operating mechanism 12 to trip.
[0047] After the accessory module 1 is assembled with the circuit breaker body, in the present embodiment, the circuit breaker body and the accessory module 1 are assembled in the third direction, so that the circuit breaker as a whole has the function of remote operation, that is, after the accessory module 1 receives the tripping signal, the operating mechanism 12 of the accessory module 1 first trips and then drives the operating system 22 of the circuit breaker body to trip; when the circuit breaker body receives the tripping signal, the operating system 22 of the circuit breaker body first trips and then drives the operating mechanism 12 of the accessory module 1 to trip.
[0048] In this embodiment, an assembly structure is provided between the accessory housing 10 and the outer shell, and the assembly structure includes a buckle c and a card slot that cooperate with each other, wherein the buckle c matches the card slot in number and is multiple. Figure 1 In the embodiment, at least one buckle c is provided on the side of the accessory housing 10, and a slot matching the buckle c is provided on the outer shell, thereby having the advantage of convenient assembly and disassembly.
[0049] Specific as Figure 5-9 As shown, the moving assembly is provided with a first linkage member 151, and the auxiliary moving contact 141 is provided with a second linkage member 152. The first linkage member 151 and the second linkage member 152 extend out of the accessory housing 10 from the same side wall of the accessory housing 10. In this embodiment, the central axes of the first linkage member 151 and the second linkage member 152 are parallel to the third direction. When the accessory module 1 is assembled with the circuit breaker body, the first linkage member 151 and the second linkage member 152 respectively cooperate with the operating system 22 of the circuit breaker body. Correspondingly, as shown in FIG. Figure 1 , 4 As shown, a first linkage hole a is provided on one side of the accessory shell 10 adjacent to the outer shell, a second linkage hole b is provided on one side of the accessory shell 10 adjacent to the outer shell, and a first linkage hole a is provided on one side of the accessory shell 10 adjacent to the outer shell. The first linkage member 151 and the second linkage member 152 respectively pass through the first linkage hole a and the second linkage hole b to cooperate with the operating system 22.
[0050] The process of the accessory module 1 driving the circuit breaker body to trip is as follows: after the shunt tripping mechanism 13 triggers the operating mechanism 12 of the accessory module 1 to trip, the auxiliary moving contact 141 rotates with the tripping and opening of the operating mechanism 12, and the second linkage 152 triggers the operating system 22 to trip; the process of the circuit breaker body driving the accessory module 1 to trip is as follows: after the residual current release of the tripping system drives the operating system 22 to trip, the tripping rotation of the operating system 22 drives the first linkage 151, and the moving component triggers the operating mechanism 12 to trip.
[0051] In this embodiment, the circuit breaker body adopts the existing technology, the circuit breaker includes a circuit breaker body, the circuit breaker body includes a shell, the shell is rotatably equipped with a handle assembly 21, one end of the handle assembly 21 passes through a handle hole set on the shell and extends out of the shell, that is, the handle assembly 21 extends out of the shell from the cover body, and an operating system 22, a tripping system and at least two contact units are arranged in the shell, a pair of wiring terminals of each contact unit are arranged at intervals in the second direction, and a contact system of the contact unit is arranged between a pair of wiring terminals, and the contact system includes a movable contact and a stationary contact that cooperate with each other, and the movable contact and the stationary contact are respectively electrically connected to a pair of wiring terminals to control the main line of each contact unit to be on and off; in the first direction, the operating system 22 is located between the handle assembly 21 and the contact unit, the handle assembly 21, the operating system 22 and the movable contact are sequentially linked and connected, and the leakage release of the tripping system and the operating system 22 are arranged in parallel along the third direction. When a leakage fault occurs, the leakage release triggers the operating system 22 to trip.
[0052] like Fig.12 As shown, the operating system 22 includes a fixed plate (not shown), a connecting rod assembly and a trip interlock assembly, and the connecting rod assembly and the trip interlock assembly are respectively rotatably assembled on the fixed plate. Preferably, the handle assembly 21 is also assembled on the fixed plate, and the handle assembly 21, the connecting rod assembly and the trip interlock assembly are linked and connected in sequence, wherein the connecting rod assembly includes a connecting rod 221 and a lever 222, and the trip interlock assembly includes a pushing member 223, a jumping buckle 224, a first locking buckle 225 and a second locking buckle 226, one end of the connecting rod 221 is connected to the handle assembly 21, and in the second direction, the pushing member 223 and the jumping buckle 224 are respectively rotatably assembled in the housing on the same side of the handle assembly 21, and the first locking buckle 22 5 and the second lock buckle 226 are engaged with each other and are respectively rotated and assembled in the housing on the other side of the handle assembly 21. One end of the pusher 223 extends along the third direction and cooperates with the top rod of the leakage releaser. The middle part of the pusher 223 forms a buckle arm in the second direction. The buckle arm is buckled with the first matching part of the second lock buckle 226 to form a second buckle structure. One end of the jump buckle 224 is buckled with one end of the first lock buckle 225 in the second direction to form a first buckle structure. A protrusion 221 is provided on one side of the lever 222. The other end of the connecting rod 221 is connected to the protrusion 221 and abuts against the jump buckle 224. The lever 222 is provided with a mounting portion 2222 for connecting the moving contact.
[0053] When the leakage release receives the control signal, it drives the top rod to hit the push piece 223, and the push piece 223 rotates to disintegrate the second buckle structure. The rotating second lock buckle 226 drives the first lock buckle 225 to rotate, thereby disintegrating the first buckle structure. The trip buckle 224 rotates and drives the lever 222 to separate the moving contact from the static contact, and the handle assembly 21 rotates to the opening position.
[0054] In this embodiment, the first linkage 151 cooperates with the jump buckle 224 in the operating system 22, and the second linkage 152 cooperates with the second lock buckle 226 in the operating system 22. When the operating mechanism 12 is disengaged, the second linkage 152 pushes the second lock buckle 226 to rotate, so that the second buckle structure formed by the second lock buckle 226 and the pusher 223 is unlocked. At the same time, the rotation of the second lock buckle 226 drives the first lock buckle 225 to rotate, and the first buckle structure formed by the jump buckle 224 and the first lock buckle 225 is unlocked, and the operating system 22 is disengaged; when the operating system 22 is disengaged, the rotation of the jump buckle 224 drives the first linkage 151 to move, and the first linkage 151 drives the moving component to push the auxiliary lock buckle 123 to rotate, so that the buckle cooperation formed by the auxiliary jump buckle 122 and the auxiliary lock buckle 123 is disintegrated, and the operating mechanism 12 is disengaged. Of course, the second linkage 152 can also cooperate with the first lock buckle 225.
[0055] Combination Figure 7 A structure of an auxiliary moving contact 141 of this embodiment is provided, wherein the auxiliary moving contact 141 comprises an auxiliary support 1411 and a moving contact piece 1412. The auxiliary support 1411 is an overall straight plate structure, one end of the auxiliary support 1411 is driven and cooperated with the auxiliary lever 121 of the operating mechanism 12, and a second linkage member 152 is provided on the side wall of the other end of the auxiliary support 1411. The second linkage member 152 is a rod body, and the moving contact piece 1412 is fitted on the plate surface of the auxiliary support 1411, that is, the moving contact piece 1412 and the second linkage member 152 are respectively located on two adjacent planes of the auxiliary support 1411, and an auxiliary moving contact point 1413 is provided on the end of the moving contact piece 1412 away from the auxiliary lever 121, so that the shunt tripping mechanism 13 has more space for assembly and a reasonable layout.
[0056] In this embodiment, if Figure 3 , 5As shown in Figures 8-11, the shunt tripping mechanism 13 includes a coil assembly 130, a magnetic member 133 and a moving assembly. Similar to the existing structure, the two opposite ends of the coil assembly 130 are respectively used as a driving end and a connecting end. The connection direction between the driving end and the connecting end is parallel to the second direction. The magnetic member 133 is arranged around the outer side of the coil assembly 130. A notch is provided on the side of the magnetic member 133 opposite to the driving end. The moving assembly includes an armature 134 and a reset member 135 for driving the armature 134 to reset. In this embodiment, the auxiliary lock 123 is pushed to rotate by one end of the armature 134 close to the operating mechanism 12. The first linkage member 151 is a rod structure that moves along the third The armature 134 is rotatably mounted on the outer side of the magnetic conductive member 133 and is spaced opposite to the driving end. That is, the armature 134 includes an attraction area 1340, one end of the attraction area 1340 is connected to a rotating end 1341, the rotating end 1341 is rotatably connected to the outer side of the magnetic conductive member 133, the attraction area 1340 is spaced opposite to the driving end and a gap is left between the notches, the other end of the attraction area 1340 is connected to a moving end 1342, the extension direction of the moving end 1342 is at an angle to the extension direction of the attraction area 1340, preferably, the angle between the moving end 1342 and the extension direction of the attraction area 1340 is close to 90°, Figure 3 , 5 In the figure, the moving trajectory of the mobile end 1342 is parallel to the second direction, and the end of the mobile end 1342 away from the attraction area 1340 is opposite to the operating mechanism 12 to trigger the operating mechanism 12 to trip, and the mobile end 1342 moves in a straight line along the outer side of the magnetic conductive part 133. The moving process occupies a small space and the moving stroke is controllable, which improves the coordination reliability between the shunt tripping mechanism 13 and other components.
[0057] Preferably, the moving trajectory of the first linkage member 151 of the present embodiment is a straight line, and its moving trajectory is parallel to the second direction. The moving trajectory of the first linkage member 151 is limited by the first linkage hole a, wherein the first linkage hole a is a strip hole, and the strip hole is opened along the second direction. The moving trajectory of the second linkage member 152 is arc-shaped, and correspondingly, the second linkage hole b is an arc-shaped hole. The moving trajectory of the second linkage member 152 is limited by the second linkage hole b. The first linkage hole a and the second linkage hole b are spaced apart in the second direction to avoid mutual interference between the first linkage member 151 and the second linkage member 152.
[0058] Furthermore, the moving trajectory of the first linkage member 151 can also be limited by the cooperation of the moving component and the first linkage hole a, so as to avoid the first linkage member 151 being limited only by the first linkage hole a, causing the first linkage member 151 to be excessively worn due to unbalanced force. Specifically, the other end of the attraction area 1340 is connected to the moving end 1342, and the extension direction of the moving end 1342 forms an angle with the extension direction of the attraction area 1340, so that the moving end 1342 and the edge of the magnetic conductive part 133 outside the notch are slidably cooperated to move in a straight line, and the moving end 1342 of the armature 134 moves in a straight line along the outside of the magnetic conductive part 133, so that the moving end 1342 occupies a small space during the movement process, and the moving stroke is controllable, thereby improving the cooperation reliability between the shunt release mechanism 13 and other components.
[0059] Preferably, the movable end 1342 is provided with a slide groove, and the edge of the magnetic conductive member 133 is slidably matched with the slide groove, which can further improve the matching stability and reduce the volume.
[0060] Combination Figure 5 , 6 8-11 provide a specific structure of a shunt tripping mechanism 13.
[0061] The shunt tripping mechanism 13 includes a coil assembly 130, a magnetic conductive part 133 and an armature 134. The two opposite ends of the coil assembly 130 serve as a driving end and a connecting end respectively. The coil assembly 130 includes a coil frame 132 and an electromagnetic coil 131 wound around the outside of the coil frame 132. The coil assembly 130 can adopt existing technology.
[0062] The magnetic conductive member 133 is disposed around the outer side of the coil assembly 130, and a notch is formed on a side of the magnetic conductive member 133 opposite to the driving end. Fig. 9 , 11 In the embodiment, the magnetic conductive member 133 is an integrated structure, including a U-shaped magnetic conductive frame and a limiting arm 1332. The opening of the U-shaped magnetic conductive frame is used as a notch, and a connecting portion 1331 is formed by extending from one side of the U-shaped magnetic conductive frame facing the notch. The connecting portion 1331 extends in a direction parallel to the central axis of the notch. The connecting portion 1331 passes through the middle of the coil skeleton 132 in a direction from the connecting end to the driving end. The limiting arm 1332 is connected to one side of the notch, preferably as Fig. 9 , 11 As shown, the limiting arm 1332 is arranged obliquely and is obliquely opposite to the connecting portion 1331 , and one end of the limiting arm 1332 is connected to the side of the notch and extends outside the U-shaped magnetic conductive frame.

Preferably, a limit groove is opened in the attraction area 1340. When the attraction area 1340 is close to the notch, the limit arm 1332 is slidably inserted into the limit groove, which further reduces the swing range of the armature 134 and helps to reduce the overall volume.
[0064] Furthermore, the portion of the limit arm 1332 extending outside the U-shaped magnetic frame is adjacent to the rotating end 1341 of the armature 134. During the rotation of the armature 134, at least a portion of the attraction area 1340 remains connected to the limit arm 1332, so that the bracket can be omitted. In this way, the armature 134 can be directly rotatably connected to the accessory shell 10, that is, the armature 134 is rotatably matched with at least one side wall of the accessory shell 10. Preferably, a support groove is provided on the inner side of the accessory shell 10, and the armature 134 is directly rotatably assembled in the support groove, thereby omitting the bracket, saving parts and space.
[0065] A reset member 135 is connected to the side of the armature 134 facing away from the notch, and the reset member 135 provides a reset driving force for the armature 134. Figure 8-11 As shown, the reset member 135 includes an elastic plate, the middle part of the elastic plate is bent so that the elastic plate is V-shaped as a whole, one end of the elastic plate is attached to the side of the armature 134 facing away from the notch and is fixedly connected to the armature 134, and the other end of the elastic plate is fixedly connected or abutted. Preferably, an abutting boss 103 can also be provided in the accessory housing 10, and the other end of the reset member 135 abuts against the abutting boss 103. Of course, the reset member 135 can also be a spring.

Preferably, one of the limiting bosses 101 can abut against the end of the armature 134 facing away from the coil assembly 130.
[0067] In addition, if Figure 2 As shown, a wiring member 16 is provided in at least one end of the accessory housing 10, and the accessory housing 10 is provided with wiring holes corresponding to the wiring members 16. The number of the wiring members 16 is at least two.
