The conductive frame 23 is clamped in the inside of the wiring frame 21, the upper surface is fixedly connected with the piezoelectric sheet 231, the bottom end is fixedly connected with the conductive block 24, and the conductive frame 23 and the conductive block 24 adopt an integral molding structure.

The locking member 26 is arranged in the containing groove 211, including a fixed rod 261, a rotating rod 262, a connecting rod one 263, a connecting rod two 264, a limiting block 265, a pressing block 266 and an elastic member 267, the fixed rod 261 is fixed in the containing groove 211, the rotating rod 262 is rotatably connected to the outer surface of the fixed rod 261, the rotating rod 262 is provided with a sliding groove 2621 at both ends, the connecting rod one 263 and the connecting rod two 264 are rotatably connected to both ends of the rotating rod 262 respectively, the outer end of the connecting rod one 263 penetrates into the inside of the conductive frame 23 and is fixedly connected with the pressing block 266, the outer end of the connecting rod two 264 penetrates to the outside of the wiring frame 21 and is fixedly connected with the limiting block 265, the elastic member 267 is arranged on the side of the pressing block 266 close to the rotating rod 262, and is attached to the inner wall of the conductive frame 23. The electromagnetic module 3 includes a sealing plate 31 and an electromagnetic coil 32, the sealing plate 31 is fixed in the placement cavity 12, the electromagnetic coil 32 is fixed on the upper surface of the sealing plate 31, and the top end of the electromagnetic coil 32 is fixed with the Y-shaped rod 253 above, for realizing the protection function of the overload and short circuit of the circuit breaker.

[0029] In the initial state, the circuit breaker is not connected to the external wire, and each component is in the preset locking position. Among them, the circumferential outer surface of the wiring frame 21 is attracted by the magnetic block 111 on the inner wall of the connecting port 11 through its own magnetism, the magnetic block 111 adopts a concave arc structure that fits the outer surface of the wiring frame 21, and under the action of magnetic attraction, the wiring frame 21 is accurately centered and horizontally placed in the connecting port 11, with its upper end surface remaining horizontal. At this time, the piezoelectric sheet 231 outside the conductive frame 23 is in a free expansion state and is not subjected to any external pressure, and the inner surface is separated from the outer surface of the pressing block 266 without close contact. The elastic element 267 in the locking piece 26 is in a natural stretching state, and under the action of the elastic force of the elastic element 267, the pressing block 266 is pushed to the inside of the conductive frame 23, driving the connecting rod one 263 to move to the inside of the conductive frame 23. Taking the upper group of wiring modules 2 as an example, since the connecting rod one 263 and the one end of the rotating rod 262 are connected through the sliding groove 2621, the movement of the connecting rod one 263 will drive the rotating rod 262 to rotate clockwise around the axis of the fixed rod 261, and the other end of the rotating rod 262 drives the connecting rod two 264 to move to the outside of the wiring frame 21 through the sliding groove 2621, and finally makes the limiting block 265 at the outer end of the connecting rod two 264 embedded into the limiting groove inside the shell 1. The outer surface of the limiting block 265 is designed in a circular arc shape and tightly fits the inner wall of the limiting groove, achieving reliable clamping. At this time, the wiring frame 21 is kept in a fixed state with the upper end surface horizontal under the action of magnetic attraction positioning of the magnetic block 111 and mechanical clamping locking of the limiting block 265 and the limiting groove, and cannot rotate, thereby ensuring the uniformity of the wiring frame 21 of each circuit breaker during batch installation, and avoiding structural interference caused by angle deviation of the wiring frame 21 during transportation and handling. In this stage, the rotating groove 251 inside the wiring frame 21 and the rotating shaft 252 on the inner wall of the placement cavity 12 remain in close contact, but since the wiring frame 21 is fixed by the locking piece 26, they do not rotate relative to each other. The embedded groove 241 on the lower surface of the conductive block 24 is in sliding connection with the Y-shaped rod 253, and the elastic conductive sheet 254 is tightly attached to the outer surface of the middle position of the Y-shaped rod 253, preparing for subsequent conduction. The electromagnetic coil 32 in the electromagnetic module 3 is in a power-off state, no electromagnetic force is generated, and does not affect the locking state of the wiring module 2.

[0030] The process of connecting the wire of the circuit breaker: Taking the connection port 11 and the internal wiring module 2 as an example, when the external wire needs to be connected, the operator first inserts the wire vertically into the conductive frame 23 inside the wiring frame 21 through the flared design of the upper end of the connection port 11, and then rotates the wire pressing screw 22 by a tool. Since the wire pressing screw 22 is threadedly connected with the screw hole 13 on the outside of the shell 1, during the rotation process, the wire pressing screw 22 moves along the axis of the screw hole 13 towards the inside of the wiring frame 21, and the end gradually approaches and presses the wire, finally tightly pressing the wire between the wire pressing screw 22 and the piezoelectric sheet 231 in the conductive frame 23, realizing the preliminary fixation of the wire and the wiring module 2. During the process of the wire pressing screw 22 pushing the wire to move towards the piezoelectric sheet 231, the piezoelectric sheet 231 is extruded and shrinks towards the inner wall of the wiring frame 21. During the shrinking process of the piezoelectric sheet 231, its inner surface gradually contacts the outer surface of the abutting block 266 in the locking piece 26 and continuously exerts extrusion force on the abutting block 266. After the abutting block 266 is extruded by the piezoelectric sheet 231, it moves towards the direction close to the rotating rod 262 against the elastic force of the elastic piece 267, driving the connecting rod one 263 to move towards the inside of the accommodating groove 211. The connecting rod one 263 drives the rotating rod 262 to rotate counterclockwise around the fixed rod 261 through the sliding groove 2621, and the other end of the rotating rod 262 pulls the connecting rod two 264 to move towards the wiring frame 21 through the sliding groove 2621, so that the limiting block 265 at the outer end of the connecting rod two 264 gradually moves out of the limiting groove of the shell 1.

[0031] Until the inner surface of the piezoelectric sheet 231 completely matches the inner surface of the conductive frame 23 under the action of the wire pressing screw 22 and the wire, and the outer surface of the abutting block 266 is embedded inside the conductive frame 23 and parallel to the inner surface of the conductive frame 23, at this time, the limiting block 265 at the outer end of the connecting rod two 264 finally completely exits the inside of the limiting groove, realizing the release of the locking state of the wiring frame 21. During the release of the locking, the magnetic attraction relationship between the wiring frame 21 and the magnetic block 111 is not released, and the wiring frame 21 still remains in the central placement state, which can avoid the abrupt angular deviation of the wiring frame 21 after the release of the locking, and facilitate the operator to adjust the wire direction; at the same time, the elastic conductive sheet 254 in the embedded groove 241 of the conductive block 24 always tightly matches the Y-shaped rod 253, ensuring the continuity of the conductive path during the release of the locking, and providing protection for the normal operation of the subsequent circuit breaker.

[0032] Process of rotating adjustment of the wiring frame 21: When the locking piece 26 is unlocked, the wiring frame 21 is no longer mechanically constrained by the limiting block 265 and can freely rotate around the rotation axis 252 of the rotating piece 25 to meet different wire directions or the need for horizontal movement of the circuit breaker along the rail. The operator can manually rotate the wiring frame 21 according to the actual wiring direction (such as the above incoming and outgoing line, left incoming and outgoing line, right incoming and outgoing line) or the position change of the circuit breaker after moving along the rail, and adjust the angle of the wiring frame 21 to the optimal state. It should be noted that the magnetic attraction of the magnetic block 111 is small, and its role is to help the wiring frame 21 complete the horizontal positioning in the initial state, and will not produce obvious resistance to the rotation operation of the wiring frame 21 after being unlocked. During rotation, the wiring frame 21 rotates around the rotation axis 252 inside the rotating slot 251 of the inner wall of the placement cavity 12. The fit design of the rotation axis 252 and the rotating slot 251 provides stable rotation support for the wiring frame 21, avoiding shaking or deviation during rotation. When the wiring frame 21 rotates, the internal conductive frame 23 is driven to rotate synchronously, and the conductive block 24 rotates with the conductive frame 23. The lower surface of the conductive block 24 is embedded in the groove 241, which slides along the outer surface of the Y-shaped rod 253. The elastic conductive sheet 254 inside the embedded groove 241 is always in close contact with the Y-shaped rod 253. The elastic conductive sheet 254 compensates for the slight displacement during rotation through elastic deformation, ensuring the stability of the conductive path between the conductive block 24 and the Y-shaped rod 253, and preventing poor contact caused by rotation.

[0033] In this stage, if the circuit breaker needs to be temporarily moved along the rail to create operating space, the operator can push the circuit breaker to slide along the rail. During the movement, the wire will exert a slight tension on the wiring frame 21. At this time, the angle of the wiring frame 21 can be adjusted by rotating it, so that the wire remains in a natural curved state, eliminating the influence of tension on the wire and the wiring end, and preventing damage to the wire insulation or loosening of the wiring end. After adjustment, the wiring frame 21 can maintain the current angle by relying on the tension of the wire itself and the matching accuracy of the rotation axis 252 and the rotating slot 251, without the need for additional locking operations, making the operation convenient and efficient.

[0034] Stable running state: After the wire is connected and the angle of the wiring frame 21 is adjusted, the circuit breaker enters the normal running state. The wire pressing screw 22 continuously applies pressure to the wire to ensure reliable pressure connection between the wire and the conductive frame 23. The conductive frame 23 forms a stable conductive path through the conductive block 24, the elastic conductive sheet 254, and the Y-shaped rod 253. The current is transmitted to the electromagnetic module 3 and other components inside the circuit breaker in sequence through the wire, the conductive frame 23, the conductive block 24, the elastic conductive sheet 254, and the Y-shaped rod 253, realizing the normal conduction of the circuit. The electromagnetic coil 32 in the electromagnetic module 3 is in an energized state, which monitors the current change in the circuit in real time. When an overload or short circuit fault occurs, the electromagnetic force generated by the electromagnetic coil 32 drives the internal mechanism of the circuit breaker to act, achieving tripping protection. The pressing block 266 in the locking piece 26 is always extruded by the piezoelectric sheet 231, so that the limiting block 265 is kept in a state of being separated from the limiting groove and does not interfere with the rotating state of the wiring frame 21. The elastic piece 267 is in a compressed state, and is ready for subsequent locking reset after the wire is disassembled.

[0035] When it is necessary to disassemble the wire, the operator reversely rotates the wire pressing screw 22, the pressure of the wire pressing screw 22 on the wire disappears, the wire returns to the natural state, the extrusion force of the conductive frame 23 on the piezoelectric sheet 231 is released, the piezoelectric sheet 231 returns to the free expansion state, the external force acting on the pressing block 266 disappears, and the elastic piece 267 moves the pressing block 266 to the inside of the conductive frame 23 under the action of the elastic force of the elastic piece 267. Through the linkage of the connecting rod one 263, the rotating rod 262 and the connecting rod two 264, the limiting block 265 is re-embedded into the limiting groove, the wiring frame 21 is locked again, and returns to the initial horizontal state.

[0036] In summary, the circuit breaker has the following advantages: First, in the unconnected state, the wiring frame 21 is double-locked by magnetic adsorption of the magnetic block 111 and mechanical clamping of the limiting block 265, and the concave arc structure of the magnetic block 111 is precisely fitted with the outer surface of the wiring frame 21, so that the wiring frame 21 is stably fixed in the central and horizontal state. The locking piece 26 can ensure that all wiring frames 21 are uniformly oriented during batch assembly, improve the standardization of the electrical box layout, and prevent structural interference with adjacent components or guide rails during transportation and handling.

[0037] Second, the angle of the existing fixed circuit breaker terminal is fixed, and when the wire direction is left-in and right-out or up-in and down-out, the wire needs to be forcibly bent, which may cause damage to the insulation layer and fatigue of the wire core. The wiring frame 21 of the present application can freely adjust the angle according to the actual wiring direction (up-in and out, left-in and out, right-in and out), so that the wire remains in a natural bending state, eliminating the pulling stress and reducing the risk of short circuit and wire breakage. When the existing circuit breaker moves along the guide rail, the wire is easily pulled, causing the terminal to loosen. In the present application, when the operator moves the circuit breaker along the guide rail, the wiring frame 21 can rotate synchronously, adaptively adjust the angle, and offset the pulling force of the wire, without the need to disassemble or bend the wire, greatly improving the convenience of adjusting and maintaining the power distribution system. At the same time, the embedded groove 241 on the lower surface of the conductive block 24 is in sliding connection with the Y-shaped rod 253, and the elastic conductive sheet 254 in the embedded groove 241 is always in close contact with the Y-shaped rod 253. Through elastic deformation, the small displacement in the rotating process is compensated, ensuring stable conductive path during rotation and eliminating the problem of poor contact.

[0038] Thirdly, the piezoelectric sheet 231 is triggered to contract by the pressure of the crimping screw 22 during the wiring process, which can automatically release the locking of the locking member 26 without additional tools or operation steps. When the operator rotates the crimping screw 22 to press the wire, the wire pushes the piezoelectric sheet 231 to contract, the piezoelectric sheet 231 extrudes the pressing block 266, and then drives the rotating rod 262 to rotate through the connecting rod one 263, pulls the connecting rod two 264 and the limiting block 265 out of the limiting groove, realizes the automatic release of the locking of the wiring frame 21, and completes the synchronous operation of the release of the locking and the wiring operation, which completely matches the existing electrician operation habit. The release of the locking is indirectly driven by the crimping pressure of the crimping screw 22, and the limiting block 265 completely exits the limiting groove only when the pressure reaches the preset value, which can avoid the rotation of the wiring frame 21 caused by the mistaken release of the locking when the wiring is not completed, and ensure the stability of the wire crimping during the wiring process.

[0039] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit it; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalents; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present application.
