[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] Example: like Figure 1-4The diagram shows a quick-release structure for wiring electrical components provided in this embodiment, including a cabinet 1, a fixed connector component 2, a quick-release electrical component 3, a guide structure, and a slide assembly; The quick-release electrical component 3 includes a circuit breaker 31 and a first connector 32 (male connector) electrically connected to the circuit breaker 31; the fixed connector component 2 includes a second connector 21 (female connector, capable of being plugged into the male connector) connected to the circuit inside the cabinet. The fixed connector component 2 is fixed inside the cabinet sheet metal 11 of the cabinet 1. The quick-release electrical component 3 can be installed inside the cabinet sheet metal 11, so that the first connector 32 of the quick-release electrical component 3 is plugged into the second connector 21 of the fixed connector component 2 (electrical connection). The quick-release electrical component 3 can also be removed from the cabinet sheet metal 11, so that the first connector 32 and the second connector 21 are separated. Both the fixed connector component 2 and the quick-release electrical component 3 are equipped with the guide structure, and both the quick-release electrical component 3 and the cabinet sheet metal 11 are equipped with the slide rail assembly. The guide structure and the slide rail assembly are used to guide the quick-release electrical component 3 during the insertion and separation of the first connector 32 and the second connector 21. In this quick-disassembly structure, the guide device achieves primary positioning, and then the first connector and the second connector 21 achieve secondary positioning, completing the quick connection or disconnection of the circuit breaker 31 and the cabinet circuit.

[0016] This utility model discloses a quick-release structure for wiring electrical components. Through the guiding function of the guide structure and the slide rail assembly, the quick-release electrical components can be quickly and stably installed in the sheet metal of the cabinet. This ensures that the first connector of the quick-release electrical component and the second connector of the fixed connector component can be quickly plugged in. At the same time, the first and second connectors are kept aligned during the plugging and unplugging process to avoid connection failures or component damage caused by misalignment. In addition, the slide rail assembly supports and guides the quick-release electrical components, making the installation and removal of the quick-release electrical components smoother and less labor-intensive, without the need for additional complex tools to adjust the position of the components. This structure can realize the quick and reliable connection and disconnection of the circuit breaker in the quick-release electrical component and the internal wiring of the cabinet. It eliminates the need for cumbersome wiring connection or disconnection work between the circuit breaker and the cabinet wiring, effectively reducing manual operation steps and time costs. It can greatly improve the operational efficiency of installation, maintenance and replacement of wiring electrical components, while reducing electrical safety hazards caused by manual wiring errors.

[0017] In a specific embodiment, such as Figure 9-10As shown, the guide structure on the quick-release electrical component 3 is a guide pin 4 provided on both sides of the quick-release electrical component 3. The guide pin 4 includes a plug section 41 and a body section 42 connected to the plug section 41. The plug section 41 and the body section 42 are both arranged along the axial direction of the guide pin 4. The outer diameter of the plug section 41 is smaller than the outer diameter of the body section 42. like Figure 5 , Figure 7-8 As shown, the guide structure on the fixed connector component 2 is a guide sleeve 5 with a guide hole inside. A first guide section 51, a transition section 52 and a second guide section 53 are sequentially arranged in the guide hole along its axial direction. The transition section 52 is obliquely arranged and its two ends are respectively connected to the end of the first guide section 51 and the end of the second guide section 53. The inner wall diameter of the first guide section 51 is larger than the inner wall diameter of the second guide section 53. When the first connector 32 is inserted into the second connector 21, the circumferential outer wall of the insertion segment 41 contacts the circumferential inner wall of the second guide segment 53, and the circumferential outer wall of the body segment 42 contacts the circumferential inner wall of the first guide segment 51.

[0018] When the quick-release electrical component 3 is inserted into the cabinet sheet metal 11, enabling the first connector 32 and the second connector 21 to be connected, the quick-release electrical component 3 drives the guide pin 4 on it to move synchronously. The insertion section 41 of the guide pin 4 first enters the first guide section 51 of the guide sleeve 5 on the fixed connector component 2. Because the inner diameter of the first guide section 51 is larger than that of the second guide section 53, and the outer diameter of the insertion section 41 is smaller than that of the body section 42, the insertion section 41 can smoothly enter the first guide section 51. As the quick-release electrical component 3 continues to advance, the insertion section 41 moves along the first guide section 51 to... The transition section 52, with its oblique structure, guides the insertion section 41, causing the guide pin 4 to gradually calibrate its position, allowing the insertion section 41 to smoothly transition to the second guide section 53. Simultaneously, the body section 42 of the guide pin 4 moves with the insertion section 41, gradually entering the first guide section 51. When the first connector 32 and the second connector 21 are fully inserted, the circumferential outer wall of the insertion section 41 contacts the circumferential inner wall of the second guide section 53, and the circumferential outer wall of the body section 42 contacts the circumferential inner wall of the first guide section 51, achieving precise engagement between the guide pin 4 and the guide sleeve 5.

[0019] When the quick-release electrical component 3 is disassembled from the cabinet sheet metal 11, separating the first connector 32 from the second connector 21, the quick-release electrical component 3 is pulled in the opposite direction, causing the guide pin 4 to move in the opposite direction simultaneously. At this time, the insertion section 41 of the guide pin 4 first exits from the second guide section 53 and enters the transition section 52. The oblique structure of the transition section 52 provides reverse guidance for the insertion section 41, preventing the insertion section 41 from getting stuck with the inner wall of the guide hole. As the quick-release electrical component 3 continues to be pulled, the insertion section 41 smoothly transitions along the transition section 52 to the first guide section 51. At the same time, the body section 42 of the guide pin 4 gradually exits from the first guide section 51 until the first connector 32 and the second connector 21 are completely separated. The guide pin 4 then exits from the guide sleeve 5 as a whole, completing the disassembly.

[0020] The guide pin 4 is designed to precisely engage with the guide hole of the guide sleeve 5, providing stable support for the quick-release electrical component 3 during insertion and disassembly. Through the insertion sections 41 and the body section 42 with different outer diameters, the second guide section 53 and the first guide section 51 of the guide hole are respectively adapted to ensure that the guide pin 4 and the guide sleeve 5 remain in a close guiding state throughout the entire movement, preventing the quick-release electrical component 3 from shifting and ensuring that the first connector 32 and the second connector 21 can accurately connect or separate. The guide sleeve 5 and its internal first guide section 51, transition section 52, and guide hole of the second guide section 53 are also designed. The purpose is to provide layered guidance for the guide pin 4 by using the first guide section 51 and the second guide section 53 with different inner diameters to respectively adapt to the body section 42 and the insertion section 41 of the guide pin 4; by using the obliquely set transition section 52, the guide pin 4 can smoothly transition between the first guide section 51 and the second guide section 53, avoiding movement jamming; the whole provides a precise path for the movement of the guide pin 4, further ensuring the stability and accuracy of the quick-release electrical components 3 during insertion and disassembly, and assisting the first connector 32 and the second connector 21 to efficiently complete docking or separation; the structural diagram after the guide pin and guide sleeve are inserted is shown in the figure. Figure 11-12 As shown.

[0021] In a specific embodiment, the slide rail assembly on the cabinet sheet metal 11 is an L-shaped guide plate 6 provided on both sides of the inner wall of the cabinet sheet metal 11. The L-shaped guide plate 6 includes a vertically arranged connecting part 61 and a horizontally arranged supporting part 62 connected to the end of the connecting part 61. The connecting part 61 is fixed on the inner wall of the cabinet sheet metal 11. The slide rail assembly on the quick-release electrical component 3 is an abutment plate 7 fixed on both sides of the quick-release electrical component 3 and arranged in the lateral direction; During the insertion and separation of the first connector 32 and the second connector 21, the bottom of the abutment plate 7 abuts against the top of the support portion 62 and is able to slide on the support portion 62.

[0022] When an external force is applied to the quick-release electrical component 3 into the cabinet sheet metal 11, the quick-release electrical component 3 is driven to move into the cabinet sheet metal 11. The quick-release electrical component 3 drives the abutment plates 7 on both sides of it to move synchronously. At this time, the bottom of the abutment plate 7 always abuts against the top of the support portion 62 of the L-shaped guide plate on both sides of the inner wall of the cabinet sheet metal 11, and the connecting portion 61 of the L-shaped guide plate, which slides smoothly on the support portion 62 as the quick-release electrical component 3 moves, remains stationary because it is fixed to the inner wall of the cabinet sheet metal 11, providing stable support for the support portion 62. Until the first connector 32 of the quick-release electrical component 3 and the second connector 21 of the fixed connector component 2 are inserted, the abutment plate 7 stops at the corresponding position of the support portion 62, and the insertion process ends. When an external force is applied to the quick-release electrical component 3 toward the outside of the cabinet sheet metal 11, the quick-release electrical component 3 is driven to move outward of the cabinet sheet metal 11. The quick-release electrical component 3 drives the abutment plates 7 on both sides of it to move in the opposite direction simultaneously. At this time, the bottom of the abutment plate 7 still abuts against the top of the support part 62 of the L-shaped guide plate 6, and slides in the opposite direction on the support part 62 as the quick-release electrical component 3 moves, until the first connector 32 of the quick-release electrical component 3 is completely separated from the second connector 21 of the fixed connector component 2. The abutment plate 7 moves out of the cabinet sheet metal 11 together with the quick-release electrical component 3, and the disassembly process ends.

[0023] The abutment plate 7 cooperates with the support portion 62 of the L-shaped guide plate. On the one hand, it obtains support by abutting the support portion 62 at the bottom, preventing the quick-release electrical component 3 from sagging when moving. On the other hand, it guides the quick-release electrical component 3 to move along a fixed path by sliding on the support portion 62, assisting the first connector 32 and the second connector 21 to accurately mate or separate, and improving the efficiency of insertion or separation.

[0024] In a specific embodiment, such as Figure 6 As shown, the quick-release electrical component 3 also includes a first sheet metal frame 33, the first connector 32 and the circuit breaker 31 are respectively disposed at the front end A and the rear end B of the first sheet metal frame 33, the guide pin 4 is disposed at the front end A of the first sheet metal frame 33, and the abutment plate 7 is fixed on both sides of the first sheet metal frame 33. The core function of the first sheet metal frame 33 is to provide an integrated installation carrier and structural support for the key components of the quick-release electrical component 3. On the one hand, the first connector 32 and guide pin 4 are installed at the front end, the circuit breaker 31 is installed at the rear end, and the abutment plates 7 are fixed on both sides. This integrates the circuit breaker 31, the first connector 32, the guide pin 4, and the abutment plates 7 into a whole, forming a structurally stable quick-release unit and ensuring that the positions of each component are relatively fixed. On the other hand, during the insertion and disassembly process, the first sheet metal frame 33 can transmit external force to drive the entire quick-release unit to move. At the same time, it supports each component through its own structural strength, preventing the component from shifting or deforming due to movement or force, ensuring the smoothness and accuracy of the overall disassembly and assembly of the quick-release electrical component 3, and assisting in the rapid connection and disconnection of the circuit breaker 31 and the cabinet wiring.

[0025] In a specific embodiment, such as Figure 5 As shown, the fixed connector component 2 includes a second sheet metal frame 22, the second connector 21 is disposed on the second sheet metal frame 22, and the guide sleeve 5 is disposed on both sides of the second sheet metal frame 22. The second sheet metal frame 22 provides a stable mounting base for the second connector 21 and the guide sleeve 5, ensuring that the second connector 21 and the guide sleeve 5 are accurately positioned and relatively fixed, thereby meeting the requirements for insertion with the first connector 32 of the quick-release electrical component 3 and cooperation with the guide pin 4. At the same time, its own structural strength ensures that the fixed connector component 2 does not shift during disassembly and assembly, assisting in the smooth disassembly and assembly of the quick-release electrical component 3.

[0026] In a specific embodiment, a fixing sheet metal 8 is also included, which is used to fix the first sheet metal frame 33 to the cabinet sheet metal 11, and to fix the second sheet metal frame 22 to the cabinet sheet metal 11.

[0027] The fixed sheet metal is L-shaped, including a cabinet connecting part 81 and a sheet metal frame connecting part 82 set at a 90° angle to the cabinet connecting part 81. Both the cabinet connecting part 81 and the sheet metal frame connecting part 82 are provided with mounting holes. Simultaneously, the cabinet sheet metal 11, the first sheet metal frame 33, and the second sheet metal frame 22 are also provided with mounting holes. Bolts pass through the fixing holes to fix the second sheet metal frame 22 inside the cabinet sheet metal 11. At this time, the side wall of the cabinet connecting part 61 abuts against the inner wall of the cabinet sheet metal 11, and the side wall of the sheet metal frame connecting part 82 abuts against the side wall of the second sheet metal frame 22. After the quick-release electrical component 3 is installed into the cabinet sheet metal 11 and the first sheet metal frame 33 is installed into the cabinet sheet metal 11 (the first... After connector 32 is plugged into the second connector 21, bolts are passed through the mounting holes on the cabinet connecting part 81 and the cabinet sheet metal 11, and through the mounting holes on the sheet metal frame connecting part 82 and the first sheet metal frame 33. The bolts are tightened, and the rear end of the first sheet metal frame 33 (i.e. the end near the entrance of the cabinet sheet metal 11) is fixed to the cabinet sheet metal 11 by fixing the sheet metal and bolts, thereby ensuring the positional stability of the first sheet metal frame 33. In turn, when the first sheet metal frame 33 is fixed to the cabinet sheet metal 11, the side wall of the cabinet connecting part 81 abuts against the inner wall of the cabinet sheet metal 11, and the side wall of the sheet metal frame connecting part 82 abuts against the side wall of the first sheet metal frame 33. The fixed sheet metal can be connected to the first sheet metal frame 33 (after insertion) and the second sheet metal frame 22 with the cabinet sheet metal 11 through the L-shaped cabinet connecting part 81 and the sheet metal frame connecting part 82, respectively, with bolts, to ensure that the two are in a stable position inside the cabinet, thereby ensuring that the first connector 32 and the second connector 21 are reliably connected and preventing the quick-release electrical components 3 from loosening.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
