[0002] As the functions of air-conditioning systems become increasingly complex, the density of pipelines has also increased significantly. Electromagnetic compatibility (EMC) requirements have made the application of magnetic rings an important consideration in design. The commonly used method of fixing magnetic rings is to fix them with cable ties. Common operating steps include cable ties and wire cutting, which increase the complexity of operations and production inefficiency. Due to the small operating space and the sharp cable tie head, it is easy to scratch the operator's hands, seriously affecting the assembly efficiency of the magnetic ring and the health of the operator.

[0003] In order to solve the above technical problems in the prior art, the fixing structure for fixing the magnetic ring is integrally injection molded with the shell of the electrical box. Different electrical boxes need to be designed for different products, and the number and setting positions of the fixing structures need to be determined during the design of the electrical box, which makes the electrical box not universal. In particular, when the product is adjusted and the magnetic ring is not needed, the magnetic ring fixing structure will still occupy the internal space of the electrical box, resulting in poor scalability of the electrical box and inability to adapt to diverse application requirements. Summary of the invention

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0031] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "setting", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, an indirect connection through an intermediate medium, or the internal connection of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In order to solve the above technical problems in the prior art, the fixing structure for fixing the magnetic ring is integrally injection molded with the shell of the electrical box. Different electrical boxes need to be designed for different products, and the number and setting positions of the fixing structures need to be determined during the design of the electrical box, which makes the electrical box not universal. In particular, when the product is adjusted and the magnetic ring is not needed, the magnetic ring fixing structure will still occupy the internal space of the electrical box, resulting in poor scalability of the electrical box and inability to adapt to diverse application requirements.

[0033] To this end, the present application provides a Figures 1 to 6The magnetic ring fixing device shown includes: a base 1; a clamping structure, the clamping structure is arranged on the base 1, and the clamping structure and the base 1 together enclose a clamping space for fixing the magnetic ring 10; the base 1 is provided with a first clamping structure 11 and a second clamping structure 12, and the clamping structure is provided with a third clamping structure 21, the base 1 can be clamped and matched with the preset structure 20 through the first clamping structure 11, and the base 1 can also be clamped and matched with the third clamping structure 21 of another magnetic ring fixing device through the second clamping structure 12 to achieve a stacked arrangement of two magnetic ring fixing devices. By providing the first clamping structure 11 on the base 1, the base 1 can be disassembled and assembled on the preset structure 20, so that it can be installed when needed and disassembled when not needed, which solves the problem of space occupied by the fixed structure in the prior art and improves the space utilization rate of the electrical box. At the same time, the second clamping structure 12 is clamped and matched with the third clamping structure 21 of another magnetic ring fixing device to achieve stacking of two magnetic ring fixing devices, which can not only increase the number of fixed magnetic rings 10, but also separate the routing of strong and weak electricity according to the layout of strong and weak electricity to prevent strong and weak electricity from interfering with each other. In addition, the clamping structure can realize the rapid disassembly and assembly of the magnetic ring 10, thereby achieving the purpose of improving the disassembly and assembly efficiency of the magnetic ring 10.

[0034] When in use, the number of magnetic ring fixing devices is selected according to the determined number of magnetic rings 10, so that each clamping structure can fix one magnetic ring 10. When one magnetic ring fixing device is needed, the first clamping structure 11 is used to clamp and cooperate with the preset structure 20, and then the corresponding magnetic ring 10 is set on the magnetic ring fixing device. When two or more magnetic ring fixing devices are needed, one magnetic ring fixing device is first clamped with the preset structure 20 through the first clamping structure 11, and the corresponding magnetic ring 10 is set on the magnetic ring fixing device, and then another magnetic ring fixing device is fixed on the already fixed magnetic ring fixing device using the second clamping structure 12 and the third clamping structure 21 until all magnetic rings 10 are installed. In particular, when the air-conditioning unit has low requirements for electromagnetic compatibility, the magnetic ring fixing device can be easily disassembled to release space for the installation of other components. The problem of space occupied by the fixed structure in the prior art is solved, the space utilization rate of the electrical box is improved, and the efficiency of disassembly and assembly of the magnetic ring 10 is improved.

[0035] Since the magnetic ring 10 has different sizes, a slide rail 13 is provided on the base 1, and the clamping structure includes two claws 22 arranged opposite to each other, at least one of the claws 22 is movably provided on the slide rail 13, and the two claws 22 can move relative to each other to adjust the size of the clamping space. By adjusting the claws 22, the clamping structure can fix magnetic rings 10 of different sizes, further improving the adaptability and versatility of the magnetic ring fixing device.

[0036] The base 1 is provided with a locking structure, which has a locking state in which the claw 22 is locked on the base 1 and a disengaged state in which the claw 22 can move freely on the slide rail 13. The claw 22 is locked by the locking structure to ensure that the clamping structure can reliably fix the magnetic ring 10 in the clamping space.

[0037] As an embodiment, a plurality of slots are provided below the slide rail 13, and all the slots are arranged along the length direction of the slide rail 13. A protrusion structure is provided on the claw 22, and the claw 22 can be fixed with a slot by squeezing the protrusion structure in the direction of the slide rail 13, thereby locking the claw 22. When the claw 22 needs to be moved, the claw 22 is lifted upward to make the protrusion structure disengage from the slot, and then the claw 22 is moved along the slide rail 13. When the claw 22 moves to the set position, the claw 22 is squeezed downward to complete the position adjustment of the claw 22, so that the two claws 22 can clamp and fix magnetic rings 10 of different sizes, thereby greatly improving the assembly efficiency and flexibility.

[0038] like Figure 1 As shown, each magnetic ring fixing device is provided with two clamping structures, and each clamping structure can clamp a magnetic ring 10. At this time, four claws 22 are provided on the base 1. When the magnetic ring fixing devices need to be stacked, the four claws 22 can provide four-point support for the upper magnetic ring fixing device to ensure the fixing reliability of the upper magnetic ring fixing device.

[0039] The magnetic ring 10 needs to be arranged in the electrical box, and there will be cables in the electrical box, and a cable fixing structure is arranged on the clamping structure. When the cables pass through the magnetic ring fixing device, the cable fixing structure can be used to fix the cables, which assists in the orderly arrangement of the cables in the electrical box. In particular, when there are strong-current cables and weak-current cables in the electrical box, the strong-current cables and weak-current cables can be fixed separately by means of magnetic ring fixing devices of different layers, thereby achieving physical isolation of strong-current and weak-current lines, ensuring the separation of strong-current and weak-current wiring in the electrical system, and optimizing electromagnetic compatibility and neatness of wiring.

[0040] As an embodiment, the cable fixing structure includes two wire tie fixing holes 23 located on the clamping structure, and the cable can be bundled by sequentially passing through the two wire tie fixing holes 23. When in use, the cable is attached to the outer wall surface of the clamping structure and located between the two wire tie fixing holes 23, and then the wire tie is sequentially passed through the two wire tie fixing holes 23 and surrounds the cable, completing the process of fixing the cable on the clamping structure.

[0041] The base 1 has a first side surface and a second side surface adjacent to each other, the first clamping structure 11 is disposed on the first side surface, and the second clamping structure 12 is disposed on the second side surface. By arranging the first clamping structure 11 and the second clamping structure 12 on different sides of the base 1, respectively, it is possible to avoid interference between the first clamping structure 11 and the third clamping structure 21 when the magnetic ring fixing device is stacked, thereby ensuring reliable use of the magnetic ring fixing device.

[0042] As an embodiment, a clamping protrusion 24 is provided on the outer wall of the clamping structure, and the clamping protrusion constitutes the third clamping structure 21. A clamping hole is formed on the base 1, and the clamping hole constitutes the second clamping structure 12. The clamping protrusion can extend into the corresponding clamping hole to complete the clamping fit, wherein the clamping protrusion is located on the outer wall surface of the claw 22. At this time, the clamping protrusions of the four claws 22 all pass through the corresponding clamping holes from the inside of the base 1 to the outside. Since the two claws 22 in each clamping structure are relatively arranged, the clamping protrusion can be prevented from escaping from the clamping hole, thereby ensuring the connection reliability between the magnetic ring fixing devices.

[0043] A strip-shaped snap-in groove is formed on the side wall of the base 1, and the strip-shaped snap-in groove constitutes the first snap-in structure 11. The snap-in piece on the preset structure 20 can snap-in with any position of the strip-shaped snap-in groove. By setting the strip-shaped snap-in groove, the base 1 can be matched with different preset structures 20, that is, the positioning hook on the preset structure 20 for connecting the magnetic ring fixing device can be selectively designed according to the structural requirements of the preset structure 20, and it is only necessary to make the positioning hook snap-in with the strip-shaped snap-in groove, thereby further improving the application range of the magnetic ring fixing device.

[0044] An electrical box includes a housing and the above-mentioned magnetic ring fixing device, wherein the housing constitutes the preset structure 20. A positioning hook can be provided on the housing, and the positioning hook is used to engage with the first engaging structure 11 on the base 1. The positioning hook can be integrally injection molded with the housing.

[0045] An air conditioner comprises the magnetic ring fixing device or the electrical appliance box.

[0046] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
