Description

Technical Field

[0001] This utility model relates to the field of switch technology, specifically to a manual maintenance switch that allows for easy installation and disassembly while maintaining insulation protection. Background Technology

[0002] In the field of electrical equipment maintenance technology, manual repair of switches, fuses, and screws are common electrical components, and their installation and removal are crucial aspects of electrical equipment maintenance. During these processes, it is essential to ensure the insulation safety of operators and installation tools to prevent electric shock accidents. Simultaneously, the assembly efficiency of these components directly affects the maintenance efficiency and quality of electrical equipment. Existing fuse and screw assembly methods have several problems. First, because screws and fuses are independent components, they need to be aligned and tightened during assembly, a process that requires time and effort, thus increasing assembly time. Second, because screws and fuses are independent components, screws may fall out during assembly, which not only affects assembly efficiency but may also lead to assembly quality problems. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a manual maintenance switch that can be installed and disassembled to meet insulation protection requirements, thereby solving the shortcomings of the prior art.

[0004] The purpose of this utility model is achieved through the following technical solution: a manual maintenance switch that is installed and disassembled with insulation protection, including a plug housing and a base, wherein the plug housing is connected to the base by an external screw, and also includes a fuse assembly, wherein the fuse assembly is disposed between the plug housing and the base, the fuse assembly including a fuse sleeve, a screw and a fuse, wherein the fuse is connected to the fuse sleeve by the screw to form an integral assembly, and the tail of the screw passes through the fuse sleeve and the fuse and is threaded to the base.

[0005] Furthermore, the fuse sleeve has a countersunk hole and a through hole sequentially from top to bottom, the tail of the screw passes through the through hole, and the head of the screw is movably disposed in the countersunk hole.

[0006] Furthermore, there are two screws arranged symmetrically on the left and right sides.

[0007] Furthermore, an elastic fastener is fixed to the inner top wall of the plug housing. The end of the elastic fastener near the base forms a hook-shaped part, and the end of the hook-shaped part near the base is provided with a wedge-shaped surface. The end of the hook-shaped part away from the base forms an abutting plane. An abutting part is formed on the side wall of the fuse. When the fuse assembly is assembled, the abutting part abuts against the abutting plane.

[0008] The beneficial effects of this utility model are:

[0009] 1. Improve assembly efficiency: By forming the fuse, screw and fuse sleeve into a component, the assembly time is reduced and the assembly efficiency is improved. The screw and fuse are no longer independent parts, but a whole component. This avoids the alignment and tightening process during assembly, saving time and effort.

[0010] 2. Preventing screws from falling out: The fuse sleeve structure restricts the fuse and screw to be integrated into one component, reducing the screw assembly and alignment process. Furthermore, the plug housing prevents the screw from falling out of the fuse sleeve. This not only avoids the problem of screws falling out, but also improves assembly quality and ensures the normal operation of electrical equipment.

[0011] 3. Provides insulation protection: The fuse sleeve not only protects the fuse and screws, but also provides insulation protection for installation tools and installers, preventing electric shock accidents and improving operational safety. Attached Figure Description

[0015] Example 1

[0016] like Figure 1 and Figure 2As shown, a manual maintenance switch with insulation protection for easy installation and removal includes a plug housing 1 and a base 2. The plug housing 1 is connected to the base 2 by an external screw. It also includes a fuse assembly disposed between the plug housing 1 and the base 2. The fuse assembly includes a fuse sleeve 3, a screw 4, and a fuse 5. The fuse 5 is connected to the fuse sleeve 3 as an integral assembly by the screw 4. The tail of the screw 4 passes through the fuse sleeve 3 and the fuse 5 and is threaded onto the base 2. The fuse sleeve 3 is made of insulating material. The fuse assembly is first installed on the base 2, then the screw 4 is screwed in to install the fuse assembly onto the base 2. Finally, the plug housing 1 and the base 2 are connected together, so that the screw 4 and... The fuse 5 is no longer an independent component, but an integral assembly. This eliminates the need for alignment and tightening during assembly, saving time and effort, reducing assembly time, and improving assembly efficiency. Simultaneously, the fuse assembly is positioned between the plug housing 1 and the base 2, with the screw 4 embedded within the plug housing 1. The plug housing 1 prevents the screw 4 from falling out of the fuse sleeve 3, thus not only preventing the screw 4 from falling out but also improving assembly quality and ensuring the normal operation of the electrical equipment. The fuse sleeve 3 not only protects the fuse 5 and the screw 4 but also provides insulation protection for installation tools and personnel, preventing electric shock accidents and improving operational safety.

[0017] Example 2

[0018] Based on Example 1, such as Figure 2 As shown, an elastic fastener 8 is fixed to the inner top wall of the plug housing 1. A hook-shaped portion 9 is formed at the end of the elastic fastener 8 near the base 2. A wedge-shaped surface 10 is provided at the end of the hook-shaped portion 9 near the base 2. An abutment plane 11 is formed at the end of the hook-shaped portion 9 away from the base 2. An abutment portion 12 is formed on the side wall of the fuse 5. After the fuse assembly is assembled, the abutment portion 12 abuts against the abutment plane 11. The fuse assembly is connected to the plug housing 1 by a snap-fit ​​method. The assembly is simple and efficient. Specifically, the fuse assembly is connected to the base 2... After the base 2 is attached, the plug housing 1 is connected to the base 2. As the plug housing 1 moves closer to the base 2, the wedge-shaped surface 10 of the elastic fastener 8 presses against the abutment part 12. Under the guidance of the wedge-shaped surface 10, the elastic fastener 8 deforms, allowing the hook-shaped part 9 of the elastic fastener 8 to pass smoothly through the abutment part 12. After the hook-shaped part 9 passes through the abutment part 12, it resets. At this time, the fuse assembly is assembled in place, and the hook-shaped part 9 abuts against the abutment plane 11, thereby limiting the fuse assembly and installing it in the plug housing 1, making the assembly of the fuse assembly simple and quick.

[0019] Example 3

[0020] Based on Example 2, such as Figure 1As shown, the fuse sleeve 3 has a countersunk hole 6 and a through hole 7 from top to bottom. The tail of the screw 4 passes through the through hole 7, and the head of the screw 4 is movably disposed in the countersunk hole 6. The countersunk hole 6 allows the screw 4 to be easily rotated to connect to the base 2. At the same time, the screw 4 is hidden in the countersunk hole 6 to avoid interference with the plug housing 1. Preferably, there are two screws 4 arranged symmetrically on the left and right sides, which makes the connection more stable and more reliable.
