Description

Technical Field

[0001] This utility model relates to the field of fuse holder structure, specifically a detachable fuse terminal housing structure. Background Technology

[0002] A fuse terminal block, also known as a fuse holder, is a socket used to install fuses. Due to prolonged use, the elastic conductive element inside the fuse terminal block (which uses spring clips to hold the fuse in place) may fail to return to its original shape, resulting in "elastic failure." In this case, even if the fuse is replaced, the terminal block will not function properly. It is necessary to remove the terminal block, open the end cover, remove the elastic conductive element, and replace it. Current terminal block housings are often one-piece designs, which makes it difficult to quickly remove and replace the elastic conductive element. Utility Model Content

[0003] The purpose of this utility model is to provide a detachable fuse terminal housing structure to solve the problem of inconvenience in using existing fuse terminals.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a detachable fuse terminal housing structure, comprising:

[0005] The main housing provides installation space;

[0006] The top cover is hinged to the main housing at one end, and the top cover is provided with a mounting slot for installing a fuse;

[0007] The bottom cover is snapped into the main housing. An elastic conductive element is provided on the bottom cover, and the elastic conductive element is connected to both sides of the fuse.

[0008] As a further improvement to the above technical solution:

[0009] It also includes side covers that connect to the main housing.

[0010] The main housing is provided with a connecting post, and the top cover is provided with a hook, which is rotatably engaged with the connecting post.

[0011] The main housing is provided with a mounting plate, and the mounting plate is threaded with a wire screw. A perforated connector is provided above the mounting plate, and the top cover is provided with an adjustment hole corresponding to the position of the perforated connector.

[0012] The bottom cover is provided with an abutment plate, which is located below the mounting plate. A guide plate is provided on one side of the abutment plate, and the elastic conductive element is arranged along the guide plate and extends into the abutment plate.

[0013] The main shell, top cover, and bottom cover are all located on the same plane on one side.

[0014] The elastic conductive element has a spring-type structure with a thickness of 0.1-0.3 mm.

[0015] The top cover is equipped with a handle.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] Quick-change fuses and flexible conductive components: A modular design, separating the traditional one-piece housing into a main housing, top cover, bottom cover (and optional side covers), allows for rapid disassembly and assembly. The quick-release design of the bottom cover, in particular, makes replacing flexible conductive components extremely convenient. Users can easily open the bottom cover to remove and replace damaged flexible conductive components without disassembling the entire terminal block, significantly saving maintenance time and costs.

[0018] Easy to observe and operate: The observation hole design on the top cover allows users to easily observe the working status of the fuses at any time, enabling timely detection and handling of problems. The side covers are made of transparent material, further enhancing the visibility of the internal components and facilitating maintenance and operation. The handle design on the top cover makes opening it easier and more convenient.

[0019] Standardized and modular design: The flexible conductive element can be shipped as a complete set with the base cover, enabling standardized production and supply. This modular design not only facilitates production and inventory management for manufacturers but also makes maintenance and replacement easier for users. Users can select the appropriate combination of flexible conductive element and base cover according to their needs, improving the product's versatility and flexibility.

[0020] In summary, this utility model, through its modular and detachable design, achieves advantages such as quick replacement of the fuse terminal housing structure, convenient observation, and easy maintenance, thereby improving the product's practicality, safety, and economy.
