Abstract
Description
Technical Field
[0001] This utility model relates to the field of fuse technology, specifically a support component for a cylindrical cap-shaped fuse. Background Technology
[0002] A fuse is an electrical device that breaks the circuit by melting its fusible element when the current exceeds a specified value. Fuses are current protection devices that utilize the principle that when the current exceeds a specified value for a certain period, the heat generated by the fuse itself melts the fusible element, thus breaking the circuit. Fuses are widely used in high and low voltage power distribution systems, control systems, and electrical equipment as short-circuit and overcurrent protectors, and are one of the most commonly used protective devices.
[0003] With the development of electrical equipment and the diversification of application needs, the requirements for support components for cylindrical cap-shaped fuses are becoming increasingly stringent. Especially in applications requiring multiple fuses to work together, traditional single-structure fuses are no longer sufficient. Therefore, developing a support component for fuses with a modular structure, allowing for easy assembly to adapt to different usage requirements, is particularly important. Summary of the Invention
[0004] The purpose of this invention is to provide a support component for a cylindrical cap-shaped fuse, addressing the issue mentioned in the background art, particularly in situations requiring multiple fuses to work together, where traditional single-structure fuses are no longer sufficient. Therefore, developing a support component for fuses with a modular structure, enabling easy assembly to adapt to different usage requirements, is of paramount importance.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a support component for a cylindrical cap-shaped fuse, comprising a fuse housing, wherein cavities are formed at both ends of one side surface of the fuse housing, and a limiting module is provided in the cavity; a limiting groove adapted to the limiting module is formed at the opposite position of the limiting module on the other side surface of the fuse housing, and the limiting module is engaged in the limiting groove; a guide cylinder is fixedly installed around one side surface of the fuse housing; and a guide hole adapted to the guide cylinder is formed around the opposite position of the guide cylinder on the other side surface of the fuse housing, and the guide cylinder is inserted into the guide hole.
[0006] Preferably, a locking slot is provided in the limiting groove.
[0007] Preferably, the limiting module includes a connecting block, a snap-fit block, and a backstop arm. The snap-fit block is fixedly connected to one end surface of the connecting block and snaps into the bayonet. The backstop arm is fixedly connected to the other end surface of the connecting block.
[0008] Preferably, the fuse housing surface has a through hole at a position opposite to the cavity, and a locking arm is engaged in the through hole.
[0009] Beneficial effects
[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows:
[0011] This invention utilizes a design that combines a limiting module and a limiting groove to facilitate the easy assembly of multiple fuses into a combined structure. This allows users to flexibly select the number and arrangement of the trip units according to their specific needs, thereby meeting diverse usage requirements. Attached Figure Description

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.
[0019] In the description of this utility model, it should be noted that the terms "upper," "lower," "left," "right," "front," "rear," "inner," "outer," "vertical," and "horizontal," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0020] like Figure 1-3 This is a schematic diagram of the structure of a support member for a cylindrical cap-shaped fuse according to a preferred embodiment of the present invention. In this embodiment, the support member for a cylindrical cap-shaped fuse includes a fuse housing 1. A cavity 2 is formed at both the front and rear ends of one side surface of the fuse housing 1, and a limiting module 3 is disposed within the cavity 2. A limiting groove 5, adapted to the limiting module 3, is formed on the other side surface of the fuse housing 1 at a position opposite to the limiting module 3. The limiting module 3 is engaged within the limiting groove 5, thereby enabling the splicing of multiple fuse housings 1. A guide cylinder 4 is fixedly installed around one side of the fuse housing 1, and guide holes 8, adapted to the guide cylinder 4, are opened around the other side of the fuse housing 1 at positions opposite to the guide cylinder 4. The guide cylinder 4 is inserted into the guide hole 8. This structural design provides guidance during the splicing of multiple fuse housings 1, preventing positional misalignment during splicing. Combined with the design of the limiting module 3 and the limiting groove 5, multiple fuses can be easily assembled together to form a combined structure. In this way, users can flexibly choose the number and arrangement of the trip units according to actual needs, thereby meeting different usage requirements.
[0021] In this embodiment, a bayonet 7 is provided in the limiting groove 5.
[0022] In this embodiment, the limiting module 3 includes a connecting block 31, a snap-fit block 32, and a backstop arm 33. The snap-fit block 32 is fixedly connected to one end surface of the connecting block 31, and the snap-fit block 32 snaps into the bayonet 7. By snapping the snap-fit block 32 into the bayonet 7, the splicing and fixing of multiple fuse housings 1 can be realized. The backstop arm 33 is fixedly connected to the other end surface of the connecting block 31.
[0023] In this embodiment, a through hole 6 is provided on the surface of the fuse housing 1 at a position opposite to the cavity 2, and a retaining arm 33 is engaged in the through hole 6. With this structural design, if only a single fuse is needed in the application environment, there is no need to splice. A tool can be inserted into the through hole 6 and placed on the outer wall of the retaining arm 33 to make it disengage from the through hole 6, thereby realizing the removal of the limiting module 3 from the cavity 2.
[0024] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
