Description

Technical Field

[0001] The present application relates to the technical field of fuses, and in particular to a fuse cover that is easy to install. Background Art

[0002] Fuses, as essential safety components in electrical circuits and equipment, are designed to prevent damage caused by overcurrent and short-circuit currents. In their construction, the fuse and an indicator light indicating the fuse's status must be carefully installed inside the fuse cover.

[0003] Within the existing technology, a fuse cover design, such as that disclosed in utility model publication number CN220382038U, comprises a main body and a mounting cavity within the main body, with a sealing cover mounted on the side of the main body. The top edge of the mounting cavity is provided with an insertion opening for the sealing cover, which communicates with the outside. Guide bars are mounted on either side of the sealing cover, and corresponding guide grooves are designed within the inner wall of the mounting cavity to allow the guide bars to be inserted and slide smoothly. The side of the main body also features a stopper to secure the sealing cover.

[0004] However, during actual fuse assembly, the indicator light must first be properly positioned within the mounting cavity within the fuse body. This step requires the operator to slide the sealing cover outward from the insertion port to expose the mounting cavity. While this seemingly simple action presents a hidden danger: the sealing cover is at risk of accidentally falling off during the sliding process. If the sealing cover accidentally separates from the fuse body, the operator must readjust the alignment of the guide bar and guide groove. This repetitive alignment process is not only time-consuming and labor-intensive, but also significantly slows down the assembly of the fuse. Clearly, there is room for improvement and it is necessary. Utility Model Content

[0005] The purpose of the present application is to provide a fuse cover that is easy to install, so as to solve the problem that the sealing cover and the main body may be directly separated during the installation of the indicator light, thereby affecting the assembly efficiency of the fuse.

[0006] The present application provides a fuse cover that is easy to install and adopts the following technical solution:

[0007] A fuse cover that is easy to install includes a cover body and a sealing cover, wherein the cover body is provided with an installation cavity, and an insertion port that is connected to the outside and for inserting the sealing cover is provided on the opening edge of the installation cavity, guide strips are fixedly provided on opposite side surfaces of the sealing cover, and a guide groove for inserting and sliding the guide strips is provided on the inner wall of the installation cavity; an elastic plate is fixedly provided on the side of the cover body close to the insertion port, one side of the elastic plate abuts against the side of the sealing cover away from the installation cavity, a limiting protrusion is fixedly provided on the elastic plate, and a limiting sliding groove for inserting and sliding the limiting protrusion is provided on the sealing cover.

[0008] By adopting the above technical solution, after the sealing cover is slidably set on the cover body, the elastic plate is fixed on the cover body so that the limiting protrusion on the elastic plate is inserted into the limiting slide groove. Through the cooperation of the limiting protrusion and the limiting slide groove, the sliding of the sealing cover is limited, thereby reducing the possibility of the sealing cover directly sliding off the cover body during the reciprocating sliding process.

[0009] Optionally, a reinforcing ridge is provided on the side of the elastic plate away from the limiting protrusion, and the reinforcing ridge is perpendicular to the length direction of the limiting sliding groove.

[0010] By adopting the above technical solution, the structural strength of the elastic plate is improved due to the arrangement of the reinforcing ridges, and the service life of the elastic plate is also extended.

[0011] Optionally, the sealing cover is fixed with an anti-slip convex strip perpendicular to the length direction of the limiting sliding groove.

[0012] By adopting the above technical solution, when the user controls the sealing cover to slide back and forth, the user presses his fingers on the outer surface of the sealing cover. During this process, due to the setting of the anti-slip ridges, the friction between the worker's fingers and the outer surface of the sealing cover is increased, making it easier to control the sealing cover to slide back and forth relative to the cover body.

[0013] Optionally, a fixing block is fixedly provided at the end of the elastic plate away from the limiting protrusion, and the cover body is provided with a fixing groove on the inner edge of the opening of the insertion port for the fixing block to be embedded and fixed.

[0014] By adopting the above technical solution, during the installation process of the elastic plate and the cover body, the fixing block on the elastic plate is embedded and fixed into the inside of the fixing groove, thereby completing the installation of the elastic plate and improving the installation efficiency of the elastic plate.

[0015] Optionally, an elastic clamping piece is provided on the fixing block, and a positioning groove for inserting the elastic clamping piece is provided on the inner wall of the fixing groove.

[0016] By adopting the above technical solution, when the fixing block is inserted into the fixing groove, due to the setting of the elastic clip and the positioning groove, the elastic clip on the fixing block is inserted into the positioning groove on the inner wall of the fixing groove, thereby improving the installation stability of the fixing block inside the fixing groove.

[0017] Optionally, a guiding slope is provided on the opening edge of the fixing groove.

[0018] By adopting the above technical solution, during the process of inserting the fixing block into the fixing groove, due to the provision of the guiding inclined surface, the fixing block can be inserted into the fixing groove more quickly along the guiding inclined surface.

[0019] Optionally, the elastic plate is a spring leaf, and the limiting protrusion and the elastic plate are integrally formed.

[0020] By adopting the above technical solution, the elastic plate can bend elastically to a certain extent, thereby ensuring the service life of the elastic plate; and the elastic plate and the limiting protrusion are integrally formed, so no additional process is required to fix the elastic plate and the limiting protrusion, thereby improving the overall processing efficiency.

[0021] Optionally, a limiting block is fixedly provided on the inner wall of the guide groove, and a limiting slot for inserting the limiting block is opened on the guide bar.

[0022] By adopting the above technical solution, due to the coordinated setting of the limit block and the limit slot, when the sealing cover completely blocks the opening of the installation cavity, the limit block is inserted into the corresponding limit slot, thereby improving the installation stability of the sealing cover in this state.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Due to the cooperation between the limiting protrusion and the limiting slide groove, after the sealing cover is slidably set on the cover body, the elastic plate is fixed on the cover body so that the limiting protrusion on the elastic plate is inserted into the limiting slide groove, which limits the sliding of the sealing cover and reduces the possibility of the sealing cover directly sliding off the cover body during the reciprocating sliding process.
