Description

Technical Field

[0001] This invention relates to the field of current fuse box technology, specifically a combined low-current fuse box. Background Technology

[0002] The modular low-current fuse box is an important device for automotive circuit protection. It effectively prevents electrical damage, fires, and other safety accidents caused by circuit overload, short circuits, and other faults. Furthermore, the modular low-current fuse box possesses several advanced features, such as intelligent control, programmable protection, high efficiency and energy saving, and low power consumption. These features can significantly reduce energy consumption and environmental pollution in automotive circuits, while improving overall vehicle performance and lifespan. In the future, the modular low-current fuse box will continue to play a vital role and become a mainstream product for automotive circuit protection.

[0003] However, traditional low-current fuse boxes are mostly open boxes with multiple fuses installed inside. When one fuse blows, the high temperature generated can easily affect other fuses, reducing their lifespan. Furthermore, installing or removing a blown fuse usually requires disassembling the entire cover, causing inconvenience for workers and allowing dust to fall into the box, affecting the normal operation of other fuses. Therefore, technical improvements are urgently needed. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a combined low-current fuse box, which solves the problems of poor protection performance and easy impact on the fuse body during use of traditional low-current fuse boxes. It also solves the problem that traditional low-current fuse boxes often require the entire cover to be removed during installation or when disassembling a blown fuse body, causing inconvenience to workers.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a combined low-current fuse box, comprising a base plate and multiple sliding plates. A mounting box is fixedly connected to the middle of the upper surface of the base plate. Multiple first through holes are provided on one side of the mounting box, and multiple second through holes are provided on the side of the mounting box away from the first through holes. Two first limiting grooves are provided at the rear end of each of the first through holes. Multiple baffles are fixedly connected inside the mounting box. Two second limiting grooves are provided on the outer wall of the front end of each baffle. Multiple snap-fit ​​plates and sliding rods are fixedly connected to the bottom surface of the mounting box. Two third limiting grooves are provided on the upper surface of each snap-fit ​​plate, and a fourth limiting groove is provided on one side of each snap-fit ​​plate. Sliding grooves are provided in the middle of the bottom surfaces of the multiple sliding plates. A first limiting block is fixedly connected to the middle of the upper surface of each sliding plate. Connecting plates are fixedly connected to the front and rear ends of the upper surface of each sliding plate. The sliding grooves are slidably connected to the outer wall of the sliding rods. The first limiting blocks are slidably connected inside the fourth limiting grooves. The connecting plates are slidably connected inside the third limiting grooves.

[0008] The upper surface of the connecting plate is fixedly connected to the fuse body, and the middle of both sides of the fuse body is fixedly connected to the connecting pin. The upper and lower parts of the outer wall of the rear end of the fuse body are fixedly connected to the second limiting block. The second limiting block is slidably connected inside the first limiting groove and the second limiting groove. The upper end of the mounting box is provided with a cover plate. The middle of the cover plate is provided with a mounting groove. The mounting groove is provided with a mounting plate. The lower surface of the mounting plate is fixedly connected to a drying plate.

[0009] The above technical solution facilitates the quick installation and removal of the sliding plate and fuse body by the snap-fit ​​plate and sliding rod. This allows for quick replacement of the fuse body when it is damaged, while also reducing the likelihood of shaking when the fuse body is installed. This improves the compactness and stability of the low-current fuse box during use.

[0010] Preferably, a first fixing threaded hole is provided in the middle of the bottom surface of the first limiting groove, a plurality of fixing through holes are provided on one side of the upper surface of the mounting box, a second fixing threaded hole is provided on one side of the upper surface of the second limiting block, and a fixing long bolt is provided inside the first fixing threaded hole, the second fixing threaded hole and the fixing through hole.

[0011] The above technical solution, which uses a long fixing bolt to fix the fuse body with the fixing through hole, the first fixing threaded hole, and the second fixing threaded hole, allows workers to fix the cover plate, the mounting box, and the fuse body simultaneously. This improves the overall stability of the device and further ensures the stability of the fuse body installation. When one fuse body becomes stuck, it can be removed simply by unscrewing the corresponding long fixing bolt without affecting other fuse bodies, thus facilitating replacement work for workers.

[0012] Preferably, a heat insulation plate is fixedly connected to the middle of each of the baffles;

[0013] The above technical solution effectively insulates the fuse by using a heat insulation board, thus preventing damage to other fuses when one fuse body is damaged.

[0014] Preferably, a connecting rod is fixedly connected to the outer wall of the rear end of the sliding plate, and a handle is fixedly connected to the end of the connecting rod away from the sliding plate.

[0015] The above technical solution allows workers to easily install and remove the sliding plate and fuse body via a handle.

[0016] Preferably, the mounting plate and the cover plate are fixedly connected by bolts.

[0017] The above technical solution, which uses bolts for fixing, facilitates the installation and disassembly of the mounting plate by the workers.

[0018] Preferably, the fixed long bolt is threadedly connected to the first fixed threaded hole and the second fixed threaded hole respectively.

[0019] Preferably, the mounting box and the cover plate are fixedly connected by bolts.

[0020] The above technical solution, which uses bolts for fixing, facilitates the installation and disassembly of the cover plate by workers.

[0021] Preferably, mounting holes are provided at all four corners of the upper surface of the base plate.

[0022] Working Principle: This low-current fuse box, through its snap-fit ​​plate and sliding rod, facilitates quick installation and removal of the sliding plate and fuse body. This allows for rapid replacement of any damaged fuse body, while also minimizing wobbling during installation, enhancing the compactness and robustness of the fuse box. Furthermore, the use of long bolts and threaded connections to the through holes, first threaded hole, and second threaded hole allows for simultaneous securing of the cover plate, mounting box, and fuse body, further improving the overall stability of the device. This design further ensures the secure installation of the fuse body. When one fuse body becomes stuck, it can be removed simply by unscrewing the corresponding fixing bolts without affecting other fuse bodies, thus facilitating replacement work. The inclusion of baffles and heat insulation plates provides safety protection, preventing the blown fuse body from affecting others. Furthermore, the removable drying plate effectively improves the dryness inside the mounting box, reducing oxidation and significantly extending the fuse body's lifespan.
