Description

Technical Field

[0001] This utility model relates to the field of automotive electrical components technology, and in particular to fuse box assemblies. Background Technology

[0002] As the core power distribution unit of a vehicle's electrical system, the automotive fuse box undertakes key functions such as power distribution, overload protection, and fault isolation. Traditional fuse boxes mainly consist of a housing, busbar structure, relay slots, and fuse / circuit breaker mounting positions. Their technological development has always revolved around the reliability of electrical connections, the compactness of spatial layout, and the ease of maintenance.

[0003] In the prior art, such as the automotive fuse box body disclosed in CN222320171U, there is a fuse box body and a first terminal insertion area disposed within the fuse box body. The first terminal insertion area includes single-terminal plugs and double-terminal plugs. The single-terminal plugs are located on both sides of the first terminal insertion area, and at least one row of double-terminal plugs is arranged between the single-terminal plugs on both sides. The single-terminal plugs and double-terminal plugs, and / or two adjacent sets of double-terminal plugs, are separated by a shared first partition. The two sets of terminal supports on both sides of the first partition have a face-to-face structure, and the two sets of terminal supports on both sides of the first partition are used to support a set of terminals to be inserted. The two slots located on both sides of the first partition and used to insert the set of terminals to be inserted are referred to as slot groups. This utility model improves the compactness of the main structure, significantly reduces the volume of the fuse box body, and significantly saves manufacturing costs.

[0004] The existing technology has the following technical bottlenecks:

[0005] Busbars rely on mechanical fastening or welding for installation, which results in low assembly efficiency and makes it difficult to guarantee long-term contact reliability.

[0006] The functional module layout is poor, and the mounting positions for relays / fuse / circuit breakers lack integrated design, resulting in poor space utilization.

[0007] Therefore, it is necessary to invent a fuse box assembly to solve the above problems. Utility Model Content

[0008] The purpose of this invention is to provide a fuse box assembly to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a fuse box assembly, including a box body, a busbar fixedly disposed inside the box body, a plurality of fuse locking plates and fuse circuit breaker locking plates being connected to the upper surface of the busbar, and the plurality of fuse locking plates and fuse circuit breaker locking plates being disposed on the upper surface of the box body, the busbar being configured with a "∩" shaped structure, and a circular hole penetrating one end of the busbar, and a terminal block being inserted into the circular hole, a slot penetrating one end of the lower surface of the box body, and a fixing seat being inserted into the slot, the top end of the fixing seat being abutted against one end of the lower surface of the busbar, a plurality of ten-wire socket sleeves being fixedly disposed on the upper surface of the box body, a relay locking plate being disposed above the plurality of ten-wire socket sleeves, and the plurality of relay locking plates being disposed on the upper surface of the box body, a wire groove being opened at one end of the outer side wall of the box body, and the wire groove being disposed on one side of the fixing seat.

[0010] Preferably, both ends of the box are fixedly provided with card holders, and the card holders are fixedly provided with elastic card blocks inside.

[0011] Preferably, both ends of the box are fixedly provided with mounting bases, and the mounting bases are provided with mounting holes through the middle.

[0012] Preferably, both sides of the box body are fixedly provided with protrusions, and the bottom of the outer side wall of the protrusions is provided with an inclined structure.

[0014] Preferably, each of the four corners of the upper surface of the plurality of ten-wire socket sheaths is fixedly provided with a retaining plate, and the relay locking plate is located on the inner side of the retaining plate.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] This utility model utilizes a "∩"-shaped busbar structure combined with a bottom slot-type mounting base design to significantly increase the conductive cross-sectional area while forming a three-dimensional heat dissipation channel. The plug-in connection structure between the busbar and the terminal block achieves double-stage locking via a wire-pressing nut. The composite mounting groove formed by the ten-wire socket sheath and the locking plate, along with the elastic limiting structure of the relay locking plate, enables tool-free and rapid replacement of relays of different specifications, effectively improving space utilization. Furthermore, the integrated wire channel achieves physical isolation between high and low voltage wire harnesses, reducing electromagnetic interference between harnesses while guiding them. The two-stage positioning system, consisting of elastic locking blocks and inclined protrusions on both sides of the box, further improves assembly efficiency. Combined with the hot-swappable guide structure for the fuse locking plate, the installation and replacement time for individual components is further shortened, effectively solving the technical problems of low space utilization, unstable contact impedance, and low maintenance efficiency inherent in traditional solutions.
