[0032] The preferred embodiments of this disclosure are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure. Furthermore, the embodiments and features in the embodiments of this disclosure can be combined with each other without conflict.

[0033] like Figures 1 to 6 As shown, this article provides a preferred embodiment of an automotive battery fuse box for connecting the positive terminal of the battery (not shown) and the positive terminal of the wiring harness (not shown). It includes: a fuse box cover 10, a box body 30, a battery positive terminal 40, a first busbar 50, and at least one fuse piece 60. The fuse box cover 10 is snap-fitted to the box body 30. The box body 30 has at least one mounting groove 301, and the fuse piece 60 is disposed within the mounting groove 301. One end of the wire 60 is connected to the positive terminal of the wire harness, and the other end is riveted to the first busbar 50. An elastic locking arm 302 is provided on the side wall of the mounting groove 301 at the position corresponding to the other end. A locking protrusion 303 is provided on the side of the locking arm, which locks the fuse 60. The first busbar 50 is also provided with a bending part 501, which extends out of the housing 30 and is connected to the positive terminal 40 of the battery. The positive terminal 40 of the battery is connected to the positive terminal of the battery.

[0034] Specifically, from Figure 2 As can be seen, the elastic locking arm 302 is formed from bottom to top on the side wall of the mounting groove 301. That is, the bottom of the elastic locking arm 302 is integrated with the side wall of the mounting groove 301, and the top of the elastic locking arm 302 is a free end. In this way, during the process of installing the fuse piece 60 into the housing 30, the elastic locking arm 302 can swing slightly so that the locking protrusion 303 on it can lock the fuse piece 60.

[0035] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, there are multiple fuse pieces 60 and multiple mounting slots 301. The first busbar 50 is provided with multiple riveting connections. Each fuse piece 60 is riveted to each riveting connection and then installed in the corresponding mounting slot 301. Preferably, the fuse piece 60 is a slow-blow fuse of 30A-200A. More specifically, it can be understood that a retaining protrusion 303 can be provided on the opposite sidewall of each mounting slot 301 to retain the fuse piece 60.

[0036] In some embodiments, such as Figure 4 As shown, one end of the fuse piece 60 is connected and fixed to the positive terminal (not shown) of the wire harness via a screw assembly.

[0037] Specifically, such as Figure 4 As shown, the screw-on assembly includes a bolt 70 and a nut (not shown in the figure). The bolt 70 is installed in the mounting groove 301. After the bolt 70 passes through the connection holes of the fuse piece 60 and the positive terminal of the wire harness in sequence, the nut is locked to the bolt 70. Thus, one end of the fuse piece 60 is screwed to the positive terminal of the wire harness, and the other end is riveted to the first busbar 50.

[0038] In some embodiments, such as Figure 2 As shown, the bottom wall of the mounting groove 301 is provided with a limiting rib 304 connecting the opposite side wall of the mounting groove 301, and a first limiting protrusion 305 disposed opposite to the limiting rib 304. The head of the bolt 70 is engaged between the first limiting protrusion 305 and the limiting rib 304. Thus, the horizontal displacement of the head within the mounting groove 301 can be restricted.

[0039] In some embodiments, such as Figure 2As shown, a second limiting protrusion 306 is provided on the side wall of the mounting groove 301 at a position corresponding to the head. The second limiting protrusion 306 has a gap with the bottom wall of the mounting groove 301, and the second limiting protrusion 306 is used to limit the displacement of the head along the height direction of the side wall of the mounting groove 301. As a result, the bolt 70 can be stably installed on the housing 30, further ensuring a secure connection between the first busbar 50, the fuse 60, and the positive terminal of the wiring harness, thus guaranteeing the stability of the electrical connection of the battery fuse box.

[0040] Preferably, such as Figure 2 As shown, a spring piece 307 is provided on the bottom wall of the mounting groove 301, and a first limiting protrusion 305 is provided at the free end of the spring piece 307.

[0041] In some embodiments, such as Figure 2 , Figure 5 and Figure 6 As shown, the bottom wall of the mounting groove 301 is provided with a positioning hole 308, which is used to accommodate the part S of the fuse piece 60 that protrudes from the first busbar 50 after being pressed and riveted with the first busbar 50.

[0042] In some embodiments, the battery fuse box further includes a battery positive terminal cover 20, which is hinged to the fuse box cover 10. This covers the battery positive terminal 40, providing dust protection.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this disclosure.

Therefore, if these modifications and variations to the embodiments of this disclosure fall within the scope of the claims of this disclosure and their equivalents, this disclosure is also intended to include these modifications and variations.
