It should be noted that, the fuse box 100 and the storage battery (not shown) of the present application are separately disposed, and do not form direct contact, so that the connection flexibility is high and the versatility is good compared with the positive electrode fuse box in the related art.

Referring to fig. 1, in some embodiments, the housing 10 is flat.

In this way, the height of the safe 100 is made low, thereby saving the installation space of the safe 100.

Specifically, in one embodiment, as shown in fig. 1, the housing 10 is flat, so that the internal space of the fuse box 100 is long and narrow, so that the fuse 30 can be safely wired inside the fuse box 100, and meanwhile, the installation space is saved, thereby being convenient for installation and fixation.

It will be appreciated that the height of the cartridge 100 is small relative to the length and width of the cartridge 100, thereby saving space in the longitudinal direction of the cartridge 100 and reducing installation costs.

In certain embodiments, the housing 10 has a length, a width, and a height, wherein the length is L, the width is W, and the height is H, and the housing 10 satisfies at least one of the following conditions:

L:H>2；

W:H>2。

Thus, the fuse box 100 is formed to be flat and small in size, thereby saving installation space and reducing cost.

Specifically, in one embodiment, in the case where the ratio of the length of the housing 10 to the height of the housing 10 is greater than 2, that is, L: H >2, the difference in the ratio of the length and the height of the housing 10 is large, so that the housing 10 has a substantially flat structure, thereby making the height of the housing 10 small and the longitudinal space occupied is small.

For example, in some examples, the ratio of the length to the height (L: H) of the housing 10 may be any one of 3, 4, 5, 6, 8, or more than 2, without being particularly limited thereto.

Similarly, in one embodiment, where the ratio of the width of the housing 10 to the height of the housing 10 is greater than 2, i.e., L: H >2, the ratio of the width to the height of the housing 10 is greater, such that the housing 10 is substantially flat, such that the thickness of the housing 10 is thinner and the height is smaller.

For example, in some examples, the ratio of the width to the height (W: H) of the housing 10 may be any one of 3, 4, 5, 6, 8 or more than 2, without being particularly limited thereto.

In summary, the housing 10 at least needs to satisfy one condition that the ratio of the length to the height is greater than 2 or the ratio of the width to the height is greater than 2, and can satisfy two conditions simultaneously, so that the housing 10 can be ensured to form a flat structure, thereby saving the installation space of the fuse box 100 and improving the installation efficiency.

In one embodiment, the housing 10 preferably has a length, width and height of 137.7mm, 135.7mm and 44.7mm, respectively, such that the ratio of length, width and height is about 3:3:1, thereby forming the cartridge 100 in a flat configuration, such that the volume of the cartridge 100 is small and the production and installation costs are low.

In one embodiment, the number of the second connection members 151 is matched with the number of the first connection members 141, for example, the number of the second connection members 151 may be 4 to be disposed around the edge of the base 15, thereby improving the connection stability of the base 15.

That is, as shown in fig. 1, the first and second connection members 141 and 151 are fastened and connected such that the outer peripheral edges of the top cover 14 and the base 15 are tightly connected, thereby improving the protection performance of the safe 100.
