[0024] Example

[0025] The present embodiment provides a shell of a car battery and a terminal protection cover adapted therefor, wherein a terminal 2 is connected to the battery shell 1, and the terminal 2 and the shell are connected by a fastener 3, and the terminal protection cover comprises a first protective cover 4 sleeved on the terminal 2, a second protective cover 41 sleeved on the fastener 3, and a connecting cover 42 for connecting the two, wherein the opening of the connecting cover 42 faces downward and is hollow inside, forming a space for wrapping the terminal 2 and the fastener 3, and an opening is provided on the first protective cover 4 for inserting an external cable and connecting to the terminal 2, and a strip groove 43 is provided at the opening to enable the first protective cover 4 to be folded outward to expose the terminal 2.

[0026] The above specific improvements are: Figure 1 and Figure 2 As shown, during the installation process, the terminal block is fixed to the shell by fasteners. The terminal block is used to connect with external wires. Most of the connections between the wires and the terminal block are not provided with a protective mechanism, which may cause the wires to separate from the terminal block. In order to avoid this technical problem, a terminal protection cover is added to the outside of the terminal block. The terminal protection cover includes a first protective cover sleeved on the terminal block, a second protective cover sleeved on the fastener, and a connecting cover for connecting the two. When connecting the wires and the terminal block, the first protective cover can be folded outward by hand to expose the terminal block. After the connection between the terminal block and the wire is completed, the first protective cover can be folded inward to wrap the connection position between the terminal block and the wire. Through the setting of the strip groove, the operator can more conveniently fold the first protective cover outward from the strip groove. Through the setting of the connecting cover, the first protective cover and the second protective cover can be connected, which is convenient for the installation of the first protective cover and the second protective cover.

[0027] On the basis of the above embodiment: at least one positioning block 5 is disposed inside the connection cover 42 and contacts the upper end surface of the shell 1 . The positioning block 5 is disposed on the inner side wall of the connection cover 42 .

[0028] The above specific improvements are: Figure 3 As shown, two positioning blocks that abut against the upper end surface of the shell are arranged inside the connecting cover. The positioning blocks are located on the inner side surface of the connecting cover, the upper ends of the positioning blocks are fixed to the connecting cover, and the lower ends thereof abut against the shell, thereby forming a sealed space in the area wrapped by the connecting cover to prevent dust from entering.

[0029] On the basis of the above embodiment: the top of the second protective cover 41 is a sealing structure.

[0030] The above specific improvement is: a sealing structure is formed above the second protective cover, which can effectively prevent dust from reaching the wiring terminals and the fastening nails.

[0031] On the basis of the above embodiment: the connecting cover 42 includes a first protective end 421 connected to the first protective cover 4, a second protective end 422 connected to the second protective cover 41, and a connecting end 423 arranged between the first protective end 421 and the second protective end 422, the positioning block 5 is located on the inner wall of the connecting end 423, the upper end of the connecting cover 42 is connected to the first protective cover 4 and the second protective cover 41, and the lower end thereof is in contact with the upper end surface of the battery shell 1.

[0032] The above specific improvements are: Figure 2 As shown, the connecting cover includes a first protective end arranged at the lower end of the first protective cover, a second protective end at the lower end of the second protective cover, and a connecting end between the first protective end and the second protective end. The three are covered on the shell and wrap around the wiring terminals and fasteners. One can play a dust-proof role for the wiring terminals and fasteners, and the other can protect the connection between the wiring terminals and the wires to prevent the two from being disconnected.

[0033] On the basis of the above embodiment: an annular convex edge 51 is provided at the opening direction of the first protective cover 4 for convenient gripping by fingers.

[0034] The above specific improvements are: Figure 2 and Figure 3 As shown, an annular convex edge is provided in the opening direction of the first protective cover. After the connecting terminals and the wires are connected, when the folded-outward part is reset, the annular convex edge can be grasped by hand and folded inward to achieve quick reset. The setting of the annular convex edge can provide a gripping space for the inward folding.

[0035] On the basis of the above embodiment: the battery housing 1 includes a first positioning bar 6 and a second positioning bar 7 respectively fixed on both sides of the connecting end 423 , and a third positioning bar 8 for abutting against the second protective end 422 is arranged on the side of the second protective cover 41 .

[0036] On the basis of the above embodiment: the third positioning bar 8 is provided with an arc groove 81 which fits with the second protective cover 41 .

[0037] The above-mentioned specific improvements are as follows: in order to fix the position of the terminal protective cover, a first positioning strip and a second positioning strip fixed on both sides of the connecting end are provided on the battery housing, and a third positioning strip is provided on the side of the second protective cover. The first positioning strip and the second positioning strip are used to fix the terminal protective cover longitudinally, and the third positioning strip is used to fix the terminal protective cover laterally. In this way, the position of the column terminal protective cover can be fixed in all directions, and the arc groove provided on the third positioning strip is used to avoid the second protective end and can quickly locate the installation position of the second positioning end.

[0038] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
