[0037] Specifically, the shape of the insulating portion 10 is, for example, a rectangle, a circle or other geometric shape, and can be adaptively changed according to the shape of the pole 40, which is subject to actual application, and the specific shape of the insulating portion 10 is not limited in the present application. The insulating portion 10 has a groove, and the groove is recessed from the side facing the pole 40 to the side away from the pole 40, that is, the side of the groove facing the pole 40 is open, and the open side of the insulating portion 10 covers the pole 40, and the pole 40 is located in the groove, which plays a role in protecting the pole 40.

[0038] Specifically, the first sub-fixing member 201 and the second sub-fixing member 202 can be arranged relatively parallel to each other along the first direction X, for example, and the shell 30 is located between the first sub-fixing member 201 and the second sub-fixing member 202. The first sub-fixing member 201 and the second sub-fixing member 202 are attached to the opposite sides of the battery shell 30 and are slidably connected to the insulating part 10, thereby increasing the weight of the insulating part 10 in the vertical direction, ensuring to a certain extent that the insulating part 10 is not easy to fall off the pole 40, thereby improving the safety of the battery during transportation.

[0039] In an optional embodiment of the present application, the insulating portion 10 includes a first insulating portion 101 and a second insulating portion 102, and the first insulating portion 101 and the second insulating portion 102 are both located between the first sub-fixing member 201 and the second sub-fixing member 202 and slide between the first sub-fixing member 201 and the second sub-fixing member 202 along the first direction X.

[0047] In an optional embodiment of the present application, a sliding groove 203 extending along the first direction X is respectively formed on the first sub-fixing member 201 and the second sub-fixing member 202 , and the sliding member 104 is disposed in the sliding groove 203 and can slide in the sliding groove 203 .

[0048] Specifically, the sliding groove 203 does not penetrate the first sub-fixing member 201 and the second sub-fixing member 202 along the first direction X, that is, the length of the sliding groove 203 along the first direction X is less than the length of the first sub-fixing member 201 and the second sub-fixing member 202 along the first direction X, and the sliding member 104 slides in the sliding groove 203 to prevent the sliding member 104 from slipping off the first sub-fixing member 201 and the second sub-fixing member 202.

[0049] In an optional embodiment of the present application, a ratio of the cross-sectional areas of the pole 40 and the insulating portion 10 along the second direction Y is (1-9):10.

[0050] Specifically, the height of the insulating portion 10 along the second direction Y is greater than the height of the pole 40 along the second direction Y, the length of the insulating portion 10 along the first direction X is greater than the length of the pole 40 along the first direction X, and the width of the insulating portion 10 is also greater than the width of the pole 40, that is, the cross-sectional area of ​​the insulating portion 10 along the second direction Y is greater than the cross-sectional area of ​​the pole 40 along the second direction Y, and the inner wall of the insulating portion 10 will not cause damage to the pole 40, and the insulating portion 10 plays a role in protecting the pole 40.

[0052] Exemplarily, the height of the first sub-fixing component 201 and the second sub-fixing component 202 along the second direction Y is less than the height of the shell 30 along the second direction Y. The height of the shell along the second direction Y is, for example, 60 mm. The height of the first sub-fixing component 201 and the second sub-fixing component 202 along the second direction Y can be, for example, 20 mm, but is not limited to this and is subject to actual application.

[0055] Exemplarily, the ratio of the lengths of the insulating part 10 and the fixing plate 20 along the first direction X may also be 1:1. The fixing plate 20 increases the weight of the insulating part 10 to a certain extent. The fixing plate 20 is located on opposite sides of the outer shell 30, and fixes the insulating part 10 on a surface of the outer shell 30 to prevent the pole protective cover from falling off the pole 40 during transportation.

[0058] Specifically, the limiting rod 204 is adapted to the relative position relationship between the first sub-fixing member 201, the second sub-fixing member 202 and the outer shell 30. The two ends of the two limiting rods 204 are respectively connected to the first sub-fixing member 201 and the second sub-fixing member 202. The outer shell is located between the three, further limiting the displacement of the pole protective cover and preventing the pole protective cover from falling off the pole 40 and the outer shell 30.

[0059] Furthermore, the limiting rod 204 is, for example, an elastic member. In order to protect the housing 30 , a layer of soft silicone may be coated on the elastic member. The limiting rod 204 fixes the first sub-fixing member 201 and the second sub-fixing member 202 on the housing 30 .
