Of course, the cross section of the groove 213 along the second direction Y may be provided as a rectangle, but the groove opening may be provided as small. In this case, the first end 221 is configured to fit the dovetail groove, that is, the first end 221 has a trapezoidal cross-sectional shape along the second direction Y.

So set up, can avoid first connecting portion 22 to deviate from support body 21 in second direction Y to first connecting portion 22 has been increased with support body 21's fastness of connection. Moreover, since a pulling force or a pushing force along the second direction Y and toward a side away from the holder body 21 needs to be applied to the second end portion 222 of the first connecting portion 22 when the first connecting portion 22 and the holder body 21 are mounted or dismounted, the pushing force or the pulling force can be prevented from pulling out or pushing out the first end portion 221 from the groove 213.

In another exemplary embodiment of the present disclosure, referring to fig. 9, when the isolation plate structure 212 and the base 211 are separately provided, the first connection portion 22 may be fixedly connected to the isolation plate structure 212, specifically, the first connection portion 22 is provided at one side of the isolation plate structure 212 in the second direction Y, one surface of the first end portion 221 of the first connection portion 22 close to the isolation plate structure 212 is connected to one surface of the isolation plate structure 212 close to the first connection portion 22, and the first connection portion 22 and the isolation plate structure 212 may be integrally formed through a one-time injection molding process.

After the isolation plate structure 212 and the first connection portion 22 are mounted on the base 211, a gap is provided between the first connection portion 22 and the second connection portion 23, and the width of the gap may be equal to the thickness of the side wall of the fixing member 1 between the first connection portion 22 and the second connection portion 23, so as to ensure that a part of the side wall of the fixing member 1 is clamped by the first connection portion 22 and the second connection portion 23, and prevent the output electrode protection support 2 from moving in the second direction Y.

In the present exemplary embodiment, the second end 222 of the first connecting portion 22 is snapped outside the fixing member 1, so that the holder body 21 and the first connecting portion 22 are fixedly connected with the fixing member 1 in the first direction X. Specifically, referring to fig. 3, a clamping groove 13 is disposed on the outer side of the fixing element 1 in the second direction Y, and the clamping groove 13 may be a through hole penetrating through a side wall of the support body 21 away from the battery pack, or may be a blind hole. The card slot 13 may be configured to be elongated.

And the surface of the clamping platform 223 close to the support body 21 is set to be a plane, and of course, the surface of the clamping groove 13 matched with the surface of the clamping platform 223 close to the support body 21 is also set to be a plane.

Further, referring to fig. 2, 5, 7 and 9, the end surface of the second end portion 222 may be configured to be an inclined surface, and in the second direction Y, the distance between the end surface of the second end portion 222 and the fixing member 1 increases with the increase of the distance from the first end portion 221, so that a gap is formed between the end surface of the second end portion 222 of the first connecting portion 22 and the fixing member 1, when the first connecting portion 22 and the holder body 21 are removed, a worker may apply a pulling force or a pushing force along the second direction Y and to a side away from the holder body 21 to the second end portion 222 of the first connecting portion 22 through the gap, and then remove the clamping table 223 from the clamping groove 13, so that the output electrode protection holder 2 may be removed from the fixing member 1 along the first direction X, and the removal of the output electrode protection holder 2 is completed.

Of course, the end surface of the second end portion 222 may be a curved surface, may protrude toward the fixing member 1, or may be recessed toward the side away from the fixing member 1, as long as the distance between the end surface of the second end portion 222 and the fixing member 1 increases with the distance from the first end portion 221 in the second direction Y.

Furthermore, one surface of the clamping table, which is far away from the first end part, is provided with an inclined surface or a curved surface, and is coplanar with the end surface of the second end part; that is, in the second direction Y, the distance between the surface of the block facing away from the first end portion and the second connection portion 23 increases with the distance from the first end portion 221, so that a gap is formed between the surface of the block facing away from the first end portion and the second connection portion 23.

The area of the end face of the second end part is increased through the face, deviating from the first end part, of the clamping table, and pulling force or pushing force can be applied to the end face of the second end part by workers.

It should be noted that the coplanar surface includes not only a coplanar surface but also a coplanar curved surface; and are not perfectly coplanar but rather have some tolerance.

To increase friction, a pattern, score, or the like may also be provided on the end surface of the second end 222.

In the present exemplary embodiment, the second connecting portion 23 is fixedly connected to a side of the mount body 21 close to the mount 1, and the second connecting portion 23 is inserted into the mount 1 along the first direction X. A plurality of cavities 11 are arranged on the fixing member 1, and the second connecting portion 23 may be configured in a shape adapted to the cavities 11, for example, the cavities 11 are configured as rectangular solids, and the second connecting portion 23 is configured as a rectangular solid; the cavity 11 is configured as a triangular prism, and the second connection portion 23 is configured as a triangular prism.

The second connecting part 23 is in clearance fit in the cavity 11; namely, after the second connecting portion 23 is inserted into the cavity 11, the distance between the side surface of the second connecting portion 23 and the inner cavity surface of the cavity 11 is greater than or equal to 0, namely, the second connecting portion 23 and the inner cavity surface of the cavity 11 can be tightly attached to each other, and a gap can also be formed between the second connecting portion 23 and the inner cavity surface of the cavity 11, so that the fixing member 1 does not cut the second connecting portion 23 during the processes of removing and installing the output electrode protection support 2 for many times, and the second connecting portion 23 is prevented from being damaged. A clearance fit is a fit with a clearance (including a minimum clearance equal to zero).

The references to "parallel" and "perpendicular" in this application are not exactly parallel, perpendicular, but rather have some tolerance; for example, the included angle between the two is greater than or equal to 0 ° and less than or equal to 5 °, i.e., the two are considered to be parallel to each other; the angle between the two is equal to or greater than 85 ° and equal to or less than 95 °, i.e. the two are considered to be perpendicular to each other.
