The structure of each component in this embodiment will be described in detail.

As shown in fig. 2 to 6, the projected shape of each seal rib 23 in the axial direction of the electrode hole 211 is the same. Specifically, in this embodiment, fig. 2-4 show an implementation manner of the sealing ribs 23, where the axial direction of the electrode hole 211 is the same as the axial direction of the main body 21, and in this embodiment, ten sealing ribs 23 are disposed in the electrode hole 211 along the hole wall in a surrounding manner, where each sealing rib 23 is in an independent ring shape, and is disposed at equal intervals along the axial direction of the electrode hole 211, and the difference between the lengths of the adjacent sealing ribs 23 protruding from the hole wall of the electrode hole 211 is set to be the same, so that the elasticity of each sealing rib 23 changes uniformly. By the arrangement of ten seal beads 23, when the electrode 4 is fitted into the electrode hole 211, sealability between the electrode 4 and the electrode hole 211 can be ensured. In some embodiments, two, three or four sealing ribs 23 may be disposed around the hole wall in the electrode hole 211, and the number of the sealing ribs 23 may be more than ten.

In some embodiments, the closer to the bottom, the larger the difference between the lengths of the walls of the adjacent sealing ribs 23 protruding from the electrode hole 211 may be, so that the higher the rate of elasticity of the sealing ribs 23 decreases from the top toward the bottom, and thus, the degree of adhesion between the sealing ribs 23 near the bottom and the outer side wall of the electrode 4 may be enhanced, so as to improve the sealing performance.

It should be understood that, based on the above design concept, the number of the sealing ribs 23 and the length of the sealing ribs 23 protruding from the wall of the electrode hole 211 may be adaptively set according to practical situations, so long as the elasticity of each sealing rib 23 is ensured to be lower and lower in the direction from top to bottom.

In some embodiments, the cross-sectional shape of each spacer 212 may be set to be different, so long as the axial projection of the upper spacer 212 is guaranteed to fall within the projection of the lower spacer 212. In some embodiments, the axial thickness of each spacer segment 212 may be the same, or the axial thickness of each spacer segment 212 may decrease sequentially in a top-down direction.
