Embodiment Construction
[0010] The present invention will be further described below in conjunction with drawings and embodiments.
[0011] exist figure 1 Among them, a battery cover 3, a rectangular sealing ring 4, a washer 5, and a nut 6 are sequentially installed on the battery pole 1 embedded with copper-zinc parts 2. The battery pole 1, the nut 6 and the battery cover 3 form a cavity, and the diameter of the inner hole of the nut 6 should be larger than the diameter of the battery pole, so that a section of annular ring communicating with the cavity is formed between the battery pole 1 and the nut 6 Gap, the width of the gap is 2 ~ 5mm, and the height is 3 ~ 10mm; the pole glue 7 is filled in the cavity and the annular gap to form a glue seal. Since the present invention increases the gap, the sealing height of the glue seal is increased by The original h1 is increased to the current h2, which greatly enhances the sealing effect.
[0012] In addition, the inner hole of the nut 6 is a two-layer...
