The distance between the top side beam and the end pole base 7, the middle pole 9 and the negative electrode bus bar 8 can be increased by the two oblique sides, and even if a grid grows up, the top side beam cannot be contacted with the end pole base 7, the middle pole 9 and the negative electrode bus bar 8, so that the problem of short circuit caused by the long grid is solved, and the service life of the storage battery is prolonged.

In some embodiments, the inclination angle of the left side section 12 is 11-15 °, and the left side section 12 is set to be different inclination angles according to the batteries of different specifications, so that the area on the left side of the top side beam forms equidistant gaps with the terminal post base 7, the middle post 9 and the negative bus bar 8.
