In this embodiment, since the inter-post reinforcing ribs 120 and the post holes 110 are both centrosymmetric with respect to the intersection point of two diagonal lines of the cover plate, when the positive post and the negative post need to pass through the cover plate 100, the positive post and the negative post can pass through any post hole 110 at will, and it is not necessary to particularly correspond the positive post to the positive post hole 111 and the negative post to the negative post hole 112, which reduces the assembly time and improves the production efficiency.
