The insulating column assembly 320 is spaced apart from the insulating blocks 310, and is preferably disposed between two insulating blocks 310, i.e., in the middle of the sub-copper bar 410. The main function of the insulating column assembly 320 is to support the sub-copper bar 410, prevent the middle part of the sub-copper bar 410 from deforming under the action of gravity, and simultaneously play an insulating role.

The insulating post assembly 320 includes a first insulating post member 321, a second insulating post member 322, a third insulating post member 323, and a set screw 324. The first insulating column member 321, the second insulating column member 322 and the third insulating column member 323 are arranged at the upper end and the lower end of each sub copper bar 410 in a segmented manner, so as to play a role in positioning and insulating each sub copper bar 410. It will be appreciated that the insulating post assembly 320 is preferably made of a material having a certain hardness and having insulating properties.

For convenience of describing the relative positions of the insulating column sub-elements and the sub-copper bars 410, the embodiment takes three sub-copper bars 410 as an example for description. Namely, the bottom plate 100, the first sub copper bar 410, the second sub copper bar 410 and the third sub copper bar 410 are sequentially arranged from bottom to top.

The second insulating column 322 is generally cylindrical as a whole, and has stepped second mounting portions 3221 at both upper and lower ends. Because the diameter of the second mounting portion 3221 is smaller, the second mounting portion 3221 at the lower end may sequentially penetrate through the second sub-copper bar 410 and the first insulating pillar 321. The end of the second mounting portion 3221 is provided with a threaded hole, and the threaded hole is matched with a thread formed on the second base plate mounting post 120, so as to fix the relative positions of the base plate 100, the first insulating post member 321, the first sub copper bar 410, the second insulating post member 321, and the second sub copper bar 410.

The second mounting portion 3221 at the top end is sleeved with a third sub-copper bar 410, and a third insulating column 323 is disposed at the top end of the third sub-copper bar 410. The third insulating column 323 has a substantially cylindrical shape as a whole, and a stepped third mounting portion 3231 is provided at a lower end thereof. Due to the small diameter of the third mounting portion 3231, the third mounting portion 3231 can be inserted into the second mounting portion 3221 of the third sub-copper bar 410 and the second insulating column 322 at the top end.

The fixing screw 324 passes through the third insulating column 323 and the third sub-copper busbar 410, and is in threaded connection with the threaded hole at the upper end of the second mounting portion 3221.

The third insulating column 323 has a structural design to isolate the fixing screw 324 from the third sub copper bar 410 and to support the top cover of the product.
