First, the two auxiliary connecting tubes 2 are inserted into the main connecting tube 1. Since the fixed tubes 201 are arranged at the upper and lower positions of the auxiliary connecting tubes 2, after fixing The elasticity of the spring 202 in the tube 201 will drive the pressing head 204 to move, so that the pressing head 204 is stuck in the socket 203 of the main connecting tube 1, thereby directly limiting and fixing the two sub-connecting tubes 2. When the sub-connecting tube 2 and the insulated copper tube busbar 101 need to be removed, the pressing head 204 can be pressed to make the pressing head 204 pass through the spring 202 and enter the main connecting tube 1, so as to directly take out the sub-connecting tube 2, and conveniently disassemble and assemble the sub-connecting tube 2 and the main connecting tube 1, which solves the connection structure of the traditional copper tube busbar, which requires rotating the fixing bolts 301 and nuts to disassemble and assemble the copper tube busbar, which will waste a lot of time. In addition, a tool for tightening the bolts is also required, which is a very inconvenient technical problem.

[0023] For details, see Figure 2 A plurality of fixing bolts 301 are passed through the upper and lower ends of the auxiliary connecting tube 2 , and the plurality of fixing bolts 301 are threadedly connected to the screw holes in the auxiliary connecting tube 2 .

[0027] When using a copper tube busbar connection structure, first insert the two secondary connection tubes 2 into the main connection tube 1. Since the fixing tubes 201 are arranged at the upper and lower positions of the secondary connection tube 2, the elasticity of the spring 202 in the fixing tube 201 will drive the pressing head 204 to move, so that the pressing head 204 is stuck in the insertion hole 203 of the main connection tube 1, thereby directly limiting and fixing the two secondary connection tubes 2. When the secondary connection tube 2 and the insulated copper tube busbar 101 need to be removed, the pressing head 204 can be pressed to make the pressing head 204 enter the main connection tube 1 through the spring 202, thereby directly removing the secondary connection tube 2. The auxiliary connecting tube 2 is taken out, and the auxiliary connecting tube 2 and the main connecting tube 1 can be conveniently disassembled and assembled. The fixing bolt 301 can be used to screw into the auxiliary connecting tube 2. Since the mesh cover 205 and the silica gel desiccant 206 are arranged inside the fixing bolt 301, the silica gel desiccant 206 can be used to absorb moisture around the insulated copper tube busbar 101, thereby avoiding the moisture from corroding the insulated copper tube busbar 101. A DFC anti-condensation cotton board 302 is arranged in the fixing ring 3. The DFC anti-condensation cotton board 302 can assist in absorbing moisture in the main connecting tube 1, further improving the dehumidification effect.
