Problems solved by technology

[0002] The existing pipe bus connection method is mainly to insert an open conductive metal sleeve matching the outer diameter of the conductive pipe bus conductor at the connection part of the conductive pipe bus bar, and then insert a non-magnetic open stainless steel sleeve on the surface of the open conductive metal sleeve and place the stainless steel The axial opening of the sleeve is completely welded. In this connection method, the stainless steel sleeve is completely welded, the open conductive metal sleeve of the inner layer is not welded, and the open conductive metal sleeve of the inner layer is connected to the bus bar of the conductive pipe, and the open conductive metal sleeve of the inner layer is The connection with the stainless steel sleeve cannot be fixed by welding. During the installation process, especially during the installation process of turning or corners, the pipe busbar and the open conductive metal sleeve will become loose, or even disengage, and the stability is not enough.
In addition, the outer surface of the existing pipe busbars is equipped with a shielding insulation layer, so because there is a gap at the opening of the open conductive metal sleeve, water vapor is easy to enter, which affects the insulation effect of the shielding insulation layer
Therefore, the existing pipe busbar connectors cannot meet the requirements of good insulation effect, high surface smoothness and stable welding joints, and cannot meet the needs of the prior art

Embodiment 1

[0025] Such as figure 2 As shown, a conductive sleeve 2 matching the outer diameter of the copper bus conductor 3 is placed at the connecting part of the two copper bus bars. The material of the conductive sleeve 2 is the same as that of the copper bus conductor 3. The corresponding positions of the bus conductors 3 are welded with the same material of solder, and then the opening 1 of the axial opening 1 of the conductive sleeve 2 is welded with the solder of the same material as the copper bus conductor 3, so that the connecting part of the copper bus is closely connected with the conductive sleeve 2 Connect as one. Finally, the welding joint shall be polished and smoothed, and then shielded and insulated.

Embodiment 2

[0027] Such as figure 2 As shown, a conductive sleeve 2 matching the outer diameter of the aluminum bus conductor 3 is placed at the connecting part of the two aluminum busbars. The material of the conductive sleeve 2 is the same as that of the aluminum busbar conductor 3. The solder of the same material is used for welding between the corresponding positions of the bus conductor 3, and then the opening 1 of the axial opening 1 of the conductive sleeve 2 is welded with the same material as that of the aluminum bus conductor 3, so that the connecting part of the aluminum bus is closely connected with the conductive sleeve 2 Connect as one. Finally, the welding joint is polished and smoothed, and then shielded and insulated.

Embodiment 3

[0029] Such as figure 2 As shown, the conductive sleeve 2 matching the outer diameter of the alloy bus conductor 3 is placed at the connecting part of the two alloy bus bars for large current. The material of the conductive sleeve 2 is the same as that of the alloy bus conductor 3. The conductive sleeve 2 The solder of the same material is used for welding between the two end edges of the alloy bus conductor 3 and the corresponding positions of the alloy bus conductor 3 . , and then weld the opening 1 at the axial opening 1 of the conductive sleeve 2 with the same material as the alloy busbar conductor 3, so that the connecting part of the alloy busbar and the conductive sleeve 2 are tightly connected as a whole. Finally, the welding joint is polished and smoothed, and then shielded and insulated.
