Pipe bus connector

Abstract

The invention discloses a pipe bus connector, which is used for connecting copper, aluminum or alloy buses and is a conductive sleeve (2) made of the same material as a bus conductor (3), wherein the conductive sleeve (2) is sleeved at a bus connecting part, the peripheral wall of the conductive sleeve is provided with an axial opening (1), the inside diameter of the conductive sleeve (2) is matched with the outside diameter of the bus conductor (3), and the axial opening (1) is welded by solder made of a the same material as the bus conductor (3) to ensure that the bus connecting part is closely connected with the conductive sleeve (2) into a whole. The pipe bus connector has the advantages of simple structure, small contact resistance, direct welding of the opening of the conductive sleeve, no clearance, no steam entering, good insulating effect, difficult influence by outside, and firm welded junction.

Description

technical field [0001] The invention relates to a busbar connector for conductive pipes, in particular to a connector suitable for connecting busbars of conductive pipes for transmitting large power frequency currents, in particular to a busbar connector for pipes. Background technique [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 ...

[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
