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.
