Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, and in particular to a sealing structure at a connection of a bus duct. Background Art

[0002] Bus duct is a power distribution device that efficiently transmits current. It is particularly suitable for the economical and reasonable wiring needs of high-rise buildings and large-scale factories. The bus duct on the market includes an outer shell and a number of conductive copper bars arranged inside the outer shell, wherein the conductive copper bars are arranged parallel to each other and extend along the length direction of the outer shell. Since the bus duct is produced in sections during the production process, the conductive copper bars at both ends need to be exposed at the end position of the bus duct, and then the exposed conductive copper bars in the two sections of the bus duct are connected to each other through connectors to connect multiple sections of the bus duct into a whole. After the connection is completed, side panels need to be installed on both sides of the connector to serve as a partition from the outside, but the structural sealing of the side panels is poor. Utility Model Content

[0003] In order to solve the above technical deficiencies, the utility model provides a sealing structure for a bus duct connection, which can seal the connection of the bus duct when in use.

[0004] The utility model discloses a sealing structure for a busbar connection, comprising a rectangular shell and a plurality of conductive copper bars arranged inside the rectangular shell, wherein the conductive copper bars at two ends of the rectangular shell are exposed, sliding sleeves are arranged on the outer sliding sleeves at two ends of the rectangular shell, threaded holes are arranged on the peripheral side of the sliding sleeve at the end away from the conductive copper bar, fastening screws are arranged in the threaded holes, a rubber sleeve is arranged at the end of the sliding sleeve away from the conductive copper bar, one end of the rubber sleeve is sleeved on the sliding sleeve, and the other end of the rubber sleeve is sleeved on the rectangular shell, a connecting piece is arranged on the side of the end of the sliding sleeve close to the conductive copper bar, a connecting through hole is arranged on the connecting piece along the length direction of the rectangular shell, and a sealing ring is arranged at the end of the sliding sleeve close to the conductive copper bar.

[0005] When the above technical solution is in use, the exposed conductive copper bars at the ends of the two bus ducts are connected through a connector, and then the sliding sleeves on the two bus ducts are slid respectively to align the two sliding sleeves, and then the connecting parts on the two sliding sleeves are fixedly connected by bolts and nuts. At this time, the sealing ring is squeezed to seal the connection, and the rubber sleeve ensures the sealing between the sliding sleeve and the rectangular shell, so that the overall sealing is good, and finally the sliding sleeve is fixedly connected to the rectangular shell by tightening the screws.

[0006] In order to prevent the rubber sleeve from separating from the sliding sleeve when the sliding sleeve is moved, a mounting hole is provided on the rubber sleeve. When the fastening screw is tightened, part of the rubber sleeve is located outside the threaded hole, and the mounting hole is sleeved on the part of the fastening screw located outside the threaded hole.

[0007] The utility model provides a sealing structure for a bus duct connection, which has the beneficial effect that after the exposed conductive copper bars at the ends of the two bus ducts are connected through a connector, the sliding sleeves on the two bus ducts can be slid to align the two sliding sleeves, and then the connecting pieces on the two sliding sleeves are fixedly connected by bolts and nuts, so that the sealing ring is squeezed to seal the connection, and the rubber sleeve ensures the sealing between the sliding sleeve and the rectangular shell, so that the overall sealing is good.
