Description

Bus duct connector

Technical Field

Background

Modern high-rise buildings and large workshops require large amounts of electrical energy, while the large currents of hundreds of amperes required to face such large loads require the use of safe and reliable conductive equipment. The bus duct is a power distribution device for efficiently conveying current, and is especially suitable for the requirements of economic and reasonable wiring of increasingly high buildings and large-scale factories; and the bus duct connector plays an important role as an indispensable component in the installation. The traditional bus duct connector comprises a pair of insulating clamping plates, a plurality of insulating partition plates are arranged between the pair of insulating clamping plates, and a bolt and nut fixing device penetrates through the insulating partition plates and the pair of insulating clamping plates to connect the insulating clamping plates and the insulating partition plates together; the insulating clamping plates are respectively provided with a conductive copper sheet at one side close to the insulating partition plates and at two sides of each insulating partition plate, and an insulating cylinder is arranged between the conductive copper sheets and the bolts for insulating the conductive copper sheets and the bolts; the bolt and nut fixing device comprises a bolt and a nut matched with the bolt; the bolt is a common bolt, namely a single-head bolt.

The bus duct connector with the publication number of CN106711889A comprises a connector body, wherein special-shaped square nuts are arranged on two sides of the connector body, split special-shaped profiles are arranged on two sides of the connector body, each split special-shaped profile comprises a base for sealing the connector body and a small profile for locking the special-shaped square nuts, and the base and the small profile are clamped; the longitudinal length of the small section bar is smaller than the longitudinal length of the base and is not smaller than the width of the special-shaped square nut, although the bus duct connector of the CN106711889A can consume less aluminum alloy of the split type special section bar under the condition of unchanged performance, and the effects of energy conservation and consumption reduction can be achieved.

However, the bus duct connector of CN106711889a described above has the same drawbacks as the conventional bus duct connector: only use single bolt to fix, because single bolt runs through the insulating barrier setting along two insulating splint central axis directions for when two adjacent insulating splint carry out the centre gripping to bus bar in the bus duct, the insulating interior baffle part of keeping away from connecting bolt supports tight effect poor to the centre gripping of bus bar, thereby makes insulating barrier easy with single bolt rotation and slope. In view of this, we propose a busway connector.
