Bus duct joint connecting structure

Abstract

The invention discloses a bus duct joint connecting structure. The bus duct joint connecting structure comprises bus ducts and a plug-in structure, U-shaped conductors are arranged in the two sections of the bus ducts, the plug-in structure comprises an insulating support and a plug-in conductor; the bottom portion of the insulating support is provided with a bottom plate, a top plate and side plates, two side surfaces of the plug-in conductor are provided with watchband contact fingers, and the plug-in conductor can be inserted into inner cavities of corresponding U-shaped conductors in the two sections of the bus ducts and enables the watchband contact fingers to be in compression contact with the U-shaped conductors. By adopting foretell structure, the plug-in structure is reasonable in design, convenient to install, stable and reliable in plug-in, very good in sealing and high in safety, does not need an insulation separator, is good in heat radiation, greatly enlarges the application range; and moreover, the watchband contact fingers make conductive contact stable and reliable, the conductivity is very good, the hunch structure of watchband contact fingers is adopted to achieve the tight connection of plug and conductor, and the connection strength is very high and durable.

Description

technical field [0001] The invention relates to a component for power transmission and distribution in a power supply system, in particular to a connection structure of a bus duct joint. Background technique [0002] Various bus ducts are often used in power transmission and distribution in the power supply system. The existing bus ducts generally include the shell and the multi-phase conductors covered by insulating materials in the shell. When the bus duct When the length is long, it is usually necessary to butt the busway. The existing busway is usually connected with auxiliary conductors for auxiliary installation, and at the same time, it needs to be separated by insulating partitions. There is no guarantee, so problems such as poor contact often occur. In addition, the sealing of the butt joint is poor, which is not conducive to waterproofing and reduces safety. Contents of the invention [0003] The technical problem to be solved by the present invention is to prov...
