Enclosed busbar reduces volume, saves space, but the conductor of laminated structure is easily-deformable.
Utility model content
It is opposite to be closed from case purpose of the utility model is to solve the above problems and provide a kind of case enclosed busbar altogether
Bus is small in size, saves space.
To solve the above-mentioned problems, the technical solution adopted in the utility model is as follows:
Case enclosed busbar altogether, the bus-bars conductor including square casing and enclosure interior, the bus-bars conductor are strip gold
Belong to plate, multiple metal plates form single group bus-bars conductor side by side, and multiple groups bus-bars conductor is spaced apart to be arranged side by side, each group bus
Conductor bottom is equipped with multiple insulator support columns, and each insulator support column is spaced apart to be distributed along bus-bars conductor, insulation
Son support column bottom is fixedly connected with housing bottom, and each metal plate top, bottom are respectively equipped with positioning plate in single group bus-bars conductor,
Each metal plate is set in positioning plate groove, and insulation column is equipped between top, bottom spacer, and insulation column top, bottom are set
There is threaded hole, positioning plate is bolted to connection with insulation column.
Be optimized for, bus-bars conductor end, which is equipped with, expands with heat and contract with cold buffer part, buffer part of expanding with heat and contract with cold be superimposed by multilayer aluminium sheet and
At buffer part of expanding with heat and contract with cold is in bending waveform.
The utility model has the beneficial effects that
The utility model can determine the metal plate the piece number in single group bus-bars conductor for current flow, and the magnitude of current is bigger,
Metal plate the piece number is more；
Positioning plate plays positioning, isolation, supporting role to the metal plate in single group bus-bars conductor, avoids bus-bars conductor change
Shape；
The positioning plate and insulator support column of bus-bars conductor bottom play a supporting role to bus-bars conductor, and mother of having insulated
Line conductor and shell；
Bus-bars conductor is metal plate side by side, relative to tubular from case bus-bars conductor, small in size, space occupied
It is small.

Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
It participates in shown in Figure of description 1, altogether case enclosed busbar, including square casing 1 and the bus-bars conductor of enclosure interior 2,
The bus-bars conductor is elongated metal plate, and multiple metal plates form single group bus-bars conductor, multiple groups bus-bars conductor interval one side by side
Set a distance is arranged side by side, and the metal plate the piece number in single group bus-bars conductor can be determined for current flow, the magnitude of current is bigger, metal
Plate number is more.
Each group bus-bars conductor bottom be equipped with multiple insulator support columns 3, each insulator support column 3 it is spaced apart along
Bus-bars conductor distribution, 3 bottom of insulator support column is fixedly connected with 1 bottom of shell, each metal plate top in single group bus-bars conductor,
Bottom is respectively equipped with positioning plate 41, and each metal plate is set in positioning plate groove, and insulation column is equipped between top, bottom spacer
42,42 top of insulation column, bottom are equipped with threaded hole, and positioning plate 41 is fixedly connected with insulation column 42 by bolt 43.Positioning
Plate plays positioning, buffer action to the metal plate in single group bus-bars conductor；The positioning plate and insulator of bus-bars conductor bottom support
Column plays a supporting role to bus-bars conductor, and insulated bus-bars conductor and shell.
Bus-bars conductor will appear during the energization to expand with heat and contract with cold, if bus-bars conductor external connection electric equipment, bus are led
2 end of body is equipped with buffer part 21 of expanding with heat and contract with cold, and buffer part of expanding with heat and contract with cold 21 is formed by stacking by multilayer aluminium sheet, buffer part of expanding with heat and contract with cold
