Abstract
The utility model discloses a bus duct expansion joint, comprising a housing and wire rows on left and right sides of the housing. Separation insulation filler strips are arranged among the wire rows, wherein the separation insulation filler strips are closely laminated with the wire rows. Left and right ends of the housing narrow down to form connecting ends. The wire rows extend into the housing from the connecting ends. The parts of the wire rows extending into the housing are used as conductive ends; the conductive ends bend upwards and downwards; conductive leather flexible coupling pieces capable of bending are connected among the conductive ends; insulation separation films are arranged among the conductive ends, wherein gaps are left between the insulation separation films and the conductive leather flexible coupling pieces. The expansion joint realizes an adjusting function through the conductive leather flexible coupling pieces of a total bus duct box housing in a mobile housing, realizes electrical connection through connection between the conductive leather flexible coupling pieces and the conductive ends, and raises security through the movement of the conductive leather flexible coupling pieces which compensates for errors caused by thermal expansion and contraction.
Description
Technical field
The utility model relates to bus duct field, particularly a kind of for tackling the expand with heat and contract with cold expansion joint of phenomenon of bus duct.
Background technology
In project of transmitting and converting electricity, bus duct can carry carries large electric current.And bus duct is worked for a long time in complex environment, can run into and in longer straight-line bus duct system, expand with heat and contract with cold and the problem of alignment error, this is for being very dangerous at the bus duct of high-power energising for a long time.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of structure simpler, safe bus duct expansion joint.
The utility model solves the technical scheme that its technical problem adopts:
A kind of expansion joint of bus duct, comprise housing and be positioned at a housing left side, the line row of right both sides, between each line row, be provided with and separate insulation filler strip, wherein separation insulation filler strip and line row are close to installation, a left side for described housing, formation link is narrowed at right two ends, described line row stretches in housing from link, described line is arranged the part that stretches into housing as conducting end, wherein said conducting end upwards, lower direction bending, between described conducting end, be connected with the soft and soggy connection of flexible conduction, between described each conducting end, be provided with insulation separation membrane, wherein said insulation separation membrane and conduction leave space between soft and soggy connection.
As a preference, described conducting end and the stacked installation between soft and soggy connection of conducting electricity, and be bolted.
As a preference, the left and right, position of the bolt junction of the conducting end of described each layer and the soft and soggy connection of conduction is in staggered distribution.
As a preference, the skin of the soft and soggy connection of described conduction and conducting end contact portion is coated with silver coating.
The beneficial effects of the utility model are: the conduction soft and soggy connection of the housing of this expansion joint by common box bus in movable housing realizes regulatory function, is connected to realize and is electrically connected by conducting electricity soft and soggy connection and line row's conducting end, by conduct electricity soft and soggy connection activity make up expand with heat and contract with cold produce error, improved fail safe.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is front view of the present utility model.
embodiment
With reference to Fig. 1, an expansion joint for bus duct, comprises housing 1 and the line row 2 who is positioned at housing 1 arranged on left and right sides, between each line row 2, is provided with and separates insulation filler strip 3, wherein separate insulation filler strip 3 and be close to installation with line row 2, separate insulation filler strip 3 and adopt the manufacture of insulation heat-barrier material.The left and right two ends of described housing 1 are narrowed and are formed link 11, described line row 2 stretches in housing 1 from link 11, described line row 2 parts that stretch into housing 1 are as conducting end 21, the direction bending up and down of wherein said conducting end 21, between described conducting end 21, be connected with the soft and soggy connection 4 of flexible conduction, the soft and soggy connection 4 of wherein conducting electricity is coated with copper or aluminium skin outward.Between described each conducting end 21, be provided with insulation separation membrane 5, wherein said insulation separation membrane 5 soft and soggyly leaves space between being connected 4 with conducting electricity.
Described conducting end 21 and the stacked installation between soft and soggy connection 4 of conducting electricity, and connect convenient installation by bolt 6.The left and right, position of the bolt junction of the conducting end 21 of described each layer and the soft and soggy connection 4 of conduction is in staggered distribution, and has further improved installation effectiveness.
The soft and soggy connection of described conduction 4 is coated with silver coating with the skin of conducting end 21 contact portions, ensures junction between the soft and soggy connection 4 of conduction and conducting end 21 not and is soft and soggyly connected 4 deformation and affects conductivity because conduct electricity.
Through facts have proved, in the time of real work, in the time that the line row 2 of bus duct occurs deformation because of expanding with heat and contract with cold, line row 2 conducting end 21 can change, and the soft and soggy connection 4 of conducting electricity is also tightened up thereupon or stretches, and ensures that line row 2 connects normally.
According to above-mentioned principle, the utility model can also carry out suitable change and amendment to above-mentioned execution mode.Therefore, the utility model is not limited to embodiment disclosed and described above, also should fall in the protection range of claim of the present utility model modifications and changes more of the present utility model.
