8 center of connection sheet has through-hole, and 3 side of insulating barrier closely mounts conductor tab 8, and adjacent two pieces of insulating barriers 3 do not mount
By limited step held tight cooling fin 9 between the side of conductor tab 8, adjacent two pieces of insulating barriers 3 closely lead by attachment
The conductive trough being inserted into for bus duct product phase conductor 10 is formed between the side of body connection sheet 8, is provided among insulating barrier 3
Limited block causes conductive trough accurate positioning, and bus duct phase conductor can easily be smoothly inserted into conductive trough when scene pacifies half, installs
It is convenient；Track bolt 6 fastens after passing through insulating barrier 3,8 central through hole of conductor tab with the mating connection of collar nut 5, connector
Insulation sleeve 7,6 end of track bolt, collar nut 5 are provided between bolt 6 and insulating barrier 3,8 central through hole of conductor tab
It is provided with butterfly spring piece 4 and connector pressing plate 2 between outermost layer insulating barrier 3, connector pressing plate 2 is cut by pultrusion
The section bar of the approximately c-shaped structure in face is formed, and the through-hole passed through for track bolt 6 is provided among C-shaped configuration, and both sides have outside
Linearly extended wing side；Wing side sets promising bus duct product side plate connector 1 to provide the limiting slot limited；C-shaped configuration inner cavity
Height dimension is adapted with 4 height dimension of splicer disc spring film, and disc spring film 4 can be installed in intracavitary in C-shaped configuration
Portion；C-shaped configuration opening width dimensions are adapted with 5 width dimensions of collar nut；2 material of connector pressing plate is aluminium alloy；Absolutely
Edge set 7 is columnar structured, and 7 both ends of insulation sleeve are against on 4 inner surface of dish-shaped shrapnel of splicer both sides；The connector pressure of splicer
Plate is made of the section bar of the approximately c-shaped structure in the section of a pultrusion, and both sides have outside linearly extended wing side, C-shaped
Structure inner chamber height dimension is adapted with splicer disc spring film height dimension, and disc spring film can be installed in C-shaped configuration
Inner cavity, C-shaped configuration opening width dimensions are adapted with collar nut width dimensions.
Connector pressing plate 2 is made of the section bar of pultrusion of pultrusion production line, the approximately c-shaped structure in section bar section, is drawn
Extrusion section bar may make up product, simple production process by cut-out；It is provided among the C-shaped configuration of section bar section and is worn for track bolt
The through-hole crossed, both sides have outside linearly extended wing side, and wing side sets the side plate connector 1 of promising bus duct product to provide limit
The limiting slot of position, limiting slot inner side edge are bevel edge, and outer side edges are vertical with wing side surface, and splicer connects when being installed with bus duct product
The limiting slot of head pressing plate 2 provides guiding and limiting for the side plate connector 1 of bus duct, and the inside bevel edge of limiting slot causes bus duct
Side plate connector 1 can be easily smoothly inserted between splicer insulating barrier 3 and connector pressing plate 2；Splicer and bus duct
