16.It is jagged inserter between the upper cover plate 14 and lower cover 15 of splicer 11, when copper bar group 5 is connected with splicer 11,
Each copper bar is inserted in 1 sawtooth, and splicer cover plate 10 then inserts the space between upper cover plate 14 or lower cover 15 and sawtooth
In, when the splicer cover plate 10 of insertion props up limiting card 16, represent to be installed in place, splicer lid can be ensured by the setting
Plate 10 is installed in place.
Polyester film 17 is provided with outside each copper bar of the copper bar group 5, is set between copper bar group 5 and upper plate 1 and lower plate 2
There is insulating cell 18.It can ensure that copper bar group 5 has good insulated enclosure performance.
It is described to be each provided with 1 neck 19 in the lower surface of upper plate 1 and/or the head end of the upper surface of lower plate 2 two, also include
The fixed block 20 being placed on upper plate 1 or the end face of lower plate 2, the bottom plate of fixed block 20 are connected with 2 blocks of buckles 21, set on buckle 21
There is the lug boss 22 for being caught in neck 19,2 connecting rods 23 are connected with the backboard of fixed block 20, the other end of connecting rod 23 is worn
It is fixed on after crossing the vertical chute 25 of vertical connecting plates 24 in vertical connecting plates 24, between fixed block 20 and vertical connecting plates 24
Shock-absorbing spring 26 is penetrated on the shaft of connecting rod 23, vertical connecting plates 24 are connected with fixed plate 27.It is provided with fixed plate more than 27
Individual mounting hole.Fixed block 20, buckle 21, connecting rod 23, vertical connecting plates 24, shock-absorbing spring 26 and fixed plate 27 form vibration damping dress
Put.
When the bus duct is installed, fixed plate 27 is fixed on wall after bolt to be passed through to the mounting hole in fixed plate 27,
Then the lug boss 22 of buckle 21 is caught in neck 19, then tightened the bolt between buckle 21 and fixed block 20, you can
Bus duct and fixed block 20 are fixed together, then penetrated vibration damping in connection between fixed block 20 and vertical connecting plates 24
The connecting rod 23 of spring 26,23 two head ends of connecting rod are fixed on fixed block 20 and vertical connecting plates 24 by nut.Pass through
Vibration absorber can fix bus duct, when bus duct front and rear vibration along its length, due to bus duct and fixed block 20
It is fixed together, fixed block 20 is and then vibrated together, and shock-absorbing spring 26 can be compressed in vibration processes, is offset by shock-absorbing spring 26
The vibration of bus duct fore-and-aft direction.When bus duct up-down vibration, bus duct can drive fixed block and connecting rod 23 together along perpendicular
Vibrated to the direction of chute 25, the vibration will not drive fixed plate 27 to vibrate together.Therefore bus duct is when vibrating, will not drive pair
Its fixed plate 27 being fixed is vibrated together, good damping result.
The vertical connecting plates 24 are connected with baffle plate 28, and the spacing between 2 pieces of baffle plates 28 is equal to upper plate 1 or the width of lower plate 2
Degree.The left and right sides of bus duct can be propped up in 2 pieces of installation processes of baffle plate 28, bus duct can be weakened in right and left by baffle plate 28
To vibration.
2 horizontal concrete chutes 29 are each provided with the bottom plate and backboard of the fixed block 20.Horizontal concrete chute 29 on bottom plate is
In order to facilitate installation buckle 21, unscrew the bolt of fixed buckle 21, it is slid in and out along horizontal concrete chute 29, you can by buckle 21
Separated with fixed block 20.And the one of horizontal concrete chute 29 on the backboard of fixed block 20 conveniently adjusts the installation position of connecting rod 23
Put, when the vibration of left and right directions occurs for bus duct, the horizontal concrete chute 29 can also provide one for the vibration of bus duct for the two
Oscillation space, avoid driving fixed plate 27 to vibrate together in vibration processes.
