Piece outmost turns set thickening layer, can cause that aluminium base sheet material and the direct cushion space of pilot pin are bigger in use, most
Avoiding direct contact with for limits causes to scratch.
Further, the pad is made up of elastomeric material.Pad is made with elastomeric material, its resiliency can be strengthened
Energy.
Further, the diameter with diameter greater than block of the pad.It is more than block by set the diameter of pad
Diameter, more preferable buffering effect can be played.
Further, the aluminium base sheet material is made up of copper foil layer, insulating barrier and aluminium base from top to bottom, the copper foil layer
Thickness is 0.02-0.05mm, and the thickness of insulating barrier is 0.1mm, and the thickness of aluminium base is 1.2-1.5mm.
Further, the thickness of the copper foil layer is 0.03mm, and the thickness of the aluminium base is 1.38mm.
Further, the thickness of the aluminium base sheet material is 1.6mm.
The present invention compared with prior art, has the advantages that：
The present invention leaks the quality problems such as copper by setting baffle plate to prevent scuffing of the profiled sheeting caused by pilot pin.Because fixed
The quality problems such as position pin is scratched, leakage copper improve improving productivity quality again without generation.Simultaneously in block and aluminium base sheet material diameter
Pad is set, block can be further placed and be contacted with the direct of aluminium base sheet material, the table for preferably preventing from scratching aluminium base sheet material
Face, it is ensured that the qualification rate of product.
