It is trapezoidal.
Cushion block has the opening docked with pressing plate body notch, and cushion block is stepped in thickness direction, is installed on pressing plate sheet
Body bottom.
The notch is U-shaped mouth, and cushion block is arranged on the side portion of U-shaped mouth two by cardboard pin.
A kind of transformer pressing plate of the present invention and the outlet method of outlet fit structure, comprise the following steps：
Pressing plate body is separated in a manner of drawer with cushion block, pressing plate exposes open notch；
Lift one's head each layer square ring and insulating part are installed at notch；
Lift one's head after each layer square ring and insulating part installation, cushion block insertion notch is installed, and use cardboard pin
It is fixed；
By oil seal plate in pressing plate bottom correspondence position, installation fixation is carried out using insulation blanket stud and nut, overall structure is complete
Into.
The inventive method is further comprising the steps of：
Slotted in pressing plate body side, cushion block combination pressing plate body fluting size carries out matched design；
Pressing plate body notch edge reserving installation hole.
Prepared before oil seal plate installation by the outer limit size for molding part of lifting one's head.
The invention has the advantages that and advantage：
1. the positional structure that coordinates with outlet lower platen of the present invention is adjusted, by pressing plate perforate epitaxial part with
The mode of " drawer " separates, ensure design theory installation dimension requirement on the premise of, also ensure lift one's head installation square ring and absolutely
The operating space of edge part, while convenient operate, it ensure that the radiating efficiency of the forced-directed oil structure of product.
2. simple and ingenious structure of the present invention, swift to operate, man-hour is saved, reduces cost of labor.
