Degree, so that the short axle side of oval or diamond shaped insulation tube card slot insertion resistance band or resistor disc ellipse or diamond hole forms buckle
Structure.
8. improving the method for plate resistor unit insulation performance as claimed in claim 6, it is characterised in that: described to whole
It is that fixed device is arranged in the end of whole insulation tube that insulation tube, which is fixed, by fixed device by whole insulation tube and entirely
Other components of resistance unit are connected and fixed, and formation is bonded.
9. improving the method for plate resistor unit insulation performance as claimed in claim 2, it is characterised in that: described will own
It is to output semicircular open in the upper and lower side of resistance band or resistor disc that resistance band or resistor disc, which are caught in the card slot of whole insulation tube,
Mouthful, whole insulation tube is also made into round shape or multiple tooth shape, and be provided with card slot on the outer surface of round shape or multiple tooth shape insulation tube, often
The corresponding resistance band of one card slot or resistor disc；Resistance band or resistor disc continuous arrangement are got up, then by whole round shape or multiple tooth
Shape insulation tube corresponds to a resistance band or resistance from the semicircular opening of resistance band or the upper and lower side of resistor disc with each card slot
Piece, by the semicircular opening of the whole eradication edge pipe clamp upper and lower side that enters resistance band or resistor disc, so that resistance band or resistor disc
Port forms fixation, and by whole insulation tube to carrying out isolated insulation between resistance band or resistor disc；In whole eradication edge pipe clamp
Whole insulation tube is fixed again after entering resistance band or resistor disc component, forms resistance band or resistance blade unit.
10. improving the method for plate resistor unit insulation performance as claimed in claim 9, it is characterised in that: described whole
Thoroughly doing away with edge pipe clamp and enter and whole insulation tube being fixed again after resistance band or resistor disc component is that supporting element is inserted into whole eradication edge
In the centre bore of pipe, then whole insulation tube for being inserted with supporting element be caught in resistance band outside the upper and lower ends of resistance band or resistor disc
Or in the semicircular opening of resistor disc upper and lower side, so that every Single port all snaps onto the card slot of whole insulation tube to resistor disc up and down
It is interior, it is then again that whole insulation tube is relatively fixed together with supporting element, form complete resistance unit.
