Guarantee that the card slot of integral insulation pipe can be caught in the upper and lower side of resistance band or resistor disc, and there can be no the card slots of integral insulation pipe
Bottom and half-open port recess generate interference.
8. the isolated insulation method for entering resistor disc by integral insulation pipe clamp as described in right wants 6, it is characterised in that: described
The opening direction of semi-open slot is identical for the opening of resistance band or the semi-open slot of the upper and lower side of resistor disc, or opposite, or mutually
At plumbness.
9. a kind of realize the resistance unit for entering the isolated insulation method of resistor disc described in claim 1 by integral insulation pipe clamp,
Including the insulating part and support rod between resistance band or resistor disc, resistance band or resistor disc, by support rod, resistance band or resistor disc
Between insulating part and resistance band or resistor disc combine to form resistance unit；Centre bore is equipped on insulating part, support rod passes through
Resistance band or resistor disc are isolated and are positioned between each other by the centre bore on insulating part；It is characterized in that, the insulating part is
Integral insulation pipe；Semi-open slot is equipped at resistance band or resistor disc both ends, and integral insulation pipe is from resistance band or resistor disc both ends
It is caught in resistance band or resistor disc equipped with semi-open slot, is formed and forms isolation and positioning between resistance band or resistor disc.
10. resistance unit as claimed in claim 9, it is characterised in that: the integral insulation pipe is from resistance band or resistor disc
Both ends are caught in resistance band equipped with semi-open slot or resistor disc is that supporting element is inserted into the centre bore of integral insulation pipe, then will be inserted with
The integral insulation pipe of supporting element is caught in the semicircle of resistance band or resistor disc upper and lower side outside the upper and lower ends of resistance band or resistor disc
In shape opening, so that every Single port all snaps onto the card slot of integral insulation pipe resistor disc up and down, then again by integral insulation pipe
It is relatively fixed together with supporting element, form complete resistance unit.
