Specific implementation mode
With reference to the accompanying drawings and examples, the utility model is described in detail.
A kind of isolation electrical interference device, including：Two connectors, connect cover and insulating washer.Two connectors pass through company
It connects cover to be fixedly connected, connect cover is sleeved on the outer circumference surface of two connectors；Between two connectors and connector and company
It connects and is isolated by insulating washer between cover, the insulating washer between two connectors, two connectors is collectively formed for transmitting
The access of pressure.
As shown in Figure 1, for the isolation electrical interference apparatus structure sectional view of the utility model, which includes
Two connectors, two connect covers and insulating washer, two connectors are respectively：Connector I 1 and connector II 7, two connections
Cover is respectively：Connect cover I 3 and connect cover II 6, insulating washer are respectively：Step felt pad I 2, barrel type insulation pad I 4, step are exhausted
Edge pad II 8, barrel type insulation pad II 9 and insulation spacer 5.
Connector I 1 and connector II 7 are that there are one the cylinder of step end face, cylinder inner hollow, logical high pressures for tool
Gas for transmitting pressure, but wherein by be not limited to high pressure gas.
Connect cover I 3 and connect cover II 6 are the cover body structure of end face trepanning.
Connect cover I 3 is sleeved on the outer circumference surface of connector I 1, the platform of the inner surface and connector I 1 of I 3 end cap of connect cover
Rank end face fastens, and connect cover II 6 is sleeved on the outer circumference surface of connector II 7, the inner surface of II 6 end cap of connect cover and connection
The step end face of part II 7 fastens, and connect cover I 3 and connect cover II 6 pass through the step end face on connector I 1 and connector II 7
The axial displacement of itself is limited, meanwhile, connect cover I 3 is threadedly coupled with connect cover II 6 by connector I 1 and the fixation of connector II 7
Connection.
It is isolated by insulation spacer 5 between connector I 1 and the step end face of connector II 7, connector I 1, connector II 7
And the access for transmitting pressure is collectively formed in insulation spacer 5.The step of the inner surface and connector I 1 of I 3 end cap of connect cover
The position that end face fastens is isolated by step felt pad I 2, and step felt pad I 2 is sleeved on I 1 outer circumference surface of connector；Even
It connects and is isolated by barrel type insulation pad I 4 between the side wall inner surfaces of I 3 lid of cover and the step outer circumference surface of connector I 1, tubular is exhausted
Edge pad I 4 is sleeved on I 1 step outer circumference surface of connector.
The position that the inner surface of II 6 end cap of connect cover and the step end face of connector II 7 fasten passes through step felt pad
II 8 isolation, step felt pad II 8 are sleeved on II 7 outer circumference surface of connector；The side wall inner surfaces of II 6 lid of connect cover and company
It is isolated by barrel type insulation pad II 9 between the step outer circumference surface of fitting II 7, barrel type insulation pad II 9 is sleeved on connector II 7
On rank outer circumference surface.
Polytetrafluoroethylene (PTFE) is a kind of material with antiacid alkali, anti-various organic solvents, has good insulating properties.This is special
Point can ensure that the device repeatedly uses.Therefore, the insulating washer of the utility model uses polytetrafluoroethylene (PTFE).
The connection of connector I 1 is measured device, i.e., extra interference electric signal generates end, is set as the ends A, the connection pressure of connector II 7
Force snesor is set as the ends B, i.e. pressure signal collection terminal, since the ends A have extra interference electric signal, so as to cause pressure sensing
