Herein, " schematic " expression " serving as example, example or explanation " should not will be described herein as " showing Any diagram, the embodiment of meaning property " are construed to a kind of preferred or more advantageous technical solution.
As shown in Figure 1, the present invention provides detachable flexible contact measuring instrumentss, equipment under test shell 90 and tested table Connected between face 91 by Measurement channel 92, the contact measuring instrumentss include gland 10, sensor 20, spring 30, baffle ring 40, Conducting wire 50, gripping sleeve 60 and pressure cap 70.
Gland 10, which has, penetrates through the reducing hole of itself, and reducing hole communicates with Measurement channel 92,10 bottom of gland be fixed on by 90 outside of measurement equipment shell.In the present embodiment, gland 10 is fixed by fastener and 90 phase of equipment under test.
20 both ends of sensor are respectively measurement end and connecting pin, and measurement end is through equipment under test shell 90 and logical positioned at measurement In road 92, DATA REASONING is carried out, connecting pin is located in the reducing hole of gland 10, has at the close measurement end of 20 outer wall of sensor Collar 21.In the present embodiment, tool is there are two collar 21 at the close measurement end on 20 outer wall of sensor, shape between two collars 21 Into groove in equipped with cushion rubber 80, cushion rubber 80 and the extruding of 92 phase of Measurement channel, for sealing.
Spring 30 is socketed on 20 outside of sensor, and one end squeezes collar 21 and sensor 20 is made to be pressed in measured surface 91, The other end squeezes 10 bottom end face of gland.
Baffle ring 40 is located in the reducing hole of gland 10 and is installed at the close connecting pin of sensor 20, on the radial Keep position of the sensor 20 in gland 10.In the present embodiment, a baffle ring is provided at the close connecting pin of 20 outer wall of sensor Groove, baffle ring 40 are fixed in baffle ring groove, and 40 outside of baffle ring and the inner wall in 10 reducing hole of gland have gap.
50 one end of conducting wire is located in gland 10 and is connected with connecting pin, and the other end is pierced by from gland 10, is used for transmission feedback Signal.In the present embodiment, unrestrained pipe 61 is socketed on conducting wire 50, the position of unrestrained pipe 61 is engaged with the closing-in structure of gripping sleeve 60.
Gripping sleeve 60 is fixed on by pressure cap 70 in the reducing hole of gland 10, and gripping sleeve 60 has closing-in structure.
Pressure cap 70 is bolted in 10 top of gland, and 70 top of pressure cap has and the matched taper of closing-in structure of gripping sleeve 60 Structure compresses closing-in structure by pyramidal structure, and then unrestrained pipe 61 is made to clamp conducting wire 50.
The operation principle of the present invention is as follows:
As shown in Figure 1, when instrument is in disassembled state, gland 10 is not fixed on equipment under test shell 90 at this time, pressure Cap 70 is also at releasing orientation, and conducting wire 50 is from the clamping force of gripping sleeve 60, i.e., conducting wire 50 can be freely movable, while baffle ring 40 The left end of gland 10 can be stuck in, prevents gland 10 from scraping conducting wire 50, while is also prevented from 50 stress of conducting wire.
When installing instrument, confirmation pressure cap 70 is releasing orientation, ensures that conducting wire 50 can be freely movable, gland 10 is aligned survey Measure passage 92 with being screw fastening on equipment under test shell 90, tighten pressure cap 70, at this time gripping sleeve 60 be subject to pressure cap 70 squeeze and Tightening, and then unrestrained pipe 61 is made to compress conducting wire 50, conducting wire 50 can be fixed, prevent solder joint stress, and can grease-proof and waterproof.Instrument After table installs, sensor 20 is stretched into Measurement channel 92, and is subject to the elastic force of spring 30 and is withstood measured surface 91 into line number According to measurement.
When dismantling instrument, pressure cap 70 is first unclamped, unclamps again the screw of stationary gland 10, and hand-held gland 10 pulls out instrument.
The above description is merely a specific embodiment, but protection scope of the present invention is not limited thereto, any Those familiar with the art in the technical scope disclosed by the present invention, all should by the change or replacement that can be readily occurred in It is included within the scope of the present invention.Therefore, protection scope of the present invention should using the scope of the claims as It is accurate.
