Abstract
The utility model discloses a leading wire sealing device, comprising a housing. The housing is provided with a step hole which becomes smaller from top to down; a leading wire body is arranged in the step hole; the internal part of the leading wire body forms a cylindrical cavity; the bottom of the cavity is provided with a plurality of wire apertures, through which leading wires penetrate. The inner of the cavity is poured with vacuum seal resin; an central section outside of the leading wire body forms a circular boss; a seal ring is arranged between a lower end of the boss and a large hole bottom of the step hole; the leading wire body is fixed in the step hole through screws and a flange; the seal ring is pressed. The lead wire sealing device has a simple structure, is convenient to install and has good sealing effects.
Description
Technical field
The utility model belongs to a kind of packoff, is specifically related to a kind of lead sealing equipment that can be used for vacuum or the sensor in the environment of gas differential pressure is arranged.
Background technology
In various field tests, the application of sensor is very extensive.Generally speaking, sensor all is that information measured is converted into electrical quantity, processes through transducer and amplifies, and offers data acquisition process equipment, so, all there is wire to connect between sensor and the transducer.At some in particular cases, be operated in vacuum or have in the environment of gas differential pressure such as testee, the lead-in wire of sensor just needs encapsulation process, is in the sealed environment to guarantee testee.
Disposal route commonly used in the prior art is: use and be with foraminate sealing rubber pad, sensor conductor is passed from aperture, rubber blanket is put into the seal bore of housing, then use flange screw, realize sealing.The shortcoming of this kind method is easily wire to be broken or damages by pressure wire insulation, causes opening circuit or the situation of short circuit occurs, and affects normal operation of sensor; If wire is too much, then the contact area of flange and rubber blanket can reduce, and causes wire sealing gasket on every side to compress, and makes the sealing effectiveness variation.
Summary of the invention
The utility model provides in order to overcome the shortcoming that exists in the prior art, and its objective is provides a kind of simple and reliable, the lead sealing equipment of good sealing effect.
The technical solution of the utility model is: a kind of lead sealing equipment, comprise housing, and form up big and down small shoulder hole at housing, in shoulder hole, be provided with the lead-in wire body, lead-in wire body inside is formed with cylindrical cavity, and cavity bottom has a plurality of lines hole.Lead-in wire is penetrated by the line hole, cast vacuum seal resin in the cavity,, the outside, lead-in wire body middle part is formed with round boss, O-ring seal is installed between bottom the macropore of boss lower end and shoulder hole, be fixed in the shoulder hole with screw and the flange body that will go between, and the press seal circle.
Periphery at described shoulder hole forms uniform a plurality of screws.
In described flange, be formed centrally through hole, form uniform a plurality of unthreaded holes in the periphery of through hole.
Lead-in wire sealing of the present utility model is finished by sealing resin, and behind the resin solidification of cast, the body that will go between and go between bonds together, and has avoided the squeezing action to lead-in wire, and the sealing of lead-in wire body realizes by sealing rubber ring.So the utility model is simple in structure, easy for installation, good sealing effect.
Description of drawings
Fig. 1 is lead sealing equipment structural representation of the present utility model.
Wherein:
1 housing, 2 shoulder holes
3 screws, 4 lead-in wire bodies
5 lead-in wires, 6 resins
7 screws, 8 flanges
9 O-ring seals, 10 boss.
Embodiment
Below, in conjunction with the accompanying drawings and embodiments lead sealing equipment of the present utility model is elaborated:
As shown in Figure 1, a kind of lead sealing equipment comprises housing 1, forms up big and down small shoulder hole 2 on the housing 1, forms uniform a plurality of screws 3 along the periphery of shoulder hole 2.Be provided with lead-in wire body 4 in shoulder hole 2, lead-in wire body 4 inside are formed with cylindrical cavity, and cavity bottom has a plurality of lines hole, and the present embodiment is 2, lead-in wire 5 is penetrated by the line hole, is positioned at cylindrical cavity, casting resin 6 in the cavity, behind the resin solidification, will go between 2 fixing, and play sealing function.The outside, lead-in wire body 4 middle parts is formed with round boss 10, between the macropore bottom of boss 10 lower ends and shoulder hole 2 O-ring seal 9 is installed.
Flange 8 central authorities are formed with the boss with through hole.
The periphery of flange 8 through holes forms uniform a plurality of unthreaded holes, and the number of unthreaded hole and position are corresponding with number and the position of screw 3.
Be fixed in the shoulder hole 2 with screw 7 and flange 8 body 4 that will go between, and press seal circle 9, the inner chamber that makes housing 1 keeps sealing with extraneous.
The utility model is simple in structure, easy for installation, good sealing effect.
