Description
Technical field
The present invention relates to automobile sensor encapsulating structure, and in particular to a kind of reliable sensor encapsulation knot of sealing property
Structure.
Background technology
The parts of the automobile sensor of cavity, Metal Structural Parts that needs get rusty electronic component and easily during production etc.
It is sealed in the parts cavity inside.At present, automobile sensor present on market, in order to realize an electronic component, hardware
Structural member etc. is sealed in sensor, generally using embeddings such as silica gel, epoxy resin, polyammonium greases.This sensor of in the market
The mode of sealing there is a problem of it is many, such as：Hardening time is long, need quantitative adhesive injection device, need the equipment of being heating and curing, and produces
Cycle is long, input cost is high, efficiency is low.
The content of the invention
In view of the shortcomings of the prior art, the invention discloses a kind of reliable sensor-packaging structure of sealing property.
Technical scheme is as follows：
A kind of reliable sensor-packaging structure of sealing property, including shell；Biography is fixed among the inner chamber of the shell
Sensor electronic component；Also include inner sleeve and the outer tube being socketed on outside the inner sleeve；The sensor electronics
Wire is drawn by the inner tube；The outer tube is connected on the shell；The shell is connected with the outer tube
The end for connecing, is fixed with rubber stopper and becket successively from inside to outside；The rubber stopper and the becket are enclosed within described
Outside sleeve pipe, and it is embedded within the shell；The outer tube space adjacent with the inner sleeve, the shell is molded close
Envelope.
Its further technical scheme is, in the shell and the junction of the outer tube, the connection end of the shell
Portion includes diameter less than the first depressed part of the diameter of the shell and with diameter greater than first depressed part and outer less than described
First lug boss of shell, the connection end of the outer tube includes that inwardly protruded second lug boss and diameter are less than described second
Second depressed part of lug boss；First concave part is mutually chimeric with second lug boss；First lug boss with it is described
Second depressed part is mutually fitted together to.
The method have the benefit that：
Simple structure of the present invention, good seal performance can effectively prevent the corrosion of water or air to sensor electronics
And influence.Manufacture craft of the present invention is simple, when high-volume makes, it is possible to decrease production cost, improve production efficiency.
Brief description of the drawings
Fig. 1 is structure chart of the invention.
Fig. 2 is the enlarged drawing of part A in Fig. 1.
Specific embodiment
Fig. 1 is structure chart of the invention.As shown in figure 1, the present invention includes shell 1, biography is fixed among the inner chamber of shell 1
Sensor electronic component 4.Also include inner sleeve 6 and the outer tube 7 being socketed on outside inner sleeve 6.The wire of sensor electronics 4
Drawn by inner tube 6.Outer tube 7 is connected on shell 1.The end that shell 1 is connected with outer tube 7, from inside to outside successively
Rubber stopper 2 and becket 3 are fixed with, rubber stopper 2 and becket 3 are enclosed within outside inner sleeve 6, and are embedded within shell 1.Overcoat
The space adjacent with inner sleeve 6, shell 1 of pipe 7 is molded sealing.
By the present invention in that compressing rubber stopper 2 with becket 3, sensor electronics 4 etc. are sealed in the inner chamber of shell 1
Among, closing is then molded again outside rubber stopper 2 and the end face of becket 3, so as to reach the effect for preventing water from entering with gas.
Fig. 2 is the enlarged drawing of part A in Fig. 1.Preferably, shell 1 and outer tube 7 can be used method phase as shown in Figure 2
Connection, to increase the fastness of connection, further increases sealing property.
Referring to Fig. 2, in shell 1 and the junction of outer tube 7, the connection end of shell 1, from the inside to the outside, including diameter is small
In the first depressed part 11 of the diameter of shell 1 and with diameter greater than the first depressed part 11 and less than the first lug boss 12 of shell 1.Outward
The connection end of sleeve pipe 7, from outside to inside, including inwardly protruded second lug boss 71 and diameter are less than the of the second lug boss 71
Two depressed parts 71.Then when shell 1 is connected with outer tube 7, the first concave part 11 is mutually chimeric with the second lug boss 71；First is convex
Play portion 12 mutually chimeric with the second depressed part 71, degree of being connected firmly can be increased.
Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above example.It is appreciated that this
Other improvement and change that art personnel directly derive or associate without departing from the spirit and concept in the present invention
Change, be considered as being included within protection scope of the present invention.
