Abstract
The utility model proposes a kind of sealing structures of pressure sensor, shell including sensor, and the terminal that lower end insertion housing tip is open and is coupled, sensing element is installed in the shell, O-ring seal is equipped between the sensing element lower end and shell, the housing tip opening inner wall is equipped with a circle step structure, the terminal lower end is on step structure and the thickness of terminal lower end is greater than the width of step structure, guarantee that terminal lower end a part is in above step structure, another part is in above sensing element and compresses sensing element.The interior design of this structure housing has step, it can guarantee that shell O-ring seal when pressing is compressed in the reasonable scope, it is limited simultaneously by casing step and guarantees that sensing element will not be subject to crushing, cancel the pressure ring on original pressure sensor, the production efficiency of sensor can be effectively improved, the volume that sensor can be reduced simultaneously, reduces the cost of sensor.
Description
Technical field
The utility model relates to a kind of sealing structures of pressure sensor.
Background technique
Come currently, the sealing means used on pressure sensor mainly use pressure ring and shell to be interference fitted compresses seal
Guarantee the sealing of interiors of products.The volume that such sealing means causes stress sensor is larger, higher cost, in pressure sensor
Under volume is smaller and smaller and the light-weighted requirement of vehicle, competitiveness is lost.
Utility model content
The utility model proposes a kind of sealing structure of pressure sensor, structure is simple, assembly is simple, product uses the longevity
Life is long and functional reliability is high, and terminal directly presses sensing element, eliminates pressure ring, the inside that can effectively reduce sensor is empty
Between, mitigate the weight of sensor.
The technical solution of the utility model is achieved in that
A kind of sealing structure of pressure sensor, shell 1 and lower end insertion housing tip opening including sensor
And the terminal 5 being coupled, sensing element 3 is installed in the shell 1, is set between 3 lower end of sensing element and shell
There is O-ring seal 2, the 1 top end opening inner wall of shell is equipped with a circle step structure, and 5 lower end of terminal is in step structure
Upper and terminal lower end thickness is greater than the width of step structure, guarantees that 5 lower end a part of terminal is in above step structure, another
It is partially in 3 top of sensing element and compresses sensing element 3.
Preferably, described to be designed by decrement needed for the thickness of sensing element 3, the specification of O-ring seal 2 and sealing
The height of enclosure interior step guarantees that the O-ring seal 2 when pressing of shell 1 is compressed in the reasonable scope, while passing through shell platform
Rank limit guarantees that sensing element will not be subject to crushing.
The utility model is the beneficial effects are as follows: enclosure interior design has step, it is ensured that shell is O-shaped when pressing
Sealing ring compresses in the reasonable scope, while being limited by casing step and guaranteeing that sensing element will not be subject to crushing, and cancels original pressure
Pressure ring on force snesor can effectively improve the production efficiency of sensor, while can reduce the volume of sensor, reduce sensor
Cost.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the step structure schematic diagram of shell.
Specific embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with the utility model embodiment,
Obviously, the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.It is practical based on this
Embodiment in novel, every other reality obtained by those of ordinary skill in the art without making creative efforts
Example is applied, is fallen within the protection scope of the utility model.
A kind of sealing structure of pressure sensor as shown in Figs. 1-2, shell 1 and lower end insertion including sensor
The terminal 5 that housing tip is open and is coupled installs sensing element 3,3 lower end of sensing element in the shell 1
O-ring seal 2 is equipped between shell, the 1 top end opening inner wall of shell is equipped with a circle step structure, 5 lower end of terminal
On step structure and the thickness of terminal lower end is greater than the width of step structure, guarantees that 5 lower end a part of terminal is in step
Superstructure, another part are in 3 top of sensing element and compress sensing element 3.
Preferably, by the thickness of sensing element 3, O-ring seal 2 specification and sealing needed for decrement design shell
The height of interior step guarantees that the O-ring seal 2 when pressing of shell 1 is compressed in the reasonable scope, while passing through casing step and limiting
Position guarantee sensing element will not be subject to crushing.
For the utility model using soft wiring board assembly 4 is made of soft wiring board and patch capacitor, soft wiring board is total
It is welded at 4 one end and terminal 5, the other end and the input of sensing element 3, output end weld, and can provide to pressure sensor reliable
Power supply, while pressure sensor output signal.Step is designed inside housings, is directly born against on sensing element by terminal, then
O-ring seal is compressed, guarantees sensor sealing, it is ensured that shell O-ring seal when pressing is compressed in the reasonable scope, platform
Rank limit guarantees that sensing element is not subject to crushing.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
