Description
Technical field
The utility model is related to a kind of auto parts machinery, more particularly to a kind of car engine air admittance temperature sensor.
Background technology
Testing result and is sent to vehicle by the intake air temperature sensor of automobile mainly for detection of the intake air temperature of engine
Computer is carried, if air inlet is that temperature is excessively high, engine can be caused to break down.
Since intake air temperature sensor is used to detect intake air temperature, its long-time is promoted to be in moist environment, therefore,
The leakproofness of intake air temperature sensor is particularly important.
Traditional intake air temperature sensor is mainly by shell, the socket being connect with shell and the temperature detecting resistance in shell
Composition.Although sealing can be achieved in the installation of shell, wet air is easy to be entered in shell by the junction of shell and socket,
To be damaged to the component of enclosure interior, shorten its service life.
Invention content
In view of the deficienciess of the prior art, the utility model provides a kind of good airproof performance, extends its service life
Car engine air admittance temperature sensor.
To achieve the above object, the utility model provides following technical solution：A kind of car engine air admittance temperature biography
Sensor includes shell, the socket being connect with shell, the temperature detecting resistance in shell and the metallic conduction end in socket
Son, it is characterised in that：It is clamped and is connected by clip assembly between the socket and shell, elasticity is equipped between shell and socket
Sealing mechanism, the elastic packing mechanism include the seal groove in inner walls, and seal groove is towards one end in shell
Open end is equipped with installation gap at open end, is installed with cyclic annular limit base at installation gap, cyclic annular limit base has and seal groove
The through-hole of conducting, and the through-hole is less than the diameter of seal groove, and the gasket that may extend to outside through-hole, gasket are equipped in seal groove
There are confined planes between cyclic annular limit base, seal and be equipped with elastic contradictory piece between trench bottom and gasket.
Wherein, elastic contradictory piece is compressed spring, and the outer ring of compressed spring is contradicted with sealing trench bottom and gasket respectively.
Using above-mentioned technical proposal, elastic packing mechanism is arranged by the junction between shell and socket, it is ensured that
The sealing of shell and socket junction, preventing the component in shell from making moist leads to reduced service life.The elastic packing mechanism
In compressed spring it is sustainable gasket is implemented to contradict, ensure to keep stable sealing between gasket and socket.Compress bullet
Spring, as end face is contradicted, can be made the elastic force of compressed spring be not easy to lose, can extend making for compressed spring in this way using its outer ring
With the service life, to further ensure the leakproofness between socket and shell.
The utility model is further arranged to：The splicing position that socket is located at metallic conduction terminal is equipped with sealing shroud, the sealing
Set includes the cyclic annular body being sheathed between socket and metallic conduction terminal, and the axial both ends of cyclic annular body are respectively provided with and ring
The shirt rim that shape body is vertically connected, the end face that cyclic annular body is bonded one end with metallic conduction terminal are cambered surface.
Using above-mentioned technical proposal, setting in this way can guarantee the sealing between socket and metallic conduction terminal.
The utility model is further described below in conjunction with the accompanying drawings.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model embodiment；
Fig. 2 is the portions the I enlarged diagram of Fig. 1.
Specific implementation mode
A kind of car engine air admittance temperature sensor as shown in Figure 1 and Figure 2 includes shell 1, is connect with shell 1

The clamping connection of clip assembly 5, is equipped with elastic packing mechanism 6, which includes to be set between shell 1 and socket 2
Seal groove 11 on 1 inner wall of shell, seal groove 11 are open end towards one end in shell 1, and installation gap is equipped at open end
12, cyclic annular limit base 61 is installed at installation gap 12, cyclic annular limit base 61 has the through-hole 611 be connected with seal groove 11, and
The through-hole 611 is less than the diameter of seal groove 11, and the gasket 62 that may extend to outside through-hole 611, gasket are equipped in seal groove 11
There are confined planes between 62 and cyclic annular limit base 61, elastic contradictory piece 63 is equipped between 11 bottom of seal groove and gasket 62.Bullet
Property contradictory piece 63 be compressed spring, the outer ring of compressed spring 63 is contradicted with 11 bottom of seal groove and gasket 62 respectively.Above-mentioned side
In case, elastic packing mechanism 6 is arranged by the junction between shell 1 and socket 2, it is ensured that shell 1 and 2 junction of socket
Sealing, preventing the component in shell 1 from making moist leads to reduced service life.Compressed spring 63 in the elastic packing mechanism 6
It is sustainable that gasket 62 is implemented to contradict, ensure to keep stable sealing between gasket 62 and socket 2.Compressed spring 63 uses
Its outer ring can make the elastic force of compressed spring 63 be not easy to lose, can extend the use of compressed spring 63 in this way as end face is contradicted
Service life, to further ensure the leakproofness between socket 2 and shell 1.
In order to implement further to seal to it, prevent component impaired.Socket 2 is located at the grafting of metallic conduction terminal 4
Place is equipped with sealing shroud 7, which includes the cyclic annular body 71 being sheathed between socket 2 and metallic conduction terminal 4, cyclic annular
The axial both ends of body 71 are respectively provided with the shirt rim 72 being connected vertical with cyclic annular body 71, cyclic annular body 71 and metallic conduction terminal
The end face of 4 fitting one end is cambered surface.
