Description
Technical field
The utility model is related to a kind of improvement of automobile sensor invention more particularly to a kind of automobile multifunctional temperature sensing
The improvement of device is invented.
Background technology
In the prior art, the structure of vehicle steadily sensor uses split type, and 4 springs push down 2 thermosensitive resistor films, modeling
Expect external member insulation, inside filling conduction material is methyl-silicone oil heat conduction, and test process is debugged as heat-conducting medium using silicone oil and produced
Product, efficiency is low, and technique is uncontrollable, and methyl-silicone oil is easy trickling, vertical again after Product Level is placed, methyl-silicone oil aggregation
Slowly, it is necessary to etc. temperature increase to 50 DEG C of case temperatures and can just assemble, respond very slow, error 10%.
Split structure is easily short-circuit, is easy crimp in shell bound edge process internal plastic sheath, and influence performance, high humidity
Under state, the dielectric strength of plastic part reduces, and is easy leaky, directly affects output performance, and temperature accuracy is inaccurate；And point
Body formula shock resistance is not good enough, under the frequency modulation of 0-200HZ, is susceptible to Inner plastic counterpart loose phenomenon, performance
For poor contact.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies of the prior art and provide a kind of automobile multifunctional temperature
Spend sensor.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme that realize：This kind of automobile is more
Function temperature sensor includes shell, it is characterised in that：The shell is plastic material, and two are equipped in the shell
Function foot side by side exports guide post, and function foot output guide post is mutually clamped with shell, and the shell lower end is arranged with copper shell, accordingly
Shell bottom side of the wall is equipped with outer lug boss, and copper shell upper end is coated in outer lug boss, and annular is equipped between outer lug boss lower face and copper shell
Sealing ring is set in the copper shell there are two thermal resistor, and thermal resistor is separately connected function foot output guide post, the copper shell
It is interior to be filled with heat conductive silica gel.
The thermal resistor is sealed into spherical shape using epoxy resin, and lead-out wire equally uses epoxy resins insulation to encapsulate.
The utility model has the beneficial effects that improved automobile multifunctional temperature sensor, temperature measures accurate, insulation
Pressure resistance, parameter stability.
Description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Attached drawing illustrates the structure of the utility model, further illustrates it in relation to details in conjunction with attached drawing below.The automobile
Multi-functional temp sensor, includes shell 1, the shell 1 is plastic material, and two are equipped in the shell 1 side by side
Function foot exports guide post 2, and function foot exports guide post 2 and is clamped with 1 phase of shell, and 1 lower end of the shell is arranged with copper shell 3, accordingly
1 bottom side of the wall of shell is equipped with outer lug boss 4, and 3 upper end of copper shell is coated in outer lug boss 4, is set between 4 lower face of outer lug boss and copper shell 3
There is ring type seal 5, is set in the copper shell 3 there are two thermal resistor 6, thermal resistor 6 is sealed into ball using epoxy resin
Shape, lead-out wire equally use epoxy resins insulation to encapsulate, and thermal resistor 6 is separately connected function foot output guide post 2, the copper shell
Heat conductive silica gel 7 is filled in 3, resistor heat-conducting mode encapsulates 7 using heat-conducting silicone grease, and simple in structure, heat-conducting silicone grease is not easy to trickle,
Temperature rise is fast, woth no need to consider that performance exports waiting problem, solves the problems, such as insulation pressure resistance, parameter stability.
In conclusion the above is only the preferred embodiments of the present utility model only, it is not intended to limit the utility model
Protection domain.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all wrap
Containing being within the protection scope of the utility model.
