Set.
According to above scheme, glue-filling slot is offered vertically on the front and rear lateral wall of the maintenance socket.
According to above scheme, the front and rear sides of the maintenance socket lower end are equipped with a glue groove, and two glue grooves connect respectively
Logical locating slot and corresponding glue-filling slot.
According to above scheme, the upper port of the housing is provided with ground strip.
The present invention has the beneficial effect that：The present invention is rational in infrastructure, and thermistor is fixed on casing center area simultaneously by maintenance socket
With heat conduction end contact, the response speed of thermistor is improved；Maintenance socket constitutes the filling part of housing cavity, reduces fluid sealant
Consumption and improve curing rate, shorten the production cycle；The glue-filling slot of maintenance socket both sides makes fluid sealant to penetrate into housing bottom
Insulating protective layer is built, pin weld part and lead are caught in threading hole, and centre bore can increase fluid sealant and lead and weld part
Contact, improves the tensile strength and insulating properties of lead.

Embodiment
Technical scheme is illustrated with embodiment below in conjunction with the accompanying drawings.
As Figure 1-3, a kind of electric heating vessel temperature sensor of the present invention, including housing 1 and thermistor 3,
The housing 1 is that wherein one end of hollow tubular construction and housing 1 is to be equipped with maintenance socket 2 in setting of remaining silent, housing 1,
The lower surface center of maintenance socket 2 be provided with locating slot 21, thermistor 3 be embedded on locating slot 21 so that make thermistor 3 with
The end wall of the closed end of housing 1, which is contradicted, to be set；The closed end end face of the housing 1 is the thermal conductive surface of sensor, and maintenance socket 2 is used
Thermistor 3 is centrally positioned in housing 1 by the locating slot 21 on the cylindrical structure being adapted to housing 1, the lower surface of maintenance socket 2
End face on, the response speed of thermistor 3 can be improved.
Vertical on the maintenance socket 2 to offer two threading holes 22, the upper end of threading hole 22 is through the upper of maintenance socket 2
End face, lower end and the insertion of locating slot 21 of threading hole 22, the pin and lead 31 of thermistor 3 are arranged in threading hole 22；
The threading hole 22 isolates the pin of thermistor 3 and lead 31 with housing 1, so as to improve the exhausted of sensor after packaging
Edge performance.
The wire blocking port 23 of insertion correspondence threading hole 22, institute are offered on the left and right lateral wall of the maintenance socket 2 vertically
