And its junction of pin and lead is encapsulated by epoxy resin layer and fixed, high temperature resistant layer of polyurethane is by interior epoxy resin and lead
Sealing is fixed in stainless steel casing, and socket is fixedly connected with high temperature resistant layer of polyurethane.
The temperature sensor of the utility model, stainless steel casing uses diameter shell incremented by successively from front to back, before making
The diameter of piece housing is much smaller than back segment diameter of the housing, on the premise of keeping installation dimension constant, can greatly reduce encapsulation temperature-sensitive
The shell sizes of resistance, when thermistor sealing is in the preceding piece housing of stainless steel casing, make thermistor apart from shell more
Closely, therefore reduce the distance of thermistor and stainless steel casing heat transfer, can also increase contact area now, make reaction speed big
It accelerates greatly, improves the response time of temperature sensor, and improve transducer sensitivity.Outside the cylindricality of the utility model multipath
Shell facilitates and temperature sensor is mounted on washing machine.The utility model by epoxy resin by thermistor and its pin with
The junction of lead carries out encapsulating fixation, then by high temperature resistant layer of polyurethane is fixed on epoxy resin layer and lead-in wire sealing stainless
In outer steel shell, under the premise of ensuring it with reliable sealing performance, good insulation performance and electric property, pass through high temperature resistant
Polyurethane material cushioning effect, the produced influence rocked to temperature sensor when can reduce work have preferable high temperature resistant
And resistance to acid and alkali, the high temperature generated when can be dried with resistance to washing machine, the ageing resistance of temperature sensor is improved, promotes product
Reliability extends product service life, with more prominent superiority in terms of high temperature deformation resistance.
