Abstract
The invention relates to a temperature sensor, in particular to a temperature sensor for an internal combustion engine and a manufacturing method thereof. The temperature sensor mainly comprises a plug assembly, a seal ring, a shell, a thermistor and heat-conducting silicone grease, wherein the thermistor is welded on the plug assembly; the heat-conducting silicone grease is filled into a lower cavity of the shell; and the thermistor is placed in the heat-conducting silicone grease. The temperature sensor is characterized in that a seal silicon rubber layer is formed on the heat-conducting silicone grease. The manufacturing method comprises the following steps of: firstly filling the heat-conducting silicone grease into the shell; filling liquid silicon rubber on the heat-conducting silicone grease so as to seal the silicone grease; inserting the thermistor into the heat-conducting silicone grease before the silicon rubber is solidified; and finally riveting the plug assembly with the shell together after the silicon rubber is solidified. The design structure has the beneficial effect that the problem that the heat-conducting medium flows in the case of transportation or inverted assembly of the heat-conducting silicone grease is solved, thus ensuring the product quality.
Description
Technical field
The present invention relates to a kind of temperature sensor, be specially explosive motor, measure the explosive motor coolant temperature, be used to show engine coolant temperature, control distributive value and control engine water tank cooling fan with temperature sensor and manufacture method thereof.
Background technology
In the prior art, have a kind of explosive motor to reach application with temperature sensor, it is made up of plug assembly, O-ring seal, housing, thermistor, heat-conducting silicone grease.The type product directly is welded in the thermistor lead-in wire on the plug assembly in the world, inserts then and is equipped with in the housing of heat-conducting silicone grease.The defective of this structure is: after the product assembling, deposit if be inverted, can make heat-conducting silicone grease flow to plug direction, make thermistor heat-conducting silicone grease loss on every side, product tilts when mounted or is inverted and installs and uses in addition, all can produce this problem, and the generation of this problem has directly influenced indexs such as product resistivity-temperature characteristics and response time, finally make thermistor can not react the temperature variation of engine fast, cause the inaccurate and displays temperature of Engine Injection Mass to be lower than actual value.
Summary of the invention
The objective of the invention is to use on the temperature sensor technical foundation, its partial structurtes are improved, so that overcome the above-mentioned defective that existing explosive motor exists with temperature sensor at existing explosive motor.
The technical solution adopted for the present invention to solve the technical problems is: a kind of temperature sensor that prevents heat transfer medium flows, building block mainly contains plug assembly, O-ring seal, housing, thermistor, heat-conducting silicone grease, thermistor is welded on the plug assembly, heat-conducting silicone grease is poured in the lower part of frame cavity, thermistor places heat-conducting silicone grease, it is characterized in that also having one deck silicone rubber for sealing on heat-conducting silicone grease; Silicone rubber for sealing above the heat-conducting silicone grease is liquid self-solidifying silicon rubber, its manufacture method is: pour into earlier heat-conducting silicone grease in housing, the silicon rubber of reusable liquid is poured in the top with its sealing of heat-conducting silicone grease, before silicon rubber solidifies, thermistor is inserted in the heat-conducting silicone grease, after treating that silicon rubber solidifies, again plug assembly and housing are riveted together.
Guarantee the sealed silicone rubber seal of product assembling back heat-conducting silicone grease like this, heat-conducting silicone grease can not flow out.Heat-conducting silicone grease around the thermistor is producing or is being inverted under the situation of installing after transportation or the entrucking, heat-conducting silicone grease can not trickle under the sealing of silicone rubber for sealing, has guaranteed that like this product can not make the underproof problem of each performance index of sensor because of the heat-conducting silicone grease trickling again.
The beneficial effect of the design's structure is: solved heat-conducting silicone grease in the problem of transporting or assembling heat transfer medium flows under the inverted situation, guaranteed product quality.
