Abstract
The invention discloses a temperature sensor in an ultrasonic welding mode. The temperature sensor is composed of a plug assembly, a shell and a thermistor, wherein the plug assembly is formed by plug sheets and an insulator in an injection molding mode. Firstly, the thermistor is welded on the plug assembly, then the thermistor is placed at the bottom of an inner cavity of the shell in a hung mode, and the plug assembly and the shell are welded together through ultrasonic waves. The temperature sensor in the ultrasonic welding mode has the advantages of strengthening the connecting strength between the shell and the plug assembly, improving the air impermeability, meanwhile, improving the production efficiency, reducing the production cost and being beneficial to automation production.
Description
Technical field
The present invention relates to a kind of temperature sensor, be a kind of temperature sensor that adopts the ultrasonic soldering mode more specifically, be used for measuring the motor intake manifold air themperature, show air themperature in the inlet manifold, control distributive value.
Background technology
Intake air temperature sensor is used very extensive, especially for the measurement of temperature in the automobile inlet manifold.Intake air temperature sensor all adopts structure as shown in Figure 1 at present, is made up of plug assembly, fluid sealant, housing, thermistor.Wherein plug assembly is made of inserted sheet and insulator injection moulding.The characteristics of this structure are: directly with the thermistor wire bonds on plug assembly, thermistor is suspended in the bottom of housing inner chamber, coats fluid sealant at plug assembly and housing junction then.But there is following shortcoming in this kind structure:
One, very high for the requirement of fluid sealant: need strength of joint height, high-low temperature resistant, can long-term work stable in the air;
Two, fluid sealant used the accuracy of measurement height.The fluid sealant consumption very little, then the strength of joint of housing and plug assembly is low, causes plug assembly to separate with housing easily.The fluid sealant consumption is too many, then can influence the temperature sensor performance.
Three, production equipment is required height, and have high input, be difficult for realizing automated production.
Summary of the invention
The objective of the invention is to overcome existing intake air temperature sensor structure, provide a kind of manufacturing process simple, with low cost, well behaved intake air temperature sensor.
The technical scheme that technical solution problem of the present invention adopts is: a kind of temperature sensor that adopts the ultrasonic soldering mode, formed by plug assembly, housing, thermistor, wherein plug assembly is made of inserted sheet, insulator embedding and injection molding, the rear end of thermistor is welded on the plug assembly, the front portion of thermistor is suspended in the bottom of housing inner chamber, plug assembly is corresponding with the joint face place of housing to arrange all projectioies of sharp-pointed ring and groove, and is connected together by supersonic welding.
The invention has the beneficial effects as follows: strengthen housing and plug assembly strength of joint, improve its impermeability, enhance productivity simultaneously, reduce production costs, be beneficial to automated production.
