Abstract
The invention provides an electronic water temperature sensor. The electronic water temperature sensor comprises an induction head; the right end of the induction head is provided with a connecting portion; an induction chip is arranged inside the induction head; the right end of the connecting portion which is taper-shaped is provided with a hexagonal nut; the outer surface of the connecting portion is provided with taper pipe threads; the hexagonal nut only needs to be twisted to achieve threaded connection of the connecting portion and an engine coolant tank; the inner wall of the right side of the hexagonal nut is provided with a sealing ring; the right end of the induction chip is connected with an insertion joint head through leads; the right side of the insertion joint head is provided with an insertion joint hook. Heat conduction is performed through the induction head and the induction chip is utilized to perform induction to transmit signals to the insertion joint head through the leads and ultimately the signals are transmitted out through the insertion joint hook. The electronic water temperature sensor has the advantages of being simple in structure, low in manufacturing cost and high in sensitivity, being capable of playing a role of detecting the temperature of automotive engine coolant, effectively avoiding mechanical vibration from interfering temperature detection, being high in accuracy and the like.
Description
Technical field
The present invention relates to the automobile sensor technical field, be specifically related to a kind of electronic type cooling-water temperature sensor.
Background technology
Along with the development of science and technology, towards future developments such as safe, robotization and intellectualities, it is also comparatively general that sensor technology uses on automobile automotive field gradually, and for example crankshaft position sensor is in order to detect the rotating speed of bent axle and engine; Lambda sensor offers ECU as controlling fuel oil or near the reference signal of air ratio optimum value in order to detect the oxygen concentration in exhaust; Intake air temperature sensor offers in order to detect intake air temperature the density that the ECU class is calculated air; Cooling-water temperature sensor is in order to detecting the temperature of engine coolant, and offers ECU temperature signal etc.
And existing cooling-water temperature sensor, the mechanical contact cooling-water temperature sensors that adopt sense resistance and magnet-sensitive switch to be bundled together more, this structure makes sense resistance separate with shell body, the temperature that detects is inaccurate, and reaction is slower, and sensitivity is relatively poor, and automobile has vibration in motion process, unavoidably can affect to mechanical cooling-water temperature sensor, make temperature detection result inaccurate, error is larger.
Summary of the invention
It is a kind of simple in structure, low cost of manufacture, highly sensitive that technical matters to be solved by this invention is to provide, and can play and detect automobile engine cooling liquid temperature function and the higher device of degree of accuracy, i.e. a kind of electronic type cooling-water temperature sensor.
Technical matters to be solved by this invention realizes by the following technical solutions:
A kind of electronic type cooling-water temperature sensor comprises inductive head, and the right-hand member of described inductive head is provided with connecting portion, and its inside is equipped with induction chip; The right-hand member of described connecting portion is provided with hexagonal nut, and described connecting portion is tapered, and its outside surface is provided with taper-thread, by the turn hexagonal nut, can realize being threaded of connecting portion and engine coolant case; The right side inwall of described hexagonal nut is equipped with O-ring seal; The right-hand member of described induction chip is connected with connection-peg by wire; The right side of described connection-peg is provided with to peg graft and hooks.By inductive head heat conduction, and utilize induction chip to respond to, signal is passed to connection-peg by wire, finally hook by grafting signal is passed.
Described inductive head, connecting portion and hexagonal nut are made by copper product, adopt the heat conductivility of copper product better, the temperature of liquid coolant can be passed to induction chip, have improved the accuracy of temperature detection.
Described O-ring seal is made by elastomeric material, and O-ring seal prevents that in order to realize sealing liquid from entering the inside of inductive head, connecting portion and hexagonal nut, plays the effect of protection induction chip.
The invention has the beneficial effects as follows: the present invention has the advantages such as simple in structure, low cost of manufacture and sensitivity height, can play the function that detects the automobile engine cooling liquid temperature, has effectively avoided the interference of mechanical vibration for temperature detection, and degree of accuracy is higher.
