Abstract
The utility model relates to an internal combustion engine coolant temperature sensor which consists of a shell assembly, a plug assembly, a thermosensitive resistor, a internal sealing ring, a sealing washer, sealing material and a heat-conducting medium, and is characterized in that the shell assembly consists of three parts: a shell, a shell pipe and a sealed flat gasket, wherein the shell is spliced, sheathed and connected as well as sealed with the shell pipe; and the shell pipe and the sealed flat gasket are in riveting assembly to be molded and sealed. The internal combustion engine coolant temperature sensor has the advantages that the shell of the temperature sensor is made of steel, so that the assembly and the installation needs are met, and the cost is reduced; the structure of riveting and molding a seamless copper pipe and the sealed flat gasket is adopted by the temperature sensing part of the temperature sensor, so that the heat conduction effect is met, the waste caused by cutting is avoided, the production technique is simplified, and the production cost is reduced; and as a blind hole is not needed to be processed, the processing difficulty is reduced.
Description
Technical field
The utility model relates to explosive motor, is the explosive motor cooling-water temperature transmitter more specifically.
Background technology
The effect of cooling-water temperature transmitter in electric injection system is that the variation with engine coolant temperature is converted to electric signal and is transported to ECU, ECU revises Engine Injection Mass according to the signal (height of engine coolant temperature) of input, to adjust air-fuel ratio, make the combustion mixture flameholding that enters engine, when being cold machine, supply with denseer combustion mixture; Supply with rarer combination gas during hot machine.
At present, known explosive motor cooling-water temperature transmitter housing is the copper housing of monoblock type.Cooling-water temperature transmitter utilizes the thermal conductivity of copper and corrosion resistance to satisfy for a long time in engine-cooling system work.But because the rise of copper material price causes the cost of cooling-water temperature transmitter to increase, the situation of product that has even appearance zero profit.And copper shell is to select for use cold drawn bar copper material to carry out cut to form, and wherein a large amount of copper are cut, and 1/4 of the not enough casing blank of the case weight that is processed into has caused copper material to waste in a large number.
Summary of the invention
The purpose of this utility model is: do not reducing under the product quality premise, by change cooling-water temperature transmitter structure, simplifying production technology, reducing production costs.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of explosive motor cooling-water temperature transmitter, form by housing assembly, plug assembly, thermistor, inner seal ring, packing washer, sealing material, heat-conducting medium, it is characterized in that housing assembly by housing, housing pipe, seal plain cushion three parts and form; Connect and seal for sleeve between housing and the housing pipe; Housing pipe and seal between the plain cushion riveted joint assembling moulding and sealing.
Described housing internal diameter is greater than the housing external diameter of pipe.
Described housing pipe lower end is left and is sealed the groove that plain cushion matches.
The beneficial effects of the utility model are:
1, housing of the present utility model is selected for use steel can satisfy assembling and needs is installed, and has reduced cost;
2, the utility model housing pipe is selected seamless copper pipe for use and is sealed plain cushion riveting molding structure, has promptly satisfied heat-conducting effect, has avoided the waste that brings because of cut, has simplified production technology, has reduced production cost;
3, the utility model reduces difficulty of processing because of having avoided the processing of housing blind hole.
