Abstract
The utility model provides a temperature sensor of cooling fluid for the vehicle cooling device, which relates to a temperature sensor. A nylon body is arranged in the hollow copper shell and a pair of platy inserting pins are arranged at the upper part of the nylon body, while the connecting lead wire at the lower part of the nylon body is connected with the thermistance that is arranged at the lower part of the nylon body and an insulating sheath is arranged on the lead wire. The utility model has the advantages of a simple structure, a reasonable design, a long service life, a simple technique and convenience for mounting.
Description
Technical field
The utility model relates to a kind of sensor, relates in particular to a kind of sensor of measured automobiles cooling device temperature.
Background technology
At present, both at home and abroad the automobile cooling temperature sensor is mounted in the water jacket of engine cylinder-body, cylinder cap or the thermostat and stretches in the water jacket, be used for the detection of engine coolant temperature, and its temperature signal inputed to vehicle electronic control unit, for it revises distributive value and injection timing provides foundation.Above-mentioned automobile cooling temperature sensor has the following disadvantages: a. encapsulating material is high temperature resistant, oil resistant and corrosion resistance are poor; B. install inconvenient; C. manufacturing process bothers.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, the cooling-water temperature transmitter that the automobile cooling device of long service life is used.
In order to achieve the above object, the technical solution adopted in the utility model is: nylon body is arranged in the cavity copper shell, position, nylon body middle and upper part is provided with a pair of sheet contact pin, and its lower end part connects lead-in wire and links to each other with the thermistor that be equipped with the nylon body lower end, and lead-in wire is provided with insulating sheath.
The utility model has the advantages that:
Simple in structure, reasonable in design, long service life, technology be simple, be convenient to install.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A portion enlarged diagram of Fig. 1;
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 2 as can be known, the utility model is that nylon body 1 is arranged in the cavity copper shell 3, position, nylon body 1 middle and upper part is provided with a pair of sheet contact pin 2, and its lower end part connects lead-in wire 5 and links to each other with the thermistor 7 that be equipped with nylon body 1 lower end, and lead-in wire 5 is provided with insulating sheath 6.
This thermistor of the utility model lead-in wire has iron husband dragon insulation course, can avoid the bad yield rate that contacts, improves product of thermistor lead-in wire and copper shell, with nylon body thermistor and contact pin assembly are injected into and make in the copper shell that product technology is simple, cost reduces, packing ring is pressed into the screw thread lower end of copper shell, and the sealing effectiveness of sensor in engine is provided.Thermistor is the element that constitutes by to the highstrung semiconductor ceramics matter of temperature working body, this sensor uses negative tempperature coefficient thermistor, when coolant temperature is low, the resistance value of thermistor is big, the signal voltage height of sensor input vehicle electronic control unit, vehicle electronic control unit control engine increases distributive value, otherwise then reduces distributive value.
