Embodiment Construction
[0022] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0023] like figure 1 , figure 2 As shown, a new energy vehicle temperature sensor includes a thermistor 1, a wire 2, a silicone part 3, and an electronic coating 4. The thermistor 1 and one end of the wire 2 are welded together, and the thermistor 1 is externally Insulation encapsulation is carried out by electronic paint 4, a little insulating sheath is stripped off the other end of the wire 2, and the core wire is dipped in tin. The shape of the silicone part 3 is a thin-walled conical cylinder, and the conical cylinder The upper end is open, and a waist-shaped hole is left in the middle of the lower end of the tapered cylinder. There are two protruding ends on the outside of the conical cylinder, and one protruding end is provided with a slot hole. After insulating and encapsulating with electronic paint 4 The thermistor 1 can be penetrated thr...

The invention provides a new energy automobile temperature sensor. The temperature sensor comprises a thermistor, a wire, a silicone rubber member and an electronic coating, the thermistor and one endof the wire are welded together, insulation encapsulation of the external part of the thermistor is performed through the electronic coating, some of an insulation sheath of the other end of the wireis stripped, tin-attaching processing is performed on a core wire, the appearance of the silicone rubber member is a thin-wall tapered cylinder, the upper end of the tapered cylinder is open, a waist-type hole is reserved in the middle of the lower end of the tapered cylinder, the external surface of the tapered cylinder is provided with two extending ends, one extending end is provided with a groove hole, and the thermistor after insulation encapsulation through the electronic coating can penetrate through the groove hole and is located in the thin-wall tapered cylinder. The beneficial effects of the temperature sensor are that the performance is excellent, the structure is simple, the quality is stable, security and reliability are achieved, the installation is convenient, high temperature resistance, oil stain resistance and severe environment resistance are achieved, the chemical stability is good, the thermal response speed is fast, and the sensitivity to the ambient temperatureis high.
Description
technical field [0001] The invention relates to a temperature sensor, in particular to a temperature sensor for a new energy vehicle. Background technique [0002] Sensors are components that convert physical quantities such as temperature, pressure, acceleration, etc. into electrical signals for control system input. Sensors are key components of automotive electronic control systems. They are mainly used in engine control, chassis control, body control and air conditioning systems, cooling systems and navigation systems. They must meet the requirements of accuracy, robustness, manufacturability, interchangeability and low loss. balance between. [0003] The application of general temperature sensors in automobiles mainly includes: measuring air and liquid temperature, measuring engine coolant, fuel, brake and liquid level control temperature, measuring extremely high temperature in catalytic converter in exhaust system, measuring battery electrode temperature, etc. Wait....
