Description
Technical field
The utility model relates to a kind of automobile NTC temperature sensor, belongs to temperature sensor technology field.
Background technology
The sole energy source that power accumulator runs as pure electric automobile is the core component of electric automobile.In order to make accumulator be in best duty, and getting hold of the state-of-charge of battery at any time, requiring reliably monitor the temperature of accumulator and regulate, to prevent battery from occurring superheating phenomenon, extending its mission life to greatest extent.Although the accumulator of current most of hybrid power/electric automobile adopts temperature sensor, to measure its working temperature, but the temperature sensor for battery modules is that thermistor is fixed on shell by insulating gel, then by shell is arranged on accumulator.Conventional thermistor encapsulates with insulating gel after welding with lead-in wire, because the leg line of thermistor must adopt welding technology with lead-in wire, but leg line is too short cannot be welded again, and the space that temperature sensor is arranged on battery modules is less, therefore after causing the leg line of thermistor to weld with lead-in wire, make thermistor generally within the outside of shell, thermistor is caused to lose the protective effect of shell, because thermistor is also close to the potted end of insulating gel, not only reduce the impact resistance of temperature sensor, then temperature sensor is caused to be subject to the damage of external force, and because of the insulation course of end relatively thin, the dielectric voltage withstand performance of temperature sensor is caused to decline, make its jitter, also reduce the qualification rate of temperature sensor simultaneously.
Summary of the invention
It is little that the purpose of this utility model is to provide a kind of physical dimension, improves the automobile NTC temperature sensor of its dielectric voltage withstand performance and product percent of pass.
The utility model is the technical scheme achieved the above object: a kind of automobile NTC temperature sensor, comprise thermistor, shell and the lead-in wire with insulation course, it is characterized in that: described shell is nickel shell, and shell comprises for holding thermistor and the cylindrical shell of both ends open and the web joint with cylindrical shell one, web joint is provided with through hole, the length L of described cylindrical shell is at 5 ~ 7mm, two leg lines of thermistor weld backward interior bending with respective lead-in wire, thermistor to be placed between two leg lines and to be positioned at the middle part of cylindrical shell, thermistor and lead-in wire side are fixed in cylindrical shell by fluid sealant.
Two leg lines of thermistor are welded backward interior bending with lead-in wire by the utility model, thermistor can be placed between two leg lines, neither affect two leg lines of thermistor and lead-in wire welding operation, effectively shorten again the distance between thermistor and lead-in wire, reduce package dimension, convenient middle part thermistor being fixed on cylindrical shell through fluid sealant, improve the qualification rate of product, under guarantee sensor quick high accuracy thermometric performance, reliably by thermistor encapsulation in the enclosure, improve the impact resistance of thermistor, also because thermistor can seal the middle part being fixed on cylindrical shell, also improve the dielectric voltage withstand performance of temperature sensor, and improve the functional reliability of temperature sensor, .The utility model shell adopts nickel shell, is had the feature of good corrosion resistance and high-melting-point and stable chemical performance, improve life-span and the stability of temperature sensor by nickel shell.The utility model can realize the quick installation of user by the through hole of web joint.
