Equipped with the through-hole passed through for conducting wire two.Sheath is divided into bull and parent part, is attached by the way of grafting between the two, if you need to
Repair replacement, can directly be plugged, it is very convenient, and parent part in be arranged sealing element in the middle part of through-hole for
Conducting wire two passes through, and sealing element improves waterproofness for being sealed to the other end of sheath.
In above-mentioned electric car temperature-detecting device, the temperature sensor is NTC thermistor, the conducting wire one
Quantity be that one end of two and two conducting wires one is connected to two connecting pins of the NTC thermistor.Temperature sensing
Device has the characteristics that service life length, vibration resistance and anti-interference using NTC thermistor.
In above-mentioned electric car temperature-detecting device, the length of the every conducting wire one is 3~20mm.Each wire
One is shorter, so that the NTC thermistor for being connected to conducting wire one end is not susceptible to shake, detects more accurate.
In above-mentioned electric car temperature-detecting device, the outside of the NTC thermistor is using epoxy resin enclosed.
Epoxy resin enclosed mode makes have good waterproof performance at NTC thermistor, while not influencing NTC thermistor again
Detection to temperature.
In above-mentioned electric car temperature-detecting device, the terminal is fixed on the sheath by clamp.Pass through
Terminal is fixed on sheath by clamp, stable connection, convenient for disassembly and assembly.
As another situation, in above-mentioned electric car temperature-detecting device, the terminal is described by being threaded through
Fastener on sheath is fixed on sheath.According to differently demand, fastener can also be directlyed adopt and tighten terminal, fix it
On sheath, easy disassembly.
Compared with prior art, this electric car temperature-detecting device is by by NTC thermistor, terminal and sheath phase
The mode of connection is realized by terminal to NTC so that the conducting wire connected between NTC thermistor and control chip is divided into two sections
The position of thermistor supports, without be in addition arranged it is dedicated grip structure, also avoid conducting wire it is too long caused by winding
The case where interference, facilitates the dismounting to this electric car temperature-detecting device；Meanwhile sheath be divided into the bull that is mutually inserted and
Parent part only needs simply to plug in dismounting, and use is more convenient.
