Background technology
Thermal resistor is one kind of sensing element, is divided into positive temperature coefficient thermistor according to temperature coefficient difference
And negative temperature coefficient thermistor (NTC) (PTC).The typical feature of thermal resistor is temperature sensitive, different temperature
Under show different resistance values.Positive temperature coefficient thermistor (PTC) resistance value when temperature is higher is bigger, negative temperature system
Number thermal resistor (NTC) resistance value when temperature is higher is lower, and they belong to semiconductor devices.Core in temperature sensor
Heart component is thermal resistor, and existing temperature sensor application field is extremely wide, wherein just including being installed on battery pack
In temperature sensor.But it is existing poor applied to the temperature sensor stability in battery pack, sensitivity is relatively low, and
Easily fall into when mounted in battery pack, and the temperature sensor after installation easily comes off from battery pack, practicality needs to be carried
It is high.
Utility model content
The purpose of this utility model is in view of the above-mentioned problems, providing a kind of new easily assembling sensitive battery pack temperature sensing
Device, have stable performance, service life grow, easy installation and removal, it is difficult for drop-off after installation the advantages of.
To reach above-mentioned purpose, the utility model employs following technical proposal：This new sensitive battery pack temperature of easily assembling
Sensor is spent, including glass seals single-ended chip, described glass is sealed on single-ended chip and is connected with wire rod, and guarantor is arranged with described wire rod
Sheath, described glass seal single-ended chip one end and passed from one end of protective case, and described protective case seals single-ended chip away from glass
One end has the upper limit lid for preventing that temperature sensor from falling into battery module, is additionally provided with described protective case at least one anti-
The anti-drop structure that only temperature sensor comes off.
Preferably, being provided with the passage penetrated for wire rod in described protective case, glass seals single-ended core on described protective case
One end that piece passes is provided with opening, and described opening diameter is less than the diameter of passage.
Preferably, described upper limit lid includes the spacing cover plate to extension on the outside of protective case.
Preferably, described anti-drop structure includes the anticreep barb being arranged on protective case.
Preferably, described protective case has two symmetrically arranged anticreep barbs.
Preferably, described side of the anticreep barb away from upper limit lid is ramp structure, anticreep barb is close to the upper limit
The side of position lid is planar structure.
Preferably, described protective case is molded by epoxy resin.
Preferably, described glass seals the thermistor that single-ended chip includes being connected with wire rod, described thermistor leads to
Glass is crossed to be packaged.
Compared with prior art, the utility model has the advantage of：Glass seals single-ended chip one end and worn from the end of protective case
Go out, the glass head of thermistor directly can be contacted with measured object, can faster respond measured object temperature change, accurately
Data are spread out of；And it is frangible using protective case fixed installation sensor can then easily to fill, anti-drop structure can prevent from protecting
Set comes off from battery pack, fixed more firm.
Brief description of the drawings
Fig. 1 is the structure chart of the sensitive battery temperature sensor of new easily assembling provided by the utility model.
Fig. 2 is the side view of protective case provided by the utility model.
In figure, glass seals single-ended chip 1, wire rod 2, protective case 3, upper limit lid 4, passage 5, opening 6, spacing cover plate 7, anticreep
