In code product, such as mobile phone, panel computer and notebook computer etc..Along with the progress of lithium battery technology, mobile base station, electronic
The field such as automobile and energy-accumulating power station the most gradually begins with lithium battery as power supply.
In the research and development and production of lithium battery, temperature is an important parameter, and it is for the manufacture process control of lithium battery
System and performance have important influence.In practice, the measurement for battery temperature is typically with adhesive tape by K-type
Thermocouple is pasted onto on the outer surface of battery, with collecting temperature data.Although the method is simple, but mainly have following some
Not enough.First being poor reliability, adhesive tape bonding is it cannot be guaranteed that thermocouple and the close contact of battery surface, frequent in actual production
There is the problem that both depart from;And during for long-time test, the decline of adhesive tape viscosity also results in thermocouple and battery
Surface bonding loosely.Next to that repeatable poor, during for measuring more battery, battery craft jointing tape meeting one by one
Greatly introduce uncontrollable performance variable, cause the discordance increasing measurement data.It is finally poor accuracy, K-type thermoelectricity
Even end of measuring is usually wire or bar-shaped with armouring protection, and it is " line face " one-dimensional contact with contacting of battery surface,
It is unfavorable for heat conduction and equalizing temperature.For above not enough, develop and can realize thermocouple and lithium battery stably, firmly connect
The switching device touched, carries out the accurate measurement of battery temperature, and research and development and production for lithium battery are to have important actual meaning
Justice.
Utility model content
The purpose of this utility model is to be typically with adhesive tape by K-type thermocouple for the measurement currently for battery temperature
The problem of the drawbacks described above that the mode being pasted onto on the outer surface of battery is brought, and provide a kind of for the survey of lithium battery temperature
The switching device of amount.
For realizing the purpose of this utility model, this utility model be the technical scheme is that
A kind of for the thermometric switching device of lithium battery, described switching device is integral type structure, including preformed hole
And contact surface, thermocouple measurement end inserts the preformed hole of described switching device, to realize the plane-plane contact of thermocouple and this device,
Switching device is fitted by the outer surface of contact surface with lithium battery to be measured, to realize plane-plane contact between the two.
Wherein, described switching device is made up of the metal material that heat conductivity is good, can battery surface temperature quickly be conducted
To thermocouple measurement end.
Wherein, the lithium battery to be measured that described switching device is connected is the battery containing smooth outer surface, including Soft Roll
The outer surface level laminating of dress lithium battery or rectangular cell, described switching device and lithium battery, for plane-plane contact.
Wherein, when lithium battery is flexible package lithium cell when, preformed hole is transverse holes;When lithium battery is rectangular cell
Time, preformed hole is longitudinal hole.
Compared with prior art, thermocouple measurement end and lithium battery to be measured are stablized, are strongly attached to by this utility model
Together, " face, face " contact is changed in common " line face " contact, compensate for adhesive tape bonding loosely, measure position fixing and
Long-time measurement easily loosens and waits deficiency, improves the thermometric reliability of lithium battery and accuracy.
