Abstract
The utility model discloses a very convenient temperature and model detection circuitry of battery package is connected to the signal pin, include: thermistor and model test capacitor, battery package anodal with thermistor's one end link to each other, thermistor's the other end with continuous, the conduct of corresponding end of model test capacitor temperature and model detection circuitry's signal output part, the other end of model test capacitor with the negative pole of battery package links to each other. Because the utility model discloses a mono signal pin structure for the connection of signal pin is very convenient, can not link the mistake, can be applied to widely in the battery package that charges for various electric tool.
Description
Technical field
The utility model relates to a kind of temperature and model testing circuit of electron device, refers more particularly to a kind of temperature and model testing circuit of power brick.
Background technology
At present, for giving the power brick of the electric tool charging such as Charge), charging electric hammer, usually two signal pins are provided with, be respectively used to detect power brick temperature and power brick model, these two signal pins correspond to the fixed resistance value resistance that a NTC thermistor being connected to battery cathode and one are connected to the expression power brick model of battery cathode respectively; Charger or electric tool measure the temperature of power brick by the value detecting described thermistor, and the resistance of the fixed resistance value resistance described in detection determines the model of power brick.This dual signal pin needs when connecting to focus one's attention on, and can not connect mistake.
Utility model content
Technical problem to be solved in the utility model is: the temperature providing a kind of signal pins to connect power brick very easily and model testing circuit.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of temperature of power brick and model testing circuit, comprise: thermistor and model Detection capacitance, the positive pole of described power brick is connected with one end of described thermistor, the other end of thermistor is connected with the respective end of described model Detection capacitance, as the signal output part of described temperature and model testing circuit, the other end of model Detection capacitance is connected with the negative pole of described power brick.
As a kind of preferred version, in the temperature and model testing circuit of described power brick, described model Detection capacitance is polarity free capacitor.
As a kind of preferred version, in the temperature and model testing circuit of described power brick, described power brick is lithium battery bag.
The beneficial effects of the utility model are: the utility model have employed mono signal pin configuration, and structure is more simple, reduces cost, also make the connection of signal pins very convenient, connect mistake never again, thus improve the reliability of connection, reduce labour intensity.
Accompanying drawing explanation
Fig. 1 is the temperature of power brick described in the utility model and the electric principle assumption diagram of model testing circuit.
Embodiment
Below in conjunction with accompanying drawing, describe the temperature of a kind of power brick described in the utility model and the specific embodiments of model testing circuit in detail:
As shown in Figure 1, the temperature of a kind of power brick described in the utility model and model testing circuit, comprise: thermistor R1 and non-polar model Detection capacitance C1, the positive pole of described power brick B1 is connected with one end of described thermistor R1, the other end of thermistor R1 is connected with the respective end of described model Detection capacitance C1, as the signal output part of described temperature and model testing circuit, the other end of model Detection capacitance C1 is connected with the negative pole of described power brick B1.
As everyone knows, due to the premium properties of lithium battery, make it obtain and popularize.Therefore, when practical application, described power brick is generally lithium battery bag.
In sum, be only preferred embodiment of the present utility model, not be used for limit the utility model implement scope, all equalizations done according to shape, structure, feature and the spirit described in the utility model right change and modify, and all should be included in right of the present utility model.
