Description

The apparatus for battery capacity measurement instrument

The utility model relates to a kind of apparatus for battery capacity measurement instrument.

Along with improving constantly of living standards of the people, and the continuous development of science and technology, the widely used various aspects that relate to of battery, particularly to different model, the needs of the battery of different structure all can be seen at any time everywhere.But in use, the electric weight of battery does not just also use up fully and has been abandoned by people often, and its main cause is that people can't know whether also have electric weight in the battery.

The purpose of this utility model is to provide a kind of small-sized battery capacity tester of testing civilian battery.

The purpose of this utility model is achieved in that the apparatus for battery capacity measurement instrument, be by housing, the indication dial plate, movable gage beam, 1～No. 7 battery and button and formula battery gauge head, long-pending accepted way of doing sth battery gauge head, metering circuit constitutes concrete structure: the indication dial plate places surface of shell, circuit places in the housing, movable gage beam flexibly connects by coupling shaft and the watchcase that is arranged on the housing, the both positive and negative polarity of 1～No. 7 battery and button cell gauge head places termination and the housing lower side and the corresponding position, movable gage beam termination of movable gage beam respectively, and long-pending accepted way of doing sth battery measurement head is arranged at the opposite side of watch shell.

The utility model has simple in structure, light owing to adopt said structure, characteristics flexible and convenient to use, this device is applied widely, can test battery, button cell and long-pending accepted way of doing sth battery electric quantity 1～No. 7, is applicable to the various used in battery of family and factory testing.

Provide specific embodiment below in conjunction with accompanying drawing, further specify the utility model and how to realize.

Fig. 1 is the utility model one-piece construction synoptic diagram.

Fig. 2 is the right view of Fig. 1

Fig. 3 is the test circuit schematic diagram

Fig. 4 is the constitutional diagram of measuring 1～No. 7 battery capacity

Fig. 5 is the constitutional diagram of measuring the button cell capacity

Fig. 6 is the constitutional diagram of measuring long-pending accepted way of doing sth battery capacity

As shown in Figure 1 and Figure 2, the apparatus for battery capacity measurement instrument is to be made of jointly the measuring head 4 of housing 1,

indication dial plate

3,2,1～No. 7 battery 7 of movable gage beam and button cell 8, long-pending accepted way of doing sth battery testing head 5, metering circuit.Concrete structure is: indication dial plate 3 places the surface of housing 1, metering circuit places in the housing 1, movable gage beam 2 flexibly connects with housing 1 by the coupling shaft 6 that is arranged on the housing 1, the both positive and negative polarity of 1～No. 7 battery 7 and button cell 8 measuring heads 4 lays respectively at the termination of movable gage beam 2 and the corresponding position, termination of housing lower side and movable gage beam 2, and long-pending accepted way of doing sth battery measurement head 5 is positioned at the opposite side of watch shell 1.

And for example shown in Figure 1, indication dial plate 3 is provided with the not enough viewing area A of electric weight, the not enough warning area B of electric weight, electric weight sufficient district C and button and measures viewing area D, and its indicating gauge hand is connected with metering circuit.

As shown in Figure 3: metering circuit is by resistance R ₁～R ₄, voltage table V constitutes, resistance R ₁, voltage table V, resistance R ₃, resistance R ₄Be connected in series resistance R successively ₂An end be connected resistance R ₁The intersection point place that links to each other with voltage table V, R ₂The other end and resistance R ₄The other end link to each other to constitute measurement terminals S ₁, in resistance R ₃And R ₄The tie point place draw end points S ₂, and resistance R ₁The other end be measurement terminals S ₃, S ₁And S ₂Be the measurement terminals J of 1～No. 7 battery 7 and button cell 8, S ₃And S ₂Measurement terminals I for long-pending accepted way of doing sth battery 9.

As shown in Figure 4, be the constitutional diagram when 1～No. 7 battery 7 of test, wherein positive and negative two utmost points of battery 7 are distinguished the both positive and negative polarity on corresponding meter and the movable gage beam.

As shown in Figure 5, be in the constitutional diagram of testing button formula battery 8.

As shown in Figure 6, be that two of its long-pending accepted way of doing sth battery 9 extremely correspond respectively to the set electrode of housing 1 side in the constitutional diagram of the long-pending accepted way of doing sth battery 9 of test.
