Embodiment
Below, with reference to Fig. 1 and Fig. 2, the embodiment of implementing charging device of the present invention is described.In this Fig. 1 and Fig. 2, illustrating corresponding to the additional identical label of the part of Fig. 3 and Fig. 4.
In this example, as shown in Figures 1 and 2, anodal charging terminal 1a and negative pole charging terminal 1b are set in the battery installation unit 8 of charging device 1, and positive terminal 2a and negative terminal 2b that they are connected to the battery component 2 that constitutes battery (secondary cell) do not touch this positive pole charging terminal 1a simultaneously and switch terminal 1d are set.
In this case, in this example, the positive terminal 2a of battery component 2 and the contact portion of negative terminal 2b are for as shown in Figure 2, be made as the plane of prescribed level, anodal charging terminal 1a, negative pole charging terminal 1b and switch terminal 1d with charging device 1 is made of the line spring separately as illustrated in fig. 2 simultaneously, and making the distance between this positive pole charging terminal 1a and the switch terminal 1d is the distance that can contact the positive terminal 2a of battery component 2 simultaneously as shown in Figure 2 when being installed in battery component 2 in the battery installation unit 8.
That is, when this battery component 2 being installed in the battery installation unit 8 of charging device 1, as shown in Figure 2, with this positive pole charging terminal 1a and switch terminal 1d by short circuit in the positive terminal of battery component 2.
And anodal charging terminal 1a, the negative pole charging terminal 1b of this charging device 1 and switch terminal 1d also can not be the line springs, but leaf spring.
In this example, this switch terminal 1d is connected to the base stage of the control electrode of the npn transistor npn npn 11 that switch uses by resistor 10, the collector electrode of a controlled electrode of this switching transistor 11 is connected to by resistor 4 is provided for example power supply terminal 5 of the direct voltage of 3V, simultaneously the collector electrode of a controlled electrode of this switching transistor 11 is connected to control charging action control microcomputer 6 have or not battery detecting terminal 6a.And, with the grounded emitter of another controlled electrode of this switching transistor 11.
And, in this example, provide for example charging voltage of 4.2V to the anodal charging terminal 1a of this charging device 1, simultaneously with negative pole charging terminal 1b ground connection.Other and existing known charge device similarly constitute.
Yin Ben is the above formation for example, so when battery component 2 is not installed in the battery installation unit 8 of charging device 1, the switch terminal 1d of charging device 1 is open circuit, switching transistor 11 is for ending, the collector voltage of this switching transistor 11 is 3V, what the direct voltage of this 3V offered control microcomputer 6 has or not battery detecting terminal 6a, control microcomputer 6 this moment and judge that battery component 2 is not installed in the battery installation unit 8 of charging device 1, the control of the action of not charging.
And when battery component 2 is installed in the battery installation unit 8 of charging device 1, as shown in Figure 2, because the anodal charging terminal 1a of charging device 1 contacts and short circuit with the positive terminal 2a of battery component 2 with switch terminal 1d, so the voltage of anodal charging terminal 1a for example 4.2V offers the base stage of switching transistor 11, this switching transistor 11 becomes conducting, the voltage of the collector electrode of this switching transistor 11 becomes about 0V, what the voltage of this about 0V offered control microcomputer 6 has or not battery detecting terminal 6a, control microcomputer 6 this moment and judge that battery component 2 is installed in the battery installation unit 8 of charging device 1, the control of the action of charging.
According to this example, owing to the anodal charging terminal 1a that does not touch battery installation unit 8 is provided with switch terminal 1d, when in this battery installation unit 8, battery component 2 being installed, by should positive pole charging terminal 1a by the positive terminal 2a short circuit of this battery component 2 and switch terminal 1d make this microcomputer 6 detect the installation of these battery components 2, so need not to be provided with mechanical switch 3, and need not in battery component 2, to be provided with unnecessary terminal 2c and thermistor 7, also can detect in the battery installation unit 8 of charging device 1 battery component 2 has been installed.
And, in above-mentioned example, discussed and relevantly do not touched the anodal charging device 1a of charging device 1 and the example of switch terminal 1d is set, but can easily understand, replace above-mentioned mode, do not touch negative pole charging terminal 1b and switch terminal 1d is set, this negative pole charging terminal 1b is contacted and short circuit with the negative terminal 2b of battery component 2 with switch terminal 1d, as long as use the transistor (for example pnp transistor npn npn) of opposed polarity, then can obtain the effect identical as switching transistor with above-mentioned execution mode.
The invention is not restricted to above-mentioned example, much less, under the situation that does not break away from main spirit of the present invention, can adopt other various structures.
