Abstract

The utility model relates to a battery shell. The utility model can expand the AA chargeable battery into the A battery with same appearance and size. The utility model is composed of an insulator outer shell upper ring, an insulator outer shell lower ring, an elastic electric contact piece upper positive electrode and an electric contact piece lower negative electrode. The interior of the battery shell are provided with two AA chargeable batteries which are in parallel connection and supplies the power to combine one A battery. The utility model is repetitively used, and one use method of the AA chargeable battery is changed into two purposes.

Description

Battery shell

The utility model is the device of No. 5 rechargeable battery purposes of a kind of expansion, especially No. 5 rechargeable batteries is transformed into the Battery shell of No. 1 battery.

At present, commonly used flashlight, radio-cassette player, electronic toy, electric shaver and various instrument and meter all need to use battery, and battery not only use amount is big, and kind, specification, model are various, but are to use the most generally No. 1 and No. 5 batteries.Because the size of No. 1 and No. 5 battery differs, and only is applicable to occasion separately, mutually can not be general.

The purpose of this utility model provides a kind of Battery shell, No. 5 rechargeable batteries is packed into serve as battery No. 1 in this Battery shell.

The purpose of this utility model be achieved in that Battery shell by insulator shell Shang Quan, down circle and elasticity electric contact point top electrode are just, the bottom electrode sheet is negative forms.Axially locate in the following circle to have one 8 font hole, No. 5 rechargeable batteries of 2 joints of can packing into, circle can be connected to each other and form the batteries in parallel connection group up and down, has both reduced the internal resistance of battery, increases its electric flux again.Its external form and size equal battery No. 1, reach the purpose of serving as No. 1 battery like this.

Owing to adopt such scheme, No. 5 rechargeable batteries are packed into and just can be acted on the use occasion of No. 1 battery in the Battery shell, can also play the emergent effect of using, and use occasion is not played corrosiveness, can alleviate the pollution of scrap dry battery again, have economy, advantage easy to use environment.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is circuit theory diagrams of the present utility model.

Fig. 2 is the vertical section structural map of first embodiment of Battery shell.

Fig. 3 is the A--A cutaway view of Fig. 2.

Fig. 4 is the vertical section structural map of second embodiment of Battery shell.

Enclose 5. times circle 6. dot 7.J type pin 8.L types among the figure on positive No. 2.5 rechargeable battery 3. bottom electrodes of 1. top electrodes negative 4. and buckle 9.8 font holes, 10. springs, 11. internal and external threads

In Fig. 1, top electrode just (1), No. 5 rechargeable batteries (2), bottom electrode negative (3) is connected to the power supply of batteries in parallel connection group.

At Fig. 2, in embodiment illustrated in fig. 3, top electrode just (1) bottom has two to the elasticity electric contact point that has a downwarp, make it can compress the positive pole of 2 No. 5 rechargeable batteries of joint (2), top electrode (1) is fixed in the circle (4), the J type pin (7) that the lower surface of last circle (4) has 2 symmetries is aimed at down a symmetrical shrinkage pool L type of circle (5) upper end inwall and is buckled (8) oriented towards one another and cooperate, 2 No. 5 rechargeable batteries of joint (2) insert the continuous negative electrode that forms of the 8 same bottom electrodes in font hole (9) (3) side by side during use, last circle (4) is embedded in down circle (5) mutually and has promptly formed No. 1 battery of a joint, during dismounting as long as one pinch and pull out inwards facing to the dot (6) of last circle (4) outer wall with hand.

In another embodiment shown in Figure 4, its external form and measure-alike in No. 1 battery, last circle (4) He Xiaquan (5) is connected by internal and external threads (11), the bottom of top electrode (1) is the positive pole that garden shape electric contact point is connected to 2 No. 5 rechargeable batteries of joint (2) mutually, following circle (5) axially place offers one 8 font hole (9), in can place 2 the joint No. 5 rechargeable batteries (2), on negative (3) the position of bottom electrode, be provided with two springs (10) with respect to 8 font holes (9), No. 5 rechargeable batteries insertions of 2 joints are enclosed in (5) the 8 font holes (9) down, and closing to go up has become one to save No. 1 battery after circle (4) is tightened.

Claims

1, a kind of Battery shell by insulator shell Shang Quan, down the electric contact point top electrode in circle and the circle is just, bottom electrode is negative forms, is characterized in that: can place No. 5 batteries of 2 joints in the sleeve, up and down circle synthetic after external form and measure-alike in No. 1 battery.

2, Battery shell according to claim 1 is characterized in that: top electrode just is being fixed on circle inwall top, the bottom of electrode be a pair of symmetry to the elasticity electric contact point that has a downwarp, circle is that the alignment pin button cooperates up and down.

3, Battery shell according to claim 1 is characterized in that: the bottom of top electrode is a circular electric contact point, encloses up and down by being threaded.
