The lower conducting strips are pasted on the upper surface of the rubber pad and are parallel to the short edges of the rubber pad. The cylindrical batteries are connected in series by the upper conducting blocks, the upper conducting strips and the lower conducting strips, and keep favorable electrical connection via the elasticity of the rubber pad.

Description

Voltaic battery

Technical field

The present invention relates to a kind of structure of battery, a kind of Voltaic battery.

Background technology

Model is the battery that the Voltaic battery of 6LR61 comprises the 6 pitch circle cylindricalitys (or rectangle) that rectangular housing, top cover and the inside are being adorned.Cylindrical battery series connection electrode cap back and on the top cover links to each other.In this class battery, cylindrical battery and electrode cap be connected and battery between connection adopt conducting strip spot welding to form.For example 9 volts of rechargeable batteries being introduced of Chinese patent 01234377.3 adopt this structure exactly.This version process operation is more time-consuming, and might produce phenomenons such as rosin joint, dry joint, and reliability is relatively poor, also can produce sometimes the broken phenomenon of box hat weldering.

Summary of the invention

The present invention is intended to propose the structure of the Voltaic battery that the mode of the non-spot welding of a kind of usefulness connects.

This Voltaic battery comprises a rectangular housing, top cover and 6 pitch circle cylindrical batteries, is fixing two electrode caps on the top cover, and 6 batteries become to be connected in series.This Voltaic battery also comprises rubber blanket and three following buss that a block length is square.Rubber blanket is positioned at the bottom of housing, and the protruding circle of 6 circles is arranged on the lower surface of rubber blanket, and the position of protruding circle is relative with the position of the electrode of cylindrical battery.Following bus sticks on the upper surface of rubber blanket, and following bus parallels with the minor face of rubber blanket, and the position of following bus is relative with the position of the electrode of cylindrical battery.The square printed substrate of one block length is arranged below the top cover, the last bus of two printed wires and the last conducting block of two bar printing circuits are arranged on this printed substrate, the position of last bus and last conducting block is relative with the position of the electrode of cylindrical battery respectively.Each is electrically connected the lower end of the electrode cap of top cover with a last conducting block.

When this Voltaic battery is assembled, in the enclosure by the correct polarity cylindrical battery of packing into, the two poles of the earth of each cylindrical battery with last conducting block, last bus, bus contacts down, and cylindrical battery is connected mutually, rely on the elasticity of rubber blanket to keep good electrical connection respectively.Save spot weld operation in the assembling process, simplified operation.

Embodiment

As shown in Figure 1, this Voltaic battery comprises a rectangular housing 1, a top cover 2 and 6 pitch circle cylindrical batteries 6.Fixing two

electrode caps

3,4 on the top cover.It also comprises the square rubber blanket of a block length 8 and three following buss 12.Rubber blanket is positioned at the bottom of housing.As shown in Figure 5, the protruding circle 13 of 6 circles is arranged on the lower surface of rubber blanket 8, the position of protruding circle is relative with the position of the electrode of cylindrical battery.As shown in Figure 4, following bus 12 sticks on the upper surface of rubber blanket 8, and following bus parallels with the minor face of rubber blanket, and the position of following bus is relative with the position of the electrode of cylindrical battery.As shown in Figure 3, the square printed substrate of one block length 5 is arranged below the top cover 2, the last bus 9 of two printed wires and the last conducting block 10 of two bar printing circuits are arranged on this printed substrate, the position of last bus and last conducting block is relative with the position of the electrode of cylindrical battery respectively, and each goes up the lower end of the electrode cap of top cover 11 conducting block 10 and be electrically connected with one.

When this Voltaic battery is assembled, as shown in Figure 1, in shell 1, put into rubber blanket 8 and 6 pitch circle cylindrical batteries 6 successively, cover top cover 2 again, after compressing, top cover and housing are welded together with ultrasonic wave.Assembling is promptly accused and is finished, and has saved spot weld operation, has simplified assembling process.The two poles of the earth of cylindrical battery contact with last conducting block 10, the following bus of going up on bus 9 and the rubber blanket 12 on the printed substrate of top cover respectively, and cylindrical battery is cascaded mutually.The elasticity of rubber blanket 8 makes and keeps good being electrically connected between the cylindrical battery.Protruding circle 13 on the rubber blanket can make each battery evenly stressed separately, can both well contact with bus to guarantee each battery.

As shown in Figure 1, the following bus 12 in this Voltaic battery also can be substituted by the square base plate 7 of a block length.As shown in Figure 7, sole is a bar printing wiring board, and the bus 15 of the printed wire of bus 12 under three replacements is arranged on its upper surface.Base plate only need be stacked in rubber blanket 8 above, do not need to paste mutually with rubber blanket.This structure can make the assembling process of Voltaic battery easier.

As shown in Figure 8, the center of the bottom of the box hat of the cylindrical battery 6 in this Voltaic battery can also become a pointed projection 14.In assembling process, the pointed projection of this on the cylindrical battery will be pressed in the bus or conducting block on the printed substrate, make that the electric contact between them is more reliable.
