Abstract

The utility model discloses a combined battery which comprises a box body, a box cover, battery monomers, a positive external connection body and a negative external connection body, and connecting sheet among battery monomers. Each battery monomer is separately arranged in the box body in an insulation manner; the positive external connection body and the negative external connection body are respectively connected with the positive poles and the negative poles of two battery monomers; and the connecting sheet among battery monomers has a bending shape with the upper end and the lower end thereof respectively connected with the positive poles and the negative poles of two battery monomers. The combined battery provided by the utility model has the advantages of convenient production, environmental protection, stable and reliable quality, and the like.

Description

A kind of assembled battery
Technical field
The utility model relates to a kind of battery, specifically a kind of assembled battery.
Background technology
Assembled battery is in series by several battery cells (generally being three), and shown in Figure 1 being has the 3R12 assembled battery now, and it is in series by three R12 battery cells, 1 positive and negative head and the tail.It is to be welded with copper wire and scolding tin that the inside of each battery cell 1 connects.Because in the welding production process, scolding tin can produce under high temperature action and splashes, be bonded at and mould the box wall and battery is moulded the face of covering, through carrying, vibrations, the tiny scolding tin grain of stick on top has been shaken, and has caused when rocking and can produce certain sound again.And because scolding tin has certain lead tolerance, if solder joint is more, the lead tolerance of entire cell will rise, and an existing 3R12 battery needs 6 solder joints, is unfavorable for environmental protection.In addition, lid 3 adopts directly to cooperate and compresses, and can strike with the hand open, and there is the unstable hidden danger reliably of first quality in product in transportation and use.
Summary of the invention
Technical problem to be solved in the utility model is to propose a kind of easy to make, assembled battery of being beneficial to environmental protection.
For solving the problems of the technologies described above, a kind of assembled battery of the utility model comprises brace between box body, lid, battery cell, the outer junctor of positive and negative electrode and battery cell, described each battery cell is located in the described box body and mutually insulated separates, the outer junctor of described positive and negative electrode links to each other with the positive and negative electrode of two battery cells wherein respectively, brace is bending type between described battery cell, and its upper/lower terminal links to each other with positive and negative the two poles of the earth of adjacent two battery cells respectively.
Above-mentioned a kind of assembled battery, it also comprises inner cap, the upper end of brace is stuck in and covers in described between described each battery cell, is covered in the described lid in described, the top of described each battery cell.
Above-mentioned a kind of assembled battery is fixedly linked by ultrasonic bonding between described box body and the lid.
The utility model is owing to adopted above-mentioned technical pattern, interconnect conducting with brace between each battery cell, thereby need not as existing assembled battery, to link to each other by wire bonds, significantly reduced pad and (only needed two solder joints as the 3R12 assembled battery, be the pad of the outer junctor of positive and negative electrode), thereby can reduce the lead tolerance (as the comparable original reduction by 2/3 of the lead tolerance of 3R12 assembled battery) of battery greatly, not only easy to make, and be beneficial to environmental protection.Brace between each battery cell is covered in being stuck in, only need cover the conducting that inner cap can finish between all batteries monomer during making and connect, very convenient.Be fixedly linked by ultrasonic bonding between box body and the lid, can make product more stable quality in transportation and use reliable.
Description of drawings
Fig. 1 is the structural representation of existing assembled battery;
Fig. 2 is the structural representation in the assembling of the utility model assembled battery;
Fig. 3 is the structural representation after the utility model assembled battery assembles fully.
Embodiment
As shown in Figure 2, assembled battery comprises that three battery cells 1, box body 2, lid 3, inner cap 7, positive pole draw copper sheet 4, negative pole and draw brace 6 between copper sheet 5 and two battery cells, and each battery cell 1 is located in the box body 2 and by the partition walls mutually insulated separately.Positive pole is drawn copper sheet 4 and negative pole and is drawn copper sheet 5 and be weldingly connected with the positive and negative electrode of the battery cell 1 at left and right two ends respectively.Brace 6 is bending type between battery cell, and its upper end is inwardly curved to guarantee its contact performance.The upper end of brace 6 is stuck in the groove of offering on the inner cap 7 between two battery cells.
As shown in Figure 3, during assembling, with inner cap 7 be located in the lid 3, the top of each battery cell 1, again lid 3 is fixedly connected on the box body 2 by ultrasonic bonding, positive pole is drawn copper sheet 4 and negative pole and is drawn copper sheet 5 and pass lid 3 respectively, is exposed to the outside.Like this, the upper end of brace 6 links to each other with the positive pole of a battery cell 1 between battery cell, and the lower end then links to each other with the negative pole of adjacent another battery cell 1, thereby utilizes two braces 6 that three battery cells 1 are together in series.

Claims (3)

1, a kind of assembled battery, comprise the outer junctor of box body, lid, battery cell and positive and negative electrode, described each battery cell is located in the described box body and mutually insulated separates, the outer junctor of described positive and negative electrode links to each other with the positive and negative electrode of two battery cells wherein respectively, it is characterized in that, it also comprises brace between battery cell, and brace is bending type between described battery cell, and its upper/lower terminal links to each other with positive and negative the two poles of the earth of adjacent two battery cells respectively.
2, a kind of assembled battery as claimed in claim 1 is characterized in that, it also comprises inner cap, and the upper end of brace is stuck in and covers in described between described each battery cell, is covered in the described lid in described, the top of described each battery cell.
3, a kind of assembled battery as claimed in claim 1 or 2 is characterized in that, is fixedly linked by ultrasonic bonding between described box body and the lid.
