Abstract
The invention discloses a battery pack, which comprises a plurality of batteries with electrodes, a connecting piece which is electrically connected with the electrodes of adjacent batteries, a leading-out piece welded on an electrode, and an insulating pad attached to the electrodes, wherein the insulating pad is provided with an open piece and a positioning groove is formed at a position corresponding to the open piece; the leading-out piece is extended out of the positioning groove; and the open piece is covered on the leading-out piece. In the battery pack, the leading-out piece is positioned through the positioning groove of the insulating pad, and the insulating pad is convenient for mass production; and the battery pack has relatively low cost.
Description
[technical field]
The present invention relates to a kind of battery, particularly relate to a kind of battery pack.
[background technology]
Battery pack has the lead-out tablet that is welded in battery, and lead-out tablet is used for electrically contacting with outer member as the electrode of battery pack.For different battery pack, lead-out tablet to draw length, angle and position different.Present way is to utilize auxiliary clamp location lead-out tablet, again lead-out tablet is soldered to battery.So, need to make in advance auxiliary clamp, the auxiliary clamp production cycle is longer.And because of the difference of battery pack, used auxiliary clamp is also different, needs the corresponding different auxiliary clamp of making.And need in the auxiliary clamp use to safeguard.Therefore, cause the waste on time and the financial resources, be unfavorable for producing in batches.
[summary of the invention]
In view of this, be necessary to provide the battery pack that a kind of cost is low and be convenient to produce in batches.
A kind of battery pack, comprise some batteries with electrode, be electrically connected adjacent described battery electrode brace and be welded in the lead-out tablet of described electrode, described battery pack also comprises the insulation cushion that is attached at described electrode, described insulation cushion is provided with and hacks and the corresponding described position formation location notch that hacks, described lead-out tablet extends in described location notch, and described hacking is covered on described lead-out tablet.
In a preferred embodiment, a side of described insulation cushion is provided with adhesion, and this side adheres to described electrode.
In a preferred embodiment, described insulation cushion covers described electrode.
In a preferred embodiment, described battery is cylindric, and described insulation cushion is plane that a plurality of circles intersect.
In a preferred embodiment, described lead-out tablet comprises fixed part that is welded in described electrode and the electrical contacts that extends from described fixed part bending, and described fixed part is positioned in the described location notch.
In a preferred embodiment, described location notch is the rectangle of a side openings, and described fixed part is rectangular and be provided with the slit, and described hacking is covered on described fixed part.
Battery pack of the present invention is by the location notch location lead-out tablet of insulation cushion, and insulation cushion is convenient to produce in batches, and cost is lower.
[description of drawings]
Fig. 1 is the part exploded view of the battery pack of an embodiment;
Fig. 2 is the three-dimensional combination figure of battery pack in assembling process shown in Figure 1, and wherein lead-out tablet is positioned in the location notch of insulation cushion;
Fig. 3 is the three-dimensional combination figure of battery pack shown in Figure 1, and wherein hacking of insulation cushion is covered on lead-out tablet.
[embodiment]
Please refer to Fig. 1 to Fig. 3, the battery pack 100 of present embodiment comprises some batteries 1 with electrode 11, be electrically connected adjacent cell 1 electrode 11 brace 2 and be welded in the lead-out tablet 3 of electrode 11.Battery 1 is cylindric, and electrode 11 is positioned at the opposite end of battery 1, is respectively positive electrode and negative electrode.Brace 2 is the metallic conduction material, connects the positive electrode and the negative electrode of adjacent cell 1.
Lead-out tablet 3 also is the metallic conduction material, and it stretches out battery 1.Lead-out tablet 3 is used for electrically contacting with outer member as the electrode of battery pack 100.Lead-out tablet 3 extends in location notch 42, hacks 41 and is covered on lead-out tablet 3.Lead-out tablet 3 comprises fixed part 31 that is welded in electrode 11 and the electrical contacts 32 that extends from fixed part 31 bendings, and fixed part 31 is positioned in the location notch 42, and electrical contacts 32 is electrically connected outer member.The fixed part 31 of present embodiment is rectangular and be provided with slit 311.Lead-out tablet 3 inserts in the location notch 42 from the side of location notch 42 openings, and extend along the direction of insertion of lead-out tablet 3 in slit 311, can so that lead-out tablet 3 strains be convenient to insert in the location notch 42.
During the assembled battery group, at first be welded to connect sheet 2, connect the electrode 11 of adjacent cell 1 to electrode 11; Then insulation cushion 4 is attached at electrode 11, insulation cushion 4 covers electrode 11 and brace 2, makes electrode 11 and brace 2 and exterior insulation isolate; Then lead-out tablet 3 is inserted in the location notch 42 of insulation cushion 4, the fixed part 31 that then welds lead-out tablet 3 is to electrode 11; Afterwards, will hack 41 fixed parts 31 that are attached at lead-out tablet 3, fixed part 31 and exterior insulation are isolated.So, can locate lead-out tablet 3 exactly, easy and simple to handle.Insulation cushion 4 be convenient to produce in batches and cost lower.Insulation cushion 4 can be fitted closely with electrode 11, and is not subjected to the constraint of battery 1 profile.
The above embodiment has only expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
