Description
Technical field
The utility model relates to a kind of battery pack insulation board, is specifically related to a kind of lithium battery group dividing plate, is used for each electric core of lithium battery group at interval.
Background technology
Lithium battery is owing to have advantages such as in light weight, that volume is little, capacitance is big, charging rate is fast, is widely used on all kinds of numbers, the communication product such as notebook computer.
Common single lithium battery core comprises positive and negative plate and positive and negative lug, the electric weight of output is limited, mostly about 3V～4.2V, only can supply with small-sized electronic product, drive on the big product of electric weight demand just not enoughly if will be used for electric motor car etc., a plurality of electric cores need be combined, between each electric core, add dividing plate 1 (insulation board), to prevent the short circuit between the adjacent electric core housing, avoid the generation of potential safety hazard.Described dividing plate 1 is made of the solid thin plate of monoblock, is generally injection mo(u)lding, as shown in Figure 1, 2, when assembling with a plurality of electric cores, a dividing plate 1 is set between each electric core.In the prior art, dividing plate is complete cuboid thin-slab structure, by the mould single injection-molded of making in advance.
Yet, this integrally-built dividing plate in use has problems and is: because battery component is according to the difference of use occasion, size and shape also changes thereupon, thereby the dividing plate that cooperates with it also needs together to change, the dividing plate that cooperates a kind of mold injection molding like this with regard to the battery component that causes a type, the quantity of mould is more, has just improved the manufacturing cost of entire cell assembly.
Summary of the invention
The utility model purpose provides the dividing plate that a kind of suitable polytype lithium battery group is used, and by using the dividing plate of this structure, can reduce the manufacturing cost of lithium battery, and the scope of application, flexibility ratio obtain enlarging and improving.
For achieving the above object, the technical solution adopted in the utility model is: a kind of lithium battery group dividing plate, comprise a body, be respectively equipped with the stitching section that constitutes by a plurality of projectioies or groove at least one pair of symmetrical side of described body, wherein, described stitching section on the side and the stitching section on another side are mutual clamping coupling shape.
In the technique scheme, be clamping coupling shape between described stitching section, the stitching section that is on the side is projection, and another side then is the groove that cooperates with projection, and the position of projection and groove and shape just in time can engagement connections when splicing.In use, according to electric core size to be assembled, select the body of relevant block number, projection on the one body side is inserted in the groove on another body side, the engagement connection of successively respective side being joined, amalgamation becomes the size that needs, so when producing dividing plate, only need a kind of mould of size,, greatly reduce the generation cost according to the different corresponding splicings of use occasion.
In the technique scheme, be respectively arranged with described stitching section on the side around the described body, the described stitching section on adjacent edge is mutual clamping coupling shape.
Another kind of technical scheme is, is respectively arranged with described stitching section on the side around the described body, and the described stitching section on symmetrical limit is mutual clamping coupling shape.
Because technique scheme utilization, the advantage that the utility model compared with prior art has is: the utility model is provided with the stitching section that is made of projection and groove on the side of body, in use, can select the number of body according to the size of waiting to assemble electric core, mutual splicing between corresponding sides is combined into the big or small dividing plate that adapts, and so only needs a kind of mold injection molding of size, greatly reduce the generation cost, enlarged its range of application.
