Abstract
The utility model discloses a battery pack connecting sheet with an anti-pulling effect, which belongs to the field of battery connection, and is a strip-shaped metal plate. The battery pack connecting sheet is characterized in that flat parts and buffer arcs which are arranged at intervals are arranged on the metal plate; the edge of each flat part is provided with a downward fixed edge; and a through hole through which a fastening bolt passes is formed in each fixed edge. Compared with the prior art, the battery pack connecting sheet has the advantages that the buffer arcs are additionally arranged on the connecting sheet, so that the battery pack connecting sheet can be flexible in length to a certain extent, is especially suitable for battery module deformation caused by swelling of an aluminum-case battery in a using process, and effectively solves a problem that the connecting sheet is tight and easy to break by pulling. The buffer arcs can effectively reduce traction of the connecting sheet on a battery pole column, can improve reliability of a battery and can ensure reliability and safety of the battery. Besides, the battery pack connecting sheet is simple in structure, convenient to manufacture and low in cost.
Description
Technical field
The utility model relates to a kind of cell connector, particularly a kind of cell connector with tension effect that is applicable to connect aluminum-shell lithium battery pack module.
Background technology
Lithium battery has the advantages such as energy density is large, the life-span long, environment friendly and pollution-free, and cell connects by serial or parallel connection or series-parallel mode the battery pack combining and started to be widely used in power drive field.
At present, what mainly use aspect the connection between electrokinetic cell monomer is strip metal plate, and as shown in Figure 1, 2, in order to guarantee reliability and the fastness of battery pack, that between cell, combines is very tight.And lithium ion battery with aluminum shell pack module in use, cell inevitably has expansion to a certain degree, and distance between batteries monomer battery is increased.Because strip metal plate does not have retractility, pole is produced to very large pulling force, its result or brace are tight easily to be broken, and causes product rejection; Or battery electrode column distortion, cell sealing component damage, works the mischief to battery pack useful life, fail safe.
Utility model content
Technical assignment of the present utility model is for above the deficiencies in the prior art, and a kind of battery pack connection sheet with tension effect is provided, and can resist the tension force that battery cell expands and causes, and improves battery reliability and fail safe
The technical scheme in the invention for solving the technical problem is: a kind of battery pack connection sheet with tension effect, for strip metal plate, it is characterized in that: on described metallic plate, have the par and buffering arc that are intervally arranged, there is downward fixedly edge at described edge, par, and above there is the through hole passing through for clamping bolt on described fixedly edge.
On above-mentioned metallic plate, cushioning arc is one.
On above-mentioned metallic plate, there are a plurality of buffering arcs.
Compared with prior art, the utlity model has following outstanding beneficial effect.
1, on brace, increase buffering arc, can carry out to a certain extent length and stretch, be specially adapted to the battery modules distortion that aluminum-shell battery in use expands and causes, effectively solve the tight problem of easily breaking of brace.
2, buffering arc can effectively reduce brace to battery electrode column tractive, improves the unfailing performance of battery, and guarantees reliability and the fail safe of battery.
3, simple in structure, easily manufactured, with low cost.
Accompanying drawing explanation
Fig. 1 is the brace structural representation of prior art.
Fig. 2 is the structural representation that the brace of prior art is used state.
Fig. 3 is the structural representation of the utility model embodiment 1.
Fig. 4 is the structural representation that the utility model embodiment 1 is used state.
Fig. 5 is the structural representation of the utility model embodiment 2.
Embodiment
Below in conjunction with specification drawings and specific embodiments, the utility model is further illustrated.
As shown in Figure 1, 2, what aspect the connection between electrokinetic cell monomer, mainly use at present is strip metal plate, and in order to guarantee reliability and the fastness of battery pack, that between cell, combines is very tight.And lithium ion battery with aluminum shell pack module in use, cell inevitably has expansion to a certain degree, and distance between batteries monomer battery is increased.Because strip metal plate does not have retractility, pole is produced to very large pulling force, its result or brace are tight easily to be broken, and causes product rejection; Or battery electrode column distortion, cell sealing component damage, works the mischief to battery pack useful life, fail safe.
As shown in Figure 3,4, the utility model brace is strip metal plate, has the par 1 and buffering arc 2 that are intervally arranged on metallic plate, and there is downward fixing along 3 at described 1 edge, par, and described is fixing along there being the through hole 4 passing through for clamping bolt on 3.Take side fixed mode that brace is connected with battery cell electrode 5, bidirectional stress is balanced, has prevented the displacement of battery cell electrode 5.
As shown in Figure 5, embodiment 2 connects for a plurality of battery cells, has a plurality of buffering arcs 2 on described metallic plate, during connection, each par 1 of strip metal plate is connected with battery cell electrode 5, and described buffering arc 2 is between adjacent two electrode 5 tie points.
It should be noted that; particular of the present utility model have been described in detail the utility model; for a person skilled in the art, do not deviating from the various apparent change in spirit and scope situation of the present utility model, it carried out all within the utility model protection range.
