Description
Technical field
The utility model relates to the connecting structure of the electric power storage group of a kind of connecting structure of electric power storage group, particularly a kind of double-Y shaped groove structure.
Background technology
According to current battery in daily life, use more and more extensive such as automobile, electric motor car and portable lighting etc., for the voltage that satisfies the electricity consumption facility and the requirement of power stage, usually batteries several even tens are utilized the metallic nickel sheet to carry out serial or parallel connection forming a battery pack, and then can be the electricity consumption facility power.
Continue and consult Fig. 1 and Fig. 2, with connecting structure schematic diagram and the spot welding board spot welding schematic diagram that existing metallic nickel sheet is described, as shown in the figure, the general practice of existing metallic nickel sheet 10 can be by punching press to form vertical bar shape profile groove 12, each vertical bar shape profile groove 12 dual-side can be formed with two welding areas 14, subsequently, spot welding board 16 utilizes the welding area 14 on each vertical bar shape profile groove 12 to be fused to respectively on the electrode 20 of battery 18, can carry out serial or parallel connection battery 18 thus.
Yet the past, this metallic nickel sheet 10 adopted the practice of vertical bar shape profile groove 12, still have many disappearances to produce, at first, if when metallic nickel sheet 10 usable floor areas excessive, will be subject to spot welding board 16 and can only carry out spot welding by single direction, therefore metallic nickel sheet 10 directions of can't overturning easily cause the awkward situation that the vertical bar shape profile groove 12 that is positioned on the middle position can't pinpoint welding procedure.
Continue, as shown in Figure 1, have 3 to take advantage of 3 in totally 9 the situation of vertical bar shape profile groove 12 at hypothesis metallic nickel sheet 10, sequentially have vertical bar shape profile groove 12a, 12b, 12c, 12d, 12e, 12f, 12g, 12h, 12i, and wherein at this, 9 cited vertical bar shape profile groove 12 of the utility model is to illustrate for asking conveniently, but the practical application situation still can be because of the different to some extent differences of demand in battery 18 uses, therefore on the metallic nickel sheet 10 also may be 4 take advantage of 4 totally 16 vertical bar shape profile groove 12 or 5 take advantage of 5 totally 25 vertical bar shape profile groove 12 or above quantity, or just as shown in Figure 1, metallic nickel sheet 10 has 25 vertical bar shape profile grooves 12.
Continue, because spot welding board 16 spot welding principles are to utilize soldering tip 22 to apply electric current and then produce certain temperature at metallic nickel sheet 10, make metallic nickel sheet 10 weldable on the electrode 20 of battery 18, so so practice that can adopt this vertical bar shape profile groove 12 in the past, be to want to make electric current to circulate along the side of vertical bar shape profile groove 12, therefore electric current is unlikely to pass through immediately, so can produce higher temperature, causes more firmly welding of metallic nickel sheet 10 on the electrode 20 of battery 18.
Therefore, when operating personnel are utilizing spot welding board 16 to be soldered vertical bar shape profile groove 12a at point, 12b, after the 12c, the direction that certainly will will change metallic nickel sheet 10 just can be carried out the in addition vertical bar shape profile groove 12g on one side of spot welding, 12h, 12i, yet, just as shown in Figure 2, spot welding board 16 only can move horizontally according to the right and left, therefore, in any case change the direction of metallic nickel sheet 10, the vertical bar shape profile groove 12d of metallic nickel sheet 10 on middle position, 12e, 12f can be difficult to carry out spot welding, in view of this, utilize this vertical bar shape profile groove 12 on Practical Operation, in fact unsatisfactory.
Yet, must consider current trend at design vertical bar shape profile groove 12, as shown in Figure 1, the direction of arrow is current trend, vertical bar shape profile groove 12 on the metallic nickel sheet 10 has on the sense of current different, therefore vertical bar shape profile groove 12 direction differences are subjected to again the restriction on spot welding machine platform 16 operating spaces, the vertical bar shape profile groove 12 on the metallic nickel sheet 10 must be designed to same direction, run counter to profile groove and current design theory yet this is designed with.
In view of this, the utility model people relies on the development Experience of being engaged in for many years related industry, the problem further investigated that faces in the use for existing metallic nickel sheet, rely on large component analysis, and actively seek solution, through the research and development of long-term endeavour, successful utility model goes out a kind of connecting structure of electric power storage group finally, to improve above-described disappearance.
