Abstract
The utility model discloses a novel irregular connecting plate for a lithium ion power battery. The connecting plate comprises a pure nickel plate, wherein a left through hole is transversely formed in the left end of the pure nickel plate, and a right through hole is transversely formed in the right end of the pure nickel plate; a plurality of first solder points are formed at left and right sides of the left through hole, and a plurality of second solder points are formed at left and right sides of the right through hole. The novel irregular connecting plate solves the problems a connecting plate cannot be firmly soldered and is easily busted, the product quality is influenced, the production efficiency cannot be improved and the like in the prior art, and has the characteristics of simple structure, low cost, high product quality, soldering firmness of connecting plate, high production efficiency and the like.
Description
Technical field
The utility model relates to lithium battery technology, is the special-shaped brace of a kind of new type lithium ion electrokinetic cell specifically.
Background technology
Lithium battery is that a class is negative material, the battery that uses non-aqueous electrolytic solution by lithium metal or lithium alloy.At present, for make the combination of large electric current with 18650 lithium batteries, because being connects by nickel sheet, brace is unanimously a difficult point, if have not prison welding with thick brace, fried some equivalent risk, affects product quality, seriously may cause battery risk on fire, production efficiency also can not get improving.
Utility model content
The purpose of this utility model is to overcome the deficiency that above prior art exists, and provides that a kind of simple in structure, low cost, product quality are high, brace firm welding and the high special-shaped brace of new type lithium ion electrokinetic cell of production efficiency.
In order to achieve the above object, the utility model is by the following technical solutions: the special-shaped brace of a kind of new type lithium ion electrokinetic cell, comprise pure nickel sheet plate, pure nickel sheet plate left end is laterally offered left through hole, pure nickel sheet plate right-hand member is laterally offered right through hole, the left through hole left and right sides arranges some the first pads, and the right through hole left and right sides arranges some the second pads.
Described pure nickel sheet plate is rectangle, and pure nickel sheet plate thickness is 3 ~ 5mm.
Described left through hole is located at the centre position of pure nickel sheet plate left end, and right through hole is located at the centre position of pure nickel sheet plate right-hand member, and left through hole and right through hole are symmetrical according to the central shaft of pure nickel sheet plate.
The described left through hole left and right sides arranges respectively three the first pads, and the right through hole left and right sides arranges respectively three the second pads.
Described left through hole and right through hole are strip.
The length of described left through hole and right through hole is 3 ~ 5mm, and the width of left through hole and right through hole is 1 ~ 2mm.
The utility model, with respect to prior art, has following advantage and effect:
1, the utility model has adopted and has comprised pure nickel sheet plate, pure nickel sheet plate left end is laterally offered left through hole, pure nickel sheet plate right-hand member is laterally offered right through hole, the left through hole left and right sides arranges some the first pads, the right through hole left and right sides arranges some the second pads, has that simple in structure, low cost, product quality are high, brace firm welding and a production efficiency high.
2, the utility model, due to left through hole and right through hole being set, stops electric current directly to flow through, and can improve each solder joint electric current, increases welding quality.
3, the utility model is due to some the first pads and the second pad being set, and butt welding point position is fixed, and desertifies, and improves the efficiency of spot welding machine, increases the firmness of pure nickel sheet plate, lowers not prison welding, a fried some equivalent risk. improve the quality of products.

Embodiment
For ease of it will be appreciated by those skilled in the art that the utility model is described in further detail below in conjunction with drawings and Examples.
embodiment:
As shown in Figure 1, the special-shaped brace of a kind of new type lithium ion electrokinetic cell, comprise pure nickel sheet plate 1, pure nickel sheet plate 1 left end is laterally offered left through hole 2, pure nickel sheet plate 1 right-hand member is laterally offered right through hole 3, left through hole 2 left and right sides arrange some the first pads 4, and right through hole 3 left and right sides arrange some the second pads 5.
Pure nickel sheet plate 1 in the present embodiment is rectangle, pure nickel sheet plate 1 thickness is 3 ~ 5mm, left through hole 2 is located at the centre position of pure nickel sheet plate 1 left end, right through hole 3 is located at the centre position of pure nickel sheet plate 1 right-hand member, left through hole 2 is symmetrical according to the central shaft of pure nickel sheet plate 1 with right through hole 3, left through hole 2 left and right sides arrange respectively three the first pads 4, right through hole 3 left and right sides arrange respectively three the second pads 5, left through hole 2 and right through hole 3 are strip, the length of left through hole 2 and right through hole 3 is 3 ~ 5mm, and the width of left through hole 2 and right through hole 3 is 1 ~ 2mm.
During practical application, due to left through hole 2 and right through hole 3 being set, stop electric current directly to flow through, can improve each solder joint electric current, increase welding quality, due to some the first pads 4 and the second pad 5 being set, and butt welding point position is fixed, and desertifies, improve the efficiency of spot welding machine, the firmness that increases pure nickel sheet plate 1, lowers not prison welding, fried some equivalent risk. improve the quality of products.
Above-mentioned embodiment is preferred embodiment of the present utility model; can not limit the utility model; other any change that does not deviate from the technical solution of the utility model and make or other equivalent substitute mode, within being included in protection range of the present utility model.
