Abstract
The utility model provides a novel battery pack with an insurance function, which is formed by a connection of a plurality of single batteries. Connecting slices are arranged between the plurality of single batteries, and two ends of the connecting slices are arranged on electrode connecting points of the single batteries. A nickel strap which is narrower than the two ends arranged on the middle of the connecting slices. The novel battery pack with the insurance function adopts the connecting slices provided with nickel straps, so that the connecting slices can be fused instantly when the plurality of single batteries are short-circuited so as to protect other batteries from being damaged. Meanwhile, shadow lines with pits are arranged on the electrode connecting points, so that the connecting slices are welded more firmly.
Description
Technical field
The utility model relates to battery, and a kind of specifically electrode connecting piece can fuse automatically, and has the novel battery group of insurance function.
Background technology
At present, employed battery pack generally is in series by a plurality of cells on the market, in the process of assembled battery, has good electrical conductivity between the battery in order to make, the positive and negative electrode of battery adopts nickel strap to connect, and the manufacturing cost of nickel strap is higher, is not easy to extensive use.Therefore, industry generally adopts the brace of nickel plated steel strip as the battery positive and negative electrode, and nickel plated steel strip has excellent conducting performance, and its manufacturing cost is cheaper, still, in use has the deficiency of following two aspects:
1, the fusing point of nickel plated steel strip is higher, battery pack wherein short circuit phenomenon appears in a cell time, when needing the discharging current of battery pack to reach very big, nickel plated steel strip could fuse, its insurance function a little less than, be easy to cause the damage of whole battery group.
2, nickel plated steel strip has elasticity, after the positive and negative electrode with battery welds, comes off easily.
Summary of the invention
At above the deficiencies in the prior art and defective, the purpose of this utility model is to provide a kind of novel battery group with insurance function.
The purpose of this utility model is achieved by the following technical solution:
A kind of novel battery group with insurance function, connect to form by a plurality of cells, be provided with brace between this cell, the electrode tie point of cell is located at the both ends of described brace, and the position, intermediate portion is provided with the nickel strap of one section width less than the both ends width.
As optimal technical scheme of the present utility model, the electrode tie point of described cell is provided with a plurality of concave points.
As optimal technical scheme of the present utility model, described a plurality of concave points are arranged in the electrode tie point uniformly.
Compared with prior art, the brace of nickel strap in the middle of adopting, the utility model is set, when cell is short-circuited; but moment fusing; protect other battery not to be damaged, and the electrode tie point is provided with the dark flower of concave point, can makes the more firm of brace welding.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is the structural representation that the utlity model has the novel battery group of insurance function.
Fig. 2 is the structural representation of brace that the utlity model has the novel battery group of insurance function.
Fig. 3 is the structural representation of cell that the utlity model has the novel battery group of insurance function.
Fig. 4 is the enlarged diagram of a-quadrant among Fig. 3.
Embodiment
See also Fig. 1, be the structural representation of the novel battery group that the utlity model has insurance function.This has the novel battery group of insurance function, is connected to form by a plurality of cells 101, and present embodiment is an example with two, is illustrated.Be provided with brace 102 between this cell 101, the both ends 1021(of this brace 102 sees also Fig. 2) be located at the electrode tie point 103 of cell 101.
See also Fig. 2, be the structural representation of the brace of the novel battery group that the utlity model has insurance function.The middle part of brace 102 is the nickel strap 1022 of one section width less than both ends 1021 width, when wherein a cell 101 is short-circuited, but nickel strap 1022 moments fusing, the circuit that cuts off battery pack protects other battery not to be damaged.The width of nickel strap 1022 can be provided with according to the size of battery power discharge electric current.For example, the discharging current of battery pack is 30AH, and the width of nickel strap can be made as 1.7 microns.
See also Fig. 3 and Fig. 4, be the enlarged diagram of a-quadrant among the structural representation of the cell of the novel battery group that the utlity model has insurance function and Fig. 3.The electrode tie point 103 of cell 101 is provided with a plurality of concave points 104, this concave point 104 is arranged in 103 formation one of electrode tie point uniformly and secretly spends the zone, when the end 1021 of brace 102 is welded on the electrode tie point 103, can make the position of welding more firm, prevent that brace 102 from coming off.
The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Every equivalence of doing according to the utility model changes and revises, and is all covered by the scope of the utility model claims.
Claims (3)
1. novel battery group with insurance function, connect to form by a plurality of cells, be provided with brace between this cell, it is characterized in that: the electrode tie point of cell is located at the both ends of described brace, and the position, intermediate portion is provided with the nickel strap of one section width less than the both ends width.
2. the novel battery group with insurance function according to claim 1 is characterized in that: the electrode tie point of described cell is provided with a plurality of concave points.
