5a is arranged in parallel with core body 3a, and positioned at positive plate 1a and the edge of negative plate 2a.Improve the overall intensity of battery core, enhancing
Shock resistance.
Specifically, locating rod 5a has four, rectangular distribution.And each locating rod 5a includes that two sections connect from one end is relative
Pole 50a, while the other end of two section pole 50a are respectively fixedly disposed on positive plate 1a and negative plate 2a.
In this example, conducting strip 4a is nickel sheet or copper sheet.It is nickel sheet in this example, it mainly has two benefits：One is convenient weldering
Connect positioning；Two is with good electric conductivity.
In sum, the present embodiment has the advantage that：
1st, divide the rational layout in chamber, reduce the volume of battery.
2nd, by the setting of keeper, it is spaced apart by multiple inner bags, between inner bag and housing, is carried out in each exactly
The positioning of courage, prevents the collision between each part in casing, improves the security performance of battery.
3rd, by the setting of separator, on the one hand further stabilization inner bag, prevents collision；On the other hand extinguishing chemical is passed through
Comprehensively the surrounding of each battery core is surrounded, once separator is destroyed（Fusing, avulsion etc.）, extinguishing chemical can rapid drainage extremely
Burning things which may cause a fire disaster is put out at burning things which may cause a fire disaster, reaches preferable extinguishing effect.
4th, by inner bag, connection moulding, peripheral frame bar setting, be easy to the layout of inner bag to position, while also very convenient inner bag
With the installation and removal of housing.
5th, because of the blast of single core body or burning, and big fire will not be triggered, while by easy-torn line and avoiding hole
Set, water conservancy diversion contact site is easily deformed or comes off under the impact of core body so that disconnecting circuit, manipulate it is very convenient, further
Improve the security of battery.
The above embodiments merely illustrate the technical concept and features of the present invention, its object is to allow person skilled in the art
Scholar will appreciate that present disclosure and implement according to this that it is not intended to limit the scope of the present invention, all according to the present invention
The equivalent change or modification that Spirit Essence is made, should all be included within the scope of the present invention.
