Abstract
The utility model belongs to the technical field of a power supply, and provides a cell box of a soft-packaged lithium ion battery. The cell box comprises a bottom box, an upper cover which is connected with the bottom box in a matching manner, and a connecting assembly which is connected to one end of the bottom box and one end of the upper cover. According to the cell box of the soft-packaged lithium ion battery, cells are combined through electrode masts, so that simplicity and convenience in connection can be realized, no special device is used in the connection process, the production efficiency is high, and the reject ratio of the soft-packaged cell in the packaging process is small.
Description
Technical field
The utility model relates to lithium ion battery cell box, relates in particular to a kind of battery core box of soft bag lithium ionic cell.
Background technology
Continuous increase along with lithium ion battery production lot.Large capacity particularly, the increase of great current cell.In order to solve the encapsulation problem of battery, improve the qualification rate of battery production, much battery core factory has all adopted the structure of soft pack cell.Although soft pack cell production qualification rate has improved, group efficiency has declined again, and in connection, pole piece easily fractures, and connects the shortcoming that needs special equipment.In order to solve the problem in groups of battery core, particularly large capacity, the problem in groups of large electric current soft pack cell, need to utilize a kind of device to go to address this problem.
Utility model content
The purpose of this utility model is to exist battery core to connect difficulty for the above-mentioned soft bag lithium ionic cell of the prior art of mentioning, and proposes a kind of battery core box of soft bag lithium ionic cell.
The technical scheme that the utility model solves its technical problem employing is:
A battery core box for soft bag lithium ionic cell, the upper cover that comprises end box and work in coordination with it and connect, and the coupling assembling that is connected to end box and upper cover one end.
Box of the described end and the mutual clamping of upper cover.
Box of the described end is provided with reference column, covers corresponding position on described to be provided with location hole.
Described coupling assembling comprises connecting plate, electrode column and electrode slice, and electrode column and electrode slice connect also injection moulding among connecting plate.
The beneficial effects of the utility model: combine by electrode column between battery core, connect simple and conveniently, connection procedure does not need to use special equipment, and production efficiency is high, and soft pack cell group packet procedures fraction defective is little.
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Accompanying drawing explanation
The stereogram that Fig. 1 is the battery core that is assembled into according to the battery core box of the utility model optimal technical scheme.
Fig. 2 is according to the battery core installation diagram of the battery core box of the utility model optimal technical scheme.
Embodiment
The present embodiment is the utility model preferred implementation, and other all its principles are identical with the present embodiment or approximate with basic structure, all within the utility model protection range.
Referring to Fig. 1-Fig. 2, a kind of battery core box of soft bag lithium ionic cell, comprises end box 10, upper cover 20 and coupling assembling 30.End box 10 is the cuboid of two sides opening, and its limit wall is provided with clamping joint 11, and its bottom surface is provided with reference column 12, and upper cover 20 is the cuboid of two sides opening, and its limit wall is provided with card interface 21, and its bottom surface is provided with location hole 22.Coupling assembling 30 comprise that connecting plate 31, two electrode columns 32 and 33, two electrode columns 32 of two electrode slices and two electrode slices 33 connect and injection moulding in connecting plate 31.
Use the box-packed soft bag lithium ionic cell battery core process of joining of the utility model battery core: the pole piece of two or more soft pack cell 40 and electrode slice 33 use supersonic welders weld; This assembly is put on end box 10, end box 10 closes with upper cover 20 clampings, coupling assembling 30 is clipped in the middle, and installs, and lock screw, forms complete monomer battery core again.Like this, the connection between battery core can be connected with other battery core by electrode column 32, and the connection between battery core is just quite convenient.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, make concrete change or change and all belong to protection range of the present utility model.
