Abstract
The utility model discloses a lithium ion power battery with an electrode lead-out structure, which comprises a battery body, wherein a metal casing which is used as electrode materials, is coated outside the battery body; an opening is arranged on the casing; an electrode post of the other electrode of the battery is arranged in the opening and is fixed with the battery body through rivets; the electrode post of the battery is sealed with the metal casing in an insulating mode by an insulating rubber ring. A lead-out metal sheet is outwards arranged on the electrode post of the battery; a definite distance exists between the lead-out metal sheet and the metal casing. When people use a battery and need weld, the utility model can be away from an insulating metal rubber ring; therefore, the quality problem of battery leakage caused by the aging of insulating materials of the electrodes is effectively avoided; besides, people can also directly use a matched inserting component for inserting on the lead-out metal sheet for direct use in order that people can conveniently use the utility model. The utility model has the advantages that welded connection technology is avoided, the using reliability of the battery is improved and engineering implementation of battery users is simplified and is convenient.
Description
Technical field
The utility model relates to a kind of lithium-ion-power cell, particularly relates to a kind of electrode deriving structure of lithium-ion-power cell.
Background technology
The lithium-ion-power cell of the frequent use of people now, the housing that comprises metal, housing is as an electrode, on the housing of metal, have opening, pole as another electrode is arranged in this opening, and by realizing insulated enclosure between insulation cushion rubber and the described housing, the user when in use, just need on the pole of battery, weld lead-out wire, the lead-out wire that welds out is communicated with the electrical equipment of required use battery, this method not only user is operated cumbersome, and the most important thing is because pole is close to the insulation cushion rubber, in the process of welding, the insulating material of the cushion rubber that is easy to cause to insulate is crossed heat ageing, and then causes the quality problems of battery leakage.
The utility model content
At the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of can make welding away from the insulation cushion rubber, effectively avoided insulating material cross heat ageing cause lithium ion battery in the dead of night or the lithium-ion-power cell of seal failure.
The technical scheme that the utility model adopted is: a kind of lithium-ion-power cell that has the electrode deriving structure, comprise cell body, at the cell body skin is the metal shell that is surrounded by as electrode, on described housing, offer opening, the pole of another electrode of described battery is arranged in this opening and by rivet and cell body and fixes, between described battery electrode column and described metal shell, pass through insulation cushion rubber insulated enclosure, draw sheet metal to being outside equipped with on described battery electrode column, there is certain distance in described drawing between sheet metal and the described metal shell.
The described sheet metal of drawing can be welded on the described battery electrode column.
The described sheet metal of drawing can be made up of standing part and extension two parts, described standing part is fixed together by described rivet and described pole, described extension is to drawing away from insulation cushion rubber direction, and described standing part and extension are structure as a whole.
The shape of described standing part can be identical with the shape of described pole.
On described metal shell, also can be connected with the metal lead-out tablet.
Can be provided with a projection on described metal shell, described metal lead-out tablet is connected on this projection.
The end of described metal lead-out tablet can offer connecting hole.
Described sheet metal can be rugosity and outwards draw.
The lithium-ion-power cell that has the electrode deriving structure of the present utility model, because extraction electrode in advance when producing, people are when use needs welding, can be away from the insulated metal cushion rubber, thereby the battery leakage of effectively having avoided the electrode insulation material aging and having caused and the quality problems of seal failure, and the convenience of people in order to use, also can directly select supporting plug-in unit for use, be plugged on the sheet metal of drawing and directly use, avoided welded connection technology, the utility model improves the reliability that battery uses, and simplifies, make things convenient for the engineering construction of battery user.
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Description of drawings
Fig. 1 is the schematic diagram of execution mode one of the present utility model;
Fig. 2 is the schematic diagram of execution mode two of the present utility model.
Embodiment
Shown in Fig. 1-2, lithium-ion-power cell of the present utility model, comprise cell body, outside cell body, be surrounded by metal shell 1 as electrode, on described housing, offer opening, the pole 2 of another electrode of battery is arranged in this opening and by rivet 3 and cell body and fixes, between battery electrode column 2 and 1 metal shell 1, pass through insulation cushion rubber 4 insulated enclosures, as shown in Figure 1, what be welded with a collapsed shape on battery electrode column 2 draws sheet metal 5, this is drawn between sheet metal 4 and the metal shell 1 and has certain distance, draws direction away from insulation cushion rubber 4.
As another execution mode, as shown in Figure 2, draw sheet metal 5 and be made up of standing part 6 and extension 7 two parts, standing part 6 is fixed together by rivet 3 and pole 2, extension 7 is to drawing away from insulation cushion rubber 4 directions, and standing part 6 and extension 7 are structure as a whole.
People's use can be provided with a projection 8 on metal shell 1 for convenience, also is welded with metal lead-out tablet 9 on projection 7, and the supporting plug-in unit that is convenient for people to peg graft uses.
In wiring, use for the convenience of the users, can offer connecting hole 10 in the end of drawing sheet metal 5 and drawing sheet metal 9.
