Row.More valuable be it without using poisonous and hazardous material, it is friendly to environment, obtained increasingly being widely applied.But it
Also there is basic defect, security is bad, the danger for having blast on fire.Each research unit and factory, which all do a lot of work, to be changed
It is apt to its security.It is exactly successful one of comparison that Suzhou peace exempts from welding procedure by the negative pole of power supply company.
It is that column lithium ion battery module generally comprises isolation material and open up the battery of numerous battery plug-in openings thereon
Fixture, the numerous batteries being respectively embedded into each battery plug-in opening series connection piece, while in each embedded battery plug-in opening and with it is each
One parallel-connection network of individual battery series connection piece contact connection, be plugged in respectively in each battery plug-in opening and with corresponding battery series connection piece
The numerous battery cells for being connected and (directly contacting connection or weld).During practical application, these battery cells rely on foregoing parallel-connection network
Parallel with one another, the battery cell realization by foregoing series connection piece with inserting battery clamp opposite side is connected, so will be by multiple electricity
Pond module group assembling forms the lithium ion battery of Large Copacity together.
The core that negative pole exempts from welding procedure is to replace general thin with the sheet metals (battery series connection piece) with multiple bullet pawls
Metal connecting sheet, multiple bullet pawls of sheet metal embrace battery case, realize contact electrical connection.So as to eliminate the weldering to battery case bottom
Connect, eliminate injury of the sweating heat to the internal core component bottom of close to, improve security.
However, conventional batteries series connection piece only by egative film and is integrally disposed upon numerous bullet pawls of egative film surrounding and constituted, use
When, battery case is embraced by pawl is played, contact electrical connection is realized.At least there is problems with：
1st, bullet pawl is relied solely on, it is not enough to the enclasping force of battery, and also the two contact area is smaller, by high vibration mistake
Journey is hit by a bullet pawl and battery by the risk that disengages.
2nd, series connection piece on play pawl structure it is reasonable not enough, its can not well simultaneously with battery clamp and battery cell
The connection of elastic compressive contact, easily there is series connection piece and come off from battery clamp or the problem of battery departs from piece of connecting.
The content of the invention
The application purpose is：In view of the above-mentioned problems, the application propose it is a kind of it is big with battery contact area, to battery enclasping force
Big and piece of being connected with the battery that battery clamp can consolidate combination, and battery series connection piece itself also has very high structure strong
Degree.

" radial direction " mentioned herein, is reference with ring plate 101 unless otherwise instructed.
In circumferencial direction uniform intervals distributions of each the above-mentioned shell fragment 101a that turns up along ring plate 101, each above-mentioned
The circumferencial direction uniform intervals that shell fragment 101b is turned over also along ring plate 101 are distributed.And above-mentioned numerous turn up shell fragment 101a and crowds
Many varus shell fragment 101b are along the circumferential direction alternately arranged with each other.
The ring plate 101 and egative film 102 of battery series connection piece 1 in the making of above-mentioned battery series connection piece 1 for convenience, the present embodiment
For Split type welding structure, i.e. ring plate 101 and egative film 102 and non-monolithic structure, the two is fixedly connected on by welding manner
Together.Specifically, the axial bottom of ring plate 101 is formed with the lower calvus 101d of multiple radially-inwardly bendings, lower calvus 101d and bottom
Piece 102 is welded and fixed.Circumferencial direction uniform intervals distributions of these lower calvus 101d along ring plate 101.
During practical application, the battery modules shown in multiple Fig. 1 are can configure, by each battery cell in one of battery modules
2 upper end (positive terminal) insert in another battery modules the bottom of battery clamp and with battery in another battery modules
Series connection piece connection (if necessary can be welded and fixed the two) in fixture, so realizes being connected in series for two battery modules.It is multiple
Battery modules connection in series-parallel shown in Fig. 1 is combined and constitutes high capacity lithium ion battery.
Each battery cell 2 in these Fig. 1 in battery modules is parallel with one another by parallel connection of metals bar 4, by foregoing string
Battery cell realization of the connection piece with inserting battery clamp opposite side is connected, and is so fitted together multiple battery modules and is formed
The lithium ion battery of Large Copacity.
In order to prevent that battery series connection piece 1 from being compressed power by the axial direction of battery cell 2 and departs from battery plug-in opening, the present embodiment
In, a circle radially-inwardly raised flange (stomidium of bracket holes 301 1 is formed with the hole wall of the bracket holes 301 on insulating support 3
Footpath is smaller and other end aperture is larger, comparison diagram 3 and Fig. 4), the flange is used to limit battery cell and battery series connection piece
Position, prevents battery series connection piece 1 from being compressed power by the axial direction of battery cell 2 and departing from battery plug-in opening.
Because the presence of above-mentioned flange, if egative film 102 is planar structure, it is difficult to be in contact with anode end.
In this regard, the present embodiment has downwardly projecting raised 102a in the middle part punching of egative film 102, the projection is circle, to insert Fig. 1
Battery extreme (being usually positive terminal) and the raised 102a good contacts below middle battery clamp.
It should be noted that this battery series connection piece 1 can also be applied on the battery clamp of traditional structure, and form band
The battery modules of parallel-connection network.
Above-described embodiment is only the technical concepts and features for illustrating the application, and its object is to allow people to understand this Shen
Content please is simultaneously implemented according to this, and the protection domain of the application can not be limited with this.It is all according to the application main technical schemes
Equivalent transformation or modification that Spirit Essence is done, should all cover within the protection domain of the application.
