The most serious.Our eager expectation one cleans the reliable energy and substitutes fossil energy.Along with lithium ion battery
Technology upgrading and the reduction of cost, lithium ion battery is just being widely applied to every field.At present, government tries hard to recommend the most greatly
The development of galvanic electricity electrical automobile, and battery is one of core component of electric automobile, the group technology of low cost is for battery
Development is just particularly important.And battery in groups after total be just one of our requisite element with total negative output,
Therefore seek a kind of reliability height, low cost, highly versatile total the most just and total negative output scheme is the most particularly important.
A kind of new set of cells outfan connector of the invention, highly versatile, connect reliable, can be widely applied to
Between square and soft-package battery group with bolts, use as outfan.
Summary of the invention
For defect of the prior art, it is an object of the invention to provide a kind of set of cells outfan connector.Current
Set of cells total the most just with total negative output terminal connector, have that structure is complicated, connect insecure shortcoming, especially set of cells bolt is even
Connecing, most employing plastic wraps bolts are fixed on connection sheet, or are directly welded at by bolt on connection sheet, and even have is straight
Take hole, overlap bolt when the later stage installs again.First two processing method, complex production process, difficult quality guarantee, cost
High；The third method, technique is old, and production efficiency is low, it is impossible to meet production capacity demand, and quality cannot ensure.The present invention uses
Optimal Structure Designing, uses panel beating one-body molded, and processing technique is simple, and low cost, quality controllable, the later stage is easy for installation.
A kind of set of cells outfan connector provided according to the present invention, connects sheet including connecting bolt, bending, confluxes
Row；
Bending connects sheet and is extended to the top of bus-bar by the outside bending of bus-bar；
It is provided with opening towards the groove inside bus-bar on bending connection sheet；
Connecting bolt is along the normal direction of bus-bar through groove；
Gap is there is between connecting bolt and groove.
Preferably, the upper surface of bus-bar extends boss；Gap is there is between described boss and connecting bolt.
Preferably, described boss is towards the rotation of the nut limiting connecting bolt of connecting bolt.
Preferably, bending connects one end of sheet and connects bus-bar, and it is free end that bending connects the other end of sheet.
Preferably, boss is positioned at the lower section of described free end.
Preferably, bending connects the bending part employing U-shaped structure of sheet.
Preferably, bending connects sheet is panel beating bending part.
Preferably, the height between described free end and bus-bar upper surface is slightly larger than the height of the nut of connecting bolt.
Compared with prior art, the present invention has a following beneficial effect:
1, set of cells outfan connector of the present invention, it is easy to machine-shaping, technique is simple, and intensity is high, can be applicable to multiple
The connection of set of cells outfan.Bolt transfer when the positive stop lug boss gone out on this connector can effectively prevent from fastening, it is not necessary to another
Add the part preventing bolt from rotating again outward.
2, set of cells outfan connector of the present invention, simple in construction, practical, mobilizable bolt is adjustable when tightening
Fastening effect is strengthened in whole position.
3, set of cells outfan connector of the present invention, is applicable to soft as set of cells outfan of part with bolts
Between bag and prismatic batteries, applied range.

Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.Following example will assist in the technology of this area
Personnel are further appreciated by the present invention, but limit the present invention the most in any form.It should be pointed out that, the ordinary skill to this area
For personnel, without departing from the inventive concept of the premise, it is also possible to make some changes and improvements.These broadly fall into the present invention
Protection domain.
A kind of set of cells outfan connector provided according to the present invention, connects sheet including connecting bolt, bending, confluxes
Row；Bending connects sheet and is extended to the top of bus-bar by the outside bending of bus-bar；Bending connect be provided with on sheet opening towards
Groove inside bus-bar；Connecting bolt is along the normal direction of bus-bar through groove；Gap is there is between connecting bolt and groove.
The upper surface of bus-bar extends boss；Gap is there is between described boss and connecting bolt.Described boss towards
Connecting bolt while limiting the rotation of nut of connecting bolt.Bending connects one end of sheet and connects bus-bar, and bending connects sheet
The other end be free end.Boss is positioned at the lower section of described free end.Bending connects the bending part of sheet and uses U-shaped structure.Bending
