Abstract
The invention relates to a battery pack comprising a connecting device connected with two batteries. The connecting device is in a strip-type sheet shape and comprises a soldering point arranged on the lower surface of the connecting device and soldered with cathode tabs and a wire joining arranged on the upper surface of the connecting device and connected with an external wire. One surface of the sheet-shaped connecting device is soldered with the cathode tabs of the batteries, and the other surface is connected with the external wire, which avoids that two wires are simultaneously soldered on the cathode tabs of the middles of the batteries and effectively reduces the thickness of the battery pack.
Description
[technical field]
The present invention relates to battery and make the field, relate in particular to a kind of battery pack.
[background technology]
Connect design between traditional battery cell and adopt lead that the lug of two batteries directly is welded to connect, adopt insulating material to be insulated in the junction then.Lug need weld two leads simultaneously in the middle of battery connected, the thickness of whole battery group will certainly increase, simultaneously, attended operation is also inconvenient, cost is higher, profile is not attractive in appearance, and battery pole ear is direct and wire bonds, and high temperature can make the cell sealing place unclamp, thereby battery pack has had bulging leakage, short risk.
[summary of the invention]
Based on this, be necessary to provide a kind of battery pack of thin thickness.
A kind of battery pack, comprise first battery and second battery, described first battery and second battery are provided with lug, also comprise the jockey that is connected with described first battery and second battery, described jockey is that bar shaped is laminar, comprises connecting main body and being arranged on being connected the main body lower surface and being connected the wire joining that the main body upper surface links to each other with external wire with the pad that lug welds with being arranged on.
Preferably, described first battery and second battery comprise aluminium contract film and electric core, the aluminium that described jockey is arranged on described first battery and second battery groove that film and electric core form that contracts.
Preferably, described connection main body comprises first connecting portion and second connecting portion that staggers and connect into " Z " shape, and forms breach; Described first connecting portion and the second connecting portion lower surface are equipped with two pads, respectively with the corresponding welding in the lug position of interconnective first battery and second battery.
Preferably, the thickness of described connection main body is 0.8mm; The described first connecting portion length is 39.5mm, and width is 8.0mm; The length of described second connecting portion is that 32.5mm, width are 8.0mm; First connecting portion staggers with second connecting portion and links to each other, and continuous partial-length is 18.0mm.
Preferably, the inside of described connection main body is provided with Copper Foil, and described Copper Foil one end links to each other with lug, and the other end links to each other with external wire, and two batteries are formed cascaded structure.
Preferably, between described pad and the lug be means of spot welds.
Preferably, the upper surface of described connection main body is provided with 3 external wire contacts.
Preferably, external wire is arranged on the gap position of described connection main body,
Preferably, described connection main body is that insulating material is made.
The lug welding of lamellar jockey one side and battery, another side links to each other with external wire, has avoided welding two leads simultaneously at battery centre lug, effectively reduces the thickness of whole battery group.
Be connected main body between the lug of two batteries and separate certain distance, the short circuit that can avoid traditional welding manner to cause, fail safe is better.
Jockey adopts " Z " shape, and the part with the lug welding does not form breach, can effectively save material, reduces cost; Simultaneously, output lead can be drawn in indentation, there, has further reduced the thickness of battery.
[description of drawings]
Fig. 1 a, 1b, 1c are the structural representation of battery pack.
Fig. 2 a, 2b, 2c are the structural representation of battery attachment apparatus.
Fig. 3 is the structural representation that is connected with the battery pack of external wire.
[embodiment]
Below the structure of main accompanying drawings battery pack.
Shown in Fig. 1 a-1c, battery pack comprises first battery 10, second battery 20 and the jockey 30 that is used to be connected first battery 10 and second battery 20.
The electric core of first battery 10 and second battery 20 and the aluminium film formed groove that contracts is provided with the extreme ear structure of the polarity of drawing electric core.Be depicted as the jockey structural representation of battery pack as Fig. 2 a-2c, the jockey 30 of battery pack is laminar for bar shaped, comprises connecting main body and being arranged on being connected main body lower surface 310 and being connected 3 wire joinings 321,322,323 that main body upper surface 320 links to each other with external wire with 4 pads 311,312,313,314 that two battery pole ears weld with being arranged on.The lug 110,120 of 4 corresponding first batteries 10 of pad difference and the lug 210 and 220 of second battery 20, jockey 30 and lug means of spot welds, can avoid high-temperature soldering to damage battery, and be connected device between the lug of two batteries and separate certain distance, avoid the generation of short circuit.
Connect main body and adopt insulating material to make, comprise that first connecting portion 330 and second connecting portion, 340, the first connecting portions 330 and second connecting portion 340 stagger to link to each other to form " Z " shape that stretches, and the formation breach.First connecting portion 330 and second connecting portion, 340 lower surfaces are equipped with two pads, respectively with the corresponding welding in lug position of first battery 10 and second battery 20.
Be illustrated in figure 3 as the structural representation of the battery pack that is connected with external wire.Three wire joinings 321,322 on the upper surface 320 are connected external wire with 323, and external wire is drawn with external equipment from " Z " shape indentation, there and linked to each other.
The inside that connects main body is provided with Copper Foil, and an end of Copper Foil is connected with the lug of battery, and the other end is connected with external wire, two batteries are formed cascaded structure, be specially wire joining 321 and lug 110 conductings, wire joining 322 and lug 120 and 220 conductings, wire joining 323 and lug 210 conductings.
In preferred embodiment, the thickness of jockey 30 is 0.8mm, first connecting portion, 330 length are 39.5mm, width is 8.0mm, the length of second connecting portion 340 is that 32.5mm, width are 8.0mm, first connecting portion 330 staggers with second connecting portion 340 and links to each other, and the middle partial-length that links to each other is 18.0mm.
The lug welding of lamellar jockey one side and battery, another side links to each other with external wire, has avoided welding two leads simultaneously at battery centre lug, effectively reduces the thickness of battery pack.Simultaneously, thin plate adopts " Z " shape, and the part with the lug welding does not form breach, can effectively save material on the one hand, reduces cost, and simultaneously, output lead can be drawn in indentation, there, has further reduced the thickness of battery; " Z " shape thin plate and battery pole ear are welded to connect safety, easy operating, and good looking appearance, are convenient to promote.
