Abstract
The utility model provides a soldering lug for a battery pack. The soldering lug for the battery pack comprises a lug body, wherein the front end and the rear end of the lug body are provided with a through hole used for ventilating the anode and the cathode of a battery respectively. The soldering lug is characterized in that: the partial lug body which is positioned between the two through holes is retracted inwards to form a neck part. In the soldering lug for the battery pack, the neck part is formed on the lug body and can be effectively fused under special conditions, so that the battery pack and even the whole circuit system are protected. Meanwhile, the utility model provides a solder bump, which can effectively ensure that all the soldering states of all the battery welds are consistent.
Description
Technical field
The purpose of the utility model provides a kind of bonding pad that is used for connecting each battery of battery pack.
Background technology
Along with the day of traditional energy is becoming tight and the deterioration day by day of environment, each state of the whole world is all greatly developing new-energy automobile.At present, the direction of countries in the world (comprising China) development new-energy automobile mainly concentrates on hybrid vehicle and the pure electric automobile.And battery pack is the topmost core drive parts of hybrid vehicle and pure electric automobile.The employed battery pack of existing hybrid vehicle and pure electric automobile is through bonding pad many batteries to be together in series or parallel.Wherein, employed bonding pad great majority do not have any particular design, are exactly common rectangle in view of outward appearance, and therefore, when special circumstances take place, thereby bonding pad can't fuse to battery pack formation protection, and its welding consistency is relatively poor.
Summary of the invention
The purpose of the utility model provides and a kind ofly can fuse the bonding pad that battery pack is protected through the oneself.The further purpose of the utility model is to make the bonding pad that is provided can keep welding consistency.
In order to achieve the above object; The technical scheme of the utility model has provided a kind of battery pack and has used bonding pad; Comprise lamellar body; Have one in order to the through hole to the battery plus-negative plate ventilation in the front-end and back-end of lamellar body, it is characterized in that: the formation neck contracts in the part of lamellar body between two through holes.
Preferably, around said through hole, be distributed with at least two pedestals.
Preferably, have a groove in the front-end and back-end of said lamellar body, groove passes the edge that always extends to said lamellar body behind the said through hole, makes said lamellar body edge form breach.
Preferably, extend a connecting piece respectively at the front end of said lamellar body or the both sides of rear end.
Battery pack that the utility model provided with bonding pad in, on lamellar body, be formed with neck, neck can effectively fuse when special circumstances take place, thereby protection is provided for battery pack even entire circuit system.Simultaneously, the pedestal that provides of the utility model can effectively guarantee the consistency of the welded condition of all battery welds.
Description of drawings
A kind of battery pack that Fig. 1 provides for the utility model is with the structural representation of bonding pad.
Embodiment
For making the utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
As shown in Figure 1, the utility model provides a kind of battery pack to use bonding pad, comprises lamellar body 1, has one in the front-end and back-end of lamellar body 1 in order to the through hole 2 to the battery plus-negative plate ventilation, and contracting in the part of lamellar body 1 between two through holes 2 forms neck 3.This neck 3 can be realized self-fuse protection, thereby to battery pack and even entire circuit system protection is provided.
Around through hole 2, be uniformly distributed with four pedestals 4.Have a groove 5 in the front-end and back-end of lamellar body 1, groove 5 passes the edge that always extends to said lamellar body 1 behind the said through hole 2, makes said lamellar body 1 edge form breach 6, on the both sides of groove 5 two pedestals 4 is arranged respectively.Through pedestal 4 designs, when using the welding machine of some model, can realize accurate welding, guarantee that the welding at each salient point place is even, guaranteed the consistency of all battery weld welded conditions.Through increasing groove 5, make four pedestals 4 of groove 5 both sides allow to produce height difference, in welding process, eliminated error by the supporting surface depth of parallelism, increased the consistency and the fastness of welding.
Extend a connecting piece 7 respectively at the front end of lamellar body 1 or the both sides of rear end, brace 7 is used for connecting two adjacent battery pack of the left and right sides and uses bonding pad.
Existing supposition has 9 batteries that need carry out 3 parallel connections, 3 series connection, is numbered 1 to No. 9 respectively, and enrolls the A string with 1-3 number respectively, enrolls the B string 4-6 number, enrolls the C string 7-9 number.During use, can prepare the bonding pad of 23 (containing three monomer bonding pads) earlier.Welding step is following:
1, the positive pole of No. 1, No. 4, No. 7 battery is welded with the plumb joint downside of article one bonding pad base respectively;
2, the negative pole with No. 2, No. 5, No. 8 batteries welds with another place's plumb joint downside of article one bonding pad respectively;
3, the positive pole of No. 2, No. 5, No. 8 batteries is welded with the plumb joint downside of second bonding pad base respectively;
4, the negative pole with No. 3, No. 6, No. 9 batteries welds with another place's plumb joint downside of second bonding pad respectively;
So just accomplished the welding of 3 parallel connections, 3 series connection of 9 batteries.
