Accompanying drawing herein is merged in description and constitutes the part of this specification, it is shown that meet the enforcement of the application
Example, and for explaining the principle of the application together with description.
Detailed description of the invention
Below by specific embodiment and combine accompanying drawing the application is described in further detail.
As shown in figs. 1-7, the embodiment of the present application provides a kind of bus structure, and it includes busbar 10 and pin 20, draws
Foot 20 is for electrically connecting with the lug of battery core, then is conducted to outside battery core by inside by battery core electric current by busbar 10.
Offering mating groove 100 on busbar 10, the shape of this mating groove 100 can select flexibly, such as arcuate groove etc..
Pin 20 includes body 200 and the extension board 201 fixed with body 200, and this extension board 201 can extend into aforementioned cooperation groove
In 100, and this mating groove 100 is fixed with extension board 201 and is connected.Specifically, mating groove 100 and extension board 201 can use weldering
The mode such as connect is fixed.Preferably, extension board 201 can be fixedly connected on the side of mating groove 100, with improve extension board 201 with
Fixing intensity between mating groove 100.
The side of above-mentioned mating groove 100 refers to and removes the part beyond its bottom surface on mating groove 100, and this bottom surface is then
The face relative with the opening part of mating groove 100.When using welding manner, after having welded, will be at mating groove 100 and extension board
Forming weld seam between the outer surface of 201, the width of this weld seam can be 0.2mm.For the weldering between busbar 10 and pin 20
Connect, can be in the way of using laser welding, to improve welding quality.
After using above-mentioned bus structure, owing to the quality of fit of extension board 201 with mating groove 100 is easier to control, therefore
Operation when processing busbar 10 and pin 20 and both be assembled together is fairly simple.So, adding of this bus structure
Work difficulty is relatively low.
In a kind of embodiment, the cell wall of above-mentioned mating groove 100 can include the first plane 100a, the second plane being sequentially connected with
100b and the 3rd plane 100c, this first plane 100a and the 3rd plane 100c are positioned opposite, and mating groove 100 is flat by first
Face 100a, the 3rd plane 100c are fixing with extension board 201 to be connected.The cell wall of mating groove 100 is designed as multiple flat by this embodiment
The structure that face is combined, owing to the processing technique of the first plane 100a, the second plane 100b and the 3rd plane 100c is fairly simple,
Quality of fit between itself and extension board 201 is easier to be guaranteed, and therefore, this kind of mating groove 100 can drop to a greater degree
The difficulty of processing of low bus structure.
In order to simplify the structure of mating groove 100, mating groove 100 can be set to linear type through slot, this linear type is through
The opposite sides of the through busbar of groove 10.It is straight line that linear type through slot herein refers to the extension line of mating groove 100, should
Mating groove 100 is along the through busbar in direction 10 of self extension line.At this point it is possible to cooperation is put in the one end that will extend over plate 201
One end of groove 100, and gradually promote pin 20 so that extension board 201 stretches into mating groove along the extension line direction of mating groove 100
In 100.It addition, this kind of mating groove 100 can also expand the connection area of extension board 201 and busbar 10, increase whole with this
The area of passage of bus structure.
When mating groove 100 is set to linear type through slot, when implementing the assembly manipulation of busbar 10 and pin 20, can
In the way of by range estimation, guarantee the extension board 201 position relative to mating groove 100, but this kind of mode will cause operator
Need to spend the more time with the relative position guaranteeing between extension board 201 with mating groove 100.In order to shorten busbar 10 with
The installation time of pin 20, pin 20 may also include limiting plate 202, and this limiting plate 202 is connected to body 200 and extension board 201
Between, and limiting plate 202 connects along bearing of trend and the busbar location gear of mating groove 100.After being arranged such, operator are only
Need to promote pin 20, when limiting plate 202 and busbar 10 position gear connect time, then stop promoting pin 20, then will extend over plate
201 are secured together with busbar 10.
It is to be appreciated that the gear of above-mentioned limiting plate 202 and busbar 10 connects position and can only exist in the one side of limiting plate 202,
But, the reliability spacing in view of one side is relatively low, therefore can be respectively provided with stopper protrusion in the opposite sides of limiting plate 202,
Two stopper protrusions position gear respectively and are connected to the opposite sides of mating groove 100.Owing to the distributing position of two stopper protrusions is for joining
Closing the opposite sides of groove 100, therefore during spacing, the force ratio between stopper protrusion with busbar 100 is more equalize, with
This reaches object defined above.
Relative position relation between aforementioned body 200, extension board 201 and limiting plate 202 can be arranged, flexibly for letter
Change the processing technique of pin 20, body 200 connects the part of limiting plate 202, limiting plate 202 and extension board 201 flush.Ginseng
According to Fig. 6 and 7, the part that body 200 connects limiting plate 202 can be the top of body 200, and end face and the bottom surface at this top are equal
Can be plane, and limiting plate 202 and extension board 201 can use flat board so that the end face of aforementioned top, the top of limiting plate 202
In the end face of face and extension board 201 is generally aligned in the same plane, the bottom surface of aforementioned top, the bottom surface of limiting plate 202 and extension board 201
In bottom surface is generally aligned in the same plane, simplified the processing technique of pin 20 by the structure simplifying pin 20 with this.Certainly, pin 20
Integrated mode can be used to process, to improve the structural strength of pin 20, and simplify the processing technique of pin 20 further.
Previously mentioned, when mating groove 100 is set to linear type through slot, the area of passage of bus structure can be increased.
Based on the area of passage this purpose increasing bus structure, it is also possible to make extension board 201 extend to join from one end of mating groove 100
Close at the other end of groove 100, increase the area that coordinates between extension board 201 and mating groove 100 with this as far as possible, and then increase is confluxed
The area of passage of structure.As it is shown in figure 1, in one preferably embodiment, the end of extension board 201 and the end of mating groove 100
Flush, obtains the area of passage of maximum with this on the bearing of trend of mating groove 100.
After extension board 201 is positioned at mating groove 100, when the thickness of extension board 201 selects different values, extension board
201 also can change relative to the state of mating groove 100.Such as, when the thickness of extension board 201 is less, extension board 201 phase
Caving in for mating groove 100, now the area of passage of bus structure is less；When the thickness of extension board 201 is bigger, extension board
201 relative to mating groove 100 evagination, and now the protuberance branch on extension board 201 causes extension board 201 to there is waste of material
Situation.Therefore, in order to, while obtaining bigger area of passage, reduce the material usage of extension board 201, extension board can be made
Deviating from the surface of mating groove 100 and the bottom surface flush of busbar 10 on 201, the bottom surface of busbar 10 refers to offer mating groove
The surface of 100.
The embodiment of the present application also provides for a kind of battery, and this battery includes the knot that confluxes described by any of the above-described technical scheme
Structure.
The foregoing is only the preferred embodiment of the application, be not limited to the application, for the skill of this area
For art personnel, the application can have various modifications and variations.All within spirit herein and principle, that is made any repaiies
Change, equivalent, improvement etc., within should be included in the protection domain of the application.
