Abstract
The utility model provides a kind of lithium battery circuit plate, including：Substrate and layers of copper, the layers of copper is attached to the surface of the substrate, and the layers of copper includes the contact area scooped out with the lug position of lithium battery, and the surface of the contact area of the layers of copper leads to overetched mode and forms scraggly rough surface.The utility model can utilize the salient point formed at rough surface to cause slightly to puncture to lug, so as to which conductive contact be better achieved, so as to reduce resistance value and fever, improve loose contact problem, it solves in the prior art because of contact resistance problems of too, solves fever and problem of pressure drop caused by resistance value is excessive.
Description
Technical field
The utility model is related to circuit board manufacturing area, more particularly to a kind of lithium battery circuit plate.
Background technology
At present, the part that lithium battery circuit plate is contacted with lug is using being smooth plane, therefore, if surface occurs gently
It is micro- it is dirty if, can cause to contact the problems such as bad, resistance value is big, fever, also can make lithium battery in lithium battery charging and discharging
Road plate and lug loose contact, caused by a series of problems.
Utility model content
The utility model provides a kind of lithium battery circuit plate, is connect with solving lithium battery circuit plate in the prior art with lug
Touch the problem of bad.
To solve the above problems, the one side as the utility model, provides a kind of lithium battery circuit plate, including：
Substrate and layers of copper, the layers of copper is attached to the surface of the substrate, and the layers of copper includes scooping out with the lug position of lithium battery
Contact area, the surface of the contact area of the layers of copper leads to overetched mode and forms scraggly rough surface.
Preferably, the layers of copper includes the first layers of copper, the second layers of copper, the 3rd layers of copper and the 4th layers of copper, first layers of copper
It is L-shaped, the L-shaped include be mutually connected vertically first while and when second, first side and the second skirt are into a notch
Region, second layers of copper are arranged on the end on first side, and the 3rd layers of copper is arranged in parallel with the 4th layers of copper, and
3rd layers of copper and the 4th layers of copper are located in the gap regions, first layers of copper, the second layers of copper, the 3rd layers of copper and the
Four layers of copper are respectively formed there are one the contact area.
Preferably, the height of the salient point on the rough surface is 0.01-0.5mm.
Preferably, the height of the salient point on the rough surface is 0.01-0.35mm.
The utility model can utilize the salient point formed at rough surface to cause slightly to puncture to lug, be led so as to be better achieved
Electrical contact, so as to reduce resistance value and fever, improves loose contact problem, solves and asked in the prior art because contact resistance is excessive
Topic solves fever and problem of pressure drop caused by resistance value is excessive.
Description of the drawings
Fig. 1 schematically shows the structure diagram of the utility model.
Reference numeral in figure：1st, substrate；2nd, contact area；3rd, the first layers of copper；4th, the second layers of copper；5th, the 3rd layers of copper；6th,
Four layers of copper.
Specific embodiment
The embodiment of the utility model is described in detail below in conjunction with attached drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
The one side of the utility model provides a kind of lithium battery circuit plate, including：Substrate 1 and layers of copper, the layers of copper
The surface of the substrate 1 is attached to, and the layers of copper includes the contact area 2 scooped out with the lug position of lithium battery, the copper
The surface of the contact area 2 of layer leads to overetched mode and forms scraggly rough surface.
By adopting the above-described technical solution, the utility model can utilize the salient point formed at rough surface to be caused to lug gently
Aculea is broken, and so as to which conductive contact be better achieved, so as to reduce resistance value and fever, improves loose contact problem, is solved existing
Have in technology because of contact resistance problems of too, solve fever and problem of pressure drop caused by resistance value is excessive.
Preferably, the layers of copper include the first layers of copper 3, the second layers of copper 4, the 3rd layers of copper 5 and the 4th layers of copper 6, described first

Gap regions, second layers of copper are arranged on the end on first side, and the 3rd layers of copper 5 is parallel with the 4th layers of copper 6
Set, and the 3rd layers of copper 5 and the 4th layers of copper 6 are located in the gap regions, first layers of copper 3, the second layers of copper 4,
3rd layers of copper 5 and the 4th layers of copper 6 are respectively formed there are one the contact area 2.
Preferably, the height of the salient point on the rough surface is 0.01-0.5mm.
Preferably, the height of the salient point on the rough surface is 0.01-0.35mm.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modifications, equivalent replacements and improvements are made should be included within the scope of protection of this utility model.
