Defect:
1) electric connection mode connection is unreliable, and contact resistance is big；
2) electric connection mode is high to the manufacturing technique requirent of switching copper bar, the quality requirement height that presses of self-clinching nut；
3) electric connection mode group efficiency is low and grouped aspect is single.
Though there is patent No. 201721591256.X to disclose a kind of direct-connected structure of battery core and its battery pack, battery core is equipped with electricity
Pole, direct-connected structure include copper bar and connector, and the copper bar is L shape, and the bottom surface of the copper bar is welded on the electrode, the copper
The facade of row is equipped with fixation hole, and the connection sheet is strip sheet metal part, and the both ends of the connection sheet are equipped with fixation hole,
Two fixation holes of the connector are respectively aligned to the fixation hole for the copper bar that two need to be electrically connected, by clamping screw through solid
Determine hole and connects connector with copper bar.L-type connecting copper bar is welded in battery core by the utility model by simple frock clamp,
Then by switching copper bar by adjacent battery core bolt locking together tightly.Above-mentioned connection type has group efficiency height, can
By formed it is a variety of it is series-parallel in the form of, but its structure or not easy enough, and by increasing L-type connecting copper bar and being welded to electricity
On core, it is easy failure welding, inconvenient.
Utility model content
Therefore, for above-mentioned problem, the utility model proposes a kind of connection types to have group efficiency high, can be formed more
The series-parallel form of kind, and do not need by too many external tool or accessory, direct-connected lithium battery easy to operate.
To achieve the above object, the utility model uses following technical scheme: a kind of direct-connected lithium battery, including battery
Shell and the lithium battery inside battery case, the battery case include cabinet and pass through the lid of ultrasonic wave hot-melt adhesive paste with cabinet
Body, the lithium battery are equipped with the conducting wire for being separately connected its anode, cathode, and the lid both ends set that there are two for two conducting wires point
It is not pierced by the through-hole of battery case, the outer surface both ends of the lid are respectively equipped with the groove for placing conducting wire, each groove
One end be connected to respectively with corresponding through-hole, the holding that the two sides in each groove portion in the inner are equipped with holding conducting wire is convex
It rises.
It further improves, the lid is recessed downwards respectively at side of the groove far from through-hole one end and forms notch, institute
The bottom for stating notch is higher than the bottom of groove.
It further improves, the lid is equipped with handle, and the handle is that surface is smooth in the two sides in middle position
Excessive waveform curved surface.
It further improves, the handle is made of plastic material, and both ends are detachably connected with lid.
By using preceding solution, the beneficial effects of the utility model are: the utility model lithium battery and lithium battery
Or be powered between product and be directly attached by conducting wire, with existing by passing through again after connecting column is arranged on lithium battery
Self-clinching nut, switching copper bar or conducting wire mating connection are compared, and switching copper bar and self-clinching nut is omitted, reduce the manufacturing at
This, and connection type has group efficiency high, can form a variety of series-parallel forms, and do not need by too many external tool or
Accessory, simple element are easy to operate；Further, it by the way that groove holding conducting wire is arranged, is stored convenient for conducting wire；It further, is handle
The configuration design waveform curved surface of suitable grip, carries it conveniently, and easy for assembly with shell, at the same make shell with
Exquisite beautiful shape.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the partial cross-sectional view of the utility model lid；
Fig. 3 is the structural schematic diagram of the utility model handle.
