Abstract
The utility model provides an insulation cover for a battery module group, which comprises a base plate; a plurality of circular sleeves capable of sleeving one end of each battery body is arranged on the base plate; and a plurality of rectangular holes corresponding to spot welding areas of the electrode surfaces of the batteries are further formed on the base plate. The walls of the circular sleeves are different, and the walls corresponding to a tin-soldering solder joint area extracted by a nickel sheet are higher.
Description
[technical field]
The utility model relates to a kind of insulating case, particularly a kind of battery modules insulating case.
[background technology]
Battery modules is widely used as the indispensable power supply of a lot of electronic products, sees also Fig. 1, shown in Figure 2, and battery modules is all combined by 1 connection of multiple batteries body usually, and battery modules also needs to electrically connect with other assembly.Nickel sheet 2 generally includes banded regions 20, exit 21 for this reason, and wherein banded regions 20 is used for the respective electrode that spot welding connects corresponding battery, the soldering solder joint that exit 21 works are connected with other assembly.Damage the battery outer surface during for insulation between the consideration electrode and solder joint welding, often after reserving the zone of spot welding nickel sheet, electrode surface covers insulating paper 30, and on the soldering solder joint underlay of drawing insulating paper 31, for preventing that insulating paper 31 dislocation causing nickel sheet 2 from touching with the cell body residing electrode misconnection in surface, also the exit 22 through the nickel sheet 2 of being everlasting puts insulating sleeve 4.Cell body 1 joint number that has when battery modules and solder joint will produce a large amount of workloads for a long time, cause inefficiency, and the displacement of insulating paper 31, the aging potential safety hazard that easily produces.
[summary of the invention]
The purpose of this utility model is to provide a kind of battery modules insulating case, too much adopts the way of insulating paper when replacing the module of assembled battery in the past, reduces workload, and improves reliability.
In order to achieve the above object, the utility model battery modules comprises base plate with insulating case, base plate is provided with several circular sleeves that can corresponding entangle each cell body one end, and on the base plate of battery modules, be provided with the slot in some counter electrode surface point welding zones territory with insulating case, described circular sleeve barrel height differs, and is higher in the soldering spot area of the exit of corresponding nickel sheet.So during the assembled battery module as long as correspondence puts battery modules and can directly carry out spot welding, soldering with insulating case, save the extensive work amount, reduce cost.
Compared to prior art, battery modules has reduced workload with the use of insulating case, improves the reliability of insulation.

Fig. 1 is existing battery modules insulation system schematic diagram.
Fig. 2 is existing battery modules insulation general assembly drawing.
Fig. 3 is the utility model battery modules insulating case structural representation.
Fig. 4 is the utility model battery modules insulating case general assembly drawing.
[embodiment]
The utility model battery modules comprises base plate with insulating case, and base plate is provided with several can corresponding entangle the circular sleeve of each cell body one end, and is provided with some counter electrode surface point welding zones territory slot on the base plate of battery modules with insulating case.
Please refer to Fig. 3, shown in Figure 4, the utility model battery modules insulating case one preferred embodiment theory structure schematic diagram and general assembly drawing.In the present embodiment, described battery modules comprises two batteries bodies 1, the utility model battery modules comprises base plate 50 with insulating case 5,50 are provided with two and can corresponding entangle the circular sleeve 51 of each cell body 1 one end on the base plate, and are provided with two counter electrode surface point welding zone territory slots 52 on the base plate 50 of battery modules with insulating case 5.Circular sleeve 51 barrels 510 highly differ as described in Figure 1 in the present embodiment, regional higher at the soldering solder joint of corresponding nickel sheet 2 exits 21.So during the assembled battery module as long as correspondence puts battery modules and can directly carry out spot welding, soldering with insulating case 5, saving extensive work amount reduces cost.
Compared to prior art, the use of insulation cover for battery module group has reduced workload, has improved the reliability of insulation.
