It should be noted that, in the present embodiment, conducting strip 62 is connected with conduction head 12 or external conductive casing 14 end 144 ultrasonic spot weldings of battery core 1, but the utility model is not construed as limiting, and also can take other electrical connection form.
Embodiment 3
As Figure 8-9, power brick, comprises the housing 8 of sealing, is located at the electrode terminal 86 on housing 8, and is contained in embodiment 2 battery components 6 in housing 8.
Concrete, housing 8 comprises the case shape body 82 of an end opening, and the case lid 84 that can be sealed and matched with openend.More specifically, body 82 upper end open, arrange case lid 84.Each battery core 1 axis of battery component 6 is vertically contained in housing 8, between battery component 6 and body 82, is provided with damping device, puts on the impact on battery component 6 for buffer battery bag while bumping.Damping device is specially crash roll 9, and pad is located at battery component 6 bottoms.
The sidewall of body 82 is provided with the convex tendon 822 of vertical extension, puts into the battery component 6 of housing 8, and the depression forming between adjacent two insulating coatings 2 of its periphery can coordinate with convex tendon 822, limits the horizontal level of battery component 6, prevents from rocking.Especially the profile that is applicable to insulating coating 2 is columned situation.And the convex tendons 822 that circumferentially arrange of body 82 with whole above-mentioned depressions one by one at once, effect is better.Crash roll 9 shapes can be consistent with battery component 6 cross sectional shapes, ensures vibration-isolating effect, and meanwhile, the recess 92 of outer rim also can coordinate with convex tendon 822, avoids rocking.
When assembling, successively crash roll 9 and battery component 6 are inserted to body 82, last wire connects and encapsulation.
Although in embodiment 1-3, battery core protective sleeve 4 is made up of two insulating coatings 2, the utility model is not construed as limiting.
Battery core protective sleeve 4 can only have an insulating coating 2, when use, prepares multiple independently insulating coatings 2, and battery core 1 is packed into after each insulating coating 2, connects each insulating coating 2 and each battery core 1 of connecting can form battery component 6 and uses by conducting strip 62.When independently insulating coating 2 fits together, can avoid equally the external conductive casing 14 of adjacent battery core 1 to contact in side direction, and conducting strip 62 conductings are with a conduction head 12 of battery core 1 and the flange 142 of external conductive casing 14.In battery component 6, the quantity that insulating coating 2 is set is even number, can adapt to common needs, for example NiCd power brick, MH power brick, Lion power brick.
Battery core protective sleeve 4 also can comprise more than two insulating coating 2.If insulating coating 2 quantity are even number in battery core protective sleeve 4, in battery core protective sleeve 4, just in time can be divided into the insulating coating 2 of integer group, two insulating coatings, 2 heads 22 are on the same group towards the opposite.In the time that the multiple battery core protective sleeves 4 of assembling become battery component 6, insulating coating 2 quantity in battery component 6 are also even number just.If insulating coating 2 quantity are odd number in battery core protective sleeve 4, there is an independent insulating coating 2, two one group of all the other insulating coating.In the time that the multiple battery core protective sleeves 4 of assembling become battery component 6; because insulating coating 2 sums in battery component 6 are required to be even number; and any one end of battery component 6; conduction head 12 quantity of battery core 1 equal external conductive casing 14 end 144 quantity, and therefore in every two battery core protective sleeves 4, an independent insulating coating 2 can fit in head 22 one group of insulating coating 2 towards the opposite just separately.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and distortion, these improvement and distortion also should be considered as protection range of the present utility model.
