Abstract
The utility model discloses a soft connector of a power battery pack with high reliability. The soft connector of the power battery pack comprises installation parts and a connecting part. The installation parts are located at both ends of the soft connector and provided with installation holes. The connecting part of the soft connector is located between the installation parts. The soft connector is provided with a multi-layer metal foil. Both ends of the multi-layer metal foil are welded in hard integral structure to form the installation parts. The superposing part between both ends of the multi-layer metal foil is provided with a flexible structure with interlayer gaps to form the connecting part. With the adoption of the technical scheme, as the middle connecting part provided by the utility model is in the flexible structure with the interlayer gaps with metal foils, the soft connector is of a certain flexibility naturally. The connecting part is not loosened due to vibration after flexible connection, so that the deficiencies brought by conventional hard connecting manner is well solved, and a highly reliably connecting manner for the power battery pack is provided.
Description
[technical field]
The utility model relates to a kind of connected mode of power battery pack, refers in particular to a kind of flexible link with the high power battery pack of reliability.
[background technology]
Connector of the prior art is widely used in connecting as conduction in the large-current electric device equipment such as various generators, transformer, bus, switch, electrolysis, smelting, these electric equipments normally are in static lower work, so connector is to belong to hard connecting mode.
Electrokinetic cell is to adopt combining form to be applied to electric automobile, the connector that need to use during combination is to be fixed on the pole of battery pack, to adopt the single-layer metal bar as connector at present, this single-layer metal bar is thicker, quality is harder, do not possess flexibility, adopting the connector of the thick type of this hard to be connected between battery and the battery is a kind of hard connection.When electric vehicle drive along with the vibration of car, battery pack also one is followed and is vibrated, easily cause connecting portion loosening, cause the contact point persistent fever because of loose contact between battery pack and the single-layer metal bar after loosening, heating temp surpasses setting, then can aggravate the pole oxidation of battery pack, and oxidation results causes again contact resistance value to rise, impel so again pole to generate heat and further temperature rise, finally cause the power supply difficulty even can produce security incident.
[utility model content]
Technical problem to be solved in the utility model provides a kind of flexible link with power battery pack of high reliability.
For achieving the above object, the utility model provides a kind of flexible link of power battery pack,
A kind of flexible link of power battery pack, comprise installation portion and connecting portion, the installation position is in the two ends of described flexible link, and described installation portion all offers installing hole, the connecting portion of described flexible link is between described installation portion, its improvement is: described flexible link has multilayer metal foil, wherein, described multilayer metal foil two ends all are welded as rigid overall structure to form described installation portion, and the stack section between the multilayer metal foil two ends has the flexible structure in interlayer gap to form described connecting portion.
Above-mentioned connecting portion with interlayer gap is arch.
After connecting portion design with interlayer gap is arch, so that the utlity model has adjustable, by the flexibility of arch connecting portion, can adapt to the mounting distance between the installation portion, can reduce the restriction of range error during installation, have the high characteristics of installation accuracy, and operation for convenience detach.
Above-mentioned multilayer metal foil has 20～30 layers.
Bottom surface at above-mentioned installation portion is equipped with nickel coating.
Behind the design nickel coating, the bottom surface of installation portion has non-oxidizability.
Above-mentioned connecting portion is coated with insulating barrier, and insulating barrier is provided with thermal shrinkage sleeve outward.
After connecting portion arranges insulating barrier, thermal shrinkage sleeve, play certain protective effect and insulating effect.
The utlity model has following advantage and beneficial functional:
The utility model adopts multilayer metal foil, all become the multilayer metal foil two ends whole as installation portion by the welding manner welding, and the middle interconnecting piece of connector this part owing to be that the multi-disc metal forming has the flexible structure in interlayer gap, naturally just has certain flexibility, the flexible link that adopts the technical program to make connects power battery pack just becomes a kind of form that flexibly connects, when producing vibration, can not interact between the electrokinetic cell, be difficult for causing the loosening of connecting portion, solved well the drawback that traditional hard connecting mode brings, for power battery pack provides a kind of highly reliable connected mode.
