Abstract
The utility model relates to a soft copper strips lithium battery connection piece of high stability, including the connection piece body, the connection piece body adopts soft copper strips, soft copper strips is provided with a plurality of bending and a plurality of disconnected poor structure, the outer surface coating of soft copper strips has polyimide film, polyimide film passes through the high temperature pressfitting with soft copper strips and pastes mutually, the connection piece body exposes to be provided with at the surface of outer part and protects the copper layer. The beneficial effects of the utility model are that increase being widely used of copper battery connection piece, adopt soft copper strips easily to process, adopt polyimide film, protect the setting on copper layer, protective bonding piece body, prevent its by the oxidation, electric conductivity is good, long service life.
Description
Technical field
This utility model is related to connection sheet field, the soft copper strips lithium battery connection sheet of more particularly, to a kind of high stability.
Background technology
Existing copper cell connector is made up of the copper material of general hardness, and copper material is between battery and battery
One connection.Because the more complicated product of hardness reason processing technique is difficult to, in use can be because of surrounding
Vibrations, displacement or temperature is excessively high causes interruption of service；And copper surface exposure is extremely oxidized easily in atmosphere, copper oxide is
Belong to quasiconductor, electric conductivity is poor.Its conductive stability and service life are had a great impact.
Utility model content
For overcoming disadvantages mentioned above, the purpose of this utility model is to provide a kind of easy to process, good conductivity, service life
Long high stability soft copper strips lithium battery connection sheet.
In order to reach object above, the technical solution adopted in the utility model is：A kind of high stability soft copper strips lithium electricity
Pond connection sheet, including connection sheet body, described connection sheet body adopts soft copper strips, and described soft copper strips is provided with multiple bendings
And multiple break difference structure, described soft copper strips outer surface is enclosed with Kapton, described Kapton with soft
Copper strips is affixed by high-temperature laminating, and the outer surface of the exposed part of described connection sheet body is provided with shield layers of copper.This practicality
New beneficial effect is to replace hard copper to make the connection sheet carrying bending, offset using soft state copper strips, make high-current equipment
Between be conductively connected more convenient, reliable, safety, protect each associate device not affected by external force, solve the copper of general hardness
Electrolyte cell connection sheet hardness is higher, and processing technique is more complicated, the unmanageable problem of product；The connection sheet being made up of soft copper strips
It is PI film that the outer surface of body is enclosed with Kapton, can within the temperature range of -269 DEG C ~ 280 DEG C life-time service, 20
DEG C when tensile strength be 200MPa, make copper strips lithium battery connection sheet relatively stable in temperature range and frequency range, by part
One layer of shield layers of copper is provided with exposed connection sheet body so as to junction point will not be oxidized, thus ensureing that copper strips connects
The conductive stability of piece and service life, the copper cell connector solving hard easily aoxidizes in atmosphere, significantly contracts
The short problem of the service life of cell connector；Structure can be processed by multiple bendings and break difference structure more complicated
, diversified cell connector, be easy to Mulit-point Connection, be more convenient to widely use in all kinds of battery bags.
Preferably, the hardness of described soft copper strips is 45HV ~ 90HV.The softness of the soft copper strips of this hardness range is more suitable
Preferably.
Preferably, the thickness of described Kapton is 0.05mm.
Brief description
Fig. 1 is the structural representation of the present embodiment.
In figure：1- connection sheet body；2- connection sheet body；3- protects layers of copper；4- bending.
Specific embodiment
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, thus make apparent clear and definite to protection domain of the present utility model
Define.
Referring to shown in accompanying drawing 1, a kind of high stability soft copper strips lithium battery connection sheet of the present embodiment, including connection sheet basis
Body 1, connection sheet body 1 adopts soft copper strips, and wherein, the hardness of soft copper strips is 45HV ~ 90HV, the soft copper of this hardness range
Band is easier to be provided with multiple bendings 4 and multiple break difference structure, by multiple bending 4 structures, can process structure more multiple
Miscellaneous, diversified cell connector；It is easy to Mulit-point Connection, be more convenient to widely use in all kinds of battery bags, outside soft copper strips
It is coated with Kapton 2, Kapton 2 will not be oxidized in protection connection sheet body 1, can also prevent simultaneously
Short circuit between battery during only using, the thickness of Kapton 2 is 0.05mm, Kapton 2 and soft copper strips
Both are close to press operation pressing soon by high temperature, and the outer surface of the exposed part of connection sheet body 1 is provided with shield layers of copper 3.
Replace hard copper to make the connection sheet carrying bending 4, offset using soft state copper strips, make being conductively connected more between high-current equipment
Convenient, reliable, safety, protect each associate device not affected by external force；The outer surface of the connection sheet body 1 being made up of soft copper strips
Being enclosed with Kapton 2 is PI film, can within the temperature range of -269 DEG C ~ 280 DEG C life-time service, tensile strength when 20 DEG C
For 200MPa, make the lithium battery connection sheet of soft copper strips material relatively stable in temperature range and frequency range；To be partly naked
One layer of shield layers of copper 3 is provided with the connection sheet body 1 exposing outside so as to junction point will not be oxidized, connection that can be more stable
Between two batteries, thus ensureing the conductive stability of copper strips connection sheet and service life.
Embodiment of above is only that technology design of the present utility model and feature are described, its object is to allow and is familiar with this skill
The people of art understands that content of the present utility model is simultaneously carried out, and can not limit protection domain of the present utility model with this, all
The equivalence changes done according to this utility model spirit or modification, all should cover in protection domain of the present utility model.
