Description
Technical field
Battery core connector is the utility model is related to, belongs to battery core cell art, more specifically, the utility model relates to
A kind of and contact battery core connecting spring piece.
Background technology
The application of new energy be current country vigorously advocate with popularization and application project, in new-energy automobile, battery core is it
The elementary cell of the energy, it is in new-energy automobile production that thousands of independent battery cores are combined into several or ten several battery core modules
Indispensable process.
Need to be serially connected to form path between battery core in battery core module, the connected mode of current domestic similar-type products
For：It will be welded as a whole with Contact welding or Laser Welding for totally three for the contact chip of connection and battery core positive pole and townhouse, generally needed
To weld twice.Welding sequence not only needs special welding equipment and special tooling, and time-consuming, and cost is high, efficiency is low,
It is also extremely inconvenient that subsequent maintenance is changed, while needs to be molded the guiding for being several times as much as battery core quantity on fixed plastic frame
Groove, there is direction requirement when spring leaf is installed, the process that screening direction must be provided with.
Utility model content
Based on above technical problem, the utility model provides a kind of contact battery core connecting spring piece, and the spring leaf can
Battery core both positive and negative polarity is directly connected to, cost and process increase, influence are caused so as to solve conventional battery core series winding needs welding
The technical problem of battery core joint efficiency.
To solve above technical problem, the technical solution adopted in the utility model is as follows：
Contact battery core connecting spring piece, including main body annulus, main body annulus lateral surface are circumferentially evenly arranged with some
Individual negative pole elastic contact chip, the main body annulus medial surface is circumferentially evenly arranged with several positive pole flexible connection pieces, described
Negative pole elastic contact chip and positive pole flexible connection piece respectively tilt the both sides end face for protruding from main body annulus, and the main body is justified
Ring, negative pole elastic contact chip and positive pole flexible connection piece are conductor.
Preferably, the angle of inclination of the negative pole elastic contact chip is less than the angle of inclination of positive pole flexible connection piece.
Preferably, the main body annulus, negative pole elastic contact chip and the equal material of positive pole flexible connection piece be elasticity not
Become rusty steel.
In summary, by adopting the above-described technical solution, the beneficial effects of the utility model are：The utility model structure
Simply, the connection battery core both positive and negative polarity that can stablize, and row pressure in parallel is tight between, so as to which multiple battery cores be connected, save
Battery core welding sequence is removed, not only connection is easy, time saving and energy saving efficiency high, and subsequently also detachable when changing or repairing battery core
It is convenient.

Fig. 1 is front view of the present utility model；
Fig. 2 is side view of the present utility model；
Fig. 3 is top view of the present utility model；
Fig. 4 is dimensional structure diagram of the present utility model；
Marked in figure：1st, negative pole elastic contact chip；2nd, positive pole flexible connection piece；3rd, main body annulus.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.Embodiment of the present utility model includes but unlimited
In the following example.
As Figure 1-Figure 4, contact battery core connecting spring piece, including main body annulus 3, the lateral surface of main body annulus 3 is in circle
It is evenly arranged with several negative pole elastic contact chips 1 week, the medial surface of main body annulus 3 is circumferentially being evenly arranged with several just
Pole flexible connection piece 2, the negative pole elastic contact chip 1 and positive pole flexible connection piece 2, which respectively tilt, protrudes from main body annulus 3
Both sides end face, and the main body annulus 3, negative pole elastic contact chip 1 and positive pole flexible connection piece 2 are conductor.
The present embodiment is in use, battery core connecting spring piece is arranged between battery core positive pole and negative pole, negative pole Elastic Contact
Piece 1 and battery core cathode contact, positive pole flexible connection piece 2 and battery core positive contact, by row pressure in parallel negative pole elastic contact chip 1 with
Between battery core negative pole, contact is kept, along the pressure of battery core axial direction necessary to finally being assembled using battery core module, battery core is connected
Connect spring leaf and row in parallel is pressed between battery core the two poles of the earth, complete connection.
The present embodiment connects battery core both positive and negative polarity, and, realizes stabilization between battery core by row clamping in parallel between
Efficient series connection, it is firm without welding again, process and cost have been saved, has reduced connection difficulty and efficiency, meanwhile, the activity is even
The mode connect can be achieved to compress connection necessary to assembling by battery core module along the pressure of battery core axial direction, without setting again
External force, also allow for dismantling, repair and changing, and there is certain elasticity between connector, negative pole elastic contact chip 1 and positive pole elasticity
The end in stress of connection sheet 2 is then parallel with contact surface, ensures that contact is stable, can also reduce and be connected between multiple battery cores
Mutual stress, avoid junction there is gap or mistake and failure of connecting.
In the present embodiment, the angle of inclination of the negative pole elastic contact chip 1 is less than the inclination angle of positive pole flexible connection piece 2
Degree.Can be with simultaneously townhouse very under pressure effect of the negative pole elastic contact chip 1 necessary to battery core module assembling along battery core axial direction
Easily contact, and positive pole flexible connection piece 2 then needs to ensure that it is contacted all the time with positive pole, therefore, positive pole flexible connection piece 2
Angle of inclination should be greater than the angle of inclination of negative pole elastic contact chip 1, because the quantity of negative pole elastic contact chip 1 is more, so often
The elastic force that individual negative pole elastic contact chip 1 is shared is smaller, and can reduce the deformation of elastic contact chip 2 influences to caused by it, is always ensured that
The two is contacted with battery core both positive and negative polarity.
In the present embodiment, the main body annulus 3, negative pole elastic contact chip 1 and the equal material of positive pole flexible connection piece 2 are
Elastic stainless steel.Flexible and corrosion-resistant, the conductive effect of elastic stainless steel, it can for a long time use without failing, extend connection
Part service life.
It is embodiment of the present utility model as described above.Described previously is each preferred embodiment of the present utility model,
Preferred embodiment in each preferred embodiment if not obvious contradictory or premised on a certain preferred embodiment,
Each preferred embodiment arbitrarily stack combinations can use, the design parameter in the embodiment and embodiment be only for
The utility model verification process of clear statement utility model people, and be not used to limit scope of patent protection of the present utility model,
Scope of patent protection of the present utility model is still defined by its claims, every with specification of the present utility model and attached
The equivalent structure change that figure content is made, similarly should be included in the scope of protection of the utility model.
