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, the connector for battery core series connection, including main body annulus 1, the outer circumference edge of main body annulus 1
Main body annulus 1 is axially arranged multigroup negative pole elastic card claw 4, the inside circumference of main body annulus 1 be also evenly arranged with it is multiple just
Pole flexible connection piece 3, multiple positive pole flexible connection pieces 3 tilt the end face for protruding from main body annulus 1；Main body annulus 1, which is located at, appoints
Flexible contact chip 2 also is radially arranged along main body annulus 1 between meaning two adjacent groups negative pole elastic card claw 4, elastic contact chip 2 tilts
The end face of main body annulus 1 is protruded from, elastic contact chip 2 and negative pole elastic card claw 4 protrude from the same side of main body annulus 1,
Positive pole flexible connection piece 3 protrudes from the another side of main body annulus 1；The main body annulus 1, elastic contact chip 2, positive pole elasticity are even
Contact pin 3 and negative pole elastic card claw 4 are conductor.
The operation principle of the present embodiment is：Battery core negative pole (i.e. battery core shell) is clamped in negative pole elastic card claw 4, will simultaneously
Townhouse is clamped between main body annulus 1 and battery core negative pole and is adjacent to elastic contact chip 2 and contacted, then by positive pole flexible connection piece
3 with battery core positive contact, finally using battery core module assemble necessary to along battery core axial direction pressure, by connector and parallel connection
Row is pressed between battery core the two poles of the earth, completes connection.
The present embodiment connects battery core both positive and negative polarity, and simultaneously townhouse will be clamped on therebetween, realizes stabilization between battery core
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
External force, also allow for dismantling, repair and changing, and there is certain elasticity between connector, it is possible to reduce be connected with multiple battery cores it
Between mutual stress, avoid junction there is gap or mistake and failure of connecting.
In the present embodiment, the negative pole elastic card claw 4 is along snakelike folding of the axial direction of main body annulus 1 through being repeatedly bent to form
Plate.The main purpose of negative pole elastic card claw 4 is then to be used for clamping battery core negative pole, so as to be bent to form snakelike folded plate by secondary, no
Its clamping force to battery core negative pole can only be increased, and also add while flexible and toughness and to be connect with battery core negative pole
Contacting surface is accumulated, and the locating effect to battery core negative pole is also assures that while intensity is improved.
In the present embodiment, the angle of inclination of the elastic contact chip 2 is less than the angle of inclination of positive pole flexible connection piece 3.Bullet
Property contact chip 2 battery core module assembling necessary to along battery core axial direction pressure effect under can with and townhouse easily connect very much
Touch, and positive pole flexible connection piece 3 then needs to ensure that it is contacted all the time with positive pole, therefore, should be larger for the elastic force of positive pole, can
Still ensure that positive pole flexible connection piece 3 is in contact with it in the presence of external force changes, therefore, positive pole flexible connection piece 3
Angle of inclination should be greater than the angle of inclination of elastic contact chip 2, obtains larger elastic force with this and reduces the deformation pair of elastic contact chip 2
Influence caused by it.
In the present embodiment, the main body annulus 1, elastic contact chip 2, positive pole flexible connection piece 3 and negative pole elastic card claw 4
Material is elastic stainless steel.Flexible and corrosion-resistant, the conductive effect of elastic stainless steel, it can use for a long time without failing,
Extend connector 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.
