Description
Technical field
The present invention relates to field of lithium, and in particular to a kind of lithium battery cap.
Background technology
Lithium ion battery is more and more wider due to the superior function of itself, its use scope.Lithium ion battery is at present
The fields such as automobile, energy-accumulating power station, communication base station are progressively expanded to from small mobile products, the lithium ion battery that these fields use
There is large capacity, high current charge-discharge.And the lithium battery for being used for power is led to by some battery cores and/or single battery
Cross corresponding attachment device be attached it is in parallel form a complete power supply, in multiple battery cores or single battery mutually simultaneously
When connecing, it is required for considering connection resistance and contact performance, it is desirable to there is more preferable and uniformity and harmony, each battery core or battery will
Ask connection distance as far as possible short and symmetrical, contact reliably, reduce attachment device as far as possible in the case where ensuring load capacity
Volume, to increase the effective volume of lithium battery ratio.
The content of the invention
To solve deficiency of the prior art, it is an object of the invention to provide a kind of lithium battery of the special connection mode of band
Cathode block.
The technical solution that the present invention takes is：A kind of screw-type lithium battery cap, including upper cover, upper cover bottom are installed successively
There are gasket and burst disk, burst disk edge wraps up the edge of upper cover upwards, and burst disk bottom is provided with flow collection sheet, flow collection sheet lower section
Equipped with sealing ring, the upper and lower inner bottom surface of sealing ring is wrapped in upper cover edge and flow collection sheet lower edge, the welding of flow collection sheet bottom respectively
There is power-off diaphragm and lug, it is characterised in that raise up in the middle part of the upper cover, raised center is equipped with straight down interior
Hole, endoporus inner wall are equipped with screw thread.
Further, the burst disk is progressively tilted down from edge to centre, and the center of burst disk is downward counterbore,
Burst disk is equipped with a circle notch.
Further, gasket is installed between flow collection sheet and burst disk.
After taking above technical scheme, beneficial effects of the present invention are：Connecting hole, corresponding battery are threaded on upper lid
Anode sets corresponding threaded post to realize the threaded connection of head and the tail, and connection mode is reliable, and conductive performance is good.It is explosion-proof at the same time
The counterbore of piece coordinates funnel-shaped structure so that burst disk has enough space-inversions, it is ensured that being capable of effective fragmentation pressure release.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention；
In figure：Upper cover 1, gasket 2, burst disk 3, endoporus 4, flow collection sheet 5, sealing ring 6, powers off diaphragm 7, lug 8.
Embodiment
The embodiment of the present invention is further described below in conjunction with attached drawing：
As shown in the figure, a kind of screw-type lithium battery cap, including upper cover 1,1 bottom of upper cover are sequentially installed with gasket 2 and burst disk
3, the middle part of upper cover 1 raises up, and raised center is equipped with endoporus 4 straight down, and 4 inner wall of endoporus is equipped with screw thread.It is anti-
Progressively it is downwardly inclined from edge to centre for quick-fried 3, the center of burst disk is downward counterbore, and burst disk 3 is equipped with a circle notch,
Easy to the explosion pressure release when cell pressure is big.3 edge of burst disk wraps up the edge of upper cover 1 after stamping process after digging upwards,
Handled by embossing, it is ensured that the space sealing between burst disk and gasket.3 bottom of burst disk is provided with flow collection sheet 5, flow collection sheet 5
Gasket is installed between burst disk 3.The lower section of flow collection sheet 5 is equipped with sealing ring 6, and the upper and lower inner bottom surface of sealing ring 6 is wrapped in respectively
Lid edge and flow collection sheet lower edge, will each component be wrapped in together, scribble glue on sealing ring, form sealing.Flow collection sheet bottom
Portion is welded with power-off diaphragm 7 and lug 8.
The block is the cathode of battery, to coordinate the capping structure, in the housing bottom welding of battery cathode or one
Threaded post is molded, after assembling as battery, when two batteries connect, as long as the anode threaded post of a battery is screwed in another battery
The internal control of cathode.
