Description
Technical field
The utility model is related to field of lithium, and in particular to a kind of lithium battery cap.
Background technology
For lithium ion battery due to the superior function of itself, use scope is more and more wider.Lithium ion battery is at present
The fields such as automobile, energy-accumulating power station, communication base station are gradually 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 several 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
It when connecing, is required for considering connection resistance and contact performance, it is desirable that there is more preferable and consistency and harmony, each battery core or battery will
It asks connection distance short and symmetrical as possible, contacts 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.
Invention content
To solve deficiency of the prior art, the purpose of this utility model is to provide a kind of lithiums of the special connection mode of band
Anode block.
The technical solution that the utility model is taken is：A kind of screw-type lithium battery cap, including upper cover, upper cover bottom is successively
Gasket and burst disk are installed, burst disk edge wraps up the edge of upper cover upwards, and burst disk bottom is equipped with flow collection sheet, flow collection sheet
Lower section is equipped with sealing ring, and the upper and lower inner bottom surface of sealing ring is wrapped in upper cover edge and flow collection sheet lower edge, flow collection sheet bottom respectively
It is welded with power-off diaphragm and lug, which is characterized in that raise up in the middle part of the upper cover, raised center is equipped with straight down
Endoporus, endoporus inner wall are equipped with screw thread.
Further, the burst disk is gradually 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, the beneficial effects of the utility model are：Connecting hole is threaded on upper lid, it is corresponding
The corresponding threaded post of battery cathode setting can realize the threaded connection of head and the tail, and connection mode is reliable, and conductive performance is good.Simultaneously
The counterbore cooperation funnel-shaped structure of burst disk so that burst disk has enough space-inversions, it is ensured that being capable of effective fragmentation pressure release.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
In figure：Upper cover 1, gasket 2, burst disk 3, endoporus 4, flow collection sheet 5, sealing ring 6 power off diaphragm 7, lug 8.
Specific embodiment
Specific embodiment of the present utility model 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 is sequentially installed with gasket 2 and prevents
Quick-fried 3,1 middle part of upper cover raises up, and raised center is equipped with endoporus 4 straight down, and 4 inner wall of endoporus is equipped with spiral shell
Line.Burst disk 3 is gradually downwardly inclined from edge to centre, and the center of burst disk is downward counterbore, and burst disk 3 is equipped with a circle
Notch, convenient for the explosion pressure release when cell pressure is big.Upper cover 1 is wrapped up after stamping process after digging upwards in 3 edge of burst disk
Edge is handled, it is ensured that the space sealing between burst disk and gasket by embossing.3 bottom of burst disk is equipped with flow collection sheet 5, collection
Gasket is installed between flow 5 and burst disk 3.5 lower section of flow collection sheet is equipped with sealing ring 6, and the upper and lower inner bottom surface of sealing ring 6 wraps respectively
Be wrapped in upper cover edge and flow collection sheet lower edge, will each component be wrapped in together, be coated with glue on sealing ring, form sealing.Collection
Flow bottom is welded with power-off diaphragm 7 and lug 8.
The block is the anode 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 cathode threaded post of a battery is screwed in another battery
The internal control of anode.
