Embodiment is not intended to limit the utility model just for the sake of explaining the utility model.
Please refer to Fig.1 and Fig. 2, a kind of battery cap 100 provided by the utility model, for closing battery (not shown)
One end and as the cathode of battery.The battery cap 100 include main body 10, closing 10 periphery of main body guard circle 20 and
It is respectively arranged on the dished cover 30 and lug 40 at 10 both ends of main body.In the present embodiment, the battery is in cylinder, the master
Body 10, which is adopted, to be made from an insulative material and in cylinder.
Specifically, the main body 10 offers cavity 101, a pair of first relief hole 102 and a pair of second relief hole 103,
The pair of first relief hole 102 is located at the one end of the main body 10 equipped with lug 40 and is connected with the cavity 101, described one
It is located at the one end of the main body 10 equipped with dished cover 30 to the second relief hole 103 and is connected with the cavity 101.The cavity 101
In be equipped with a pair of spool 11 abutted and a pair of resilient members 12, each elastic component 12 and be connected to a spool 11 and the master
Between body 10.In the present embodiment, the elastic component 12 for spring and in compressive state with the pair of spool 11 is mutual
Against.One end that the pair of spool 11 abuts be respectively equipped with 111 other end of conductive part be respectively equipped with one with it is right
Answer the connected sealing 112 of elastic component 12, the conductive part 111 and sealing 112 of each spool 11 and the inner wall of the cavity 101
The pressure release space 113 connected with first relief hole 102 is cooperatively formed, and the pair of spool 11 can be in two pressure release spaces
Move and separate in the direction away from each other under air pressure in 113 so that each pressure release space 113 connects one first and lets out
Press hole 102 and second relief hole 103.In the present embodiment, gap is matched somebody with somebody between the conductive part 111 and the main body 10
Close and separate in order to the pair of spool 11, the pair of first relief hole 102 by the inside of corresponding battery with respectively with two
Pressure release space 113 connects, and will produce substantial amounts of gas when the battery produces exception, and cause the sky in two pressure release spaces 113
Atmospheric pressure steeply rises so that the pair of spool 11 moves and distinguishes two pressure release spaces 113 in the direction away from each other
Connected with corresponding second relief hole 103, so that the air pressure in two pressure release spaces 113 is respectively through corresponding second relief hole
103 are discharged into the outside of battery, to prevent battery explosion.
Further, the dished cover 30 is respectively equipped with one with the lug 40 side close to each other and passes through the main body
10 and the conductive column 50 that is resisted against on two conductive parts 111 of two spools 11, the inside electricity of the lug 40 and corresponding battery
Connect and be electrically connected through two conductive columns 50 and two conductive parts 111 with the dished cover 30, the dished cover 30 and other parts electricity
Connect using the cathode output end as corresponding battery.In the present embodiment, the conductive part 111 of each spool 11 can be conductive and close
Envelope portion 112 insulate so that two conductive columns 50 are electrically connected through two conductive parts 111, and the dished cover 30 is opposite with the main body 10
Side convex to form connecting portion 301 so that the dished cover 30 is electrically connected by the connecting portion 301 with other parts, and make
Obtain the space that can have between the other parts and the main body 10 for second relief hole 103 release gas.It is in addition, described
Dished cover 30 is welded to connect with corresponding conductive column 50 respectively with the lug 40, and the dished cover 30 is welded to connect with the main body.
It is understood that after the pair of spool 11 of gas push that battery produces extremely separates, two conductive parts
111 are electrically connected with two disconnections of conductive columns 50, and the high current so as to prevent battery from producing extremely damages battery or other equipment,
The security performance of battery can be effectively improved；When abnormal battery is let out through corresponding first relief hole 102, pressure release space 113 and second
Hole 103 is pressed to discharge pressure and so that after the pressure of inside battery and extraneous balance, the pair of spool 11 can be in the pair of bullet
Property part 12 under the action of it is mobile to direction close to each other and be electrically connected two conductive parts 111 with two conductive columns 50 so that
The exception battery recovery is normal, so as to not have to replace the battery cap 100 to reduce cost.
Further, the axis of the pair of first relief hole 102 and the pair of second relief hole 103 is positioned at same
It is symmetrical set in plane and along the axis of the main body 10, and the distance between the pair of first relief hole 102 is less than
The distance of the pair of second relief hole 103 so that each pressure release space 113 is when corresponding battery is normal only with corresponding the
One relief hole 102 connection and can after corresponding battery exception and meanwhile with corresponding first relief hole, 102 and second relief hole 103
Connection, so that the battery cap 100, which is closed after a battery, normal use but also to prevent battery abnormal detonation.At this
In embodiment, each second relief hole 103 is sealed close to one end of the dished cover 30 equipped with aluminium foil 1031, can be prevented
Extraneous dust or moisture enter can prevent corresponding battery from electrolyte leakage occurs again.
Further, the guard circle 20 is equipped with circular ring shape and in inner wall the mounting groove coordinated with 10 periphery of main body
201, the guard circle 20 had not only been avoided that the battery cap 100 produced and has damaged bad, but also can close one end of a battery
Play enhancing sealing afterwards.
The utility model is not restricted to described in specification and embodiment, therefore for the personnel of familiar field
For additional advantage and modification is easily achieved, therefore in the universal limited without departing substantially from claim and equivalency range
Spirit and scope in the case of, the utility model is not limited to specific details, representational equipment and shown here as with retouching
The examples shown stated.
