For this purpose, the utility model uses following technical scheme:
A kind of lithium battery cap component, successively includes orifice plate, insulated ring, explosion rupture disk, top cover and sealing ring, and feature exists
In, the explosion rupture disk it is equipped with the first boss towards the side of orifice plate, the orifice plate is equipped with to fit with the first boss
Second boss, the first boss and the second boss are using welded connecting.
Preferably, the first boss is formed in the surface of the explosion rupture disk, be from the explosion rupture disk edge gradually in
The table top of certain area obtained from the protuberance deformation of mandrel line near zone.
Preferably, the surface area of the first boss is greater than or equal to the surface area of the second boss.
Preferably, the orifice plate is equipped with buckle, and the buckle is for latching the orifice plate and the insulated ring.
Preferably, the face of the explosion rupture disk towards the orifice plate side is equipped with explosion-proof groove.
Preferably, the orifice plate helps broken string equipped with explosion-proof.
Preferably, the explosion-proof explosion-proof pressure for helping broken string is less than the explosion-proof pressure of the explosion-proof groove.
Preferably, the explosion-proof groove and explosion-proof help are broken on respective depth direction in inverted trapezoidal structure.
Preferably, welded connecting is taken between the top cover and the explosion rupture disk.
Preferably, laser welding or ultrasonic bonding is taken between the first boss and the second boss.
The utility model has the following beneficial effects:
1, a kind of lithium battery cap component of the utility model directly can be pasted closely to reach explosion rupture disk and orifice plate
It closes, explosion rupture disk swells a first boss upwards, and the down-set second boss of orifice plate, both makes to contact in this way, then in laser
It welds the side of cap assembly under welding or ultrasonic bonding to lead admittedly.It not only ensure that inside does not generate hot air, together
When welding surface it is relatively thin, woth no need to wlding, welding efficiency is high, and temperature is low, the advantages that reducing energy consumption.
2, a kind of lithium battery cap component of the utility model, since top cover and explosion rupture disk use directly by top cover towards anti-

Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
Embodiment 1
As shown in Figures 1 to 4, one of the present embodiment lithium battery cap component successively includes orifice plate 1, insulated ring 2, prevents
Quick-fried 3, top cover 4 and sealing ring 5, explosion rupture disk 3 are equipped with the first boss 31 towards the side of orifice plate 1, orifice plate 1 be equipped with it is first convex
The second boss 11 that platform 31 fits, first boss 31 and second boss 11 are using welded connecting.That is, in order to reach two
Person can directly fit closely, one first boss 31 of upward protuberance of explosion rupture disk 3, and the down-set second boss 11 of orifice plate 1, in this way
The two is contacted, then welds under laser welding or ultrasonic bonding the side of cap assembly and leads admittedly.This ensure that interior
Portion does not generate hot air, while welding surface is relatively thin, and woth no need to wlding, welding efficiency is high, and temperature is low, reduces energy consumption etc.
Advantage.Further, first boss 31 is formed in the surface of explosion rupture disk 3, be from 3 edge of explosion rupture disk gradually near central axis
The platform of certain area obtained from the protuberance deformation of region.Platform it is generally circular, it is identical as 11 shape of second boss,
