SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: in order to solve traditional lithium cell structure, the utmost point ear by pure aluminium preparation adopts the sheet structure usually, the thickness is unanimous basically, with utmost point ear welding on explosion-proof aluminum sheet, and because the lithium cell inner space is effective in the installation, because partly welding of utmost point ear is on explosion-proof aluminum sheet, and the fusing part of utmost point ear then sets up perpendicularly in the steel cap inner chamber, the space is more effective between utmost point ear and the explosion-proof aluminum sheet, it is more difficult to make utmost point ear welding, the welding degree of difficulty of utmost point ear has been improved, the staff's operation of being not convenient for, the problem of work efficiency has also just also been reduced, explosion-proof battery is now provided.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an explosion-proof battery, includes box hat, explosion-proof aluminum sheet, steel hat and sealing washer, the steel hat sets up on explosion-proof aluminum sheet, explosion-proof aluminum sheet sets up on the box hat, the sealing washer sets up between explosion-proof aluminum sheet and box hat, still includes utmost point ear and insulating layer, utmost point ear includes fixed part and fusing portion, fixed part fixed connection is on explosion-proof aluminum sheet, the fixed part is semi-closed loop configuration, fusing portion sets up inboard at the loop configuration of fixed part, fusing portion outwards extends has the stabilizer blade, the one end and the fixed part of stabilizer blade are connected, the stabilizer blade can burn out and realize and break off between the fixed part when meetting the heavy current and flow, the insulating layer sets up on fixed part and fusing portion, utmost point ear is located explosion-proof aluminum sheet and keeps away from the one end of steel hat, utmost point ear is located the box hat. Through setting up fusing part in semi-enclosed annular structure's fixed part, only need weld between fixed part and the explosion-proof aluminum sheet like this, reduced staff's the operation degree of difficulty like this.
Further, the pole lug, the insulating layer and the steel cap are sequentially overlapped.
The utility model has the advantages that: the utility model discloses explosion-proof battery is when using, through setting up fusing part in semi-enclosed annular structure's fixed part, only need to weld between fixed part and the explosion-proof aluminum sheet like this, staff's the operation degree of difficulty has been reduced like this, among the traditional lithium cell structure has been avoided, the utmost point ear by pure aluminium preparation adopts sheet structure usually, the thickness is unanimous basically, with utmost point ear welding on the explosion-proof aluminum sheet, and because the lithium cell inner space is effective in the installation, because partly welding of utmost point ear is on the explosion-proof aluminum sheet, and the fusing part of utmost point ear then sets up perpendicularly in the steel cap inner chamber, the space is more effective between utmost point ear and the explosion-proof aluminum sheet, make utmost point ear welding more difficult, the welding degree of difficulty of utmost point ear has been improved, be not convenient for staff's operation, just.

Fig. 1 is a front view of the present invention;
fig. 2 is a plan view of a tab in the present invention;
fig. 3 is a partially enlarged view of a in fig. 1.
In the figure: 1. the steel shell, 2, explosion-proof aluminum sheet, 3, steel cap, 4, sealing washer, 5, utmost point ear, 6, insulating layer, 7, fixed part, 8, fusing portion, 9, stabilizer blade.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
Examples
As shown in fig. 1-3, an explosion-proof battery comprises a steel shell 1, an explosion-proof aluminum sheet 2, a steel cap 3 and a sealing ring 4, wherein the steel cap 3 is arranged on the explosion-proof aluminum sheet 2, the explosion-proof aluminum sheet 2 is arranged on the steel shell 1, the sealing ring 4 is arranged between the explosion-proof aluminum sheet 2 and the steel shell 1, the explosion-proof battery further comprises a tab 5 and an insulating layer 6, the tab 5 comprises a fixing portion 7 and a fusing portion 8, the fixing portion 7 is fixedly connected to the explosion-proof aluminum sheet 2, the fixing portion 7 is of a semi-closed annular structure, the fusing portion 8 is arranged on the inner side of the annular structure of the fixing portion 7, the fusing portion 8 extends outwards to form a supporting leg 9, one end of the supporting leg 9 is connected with the fixing portion 7, the supporting leg 9 can be burned off when a large current flows and is disconnected with the fixing portion 7, the insulating layer 6 is arranged on the fixing portion 7 and the fusing portion 8, and the tab 5 is positioned in the inner cavity of the steel shell 1.
