Abstract
The utility model discloses a rotation prevention type cylindrical aluminum case battery anti-explosion combined cover plate. The rotation prevention type cylindrical aluminum case battery anti-explosion combined cover plate comprises a cover plate (1), anti-explosion pieces (2), isolation rings (3), pore plates (4) and a connecting piece (5), wherein each isolation ring (3) and each pore plate (4) wrap up each anti-explosion piece (2), each anti-explosion piece (2) is in a Z-shaped structure, and each isolation ring (3) is provided with a positioning boss (6). The cover plate (1) is made of aluminium alloy, the anti-explosion pieces (2) are made of pure aluminium, the pore plates (4) are made of pure aluminium, the isolation rings (3) are made of high polymer materials, and the connecting piece (5) is an aluminium-nickel composite piece. According to the technical scheme, each anti-explosion piece (2) is in the Z-shaped structure, and therefore overturning space is increased, and burst pressure is enabled to more stable. Each isolation ring (3) and each pore plate (4) wrap up each anti-explosion piece (2), so that a power outage function is increased. The boss playing a role in positioning is designed on each isolation ring, and therefore mechanical fixing is increased, and shock resistance of a battery is reinforced.
Description
Technical field
The utility model relates to a kind of combination plate of electrokinetic cell, especially relates to the explosion-proof combination plate of a kind of cylindrical aluminium housing battery.
Background technology
The interior airtight non-hydrolyzate that has of electrokinetic cell, when the faults such as the undue charging of charger appearance or mistake use, normal meeting produces abnormal gas at inside battery, and the gathering of abnormal gas can make inside battery produce excessive pressure.The direct pressure release of explosion-proof valve causes electrolyte to overflow when abnormal, contaminated environment, and part around the corrosion, some battery does not have explosion prevention function, and fail safe is low.Battery can cause the relative motion of volume core and cover plate when rocking, pull easily solder joint between orifice plate and the burst disk, causes outage unusual.
Summary of the invention
In order to solve above technical problem, the utility model provides a kind of Rotaryproof-explosion-proof combination plate of cylindrical aluminium housing battery.
A kind of Rotaryproof-explosion-proof the combination plate of cylindrical aluminium housing battery comprises cover plate 1, burst disk 2, cage ring 3, orifice plate 4 and brace 5, described cage ring 3 and orifice plate 4 parcel burst disk 2, and described burst disk 2 adopts " Z " type structure; Be provided with positioning boss 6 on the described cage ring 3.
Described cover plate 1 is aluminium alloy, and described burst disk 2 is fine aluminium, and described orifice plate 4 is fine aluminium, and described cage ring 3 is macromolecular material, and described brace 5 is aluminum-nickel compound piece.Cage ring 3, orifice plate 4 and cover plate 1 adopt mechanical anti-rotation location.
Adopt the technical solution of the utility model, burst disk 2 adopts " Z " type structure, has increased the upset space, so that burst pressure is more stable, cage ring 3 and orifice plate 4 parcel burst disk have increased power down function; Designed the boss that plays the role of positioning on the cage ring, increased mechanical fixing, the shock resistance of battery is increased.
The battery normal operation can guarantee low energy consumption.When the battery abnormal inside battery is opened circuit, burst disk can in time be broken the more reliable safety protection function of effectively bringing into play explosion-proof combination plate when serious.During the battery strenuous vibration, the whole together vibrations of cover plate can prevent the battery failure that orifice plate, brace etc. come off and cause.

Embodiment
A kind of Rotaryproof-explosion-proof the combination plate of cylindrical aluminium housing battery comprises cover plate 1, burst disk 2, cage ring 3, orifice plate 4 and brace 5.
Described cage ring 3 and orifice plate 4 parcel burst disk 2, burst disk 2 is connected with orifice plate 4, and described burst disk 2 adopts " Z " type structure, during the battery charging and discharging abnormal, the electrolyte gasification causes cell internal pressure to increase, and burst disk 2 breaks away from orifice plate 4, so that cell internal pressure discharges.
Be provided with positioning boss 6 on the described cage ring 3, positioning boss 6 matches with shrinkage pool on the cover plate 1, can prevent that the rotation of cover plate 1 from coming off.Described cover plate 1 is aluminium alloy, and described burst disk 2 is fine aluminium, and described orifice plate 4 is fine aluminium, and described cage ring 3 is macromolecular material, and described brace 5 is aluminum-nickel compound piece.Cage ring 3, orifice plate 4 and cover plate 1 adopt mechanical anti-rotation location.
Adopt the technical solution of the utility model, burst disk 2 adopts " Z " type structure, has increased the upset space, so that burst pressure is more stable, cage ring 3 and orifice plate 4 parcel burst disk have increased power down function; Designed the boss that plays the role of positioning on the cage ring, increased mechanical fixing, the shock resistance of battery is increased.
The battery normal operation can guarantee low energy consumption.When the battery abnormal inside battery is opened circuit, burst disk can in time be broken the more reliable safety protection function of effectively bringing into play explosion-proof combination plate when serious.During the battery strenuous vibration, the whole together vibrations of cover plate can prevent the battery failure that orifice plate, brace etc. come off and cause.
