Description
Technical Field
The utility model relates to a square aluminum hull battery explosion-proof formula utmost point post.
Background
The short circuit phenomenon can be avoided in the use process of the battery, once the short circuit occurs, the battery can be burnt, and the fire can be seriously caused. In the current structure of the square aluminum-shell battery with wide application, the aluminum pole and the aluminum pole lug are directly and electrically connected in the aluminum shell, and if the circuit is short-circuited and cannot be powered off in time, the pressure in the aluminum shell is increased without releasing, so that the whole aluminum-shell battery is damaged.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: in order to overcome the defects in the prior art, the utility model provides a square aluminum shell battery explosion-proof type pole which can cut off the current in time when the internal pressure of the aluminum shell is increased.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an explosion-proof formula utmost point post of square aluminum hull battery, has aluminum hull, aluminium lid and installs the electric core in the aluminum hull, and electric core is connected with aluminium utmost point ear, and the aluminium is covered and is installed aluminium utmost point post, and the flange of aluminium utmost point post stretches into in the aluminum hull, aluminium utmost point ear upper end link firmly the connection aluminum sheet, the flange terminal surface has interior concave cavity, is equipped with explosion-proof aluminum sheet in the interior concave cavity, and explosion-proof aluminum sheet passes through laser seal welding with flange, and explosion-proof aluminum sheet center is recessed and is connected the aluminum sheet laminating contact, is located the joint between connection aluminum sheet outside edge and the explosion-proof aluminum sheet bottom surface and has the cage, aluminium utmost point post the exhaust.
Furthermore, the peripheries of the isolation ring and the connecting aluminum sheet are fixedly connected with the side wall of the inner concave cavity through curing glue.
In order to better improve the explosion-proof effect, the central part of the joint of the connecting aluminum sheet and the explosion-proof aluminum sheet is provided with a concave cavity which is opened towards the side of the battery core, so that the connecting aluminum sheet at the concave cavity is thinner and easier to break under pressure to release the pressure.
The utility model has the advantages that: the utility model discloses a set up between aluminium utmost point ear and aluminium utmost point post and connect aluminum sheet and explosion-proof aluminum sheet after, when the battery meets accident short circuit and makes the aluminum hull internal pressure increase, break and connect aluminum sheet and explosion-proof aluminum sheet and cut off the power supply to the protection battery inner structure is not influenced.
