Envelope, because gluing is special equipment need to be used to operate, may not possess such machine operating conditions in helpdesk, completely by people
Work gluing, cause gluing uneven, be also easy to produce Seepage, increase the risk of secondary maintenance.
Utility model content
The utility model is intended at least solve one of technical problem present in prior art.Therefore, the utility model carries
For a kind of lithium battery casing, it is therefore an objective to facilitate the maintenance of lithium battery.
To achieve these goals, the technical scheme that the utility model is taken is：Lithium battery casing, including case body, case
Lid, electrical connector and the package board that set window is covered with the case lid for detachable connection and for fully sheathed case, institute
Electrical connector is stated to be arranged in package board.
The window is through the square aperture set in the side wall of the case lid.
The package board is rectangular slab, and package board is attached on the case lid by bolt and positioned at the inside of case lid, envelope
It is the riveting nut that is threadedly coupled that loading board, which is provided with bolt,.
The package board has the mounting hole for allowing the riveting nut to insert, and riveting nut is riveted on package board by cold pressing
On.
Sealing ring is provided between the package board and the case lid.
The sealing ring is the strip flexible glue of hollow.
Lithium battery casing of the present utility model, on case lid increase window structure design, by part it is easily damaged, use frequency
The higher electrical connector of rate is integrated in package board, when the electrical part aging or damage in package board, it is only necessary to pull down encapsulation
Plate, the electrical part of damage is changed, installs and can complete, without dismantling casing, consequently facilitating later period maintenance is changed, after avoiding
The continuous powered-down device of case of changing will dismantle whole case lid, reduce the workload that parts are changed in maintenance, will not damage box sealing, save
Maintenance time has been saved, the mutual cost of dimension of reduction, has reduced repair demolition workload, has reduced the probability of casing secondary seal leakage.
