Description

Battery case

[technical field]

The relevant a kind of battery case of the present invention, especially a kind of the sealing completely cuts off inside and outside battery pack structure.

[background technology]

Electronic installation now, especially portable electron device, generally by be contained in box body that this electronic installation links to each other in a joint or multiple batteries driving, and above-mentioned box body and electronic installation are made one, or away from electronic installation, again by connecting such as electric installations such as electric wires.

Battery with notebook computer is an example, and general at least one Battery pack is positioned in the lower house of battery case, and the connector that connects this battery and external circuit is arranged in the edge of this battery case, seals this lower house and upper shell with gluing process again.This battery case has following defective in the use:

1, if working with notebook computer touches in the environment of water probability in high wetness, height; one is careless slightly; but just may cause water or other conductive liquid to enter box body inside by the space between connector and the box body; and then dangerous situations such as short circuit appear in the monitoring and protecting circuit board that causes battery being carried out overcurrent, overvoltage, under-voltage, short circuit, recoil etc.; What is more, can burn out expensive cells in notebook computer.

2, if situations such as aging appear in battery, then electrolyte may spill via the space between connector and the box body equally, then may the mainboard of notebook computer be impacted.

In view of this, be necessary to provide a kind of battery case in fact, cell sealing is completely cut off in this battery case.

[summary of the invention]

Therefore, purpose of the present invention promptly provides a kind of battery case that cell sealing is isolated.

For reaching above-mentioned purpose; the invention provides a kind of battery case; be installed with a battery in this battery case in order to sealing; and this battery connects the monitoring and protecting circuit board of tool a connector with a soft board; it comprise structure symmetrically and can cover on; lower house; wherein; on being somebody's turn to do; cave in respectively in the lower house and have second; first receiving space; and on being somebody's turn to do; lower house to this second; first receiving space convexes with second of several symmetries; first spacer; again; on being somebody's turn to do; lower house one side is extended and is somebody's turn to do; the sidewall of lower house parallel and symmetrical respectively second; first body of wall; and the soft board of sheathed first seal of clamping between this two sidewall; and this is second years old; first body of wall with should on; form one second between the sidewall of lower house respectively; first cavity; and this is second years old; offer on first body of wall one be communicated with this second; second of first cavity and space outerpace; first opening, two openings cooperate card to establish the connector of sheathed one second seal.In addition, be convexly equipped with at least two second, the first staggered barricades in this second, first cavity between the side walls in opposite directions, in order to locate this observation circuit plate.

Compared to prior art, the present invention's sheathed seal respectively on the soft board of battery and connector, and the sealing part is pressed on respectively between the sidewall and opening of housing, carry out double-deck protection: even the seal on the connector is owing to reason such as aging closed shell no longer, but water or other conductive liquid cause the short circuit on the observation circuit plate, because the effect of seal on the soft board, but water or other conductive liquid also can not enter battery case inside, damage expensive battery.
