One of major reason, the both positive and negative polarity on battery top cover combination, which draws leading-out terminal, to be spaced apart with felt pad, relatively
Both are exposed for battery compartment, and the distance between the two poles of the earth are close, if once have material displacement in battery,
Positive terminal or negative pole end marginal deposit are in heaps, it is easy to climing to cross felt pad, cause the short circuit between both positive and negative polarity, or in battery
Conductive impurity is also easy to connect both positive and negative polarity in this place, causes battery bulging or blast, reduces internal short-circuit on this position
Most efficient method is will thoroughly to be blocked between both positive and negative polarity.
Chinese patent CN201008004Y, which is directed in battery, material displacement, positive terminal or negative pole end marginal deposit into
Heap, it is easy to climing to cross felt pad, causes the short circuit between both positive and negative polarity, or the conductive impurity in battery is also easy to connect in this place
Logical both positive and negative polarity, causes the problem of battery bulging or blast, discloses a kind of safety type lithium ion electric core, and it is by blocking battery electricity
Extraction leading-out terminal internal short-circuit on the top cover combination of pond, prevents battery explosion, and it is low that it installs inconvenient, degree of protection.
To sum up, the safety polymer lithium-ion electric core researched and developed a kind of multistage protection, be easily installed is needed at present, to overcome
Lithium-ion electric core installs the low shortcoming of inconvenient, degree of protection in the prior art.

Bottom is provided with the first rubber deduction cap and the second rubber deduction cap, and the first rubber deduction cap is on the upside of the second lug, and the second rubber deduction cap exists
On the upside of first lug, through hole, hole size and the first lug and second are provided with the first rubber deduction cap and the second rubber deduction cap
Lug is consistent, and cell cover is provided with leading-out terminal, and leading-out terminal is on the inside of the first rubber deduction cap, the cell cover left and right sides pair
Claim to be provided with fastener, battery case internal upper part is arranged with clasp, and fastener can coordinate with clasp.
Preferably, foam-rubber cushion is also included, cell cover bottom left is provided with foam-rubber cushion.
Preferably, leading-out terminal bottom scribbles fluid sealant.
Operation principle：Cell cover is fixed through the cooperation of fastener and clasp with battery case, it is easy for installation, now second
Rubber deduction cap seals the first lug, and the first rubber deduction cap seals the second lug, reaches that material exchange is not present in battery compartment.
The utility model is simple in construction, safe, effectively will can thoroughly be blocked between both positive and negative polarity, solve battery bulging or quick-fried
Fried the problem of.
Because also including foam-rubber cushion, cell cover bottom left is provided with foam-rubber cushion, when there is material permeance first in battery
Rubber deduction cap and the displacement of the second rubber deduction cap, foam-rubber cushion can prevent material in heaps in positive terminal or negative pole end marginal deposit.
Because leading-out terminal bottom scribbles fluid sealant, the effect of isolation can be further functioned as.
(3) beneficial effect
