[embodiment]

Refer to shown in Fig. 1 ~ 3, embodiment of the present utility model is described in detail.

As shown in Figure 1, a kind of cell anti-reverse assembling structure involved by the utility model, described cell anti-reverse assembling structure comprises a battery case 100, and the top 1 of described battery case 100 comprises positive contact sheet 11 and a cathode contact sheet 12, and the bottom 2 of described battery case 100 comprises a Metal Contact sheet 21;

Emphasis consults Fig. 2, and the outer of described positive contact sheet 11 is arranged with a circle first insulation isolation platform 13, and described first insulation isolation platform 13 exceeds positive contact sheet 11; Be provided with one second insulation isolation platform 14 between two contacts 121 of described cathode contact sheet 12, described second insulation isolation platform 14 height is lower than two contacts 121 of described cathode contact sheet 12.

Emphasis consults Fig. 3, bottom described battery case 100, the Metal Contact sheet 21 of 2 is provided with stretch contact 22 and a negative pole of a positive pole and stretches contact 23, the described positive pole contact 22 that stretches is provided with the first insulation separator 24 of an inner recess, and described positive pole contact 22 end that stretches is positioned at the bottom of the first insulation separator 24 recess; The stretch end of contact 23 of described negative pole is provided with a Metal Contact circle 25, is arranged with one second insulation separator 26 in described Metal Contact circle 25, and the height of described second insulation separator 26 is lower than the Metal Contact circle 25 of surrounding.

Described positive contact sheet 11 and first difference in height of isolating platform 13 that insulate is 0.5 ~ 1.5mm.Described second insulation isolation platform 14 is 0.5 ~ 1.2mm with the difference in height of two contacts 121 of described cathode contact sheet 12.The cup depth of described first insulation separator 24 is 0.5 ~ 1.5mm.

The internal diameter of described first insulation isolation platform 13 is slightly less than the external diameter installing battery, therefore when battery is anti-loaded, namely, when the negative pole of battery contacts with positive contact sheet 11, the first insulation isolation platform 13 will block the negative pole of battery, prevents the negative pole of battery from contacting with positive contact sheet 11; And when correctly installing, the head of anode is smaller, just contact with positive contact sheet 11 by the first insulation isolation platform 13.

Cathode contact sheet 12 is provided with two protruding contacts 121, two relative contact 121 conductances that contact with battery cathode, and be provided with the second insulation isolation platform 14 between two contacts 121, when battery is anti-loaded, namely when the positive pole of battery aims at cathode contact sheet 12, the head of anode can only be resisted against on the second insulation isolation platform 14, and cannot contact with the contact 121 on both sides and conduct electricity; And correctly pacify timing, the contact 121 that the negative pole of battery then just can touch both sides is conducted electricity.

Bottom described battery case 100,2 positive poles stretch the first insulation separator 24 of the inner recess that contact 22 is established, as illustrated in the embodiment of figure 3, positive pole contact 22 end 221 that stretches stretches into inner recess place by a breach 241 of the first insulation separator 24 side, it can effectively prevent from instead filling energising, when anode aligning positive pole stretches contact 22, anode can smoothly by the recess of the first insulation separator 24, and contact with the positive pole of recess contact 22 end 221 that stretches, and it is anti-when filling, the negative pole of battery is then stuck in the first insulation separator 24 recess outside, cannot with positive pole stretch contact 22 joining distal ends touch.

Negative pole stretch contact 23 place battery install correct time, namely battery cathode aim at negative pole stretch contact 23 time, battery cathode is just stuck on Metal Contact circle 25, then be energized, and during reverse battery installation, anode then stretch into and be resisted against be arranged in Metal Contact circle 25 second insulation separator 26 on, cannot conduct electricity.

Therefore, the utility model is all provided with the mechanism that cell anti-reverse fills at four positions with battery terminal contact, can effectively prevent circuit after cell reverse arranging from still can the situation of conducting occur, ensureing that battery only has installs correctly, power consumption equipment could normal power-up use, prevent from, because battery-heating causes damaging product and internal circuit, extending the useful life of product.

Although the foregoing describe embodiment of the present utility model; but be familiar with those skilled in the art to be to be understood that; specific embodiment described by us is illustrative; instead of for the restriction to scope of the present utility model; those of ordinary skill in the art, in the modification of the equivalence done according to spirit of the present utility model and change, should be encompassed in scope that claim of the present utility model protects.
