Description
Technical field
The utility model relates to button cell technology, refers to particularly a kind of ultrathin weld tabs button cell.
Background technology
Weld tabs button cell is widely used in electronic product, at present, domestic button cell processor is in the time producing weld tabs button cell, conventionally the method adopting is: first at insulating coating of outer edge portion bag of button cell, then respectively positive plate and negative plate are welded on the positive and negative polarities shell of button cell with spot welding machine point, can complete the production of a weld tabs button cell.The gross thickness H of existing this final products as shown in Figure 1, H=h1+h2+h3+h4 × 2 (thickness that h1 is anodal weld tabs, h2 is the thickness of negative pole weld tabs, the thickness that h3 is battery body, h4 is the thickness of one deck insulating case).Along with electronic product towards ultra-thin, size is little, the development of light method, reducing thickness becomes the development trend of weld tabs button cell.But, from the construction package of weld tabs button cell, the thickness of battery itself is specified by industry standard, can not change, it is also little that thin possibility falls in the thickness of the insulating case using at present, and the full-scale requirement that also needs to meet client of single weld tabs, the thin confined space that adapts to reduce gradually will fall in the thickness of whole weld tabs button thus, its difficulty is well imagined, becomes weld tabs button cell technical problem urgently to be resolved hurrily.
Summary of the invention
The purpose of this utility model will provide a kind of ultrathin weld tabs button cell exactly, and this weld tabs button cell is ensureing, on the good basis of battery serviceability, to have reduced the gross thickness of battery.
For achieving the above object, the technical solution adopted in the utility model is: a kind of ultrathin weld tabs button cell, comprise battery body, described battery body comprises battery case and is built in electrochemical reaction material and the electrode in described battery case, described battery case comprises negative cover and the anode cover of fastening, described negative cover end face is welded with negative pole weld tabs, the laminating of described negative pole weld tabs and described negative cover end face, and be provided with insulating cement in gap between described negative pole weld tabs bottom surface and described anode cover; Described anode cover bottom surface is welded with anodal weld tabs, described anodal weld tabs and the laminating of described anode cover bottom surface.
Further, described insulating cement fills in the described gap between described negative pole weld tabs bottom surface and described anode cover top.
Further, described gap by described negative pole weld tabs bottom surface extend described negative cover end face critical place, be positioned at the described negative cover side edge under described negative pole weld tabs, and the described anode cover top three who is positioned under described negative pole weld tabs surrounds.
Further, described insulating cement radially protrudes from described anode cover edge.Insulating cement extends and projects to edge in anode cover top, is conducive to thoroughly negative pole weld tabs and anode cover insulation be separated, even if there is the situation of negative pole weld tabs pressurized bending, also can avoid the generation of short circuit phenomenon.
Further, described insulating cement extends 1.5~2mm along anode cover top circumferencial direction.
Compared with prior art, the utlity model has following advantage:
One, weld tabs button cell of the present utility model has been avoided the generation of negative pole weld tabs and anode cover contact short circuit phenomenon by the mode of point insulating glue, this weld tabs button cell has saved insulating case, thereby make the existing weld tabs button cell of weld tabs button cell Thickness Ratio in the utility model thickness reduction the thickness of two-layer insulating case, also make cell diameter size reduction simultaneously, and then make this weld tabs button cell can more be widely used for ultra-thin lightweight electronic product, the range of application of significantly having widened weld tabs button cell, has improved product competitiveness in the market.
They are two years old, the utility model good manufacturability, in its production process, save the insulating case that cuts in weld tabs button cell traditional processing technology, cover insulating case, the steps such as thermal contraction, reducing the number of of production technology directly subtracted the defective products producing in these technical processs, improved product qualified rate, lowered production cost.
