Explanation, the content that embodiment refers to not is restriction to the utility model.
It please refers to Fig.1 with shown in Fig. 2, a kind of positioning formula lithium battery of the utility model, including battery main body 1, edge are buried into
Type 1 one end of battery main body charge connector 2, positive cartridge 3 and conductive sheet 4, charge connector 2 be located at battery main body 1 with just
Between cartridge 3, the negative plate 5 and positive plate 6 in 1 other end of battery main body be set, conductive sheet 4 is for being connected positive cartridge 3 and just
Pole piece 6, negative plate 5, positive plate 6 are electrically connected with battery main body 1 respectively, and negative plate 5, positive cartridge 3 are for exporting battery main body 1
Electric energy, positive cartridge 3 is equipped with positioning contact 7, outer surface one of the positioning contact 7 from side of the positive cartridge 3 far from battery main body 1
Body projects, and the cross-sectional shape of positioning contact 7 is non-circular, for example, the cross-sectional shape of positioning contact 7 can be ellipse
Shape, triangle, rectangle etc..
When practical manufacture, battery main body 1, charge connector 2, positive cartridge 3 and conductive sheet 4 are encased in injection mold,
It is arranged using the special shape of positioning contact 7 so that positive 3 strong fix of cartridge is being noted in injection mold into injection mold
During entering melt plastic cement, prevent positive cartridge 3 from being rotated by the impact of melt plastic cement, the manufacture for promoting lithium battery is good
Rate；After the completion of waiting for lithium battery manufacture, positive cartridge 3 buries molding via edge and is steadily fixed on battery main body 1, in the use of lithium battery
In the process, prevent positive cartridge 3 from being moved relative to battery main body 1.
In the present embodiment, the cross-sectional shape of the positioning contact 7 is that regular hexagon utilizes existing skill when reality manufactures
The mold machine-shaping positioning contact 7 of dresser nut in art is reduced without being 7 individually designed configuration molding die of positioning contact
The manufacturing cost of positive cartridge 3.
The positioning formula lithium battery further includes plastic cement protection board 8, one end of battery main body 1, charge connector 2, positive cartridge 3
And conductive sheet 4 buries molding together via the edge of plastic cement protection board 8, when battery main body 1, charge connector 2, positive cartridge 3, conductive sheet
4, after the edge of plastic cement protection board 8 buries molding together, between positive cartridge 3 and battery main body 1, charging connects plastic cement protection board 8
A part for the part, conductive sheet 4 that connect device 2 is inlayed to bury and is molded in plastic cement protection board 8.
The positive cartridge 3 is provided with datum plane close to the side of battery main body 1（It is not shown in figure）, conductive sheet 4 is equipped with
For contradicting the elastic bumps 9 on datum plane, when reality manufactures, first by battery main body 1, charge connector 2, positive cartridge 3
It is placed in the die cavity of injection mold, then contradicts the elastic bumps 9 of conductive sheet 4 on the datum plane of positive cartridge 3 so that
Flexible deformation occurs for elastic bumps 9, makes conductive sheet 4 and the firm conducting of positive cartridge 3 using the elastic-restoring force of elastic bumps 9,
