Summary of the invention
For achieving the above object, the technical solution adopted in the utility model is: a kind of grafting integral type lithium battery structure, comprise lithium battery body and protective circuit module, protective circuit module and lithium battery body are fixed into one, wherein, positive and negative electrode on the lithium battery body is connected with the respective end of protective circuit module respectively through lead-in wire, its innovation is: the end at the lithium battery body is provided with a grafting fixing body, embed a socket or plug in this grafting fixing body, the terminal on socket or the plug is connected with the respective end of protective circuit module respectively through lead; Skin at the combinations thereof body adopts thermoplastic tube to be packaged into integral body, and wherein, the interface of socket or plug exposes.
Related content and change interpretation in the technique scheme are as follows:
1, in the such scheme, described lithium battery body is meant the lithium battery entity part, and this part is existing known technology.Described protective circuit module is meant with the lithium battery entity part and cooperates the protective circuit part of carrying out work, this part normally to adopt IC nation to decide the lithium battery protection circuit of technology microminiaturization that its circuit structure is existing known technology.
2, in the such scheme, described " protective circuit module and lithium battery body are fixed into one " is meant that both entities spatially closely link together, and forms integral structure.The protective circuit module can be made into the hypomegetic circuit board of a slice usually, and this circuit board can be close to lithium battery body side and fix, and also it can be hidden in the space of lithium battery body end.
3, in the such scheme, described grafting fixing body is a kind of shape insulating component identical with the lithium battery body, and the effect that this insulating component is set is for mounting receptacle or plug.Described socket or plug are used for being connected with external circuit.Described assembly is meant totally integrated on hardware of lithium battery body, protective circuit module, grafting fixing body, socket or plug and relevant connection lead.
4, in the such scheme, described lithium battery body can be designed to cylinder, and the grafting fixing body also can be designed to cylinder, and socket or plug embed an end of grafting fixing body cylinder, and the cylinder of the other end of cylinder and lithium battery body is spliced into integral body.Described cylinder comprises various geometric form cylinders such as cylinder, oval cylinder, rectangle cylinder.
5, in the such scheme,, can be provided with circular groove structure in the peripheral sides of grafting fixing body in order to improve the reliability that the combinations thereof volume surrounding adopts the thermoplastic tube encapsulation.
The utility model operation principle is: the end at the lithium battery body is provided with a grafting fixing body, embed a socket or plug in the grafting fixing body, during use,, and assembly is placed connection and the installation that can finish lithium battery as long as external circuit plug or socket are pegged graft with it.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, the utility model can adopt with plug-in type and install, so corresponding opening is less on the product casing, is particularly suitable for small-sized or portable product.
2, spring structure is not adopted in the utility model location and electrical connection, but finishes by socket and plug, so connection reliability is higher.
3, the utility model need not adopt battery case that lithium battery is installed as long as design a grafting fixing body, and is therefore easy to make, and cost is low.
4, the utility model is easy to install.
