Embodiment
The invention will be further described by embodiment below in conjunction with accompanying drawing.
Present embodiment is a syndeton between example explanation the present invention's electricity core positive and negative electrode and lead-out terminal with the 9V lithium battery.
Referring to Fig. 2～4, a kind of lithium battery leading-out terminal structure, this lithium battery is in series by three 3V electricity cores 5, positive and negative electrode 7 elder generations of three electric cores 5 are connected with pad 8 spot welding on the socket 2, then electric core is put into battery lower casing 6, middle cover 1 covers battery lower casing 6, and the top pads 9 that is provided with on the hd top face during the plug on the middle cover 1 can connect the positive and negative electrode 7 of electric core 5 in the battery lower casing 6 is drawn, and constitutes the 9V lithium battery.
In cover injection molded three groups of plugs arranged, every group of plug comprises interconnective two kinds of plugs, a kind of plug 4 is used for electric core positive and negative electrode is connected with cell snap, the one end stretches out to the battery lower casing from the middle cover bottom surface, be connected with the socket combination and with electric core positive and negative electrode, the top pads 9 that is provided with on its other end and the middle hd top face is connected, top pads 9 with on the double buckle that covers be connected.Another kind of plug then is used for the interconnective of three groups of plugs.
A kind of plug 4 that covers in the correspondence is provided with socket, socket 2 main bodys are concave shape, and socket groove internal fixation has Die for Reeds of Connector Jack 3, and socket one sidewall is provided with the pad 8 that is connected with Die for Reeds of Connector Jack, this pad is used for being connected with electric core positive and negative electrode 7 spot welding, does not need additionally to adopt other lead.
Corresponding three electric cores are provided with three sockets 2, during assembling respective pad 8 spot welding on the positive and negative electrode 7 of three electric cores 5 and three sockets or soldering together, then three electric cores are put into battery lower casing 6, middle cover 1 then is installed on the battery lower casing, corresponding in the 4 corresponding Die for Reeds of Connector Jack of inserting in the socket 23 of a kind of plug on the middle cover 1, thereby three electric cores are together in series and draw, then middle cover and battery lower casing are integral the sealed electrical core by ultrasonic bonding.Again the double buckle of loam cake is connected with the middle cover pad at last, loam cake and middle cover supersonic welding are connected together.
