Description

The extendibility combined connection apparatus of self-contained battery core

Technical field

The utility model relates to a kind of extendibility combined connection apparatus, is meant a kind of extendibility combined connection apparatus of self-contained battery core especially.

Background technology

Be the response environmental protection, reduce environmental pollution, in the utilization of the Portable energy towards development in pluralism, for the electrical demands characteristic that cooperates multiple different capacity and demand such as easy to use, all can with most suitably battery form in the serial or parallel connection mode and be electrically connected, even be combined into a battery pack; Consult Fig. 1, the solid piece snap-in structure 1 of a kind of battery of existing rechargeable battery capable of being combined, it is six outer equilateral blocks 11 with hexagonal, this block 11 has first 12 and interior ring 121 parts, first 12 with have these six outer equilateral six second 13 and be vertical and be connected, and this each second 13 all have a damascene structures 131, this damascene structures 131 can be public dovetail structure 132 and female dovetail structure 133, block 11 can form clip by this damascene structures 131 with another block and cooperate, and encircles in 121 parts to be fixed in this rechargeable battery core 2 can enter to thus.

The actual back of using is found, answer actual behaviour in service when serial or parallel connection though utilize the solid block structure 1 of battery snap-in, the quantity that can arbitrarily increase and decrease rechargeable battery core 2 is used with demand that should be different, yet along with long use, in case place a certain rechargeable battery core 2 of serial or parallel connection middle position to produce when damaging, serial or parallel connection becomes the block 11 of rechargeable battery set to dismantle one by one, so that change out of order battery, again block 11 being combined into one by one the solid piece snap-in structure 1 of battery again uses, this process is not only loaded down with trivial details and take a lot of work, and uses also very inconvenience; Moreover, on actual the use, because block 11 becomes in solid piece snap-in structure 1 process of battery at serial or parallel connection, only utilize damascene structures 131 to form a no friction tight state that interconnects at the two ends of these rechargeable battery core 2 bodies, block 11 can't form the state that mutual clip cooperates, more be level and smooth circular hole in view of interior ring 121 parts, battery 2 can't effectively be fixed in wherein, if be subjected to external force start influence accidentally, cause battery 2 to produce displacement easily, even get loose, and then the whole use that is electrically connected of organizing rechargeable battery core 2 of influence, be worth improving.
