Part, positive bus carries bending edges, and cylinder lithium cell is provided between positive bus and negative bus-bar.
Described promptly component is every on the outside of four coupler bodies coordinated with the block of cylinder lithium cell positive pole, positive bus
The position of individual promptly component is provided with magnetite, and magnetite is disc.
Screw is respectively arranged with the bending edges of described positive bus and the bending edges of negative bus-bar, positive pole confluxes
Row is provided with screw with being provided with the inside of negative bus-bar on bus-bar, bus-bar, on the screw and bending edges on bus-bar
Screwed hole correspondence, pole is provided with by screw respectively on the bending edges of negative bus-bar and the bending edges of positive bus；
The inside lateral bend of reed of described negative pole water conservancy diversion jump ring, negative pole water conservancy diversion jump ring surface is provided with elongate holes；Institute
The pole stated is made up of brass material.
In this invention：There is the cap that confluxes on negative bus-bar, confluxing in emitting has water conservancy diversion jump ring, water conservancy diversion jump ring, reed is to inner side
Bending, can be tightly battery core negative pole is wrapped up, the contact resistance with very little has radiating concurrently, can produce cell operations
Heat be rapidly scattered to by the cap that confluxes, bus-bar in air.
Both positive and negative polarity bus-bar all leaves the heat produced during circular hole can work battery pack and further lost, and positive pole confluxes
Prominent component can live positive cover cap hook on cylindrical electrical core on row, make stability enhancing of the battery core in battery pack, by battery core
After positive pole has been assembled, further positive pole is clamped with magnetite, contact resistance is further reduced；Conflux disk, facilitates battery pack water conservancy diversion
Connection；Pole, is that chalocopyrite structure has certain degree of hardness, component confluxes partly consistent with bus-bar bending place size, with certain
Thickness, can work river outlet the disperses heat produced, and pole is provided with screwed hole, further facilitates battery pack connection in series-parallel, constitutes
Higher capacity, the battery combination of higher voltage；In this structure, battery case cap uses high ABS material, job requirement is met, in pole
It can be dismembered in the case of end, improve security.
The present invention is safe with easy to assembly, and clever structure rationally, economizes on resources, and saves the time, battery core is not done
Any packing processes, effectively reduce the secondary injury to battery core, further improve battery core performance, improve uniformity, meet more severe
The use condition at quarter；The cylinder lithium cell that the present invention is selected is the common model in market, with cheap, dependable performance, circulation
The advantages of long lifespan.Pole in the present invention has certain degree of hardness for brass, can meet series-parallel use of high intensity and also have concurrently
Certain heat sinking function
The battery case that the present invention is used is ABS material, with some strength, can be wrapped up battery, if using in vapour
The mobile environment such as car, occurs irresistible factor and produces infringement battery pack because powerful external force can be dismembered, power off.Reduce fire
Calamity or blast equiprobability.
