The reed of described negative pole water conservancy diversion jump ring bends to the inside, and negative pole water conservancy diversion jump ring surface is provided with elongate holes; Described pole is that brass material is made.
In this invention: negative bus-bar has the cap that confluxes, conflux in emitting and have water conservancy diversion jump ring, water conservancy diversion jump ring, reed bends to the inside, tightly battery core negative pole can be wrapped up, there is very little contact resistance, have heat radiation concurrently, the heat that cell operations produces can be fallen apart in air by the cap that confluxes, bus-bar rapidly.
Both positive and negative polarity bus-bar all leaves circular hole and the heat produced in battery pack work can be lost further, positive cover cap hook on cylindrical electrical core can be lived by component outstanding on positive bus, the stability of battery core in battery pack is strengthened, after battery core positive pole has been assembled, further positive pole is clamped with magnetite, reduce contact resistance further; Conflux disk, facilitates battery pack water conservancy diversion to connect; Pole, for chalocopyrite structure has certain degree of hardness, component confluxes partly and bus-bar bending place consistent size, have certain thickness, the disperses heat that river outlet work can be produced, pole has screwed hole, further facilitate battery pack connection in series-parallel, form more high power capacity, more high-tension battery combination; In this structure, battery case cap adopts high ABS material, meets job requirement, can dismember in extreme circumstances, improves fail safe.
The present invention has easy to assembly, and fail safe is high, and structure is rationally ingenious, economizes on resources, and saves time, and does not do any packaging process to battery core, effectively reduces the secondary injury to battery core, improves battery core performance further, improve consistency, meet harsher service condition; The cylinder lithium cell that the present invention selects is the common model in market, has low price, dependable performance, and the advantage such as have extended cycle life.Pole in the present invention is that brass has certain degree of hardness, can meet the series-parallel use of high strength and also have certain heat sinking function concurrently
The battery case that the present invention uses is ABS material, has some strength, battery can be wrapped up, if be used in the environment of movement such as automobile, irresistible factor occur and produces and damage battery pack and can dismember due to powerful external force, power-off.Reduce fire or blast equiprobability.
