Description

Separated assembled pole structure and battery Technical Field The utility model relates to the technical field of batteries, in particular to a separated assembled pole structure and a battery. Background At present, a bipolar column structure (used for current input and output and providing welding points for a connecting row) is arranged on a cover plate of the new energy power battery, and the cover plate can be an anode cover plate or a cathode cover plate, so that the new energy power battery is not limited to a certain cover plate. In the prior art, when the rest parts assembled with the circular polar column are not changed, in order to improve the charge flow, namely, the current is improved, the cross section area of the polar column needs to be increased, and at the moment, if the cross section area of the polar column is simply increased, the current is greatly limited by the limit of the width edge of the cover plate piece. In addition, the design of bipolar column structure is higher to the planarization requirement, has the defect that the structure is complicated, the packaging efficiency is low and the cost is high to after the equipment is accomplished to single battery, the welding of bipolar column structure and connection row can increase the material cost. Disclosure of utility model The utility model aims to provide a separated type assembled pole structure, and aims to solve the problem that in the prior art, the pole structure has low assembly efficiency. The utility model discloses a split type assembled pole structure, which comprises a top cover plate, a pole upper section and a pole lower section, wherein the pole upper section and the pole lower section are formed in a split mode, the pole lower section penetrates through the top cover plate and is provided with an upper part extending above the top cover plate, the pole upper section is connected with the upper part, the pole lower section is provided with a lower part positioned below the top cover plate, and the pole upper section is connected with the pole lower section to form a pole. Further, an upper plastic part is arranged on the top cover plate, the lower section of the pole penetrates through the upper plastic part, the upper plastic part is provided with an upward arranged top surface, the bottom of the upper section of the pole is provided with a bottom surface, and the bottom surface is abutted to the top surface from top to bottom. Further, the upper pole section is ring-shaped, the upper pole section is circumferentially arranged along the periphery of the upper portion, a groove ring is arranged on the top face, an upper protruding ring is arranged on the bottom face, and the upper protruding ring is embedded in the groove ring.
