Description

Novel disk type copper nickel plating tab Technical Field The utility model relates to the technical field of battery parts, in particular to a novel disc-type copper nickel-plated tab. Background The disc-type copper nickel-plated tab is a core conductive component of a power battery and a high-rate energy storage battery, can adapt to a large-current charge-discharge scene by virtue of excellent conductivity of a copper base material and corrosion resistance of a nickel coating, and has become one of the main modes of the tab in the new energy field because a disc-type winding structure can be compatible with an automatic production line. The metal belt and the tab glue of the existing disc-type copper nickel-plated tab are exposed to the external assembly environment, the edge of the tab is easy to scratch by a conveying roller way and a cutting knife in the winding conveying and cutting positioning processes of an automatic production line, so that a nickel coating is damaged, further a copper base material is corroded by electrolyte, if a tool collides during assembly, the tab glue is easy to crack, the sealing base of the tab glue and a battery shell is damaged, the risk of leakage is increased, and in a multi-cell stacking scene of a power battery module, unprotected tabs are easy to deform due to extrusion of adjacent cells, so that a conductive path is deviated. The existing disc type copper nickel-plated tab is connected with an external collector bar and a connector by laser welding or rigid bolt crimping, wherein although initial contact resistance is low in welding connection, under the conditions of bump road conditions of a vehicle-mounted power battery and long-term vibration of an energy storage battery, micro cracks are easily generated on welding spots due to metal fatigue, so that the contact resistance is suddenly increased, local heating is caused, the tab is burnt out seriously, assembly tolerance cannot be compensated by rigid bolt crimping, tab glue is easily crushed due to overlarge pressure, or a contact gap is easily formed due to insufficient pressure, and the conductivity stability is reduced. Disclosure of utility model The utility model aims to solve the technical problem that the assembly tolerance cannot be compensated in the using process of the lug in the prior art, and provides a novel disc-type copper-plated nickel lug. In order to achieve the above purpose, the novel disc-type copper nickel plating tab comprises a shell, the tab is arranged in the shell, a control component is arranged in the shell, the control component comprises a plurality of mounting grooves, the mounting grooves are formed in the inner wall of the shell, fixing grooves are formed in the two sides of the inner wall of the mounting grooves, rotating rollers are arranged in the mounting grooves, the two ends of each rotating roller are rotationally connected with the bottoms of inner cavities of the fixing grooves on the two sides, coil springs are sleeved at the two ends of each rotating roller, a moving seat is fixedly sleeved on the surface of each rotating roller, one end, far away from each rotating roller, of each moving seat is fixedly connected with a connecting seat, one end, far away from each moving seat, of each connecting seat is fixedly connected with a lower pressing plate, and the bottoms of the lower pressing plates are in contact with the tab. Preferably, the top of the shell is fixedly connected with a sealing disc. Preferably, threaded holes are formed in two ends of the sealing disc.
