Conductive insert installation tool for lithium ion battery

Abstract

The invention discloses a conductive insert installation tool for a lithium ion battery. The conductive insert installation tool at least comprises an upper holding rod, a lower holding rod, a pressing rod and a fixing rod, wherein the upper holding rod and the lower holding rod are used for bearing the palm holding force and arranged in parallel; the pressing rod is used for connecting the upper holding rod with the lower holding rod, the upper end of the pressing rod is fixedly connected with the side wall of the upper holding rod, and the upper holding rod is perpendicular to the pressing rod; the pressing rod is provided with a cavity with the open lower end, a sliding hole making the lower holding rod move conveniently in the axial direction of the pressing rod is formed in the side wall of the pressing rod, and the lower holding rod is movably connected with the pressing rod through the sliding hole; the fixing rod is used for being connected with a stud of the lithium ion battery, located in the cavity and fixedly connected with the lower holding rod; and the fixing rod is provided with a connecting cavity for being connected with the stud of the lithium ion battery and an internal thread is arranged on the inner wall of the connecting cavity. By the adoption of the technical scheme, a conductive insert and a battery part are assembled and the conduction reliability of a storage battery pack is greatly improved.

Description

technical field [0001] The invention relates to the technical field of lithium ion batteries, in particular to a conductive insert installation tool for lithium ion batteries. Background technique [0002] Due to assembly reasons, flanges with a diameter greater than 11mm cannot be designed on the polished rod of the lithium-ion battery. To improve the conductivity, inserts must be used after installation. In the traditional technology, the relationship between the insert and the polished rod is an interference fit, which cannot be realized by ordinary assembly methods. It is necessary to design special tools and use a certain pressure to achieve the above assembly. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a conductive insert installation tool for lithium ion batteries. The conductive insert installation tool for lithium-ion batteries fixes the threaded part through the relative motion relationship betwee...
