Fast connection mechanism for formation contact of power battery

Abstract

The invention relates to a fast connection mechanism for a formation contact of a power battery, and belongs to the field of battery production equipment. The fast connection mechanism comprises a main movable rod (5), a contact piece base (6) and contact pieces (7), wherein the contact piece base (6) is fixed at the lower end of the main movable rod (5), and the periphery of the outer side of the contact piece base (6) is provided with a plurality of vertical contact piece grooves at intervals; a plurality of the contact pieces (7) are respectively and vertically arranged in the contact piece grooves, the upper ends of the contact pieces (7) are rotationally connected with the contact piece base (6) through an articulated mechanism, and the outer sides of the lower parts of the contact pieces (7) are provided with at least one contact piece contraction pressure spring (8) in a sleeved way; a pole rod containing cavity (61) used for containing a battery pole rod is formed in the lower part of the contact piece base (6), and the lower parts of the contact pieces (7) penetrate through the contact piece grooves to extend into the pole rod containing cavity (61). According to the fast connection mechanism, the plurality of contact pieces (7) can be tightly connected with the battery pole rod through the contraction force of the contact piece contraction pressure spring, so that fast connection can be smoothly completed under the condition that an error exists in a vertical direction; the convenience for operation is achieved, and high-current charging and discharging can be carried out.

Description
