Self-adaptive current connecting mechanism for cell box

The utility model relates to a self-adaptive current connecting mechanism for a cell box. The current connecting mechanism comprises an electrode holder, an electrode rear sleeve, an electrode rear cover, a radial spherical plain bearing, an inner box electrode contact terminal, an O-shaped rubber ring, a conductive flange and a nut, and peripheral equipment is an outer box electrode holder; the radial spherical plain bearing is in interference fit with a mounting hole of the electrode holder through an outer ring; one end of the outer ring is pressed against a positioning step in the mounting hole, and the other end of the outer ring is mounted on the electrode holder in a clamping manner through a spring ring; the O-shaped rubber ring is mounted in a ring-shaped groove at the large end of the inner box electrode contact terminal and is in contact with an inner hole of the electrode holder in an extruding manner; the guiding end of the inner box electrode contact terminal is connected with the conductive fla
