The invention discloses a plastic junction box for ships, comprising an upper cover, a shell and multiple metal threaded lantern rings. The shell has a cavity, and the upper cover is in sealing fit with the cavity. The outer side of the shell is equipped with a plurality of joint bases integrated with the shell, and each joint base has a through hole communicated with the cavity. The threaded lantern rings are disposed in the through holes respectively. The circumference of each threaded lantern ring has multiple axially-distributed ring slots which fit into the side wall of the corresponding through hole. The joint base contains a plurality of reinforcing ribs which are uniformly distributed along the circumference and connected with the shell. The plastic junction box for ships of the invention has high strength, a firm structure and an enhanced sealing effect.
Description
technical field [0001] The invention belongs to the field of marine electrical equipment, in particular to a marine plastic junction box. Background technique [0002] Marine plastic junction boxes are generally installed on ships to connect and place wires, making them an indispensable part of electrical equipment.
