Abstract

The invention discloses a waterproof cable connector, which comprises two electric joints, a cable connected at the rear ends of the electric joints, and an inner shell and an outer shell wrapped at the rear ends of the electric joints, wherein the front ends of the electric joints protrude forwards and extend out of the outer shell; the joints of the rear ends of the electric joints and the cable are wrapped in the inner shell, and the outer shell is wrapped and formed on the periphery of the inner shell again; the middle part of each electric joint is provided with an accommodating groove, and the front part of the accommodating groove is provided with a screwing part; and a nut and a waterproof shim are correspondingly sleeved on each electric joint, wherein the waterproof shim is correspondingly sleeved on the periphery of the accommodating groove of the electric joint, and the nut is correspondingly screwed on the screwing part of the electric joint and is used for pressing and fixing the waterproof shim to the front end face of the inner shell. Gaps between the electric joints and the inner shell are sealed to prevent external water from entering the inner shell through the periphery of the electric joints.
