Waterproof cable connector

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.

Description

technical field [0001] The invention relates to an electrical connector, in particular to a cable connector with excellent waterproof performance. Background technique [0002] Chinese patent ZL 03228668.6 discloses a waterproof connector, which is composed of a male connector with a male terminal and a female connector with a female terminal that can be inserted into the male terminal; The male terminal is covered by an outer covering body. The outer covering body of the male connector is closely connected from the end of the insulator of the cable to the base of the male terminal, and its outer periphery surrounds the male terminal and extends toward the head of the terminal. A fitting recess is formed on the inner side of the outlet; the female connector is formed by connecting a female terminal to the conductor of the cable and covering it with an outer covering, and the outer covering of the female connector extends from the end of the insulator of the cable to the end ...

AI Technical Summary

Problems solved by technology

However, since the terminal is made of metal material, after injection molding the outer casing of the plastic material, the coefficients of thermal expansion and contraction of the two materials are different, and the two themselves belong to different materials, so it is easy to produce a gap at the junction of the terminal and the outer casing. Water can easily seep into the product through the gap between the two, causing the product to fail, so its waterproof ability still needs to be improved

Moreover, this waterproof structure with fitting recesses and fitting protrusions can only be applied to the connection between the male connector and the corresponding female connector, and cannot be applied to electronic devices with special shapes specified by customers, such as alarms. When connected to a device, etc.
