Electrical connector and manufacturing method thereof

Abstract

The invention relates to an electric connector and a manufacturing method thereof. The electric connector comprises an insulation seat body, multiple conductive terminals fixed on the insulation seat body, an inner casing sleeved at outer periphery of the insulation seat body and an outer casing mounted at an outer side of the inner casing, wherein the inner casing is wrapped at the outer periphery of the insulation seat body to form a butt joint chamber, an outer periphery of a main body of the insulation seat body is provided with a groove in a surrounding mode, the inner casing is provided with a first channel, the outer casing is provided with a second channel, the second channel on the outer casing and the first channel on the inner casing are communicated with the groove on the insulation seat body, the electric connector further comprises a sealing component molded on the outer casing, during molding of the sealing component, the sealing component passes through the second channel on the outer casing and the first channel on the inner casing and is correspondingly arranged between the groove of the insulation seat body and an inner surface of the inner casing to form a sealing ring used for sealing a gap between the main body of the insulation seat body and the inner casing. The electric connector has an advantage of improved waterproof performance.

Description

technical field [0001] The invention relates to an electrical connector and a manufacturing method thereof, in particular to an electrical connector with a waterproof sealing structure and a manufacturing method thereof. Background technique [0002] Chinese patent CN201594649U discloses a waterproof connector, which includes a metal shell, an insulating body and a number of conductive terminals, the conductive terminals are accommodated and fixed in the insulating body, and the metal shell covers the insulating body and Conductive terminals, and a matching cavity is formed at the front end. The metal shell includes a metal inner shell and an outer shell. The metal inner shell is provided with at least one fastening hole at a position corresponding to the matching cavity. There is a stopper, the outer shell covers at least the surface of the metal inner shell provided with the fastening hole and is in contact with the metal inner shell, and the outer shell is provided with a...

AI Technical Summary

Problems solved by technology

In the specific application where the electrical connector is installed on electronic devices such as mobile phones and tablet computers, the existing waterproof structure can prevent water droplets from entering the interior of the electronic device (such as a mobile phone) from the mating cavity through the holding hole. ; but because the metal inner shell is sleeved on the outer periphery of the insulating body, there is a large fit gap between the two, and the water droplets will follow the fit gap from the front end of the electrical connector, that is, from the outside of the electronic device. Access to the back end of the electrical connector is used to install the electrical connector on the PCB board, thereby affecting the normal operation of the electronic equipment, and even causing damage to the electronic equipment due to a short circuit
