Earphone connector and its preparation method, mobile terminal with the earphone connector

Abstract

The invention is applicable to the technical field of earphone connectors and discloses an earphone connector and a manufacturing method thereof, a mobile terminal having the earphone connector. The earphone connector includes an earphone holder main body has one end provided with a jack for insertion of an earphone plug, a sealing wax piece which is embedded in the jack, a terminal assembly which is inserted to the earphone holder main body, a rear cover assembly which covers the two sides of the earphone holder main body, and a sealing assembly which is filled between the rear cover assembly and the earphone holder main body. According to the invention, the sealing wax piece characterized by high-temperature resistance and insusceptibility to shrinkage or deformation is installed to the jack of the earphone holder main body, and a product can be directly subject to an IR furnace and welded to a PCB, such that the earphone connector addresses the problem of manual welding of conventional water-proof earphone holders, increases the efficiency of welding PCBs, lowers manufacturing cost of products, and meets requirements for water resistance in a manner that even if the earphone connector is in water under a certain pressure, water does not easily get into the mobile terminal via through the earphone holder.

Description

technical field [0001] The invention belongs to the technical field of earphone connectors, and in particular relates to an earphone connector, a preparation method thereof, and a mobile terminal provided with the earphone connector. Background technique [0002] With the development of science and technology, electronic equipment has become a mobile terminal integrating entertainment, multimedia interaction and other functions. In this way, more requirements are put forward for the performance of mobile phones. More and more fashion people want to be in the water While swimming or diving, electronic devices can be used to listen to music, watch videos, take pictures, make and receive calls, etc., thereby requiring the electronic device to have a waterproof function at the plug connection with the earphone. However, in the prior art, limited by the manufacturing process, the earphones are prone to water ingress when they are placed under a certain pressure for a long time. ...

AI Technical Summary

Problems solved by technology

However, in the prior art, limited by the manufacturing process, the earphones are prone to water ingress when placed under a certain pressure for a long time

In addition, ordinary silica gel cannot be soldered to the PCB board at high temperature (the maximum temperature is 160°C), and manual soldering is required, resulting in relatively high production costs for the earphones.
