Waterproof USB connector mother plug structure and manufacturing method therefor

Abstract

The invention reveals a waterproof USB connector mother plug structure and a manufacturing method therefor. The structure comprises a metal terminal, a plastic body which is buried with the metal terminal for forming, a fixed metal piece which is clamped on the surface of the plastic body, a main metal housing which wraps the plastic body, an outer metal housing which wraps the external surface ofthe main metal housing, and glue which is used for sealing one end face of the main metal housing and is disposed in a gap between the plastic body and the main metal housing. The main metal housingand the outer metal housing are welded together, and the main metal housing achieves the fixed connection with the plastic body in a mode of being welded with the fixed metal piece. The structure provided by the invention can achieve the waterproof function, also can reduce the size of a product, and improves the binding intensity of the product.

Description

【Technical field】 [0001] The invention belongs to the technical field of connectors, in particular to a waterproof USB connector female plug structure and a manufacturing method thereof. 【Background technique】 [0002] The competition in the mobile phone market is fierce. Recently, the USB waterproof function has become the new favorite of end users and major mobile phone manufacturers. Mainstream brands such as Apple, Samsung, and Huawei have introduced waterproofing into their next-generation flagship models, and most of the current waterproof USB in the market is through a casing. After dispensing glue, the volume of the finished product is too large, but as the current mobile phone becomes lighter and thinner, the original waterproof seal is to carry out Molding molding on the back end surface of the plastic body and the main shell after the assembly is completed to form a plastic The waterproofing of the back is realized by the sealing and covering part, and the cost is...
