A waterproof usb2.0 connector grounding structure

Abstract

The invention relates to a grounding structure of a waterproof USB2.0 connector, comprising a plastic body, a grounding terminal I, a grounding terminal II, a contact piece and an inner metal shell, and the inner metal shell adopts pre-installation and secondary riveting Fixed in the plastic main body, the contact piece is fixed in the plastic main body by means of forced installation and conducts with the inner metal shell. The two sides of the main body are equipped with a limit structure to fix the positions of the grounding terminal I and the grounding terminal II; after the two grounding terminals are forced into the plastic main body, they are connected to the contact part of the inner metal shell by means of point-surface contact. Resilient contact is achieved by a cantilever beam structure on the ground terminal. The invention has high position accuracy of the grounding welding leg of the terminal, and can prevent the welding leg from being deformed by force when the product is welded to the PCB board. Moreover, the grounding terminal is small in size and low in component cost, which can realize automatic assembly and assembly, and reduce product cost.

Description

technical field [0001] The invention relates to a waterproof USB2.0 connector grounding structure. Background technique [0002] With the improvement of consumer experience requirements, traditional mobile phone adapters without waterproof performance can no longer meet market demand. In the future, the mobile phones launched by mainstream mobile phone manufacturers in the market will require waterproof performance for their matching adapters. Therefore, the commonly used output interface USB2.0 connector needs to be designed and customized for waterproof performance. At present, the commonly used USB2.0 waterproof connector uses two independent metal shell parts to realize the grounding function. The two independent metal shell parts include an inner metal shell and an outer metal shell. The inner metal shell is provided for mutual matching with the plug The insertion and extraction force at the same time and the elastic contact with the plug shell, the outer metal shell a...

AI Technical Summary

Problems solved by technology

[0003] (1) The outer metal shell is buckled on the insulator in an up-and-down manner, and the grounding leg is integrated with the outer metal shell. Due to the limitation of the bending accuracy of the mold, the position of the grounding leg is poor, which may easily cause the machine to support the product. When the PCB board is welded, the foot is deformed by force;

[0004] (2) The volume of the outer metal shell is large, and the cost of parts is high. At the same time, due to structural limitations, it is very difficult to assemble the metal shell with an automatic machine, resulting in low assembly efficiency and high cost.
