Description

Technical Field

[0001] This utility model relates to the field of USB connector housing manufacturing technology, specifically a precision stamping drawing part for manufacturing USB connector housings. Background Technology

[0002] In today's digital age, the information industry is booming at a remarkable pace, becoming a key force driving global economic growth and social change. From early mainframe computers to today's ubiquitous smart devices, the development of the information industry has been full of innovation and breakthroughs, profoundly changing people's lives, work, and communication. In recent years, with continuous technological advancements and gradual cost reductions, personal electronic consumer products have rapidly become widespread, entering millions of households. Whether it's a small and convenient smartphone, a lightweight and portable tablet, or a powerful laptop, these devices have become an indispensable part of people's daily lives. According to statistics, global smartphone shipments have maintained a high level in the past few years, reaching billions of units annually. The sales of tablets and laptops are also considerable, meeting people's diverse needs in work, study, entertainment, and other aspects.

[0003] However, traditional USB connector shells still have many problems in production. Before the application of precision stamping and drawing technology, USB connector shells often adopted the MIM (metal injection molding) process. This process requires multiple steps such as mixing, kneading, crushing, granulating, injection molding, degreasing and sintering of metal powder and binder. The process is relatively complex and the manufacturing cost is high. Moreover, the shell formed by the MIM process is relatively rough and may form pores inside the material. When the USB connector comes into contact with liquid, the liquid may penetrate into the shell, causing damage to electrical components and making it unsuitable for the overall waterproofing of electronic devices.

[0004] Therefore, this utility model provides a precision stamping drawing part for manufacturing USB connector housings to solve the above problems. Utility Model Content
