USB Type-C connector and fabrication process thereof

Abstract

The invention discloses a USB Type-C connector and a fabrication process thereof. The fabrication process comprises the steps of 1, preparing a first metal strip, a second metal strip and a third metal strip, wherein a first group of terminal and a second group of terminal are arranged on the first metal strip, a first fixed piece and a second fixed piece are arranged on the third metal strip, andan intermediate shielding piece is arranged on the third metal strip; 2, placing the three metal strips in a first injection molding die in a lamination way, and obtaining a first terminal insulationbody and a second terminal insulation body after injection molding; 3, cutting a first terminal module and a second terminal module; 4, laminating the first terminal module and the second terminal module to form a terminal core module; and 5, assembly a metal shell outside the terminal core module. By the fabrication process, the stamping process, the operation process and the injection molding die number are simplified, the production efficiency is improved, the strip waste is reduced, the resource is saved, the die design and development cost is reduced, the process of assembling an upper fixed piece, a lower fixed piece and the metal intermediate shielding piece is omitted, the manual assembly cost is reduced, the production efficiency is further improved, and meanwhile, the product quality is improved.

Description

technical field [0001] The invention relates to the technology in the field of connectors, in particular to a USB Type-C connector and a manufacturing process thereof. Background technique [0002] USB is the abbreviation of Universal Serial BUS (Universal Serial Bus) in English, and its Chinese abbreviation is "Tongxian", which is an external bus standard used to standardize the connection and communication between computers and external devices. It is applied in the field of PC. interface technology. USB was jointly proposed by Intel, Compaq, IBM, Microsoft and other companies at the end of 1994. USB not only has fast transmission speed, but also is very convenient to use. The USB interface also has the advantages of plug-and-play and hot-swappable support for devices, flexible connection, independent power supply, etc., and can be connected to a mouse, keyboard, printer, scanner, camera, flash drive, MP3 machine, mobile phone, digital camera, mobile Hard disk, external...

AI Technical Summary

Problems solved by technology

[0004] The USB Type-C connector in the prior art includes: an insulating body, a plurality of first terminals arranged on the upper part of the insulating body, a plurality of second terminals arranged on the lower part of the insulating body, each arranged on the first terminal / second terminal The upper metal fixing sheet, the metal intermediate shielding sheet arranged in the middle of the insulating body and between the first terminal and the second terminal, and the metal shell structure covering the periphery of the insulating body; the production process adopted in the prior art is a metal intermediate The shielding sheet, the metal fixing sheet and the first / second two sets of metal terminals are formed by punching four strips of material with four sets of stamping dies respectively, after surface electroplating processing, and then put into the plastic mold of the first terminal insulation body / the second terminal insulation body respectively Plastic mold / metal intermediate shield insulation body plastic mold injection molding, then cut the first / second terminal insulation body / metal intermediate shield insulation body with waste tape, and assemble, and then assemble the upper part of the first / second terminal Metal fixing piece, and finally assemble the metal shell; in the above-mentioned manufacturing process, since the first terminal / second terminal / metal intermediate shielding piece are all made separately and then injection molded separately, the assembly, mold design and development costs are high, and the assembly process is complicated; On the one hand, since the two sets of metal terminals are stamped and formed by using two strips separately, two stampings are required, and there is a lot of leftover material after stamping, which is easy to increase the waste of materials and further increase the cost
