Processing technology for high-resolution digital interface

Abstract

A manufacturing process of high definition digital interface includes assembling wire rubber plug, rubber plug in stab mode, medium rubber plug and automatic welding unit on said digital interface; pressing each core wire into grooves of wire rubber plug and rubber plug in stab mode, brushing tin solder on core wires and clamping them on automatic welder for carrying out automatic welding, shining light on core wire and terminal wiring end by welder to weld core wire on terminal wiring end by melting tin solder with heating for finalizing said welding at only one time.

Description

Technical field: [0001] The invention relates to the technical field of digital interfaces, and more specifically relates to the processing technology of high-definition digital interfaces. Background technique: [0002] HDMI 1.3 / Micro usb / Dvi / Displayport / udi and other multimedia interfaces (digital interfaces) are high-frequency interfaces in the industry, (HDMI1.3c) can provide data transmission bandwidth up to 10.2Gbps, Microusb can reach 5.1Gbps, and dvi can reach 4.95 Gpbs, udi is faster, can reach 21Gpbs, HDMI 1.3 is used for handheld devices and TV cables, can transmit uncompressed audio signals and high-resolution video signals, and does not need to perform digital / analog or analog / analog before signal transmission Digital conversion can ensure high-quality video and audio signal transmission. For consumers, HDMI technology not only provides clear picture quality, but also greatly simplifies the installation of home theater systems because audio / video uses the same ...

Problems solved by technology

Microusb is used for signal lines between handheld devices and cameras and TVs, Dvi is used for PCs, Displayport is used for PC / TV and other related fields, currently HDMI 1.3 / Microusb / Dvi / Displayport / udi and other digital interfaces There is no structure to support the core wires. As shown in Figure 1, the core wires are arranged in a mess, signal interference will occur between the core wires, and the high-frequency characteristics are poor. When this kind of digital interface is produced, the outermost core wires are first removed. Then peel off the dense network cable, remove the aluminum foil and the inner aluminum foil, then remove the outer skin of the core wire with core stripping pliers, and finally weld the core wires to the interface one by one. The whole process is manually operated. After removing the core wire Only one core wire can be operated at a time when the sheath and welding are performed. For example, there are 19 digital TV connecting wires (four of which are ground wires, and the ground wire has no sheath, so there is no need to remove the sheath), and the core wire sheath needs to be removed. 15 times, the welding will need to be welded 19 times to complete, the work efficiency is low, the quality is unstable, and the size of each tin point 37 is different, and the distance between the terminal terminals 36 is small, it is not easy to weld, and it is easy to cause a short circuit of the connector and glue. The core is burnt, etc., the transmission performance of the connector is unstable, and the yield rate is low
