Method for manufacturing high-frequency data cable synchronizing drawing tablet and computer

Abstract

The invention discloses a method for manufacturing a high-frequency data cable synchronizing a drawing tablet and a computer. A high-purity copper wire core is adopted for the high-frequency data cable, a high-frequency signal transmission technology is adopted, so that signal transmission is stable, signal cross interactions are reduced, and EMI is isolated. According to the method, the level of the manufactured high-frequency data cable is superior to the industry level of a high-frequency data cable of the high-frequency association; according to the association level, the swinging frequency of an HDMI cable is 5000 times, and the weight of an end stopper is 250g; according to a real test of the data cable manufactured through the method, the swinging frequency of the HDMI cable is 5000 times, and the weight of the end stopper is 500g; the test result is superior to the requirements of the association, and the attenuation and impedance defects of the high-frequency data cable in a common industry are overcome; HOT-BAR welding of flat cable clips is developed, a clamp is used for matching insulating bushings, four layers of circuit boards are designed, so that connector space reaches an extreme, connector thickness is thinnest, and the bottleneck of the small connector space is broken through; besides, the current high-frequency transmission technology is integrated with the method so that the HDMI cable, an USB cable and POWER cable can work synchronously.

Description

Technical field [0001] The invention relates to a method for preparing a high-frequency data line synchronized between a drawing tablet and a computer. Background technique [0002] At present, the high-frequency data transmission line on the market has a single function. If customers need to synchronize their work during the use of Note book, PC or TV, they often need to use different high-frequency data transmission lines to switch in order to achieve the effect of synchronous operation, such as customers need to draw. When the tablet is transferred to the computer to display the video screen synchronously, you need to connect the HDMI high-frequency data transmission line first, and then connect the POWER data transmission line for power supply. Two kinds of wiring harnesses are needed to achieve the final effect, and the process is cumbersome. Due to structural limitations and technological limitations, there has been a lack of high-frequency data lines that can integrate the...
