Analysis hdmi cable HD cable burned when hot-swappable reasons

hdmi cable HD 19-pin female header, put a half pin, unplugging hdmi high-definition cable, when the root HOT PLUG needle first disconnect and then hdmi high-definition cable circuit detects the disconnect notice input output devices, stops working, hdmi cable acts hot-swappable. The reality is that when hot-swappable high-definition cable hdmi port  is often burned, which is static damage by hdmi HD line is very high-speed WISDOM 24 port patch panel digital signal, because of the need speed, sending and receiving chip design, the use of anti-static protection Circuit generally only 5-8KV electrostatic voltage capability, but in real life, if the environment is dry, while there are static voltage conditions, thousands of static voltage V is common in the design of sophisticated source and display side, the general are arranged to sacrifice some margin capacitance ESD protection circuit. hdmi cable, but WISDOM patch panel  some machines in order to save costs without ESD protection circuitry, it may burn when inserted into the chip with static electricity, which is, do HDMI wire testing friends certainly know, there are anti-static requirements, this is the same reason. Another reason related to the grid: Our 2-pin power socket is no ground. General users when installing LCD TVs and projectors, will not another ground wire. This makes it easier to form an electrostatic. For these reasons, in the definition of hdmi cable hot swappable, you  WISDOM optical fiber cable must first blessing, the character of the fight. Online hot-swappable port or device is burned two reasons. Therefore, manufacturers generally do not recommend hot-swappable HD hdmi cable.
