Multimedia connector

This creation is related to a connector structure, and in particular to a multimedia connector.

Traditional multimedia connectors, such as VGA, DVI and other interfaces have limited transmission capabilities, so the HDMI (High Definition Multimedia Interface) connector has been developed, which is an all-digital image and sound transmission interface that can transmit uncompressed Signals such as audio and video. And with the increase in the transmission signal, HDMI 2.0 also came into being.

However, due to the high-speed transmission of HDMI 2.0, electromagnetic interference (EMI) is extremely likely to occur. In the past, many methods have increased the contact point of the HDMI connector when the male and female are docked, which means that the electromagnetic interference is reduced by increasing the number of contact positions, but the effect is still limited, and it is even difficult to pass tests such as EMI or safety.

In view of this, the creator has made great efforts to solve the above problems by focusing on the above-mentioned prior art, and has devoted himself to the application of the theory, that is, the goal of the creator's improvement.
