Background

At present, the main interfaces of HDMI and DP are small reed contact products in the civil field, such as RJ45 (crystal head), which have poor environmental resistance such as shock resistance and tensile resistance and cannot meet the use in a severe environment, while military high-speed connectors are reinforced sheet contact products, under the condition of 20 cores, 6 pairs or even more pairs of high-speed differential pairs may be arranged in a dedicated differential connector, but in practical civil application, after a product with enough cores is often selected, only 2 pairs of differential pairs are used, and the rest differential pairs are used as single-ended signals, which causes functional waste. Most of the existing connectors cannot be compatible with interfaces with different definitions such as HDMI and DP at the same time, which is not beneficial to improving the universality of the connectors.
