Description

  The present invention relates to a connector, and more particularly to a high resolution multimedia interface connector.

  HDMI (High Definition Multimedia Interface) is a high resolution multimedia interface. The HDMI interface can provide a transmission bandwidth reaching 5 Gbps and can transmit uncompressed audio signals and high-definition visual signals. At the same time, the highest quality audiovisual signal can be transmitted without analog / digital conversion or digital / analog conversion before transmission.

When transmitting an audiovisual signal, the audiovisual signal is transmitted simultaneously by one HDMI line, which is different from the conventional method in which several transmission lines must be connected.
When analog / digital conversion or digital / analog conversion is performed, higher quality audio and visual signals can be transmitted. In other words, HDMI technology can provide consumers with high resolution image quality, and can use the same cable for audio and visual signals, greatly simplifying home theater installation.

  In order to support high-quality audiovisual signal transmission lines, many audiovisual electrical products now have one set of HDMI connectors, which allows users to connect HDMI transmission lines. can do. Conventional HDMI connectors are usually composed of an insulating body, an insulating base, a metal cover, and a conductive terminal.
