With the continuous advancement of science and technology, many computer interface devices have been manufactured one after another. In order to enable the computer to be electrically connected to these new generation interface devices, many connection ports of different specifications are installed on the computer motherboard, so that the computer can be electrically connected to the interface device through the transmission line, so that the computer can output control signals Either transmit the data to the interface device, or provide the interface device to return the data to the computer.

In recent years, electronic devices are designed to be lighter, thinner, shorter, and smaller. Even the computers currently on the market are being made in the direction of miniaturization. Correspondingly, the size of the motherboard inside the computer is also reduced. Under the condition that the size of the motherboard is reduced and the space of the motherboard is limited, how to install a variety of connection ports with different specifications becomes an extremely important issue.

For example, there is a new monitor specification that allows consumers to use PCs, TVs and projectors with sharper picture quality and fewer cables. This specification is called "DisplayPort" and allows high-quality audio signals to share the same cable with video signals and transmit them in a total of four lines at a data transfer rate of up to 10.8Gb per second; The number of lines is less than the current cable interface. In addition, there is currently the most popular high-resolution multimedia interface (HDMI), which can provide data transmission bandwidth up to 5Gbps, and can transmit uncompressed audio signals and high-resolution video signals. The advantage of using HDMI is that only one HDMI cable is needed to transmit audio and video signals at the same time, which is different from the traditional way of connecting multiple cables, which greatly simplifies the installation process of the home theater system.

If the DisplayPort and HDMI electrical connectors are to be installed on the motherboard 100 as shown in FIG. Or the HDMI electrical connector is stacked on one or two connectors 200 to install the DisplayPort and HDMI connection ports on the motherboard 100 , which causes a lot of inconvenience in the manufacture of the motherboard 100 .
