[Background of the Invention]

According to the press, most portable computers are equipped with an electronic card connector on the motherboard to enable it to perform telecommunications transmission with external data access devices. However, a significant trend is that the connector size is reduced but the telecommunications transmission volume is large. The speed and the density of conductive terminals have increased significantly, which has caused telecommunications to be more severely affected by electronic noise in the environment. Also, the surface of electronic cards when they are plugged in. ^ Static electricity will also affect the quality of telecommunications transmission. The card connector is provided with a ground structure electrically connected to the ground line of the motherboard to ensure the stability of telecommunication transmission. In addition, due to the difference between the height of the electronic card connector and the external plug interface, the industry mostly has a support frame at the lower end of the electronic card connector, and the support frame also has the function of heightening and grounding. For the conventional technology, please refer to US Pat.
