AI Technical Summary

Benefits of technology

The invention relates to an electronic device with a mechanism for preventing damage caused by electrostatic discharge (ESD). It involves setting a spring plate on top of the main bearing plate where it connects to a data card interface. This allows ESD to pass through the spring plate to the data card's interface without affecting its function or performance. By doing this, the grounding loop becomes longer and improves grounding efficiency.

Problems solved by technology

This patent describes how grounding performance in an electronics device can affect its EMC characteristics. It explains that when connecting two devices together by way of a USB connection, there are different ways for it to behave differently depending on which part of the device's hardware is being used. One method involves using a specialized metal plate called a USB connector or sliding flexible disk. Another method uses a specific type of material called a deck bearing plate. These technical means help improve the overall quality of the signal transmitted across the connectors.

Embodiment Construction

The following describes a sliding expansion data card provided in an embodiment of the present invention with reference to the accompanying drawing.

The FIGURE shows a structure of a sliding expansion data card in an embodiment of the present invention. The following describes the sliding expansion data card taking that the data card interface is a USB interface as an example. The data card includes a USB interface 101, a spring plate 102, and a main bearing plate 103, and a shield 104. The USB interface 101 is set at one end of the main bearing plate 103. The shield 104 is located on the lower surface of the main bearing plate 103. One end of the spring plate 102 is set on the shield 104 and the other end of the spring plate 102 contacts the USB interface 101.

One end of the spring plate may be fixed beside the shield 104 which is located on the lower surface of the main bearing plate 103 at the data card interface side. When the USB interface 101 is connected with an external device, t
