Structural improvement of electrical connectors

The invention provides an improvement of the structure of the electrical connector, in particular, the card seat structure is sleeved on the plug portion of the circuit board, and the elastic arm of the metal piece of the card seat structure contacts the ground end of the plurality of metal contacts of the plug portion And the pins of the metal piece are in contact with the circuit board to form a common grounding circuit, which can effectively block the electromagnetic wave interference generated when the high frequency signal of the adjacent metal contacts is transmitted.

According to the rapid development of electronic technology, the type of computer has evolved from a desktop computer to a small, portable notebook computer, and it is widely used in various corners of the society when users want to transmit data signals or When connecting with other peripheral devices, the so-called peripheral device interface is required, and the peripheral device interface on the market is the most common and widely used by the public. The general-purpose serial bus (USB) is still used as the mainstream, and USB support is used. Hot-swappable features are plug-and-play and easier to use.

Moreover, today USB3.0 has become the most popular mainstream connection interface, and is fully utilized in various external electronic products, such as external hard disk drives, solid state hard drives, DVD players, etc., and facing other high-speed interfaces. The challenge is to introduce the USB3.1 Type-C specification, which is slightly larger in size than the existing USB2.0 Mirco-B, supports higher power charging and power supply capabilities, and can be up to 10Gbps in transmission speed.
