socket connector

technical field

The utility model relates to a connector, in particular to a socket connector capable of reducing electromagnetic interference.

Background technique

Universal Serial Bus (Universal Serial Bus, USB) is the most popular for current electronic peripheral products (such as desktop computers, mobile computers, mobile communication devices or digital cameras, etc.) due to its convenience of plug and play and high transmission speed. A widely used transport interface.

With the advancement of technology, the transmission efficiency of the Universal Serial Bus has also been continuously improved (from USB1.1 to the current USB3.0 specification). One of the important reasons why the Universal Serial Bus is widely promoted is backward compatibility. In other words, the USB3.0 interface can be compatible with the old USB2.0 and USB1.1 devices, so as to greatly accelerate the popularity of USB3.0.

But relatively speaking, as the interface of the Universal Serial Bus is constantly updated and evolved, it will inevitably increase many signal terminals. For example, because the USB3.0 specification can be compatible with the old USB2.0 and USB1.1 devices, so , the USB3.0 specification must include signal terminals that are backward compatible with USB2.0 and USB1.1 in addition to the signal terminals of USB3.0 itself, and it is easy to generate electromagnetic interference between different signal terminals. And because the transmission rate of USB3.0 is greatly improved, the electromagnetic interference generated is also more serious.
