Description

Socket connector and plug connector

The present invention relates to a receptacle connector and plug connector that can increase the transmission of high frequency signals.

Different electronic devices are usually connected by signal transmission lines to transmit signals to each other. Currently, the signal transmission lines and electronic devices are detachably connected by a connector on one end of the transmission line and a connector socket on the electronic device. Among digital cameras, mobile phones, MP3s and other electronic products, the most popular signal transmission specification today is the Universal Serial Bus (USB). The miniature connector socket and transmission line made by this specification can reduce the number of cameras occupied by digital cameras. The size of electronic products such as mobile phones and MP3s is convenient for consumers to carry and use. At present, the commonly used micro universal serial bus (Micro USB) specification is multi-system version 2.0, and the theoretical transmission value can reach 480 Mbps.

However, the amount of software data for digital cameras, mobile phones, MP3s and other electronic products continues to rise, and the existing USB 2.0 has gradually lost the demand for high-traffic data transmission. China Video Electronics Industry Association announced a new signal transmission specification on April 29, 2009: DiiVA (DiiVA Digital Interface for Video and Audio), the signal transmission value can reach more than 10Gbps, enough to meet the needs of high-traffic data transmission. In order to be able to use on small electronic products such as digital cameras, mobile phones, and MP3s, the association plans to develop a small DiiVA interface, called Micro Diiva.

The Chinese utility model patent CN201397899Y announced on February 3, 2010 discloses a related socket and plug. However, the socket in the patent is not compatible with the Micro USB interface, and the portable products currently on the market are still USB. The connector is the mainstream configuration. In the short term, the USB interface is still widely used in various electronic products without any disappearance. In response to the demand for high-traffic transmission, future digital cameras, mobile phones, MP3 and other electronic products will also be included in the Micro Diiva interface. Sockets, therefore, in the near future, digital cameras such as digital cameras, mobile phones, and MP3s will have connector sockets that meet the above two specifications. However, the connector sockets of the above two interfaces are bound to increase the size of electronic products, and are not suitable for the development of miniaturization of electronic products.

Accordingly, the creators of the present invention conceived to design a socket compatible with the Mirco USB and Mirco DiiVa interfaces and a mating plug.
