A multifunctional connector

technical field

The invention relates to the technical field of signal connectors, in particular to a multifunctional connector.

Background technique

Signal connectors are electronic devices that connect two or more electronic devices for signal exchange and transmission, and are widely used in electronic information products. Nowadays, the use of electronic information products is quite common, and the connection relationship between electronic information products is mainly realized by connectors. The electrical connector usually has a plurality of conductive terminals, and is electrically connected with the welding terminals on the circuit board, so as to realize the transmission of electrical signals.

High Definition Multimedia Interface (HDMI) is a digital video/audio interface technology. It is a dedicated digital interface suitable for image transmission. It can transmit audio and video signals at the same time. The maximum data transmission speed is 4.95Gb /s, without the need for digital/analog or analog/digital conversion before signal transmission. At present, HDMI has a wide range of applications in the fields of home appliances and PCs due to its advantages of supporting audio and video output and providing enough bandwidth to play 1080p high-definition programs. The connector of the HDMI1.4 version generally has nineteen pins, four of which are pins for data signal transmission, two for each group, and four groups of eight pins in total. There are also three pins dedicated to control, these control signals include DDC (Display Data Channel ) and consumer electronics control (Consumer Electronics Control, CEC ). The rest are non-data signal transmission pins, such as signal interference shielding pins, power pins, grounding pins, etc.

USB3.0 is developed on the basis of USB2.0, which has a higher data transmission speed than USB2.0, and is currently used in many new electronic devices. The USB3.0 interface adds five pins to the original USB2.0 interface.

MHL (MOBILE HIGH-DEFINITION LINK) is also called mobile high-definition. MHL can be applied to mobile phones, PDAs, digital cameras, digital video cameras, portable digital players and other devices. MHL is a new type of video transmission protocol for portable products jointly initiated by a number of electronic product manufacturers. MHL can not only provide high-definition audio and video signals, but also has a low operating current, and is increasingly favored by manufacturers of electronic information products.

Micro-USB connector is a signal connector that is smaller and more space-saving than standard USB and Mini-USB connectors. At present, most digital products such as mobile phones and MP4s on the market have such connector sockets. Micro-USB In addition to being used for data transmission, it can also be used as a charging plug.

However, whether it is an HDMI connector, a USB3.0 connector, or an MHL connector, each has its own specific structure. With more and more types and functions of electronic information products, there is currently no standard connector that unifies the functions of HDMI, USB3. A multi-functional connector with all the above functions, and supports the widely used Micro-USB plug. the
