Description

Technical Field:

[0001] The utility model relates to the technical field of connector products, in particular to an economical Type-C connector. Background Art:

[0002] USB is the abbreviation of Universal Serial BUS, and its Chinese abbreviation is "universal serial line". It is an external bus standard used to standardize the connection and communication between a computer and external devices. It is an interface technology applied in the PC field. USB was jointly proposed by multiple companies such as Intel, Compaq, IBM, and Microsoft at the end of 1994. USB not only has a fast transmission speed but is also very convenient to use. The USB interface also has the advantages of supporting plug-and-play and hot-plugging functions of devices, flexible connection, independent power supply, etc. It can be connected to a mouse, keyboard, printer, scanner, camera, flash drive, MP3 player, mobile phone, digital camera, external hard drive, external optical or floppy drive, USB network card, ADSL Modem, Cable Modem, etc. Almost all external devices are equipped with a USB interface and are very widely used. Type-C is a connection interface of the USB interface. It can be inserted regardless of the front or back. Its size is approximately 8.3mm × 2.5mm, and like other interfaces, it supports functions such as USB-standard charging, data transmission, and display output. Type-C connectors are mainly for thinner and more slender devices, enhancing usability and paving the way for performance enhancements in future USB versions.

[0003] Currently, a standard Type-C connector uses 24 terminals for conducting electricity or transmitting signals. Among them, the upper end surface of the tongue plate of the insulating seat in the Type-C connector is provided with contact parts for 12 terminals, and the lower end surface of the tongue plate is also provided with contact parts for 12 terminals.
