technical field

The utility model relates to the technical field of connectors, in particular to a USB3.1 connector. The utility model also relates to a male end and a female end of a USB3.1 connector.

Background technique

USB3.1 is the latest USB specification, and the data transmission speed can be increased to a speed of 10Gbps. USB3.1 includes three types, Type-A, Type-B and Type-C. The biggest feature of USB3.1 Type-C is that although the size of the opening is as small as the standard Micro-B connector for Android smartphones and tablet computers, it supports a maximum data transmission speed of 10Gbit/s. Type-C supports the "USBPowerDeliverySpecification (USBPD)" which improves the power supply capability compared to the past. USB PD has five levels of specifications: 10W, 18W, 36W, 60W, and 100W, according to the available power. The Type-C connector supports 100W (20V, 5A) power supply. Type-C also takes a lot of steps to improve ease of use. For example, it supports the "reverse insertion" function that can be inserted from both sides, and the introduction of a function that notifies the user with a sound when the connector is inserted whether it has been inserted correctly. Because USB3.1 Type-C has the advantages of small size, fast transmission speed, and reversible insertion, it is more and more used in electronic equipment.
