Description

Technical Field

[0001] The utility model relates to the technical field of data connectors, in particular to a USB connector with a switch. Background Art

[0002] With the development of the electronics industry, more and more electronic products have penetrated into people's daily life and work. USB connectors (such as data cables) as products for interconnection and communication of electronic products have been widely used by electronic product users. USB is the abbreviation of Universal Serial Bus in English. It is an external bus standard used to regulate the connection and communication between computers and external devices. USB is also a technical specification of input and output interfaces. It is widely used in information and communication products such as personal computers and mobile devices, and has been extended to other related fields such as photographic equipment, digital TVs (set-top boxes), and game consoles. The latest generation is USB3.1, with a transmission speed of 10Gbit / s, a three-stage voltage of 5V / 12V / 20V, and a maximum power supply of 100W. The new Type C plug type is no longer divided into positive and negative. USB, as a high-speed connection standard for computer peripherals, has been widely used in various external devices. In order to adapt to the development requirements of miniaturization and multifunctionality of electronic products, new USB connectors are constantly being launched. Mobile power is a portable charger designed with modern technology that can store electricity and is used in an emergency when mobile phones or other digital products need to be charged. Mobile power is generally electrically connected to digital products through USB connectors.

[0003] The USB connectors of the mobile power supplies currently on the market do not have the function of controlling charging and discharging, so the mobile power supplies must control the charging and discharging signals through analog signals. In other words, the USB male plug must be inserted into the USB connector first, and then the charging and discharging are controlled by analog signals. This increases the operation of using the mobile power supply, and when the USB male plug is in use, the USB connector cannot be opened and closed independently. Utility Model Content
