The implementation plan for the construction of the first batch of 7 national-level circular economy “Urban Minerals†demonstration bases has recently been approved by the National Development and Reform Commission and the Ministry of Finance. The Hunan Jurassic Recycling Resource Recycling Market and Processing Demonstration Base have successfully become one of the 7 demonstration bases. The first “urban mining area†in our province. In order to fully reflect the advanced concept of circular economy, green, low-carbon and energy-saving, the park's new high-rise road lighting, the park management executives have seriously discussed and decided to use the high-efficiency energy-saving LED street light lamps produced by Shenzhen Deshida Company. The procurement department of the park selected the lighting procurement network of Changsha Jiesheng Lighting Appliance Co., Ltd. as the supplier of LED street lamps through online procurement and bidding. During the scheduled time, the first batch of LED street light fixtures have been installed, fully achieving the expected energy-saving lighting effect. Garden-style circular economy demonstration base Adhering to the advanced concept of green, environmentally friendly, low-carbon and energy-saving, all road lighting in the park uses LED street lights. High-energy-saving LED street lights are installed on the roads in the production area of ​​the base. A comprehensive selection of USB connectors are available with various combinations of form factors, interface and version types, vertical and horizontal configurations, as well as a unique new USB 2.0 Type-C charging option.

USB (Universal Serial Bus) was originally developed and introduced in 1996 as a way of setting up communication between a computer and peripheral devices by replacing many varieties of serial and parallel ports.
USB connectors have become the standard connection method for devices such as mice, keyboards, game pads & joysticks, scanners, digital cameras, printers and external hard drives.
Although designed for personal computers USB has become commonplace on other devices such as mobile phones, PDA's, video game consoles, AC power adaptors, memory sticks and mobile internet access dongles.
USB Connector Type
USB Type A
Also known as USB standard A connector, the USB A connector is primarily be used on host controllers in computers and hubs. USB-A socket is designed to provide a "downstream" connection intended for host controllers and hubs, rarely implemented as an "upstream" connector on a peripheral device. This is because USB host will supply a 5V DC power on the VBUS pin. As such, it is important to remember while purchasing USB cables it is safest to make sure at least one of the plugs is a USB A.
Though not that common, USB A male to A male cables are used by some implementers to make connections between two USB A style female port. Be aware that typical A-A cables are not intended for connection between two host computers or computer to hub.

USB Type B
Also known as USB standard B connector, the B style connector is designed for USB peripherals, such as printer, upstream port on hub, or other larger peripheral devices. The primary reason for the development of USB B connectors were to allow the connection of peripheral devices without running the risk of connecting two host computers to one another. USB B type connector is still used today, though it is slowly being phased out in favor of more refined usb connector types.

USB Type C
USB-C or USB Type-C connector is the newest USB interface came to the market along with the new USB 3.1 standard. Different from previously mentioned USB A type and B type connector, USB C Type connector can be used on both host controller ports and devices which use upstream sockets. In the last few years a numbers of laptops and cellphones have appeared on the market with C style USB connectors.
USB Type C connector is compatible with USB 2.0, 3.0, 3.1 Gen 1 and Gen 2 signals. A full feature USB 3.1 Gen 2 C to C cable is able to transmit data at maximum 10 Gbps with enhanced power delivery of up to 20V, 5A (100W) and to support DisplayPort and HDMI alternate mode to transfer video and audio signal.

USB Mini B
Similar to USB B type connector, USB mini B sockets are used on USB peripheral devices, but in a smaller form factor. The mini B plug by default has 5 pins, including an extra ID pin to support USB On-The-Go (OTG), which allows mobile devices and other peripherals to act as a USB host.
Initially, this plug was designed for earlier models of smartphones, but as smartphones have become more compact and with sleeker profiles, the Mini USB plug has been replaced by the micro USB. Now, the Mini-B is designed for some digital cameras while the rest of the mini plugs series have become more of a legacy connectors as they are no longer certified for new products.
