What is a USB connector?
Computer connectors are widely used in many scenarios, including
Overview
USB is popular due to its compatibility with numerous platforms and operating systems, low implementation costs, and ease of use. Connectors come in a variety of shapes and sizes with a variety of functions.
USB (Universal Serial Bus) is an industry standard developed in the 1990s for connections between computers and peripherals. USB is popular due to its compatibility with numerous platforms and operating systems, low implementation costs, and ease of use.
Usb-if (Universal Serial Bus Implemutors Forum, Inc.) is the support organization and forum for the advancement and adoption of USB technology. It was founded by the company that developed the USB specification and has more than 700 member companies. Current board members include Apple Inc., Hewlett-Packard Co., Intel Corp., Microsoft Corp., Renesas Electronics, ST and Texas Instruments.
Each USB connection is made using two connectors: an outlet (or socket) and a plug. The USB specification addresses the physical interfaces and protocols for device connectivity, data transmission, and power supply. USB connector types are represented by letters that indicate the physical shape of the connector (A, B, and C) and numbers that indicate the speed of data transfer (e.g. 2.0, 3.0, 4.0). The bigger the number, the faster the speed.
Specifications — Letters
USB A is thin and rectangular. It is probably the most common type and is used to connect laptops, desktops, media players, and game consoles. They are primarily used to allow host controllers or hub devices to provide data or power to smaller devices (peripherals and accessories).
USB B is square with a beveled top. It is used by printers and external hard drives to send data to host devices.
USB C is the latest type. It is small, has an elliptical shape and rotational symmetry (can be connected in either direction).
USB C transmits data and power over a single cable. It has been so widely accepted that the European Union will require its use for battery charging starting in 2024.
Specifications – Numbers
The original specification, USB 1.0 (12 Mb/s), was released in 1996, and USB 2.0 (480 Mb/s) in 2000. Both are suitable for USB Class A connectors.
With USB3.0, naming conventions become more complex.
USB 3.0 (5 Gb/s), also known as USB 3.1 Gen 1, came out in 2008. It is currently known as USB 3.2 Gen 1 and works with USB Type A and USB Type C connectors.
Introduced in 2014, USB 3.1 or USB 3.1 Gen 2 (10 Gb/s), currently known as USB 3.2 Gen 2 or USB 3.2 Gen 1×1, works with USB Type A and USB Type C.
USB 3.2 Gen 1 x 2 (10 Gb/s) for USB Type C. This is the most common specification for USB Type C connectors.
USB 3.2 (20 Gb/s) came out in 2017 and is currently known as USB 3.2 Gen 2×2. This applies to USB type C.
(USB 3.0 is also known as SuperSpeed.)
USB4 (usually without Spaces before 4) came out in 2019 and is widely available by 2021. The USB4 standard is up to 80 Gb/s, but currently its top speed is 40 Gb/s. USB 4 is suitable for USB type C.
