USB connectors are often overlooked and taken for granted, but they can be a huge pain to try and replace if you have the wrong kind. This post will go over all of the different types of USB connectors that exist today.
Different Types of USB Connectors
USB Type A
The Type A connector is one of the most popular USB connectors. It has a rectangular shape when viewed from above and can be used in both host-to-peripheral or peripheral-to-host configurations. The plug housing on this type of connector accommodates 22 pins that provide for two data lines, four address lines, plus power and ground connections.
USB Type B
The type B has a rectangular shape and is designed for use in small devices that don’t require much power or many capabilities like keyboards or mice. In addition to providing data transfer features similar to those on the A connector, it also provides two extra contact pins and an ID pin.
These allow peripherals of this type to be uniquely identified by their host computers so they can act accordingly when multiple devices are connected simultaneously. This makes it ideal for low-power applications such as wireless mouse dongles which may not always have line of sight with the receiver unit but still need some identification capability without draining battery life unnecessarily.
USB Type C
The newest type of USB is the “Type-C” plug, sometimes referred to as a Micro B connector. This new design came about because many people were having issues with their cables and plugs due to frequent use over time or improper insertion that caused wear on the pins in older models.
The Type-A end has an open top so it can be plugged into devices from either direction while also being more symmetrical than previous designs. It provides power connections like the types A and B connectors but does not have data lines built into it which makes for faster charging times when used with compatible devices. Internal cables may require adapters at each end such as one made by Belkin that converts from a Mini-B to a Type-C.
USB Mini B
The MiniB connector is an older design that was originally used for small peripherals like keyboards and mice, as well as other devices with low power requirements. It has since been replaced in most cases by the MicroB or A connectors although they are still available on some products from time to time.
One of its biggest advantages over the newer designs is that it can be plugged into a device without removing any protective caps which makes them easier to use when you’re plugging something in behind furniture or another object where visibility may not be great. The downside to this is that there’s no protection against dust particles getting inside through those unprotected openings so these plugs should only be used where visual inspection is possible.
USB Micro B
The MicroB connector is a variation of the Mini-B design that was designed to be used on devices such as cell phones and tablets which require high power for their operating systems or additional features like wireless connections.
The plug housing accommodates 20 pins, three data lines, plus ground and power contacts not available in some smaller designs but it doesn’t have ID pins so peripherals can only be identified by proximity detection rather than having any way to identify them when multiple devices are connected at once.
This type has largely been replaced now with newer versions of USB connectors due to its limitations although they may still appear on older products because replacement cables might involve higher costs depending on availability compared with a cheaper Mini-B cable.
