USB connectors developed in the mid-90s replaced the standard data connection and transfer interfaces of older board USB serial and parallel ports. Until today, many years later, USB connectors are still one of the most popular systems due to data connection and data transmission systems. USB connectors are powerful due to their convenient application, flexibility, compatibility and reliable power capability.
A USB connector has two basic parts:
1. Container: A USB receptacle is installed with a “female” connector in a host (such as a computer) or device (such as a digital camera or copier).
2. Plug: The USB plug is connected to the cable with the “male” connector.
Functional Characteristics of USB Connectors
1. Grip
Unlike other older connectors, USB keeps the clamping force of the socket in place for peripherals and cables. There are no thumb spins, screws or iron clips to keep it in place.
2. Durability
The improved design of the USB is more durable than the previous connector. This is because it is hot-swappable, allowing the feature of USB to add connectors to running computer software without significantly interrupting operation (ie shutting down or restarting the computer).
3. Maintenance Features
A closer look at the USB connector will reveal an adjacent plastic tongue and another closed metal tab that protects the entire connection and is additional maintenance for the USB. The USB plug also has a housing that touches the socket first before the pins are connected to the host. To shield the wires in the connector, grounding the shell is also good for static elimination.
4. The length is limited
While USB has these positive features and enhancements, the functionality of the data transfer interface is still limited. USB cables cannot connect peripherals and computers longer than 5 meters (or 16 inches 5 feet). Because they are designed to connect devices on separate desks, not between structures or rooms, USB connectors are limited in length. However, this can be solved by using self-powered USB by using a hub or active cable (repeater). USB can also implement bridge USB to increase cable length.
Despite these limitations, the USB connector is still the most powerful data transfer interface available today. USB anticipates connector upgrades to focus on improving transfer speeds, compatibility, and durability.
