17-200321 Application Field and Working Principle

Theoretically, each type of connector can accept standard electrical signals, like USB, DVI, and HDMI. However, in different application fields, such as applications related to multimedia, electronics and computing, specific aspects of the connectors no longer meet the needs of the consumer or the industry, so specific adapters and connectors must be developed in order to solve practical problems.

USB

The USB (Universal Serial Bus) is a standard primarily used in computing and consumer electronics like keyboards, mice, scanners, printers, digital cameras, and many other peripherals. It provides a direct connection between two or more devices over a single port. Its main advantages are its speed, low power consumption, and support for plug and play. USB can transfer data at speeds of up to 480 Mbps, and is capable of supplying up to 500 mA of power.

In order to achieve the connection between devices, USB connectors hold two or more pins set in a specific order. Metal based connectors with a built-in locking mechanism are then used to ensure that they fit securely into each other. USB adapters are then used to cater to different types and sizes of devices. For example, an adapter may be used to connect a mouse to a smartphone or a USB Type A to a Type B.

DVI

The DVI (Digital Visual Interface) is a standard primarily used in computing and consumer electronics which connects computers to large displays or TVs. It uses a much higher voltage and wider physical connection than USB, and can provide up to 1920x 1200 resolution at 60 fps (digital) or 2048x 1536 resolution at 60 fps (analog).

The connectors used for DVI connection are thicker than USB connectors, and feature 10 to 23 pins arranged in three rows. They can also be adapted to version with a total of up to 27 pins. These connectors, with respect to the type of connection, may feature digital only or both digital and analog formats. Adapters are then used to adapt the cable to the type of device, such as VGA - DVI, FireWire - DVI, and DVI - HDMI.

HDMI

The HDMI (High Definition Multimedia Interface) is a standard primarily used in audio/video equipment like televisions, DVD players, gaming consoles, and digital projectors. It supports audio, analog video, and digital data and video. HDMI is capable of providing high resolutions, and fantastic color depth and contrast ratio performance.

In this case, the HDMI connectors feature either 19 or 29 pins. Adapters are able to convert from HDMI to DVI or vice-versa. They can also be combined with special cables to achieve maximum compatibility between highest-end devices.

Conclusion

USB, DVI, and HDMI connectors are the main standards in the field of electrical and digital data connection. Specifically designed 90 and 180 degree adapters and cables are then used to ensure a fast and reliable connection between different types of devices and equipment. To a certain extent, these connectors and adapters guarantee a level of compatibility between different types of devices and systems, ensuring that users and consumers are able to make the most out of their products.
