A Dock connector is a connector used to attach a mobile electronic device simultaneously to multiple external resources. The Dock connector will typically carry a variety of signals and power, through a single connector, to simplify the docking process of the mobile device. A dock connector may be integrated into a mechanical device used to support or align the mobile device or may be at the end of a cable. The dock connector was originally associated with laptops, but other mobile devices use the concept.
Anchor connectors for laptops are typically integrated into a mechanical device that supports and aligns the laptop and that has various single-function ports and a power source that are aggregated into the docking connector. The anchor connectors would carry interfaces such as keyboard, serial, parallel, and video ports on the laptop and provide power.
Many mobile devices have a dock connector. The dock connector can be used to interface accessories such as external speakers, including stereo systems and clock radios. Automotive accessories for mobile devices include charging cradles, FM transmitters to play audio through the car speakers and a GPS receiver. There are dock connection cables that offer additional capabilities such as direct integration with the car’s audio system and controls.
Apple’s proprietary 30-pin connector was common to most Apple mobile devices (iPhone (1st generation), iPhone 3G, iPhone 3GS, iPhone 4, iPhone 4S, 1st generation iPod Touch, iPad 2, iPad 2 and iPad 3 ). introduction with the 3rd generation iPod classic in 2003 until the release of the Lightning connector in late 2012. Originally, Apple’s Dock connector was equipped with USB ports, FireWire, some controls and level audio outputs line. As the iPod has changed, the signals in the dock connector have changed. The video has been added to the connector. FireWire was removed from iPods, which led to a discontinuity in the use of the dock connector. Due to the popularity of Apple’s iPod and iPhone devices using the connector, a cottage industry has been created from third-party devices that can connect to the interface. With the discontinuation of the sixth generation iPod Classic and the iPhone 4S, the latest Apple products equipped with the original 30-pin connector, the connector was also removed in September 2014.
Apple introduced an 8-pin Dock connector, named Lightning, on September 12, 2012. iPhone 5 and later, iPod touch 5th generation and later, seventh-generation iPod nano, every iPad mini, iPad (4th generation) and later, and iPad Pro all use the Lightning connector, just like several Apple accessories. The pins on the Apple Lightning connector are accessible from both sides of the connector, allowing insertion from each side upwards. The Lightning connector replaced the 30-pin dock connector used by previous generations of iPods, iPhones, and iPads.
The Samsung Galaxy Tab and Galaxy Note 30-pin dock / charge connector is very similar to the non-proprietary PDMI connector, although it is not identical to this one. It is not tied to the 30-pin Apple connector.
The 2001 edition of the Korean Telecommunications Technology Association (TTA) “Digital Cellular Phone I / O Interface Standard” has defined a 24-pin electromechanical interface for cell phone charging, cable data transmission , analog audio, etc. 20 pins but added composite video output support among other changes.
The Portable Digital Multimedia Interface (PDMI) is a 30-pin interconnect standard for portable media players. It was developed by the Consumer Electronics Association as ANSI / CEA-2017-A, Common Interconnection for Portable Media Players in February 2010. The standard was developed with the input or support of more than fifty consumer electronics in the world.
