A bus coupler is a device which is used to couple one bus to the other without any interruption in power supply and without creating hazardous arcs. A bus coupler is a breaker used to couple two busbars to perform maintenance on other circuit breakers associated with that busbar. It is achieved with the help of a circuit breaker and isolators.
Both ends of the bus, whether it includes one coupler or a series of couplers connected together, must be terminated (in accordance with MIL-STD-1553B) with "a resistance, equal to the selected cable nominal characteristic impedance (Zo) ± 2.0 percent."

This difference is reflected in the bus connectors used, in that USB cables are asymmetrical (one end Type A, other end Type B) while FireWire cables may have identical connectors at both ends. The more-recent USB-C cables may also have identical connectors on both ends (in which case the logical A and B ends are negotiated between the attached ...
An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...

The diagram from Beard's 1897 coupler patent [1]. Janney couplers were first patented in 1873 by Eli H. Janney (U.S. patent 138,405). [2] [3] Andrew Jackson Beard was amongst various inventors that made a multitude of improvements to the knuckle coupler; [1] Beard's patents were U.S. patent 594,059 granted 23 November 1897, which then sold for approximately $50,000, and U.S. patent 624,901 ...
