coupling (redirected from couplings)

coupling

1. a mechanical device that connects two things

2. a device for connecting railway cars or trucks together

3. the part of the body of a horse, dog, or other quadruped that lies between the forequarters and the hindquarters

4. Electronics the act or process of linking two or more circuits so that power can be transferred between them usually by mutual induction, as in a transformer, or by means of a capacitor or inductor common to both circuits

5. Physics an interaction between different properties of a system, such as a group of atoms or nuclei, or between two or more systems

6. Genetics the occurrence of two specified nonallelic genes from the same parent on the same chromosome

coupling [′kəp·liŋ]

(electricity)

A mutual relation between two circuits that permits energy transfer from one to another, through a wire, resistor, transformer, capacitor, or other device.

A hardware device used to make a temporary connection between two wires.

(engineering)

Any device that serves to connect the ends of adjacent parts, as railroad cars.

A metal collar with internal threads used to connect two sections of threaded pipe.

(mechanical engineering)

The mechanical fastening that connects shafts together for power transmission. Also known as shaft coupling.

coupling - The degree to which components depend on one another. There are two types of coupling, "tight" and "loose". Loose coupling is desirable for good software engineering but tight coupling may be necessary for maximum performance. Coupling is increased when the data exchanged between components becomes larger or more complex.
