In Electronics , deciding Which Of Two Mating Connectors is the plug and which the '''socket''' is sometimes arbitrary. In general:

The male connector is the plug, the female the '''socket'''. This may pose a problem if both connectors have some male and female characteristics, for example the XLR3 .

The connector possessing the pins is the plug, the other the '''socket'''. This may pose a problem if both connectors have pins, for example the European 3-pin Power Connector .

The connector normally mounted on a cable is the plug, and the connector mounted on the equipment is the '''socket'''. See DC Plug for an example of this usage. This may pose a problem if the usage changes with time.

There are also hermaphrodite connectors, see Electrical Connector .
