    摘要： In a mating plug and socket assembly one prong of the plug has a light and photocell associated with it when it is in place in the socket so that light is transmitted to the photocell thereby indicating that the plug and socket are mated. This photocell controls a relay having contacts in series between the electrical source and the socket so as to only close the circuit to the socket when the plug and socket are so mated. There are various arrangements of the light and photocell in conjunction with the one prong and the socket.

    摘要： An electrical receptacle having a power energized safety-lock to prevent insertion, or withdrawal, of a second component such as a receptacle cover, or a plug for connection therewith, while the receptacle is energized. Energy for urging a plug-engaging finger into a lock position in which it can obstruct the movement of the plug in or out of the receptacle is provided by a strong spring. However, only a small amount of energy is required to maintain, or lock the plug-engaging finger in this lock position when, as in accordance with this invention, a boltlike obstruction is moved to block the release-motion of the plug-engaging finger. The bolt is moved to its lock position by a solenoid which is energized in parallel with the receptacle contacts.
