Electrical cord locking connector

An electrical connector comprising:

• first and second electrical connecting devices, each having at least a pair of current-carrying conductors,
• said first device having an end provided with a plug having at least two prongs,
• said second device having an end provided with a socket having at least two openings therein for receiving corresponding prongs of said first device,
• said socket having a laterally outwardly projecting shoulder coextensive with said face for preventing improper mating of said prongs and openings, and
• said plug having a releasable latch member projecting therefrom and engaging said shoulder when the plug and socket are mated to prevent separation of the plug and socket during use.

A replacement cord cap assembly comprising:

• first and second electrical connecting devices, each having at least a pair of current-carrying conductive elements and a grounding conductor,
• said first device having an end presenting a plug having first and second prongs connected with respective current-carrying elements thereof, and a third prong connected with said grounding conductor thereof,
• said second device having an end provided with a socket presenting a generally circular face and having at least three openings therein for receiving corresponding prongs of said first device, a pair of said openings being presented by respective current-carrying elements of said second device,
• said socket having a laterally outwardly projecting shoulder coextensive with said face adjacent said pair of openings, and
• said plug having a releasable latch member projecting therefrom and engaging said shoulder when the plug and socket are mated, thereby preventing separation of the plug and socket under force until the latch member is disengaged.

An electrical cord locking connector comprising:

• first and second electrical cords, each having a pair of current-carrying conductors and a grounding conductor,
• said first cord having an end provided with a plug having at least three prongs, one of which is connected to the grounding conductor thereof,
• said second cord having an end provided with a socket having at least three openings therein for receiving corresponding prongs of said first cord,
• said socket having a generally circular face presenting said openings, and an outwardly projecting shoulder for preventing improper mating of said prongs and said openings,
• said plug having a releasable latch member projecting therefrom and engaging said shoulder when the plug and socket are properly mated to prevent separation of the plug and socket during use of the cords, and
• said shoulder projecting outwardly from said face between two of said openings connected to respective current-carrying conductors and from a side of said socket opposite said grounding connector.
