DEFINITION

Classification: 439/693

With insulative covering about part of protruding portion of each contact:

(under subclass 692) Plug wherein each of the contacts protruding from the insulating body of the plug has an additional coating or sheath formed of insulating material which encloses or covers a part of the outwardly protruding portion of the contact.

(1) Note. Generally, the purpose of the insulative sheath covering a portion of the pronglike contacts is to prevent electrical shock to the person who may inadvertently grasp the pronglike contacts with his hand while plugging or

unplugging the plug into or from its mating receptacle.
