.~ And means to block access to power contact surface
DEFINITION
Classification: 439/93
And means to block access to power contact surface:
(under subclass 92) Electrical connector combined with (a) means to physically block the contact surface* thereof from electricity transmitting engagement with the contact surface of a cooperating connector; or, (b) a connector enclosing member having a portion intended to remain attached to the remainder of the enclosing member but repositionable to alternatively cover a contact surface or permit access to that contact surface.
(1) Note. The contact preventer of this subclass (clause a) includes any structure which, by disclosure, is intended to be used for that function and also any structure which is of like configuration but lacks specific disclosure of being a contact preventer; e.g.., a plastic shell intended to cover and protect the pins of an electron tube is included herein.
(2) Note. The retractable cover part of this subclass (clause b) is in addition to the electrical connector. Also the retractable cover part may, but is not required to, prevent making of electrical contact.
(3) Note. In this subclass, access is usually prevented to provide safety. The blocking means may be moved out to blocking position by insertion of the ground prong.
