DEFINITION

Classification: 439/135

WITH CONTACT PREVENTER OR RETRACTABLE COVER PART:

(under the class definition) Electrical connector combined with (a) means to physically block the contact-surface* of the device 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 connector but repositionable to alternatively cover a contact-surface or permit access to that contact-surface.

(1)

The contact preventer of this subclass (clause a) includes any structure which, by disclosure, is intended to be used for that function. Also any structure which is of like configuration but lacks specific disclosure of intent to cover and protect the plane of electron tube is included herein (specifically, in subclass 150) intended hereunder.

(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.
