Opinions

Worley, Chief Judge.

This appeal is from the decision of the Board of Appeals affirming [1397]*1397tlie examiner’s rejection under 35 USC 103 of claim 3 1 as obvious to one of ordinary skill in the art in view of patents to Hedler2 and Matthysse.3

Plug-insert type wire connectors have long been known, particularly in the electrical utility field. These plug-inserts may take the form of parallel-sided plugs or more often wedges which are driven into corresponding connector housings containing one or more conductors. Use of such connectors soon revealed that when subjected to temperature variation, vibration and other environmental conditions, the conductors would often work loose thereby exposing the interior of the connection to corrosion and gradually reduce contact areas resulting in a poor connection, destructive arching [arcing?], and even pulling completely apart with the consequent danger to the community, of interruption of service and downed live wires. To overcome this disadvantage, screws, bolts, cotter pins, or the like, are often used in conjunction with solder or potting compounds to secure these connections. Thus, there has long existed a need for a simple, quick, inexpensive, and effective way to permanently lock and secure these otherwise highly desirable plug-insert type connections.

Appellants’ solution to that problem is reflected in process claim 3, road in conjunction with Figures 1, 2 and 4 of the drawings which show the parts utilized and the completed structure:
