Abstract
Abstract A double insulated plug includes a preformed housing of insulating material. The plug contacts and corresponding conductors of a cord are electrically and mechanically joined to form connections. The connections are received in the preformed insert in spaced-apart relationship with the insert substantially encasing the connections. A body of insulating material is molded around the insert and the connections.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
131 words
A wiring device comprising: a preformed insert of insulating material, said insert including a base, a pair of sidewalls and an end wall extending from the base; an intermediate wall extending from said base and joined to said end wall; said intermediate wall being spaced from said sidewalls to form a recess between said intermediate wall and each of said sidewalls respectively; an electrical cord having a pair of power conductors; a pair of power contacts; each of said power contacts being mechanically and electrically connected to a corresponding one of said power conductors to form a pair of power connections; each of said power connections being received in a corresponding recess; and a body of insulating material molded around said insert and substantially fills said recesses around said power connections.
Claim 2
Dependent Claim
