Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
162 words
A two prong electrical connector for connecting electrical apparatus to a two conductor electrical outlet comprising, on insulating housing of two seperatable halves, a terminal prong mounted in and extending respectively from each half of said housing and to which may be electrically connected said apparatus and with the longitudinal axis of said terminal prongs positioned substantially parellel with each other when said connector halves are secured together, means forming at least one pair of arms extending form one half of said housing, arm receiving surfaces formed in the other half of said housing and with said arms and arm receiving surfaces positioned to engage and releasably secure said connector halves together by movement of said connector halves together in a direction substantually transverse to the longitudinal axis of said terminal prongs and to prevent seperation of said connector halves except by movement of said connector halves apart along a plane lying substantially transverse to the longitudinal axis of said terminal prongs.
Claim 2
Dependent Claim
162 words
A two prong electrical connector for connecting electrical apparatus to a two conductor electrical outlet comprising, on insulating housing of two seperatable halves, a terminal prong mounted in and extending respectively from each half of said housing and to which may be electrically connected said apparatus and with the longitudinal axis of said terminal prongs positioned substantially parellel with each other when said connector halves are secured together, means forming at least one pair of arms extending form one half of said housing, arm receiving surfaces formed in the other half of said housing and with said arms and arm receiving surfaces positioned to engage and releasably secure said connector halves together by movement of said connector halves together in a direction substantually transverse to the longitudinal axis of said terminal prongs and to prevent seperation of said connector halves except by movement of said connector halves apart along a plane lying substantially transverse to the longitudinal axis of said terminal prongs.
Claim 3
Dependent Claim
36 words
An electrical connector as claimed in 1 wherein said apparatus is an string of series connected ornamental lights of which the terminal ends of said series are respectively connected to the terminal prongs of said connector.
Claim 4
Dependent Claim
24 words
An electrical connector as claimed in claim 2 wherein the connector halves are formed as moldings about the respective terminal ends of said series.
Claim 5
Dependent Claim
25 words
An electrical connector as claimed in claim 1 wherein said arms and arm receiving surfaces includes means for releasably locking the said connector halves together.
Claim 6
Dependent Claim
46 words
An electrical connector as claimed in claim 1 wherein each half of the said housing includes respective recesses into which may be inserted the terminal prongs of a similar type connector for respectively engaging electrically a poriton of the said terminal prongs within said connector halves.
