Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
115 words
In a connector assembly for making solderless in-line, pigtail or tap electrical connection between insulated wires and comprising a base having parallel longitudinal wire-supporting channels and being grooved transversely of said channels, and a resilient slotted metal plate contact element fitting within a said groove and with slots in alignment with said wire-supporting channels, the improvement comprising a resiliently displaceable stop member extending from a wall of said channel and blocking said channel between an outermost groove and the adjacent end of the channel, and said base being recessed to provide an open space adjacent said stop member for receiving said stop member upon its displacement under forceful insertion of a wire into said channel.
Claim 2
Dependent Claim
115 words
In a connector assembly for making solderless in-line, pigtail or tap electrical connection between insulated wires and comprising a base having parallel longitudinal wire-supporting channels and being grooved transversely of said channels, and a resilient slotted metal plate contact element fitting within a said groove and with slots in alignment with said wire-supporting channels, the improvement comprising a resiliently displaceable stop member extending from a wall of said channel and blocking said channel between an outermost groove and the adjacent end of the channel, and said base being recessed to provide an open space adjacent said stop member for receiving said stop member upon its displacement under forceful insertion of a wire into said channel.
Claim 3
Dependent Claim
23 words
Connector of claim 1 wherein said stop member extends inwardly from a wall of said channel and generally perpendicular to the axis thereof.
Claim 4
Dependent Claim
22 words
Connector of claim 2 wherein said wire-supporting channels are open-faced and said stop member extends from the bottom of a said channel.
Claim 5
Dependent Claim
30 words
Connector of claim 2 wherein at least one of said wire-supporting channels is in part defined by a hinged side wall and said stop member extends from said side wall.
Claim 6
Dependent Claim
19 words
Connector of claim 1 wheRein are included two of said stop members, one near each end of said channel.
Claim 7
Dependent Claim
28 words
Connector of claim 1 wherein said stop member extends from an end wall of said body into, and at an acute angle with the axis of, said channel.
Claim 8
Dependent Claim
19 words
Connector of claim 6 wherein are included two of said stop members, one near each end of said channel.
