Abstract
Abstract A female power contact assembly is provided for both parallel and tandem blades or any combination thereof. The assembly comprises two contact arms constituting a U-shaped contact for tandem blades, and a single contact arm riveted to one side of the U-shaped contact and constituting a second contact therewith for parallel blades. The single contact arm is part of a combination of a contact arm and binding plate.

Claim 2
Dependent Claim
104 words
A female contact spring assembly for use with straight-bladed male devices of either the tandem or parallel blade type comprising: first and second contact arms interconnected by a common base to constitute a U-shaped female contact for receiving a tandem male blade; a third contact arm connected to said common base and abutting one side of each of said first and second contact arms and cooperating therewith for receiving a parallel male blade; and means integral with said contact spring assembly arranged to be engaged by said first and second contact arms to restrict their deflection upon their receiving a tandem male blade therebetween.
Claim 3
Dependent Claim
152 words
A female contact spring assembly for use with straight-bladed male devices of either the tandem or parallel blade type comprising: a first contact comprising integral first and second contact arms interconnected by a common base and constituting a U-shaped female contact for receiving a tandem male blade; and a second contact comprising a third contact arm connected to said U-shaped contact and abutting one side of each of said first and second contact arms and cooperating therewith for receiving a parallel male blade; said common base includes an upright portion directed upwardly therefrom which, in turn, has portions projecting laterally therefrom to positions in which said projecting portions flank said first and second contact arms and are arranged to be engaged by said first and second contact arms to restrict the deflection of said first and second contact arms upon inserting a tandem male blade between said first and second contact arms.
Claim 4
Dependent Claim
152 words
A female contact spring assembly for use with straight-bladed male devices of either the tandem or parallel blade type comprising: a first contact comprising integral first and second contact arms interconnected by a common base and constituting a U-shaped female contact for receiving a tandem male blade; and a second contact comprising a third contact arm connected to said U-shaped contact and abutting one side of each of said first and second contact arms and cooperating therewith for receiving a parallel male blade; said common base includes an upright portion directed upwardly therefrom which, in turn, has portions projecting laterally therefrom to positions in which said projecting portions flank said first and second contact arms and are arranged to be engaged by said first and second contact arms to restrict the deflection of said first and second contact arms upon inserting a tandem male blade between said first and second contact arms.
Claim 5
Dependent Claim
18 words
The assembly as defined in claim 2 wherein said third contact arm is fixed to said upright portion.
Claim 6
Dependent Claim
18 words
The assembly as defined in claim 3, wherein said third contact arm is riveted to said upright portion.
Claim 7
Dependent Claim
22 words
The assembly as defined in claim 2, wherein said third contact arm includes a terminal portion having a binding screw attached thereto.
Claim 8
Dependent Claim
68 words
An electrical female connector device comprising a housing of electrical insulating material; a pair of female contact assemblies as defined in claim 2 mounted within said housing; and a pair of T-slots formed in said housing and oriented relative to said assemblies to permit selective insertion of either parallel or tandem male blades through said slots into saId housing into proper electrical engagement with said female contact assemblies.
Claim 9
Dependent Claim
101 words
A female contact spring assembly for use with straight-bladed male devices comprising: first and second contact arms interconnected by a common base to constitute a U-shaped female contact for receiving a straight male blade in one direction; a third contact arm connected to said common base and abutting one side of each of said first and second contact arms and cooperating therewith for receiving a straight male blade in one direction; and means integral with said contact spring axially arranged to be engaged by said first and second contact arms to restrict their deflection upon their receiving a male blade therebetween.
Claim 10
Dependent Claim
101 words
A female contact spring assembly for use with straight-bladed male devices comprising: first and second contact arms interconnected by a common base to constitute a U-shaped female contact for receiving a straight male blade in one direction; a third contact arm connected to said common base and abutting one side of each of said first and second contact arms and cooperating therewith for receiving a straight male blade in one direction; and means integral with said contact spring axially arranged to be engaged by said first and second contact arms to restrict their deflection upon their receiving a male blade therebetween.
