Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 196 words
A plug-in type of connector for a high voltage and high currect conductor, said connector comprising a first contact structure comprising a hollow member having a plurality of elongated spring finger contact members mounted therein to provide a hollow contact member, a second electrical contact member adapted to be plugged into said hollow contact member, said second electrical contact member having a member comprising arc-extinguishing material attached thereto, said member comprising arc-extinguishing material having a first cam shape surface at a first end thereof for engaging end portions of said spring finger contact members to open said spring finger contact members to facilitate insertion of said second contact member into the hollow provided by said spring finger contact members, means forming a second end of said member comprising arc extinguishing material to assist in opening said spring finger contact members to facilitate removal of said second contact member from said hollow contact structure provided by said spring contact members, and means causing said spring finger contact members to engage said second contact structure with a snap action when said second contact member is plugged into the hollow contact structure provided by said spring finger contact members.
Claim 2
Dependent Claim 196 words
A plug-in type of connector for a high voltage and high currect conductor, said connector comprising a first contact structure comprising a hollow member having a plurality of elongated spring finger contact members mounted therein to provide a hollow contact member, a second electrical contact member adapted to be plugged into said hollow contact member, said second electrical contact member having a member comprising arc-extinguishing material attached thereto, said member comprising arc-extinguishing material having a first cam shape surface at a first end thereof for engaging end portions of said spring finger contact members to open said spring finger contact members to facilitate insertion of said second contact member into the hollow provided by said spring finger contact members, means forming a second end of said member comprising arc extinguishing material to assist in opening said spring finger contact members to facilitate removal of said second contact member from said hollow contact structure provided by said spring contact members, and means causing said spring finger contact members to engage said second contact structure with a snap action when said second contact member is plugged into the hollow contact structure provided by said spring finger contact members.
Claim 3
Dependent Claim 50 words
The connector of claim 1 wherein said means to assist in opening said spring finger contact members to facilitate removal of said second contact member from said hollow provided by said spring contact members comprises a second cam shaped surface on a second end of said member comprising arc-extinguishing material.
Claim 4
Dependent Claim 70 words
The connector of claim 1 wherein said means causing said spring finger contact members to engage said second contact structure with a snap action when said second contact member is plugged into the hollow contact structure provided by said spring finger contact members comprises a second cam shaped surface on a second end of said member comprising arc extinguishing material and additional spring means acting on said spring finger contacts.
Claim 5
Dependent Claim 26 words
The connector of claim 3 wherein said additional spring means comprises a pair of tension springs connected to apply force to said spring finger contact members.
Claim 6
Dependent Claim 37 words
The connector of claim 3 wherein said additional spring means comprises a closed loop coil spring located in said hollow member and surrounding said spring finger contact members and applying force to said spring finger contact members.
