Abstract

Abstract The stabs on a busbar for mechanically and electrically receiving circuit breakers, or the like, are shaped so as to have two mutually perpendicular contact plug-in elements on a single stab enabling the single stab to receive circuit breaker contacts that are oriented in mutually perpendicular directions.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 121 words
A bus bar contact stab structure formed integrally from a single sheet of conductive material, said structure including an elongated bus bar section located in a first plane and a stab unit section laterally offset from the longitudinal axis of said bus bar section, said stab unit section including a planar central stab portion bent forward out of said first plane into a plane perpendicular thereto and perpendicular to said axis, said stab unit central section also including first and second planar side stabs in a first common plane perpendicular to said first plane and parallel to said axis, said side stabs positioned on opposite sides of the central stab portion and extending the same distance forward of the first plane.
Claim 2
Dependent Claim 121 words
A bus bar contact stab structure formed integrally from a single sheet of conductive material, said structure including an elongated bus bar section located in a first plane and a stab unit section laterally offset from the longitudinal axis of said bus bar section, said stab unit section including a planar central stab portion bent forward out of said first plane into a plane perpendicular thereto and perpendicular to said axis, said stab unit central section also including first and second planar side stabs in a first common plane perpendicular to said first plane and parallel to said axis, said side stabs positioned on opposite sides of the central stab portion and extending the same distance forward of the first plane.
Claim 3
Dependent Claim 45 words
A bus bar contact stab structure as set forth in claim 1 also including a connecting section interposed between said bus bar section and said stab unit section, a first of said side stabs being connected directly to said connecting section and extending forward therefrom.
Claim 4
Dependent Claim 64 words
A bus bar contact stab structure as set forth in claim 1 also including a connecting section interposed between said bus bar section and said stab unit section, said first side stab being connected directly to said connecting section and extending forward therefrom, said second side stab being connected directly to said central stab portion, said side stabs being forward of said first plane.
Claim 5
Dependent Claim 50 words
A bus bar contact stab structure as set forth in claim 3 in which the first side stab is bent forward from the connecting portion and the latter is in said first plane, said second side stab being bent from said central stab portion away from said first side stab.
Claim 6
Dependent Claim 43 words
A bus bar contact stab structure as set forth in claim 1 in which the central stab portion extends more forward than the side stabs and includes a stab section that is closer to the bus bar section then are the side stabs.
Claim 7
Dependent Claim 87 words
A bus bar contact stab structure as set forth in claim 1 in which the stab unit section also includes third and fourth planar side stabs positioned in a second common plane parallel to the first common plane and extending forward of the first plane the same distance as the first and second side stabs, and first and third side stabs positioned on one side of the central stab section and the second and fourth side stabs are on the other side of the central stab section.
Claim 8
Dependent Claim 45 words
A bus bar contact stab structure as set forth in claim 6 also including a connecting section interposed between said bus bar section and said stab unit section, said first and third side stabs being connected directly to said connecting section and extending forward therefrom.
Claim 9
Dependent Claim 33 words
A bus bar contact stab structure as set forth in claim 7 in which the second and fourth side stabs are bent from said central portion away from the first and third stabs.
Claim 10
Dependent Claim 43 words
A bus bar contact stab structure as set forth in claim 8 in which the central stab portion extends more forward than the side stabs and includes a stab section that is closer to the bus bar section then are the side stabs.
Claim 11
Dependent Claim 59 words
A bus bar contact stab structure as set forth in claim 1 also including another stab unit section of identical construction as the stab unit section, said stab unit sections being spaced along the length of the bus bar section with the central stab portions of the stab unit sections being aligned and equally spaced from the longitudinal axis.
