Abstract

Abstract The rear pillars of an automobile body carry power and ground contact assemblies which engage contact plates of the electric rear window defogger when the lift gate is closed. The power and ground contact assemblies each consist of a plastic housing and a flat conductor strip which is stamped and bent to shape. The housings for both assemblies are identical. Both conductor strips comprise two elongated legs providing a depressible contact. The conductor strip for the power contact assembly has a terminal portion for connection to a power lead. The conductor strip for the ground contact assembly has a ground strap portion for connection to the pillar.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 320 words
A contact assembly for making an electrical connection to a contact plate carried by a movable closure panel when the closure panel is in the closed position comprising: a housing of dielectric material and a generally flat conductor strip stamped and bent to shape, said housing having a generally rectangular base having longitudinal edges, a front edge and a rear edge, a first upright side wall connected to a one longitudinal edge of the base, a second upright side wall connected to the opposite longitudinal edge of the base, a transverse tab which is part way up on the first side wall adjacent its front edge and which extends toward said second side wall, flange means at the front edge of each said side walls extending laterally outwardly away from each other, an upright lateral wall adjacent the rear edge of the base, an upright internal wall forming a narrow mounting slot in conjunction with the lateral wall and a fulcrum spaced from a rearward portion of the first side wall by a small gap, said conductor strip having first and second elongated legs connected at a bend, said first leg having a longitudinal stiffening rib and a rounded nose at the end thereof remote from the bend, said second leg having a transverse tab at the end thereof remote from said bend which is securely mounted in the narrow slot formed by the lateral wall and the internal wall of the housing, said conductor strip having a disengaged position where said first leg projects laterally beyond the flange means at the front edge of said first side wall and said second leg abuts the first side wall and passes between the lateral tab and the base, and said conductor strip being movable to a depressed position where said first leg is retracted substantially linearly by said second leg being flexed about the fulcrum away from the first side wall.
Claim 2
Dependent Claim 320 words
A contact assembly for making an electrical connection to a contact plate carried by a movable closure panel when the closure panel is in the closed position comprising: a housing of dielectric material and a generally flat conductor strip stamped and bent to shape, said housing having a generally rectangular base having longitudinal edges, a front edge and a rear edge, a first upright side wall connected to a one longitudinal edge of the base, a second upright side wall connected to the opposite longitudinal edge of the base, a transverse tab which is part way up on the first side wall adjacent its front edge and which extends toward said second side wall, flange means at the front edge of each said side walls extending laterally outwardly away from each other, an upright lateral wall adjacent the rear edge of the base, an upright internal wall forming a narrow mounting slot in conjunction with the lateral wall and a fulcrum spaced from a rearward portion of the first side wall by a small gap, said conductor strip having first and second elongated legs connected at a bend, said first leg having a longitudinal stiffening rib and a rounded nose at the end thereof remote from the bend, said second leg having a transverse tab at the end thereof remote from said bend which is securely mounted in the narrow slot formed by the lateral wall and the internal wall of the housing, said conductor strip having a disengaged position where said first leg projects laterally beyond the flange means at the front edge of said first side wall and said second leg abuts the first side wall and passes between the lateral tab and the base, and said conductor strip being movable to a depressed position where said first leg is retracted substantially linearly by said second leg being flexed about the fulcrum away from the first side wall.
Claim 3
Dependent Claim 369 words
A contact assembly for making an electrical connection to a contact plate carried by a movable closure panel when the closure panel is in the closed position comprising, a housing of dielectric material and a generally flat conductor strip stamped and bent to shape, said housing having a generally rectangular base having longitudinal edges, a front edge and a rear edge, a first upright side wall connected to one longitudinal edge of the base, a second upright side wall connected to the opposite longitudinal edge of the base, a transverse tab which is part way up on the first side wall adjacent its front edge and which extends toward said second side wall, a flange means at the front edge of each said side walls extending laterally outwardly away from each other, an upright lateral wall adjacent the rear edge of the base, a first upright internal wall forming a narrow rounded fulcrum spaced from a rearward portion of the first side wall by a small gap, a second upright internal wall forming a second narrow mounting slot in conjunction with the first upright internal wall, said conductor strip having first and second elongated legs connected at a bend, said first leg having a longitudinal stiffening rib and a rounded nose at the end thereof remote from said bend, said second leg having a transverse tab at the end thereof remote from said bend which is securely mounted in the narrow slot formed by the lateral wall and the internal wall of the housing, a terminal portion contiguous with the transverse tab at an end remote from said second leg, said terminal portion having a portion which is securely mounted in the second narrow slot formed by the first and second internal walls, said conductor strip having a disengaged position where said first leg projects laterally beyond the flange means at the front edge of said first side wall and said second leg abuts the first side wall and passes between the tab and the base, and said conductor strip being movable to a depressed position where said first leg is retracted substantially linearly by said second leg being flexed about the fulcrum away from the first side wall.
Claim 4
Dependent Claim 369 words
A contact assembly for making an electrical connection to a contact plate carried by a movable closure panel when the closure panel is in the closed position comprising, a housing of dielectric material and a generally flat conductor strip stamped and bent to shape, said housing having a generally rectangular base having longitudinal edges, a front edge and a rear edge, a first upright side wall connected to one longitudinal edge of the base, a second upright side wall connected to the opposite longitudinal edge of the base, a transverse tab which is part way up on the first side wall adjacent its front edge and which extends toward said second side wall, a flange means at the front edge of each said side walls extending laterally outwardly away from each other, an upright lateral wall adjacent the rear edge of the base, a first upright internal wall forming a narrow rounded fulcrum spaced from a rearward portion of the first side wall by a small gap, a second upright internal wall forming a second narrow mounting slot in conjunction with the first upright internal wall, said conductor strip having first and second elongated legs connected at a bend, said first leg having a longitudinal stiffening rib and a rounded nose at the end thereof remote from said bend, said second leg having a transverse tab at the end thereof remote from said bend which is securely mounted in the narrow slot formed by the lateral wall and the internal wall of the housing, a terminal portion contiguous with the transverse tab at an end remote from said second leg, said terminal portion having a portion which is securely mounted in the second narrow slot formed by the first and second internal walls, said conductor strip having a disengaged position where said first leg projects laterally beyond the flange means at the front edge of said first side wall and said second leg abuts the first side wall and passes between the tab and the base, and said conductor strip being movable to a depressed position where said first leg is retracted substantially linearly by said second leg being flexed about the fulcrum away from the first side wall.
