Abstract

Abstract An electrical connector assembly including an elongate resilient synthetic resin channel member for attachment to a vehicle window, the channel member having therein a longitudinally extending channel of re-entrant cross-section. An elongate electrically conductive part is arranged to be received as a snap fit in said channel, whereby one or more conductive heating elements can be trapped between said part and the wall of said channel in electrical connection with said part. The channel member has a surface which supports said part within the channel in a position spaced from the base of the channel in a direction towards the open face of the channel.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 147 words
A window heater comprising: a plurality of heating elements for adhesive attachment to a transparent window member; an electrical connector assembly for one end of each of said heating elements, said electrical connector assembly including an elongated resilient synthetic resin channel member for attachment to said window, said channel member having therein a longitudinally extending channel of re-entrant cross-section, and an elongated electrically conductive part arranged to be received as a snap fit in said channel of said channel member so that said one end of each of said heating elements is trapped between said electrically conductive part and the wall of said channel in electrical connection with said electrically conductive part, said channel member including a surface which supports said electrically conductive part within said channel in a position spaced from the base of said channel in a direction towards the open face of said channel.
Claim 2
Dependent Claim 147 words
A window heater comprising: a plurality of heating elements for adhesive attachment to a transparent window member; an electrical connector assembly for one end of each of said heating elements, said electrical connector assembly including an elongated resilient synthetic resin channel member for attachment to said window, said channel member having therein a longitudinally extending channel of re-entrant cross-section, and an elongated electrically conductive part arranged to be received as a snap fit in said channel of said channel member so that said one end of each of said heating elements is trapped between said electrically conductive part and the wall of said channel in electrical connection with said electrically conductive part, said channel member including a surface which supports said electrically conductive part within said channel in a position spaced from the base of said channel in a direction towards the open face of said channel.
Claim 3
Dependent Claim 70 words
A window heater as claimed in claim 1 wherein said heating elements are in strip form having first and second ends, and further including a pair of said electrical connector assemblies, one of said electrical connector assemblies making electrical connection to one end of each of said heating elements and the other of said electrical connector assemblies making electrical connection to the other end of each of said heating elements.
Claim 4
Dependent Claim 45 words
A window heater as claimed in claim 1 wherein said surface is the upper surface of a rib extending along the length of the base of the channel and projecting upwardly towards the open face of the channel between the side walls of the channel.
Claim 5
Dependent Claim 33 words
A window heater as claimed in claim 1 wherein said surface extends at least in part laterally with respect to the depth direction of the channel from a side wall of the channel.
Claim 6
Dependent Claim 85 words
A window heater as claimed in claim 1 wherein said channel member includes a support section for attachment to the window and an upstanding wall section extending from said support section away from the window, said support section and said upstanding wall section defining a corner of said channel member, and further including a clamping member for attachment to at least one of said channel member and the window, said clamping member being arranged to overlie said heating elements in the region of said corner.
Claim 7
Dependent Claim 170 words
A window structure equipped with a heater, said window structure comprising: a transparent window member; a plurality of heating elements adhesively secured to said window member; and an electrical connector assembly for making electrical connection with one end of each of said heating elements, said electrical connector assembly including an elongated resilient synthetic resin channel member for attachment to said window member, said channel member having a longitudinally extending channel of re-entrant cross-section, said channel of re-entrant cross-section including a base portion and an open face spaced therefrom, and an elongated electrically conductive part arranged to be received as a snap fit in said channel so that said one end of said heating elements is trapped between said electrically conductive part and the wall of said channel in electrical connection with said electrically conductive part, said channel member including a surface which supports said electrically conductive part within said channel in a position spaced from said base of said channel in a direction towards said open face of said channel.
Claim 8
Dependent Claim 170 words
A window structure equipped with a heater, said window structure comprising: a transparent window member; a plurality of heating elements adhesively secured to said window member; and an electrical connector assembly for making electrical connection with one end of each of said heating elements, said electrical connector assembly including an elongated resilient synthetic resin channel member for attachment to said window member, said channel member having a longitudinally extending channel of re-entrant cross-section, said channel of re-entrant cross-section including a base portion and an open face spaced therefrom, and an elongated electrically conductive part arranged to be received as a snap fit in said channel so that said one end of said heating elements is trapped between said electrically conductive part and the wall of said channel in electrical connection with said electrically conductive part, said channel member including a surface which supports said electrically conductive part within said channel in a position spaced from said base of said channel in a direction towards said open face of said channel.
Claim 9
Dependent Claim 70 words
A window structure as claimed in claim 6 wherein said heating elements are in strip form having first and second ends, and further including a pair of said electrical connector assemblies, one of said electrical connector assemblies making electrical connection to one end of each of said heating elements and the other of said electrical connector assemblies making electrical connection to the other end of each of said heating elements.
Claim 10
Dependent Claim 45 words
A window structure as claimed in claim 6 wherein said surface is the upper surface of a rib extending along the length of the base of the channel and projecting upwardly towards the open face of the channel between the side walls of the channel.
Claim 11
Dependent Claim 33 words
A window structure as claimed in claim 6 wherein said surface extends at least in part laterally with respect to the depth direction of the channel from a side wall of the channel.
Claim 12
Dependent Claim 88 words
A window structure as claimed in claim 6 wherein said channel member includes a support section for attachment to said window member and an upstanding wall section extending from said support section away from said window member, said support section and said upstanding wall section defining a corner of said channel member, and further including a clamping member for attachment to at least one of said channel member and said window member, said clamping member being arranged to overlie said heating elements in the region of said corner.
