Abstract
Abstract A terminal connector for conducting electrical current from a source of power to a resistance heating element. The connector comprises a flexible braided conductor with a terminal at one end for attachment to a power source and a spring clamp attached to the other end to intimately clamp the conductor directly against a resistance heating element and maintain the intimate contact as the heating element expands and contracts with changes in its temperature.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
103 words
An electrical heating element connector comprising a clip member having a generally cylindrical resilient portion, a connector member having tab portions to connect a flexible conductor to said cylindrical portion of the said clip member, and a flexible electrical conductor, said conductor being formed of a plurality of conductive strands and having a substantially greater width than thickness, one end of said conductor being positioned within said cylindrical portion, said conductor extending over one end of said clip along the outside of said cylindrical portion, and said conductor being fixedly held against said clip member by said tab portions of the connector member.
Claim 2
Dependent Claim
103 words
An electrical heating element connector comprising a clip member having a generally cylindrical resilient portion, a connector member having tab portions to connect a flexible conductor to said cylindrical portion of the said clip member, and a flexible electrical conductor, said conductor being formed of a plurality of conductive strands and having a substantially greater width than thickness, one end of said conductor being positioned within said cylindrical portion, said conductor extending over one end of said clip along the outside of said cylindrical portion, and said conductor being fixedly held against said clip member by said tab portions of the connector member.
Claim 3
Dependent Claim
61 words
A heating element electrical connector as defined in claim 1 wherein: said connector member includes a substantially flat base, said tab portions projecting outwardly from opposite edges of said base and extending across said base toward each other, said tab portions ends being spaced from each other and from said base, said conductor extending between said tab portions and said base.
Claim 4
Dependent Claim
31 words
An electrical heating element connector as defined in claim 1 wherein: said generally cylindrical portion is provided with flaring lip portions thereby providing a smooth entrant for an object forced therebetween.
Claim 5
Dependent Claim
101 words
An electrical connection between a cylindrical rod heating element and a multiple strand conductor comprising: a biasing clip having a generally cylindrical resilient portion, a connector member having tab portions to connect a flexible conductor to said cylindrical portion of the said clip member, said tabs being bent in a direction away from said cylindrical portion, and a flexible electrical conductor comprising, a substantially flAt strap one end of which extends within said tab portions and is clampingly retained thereby and also within said generally cylindrical portion for electrically conductive attachment by said biasing clip to said cylindrical rod heating element.
Claim 6
Dependent Claim
101 words
An electrical connection between a cylindrical rod heating element and a multiple strand conductor comprising: a biasing clip having a generally cylindrical resilient portion, a connector member having tab portions to connect a flexible conductor to said cylindrical portion of the said clip member, said tabs being bent in a direction away from said cylindrical portion, and a flexible electrical conductor comprising, a substantially flAt strap one end of which extends within said tab portions and is clampingly retained thereby and also within said generally cylindrical portion for electrically conductive attachment by said biasing clip to said cylindrical rod heating element.
Claim 7
Dependent Claim
40 words
An electrical connector as defined in claim 4 wherein: said conductor is formed of a plurality of conductive strands and having a substantially greater width than thickness, one end of said conductor being bent and positioned within said cylindrical portion.
Claim 8
Dependent Claim
61 words
An electrical connector as defined in claim 4 wherein: said connector member includes a substantially flat base, said tab portions projecting outwardly from opposite edges of said base and extending across said base toward each other, the ends of said tab portions being spaced from each other and from said base, said conductor extending between said tab portions and said base.
Claim 9
Dependent Claim
110 words
An electrical connection between a cylindrical rod heating element and a multiple strand conductor comprising: a biasing clip having a generally cylindrical resistant portion, said generally cylindrical portion being provided with flaring lip portions thereby providing a smooth entrant front for an object forced therebetween, a connector member having tab portions to connect a flexible conductor to said cylindrical portion of the said clip member, and a flexible electrical conductor comprising, a substantially flat strap one end of which extends within said tab portions and is clampingly retained thereby and also within said generally cylindrical portion for electrically conductive attachment by said biasing clip to said cylindrical rod heating element.
Claim 10
Dependent Claim
110 words
An electrical connection between a cylindrical rod heating element and a multiple strand conductor comprising: a biasing clip having a generally cylindrical resistant portion, said generally cylindrical portion being provided with flaring lip portions thereby providing a smooth entrant front for an object forced therebetween, a connector member having tab portions to connect a flexible conductor to said cylindrical portion of the said clip member, and a flexible electrical conductor comprising, a substantially flat strap one end of which extends within said tab portions and is clampingly retained thereby and also within said generally cylindrical portion for electrically conductive attachment by said biasing clip to said cylindrical rod heating element.
