Abstract
A control device having a housing provided with a terminal that has a threaded screw member with its shank threadedly carried thereby for lead attachment thereto between an enlarged head of the screw member and the terminal. A resilient retainer clip is disposed between the head of the screw member and the terminal, the clip initially being under compression between the head of the screw member and the terminal to tend to hold the screw member in its threaded relation with the terminal. A lead is subsequently disposed between the clip and the terminal, the clip thereafter being disposed in a deformed condition against the lead to hold the lead to the terminal. The clip has a plurality of slots in the deformable portion thereof to render the same more deformable.

In a control device having a housing provided with a terminal means having a threaded screw member with its shank threadedly carried thereby for lead attachment thereto between an enlarged head of the screw member and said terminal means, the improvement comprising a resilient retainer clip disposed between said head of said screw member and said terminal means, said clip having a portion provided with an opening therethrough and through which said shank of said screw member is telescopically disposed, a lead disposed between said portion of said clip and said terminal means, said portion of said clip being disposed in deformed condition against said lead by said head of said screw member to hold said lead to said terminal means, said clip having slot means passing through said portion thereof adjacent said opening to render said portion more deformable, said clip being in a substantially U-shape to define an initially bowed cross-member and a pair of legs thereof, said cross-member comprising said portion having said opening therethrough that telescopically receives said shank of said screw member, said legs of said U-shaped clip being disposed between said head of said screw member and said terminal means and being disposed on opposite sides of said shank of said screw member, said lead being disposed between one of said legs of said U-shaped clip and said shank of said screw member, said opening being substantially in the center of said cross-member and circular in configuration and said slot means comprising at least one slot that passes through said cross-member and being substantially trapezoidal in configuration with the smaller base thereof interconnecting with said opening and the larger base thereof being located at said one leg whereby said slot extends from said opening to said one leg and passes through said cross-member.
A resilient terminal clip for a control device having a housing provided with a terminal means having a threaded screw member with its shank threadedly carried thereby for lead attachment thereto between an enlarged head of the screw member and said terminal means, said clip being adapted to be disposed between said head of said screw member and said terminal means, said clip having a portion provided with an opening therethrough and through which said shank of said screw member is adapted to be telescopically disposed so that a lead is adapted to be disposed between said portion of said clip and said terminal means, said portion of said clip being adapted to be disposed in deformed condition against said lead by said head of said screw member to hold said lead to said terminal means, said clip having slot means passing through said portion thereof adjacent said opening to render said portion more deformable, said clip being in a substantially U-shape to define an initially bowed cross-member and a pair of legs thereof, said cross-member comprising said portion having said opening therethrough that is adapted to telescopically receive said shank of said screw member, said legs of said U-shaped clip being adapted to be disposed between said head of said screw member and said terminal means and disposed on opposite sides of said shank of said screw member whereby said lead is adapted to be disposed between one of said legs of said U-shaped clip and said shank of said screw member, said opening being substantially in the center of said cross-member and circular in configuration and said slot means comprising at least one slot that passes through said cross-member and being substantially trapezoidal in configuration with the smaller base thereof interconnecting with said opening and the larger base thereof being located at said one leg whereby said slot extends from said opening to said one leg and passes through said cross-member.
