Abstract
A conductor terminal clamp using a screw to maintain in tight overlapping relation an electric cable and the flat conductor end. The clamp collar is constructed without the use of welds and is provided with a pair of opposing movable finger members. The terminal end is disposed within the collar between the movable finger members which apply a gripping force transversely upon the terminal end as the screw applies the clamping force perpendicularly upon the overlapping collar and conductor end.
Claims28
In combination with a circuit interrupter that has a housing of insulating material and is adapted to protect an electric circuit from current overloads,
- a bus conductor extending from said housing, and
- a collar assembly fastened to said bus conductor for facilitating the connection of said circuit interrupter to an electric cable conductor that comprises part of said circuit being protected,
- said collar assembly comprising:
- a collar having a first leg and a second leg;
- securing means associated with said collar for applying a first securing force upon the electric cable conductor for urging the electric cable conductor into electrical contact with said bus conductor and for securing the electric cable conductor within said collar;
- and
- a movable portion connected to said first leg and extending toward said second leg for moving in cooperation with said securing means as said securing means is operated to apply said first securing force for attenuating a stress said first securing force generates upon said collar.
In combination with a circuit interrupter that has a housing of insulating material and is adapted to protect an electric circuit from current overloads,
- a bus conductor extending from said housing, and
- a collar assembly fastened to said bus conductor for facilitating the connection of said circuit interrupter to an electric cable conductor that comprises part of said circuit being protected,
- said collar assembly comprising:
- a collar having a first side and a second side;
- securing means associated with said collar for applying a first securing force upon the electric cable conductor for urging the electric cable conductor into electrical contact with said bus conductor and for securing the electric cable conductor within said collar;
- and
- a first movable portion connected to said first side and extending toward said second side for moving in cooperation with said securing means as said securing means is operated to apply said first securing force for applying a second securing force upon said bus conductor, said second securing force being applied in a direction differently than the direction of said first securing force, for securing said bus conductor within said collar when said securing means is operated to apply said first securing force.
An electrical conductor clamping device, comprising:
- a collar having a first side and a second side;
- securing means associated with said collar for applying a securing force upon an electrical conductor disposed within said collar;
- a first flange connected to said first side and extending toward said second side;
- and
- a second flange connected to said second side and extending toward said first side, said first and second flanges being cooperable with respect to each other for attenuating a mechanical stress the securing force generates upon said collar.
An electrical conductor clamping device, comprising:
- a collar having a first side and a second side;
- securing means associated with said collar for applying a first securing force upon an electrical conductor disposed within said collar;
- and
- a movable finger member attached to said first side and extending toward said second side for applying a second securing force upon the electrical conductor disposed within said collar, said second securing force being applied in a direction differently than the direction of said first securing force.
An electrical conductor clamping device comprising:
- a collar having a first side and a second side;
- securing means associated with said collar for applying a first securing force upon an electrical conductor disposed within said collar;
- a first finger member attached to said first side and extending toward said second side for applying a second securing force upon the electrical conductor disposed within said collar;
- and
- a second finger member attached to said second side and extending toward said first side for cooperating with said first finger member in applying said second securing force upon the electrical conductor.
