SET SCREW CONNECTOR WITH ANTI-BACKOUT LOCK
First Claim
1. An electrical connector configured to couple an electrical conductor to a support surface of an electrical device, the electrical connector comprising:
- a terminal block including a connecting aperture, a threaded aperture, and a lock aperture, the connecting aperture configured to receive the electrical conductor, the lock aperture having an opening providing communication between the lock aperture and the threaded aperture;
a locking fastener including threads to be receivable within the threaded aperture, the locking fastener configured to move in a first rotational direction to secure the electrical conductor against movement relative to the terminal block, the locking fastener configured to move in a second rotational direction to release the electrical conductor from the terminal block; and
a lock including a shaft defining a longitudinal axis, the lock receivable within the lock aperture of the terminal block and moveable along the longitudinal axis, the lock moveable between a first position and a second position, when the lock is in the first position, the lock permits movement of the locking fastener in the second rotational direction, when the lock is in the second position, a surface of the shaft contacts the locking fastener to inhibit movement of the locking fastener in the second rotational direction.

Abstract
An electrical connector is configured to couple an electrical conductor to a support surface of an electrical device. The electrical connector includes a terminal block having a connecting aperture and a threaded aperture. The connecting aperture is configured to receive the electrical conductor. The electrical connector includes a locking fastener having threads to be receivable within the threaded aperture. The locking fastener is configured to move in a first rotational direction to secure the electrical conductor against movement relative to the terminal block. The locking fastener is configured to move in a second rotational direction to release the electrical conductor from the terminal block. The electrical connector includes a lock engaging the locking fastener in a locked position to inhibit movement of the locking fastener in the second direction. The lock disengages the locking fastener in an unlocked position to permit movement of the locking fastener in the second direction.
