Abstract: A unidirectional insert lock for securing an insert, with a central mounting hole, to a pocket in a cutting tool is provided. The insert lock includes a locking pin having an eccentric and a radially extending lobe, and a shim having an arcuate channel angularly bordered by a first and second stop, that is configured to receive the lobe. The locking pin is inserted through holes in both the insert and the shim so that when the lobe is rotated in one direction the eccentric urges the insert into a secured cutting position within the pocket. However, when the lobe is rotated in the opposite direction the second stop prevents the pin from sufficiently rotating so that the eccentric is not able to urge the insert against the sides of the pocket, and consequently, the insert sits loosely in the pocket so that it is clear to the operator that the insert is not secured in the cutting position.

Abstract: An energy transmission cable connector for connecting terminals in a circuit has a cable coupled to a connector housing which is enclosed by a molded outer housing. The outer housing has a pair of side cavities pivotally receiving a pair of latches. The latches have locking fingers for engaging a connecting element and are biased into a locking position by integral leaf springs or helical compression springs. The pivotal coupling of the latches is accomplished by protrusions on the latches retained by recesses in the housing, a pin assembly, or an integrally molded hinge. The connector can be used with electrical or fiber optic cables.

Also, a manual adjustment screw is located perpendicular to the axis of rotation of the cartridge for applying an adjustment force to the cartridge in opposition to the action of the torsion leaf spring. The torsion leaf spring applies a pre-load force to the cartridge. The manual adjustment screw exerts an opposing force that rotates the cartridge to a desired position for proper orientation of the associated cutter insert.
