主权项

1. A torque controlling break screw for securing a wire or cable within a connector, the torque controlling break screw comprising:
a threaded, thin-walled screw body; a nut secured at a distal end of the screw body; a torque limiting feature which keeps the nut secured at the distal end of the screw body; wherein the screw and nut combination are screwed into an aperture within the connector until the screw contacts a conductor housed within the connector body; wherein when a force is applied to the nut which exceeds the strength of the torque limiting feature, it causes the nut to break loose from the distal end of the screw by overcoming the torque limiting feature so that it can travel down the length of the screw body until it contacts the connector; and wherein when an even greater force is applied to the nut when in contact with the connector body, it exceeds the shear strength of the screw body and causes the excess length of the screw body to be sheared off such that the remaining screw is flush with the surface of the connector.
