Abstract
Range taking shear bolts and bolt installation (drive) tools are described herein, which are configured for use with a variety of range taking connectors and conductors.
Claims23
A range taking shear bolt system, comprising:
- a range taking shear bolt;
- and
- a drive tool for installing the range taking shear bolt in a range taking connector,
- the range taking shear bolt comprising:
- a hollow body comprising a wall having an outer surface and an inner surface;
- a
- distal end constructed and arranged to abut a cable conductor;
- and a
- proximal end constructed and arranged to accept the drive tool,
- the inner surface having a non-round shape configured to engage with the drive tool and including one or more internal grooves substantially perpendicular to the longitudinal axis of the bolt, the one or more internal grooves defining one or more shear zones where the wall is configured to shear when an applied torque reaches or exceeds a predetermined torque value, and
- the outer surface having a screw thread configured to engage with a threaded opening on the connector and including one or more longitudinal grooves in the thread along a longitudinal axis of the bolt and/or one or more external grooves substantially perpendicular to longitudinal axis of the bolt, each external groove aligned with a corresponding internal groove;
- and
- the drive tool comprising:
- an inner portion comprising a head portion and a drive portion;
- and an outer portion comprising a tubular body,
- the head portion including a hexagonal drive or a square drive configured to accept a socket or impact wrench,
- the drive portion having a non-round shape configured to fit inside the body of the range taking shear bolt and engage with the inner surface thereof, and
- the tubular body configured to fit over the body of the range taking shear bolt and abut the connector to control a depth of tool insertion.

A range taking shear bolt system comprising:
- a range taking shear bolt;
- and
- a drive tool for installing the range taking shear bolt in a range taking connector,
- wherein the range taking shear bolt comprises:
- a hollow body defined by a wall having an outer surface and an inner surface,
- the inner surface having a non-round shape configured to engage with the drive tool and including a plurality of V-shaped internal grooves substantially perpendicular to a longitudinal axis of the range taking shear bolt, the plurality of V-shaped internal grooves being dispersed along a length of the hollow body and a tip of each of the plurality of V-shaped internal grooves defining a potential shear point where the wall is configured to shear when an applied torque reaches or exceeds a predetermined torque value,
- the outer surface having a continuous screw thread configured to engage with a threaded opening on the range taking connector;
- a distal end configured to abut a cable conductor inside the range taking connector;
- and
- a proximal end configured to accept the drive tool;
- and
- the drive tool comprising:
- an inner portion having a head portion, a distal end portion, and a drive portion, the drive portion having a non-round shape configured to be accepted by the proximal end of the range taking shear bolt and engage with the inner surface of the hollow body, the distal end portion being located below the drive portion, the distal end portion having a diameter that is less than a diameter of the drive portion and configured to be a pilot for entry into the hollow body of the range taking shear bolt;
- and
- an outer portion having a tubular body, the tubular body configured to fit over the hollow body of the range taking shear bolt and abut the range taking connector to control a depth of insertion of the drive tool,
- wherein, in response to the applied torque from the drive tool reaching or exceeding the predetermined torque value, the hollow body of the range taking shear bolt shears at one of the plurality of V-shaped internal grooves, the one of the plurality of V-shaped internal grooves at which the shearing takes place is independent of a depth of insertion of the inner portion of the drive tool within the hollow body of the range taking shear bolt.
