Abstract
Various implementations of grounding clamps and torque-controlled fasteners are disclosed. The grounding clamps may be used to attach grounding conductors to various structures, such as pipes, conduit, grounding rods etc. The torque-controlled fasteners may use various techniques to control the amount of torque applied to the fasteners used with the grounding clamps described herein.
Claims14
A grounding clamp, comprising:
- a clamp including an upper jaw and a lower jaw rotatable about a pivot point at respective first ends and biased in a closed position by a spring, the upper jaw and the lower jaw each having a respective concave second end opposite the first end, the concave second ends of the upper jaw and the lower jaw forming a recess;
- a torque-controlled fastener extending through the upper jaw and at least partially through the lower jaw, wherein the torque-controlled fastener is configured to control a predetermined amount of force applied by the upper jaw and the lower jaw, by rotation of the upper jaw and the lower jaw about the pivot point.
A grounding clamp, comprising:
- an upper jaw and a lower jaw rotatable about a pivot point at respective first ends and biased in a closed position by a spring, the upper jaw and the lower jaw each having a respective concave second end opposite the first end, the concave second ends of the upper jaw and the lower jaw forming a recess;
- a fastener extending through the upper jaw and at least partially through the lower jaw, the fastener configured to adjust an amount of force applied by the upper jaw and the lower jaw, by rotation of the upper jaw and the lower jaw about the pivot point.
A torque-controlled fastener, comprising:
- a threaded portion including a first set of angled teeth;
- a driving mechanism including a second set of angled teeth, the driving mechanism to loosen and tighten the threaded screw by applying a torque to the threaded screw;
- and
- a compression spring biasing the driving mechanism against a head of the threaded portion such that the first set of angled teeth mates with the second set of angled teeth,
- wherein the second set of angled teeth slips against the first set of angled teeth when the torque applied to the threaded portion by the driving mechanism exceeds a specified amount of torque.
