Grounding connector
A grounding connector can include a connector body and a shear bolt. The connector body can have a recess sized to receive one or more conductors and a threaded portion. The shear bolt can be sized to engage the threaded portion of the connector body to secure the one or more conductors within the recess. When the shear bolt is tightened into the threaded portion of the connector body, the shear bolt can retain the one or more conductors within the recess. When the shear bolt is subject to a shear torque, a head of the shear bolt can shear from a body of the shear bolt. The shear torque can correspond to a target compression force applied between the shear bolt and the one or more conductors.
1 . A grounding connector assembly, comprising:
a connector body that includes a recess extending in an axial direction from a blind end, and an internal thread extending in the axial direction, the connector body defining a first cross-sectional profile taken perpendicular to the axial direction, the first cross-sectional profile being a first hexagonal profile, the recess opening to a lateral side of the connector body, relative to the axial direction, to define a lay-in entrance to receive one or more conductors into the recess in an insertion direction that is transverse to the axial direction; and
a shear bolt engaged with the internal thread of the connector body in axial alignment with the recess, to be threadedly movable into the recess to engage the one or more conductors;
the shear bolt having a shear torque at which a hexagonal head of the shear bolt is configured to shear from a body of the shear bolt, the shear torque corresponding to a target compression force between the shear bolt and the one or more conductors when the shear bolt is tightened into the internal thread of the connector body so that the body of the shear bolt retains the one or more conductors at the blind end of the recess.
2 . The grounding connector assembly of claim 1 , wherein the recess is formed as a slot that extends into the connector body and includes: a first portion that extends parallel to the axial direction, a bend, and a second portion that extends laterally from the bend to the lateral side of the connector body and the lay-in entrance.
3 . The grounding connector assembly of claim 2 , wherein the slot is intersected by the internal thread and exhibits a first width that is smaller than an inner diameter of the internal thread.
4 . The grounding connector assembly of claim 3 , wherein the slot extends axially away from the lay-in entrance past an axial end of the internal thread.
5 . The grounding connector assembly of claim 1 , wherein the connector body integrally includes a conductor portion that at least partly includes the recess and an overhang portion that is on an axially opposite side of the lay-in entrance than is the conductor portion.
6 . The grounding connector assembly of claim 5 , wherein the overhang portion includes the internal thread.
7 . The grounding connector assembly of claim 6 , wherein the internal thread of the overhang portion extends over an axial length to secure the shear bolt to the connector body in a staged orientation, in which the shear bolt is oriented to permit the one or more conductors to be inserted into or removed from the recess via the lay-in entrance.
8 . The grounding connector assembly of claim 7 , wherein conductor portion also includes the internal thread.
9 . The ground connector assembly of claim 5 , wherein, a cross-sectional profile of the overhang portion, taken perpendicular to the axial direction, is substantially identical to a cross-sectional profile of the conductor portion, taken perpendicular to the axial direction.
10 . The grounding connector assembly of claim 1 , wherein the connector body defines a second cross-sectional profile taken perpendicular to the axial direction, the second cross-sectional profile being a circular profile and being located axially between the first hexagonal profile and the hexagonal head of the shear bolt.
11 . The grounding connector assembly of claim 1 , wherein the shear bolt further includes a cap between the body and the hexagonal head, the cap extending laterally by farther than the internal thread to provide a stop against over-insertion of the shear bolt into the recess.
12 . The grounding connector assembly of claim 1 , wherein the connector body is secured to a grounding rod that extends axially from the connector body in an opposite direction than the shear bolt.
13 . The grounding connector assembly of claim 12 , wherein the connector body is threadedly connected to the grounding rod.
14 . A grounding connector assembly, comprising:
a grounding rod;
a connector body engaged at a first end with the grounding rod and including, at a second end, a threaded portion extending in an axial direction, and a recess sized to receive one or more conductors, the recess opening out of the connector body in a lateral direction, relative to the axial direction; and
a shear bolt engaged with the threaded portion of the connector body to secure the one or more conductors within the recess, a head of the shear bolt being configured to shear from a body of the shear bolt at a target compression force between the shear bolt and the one or more conductors to retain the one or more conductors within the recess.
15 . The grounding connector assembly of claim 14 , wherein the recess is formed as a slot that extends into the connector body, including: a first portion that extends parallel to the axial direction to define slot openings at opposing lateral sides of the connector body; and a second portion that extends laterally from the first portion to a lay-in entrance.
16 . The grounding connector assembly of claim 14 , wherein the connector body exhibits a circular cross-section along the recess and a hexagonal cross-section at an end axially opposite from the head of the shear bolt.
17 . The grounding connector assembly of claim 14 , wherein the recess defines a lay-in opening in the lateral direction to receive the one or more conductors; and
wherein the second end of the connector body extends axially past the lay-in opening and includes at least part of the threaded portion.
18 . The grounding connector assembly of claim 17 , wherein the threaded portion at the second end of the connector body is cantilevered to be in axial alignment with the recess.
19 . A method of establishing a grounding connection, the method comprising:
providing a connector body that includes a recess extending in an axial direction from a blind end, and an internal thread extending in the axial direction, at least a portion of the connector body defining a hexagonal cross-sectional profile, taken perpendicular to the axial direction, the recess opening to a lateral side of the connector body, relative to the axial direction, to define a lay-in entrance;

tightening a shear bolt into the internal threads of the connector body, including by engaging the shear bolt and the hexagonal cross-sectional profile of the connector body, to threadedly move the shear bolt in the axial direction to engage the one or more conductors within the recess; and
further tightening the shear bolt to a shear torque, to shear a head of the shear bolt from a body of the shear bolt, the shear torque corresponding to a target compression force between the shear bolt and the one or more conductors so that the body of the shear bolt retains the one or more conductors at the blind end of the recess.
20 . The method of claim 19 , wherein the shear bolt is retained by the internal thread of the connector body as the one or more conductors are inserted into the lay-in entrance.
