US 11,923,668 B2 · Splice for cable tray and cable tray assembly including same

Abstract

The present disclosure provides a cable tray assembly comprising a cable tray splice, first cable tray section, and second cable tray section adjacent the first cable tray section with both sections having a bottom wall. The cable tray splice couples to the bottom walls. The cable tray splice may include at least two fasteners and a splice body configured to engage adjacent cable tray sections. The fasteners are configured to couple the splice body to the adjacent cable tray sections and include a spring producing a biasing force against the splice body. The disclosure provides a method to form a cable tray assembly including positioning the two cable tray sections end-to-end, positioning a splice body on bottom walls of the two cable tray sections, inserting a fastener through aligned openings in the splice body and the bottom walls, and applying a spring biasing force to the splice body.

Dependent claims

A cable tray assembly comprising:

a first cable tray section including a bottom wall;
a second cable tray section adjacent the first cable tray and including a bottom wall defining a keyhole opening having a rectilinear portion and an enlarged rounded end portion;
a cable tray splice defining openings;
and
male twist-lock fasteners received in the respective keyhole openings of the first and second cable tray sections and the openings of the cable tray splice to couple the cable tray splice to the bottom walls of the first and second cable tray sections, whereby the first and second cable tray sections are spliced together to form the cable tray assembly, each of the male twist-lock fasteners comprising a stem body having upper and lower portions, wherein the upper portion of the stem body has opposite rounded longitudinal ends and opposite flat side ends, wherein the opposite rounded longitudinal ends are configured to fit snugly within the enlarged rounded end of the keyhole opening by rotating the stem body in the keyhole opening.

A cable tray splice for splicing together cable tray sections to form a cable tray assembly, the cable tray splice comprising:

a splice body configured to engage adjacent cable tray sections, wherein the splice body defines at least two keyhole openings, the keyhole openings each having a rectilinear portion and an enlarged rounded end portion;
and
at least two fasteners configured to be inserted into the respective at least two openings to couple the splice body to the adjacent cable tray sections, wherein each of the fasteners includes a spring producing a biasing force against the splice body to inhibit movement of the cable tray splice relative to the adjacent cable tray sections,
wherein each of the least two fasteners comprises a stem and a collar received on the stem and axially slidable along a length of the stem, the stem comprising a stem body having upper and lower portions, wherein the upper portion of the stem body has opposite rounded longitudinal ends and opposite flat side ends, wherein the opposite rounded longitudinal ends are configured to fit snugly within the enlarged rounded end of the keyhole opening as the stem is rotated in the keyhole opening.
