Cable tray assembly
A cable tray assembly includes first and second cable tray sections each including a base and rails extending transversely from longitudinal sides of the base. At least one of the base and the rails defines a plurality of holes. A splice plate is configured to engage the first and second cable tray sections for attaching the first cable tray section to the second cable tray section. The splice plate defines a plurality of holes. At least one snap-fit connector includes a head and a plurality of resiliently deflectable arms extending from the head. The arms of the connector are configured to extend through aligned holes in the splice plate and one of the cable tray sections to secure the splice plate to said one of the cable tray sections.
1. A cable tray assembly comprising:
a cable tray section including a base and rails extending transversely from longitudinal sides of the base, at least one of the rails including a retainer projecting laterally on the rail;
a splice plate configured to engage the retainer on the cable tray section such that the splice plate is retained to the cable tray section by the retainer; and
a connector configured to attach the splice plate to the cable tray section;
wherein the retainer comprises a first flange extending laterally from a top of said at least one of the rails at a downward angle, and a second flange extending laterally from a bottom of said at least one of the rails at an upward angle toward the first flange forming a dovetail shaped channel extending along an exterior of said at least one of the rails.
2. The assembly set forth in claim 1 , wherein the flanges extend along an entire length of said at least one of the rails.
3. The assembly set forth in claim 1 , wherein the connector comprises a thread-type fastener for coupling an additional component to the cable tray assembly when the splice plate is attached to the cable tray section.
4. The assembly set forth in claim 1 , wherein the splice plate has a trapezoidal shape configured to be received in the dovetail shaped channel to retain the splice plate to the cable tray section.
