ELECTRICAL AND COMMUNICATION CONNECTION STRUCTURE OF A CABLE TRAY

摘要

The present invention provides a connection structure of an electricity and communication cable tray for stably connecting frames, which are connected at a determined angle by forming a coupling hole for connecting the frames to each other in a lengthwise direction. Also, the present invention provides an electricity and communication cable tray for preventing the deterioration of the coupling force of the connection member with the frames caused by the weight and vibration of a cable after the coupling of the frames by forming a V-shaped groove along the circumference of the coupling hole of the connection member. The connection structure of an electricity and communication cable tray according to the present invention comprises; a frame separated toward both sides and having multiple coupling holes formed therein; multiple hangers for connecting and supporting the frames; a connection member having coupling holes corresponding to the coupling holes of the frame to continuously arrange the frames in a lengthwise direction and connecting the adjacent frames to one another; and a ground bonding jumper having coupling holes coupled to the coupling holes formed on the frames on both side surfaces of the connection member and electrically connecting and grounding the frames. The coupling holes of the connection member are configured in a lengthwise direction, and a coupling member is coupled to the coupling holes formed in the lengthwise direction of the connection member to interconnect and fix the frames when the frame is connected at a determined angle.
