HARDENED POWER CABLE ADAPTERS AND RELATED ASSEMBLIESRelated Application (s)
[0001] The present application claims priority to and the benefit of U.S. Provisional Patent Application Serial No. 63 / 652, 306, filed May 28, 2024, the disclosures of which are hereby incorporated by reference herein in full.Field
[0002] The present invention relates generally to telecommunications equipment, and more particularly to, adapters for power cables and related assemblies.Background
[0003] Antenna towers are increasingly used in communications networks to provide cellular or other wireless devices. Remote radio heads (RRH) or remote radio units (RRU) coupled to or integrated with the antennas at the top of the towers transmit signals through the antennas. Typically, a feeder (or trunk) cable is routed up the tower to the RRH / RRU from a network base station at the bottom of the tower. The feeder cable carries transmission signals and optionally power between the base station and the RRH / RRU. FIG. 1A illustrates an example antenna tower site 10 in a communications network. The site 10 includes an antenna tower 20 at which one or more antennas 25 and one or more RRHs / RRUs 60 can be mounted and are adapted to transmit and receive signals to and from devices (e.g., mobile phones, smartphones, devices with wireless internet connectivity, etc. ) . In certain examples, the RRH / RRU 60 may be integrated into the antennas 25.
[0004] There are known connection interface assemblies suitable for use in managing cables on an antenna tower. For example, an adapter may be used to connect a power feeder or trunk cable to a power jumper cable to feed power to the cell tower antennas and / or RRHs / RRUs. Some power adapters include a conductor 73 which connects wires of the feeder or trunk power cable to wires of the power jumper cable. As shown in FIG. 1B, most conductors 73 use a plurality of set screws 71 to hold the wires of the trunk and jumper power cables. In most instances, the conductors are protected by one or more housing members to form a "hardened" power cable adapter. There may be a desire for alternative power connector / adapters for use in managing cables on an antenna tower.Summary
