Embodiment Construction

[0041] Certain aspects and embodiments are directed to RF thermal fuses for preventing overheating of RF equipment receiving signals from base stations or other RF signal sources.

[0042] According to certain aspects, an RF thermal fuse can include a body, a conductive bolt, and a drive mechanism. The body may be placed on a transmission line (such as a coaxial cable) between an RF signal source (such as a base station) and an RF device (such as an antenna unit). The bolt may be threaded by or otherwise include a conductive material. The bolt may be placed within the body. The bolt may be of sufficient length to provide impedance at the point of protection in response to the bolt contacting a "live" conductor of the transmission line carrying the RF signal. Such as (but not limited to) the inner conductor of a coaxial cable. The impedance may be sufficient to feed back at least a portion of the incoming power of the RF signal from the RF signal source. The incident power,...

Abstract

Certain aspects are directed to a thermal fuse for preventing overheating of RF devices in a telecommunication system. The RF thermal fuse includes a body, a conductive bolt, and a driving mechanism. The body can be positioned on a transmission line between an RF signal source and an RF device. The conductive bolt is positioned in the body. The conductive bolt has a length sufficient to provide impedance at a point of protection on the transmission line in response to the conductive bolt contacting a live conductor of the transmission line. The impedance is sufficient to reflect a portion of the incident power of an RF signal from the RF source. The driving mechanism can cause the conductive bolt to contact the live conductor in response to a temperature at or near the point of protection axceeding a threshold temperature.

Description

[0001] Cross References to Related Applications [0002] This application requests U.S. Provisional Application Serial No. 61 / 637,632, filed April 24, 2012, entitled "RF Termination Device with Thermal Over-Temperature Protection Fuse," and filed October 9, 2012, titled Priority to US Provisional Application Serial No. 61 / 711,350 for "RF Thermal Fuse," the contents of both of which are incorporated herein by reference. technical field [0003] The present invention relates generally to telecommunications systems, and more particularly (but not necessarily exclusively) to thermal fuses for preventing overheating of RF equipment in telecommunications systems. Background technique [0004] Signal power received by telecommunication equipment in a telecommunication system can cause the temperature of the telecommunication equipment to increase. Telecommunications equipment may include cooling mechanisms to maintain the temperature of the internal components of the telecommunica...
