The present disclosure relates to systems and methods of locking a faulted circuit indicator (FCI). For example, the FCI may include a locking assembly. The locking assembly may include a lock plate that selectively moves between a locked position and an unlocked position. When in the locked position, the lock plate blocks a lock link of the FCI from moving in a first direction to prevent the FCI from opening. When in an unlocked position, the lock plate enables the lock link of the FCI to move in the first direction to allow the FCI to open.

An antenna detent and latching mechanism for use in a radiotelephone to provide a robust connection of an antenna to the radiotelephone. When the mechanism and antenna are coupled, the antenna can be rotated from a stored position to one of two deployed positions.

Antenna detent and latching mechanism for a radiotelephone

An antenna coupling system including an antenna stem (108) with a raised wall (206) having an opening (210) therethrough and defining a plurality of key receptacles (216, 218, 220, 222) and detents (224, 410, 412) coupled to an antenna latch detent mechanism (102) that provides a manner of maintaining a SSU antenna (106) in a stowed position and two deployed positions with respect to the SSU handset (100). The antenna coupling system further includes an antenna connector (110) and a handset connector (104) wherein rotation of the antenna connector (110) with respect to the handset connector (104) maintains a robust RF connection and notifies circuitry in the handset (100) when the antenna (106) is in one of two deployed positions.

Housing for a two-way radio repeater

A radio assembly (100) includes a radio chassis (120) and radio housing (150). The radio chassis (120) includes a resilient cantilever arm (130) having an engaging portion (135). The radio housing (150) includes a mount channel (156) to position the cantilever arm (130), and a ramped catch portion (157) within the mount channel (156) to engage the engaging portion (135) of the cantilever arm (130) and to secure the radio chassis (120) within the radio housing (150). The chassis (120) is mounted to the radio housing (150) such that the engaging portion (135) of the cantilever arm (130) is positioned within the mount channel (156). The engaging portion (135) of the cantilever arm (130) is biasedly engaged with the ramped catch portion (157), and is deflectable so as to disengage from the ramped catch portion (157) when a deflecting force is applied to the engaging portion (135). A radio disassembly tool (300) disassembles the radio assembly (100) by deflecting and releasing the engaging portion (135) of the cantilever arm (130) from the ramped catch portion (157).
