ABSTRACT:
A tamperproof handset for use in a railroad communication system. The handset has a cable provided with plural wires which electrically connect the handset with a communication control. The control is provided with a housing having a front panel. The cable extends through a passage in a male connector section having a key section, a swaged section and a slotted section. The slotted section is provided with an annular slot. A female connector section has a slotted section and a threaded section. The male key section matingly engages the female slotted section. The threaded section of the female connector is threadedly secured to the front panel within a threaded hole in the front panel. A "C" shaped retainer is frictionally secured to the male slotted section to prevent displacement of the male connector section with respect to the female connector section. A jam nut is threadedly secured to the female connector threaded section and contacts the control housing to prevent rotation of the threaded section. The cable is surrounded by a neoprene sleeve section which is deformed within the passage in the male connector section to prevent withdrawal of the sleeve section and cable from the male connector section.
