Coaxial cable fitting

Abstract

A specially configured 'tee' fitting for tapping into a coaxial cable network is disclosed. The fitting includes a conductive block having a cylindrical channel extending between aligned first and second openings and a passage extending between a third opening and the channel at a right angle to the channel. Cylindrical insulators are fitted into the channel at the openings, and each insulator has a central aperture for receiving the ends of a conductive double-ended pin unit. A central region of the pin unit extends between the first and second end regions, the end regions each having a coaxial blind hole. A coaxial cable connector assembly component includes a nipple adapted to be threaded into the passage and an outwardly directed coaxial cable connector which extends through by the nipple. The cable connector assembly also includes an inwardly directed spring biased center pin which is connected to the inner conductor coupling components of the coaxial cable connector and bears, at its outboard end, against the double-ended pin unit. The system bus is coupled across the fitting by providing permanent securance (as by crimping a crimp ring) to the abutting bus coaxial cable ends in such a manner that the center conductors of the cable ends extend into the blind holes and their outer conductors are placed in electrical contact with the block. Upon abandonment of a station, the entire cable connector assembly may be removed from the fitting and replaced with a threaded cap-off plug.
