Abstract
Abstract A coaxial connector is described, of the type that has a shell (14, FIG. 1 ) with a tubular first portion (16) whose front mates with another connector and whose extreme rear end (64) is initially open, and which has a second portion (22) extending at a right angle to the first portion for mechanically and electrically terminating to the braiding (42A) of a coaxial cable (30). The second portion (22) of the shell forms a tubular ferrule that surrounds the cable inner insulation (40) and which is surrounded by the cable braiding. The connector includes a sleeve (46) which can slide along the cable to a position surrounding the braiding that surrounds the ferrule, so crimping of the sleeve locks the braiding between the ferrule and sleeve. The shell second portion includes first and second parts (50, 52) that extend respectively from the lower and upper sides (60, 62) of the rearward end (56) of the first shell portion, with the second part being bendable and each part forming about half of the tubular ferrule. The second part (52) extends rearwardly from the upper side of the shell first portion while lying above the mate axis (12) of the first shell portion to provide access for a soldering iron to reach into the initially open rear end of the first shell portion.

268 words
A coaxial connector for termination to a coaxial cable that has an inner conductor surrounded by an inner insulator which is surrounded by a braiding which is surrounded by a jacket, wherein the connector includes a shell which can be changed between an initial configuration prior to termination to the coaxial cable and a final configuration during such termination, said shell having a tubular first portion with upper and lower sides that extends along a mate axis and a second portion which, in its final configuration extends along a termination axis that is substantially perpendicular to said mate axis, said first portion having forward and rearward ends with said rearward end being open in said initial configuration and closed in said final configuration and said second portion including first and second termination parts extending respectively from the lower and upper sides of said rearward end with said first termination part extending substantially parallel to said termination axis and said second termination part extending, in said initial configuration, at an angle of at least about 90° from said first termination part and being bendable to said final configuration to close the rear of said tubular first portion, wherein at least said first termination part forms part of a substantially tubular ferrule for receiving a cable inner insulation and for being surrounded by the cable braiding in said final configuration, characterized by: a tubular sleeve which can slide along the cable jacket and which has an inside of a diameter to closely surround the braiding, and which can be crimped to lock the cable braiding between itself and said ferrule.
