Aluminum tube coaxial cable connector

摘要

An aluminum tube coaxial cable connector for CATV applications is disclosed to include a tubular screw member having locating notches at the rear end, a T-shaped insulative stopper and an insulative insert mounted in the tubular screw member to hold a conducting core, an inner tube having lugs protruded from a front rim thereof and engaged into the locating notches of the tubular screw member to prohibit relative rotation between the tubular screw member and the inner tube, a packing component set mounted around the inner tube, and a casing threaded onto the tubular screw member to compress the packing component set and to further lock an inserted aluminum tube coaxial cable to the aluminum tube coaxial cable connector.

主权项

1. An aluminum tube coaxial cable connector, comprising:
a tubular screw member comprising an axial hole axially extending through opposing front and rear ends thereof, a tapered portion defined in the axial hole, a first outer thread disposed near the front end, a second outer thread disposed near the rear end, and at least one locating notch located on the rear end adjacent to said second outer thread; a T-shaped insulative stopper positioned in the axial hole in the front end of said tubular screw member; an insulative insert positioned in the axial hole in the rear end of said tubular screw member, said insulative insert comprising a center hole axially centering through opposing front and rear sides thereof; a conducting core inserted through said T-shaped insulative stopper and partially suspending outside the front end of said tubular screw member, said conducting core having a rear end thereof terminating in a clamping tube, said clamping tube defining therein a clamping hole; an inner tube comprising an axial hole extending through opposing front and rear ends thereof, a rim located at the front end and stopped against a part of said insulation insert, at least one lug protruded from said rim and engaged into said at least one locating notch of said tubular screw member, an accommodation open chamber defined in the front end in communication with the axial hole, a cup shell extending around the periphery thereof, and an annular mating space defined within said cup shell around the periphery of said inner tube; a packing component set comprising a packing ring inserted into said annular mating space in said cup shell of said inner tube, and a collar attached to said packing ring, said collar defining therein an inside space adapted for receiving said packing ring; and a casing surrounding said inner tube and said packing component set, said casing comprising an inside receiving space axially extending through opposing front and rear ends thereof for accommodating said inner tube, an inner thread spirally extending an inside wall thereof on a front side of said inside receiving space and threaded onto said second inner thread of said tubular screw member.
