Joint between coaxial cable and microwave component

Claim 2

A connectorless joint between a coaxial cable and a microwave component comprising a microwave component having a tubular metal housing, a coaxial cable havng a metal outer jacket, one end of said component having an integral female receptacle in a first axial bore, a dielectric surrounding said receptacle and being located between the surface of said bore and said receptacle, said one end of said component terminating at a second axial bore which communicates with one end of said first bore, the diameter of the second bore being greater than the diameter of the first bore so as to define a radial shoulder, the coaxial cable having its center conductor projecting beyond an end face, said cable extending into said second bore with said cable end face contacting said shoulder, said cable center conductor contacting said receptacle, and said one end of said component being metallurgically bonded to the outer jacket of said coaxial cable.

Claim 3

A joint in accordance with claim 1 wherein said component is in an attenuator.

Claim 4

A joint in accordance with claim 1 wherein said one end of said tubular metal housing is tapered from its outer periphery to an axial projection of reduced diameter.

Claim 5

A joint in accordance with claim 1 wherein said jacket and housing are metallurgically bonded by use of solder.

Claim 6

A joint in accordance with claim 1 including a second coaxial cable connected to the other end of said component in the same manner.

Claim 7

A connectorless joint between a coaxial cable and a microwave component comprising an attenuator having a tubular metal conductive housing, a coaxial cable having a metal outer jacket, one end of said attenuator having an integral female receptacle in a first axial bore, a dielectric surrounding said receptacle and being located between the surface of said bore and said receptacle, said one end of said attenuator terminating at a second axial bore which communicates with one end of said first bore, the diameter of the second bore being greater than the diameter of the first bore so as to define a radial shoulder, the coaxial cable having its center conductor projecting beyond an end face, said cable extending into said second bore with said cable end face contacting said shoulder, said cable center conductor contacting said receptacle, said one end of said tubular metal housing being tapered from its outer periphery to an axial projection of reduced diameter, said projection containing at least a portion of said second bore, and said projection being soldered to the outer jacket of said coaxial cable.

Claim 8

A connectorless joint between a coaxial cable and a microwave component comprising an attenuator having a tubular metal conductive housing, a coaxial cable having a metal outer jacket, one end of said attenuator having an integral female receptacle in a first axial bore, a dielectric surrounding said receptacle and being located between the surface of said bore and said receptacle, said one end of said attenuator terminating at a second axial bore which communicates with one end of said first bore, the diameter of the second bore being greater than the diameter of the first bore so as to define a radial shoulder, the coaxial cable having its center conductor projecting beyond an end face, said cable extending into said second bore with said cable end face contacting said shoulder, said cable center conductor contacting said receptacle, said one end of said tubular metal housing being tapered from its outer periphery to an axial projection of reduced diameter, said projection containing at least a portion of said second bore, and said projection being soldered to the outer jacket of said coaxial cable.

Claim 9

A joint in accordance with claim 6 including a second coaxial cable connected to the other end of said attenuator in the same manner.

Claim 10

A joint in accordance with claim 6 wherein said attenuator has a length of about 0.7 inches and a weight of about 0.069 oz.
