Claim 10

In a phonoconnector according to claim 7, said projection means being on the socket shell and deflected radially outwardly in engagement with said receptacle shell, and the wall of the socket shell being thereby reactively tensioned radially inwardly at said wall areas into said frictional engagement with the receptacle shell.

Claim 11

An assembly according to claim 7, wherein the projection means comprise a plurality of circumferentially spaced radially inward projections on said socket shell and said projections being tensionably deflected radially outwardly by the receptacle shell and acting to tensionably deflect the intermediate portions of the socket shell comprising said areas radially inwardly frictionally into engagement with the receptacle shell.

Claim 12

A phonoconnector according to claim 7, wherein said projection means comprise a plurality of circumferentially spaced longitudinally extending ribs.

Claim 13

A phonoconnector according to claim 10, including pinpoint interlock indentations in said socket shell in addition to said ribs and interlocking the socket shell and the receptacle shell.

Claim 14

A phonoconnector according to claim 7, wherein said projection means are formed on said receptacle shell and project radially outwardly into engagement with the socket shell.

Claim 15

A phonoconnector according to claim 12, wherein said projection means on the receptacle shell comprise a plurality of circumferentially spaced longitudinally extending and radially outwardly projecting ribs.

Claim 16

In a method of coupling a phonoconnector pin plug assembly with a phonoconnector receptacle having a shell, and wherein the pin plug is provided with a circumferentially solid but resiliently flexible wall socket shell of differentially larger diameter than the receptacle shell: mating the receptacle shell within the socket shell; in such mating pressing preformed radially extending projection means on the wall of one of said shells into frictional retaining engagement with the wall of the other of said shells and tensioning wall area of the socket shell radially outwardly at the projection means; and deflectably radially inwardly tensioning plain circumferentially arcuate wall areas of the socket shell at opposite sides of the projectIon means into frictional engagement with the receptacle shell.

Claim 17

In a method of coupling a phonoconnector pin plug assembly with a phonoconnector receptacle having a shell, and wherein the pin plug is provided with a circumferentially solid but resiliently flexible wall socket shell of differentially larger diameter than the receptacle shell: mating the receptacle shell within the socket shell; in such mating pressing preformed radially extending projection means on the wall of one of said shells into frictional retaining engagement with the wall of the other of said shells and tensioning wall area of the socket shell radially outwardly at the projection means; and deflectably radially inwardly tensioning plain circumferentially arcuate wall areas of the socket shell at opposite sides of the projectIon means into frictional engagement with the receptacle shell.

Claim 18

A method according to claim 14, comprising effecting said projection tensioning at three circumferentially spaced places, and effecting said area deflection tensioning at three areas intervening between said projection places.

Claim 19

A method according to claim 14, including crimpingly interlocking said shells.

Claim 20

A method according to claim 16, comprising effecting the crimping interlocking by pressing pinpoint crimping projections of a crimping tool into the mated shells.

Claim 21

In a phonoconnector pin plug assembly for coupling with a phono receptacle, said assembly having an electrically conductive pin plug and an electrically conductive socket shell in electrically insulated concentric relation thereabout, the improvement comprising: said shell having a circumferentially solid wall; said shell having inwardly projecting indentation means in said wall for retaining engagement with the perimeter of a phono receptacle shell coupled therein; said shell having a mouth end and an annular seat spaced inwardly from said mouth end and spaced from said indentation means; an insulating disk supporting said pin plug concentrically within said socket shell and having one side of an annular margin seated on said seat; and a plurality of circumferentially space indentations in said shell wall spaced from said seat substantially the same distance as the thickness of the disk and engaging the opposite side of the disk margin and thereby locking said disk in retained relation on said seat; said shell wall being resiliently flexible and having plain arcuate areas extending to a substantial width from opposite sides of the projection means and which areas are resiliently flexibly deflectable radially inwardly into engagement with a receptacle shell by radially outward tensioning of the indentation means when engaged with the receptacle shell.

Claim 22

In a phonoconnector pin plug assembly for coupling with a phono receptacle, said assembly having an electrically conductive pin plug and an electrically conductive socket shell in electrically insulated concentric relation thereabout, the improvement comprising: said shell having a circumferentially solid wall; said shell having inwardly projecting indentation means in said wall for retaining engagement with the perimeter of a phono receptacle shell coupled therein; said shell having a mouth end and an annular seat spaced inwardly from said mouth end and spaced from said indentation means; an insulating disk supporting said pin plug concentrically within said socket shell and having one side of an annular margin seated on said seat; and a plurality of circumferentially space indentations in said shell wall spaced from said seat substantially the same distance as the thickness of the disk and engaging the opposite side of the disk margin and thereby locking said disk in retained relation on said seat; said shell wall being resiliently flexible and having plain arcuate areas extending to a substantial width from opposite sides of the projection means and which areas are resiliently flexibly deflectable radially inwardly into engagement with a receptacle shell by radially outward tensioning of the indentation means when engaged with the receptacle shell.
