Abstract
Abstract A pin-carrying washer is seated on a shoulder facing toward the mouth end within and intermediate the length of the plug shell and is locked in place by a clamping shoulder crimped radially inwardly in the shell spaced from the seating shoulder. An annular radially outwardly projecting rib between the seating and clamping shoulders reinforces the shell and serves as a finger grip. A method of making the phono plug comprises initially constructing the shell outwardly from the seating shoulder of a diameter slightly larger than the diameter of the washer, inserting the washer through the mouth end of the shell onto the seating shoulder, retaining the shell about the seating shoulder and therebelow against deformation, and collapsing material of the shell wall radially inwardly to provide the clamping shoulder, as by applying axial force to the shell wall toward the seating shoulder.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
112 words
In a phono plug structure: a tubular one-piece electrically conductive shell body having a mouth at one end defined by jack-body-gripping fingers and having a terminal at its opposite end; an integral intermediate internal pin-disk-seating shoulder on said body facing toward said fingers; an annular radially outwardly projecting and radially inwardly opening hollow rib integral with said body and having one wall in part comprising a shoulder flange; and a spacing portion of the body intervening between the shoulder and a second wall of the rib which joins said intervening portion; whereby to enable clamping, locking engagement of the disk against said shoulder upon only slight inward displacement of said shoulder flange.
Claim 2
Dependent Claim
112 words
In a phono plug structure: a tubular one-piece electrically conductive shell body having a mouth at one end defined by jack-body-gripping fingers and having a terminal at its opposite end; an integral intermediate internal pin-disk-seating shoulder on said body facing toward said fingers; an annular radially outwardly projecting and radially inwardly opening hollow rib integral with said body and having one wall in part comprising a shoulder flange; and a spacing portion of the body intervening between the shoulder and a second wall of the rib which joins said intervening portion; whereby to enable clamping, locking engagement of the disk against said shoulder upon only slight inward displacement of said shoulder flange.
Claim 3
Dependent Claim
27 words
A structure according to claim 1, wherein said shoulder flange extends at least initially in slanting relation to said second wall and generally obliquely toward said fingers.
Claim 4
Dependent Claim
31 words
A structure according to claim 1, said flange and said one wall being wider than said second wall whereby the shoulder flange will overhang said shoulder for clamping the disk thereto.
Claim 5
Dependent Claim
56 words
A structure according to claim 1, having in combination therewith an insulating disk seated on said shoulder and carrying a plug pin, said shoulder flange engaging against the disk and thereby clamping and locking the disk onto said shoulder, and a generally radially inwardly directed strut flange integral with said body and reinforcing said shoulder flange.
Claim 6
Dependent Claim
118 words
In a phono plug structure: a tubular one-piece electrically conductive shell body having a mouth at one end defined by jack-body-gripping fingers and having a terminal at its opposite end; an integral intermediate internal pin-disk-seating shoulder on said body facing toward said fingers; an insulating disk seated on said shoulder and carrying a plug pin; an annular integral shoulder flange on said body facing toward said shoulder and engaging against the disk and clamping and locking the disk onto said shoulder; an annular radially outwardly projecting rib joining said shoulder flange to the body adjacent to said shoulder; and the portion of the body between said shoulder and said rib being shorter than the thickness of said disk.
Claim 7
Dependent Claim
118 words
In a phono plug structure: a tubular one-piece electrically conductive shell body having a mouth at one end defined by jack-body-gripping fingers and having a terminal at its opposite end; an integral intermediate internal pin-disk-seating shoulder on said body facing toward said fingers; an insulating disk seated on said shoulder and carrying a plug pin; an annular integral shoulder flange on said body facing toward said shoulder and engaging against the disk and clamping and locking the disk onto said shoulder; an annular radially outwardly projecting rib joining said shoulder flange to the body adjacent to said shoulder; and the portion of the body between said shoulder and said rib being shorter than the thickness of said disk.
Claim 8
Dependent Claim
17 words
A structure according to claim 5, in which said shoulder flange extends substantially parallel to the disk.
Claim 9
Dependent Claim
108 words
In a phono plug structure: a tubular one-piece electrically conductive shell body formed from thin material will a mouth at one end defined by jack-body-gripping fingers and having a terminal at its opposite end; an integral intermediate internal pin-disk-seating shoulder on said body facing towards said fingers; an insulating disk carrying a plug pin and seated on said shoulder; said body having an annular generally axially extending portion thereof about said disk and including a radially outwardly projecting hollow reinforcing rib axially spaced from said shoulder by said annular portion; and a radially inwardly crimped shoulder portion of said reinforcing rib clamping the disk against the seating shoulder.
Claim 10
Dependent Claim
108 words
In a phono plug structure: a tubular one-piece electrically conductive shell body formed from thin material will a mouth at one end defined by jack-body-gripping fingers and having a terminal at its opposite end; an integral intermediate internal pin-disk-seating shoulder on said body facing towards said fingers; an insulating disk carrying a plug pin and seated on said shoulder; said body having an annular generally axially extending portion thereof about said disk and including a radially outwardly projecting hollow reinforcing rib axially spaced from said shoulder by said annular portion; and a radially inwardly crimped shoulder portion of said reinforcing rib clamping the disk against the seating shoulder.
Claim 11
Dependent Claim
93 words
In a method of making a phono plug structure: assembling a pin-carrying insulating washer onto an iNternal shoulder intermediately in a tubular electrical conductive shell; displacing an integral annular flanger in said body from a clearance relation to said shoulder into clamping locking engagement with said disk and thrusting toward said shoulder; and shaping and sizing gripping fingers on said shell body from a normally generally cylindrical position into generally convergent relation as an incident to applying endwise compression to the shell for displacing said shoulder flange into the clamping and locking position.
Claim 12
Dependent Claim
93 words

Claim 13
Dependent Claim
