Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
248 words
A cable plug connector for insulated coaxial cable: the cable comprises an internal conductor, a dielectric layer outside said internal conductor, a thin metal layer external conductor positioned around and supported on said dielectric layer and an external protective casing of insulating material around said external conductor; an annular section of said casing is removed to facilitate electric contact with said external conductor; said connector comprises a first sleeve positioned around said external protective casing of said cable; said first sleeve having a first end; a resilient spring contact ring around said exposed annular section of said external conductor; said ring having one edge portion which is supported said first sleeve at its said first end; said ring having a free edge portion opposite its said one edge portion; said ring is so shaped and oriented in said first sleeve that its said free edge portion is normally raised above said annular section of said external conductor and is radially deflectable inwardly against said annular section of said external conductor; a second sleeve with a first end that faces toward said first sleeve first end and having a bore near said second sleeve first end; said second sleeve bore is shaped to cause said ring free edge portion to deflect radially inwardly and to cause said ring to engage said extErnal conductor annular section, and is shaped to cause such deflection of said ring as said second sleeve first end is moved toward said first sleeve first end.
Claim 2
Dependent Claim
248 words
A cable plug connector for insulated coaxial cable: the cable comprises an internal conductor, a dielectric layer outside said internal conductor, a thin metal layer external conductor positioned around and supported on said dielectric layer and an external protective casing of insulating material around said external conductor; an annular section of said casing is removed to facilitate electric contact with said external conductor; said connector comprises a first sleeve positioned around said external protective casing of said cable; said first sleeve having a first end; a resilient spring contact ring around said exposed annular section of said external conductor; said ring having one edge portion which is supported said first sleeve at its said first end; said ring having a free edge portion opposite its said one edge portion; said ring is so shaped and oriented in said first sleeve that its said free edge portion is normally raised above said annular section of said external conductor and is radially deflectable inwardly against said annular section of said external conductor; a second sleeve with a first end that faces toward said first sleeve first end and having a bore near said second sleeve first end; said second sleeve bore is shaped to cause said ring free edge portion to deflect radially inwardly and to cause said ring to engage said extErnal conductor annular section, and is shaped to cause such deflection of said ring as said second sleeve first end is moved toward said first sleeve first end.
Claim 3
Dependent Claim
19 words
The connector of claim 1, wherein said second sleeve bore tapers conically radially inwardly away from said first sleeve.
Claim 4
Dependent Claim
23 words
The connector of claim 2, wherein said first sleeve has a self cutting internal thread therein, which is screwed onto said protective casing.
Claim 5
Dependent Claim
24 words
The connector of claim 1, wherein said front end of said first sleeve is slotted and in the slot is soldered said contact ring.
Claim 6
Dependent Claim
33 words
The structure as set forth in claim 1, in which said spring contact ring is constructed in the manner of a comb and is divided by cut away portions into individual resilient lugs.
Claim 7
Dependent Claim
44 words
The connector of claim 5, wherein each said lug is curved radially outwardly to form an arch and is so shaped and oriented that said lugs are forced inwardly by said second sleeve bore to cause their center portions to engage said external conductor.
Claim 8
Dependent Claim
61 words
The connector of claim 6, wherein said external conductor has a front edge which is included in said annular section and is located so as to extend out of said first sleeve; said lugs extend past said external conductor front edge and make contact therewith; said second sleeve bore receives said ring free edge portion and biases said lugs radially inwardly.
Claim 9
Dependent Claim
40 words
The connector of claim 6, wherein an annular section of said external conductor is removed to expose said dielectric layer; said second sleeve having an internal thread therein which is screwed onto said exposed annular section of said dielectric support.
