Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
121 words
In an electrical connector having cooperable mating and unmating plug and receptacle means, each provided with an insert member of dielectric material carrying electrical contact elements and axially positioned within a shell with reference to a selected mating relationship, the combination of: means for retaining at least one of said insert members against axial displacement in one direction including a compressible insert ring member having external thread means of one configuration; said one of said shells having internal thread means of a second different configuration; said ring member being linearly pressure driven in a direction opposite to said one direction whereby said external and internal thread means are pressure interlocked at angularly spaced intersections of said external and internal thread means.
Claim 2
Dependent Claim
121 words
In an electrical connector having cooperable mating and unmating plug and receptacle means, each provided with an insert member of dielectric material carrying electrical contact elements and axially positioned within a shell with reference to a selected mating relationship, the combination of: means for retaining at least one of said insert members against axial displacement in one direction including a compressible insert ring member having external thread means of one configuration; said one of said shells having internal thread means of a second different configuration; said ring member being linearly pressure driven in a direction opposite to said one direction whereby said external and internal thread means are pressure interlocked at angularly spaced intersections of said external and internal thread means.
Claim 3
Dependent Claim
17 words
In a connector as stated in claim 1 wherein said insert ring member is of thermoplastic material.
Claim 4
Dependent Claim
70 words
In an electrical connector as stated in claim 1 wherein said external thread configuration of said insert ring member includes a thread face normal to the axis of the connector and facing said one direction, and the thread configuration of said shell including a thread face normal to the said axis and facing toward said opposite direction, said interlocked pressure engagement occurring at spaced areas of said normal thread faces.
Claim 5
Dependent Claim
34 words
In an electrical connector as stated in claim 1 wherein the twist of the thread means on said insert ring member is opposite to the twist of the thread means on said one shell.
Claim 6
Dependent Claim
38 words
In an electrical connector as stated in claim 1 wherein the ratio of the number of threads per inch on said insert ring member is approximately twice the number of the threads per inch on said one shell.
Claim 7
Dependent Claim
35 words
In an electrical connector as stated in claim 1 wherein the thread configuration of both external and internal thread means includes sloping faces to facilitate movement of the insert ring member along said opposite direction.
Claim 8
Dependent Claim
32 words
In an electrical connector as stated in claim 1 wherein the ratio of the number of thread leads on said insert ring member and said one shell is approximately 1 to 2.
Claim 9
Dependent Claim
81 words
An insert ring member for restricting axial movement in one direction of one of two telescopically related members comprising: a plastic ring member of compressible thermoplastic material having external threads selectively configured to have a sloping face in one direction, a face normal to the axis of the ring member in the other direction, and a flat root face between said sloping and normal faces of adjacent threads, said sloping face and said normal face intercepting and forming an acute angle.
Claim 10
Dependent Claim
81 words
An insert ring member for restricting axial movement in one direction of one of two telescopically related members comprising: a plastic ring member of compressible thermoplastic material having external threads selectively configured to have a sloping face in one direction, a face normal to the axis of the ring member in the other direction, and a flat root face between said sloping and normal faces of adjacent threads, said sloping face and said normal face intercepting and forming an acute angle.
Claim 11
Dependent Claim
18 words
An insert ring member as claimed in claim 8 wherein one end of said ring member is tapered.
Claim 12
Dependent Claim
84 words
Means for restricting axial displacement in one direction of a first member positioned within a second hollow member comprising: internal thread means on said second hollow member; a compressible retainer ring having external thread means; said internal thread means and said external thread means being turned in opposite directions; said retainer ring being axially driven between said first and second members to pressure interlock said oppositely directed thread means at angularly spaced intervals; said first member having a shoulder cooperable with said retainer ring.
Claim 13
Dependent Claim
84 words
Means for restricting axial displacement in one direction of a first member positioned within a second hollow member comprising: internal thread means on said second hollow member; a compressible retainer ring having external thread means; said internal thread means and said external thread means being turned in opposite directions; said retainer ring being axially driven between said first and second members to pressure interlock said oppositely directed thread means at angularly spaced intervals; said first member having a shoulder cooperable with said retainer ring.
Claim 14
Dependent Claim
30 words
In a means as claimed in claim 10 wherein said thread means in pressure interlocked relation include thread faces in abutment in planes normal to the axes of said members.
Claim 15
Dependent Claim
20 words
In a means as claimed in claim 10 wherein one of the thread means includes more than one thread lead.
Claim 16
Dependent Claim
81 words
Means for restricting axial displacement in one direction of a first member positioned within a second hollow member comprising: internal thread means on said second hollow member; a compressible retainer ring having external thread means; one of said thread means including more than one thread lead; said retainer ring being positioned between said first and second members to pressure interlock said thread means at angularly spaced intervals; said first member having means limiting movement of said retainer ring in one direction.
Claim 17
Dependent Claim
81 words
Means for restricting axial displacement in one direction of a first member positioned within a second hollow member comprising: internal thread means on said second hollow member; a compressible retainer ring having external thread means; one of said thread means including more than one thread lead; said retainer ring being positioned between said first and second members to pressure interlock said thread means at angularly spaced intervals; said first member having means limiting movement of said retainer ring in one direction.
Claim 18
Dependent Claim
26 words
In a means as claimed in claim 13 wherein the ratio of the number of thread leads of said thread means is approximately one to two.
Claim 19
Dependent Claim
37 words
In a means as claimed in claim 13 wherein the ratio of the number of threads per inch on said external thread means is approximately twice the number of threads per inch on said internal thread means.
