Abstract
Abstract An apparatus for terminating a coaxial cable includes a connection pin and a spring sleeve having first and second spring portions, the first spring portion receiving one end of the connection pin and the second spring portion receiving an end of a center conductor of the coaxial cable. The second spring portion has a conical outer surface received within a conical hole of a sleeve held in place by first and second connector bodies, the sleeve increasing a clamping force of the second spring portion on the center conductor when the center conductor is subjected to pull-out load.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
153 words
An apparatus for terminating a conductor, comprising: a spring sleeve having first and second spring portions sized to receive a connection pin and the conductor respectively therein, the first and second spring portions being constructed such that a pull-out clamping force exerted on the connection pin by the first spring portion is less than a pull-out clamping force exerted on the conductor by the second spring portion, said second spring portion having a conical outer surface on one end thereof; and means for engaging said conical outer surface such that movement of said spring sleeve relative to said engaging means along a predetermined direction increases said clamping force on said conductor, the connection pin being fixed and contained within the first spring portion of the spring sleeve, the spring sleeve being preferentially moveable relative to the connection pin rather than the conductor when the conductor is urged axially away from the connection pin.
Claim 2
Independent Claim
153 words
An apparatus for terminating a conductor, comprising: a spring sleeve having first and second spring portions sized to receive a connection pin and the conductor respectively therein, the first and second spring portions being constructed such that a pull-out clamping force exerted on the connection pin by the first spring portion is less than a pull-out clamping force exerted on the conductor by the second spring portion, said second spring portion having a conical outer surface on one end thereof; and means for engaging said conical outer surface such that movement of said spring sleeve relative to said engaging means along a predetermined direction increases said clamping force on said conductor, the connection pin being fixed and contained within the first spring portion of the spring sleeve, the spring sleeve being preferentially moveable relative to the connection pin rather than the conductor when the conductor is urged axially away from the connection pin.
Claim 3
Dependent Claim
25 words
The apparatus as claimed in claim 1, at least one of said first and second spring portions comprising a plurality of longitudinally extending spring legs.
Claim 4
Dependent Claim
30 words
The apparatus as claimed in claim 2, said spring legs of said second spring portion engaging said conductor having having a plurality of teeth formed thereon for engaging said conductor.
Claim 5
Dependent Claim
58 words
The apparatus as claimed in claim 1, further comprising first and second connector bodies for holding and limiting axial movement of said engaging means and said spring sleeve, the second spring portion being sized and constructed such that the conductor is insertable into the second spring portion subsequent to the first and second connector bodies being completely assembled.
Claim 6
Dependent Claim
47 words
The apparatus as claimed in claim 4, further comprising a metal shield disposed on a side of said engaging means opposite said second spring portion, said conductor comprising a center conductor of a coaxial cable, said metal shield being adapted for receiving therearound a coaxial cable shield.
Claim 7
Dependent Claim
31 words
The apparatus as claimed in claim 1, said conductor comprising a center conductor of a coaxial cable, the connection pin being fixedly connected to a junction box or a drop box.
Claim 8
Independent Claim
182 words
A method of making a termination for a center conductor of a coaxial cable, comprising the steps of: disposing a first spring portion of a spring sleeve having the first and a second spring portion around a connection pin, said second spring portion being shaped so as to exert a clamping force on a center conductor inserted therein which is larger than the clamping force exerted by the first spring portion on the connection pin; disposing a second sleeve around an outer conical surface of the second spring portion so as to increase said clamping force of said second spring portion when said second spring portion is moved in a direction opposite from said connection pin; enclosing the spring sleeve and the second sleeve in their final assembled configuration in a housing such that the center conductor can thereafter be inserted into the second spring portion and be clamped thereby against removal therefrom without adjusting the housing; and inserting said center conductor into said second spring portion subsequent to enclosing the spring sleeve and the second sleeve in their final assembled configuration.
Claim 9
Independent Claim
182 words
A method of making a termination for a center conductor of a coaxial cable, comprising the steps of: disposing a first spring portion of a spring sleeve having the first and a second spring portion around a connection pin, said second spring portion being shaped so as to exert a clamping force on a center conductor inserted therein which is larger than the clamping force exerted by the first spring portion on the connection pin; disposing a second sleeve around an outer conical surface of the second spring portion so as to increase said clamping force of said second spring portion when said second spring portion is moved in a direction opposite from said connection pin; enclosing the spring sleeve and the second sleeve in their final assembled configuration in a housing such that the center conductor can thereafter be inserted into the second spring portion and be clamped thereby against removal therefrom without adjusting the housing; and inserting said center conductor into said second spring portion subsequent to enclosing the spring sleeve and the second sleeve in their final assembled configuration.
Claim 10
Dependent Claim
17 words
The method of claim 7, the connection pin being fixed to a junction box or drop box.
