Abstract
Abstract A clamp-type coaxial connector having a one-piece clamp assembly. The clamp assembly includes a clamp nut, a clamp bushing, and a clamp ferrule. The nut and bushing each include a member adapted to coact with the member of the other element to secure the nut and bushing together in a manner such as to permit limited axial movement between the elements. The nut is adapted to coact with a connector body to secure the clamp assembly to the body and to drive the nut and bushing toward each other. A counter-bore exists in the nut and/or the bushing in which the ferrule is captivated, the counter-bore having an angled surface which coacts with the ferrule as the nut and bushing are driven toward each other to clamp the ferrule against the outer conductor of a coaxial cable.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
230 words
A connector for a coaxial cable having a inner and an outer conductor comprising: a conductive body member having an axial bore and a rearwardly extending sleeve; a block of insulating material in said bore, said block having an axial bore; a contact member adapted to be positioned In said bore and to be physically and electrically connected to said inner conductor; and a clamp assembly fitted into said body sleeve, said assembly including a clamp nut element, a clamp bushing element and a clamp ferrule, said nut element and bushing element each including a member coacting with the member of the other element to secure said nut element and bushing element together while permitting limited axial movement between the elements, said ferrule being captivated between said elements, said nut element including means coacting with said sleeve to secure said assembly in said sleeve and drive said elements toward each other, said nut element, ferrule and bushing element each having an axial bore which bores are aligned and which bores are adapted to receive said outer conductor, a counter-bore in at least one of said elements, said counter-bore having a surface at an angle to the axis of the assembly and being located in the end of said element adjacent the captivated ferrule, said surface being adapted to coact with said ferrule to clamp said ferrule against said outer conductor.
Claim 2
Dependent Claim
230 words
A connector for a coaxial cable having a inner and an outer conductor comprising: a conductive body member having an axial bore and a rearwardly extending sleeve; a block of insulating material in said bore, said block having an axial bore; a contact member adapted to be positioned In said bore and to be physically and electrically connected to said inner conductor; and a clamp assembly fitted into said body sleeve, said assembly including a clamp nut element, a clamp bushing element and a clamp ferrule, said nut element and bushing element each including a member coacting with the member of the other element to secure said nut element and bushing element together while permitting limited axial movement between the elements, said ferrule being captivated between said elements, said nut element including means coacting with said sleeve to secure said assembly in said sleeve and drive said elements toward each other, said nut element, ferrule and bushing element each having an axial bore which bores are aligned and which bores are adapted to receive said outer conductor, a counter-bore in at least one of said elements, said counter-bore having a surface at an angle to the axis of the assembly and being located in the end of said element adjacent the captivated ferrule, said surface being adapted to coact with said ferrule to clamp said ferrule against said outer conductor.
Claim 3
Dependent Claim
38 words
A connector of the type described in claim 1 wherein the members on said nut element and bushing element are projections having a lip at their end, the projection of at least one of said elements being resilient.
Claim 4
Dependent Claim
26 words
A connector of the type described in claim 2 wherein the projection of said nut element is in the form of a plurality of resilient fingers.
Claim 5
Dependent Claim
43 words
A connector of the type described in claim 2 wherein the engaging surfaces of said lips are perpendicular to the connector axis and wherein the leading edge of at least one of said lips is angled to permit easy assembly of the elements.
Claim 6
Dependent Claim
70 words
A connector of the type described in claim 4 wherein each of said elements has a shoulder substantially parallel to the engaging surface of the element lip and spaced a predetermined distance from said engaging surface, and wherein the lip of an element may move between a position against the engaging surface of the mating lip of the other element and a position against the shoulder of the other element.
Claim 7
Dependent Claim
28 words
A connector of the type described in claim 1 wherein said sleeve in internally threaded; and wherein the coacting means on said nut element is an external thread.
Claim 8
Dependent Claim
83 words
A connector of the type described in claim 1 wherein said body has a wall at the rear of said sleeve; wherein said bushing element butts against said wall in a predetermined partially assembled condition of said body and assembly; and wherein continued operation of the coacting means to assemble said body and assembly past said predetermined condition drives said nut element toward said bushing element with the captivated ferrule being compressed by the angled counter-bore surface to effect the desired clamping action.
Claim 9
Dependent Claim
180 words
A one-piece clamp assembly for a coaxial connector, said connector having a conductive body member and being adapted to be secured to a coaxial cable having an inner and an outer conductor, comprising: a clamp nut element having means for coacting with said body to secure said assembly to said body; a clamp bushing element; said nut element and bushing element each including a member coacting with the member of the other element to secure the elements together while permitting limited axial movement between the elements; a clamp ferrule captivated between said nut element and bushing element; an axial bore adapted to accept said outer conductor, said bore being formed through the assembled nut element, bushing element and ferrule; and a counter-bore having a surface at an angle to the axis of said bore formed in at least one of said elements in the end thereof adjacent said ferrule, said angled surface being adapted to coact with said ferrule as said nut element and bushing element are moved axially toward each other to clamp said ferrule against said outer conductor.
Claim 10
Dependent Claim
180 words
A one-piece clamp assembly for a coaxial connector, said connector having a conductive body member and being adapted to be secured to a coaxial cable having an inner and an outer conductor, comprising: a clamp nut element having means for coacting with said body to secure said assembly to said body; a clamp bushing element; said nut element and bushing element each including a member coacting with the member of the other element to secure the elements together while permitting limited axial movement between the elements; a clamp ferrule captivated between said nut element and bushing element; an axial bore adapted to accept said outer conductor, said bore being formed through the assembled nut element, bushing element and ferrule; and a counter-bore having a surface at an angle to the axis of said bore formed in at least one of said elements in the end thereof adjacent said ferrule, said angled surface being adapted to coact with said ferrule as said nut element and bushing element are moved axially toward each other to clamp said ferrule against said outer conductor.
Claim 11
Dependent Claim
