Abstract

A coaxial cable connector is disclosed. The connector includes a body, a backnut, a clamping insert and a deformable helical split washer. The deformable split washer, clamping insert, body and backnut provide a simple means for deforming and clamping the outer conductor. In one disclosed embodiment, the split washer is captivated in a tubular extension to facilitate installation on the outer conductor.

Claims

1. A connector for connecting a coaxial cable having an inner-conductor and a helically corrugated outer-conductor comprising:

a cylindrical body having an interior, an internal threaded portion for engagement with a threaded backnut, and a shoulder portion for supporting a VSWR compensating clamping insert, the shoulder portion being disposed within its interior;

an inner conductor contact having a dielectric spacer disposed thereover, the inner conductor contact being disposed within the interior of the cylindrical body and the dielectric spacer being dimensioned so as to provide a snug fit within the interior of the cylindrical body;

a VSWR compensating cup shaped clamping insert, the clamping insert further having a body abutting end, a base with an opening which is dimensioned to allow the inner conductor to pass therethrough and an interior shoulder at the body abutting end for supporting a dielectric insert, and wherein the clamping insert member is disposed within the cylindrical body so that the body abutting end is adjacent to the shoulder portion of the body;

a dielectric insert having an opening with a diameter which is sufficient to allow an inner conductor to pass therethrough, wherein the dielectric insert is disposed within the clamping insert adjacent to its shoulder portion;

a backnut having a terminal end which resides within the body, an interior threaded portion with threads corresponding to the helical corrugations of the outer conductor, an exterior threaded portion for cooperating with the internal threaded portion of the body, a bearing surface at its internal terminal end; and

a deformable helical split washer having a pair of facing ends;

whereby, the outer conductor is deformed and clamped between the split washer and the base of the clamping insert, and whereby the split washer is deformed when the connector is assembled by threading the interior threads of the body with the exterior threads of the backnut.

2. The connector of claim 1, wherein the backnut further comprises a tubular extension extending coaxially from its bearing surface having dimensions suitable for captivating the split washer therein.

3. The connector of claim 2, wherein the tubular extension further includes an inwardly facing rim for further captivating the split washer.

4. The connector of claim 3, wherein the tubular extension further includes a pair of longitudinal ridges within its interior for engaging the facing ends of the split washer.

5. The connector of claim 2, wherein the outside diameter of the clamping insert is dimensioned so as to permit the tubular extension to reside between the clamping insert and the body when the connector is assembled.

6. The connector of claim 5, wherein the body abutting end of the clamping insert is provided with a outwardly extending flange.

7. A connector for connecting a coaxial cable having an inner-conductor and a helically corrugated outer-conductor comprising:

a cylindrical body having an interior, an internal threaded portion for engagement with a threaded backnut, and a shoulder portion for supporting a VSWR compensating clamping insert, the shoulder portion being disposed within its interior;

an inner conductor contact having a dielectric spacer disposed thereover, the inner conductor contact being disposed within the interior of the cylindrical body and the dielectric spacer being dimensioned so as to provide a snug fit within the interior of the cylindrical body;

a VSWR compensating cup shaped clamping insert, the clamping insert further having a body abutting end, a base with an opening which is dimensioned to allow the inner conductor to pass therethrough and an interior shoulder at the body abutting end for supporting a dielectric insert, and wherein the clamping insert member is disposed within the cylindrical body so that the body abutting end is adjacent to the shoulder portion of the body;

a dielectric insert having an opening with a diameter which is sufficient to allow an inner conductor to pass therethrough, wherein the dielectric insert is disposed within the clamping insert adjacent to its shoulder portion;

a backnut having a terminal end which resides within the body, an exterior threaded portion for cooperating with the internal threaded portion of the body, a bearing surface at its internal terminal end, and a tubular extension extending coaxially from its bearing surface;

a deformable helical split washer having a pair of facing ends, the split washer being disposed within the tubular extension of the backnut;

whereby, the outer conductor is deformed and clamped between the split washer and the base of the clamping insert, and whereby the split washer is deformed when the connector is assembled by threading the interior threads of the body with the exterior threads of the backnut.

8. The connector of claim 7, wherein the tubular extension further includes an inwardly facing rim for further captivating the split washer.

9. The connector of claim 8, wherein the tubular extension further includes a pair of longitudinal ridges within its interior for engaging the facing ends of the split washer.

10. The connector of claim 7, wherein the outside diameter of the clamping insert is dimensioned so as to permit the tubular extension to reside between the clamping insert and the body when the connector is assembled.

11. The connector of claim 10, wherein the body abutting end of the clamping insert is provided with a outwardly extending flange.
