Abstract

A coaxial connector includes an outer conductor portion including a polymer shell, the polymer shell defining an inner bore extending from a first open end to a second open end opposite the first open end, and a conductive layer positioned on the inner bore of the polymer shell, an outer surface of the polymer shell, or both, where the conductive layer is structurally configured to be electrically coupled to an outer conductor of a coaxial transmission medium, an electrically-insulating intermediate member positioned at least partially within the inner bore of the polymer shell, and an inner conductor portion engaged with the electrically-insulating intermediate member and positioned at least partially within the inner bore of the polymer shell, where the inner conductor portion is configured to be electrically coupled to an inner conductor of the coaxial transmission medium and electrically isolated from the conductive layer of the outer conductor portion.

First claim

The invention claimed is:

1 . A coaxial connector, comprising:
an outer conductor portion, comprising:
a polymer shell extending in an axial direction, the polymer shell defining an inner bore extending from a first open end to a second open end opposite the first open end, wherein the first open end comprises at least two deformable portions that are elastically deformable in a radial direction transverse to the axial direction;
a conductive layer positioned on the inner bore of the polymer shell and an outer surface of the polymer shell, wherein the conductive layer continuously wraps around an end of the at least two deformable portions of the polymer shell from the inner bore to the outer surface, the conductive layer being structurally configured to be electrically coupled to an outer conductor of a coaxial transmission medium;
an electrically-insulating intermediate member positioned at least partially within the inner bore of the polymer shell; and
an inner conductor portion engaged with the electrically-insulating intermediate member and positioned at least partially within the inner bore of the polymer shell, wherein the inner conductor portion is configured to be electrically coupled to an inner conductor of the coaxial transmission medium and electrically isolated from the conductive layer of the outer conductor portion.

2 . The coaxial connector of claim 1 , wherein the at least two deformable portions are separated by at least two slots extending from the first open end along the axial direction.

3 . The coaxial connector of claim 1 , wherein the outer surface defines an inwardly extending taper.

4 . The coaxial connector of claim 1 , wherein the inner conductor portion defines a first inner conductor bore at the first open end and a second inner conductor bore at the second open end.

5 . The coaxial connector of claim 1 , wherein the polymer shell defines an outwardly-extending flange at the first open end.

6 . The coaxial connector of claim 5 , wherein the outwardly-extending flange defines a rounded surface.

7 . The coaxial connector of claim 5 , wherein the outwardly-extending flange defines an inwardly-facing surface that faces in the axial direction.

8 . The coaxial connector of claim 5 , wherein the outwardly-extending flange defines an inwardly-facing surface orthogonal to an adjacent surface of the polymer shell.

9 . The coaxial connector of claim 1 , wherein the outer surface defines one or more inwardly-extending grooves.

10 . The coaxial connector of claim 1 , wherein the polymer shell defines a thread at the second open end.

11 . A coaxial connector, comprising:
an outer conductor portion, comprising:
an outer shell extending in an axial direction, the outer shell defining an inner bore extending from a first open end to a second open end opposite the first open end, wherein the first open end comprises at least two deformable portions that are elastically deformable in a radial direction transverse to the axial direction;
a conductive layer positioned on the inner bore of the polymer shell and an outer surface of the polymer shell, wherein the conductive layer continuously wraps around an end of the at least two deformable portions of the polymer shell from the inner bore to the outer surface, the conductive layer being structurally configured to be electrically coupled to an outer conductor of a coaxial transmission medium;
an electrically-insulating intermediate member positioned at least partially within the inner bore of the outer shell; and
an inner conductor portion engaged with the electrically-insulating intermediate member positioned at least partially within the inner bore of the outer shell, wherein the inner conductor portion is configured to be electrically coupled to an inner conductor of the coaxial transmission medium and electrically isolated from the conductive layer of the outer conductor portion.

12 . The coaxial connector of claim 11 , wherein the outer surface defines an inwardly extending taper.

13 . The coaxial connector of claim 11 , wherein the outer shell defines an outwardly-extending flange at the first open end.

14 . The coaxial connector of claim 13 , wherein the outwardly-extending flange defines a rounded surface.

15 . The coaxial connector of claim 13 , wherein the outwardly-extending flange defines an inwardly-facing surface oriented in the axial direction.

16 . The coaxial connector of claim 11 , wherein the outer surface defines one or more inwardly-extending grooves.

17 . A method for forming coaxial connector, the method comprising:
molding a polymer to form an outer conductor portion having an outer shell that defines an outer surface and an inner bore extending from a first open end to a second open end opposite the first open end, wherein the first open end comprises at least two deformable portions that are elastically deformable in a radial direction transverse to the axial direction; applying a conductive layer to the inner bore and the outer surface, wherein the conductive layer continuously wraps around an end of the at least two deformable portions of the polymer shell from the inner bore to the outer surface; and inserting an inner conductor portion at least partially into the inner bore of the outer shell, wherein the inner conductor portion is structurally configured to be electrically coupled to an inner conductor of a coaxial transmission medium.

18 . The method of claim 17 , wherein applying the conductive layer comprises at least one of chemical deposition and physical deposition.

19 . The coaxial connector of claim 1 , wherein:
the outer conductive portion comprises a first portion including the first open end and a second portion including the second open end; and the outer surface defines a plurality of inwardly-extending grooves circumscribing the outer conductive portion.
