Abstract

A male F-type coaxial cable connector including a nut, a body, a post, and a spacer, the spacer for bearing on the nut.

First claim

What is claimed is:

1. A male F-type coaxial cable connector comprising:
about a central axis, a coaxially arranged nut, body, and post;
the post including a shank and an end flange;
the nut rotatably coupled with the body via the post;
a forward spacer interposed between the post flange and a nut flange;
the forward spacer bearing on the post flange and on the nut flange;
a rearward spacer interposed between a body front face and the nut flange;
the rearward spacer bearing on the body front face and on the nut flange;
wherein the forward spacer is an electrical insulator and the rearward spacer is an electrical conductor; and,
wherein the rearward spacer contacts the post and the nut and electrically interconnects the post with the nut.

2. The connector of claim 1 wherein during movement of the nut flange with respect to the post flange, the spacers remain in physical contact with the nut flange.

3. The connector of claim 2 wherein one of the spacers provides a seal between the nut and the post.

4. A male F-type coaxial cable connector comprising:
about a central axis, a coaxially arranged nut, body, and post;
the post including a shank and an end flange;
the nut rotatably coupled with the body via the post;
a forward spacer interposed between the post flange and a nut flange;
the forward spacer bearing on the post flange and on the nut flange;
a rearward spacer interposed between a body front face and the nut flange;
the rearward spacer bearing on the body front face and on the nut flange;
wherein each of the spacers encircles the post shank but not the post flange; and,
wherein each of the spacers circumferentially contacts the post shank.

5. A male F-type coaxial cable connector comprising:
about a central axis, a coaxially arranged nut, body, and post;
the post including a shank and an end flange;
the nut rotatably coupled with the body via the post;
a forward spacer interposed between the post flange and a nut flange;
the forward spacer bearing on the post flange and on the nut flange;
a rearward spacer interposed between a body front face and the nut flange;
the rearward spacer bearing on the body front face and on the nut flange;
wherein the spacers are resilient and exert opposed collinear forces on the nut flange, movement of the nut flange with respect to the post flange accompanied by contraction of one of the spacers and expansion of the other of the spacers; and,
wherein one of the spacers includes a portion that extends into a radial gap between the post shank and the nut flange.

6. A male F-type coaxial cable connector comprising:
a nut, body, and post coaxially arranged about a central axis;
the post having a shank with a flanged end, the post interconnecting the nut and the body;
an annular nut flange with a forward face opposite a trailing face;
a forward spacer interposed between the post flange and the nut flange;
the forward spacer bearing on the post flange and on the nut forward face;
a rearward spacer interposed between a body front face and the nut flange; and,
the rearward spacer bearing on the body front face and on the nut trailing face;
wherein each of the spacers encircles the post shank and circumferentially contacts the post shank.

7. A male F-type coaxial cable connector comprising:
a nut, body, and post coaxially arranged about a central axis;
the post having a shank with a flanged end, the post interconnecting the nut and the body;
an annular nut flange with a forward face opposite a trailing face;
a forward spacer interposed between the post flange and the nut flange;
the forward spacer bearing on the post flange and on the nut forward face;
a rearward spacer interposed between a body front face and the nut flange;
the rearward spacer bearing on the body front face and on the nut trailing face;
wherein the forward spacer is an electrical insulator and the rearward spacer is an electrical conductor; and,
wherein the rearward spacer contacts the post and the nut and electrically interconnects the post and the nut.

8. The connector of claim 7 wherein during movement of the nut flange with respect to the post flange, the spacers remain in physical contact with the nut flange.

9. The connector of claim 8 wherein one of the spacers provides a seal between the nut and the post.
