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:
a nut, body, and post arranged about a central axis;
the nut between a nut back wall and a nut mouth for receiving a port, the back wall extending radially inward and defining an aperture proximate the 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 the nut back wall;
the forward spacer bearing on the post flange and on a forward face of the back wall;
a rearward spacer interposed between a body front face and the nut back wall; and;
the rearward spacer bearing on the body front face and on a rearward face of the back wall;
wherein the forward spacer electrically insulates the post flange from the back wall.

2. The connector of claim 1 wherein the spacers are resilient and exert opposed colinear forces on the back wall, movement of the back wall with respect to the post flange accompanied by contraction of one of the spacers and expansion of the other of the spacers.

3. The connector of claim 1 wherein the nut is electrically isolated from the post.

4. The connector of claim 1 wherein the forward spacer is an electrical insulator and the rearward spacer is an electrical conductor.

5. The connector of claim 1 wherein prior to being mated with a mating connector, an axial gap exists between the nut and the body.

6. The connector of claim 1 wherein the back wall forward face and the back wall rearward face lie in parallel planes.

7. The connector of claim 6 wherein a back wall rearward face lies in a plane perpendicular to the central axis, the plane being axially spaced apart from the body.

8. The connector of claim 1 wherein each of the spacers encircles the post shank but not the post flange.

9. 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;
the body between a body front face and a body cable entry end;
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 separate from and interposed between the body front face and the nut flange;
the rearward spacer bearing on the body front face and on the nut trailing face; and,
the forward spacer electrically insulates the post flange from the nut flange.

10. The connector of claim 9 wherein the nut is electrically isolated from the post.

11. The connector of claim 9 wherein the forward spacer is an electrical insulator and the rearward spacer is an electrical conductor.

12. A male F-type coaxial cable connector comprising: a nut, body, and post arranged about a central axis;
the post including a shank and an end flange;
the nut rotatably coupled with the body via the post;
a body flange adjacent to a circumferential body groove, the groove in a plane normal to the central axis and the flange resiliently movable to narrow the groove; and,
a contact nub protruding from the body flange and operable to force the nut toward the post flange.

13. The connector of claim 12 further comprising a spacer between the post flange and the nut.
