Abstract

A fixture for holding a whip antenna element in position outside a cabinet housing a television set or the like is assembled with the cabinet by snapping it into place within an aperture in a wall of the cabinet. The fixture allows replacement of the antenna element from outside the cabinet.

Claims

1. In an apparatus of the class described, a one-piece insulated housing having upper and lower portions, said housing lower portion being of generally cylindrical configuration and adapted to be received within an aperture in a supporting wall, said housing lower portion having a plurality of resilient tabs normally extending outwardly from said lower housing portion but adapted to be temporarily moved inwardly against aperturedefining portions of said wall in the course of inserting said housing lower portion in said wall aperture, said housing upper portion having a centrally-apertured cover detachably connected to said housing upper portion, an antenna element having an a enlarged portion, at least the lower portion of said enlarged antenna portion being disposed in said housing upper portion;

and a conductive member positioned within said housing, one end of said conductive member being in electrical contact with said antenna element and the other end of said conductive member projecting from said lower housing portion.

2. Apparatus according to claim 1, wherein the upper portion of said housing has external threads, and said cover comprises a tubular body having cooperating internal threads, whereby said cover is removably secured in fixed relation to said housing.

3. Apparatus according to claim 2, wherein said cover includes an inwardly extending flange at the extremity of said tubular body, the inner extremity of said flange defining said centrally disposed aperture, and including a ball retainer having a curved surface portion and a flange portion, said curved surface portion being adapted to engage the enlarged portion of said antenna element, and the flange portion of said ball retainer being adapted to be retained in position by the flange of said cover.

4. Apparatus according to claim 2, wherein the exterior threads provided on said upper portion of said housing are adapted to engage one surface of said wall and said tabs being adapted to engage the opposite surface of said wall.

5. Apparatus according to claim 1, wherein said housing is provided with a flange protruding outwardly therefrom, said flange being adapted to engage one surface of said wall, and said tabs being adapted to engage the opposite surface of said wall.

6. Apparatus according to claim 1, wherein said conductive member comprises a conductive ferrule, and including resiliant means for urging said ferrule into electrical contact with said antenna element, and electrically conductive means connected with the end of said ferrule remote from said antenna element.

7. Apparatus according to claim 6, wherein said electrically conductive means comprises a pair of cooperating connectors adapted for releasably completing an electrical connection with said ferrule.

8. Apparatus according to claim 1, including a key provided on said lower portion of said housing, said wall being provided with a notch adjacent to the aperture in said wall for receiving said key and preventing said housing from rotating relative to said wall.

9. Apparatus according to claim 1, wherein said upper and lower portions of said housing are integrally formed of plastic material.

10. Apparatus according to claim 1, wherein said cover has a portion of its outer surface formed with a regular polygonal cross-section.
