Abstract

An adapter is disclosed for mounting on the mating end of a female slide on type coaxial connector to enable the direct mating between the latter and a male coupling type coaxial connector. More particularly, an adapter is disclosed which when mounted on a female slide on coaxial connector, results in a connector combination having a mating end with a configuration substantially similar to the configuration of a female, coupling type coaxial connector. The subject adapter is of generally elongated, cylindrical configuration having a mating end. The outer surface of the adapter is threaded, with the inner surface thereof including major and minor diameter portions separated by circumferential step. The minor diameter portion, which is disposed adjacent the mating end of the adapter, is configured to receive the mating end of the female, slide on coaxial connector. The major diameter portion of the adapter is threaded and is connectable to a threaded portion on the female slide on coaxial connector. In use, a direct interface is achieved between a female slide on coaxial connector and a male coupling type connector such that the high frequency characteristics of the connection are substantially maintained.

Claims

1. A coaxial connector comprising:

a connector member having a mating end and including a central conductor surrounded by a tubular insulator and a generally cylindrical outer conductor, said outer conductor having a threaded portion spaced from said mating end, said mating end including a plurality of longitudinally extending slits defining a plurality of cantilevered spring fingers, with the diameter of said mating end of said outer conductor being less than the diameter of said threaded portion; and

an adapter member of elongated, cylindrical configuration having a mating end, with the outer surface of said adapter being threaded, and with the inner surface thereof having major and minor diameter portions separated by a circumferential step, with the minor diameter portion being disposed adjacent the mating end thereof and having an inner diameter substantially corresponding to the outer diameter of said mating end of said conductor member, and with the major diameter portion, disposed at the opposed end of said adapter member, being threaded and adapted to engage with said threaded portion of said connector member, and wherein the mating end of said connector member is receivable within said adapter member, with the threaded portion of said connector member being threadably engaged with the threaded major diameter portion of said adapter member, such that the distal end of said threaded portion abuts said circumferential step of said adapter member whereby the configuration of the mating end of said connector member is altered.

2. A coaxial connector as recited in claim 1 wherein said circumferential step of said adapter member is disposed substantially perpendicular to the longitudinal axis of said adapter.

3. A coaxial connector as recited in claim 1 wherein the outer surface of said adapter member adjacent said opposed end is provided with a hexagonal configuration to facilitate the mounting of said adapter member on said connector member.

4. A coaxial connector as recited in claim 1 wherein the outer diameter of the threaded portion of said adapter member is equal to 0.250 inches.

5. A coaxial connector as recited in claim 1 wherein the diameter of said minor diameter portion of said adapter member is such that said cantilevered spring fingers of said connector member are compressed.

6. A coaxial connector as recited in claim 1 wherein said tubular insulator of said connector member is recessed from said mating end of said adapter member a distance of 0.076 inches.
