Abstract

A 4.3/10 coaxial connector configured to receive a mating 4.3/10 connector includes: an inner contact: a dielectric spacer; and an outer contact, the dielectric spacer separating the inner contact and the outer contact. The outer contact includes an outer wall and a plurality of spring fingers, the spring fingers configured to deflect radially inwardly when the mating 4.3/10 connector is mated. The connector further comprises blocking structure that prevents mating of a Mini-Din connector.

First claim

What which is claimed is:

1 . A similar interface blocking coaxial connector, interconnectable with a mating coaxial connector, comprising:
an inner contact defining a longitudinal axis; a cylindrical outer contact with an axially-extending outer body and a plurality of spring fingers positioned radially inward of the outer body; and a dielectric sleeve positioned between the inner contact and the spring fingers, the sleeve having a stop face that is substantially aligned with distal ends of the spring fingers, such that the sleeve interferes with an outer conductor cylinder of a mismating connector.

2 . The connector defined in claim 1 , wherein the sleeve has an outer diameter proximate an inner diameter of the spring fingers.

3 . The connector defined in claim 1 , wherein the sleeve includes a plurality of spokes.

4 . The connector defined in claim 1 , wherein the connector is a 4.3/10 connector, and the mismating connector is a Mini-Din connector.

5 . The connector defined in claim 1 , wherein an inner diameter of the sleeve is adjacent an outer diameter of the inner contact.

6 . The connector defined in claim 1 , wherein the inner contact comprises a plurality of spring fingers.

7 . A 4.3/10 coaxial connector configured to receive a mating 4.3/10 connector, comprising:
an inner contact; an, outer contact; the outer contact including an axially-extending outer body, and a plurality of spring fingers positioned radially inwardly of the outer body, the spring fingers configured to deflect radially inwardly when the mating 4.3/10 connector is mated; further comprising a dielectric sleeve separating the inner contact and the outer contact, wherein the sleeve is configured to prevent radially-outward splaying of the spring fingers when a Mini-Din connector is mismated with the connector.

8 . The connector defined in claim 7 , wherein the sleeve has an outer diameter proximate an inner diameter of the spring fingers.

9 . The connector defined in claim 7 , wherein the sleeve includes a plurality of spokes,

7 . connector defined in claim 7 , wherein the sleeve extends forwardly a sufficient distance that a stop face of the sleeve is substantially aligned with distal ends of the spring fingers.

11 . The connector defined in claim 7 , wherein an inner diameter of the sleeve is adjacent an outer diameter of the inner contact.

12 . The connector defined in claim 7 , wherein the inner contact comprises a plurality of spring fingers.

13 . A similar interface blocking coaxial connector, interconnectable with a mating coaxial connector, comprising an inner contact;
an outer contact; the outer contact including an axially-extending outer body and a plurality of spring fingers positioned radially inwardly of the outer body, the spring fingers configured to deflect radially inwardly when the mating, connector is mated; further comprising a dielectric sleeve separating the inner contact and the outer contact, wherein the sleeve is configured to prevent radially-outward splaying of the spring fingers when a mismating connector is mismated with the connector.

14 . The connector defined in claim 13 , wherein the sleeve has an outer diameter proximate an inner diameter of the spring fingers.

15 . The connector defined in claim 13 , wherein the sleeve includes a plurality of spokes.

16 . The. connector defined in claim 13 , wherein the sleeve extends forwardly a sufficient distance that a stop face of the sleeve is substantially aligned with distal ends of the spring fingers.

17 . The connector defined in claim 13 , wherein an inner diameter of the sleeve is adjacent an outer diameter of the inner contact.

18 . The connector defined in claim 13 , wherein the inner contact comprises a plurality of spring fingers.
