Abstract

A coaxial connector assembly is described herein. The coaxial connector assembly includes an inner contact that is configured to terminate a center conductor of a coaxial cable, an insulative inner sleeve holding the inner contact, a tubular outer contact surrounding the inner sleeve and the inner contact, said outer contact configured to terminate a shield braid of the coaxial cable and an insulative cylindrical outer sleeve defining a central cavity extending longitudinally therethrough in which said outer contact is disposed. The cavity has an opening configured to receive a corresponding coaxial connector. A lip on a forward end of the outer sleeve extends into the opening such that a forward edge of the outer contact is not exposed within the opening. The coaxial connector assembly may be configured to meet the FAKRA connector standards.

First claim

We claim:

1. A coaxial connector assembly, comprising:
an inner contact configured to terminate a center conductor of a coaxial cable;
an insulative inner sleeve holding the inner contact;
a tubular outer contact surrounding the inner sleeve and the inner contact, said outer contact configured to terminate a shield braid of the coaxial cable, wherein the outer contact defines a pair of lock tabs, each lock tab of the pair of lock tabs protruding from opposite sides of an outer surface of the outer contact;
an insulative cylindrical outer sleeve defining a central cavity extending longitudinally therethrough in which said outer contact is disposed, wherein said cavity has an opening configured to receive a corresponding coaxial connector and wherein a lip on a forward end of the outer sleeve extends into the opening such that a forward edge of the outer contact is not exposed within the opening, wherein the outer sleeve defines a pair of apertures, each aperture of the pair of apertures extending radially from the cavity to the outer surface through opposite sides of the outer sleeve in which one of the pair of lock tabs is received and wherein the outer sleeve defines a pair of longitudinal slots, each slot of the pair of slots extending radially through opposite sides of the outer sleeve and each slot intermediate the pair of apertures, said pair of slots configured to allow sides of the outer sleeve to flex outwardly; and
a connector housing in which the outer sleeve is received and wherein the connector housing inhibits the sides of the outer sleeve from flexing outwardly.

2. The coaxial connector assembly according to claim 1 , wherein the lip is angled inwardly toward the opening.

3. A female coaxial connector assembly, comprising:
an inner contact configured to terminate a center conductor of a coaxial cable;
an inner sleeve formed of a first dielectric material and holding the inner contact;
a tubular outer contact formed from a flat work piece and surrounding the inner sleeve and the inner contact, said outer contact configured to terminate a shield braid of the coaxial cable; and
a cylindrical outer sleeve formed of a second dielectric material and defining a longitudinal cavity extending therethrough, wherein said outer contact is disposed within said cavity, wherein said cavity has an opening configured to receive a corresponding male coaxial connector, and wherein a lip on a forward end of the outer sleeve angled inwardly toward the opening and extending into the opening such that a forward edge of the outer contact is not exposed within the opening, wherein a pair of lock tabs is formed from the flat work piece, each lock tab of the pair of lock tabs protruding from opposite sides of the outer contact, wherein the outer sleeve defines a pair of apertures, each aperture of the pair of apertures extending radially from the cavity to the outer surface through opposite sides of the outer sleeve in which one of the pair of lock tabs is received, and wherein a rearward edge of the lock tab engages a forward edge of the aperture, thereby inhibiting removal of the outer contact from the outer sleeve, and wherein the outer sleeve defines a pair slots extending longitudinally from a rearward flange of the outer sleeve, each slot of the pair of slots extending radially through opposite sides of the outer sleeve and each slot intermediate the pair of apertures, said pair of slots configured to allow sides of the outer sleeve to flex outwardly when a forward surface of the lock tabs engage the rearward flange of the outer sleeve.

4. The female coaxial connector assembly according to claim 3 , further comprising a connector housing in which the outer sleeve is received and wherein the connector housing inhibits the sides of the outer sleeve from flexing outwardly, thereby retaining the pair of lock tabs within the pair of apertures.
