Abstract

An electronic interconnect adapter for a bulkhead mounted high speed coaxial interconnect has a rotatable coupling bushing with a central bore. One side of the bushing has an axially extending flange disposed around the bore with the flange having a threaded interior surface that threadably mates with a threaded exterior surface of the female side of the coaxial interconnect. The opposite side of the bushing has an axially disposed cavity with a diameter greater than the central bore forming a shoulder within the cavity. A male side of the interconnect has a flange radially extending from a shield contact with a mating member extending through bore. A radial slot is formed in the cavity adjacent to the shoulder that receives a retaining member that captures the flange between the shoulder and the retaining member to secure the male side of the high speed coaxial interconnect to the coupling bushing.

Claims

1. An electronic interconnect adapter for a bulkhead mounted high speed coaxial interconnect having a female side mounted on the bulkhead and including a central signal conductor and a coaxial shield sleeve defining a chamber having a compliant contact facility portion with the sleeve having a threaded exterior surface comprising:

a male side of the high speed coaxial interconnect having a central signal conductor and a coaxial shield contact with the shield contact being divided into first and second mating members by an integrally formed and radially extending nut disposed part way along the shield contact with the first mating member having a threaded portion disposed between the nut and a mating portion having threads formed on the exterior surface thereof with the compliant contact facility portion of the female side chamber flexibly gripping the mating portion of the first mating member;

a circular washer having a central bore there through and a diameter equal to or greater than the maximum diameter of the integrally formed nut positioned on the first mating member in abutting relationship with the integral nut;

a retaining nut threadably mounted on the threaded portion of the first mating member that secures the washer on the male side of the coaxial interconnect;

a rotatable coupling bushing having a central bore that receives the male side of the high speed coaxial interconnect with one side of the bushing having an axially extending flange disposed around the bore with the flange having a threaded interior surface that threadably mates with the threaded exterior surface of the female side coaxial shield sleeve and the opposite side of the bushing having an axially disposed cavity with a diameter greater than the central bore forming a shoulder within the cavity that receives the circular washer on the shield contact and a radial slot formed in the cavity adjacent to the shoulder; and

a retaining member disposed in the radial slot that captures the circular washer between the shoulder and the retaining member to secure the male side of the high speed coaxial interconnect to the coupling bushing whereby the coupling bushing provides axial thrust of the first mating member into the chamber of the female side of the coaxial interconnect as the coupling bushing is threaded onto the coaxial shield sleeve.

2. The electronic interconnect adapter as recited in claim 1 wherein the second mating member is a SMA female interconnect.

3. The electronic interconnect adapter as recited in claim 1 wherein the second mating member is adapted to receive a coaxial cable.

4. The electronic interconnect adapter as recited in claim 1 wherein the coupling bushing is circular in form having a knurled exterior surface.

5. An electronic interconnect assembly comprising:

a high speed coaxial interconnect having a central signal conductor and a surrounding shield conductor with the interconnect having a male side and a female side;

the female side being mountable on a bulkhead and including a central signal conductor and a coaxial shield sleeve defining a chamber having a compliant contact facility portion with the sleeve having a threaded exterior surface;

the male side of the high speed coaxial interconnect having a central signal conductor and a coaxial shield contact with the shield contact being divided into first and second mating members by an integrally formed and radially extending nut disposed part way along the shield contact with the first mating member having a threaded portion with threads formed on the exterior surface thereof disposed between the nut and a mating portion with the compliant contact facility portion of the female side chamber flexibly gripping the mating portion of the first mating member;

a circular washer having a central bore there through and a diameter equal to or greater than the maximum diameter of the integrally formed nut positioned on the first mating member in abutting relationship with the integral nut;

a retaining nut threadably mounted on the threaded portion of the first mating member that secures the washer on the male side of the coaxial interconnect;

a rotatable coupling bushing having a central bore that receives the male side of the high speed coaxial interconnect with one side of the bushing having an axially extending flange disposed around the bore with the flange having a threaded interior surface that threadably mates with the threaded exterior surface of the female side coaxial shield sleeve and the opposite side of the bushing having an axially disposed cavity with a diameter greater than the central bore forming a shoulder within the cavity that receives the circular washer on the shield contact and a radial slot formed in the cavity adjacent to the shoulder; and

a retaining member disposed in the radial slot that captures the circular washer between the shoulder and the retaining member to secure the male side of the high speed coaxial interconnect to the coupling bushing whereby the coupling bushing provides axial thrust of the first mating member into the chamber of the female side of the coaxial interconnect as the coupling bushing is threaded onto the coaxial shield sleeve.

6. The electronic interconnect assembly as recited in claim 5 wherein the second mating member is a SMA female interconnect.

7. The electronic interconnect assembly as recited in claim 5 wherein the second mating member is adapted to receive a coaxial cable.

8. The electronic interconnect assembly as recited in claim 5 wherein the coupling bushing is circular in form having a knurled exterior surface.
