Abstract

An assembly includes: first and second printed circuit boards (PCBs), the PCBs being disposed generally parallel to each other; a first coaxial connector mounted to the first PCB, the first coaxial connector comprising a first inner contact and a first outer connector body, the first outer connector body having a first thickness; and a second coaxial connector mounted to the second PCB, the second axial connector comprising, a second inner contact and a second outer connector body. The second outer connector body includes an engagement surface, the engagement surface being flexible in a direction normal to the second PCB, the engagement surface having a second thickness that is greater than the first thickness.

Claims (27)

1. An assembly comprising:

first and second printed circuit boards (PCBs), the PCBs being disposed generally parallel to each other;

a first coaxial connector mounted to the first PCB, the first coaxial connector comprising a first inner contact and a first outer connector body, the first outer connector body having a first thickness; and

a second coaxial connector mounted to the second PCB, the second axial connector comprising a second inner contact and an engagement surface, the second inner contact engaging the first inner contact, the engagement surface being flexible in a direction normal to the second PCB, the engagement surface having a second thickness that is greater than the first thickness, the engagement surface engaging the first outer connector body.

2. The assembly defined in claim 1 , wherein the second outer connector body comprises a conductive gasket.

3. The assembly defined in claim 1 , wherein the second outer conductor body comprises a raised contact pad.

4. The assembly defined in claim 1 , wherein the first inner contact has a tapered free end, and the second inner contact has a splayed free end.

5. The assembly defined in claim 1 , wherein the first inner contact is configured such that a free end thereof can retract and extend axially relative to the first PCB.

6. The assembly defined in claim 5 , wherein the first inner contact can be secured into a retracted position.

7. The assembly defined in claim 4 , wherein the second outer conductor body comprises one of a conductive gasket and a raised contact pad.

8. The assembly defined in claim 5 , wherein the second outer conductor body comprises one of a conductive gasket and a raised contact pad.

9. An assembly comprising:

first and second printed circuit boards (PCBs), the PCBs being disposed generally parallel to each other;

a first coaxial connector mounted to the first PCB, the first coaxial connector comprising a first inner contact and a first outer connector body having a free end surface with a first thickness; and

a second coaxial connector mounted to the second PCB, the second axial connector comprising a second inner contact and an engagement surface, the second inner contact engaging the first inner contact, the engagement surface having a second thickness that is greater than the first thickness; and

wherein the first outer connector body is configured to bow radially under axial compression induced by engagement between the free end surface of the first outer connector body and the engagement surface of the second outer connector body.

10. The assembly defined in claim 9 , wherein the first inner contact has a tapered free end, and the second inner contact has a splayed free end.

11. The assembly defined in claim 9 , wherein the first inner contact is configured such that a free end thereof can retract and extend axially relative to the first PCB.

12. The assembly defined in claim 11 , wherein the first inner contact can be secured into a retracted position.

13. An assembly comprising:

first and second printed circuit boards (PCBs), the PCBs being disposed generally parallel to each other;

a first coaxial connector mounted to the first PCB, the first coaxial connector comprising a first inner contact and a first outer connector body having a free end surface with a first thickness; and

a second coaxial connector mounted to the second PCB, the second axial connector comprising a second inner contact and an engagement surface, the second inner contact engaging the first inner contact, the engagement surface having a second thickness that is greater than the first thickness; and

wherein the first outer connector body is configured to be arcuate in cross-section, such that the outer connector body deflects under axial compression induced by engagement between the free end surface of the first outer connector body and the engagement surface of the second outer connector body to provide axial float to the engaged connectors.

14. The assembly defined in claim 13 , wherein the first inner contact has a tapered free end, and the second inner contact has a splayed free end.

15. The assembly defined in claim 13 , wherein the first inner contact is configured such that a free end thereof can retract and extend axially relative to the first PCB.

16. The assembly defined in claim 15 , wherein the first inner contact can be secured into a retracted position.
