Abstract

A coaxial interconnect and contact are provided. The coaxial contact is patterned to define a plurality of openings along its longitudinal length. An inner surface of the contact may circumferentially engage an outer surface of a mating contact, wherein such engagement causes at least a portion of the contact to flex radially outwardly. The contact may also flex in the longitudinal or axial direction.

Claims

1. A blind mate interconnect for connecting to a coaxial transmission medium to form an electrically conductive path between the transmission medium and the blind mate interconnect, the blind mate interconnect comprising:

a contact adapted for receiving a coaxial transmission medium extending circumferentially about a longitudinal axis, the contact including a main body, the main body having a proximal portion and a distal portion, a first end and an opposing second end, the first end disposed on the proximal portion and the second end disposed on the distal portion, the contact comprising an electrically conductive material;

an insulator circumferentially disposed about the contact, the insulator including a first insulator component and a second insulator component, the components cooperating to receive the contact, the components including at least one insulator flange; and

an outer conductor circumferentially disposed about the insulator, the outer conductor including a first end, a second end opposite the first end and a tubular body therebetween, the ends having at least one radial array of substantially helical slots starting at the first end and radially extending from an outer surface to an inner surface, the slots extending helically from the end along the tubular body for a distance, the slots delineating at least one array of substantially helical cantilevered beams, the helical cantilevered beams having at least a free end and a fixed end, the tubular body having at least one radial array of sinuate cuts, the cuts delineating at least one radial array of sinuate sections, the sinuate sections cooperating with the at least one array of substantially helical cantilevered beams to compensate for misalignment within a coaxial transmission medium, the conductor comprising an electrically conductive material.

2. The blind mate interconnect of claim 1, the substantially helical cantilevered beams each having at least one retention finger at the free end of the cantilevered beams.

3. The blind mate interconnect of claim 2, the retention finger adapted to radially flex independently of the cantilevered beams.

4. The blind mate interconnect of claim 1, the substantially helical cantilevered beams each having at least one insulator flange stop.

5. The blind mate interconnect of claim 1, the substantially helical slots each defining at least one flange receptacle for receiving the at least one insulator flange, the at least one flange receptacle comprising a radial array of flange receptacles.

6. The blind mate interconnect of claim 1, the helical slots being less than 90 degrees relative to the longitudinal axis.

7. The blind mate interconnect of claim 6, the helical slots being from about 30 degrees to about 60 degrees relative to the longitudinal axis.

8. The blind mate interconnect of claim 6, the helical slots being from about 40 degrees to about 50 degrees relative to the longitudinal axis.

9. The blind mate interconnect of claim 1, the outer conductor being able to compensate for mating misalignment between a mating pair of coaxial transmission mediums.

10. The blind mate interconnect of claim 9, the outer conductor being able to compensate for mating misalignment, the compensation including one or more of radially expanding, radially contracting, axially compressing, axially stretching, bending, flexing, or combinations thereof.

11. The blind mate interconnect of claim 1, the outer conductor including at least one radial array of substantially helical slots starting at the first end and at least one radial array of substantially helical slots starting at the second end, the slots radially extending from an outer surface to an inner surface, the slots extending helically from both ends along the tubular body for a distance, the slots delineating at least two arrays of substantially helical cantilevered beams.

12. An outer conductor for a blind mate interconnect, the outer conductor comprising:

a first end;

a second end opposite the first end;

a tubular body between the first end and the second end;

at least one radial array of substantially helical slots starting at the first end and radially extending from an outer surface to an inner surface, the slots extending helically from the end along the tubular body for a distance, the slots delineating at least one array of substantially helical cantilevered beams, the helical cantilevered beams having at least a free end and a fixed end, the tubular body having at least one radial array of sinuate cuts, the cuts delineating at least one radial array of sinuate sections, the sinuate sections cooperating with the at least one array of substantially helical cantilevered beams to compensate for misalignment within a coaxial transmission medium, the conductor comprising an electrically conductive material.
