Abstract

A blindmate interconnect coaxial connector includes a center conductor, a thermally-conductive dielectric surrounding the center conductor, and an outer tubular conductor surrounding the dielectric. The dielectric transfers heat from the center conductor to the outer conductor, and the outer conductor includes heat transfer fins to radiate such heat. The center conductor is formed by first and second halves which mate within the axial bore of the dielectric. The outer conductor is formed of two mating sections. The center conductor and surrounding dielectric are inserted within the first mating section, and the second mating section is then mated with the first section to complete the assembly of the connector.

Claims

1-15. -15. (canceled)

16. A method of assembling a coaxial connector used to join two coaxial members, said method comprising the steps of:

a. providing a center conductor comprising first and second mating halves, the first half of the center conductor including a female socket for receiving a male pin of a first mating member, and the second half of the center conductor including a female socket for receiving a male pin of a second mating member;

b. providing a dielectric with an axial bore extending therethrough between first and second opposing ends;

c. providing a hollow tubular outer conductor;

d. inserting the first half of the center conductor within the first end of the axial bore of the dielectric;

e. inserting the second half of the center conductor within the second end of the axial bore of the dielectric, and coupling the first and second halves of the center conductor together to extend along a common axis; and

f. inserting the center conductor and dielectric within the hollow tubular outer conductor, wherein at least a portion of said dielectric physically contacts the outer conductor to provide a thermally conductive path therebetween.

17. The method recited by claim 16 wherein step c. includes providing the hollow tubular outer conductor as first and second mating sections.

18. The method recited by claim 17 wherein step f. includes the steps of:

g. inserting the center conductor, including the dielectric, within the first section of the outer conductor; and

h. thereafter engaging the second section of the outer conductor over the assembly formed in step g.

28. The method recited by claim 16 wherein said dielectric is comprised of reinforced fluoropolymer.

29. The method recited by claim 16 wherein the dielectric has a thermal conductivity of 0.75 W/(m-°

K) or more.

30. The method recited by claim 16 wherein the center conductor, the dielectric, and the outer conductor share a common longitudinal axis.

31. The method recited by claim 16 wherein thermal grease is disposed between the center conductor and the dielectric member.

32. The method recited by claim 16 wherein thermal grease is disposed between the outer conductor and the dielectric member.
