Abstract

A coaxial connector assembly includes a housing holding an outer contact and a dielectric holder received in the outer contact. The dielectric holder has a mating segment having a front cavity and a cable segment having a cable cavity receiving a cable assembly. The cable assembly has a pin contact. A center contact is received in the front cavity of the dielectric holder. The center contact has a base positioned in the dielectric holder generally at an intersection of the front cavity and the cable cavity. The center contact has deflectable pin beams extending from the base. The pin beams have flared lead-in tips at distal ends of the beams. The base and the pin beams are axially aligned with the cable axis to receive the pin contact.

First claim

1 . A coaxial connector assembly comprising:
a housing holding an outer contact; a dielectric holder received in the outer contact, the dielectric holder having a mating segment and a cable segment orthogonal to the mating segment, the mating segment having a front cavity extending along a mating axis, the cable segment having a cable cavity extending along a cable axis; a cable assembly received in the cable cavity of the dielectric holder, the cable assembly having a pin contact configured to be terminated to an end of a center conductor of a cable, the pin contact having a tip; and a center contact received in the front cavity of the dielectric holder, the center contact having a base and a mating portion extending forward of the base, the base positioned in the dielectric holder generally at an intersection of the front cavity and the cable cavity, the center contact having deflectable pin beams extending from the base configured to deflect outward when mated with the pin contact, the pin beams having flared lead-in tips at distal ends of the beams, the base and the pin beams being axially aligned with the cable axis to receive the pin contact, the pin beams including slots with beam arms on both sides of the slots, the slots and the beam arms extending along the cable axis between the distal ends and the base, the pin beams being flexed at the beam arms.

2 . The coaxial connector assembly of claim 1 , wherein the pin beams extend toward the cable assembly from the base.

3 . The coaxial connector assembly of claim 1 , wherein the pin beams include separable mating interfaces configured to engage and electrically connect to the pin contact.

4 . The coaxial connector assembly of claim 1 , wherein the lead-in tips are flared outward away from the pin contact.

5 . The coaxial connector assembly of claim 1 , wherein the pin beams include mating segments, the lead-in tips being flared outward from the mating segments such that the pin beams have a first separation distance between the mating segments and a second separation distance between the distal ends greater than the first separation distance.

6 . The coaxial connector assembly of claim 1 , wherein the base has a first thickness, the pin beams having a second thickness less than the first thickness.

7 . (canceled)

8 . The coaxial connector assembly of claim 1 , wherein the base has an opening axially aligned with the cable axis, the opening receiving the tip of the pin contact.

9 . The coaxial connector assembly of claim 8 , wherein the opening is bounded by a strain relief surface, the strain relief surface configured to engage and locate the pin contact to prevent overstress of the pin beams.

10 . The coaxial connector assembly of claim 1 , wherein the dielectric holder includes an expansion slot that receives the base and the pin beams of the center contact, the pin beams being deflectable into the expansion slot, the dielectric holder including a guide opening in the cable cavity open to the expansion slot, the guide opening receiving the pin contact and guiding the pin contact into mating with the pin beams.

11 . The coaxial connector assembly of claim 10 , wherein the lead-in tips having a wider catch area than the guide opening to receive the pin contact.

12 . The coaxial connector assembly of claim 1 , wherein the dielectric holder includes a pocket above the base, the pocket receiving the tip of the pin contact when the pin contact is plugged into the center contact.

13 . The coaxial connector assembly of claim 1 , wherein the front cavity is open at a rear of the dielectric holder to receive the center contact through the rear of the dielectric holder.

14 . A coaxial connector assembly comprising:
a housing holding an outer contact; a dielectric holder received in the outer contact, the dielectric holder having a mating segment and a cable segment orthogonal to the mating segment, the mating segment having a front cavity extending along a mating axis, the cable segment having a cable cavity extending along a cable axis; a cable assembly received in the cable cavity of the dielectric holder, the cable assembly having a pin contact configured to be terminated to an end of a center conductor of a cable, the pin contact having a tip; and a center contact received in the front cavity of the dielectric holder, the center contact having a base and a mating portion extending forward of the base, the base positioned in the dielectric holder generally at an intersection of the front cavity and the cable cavity, the center contact having deflectable pin beams extending from the base, the base and the pin beams being axially aligned with the cable axis to receive the pin contact, the pin beams being configured to deflect outward when mated with the pin contact, the base having a first thickness, the pin beams having a second thickness less than the first thickness.

15 . The coaxial connector assembly of claim 14 . wherein the pin beams extend toward the cable assembly from the base.

16 . The coaxial connector assembly of claim 14 , wherein the pin beams include slots with beam arms on both sides of the slots, the pin beams being flexed at the beam arms.

17 . The coaxial connector assembly of claim 14 , wherein the base has an opening axially aligned with the cable axis, the opening receiving the tip of the pin contact, the opening being bounded by a strain relief surface, the strain relief surface configured to engage and locate the pin contact to prevent overstress of the pin beams.

18 . The coaxial connector assembly of claim 14 , wherein the dielectric holder includes an expansion slot that receives the base and the pin beams of the center contact, the pin beams being deflectable into the expansion slot, the dielectric holder including a guide opening in the cable cavity open to the expansion slot, the guide opening receiving the pin contact and guiding the pin contact into mating with the pin beams.

19 . A coaxial connector assembly comprising:
a housing holding an outer contact; a dielectric holder received in the outer contact, the dielectric holder having a mating segment and a cable segment orthogonal to the mating segment, the mating segment having a front cavity extending along a mating axis, the cable segment having a cable cavity extending along a cable axis, the dielectric holder including a guide opening in the cable cavity open to the front cavity, the guide opening being aligned with the cable axis; a cable assembly received in the cable cavity of the dielectric holder, the cable assembly having a pin contact configured to be terminated to an end of a center conductor of a cable, the pin contact having a tip, the tip of the pin contact being loaded through the guide opening; and a center contact received in the front cavity of the dielectric holder, the center contact having a base and a mating portion extending forward of the base, the base positioned in the dielectric holder above the guide opening, the center contact having deflectable pin beams extending from the base configured to deflect outward when mated with the pin contact, the pin beams having flared lead-in tips at distal ends of the beams, the base and the pin beams being axially aligned with the guide opening to receive the pin contact, the flared lead-in tips having a larger catch area than a diameter of the guide opening.
