Abstract

A connector assembly includes an outer contact and a cavity insert. The outer contact has a mating segment, a terminating segment, and a middle segment therebetween. The mating segment is configured to engage a mating outer contact of a mating connector assembly. The terminating segment is configured to be terminated to a cable. The cavity insert surrounds the middle segment of the outer contact. The cavity insert has an overmold body. An interior surface of the overmold body engages an exterior surface of the outer contact and follows contours of the exterior surface along the middle segment.

First claim

What is claimed is:

1. A connector assembly comprising:
an outer contact having a mating segment, a terminating segment, and a middle segment therebetween, the mating segment configured to engage a mating outer contact of a mating connector assembly, the terminating segment configured to be terminated to a cable;
a cavity insert surrounding the middle segment of the outer contact, the cavity insert having an overmold body, an interior surface of the overmold body engaging an exterior surface of the outer contact and following contours of the exterior surface along the middle segment; and
an outer housing defining a cavity, the outer contact and the cavity insert held within the cavity of the housing, the cavity insert engaging an inner surface of the outer housing to secure an axial position of the outer contact within the cavity of the outer housing;
wherein the middle segment of the outer contact has an outer diameter that is less than an outer diameter of the mating segment and is less than an outer diameter of the terminating segment, wherein an inner diameter of the cavity insert defined by the interior surface of the overmold body is less than the respective outer diameters of the mating segment and the terminating segment.

2. The connector assembly of claim 1 , wherein the terminating segment of the outer contact is integrally fixed to a carrier strip that holds at least one other outer contact at a spaced apart location from the outer contact of the connector assembly.

3. The connector assembly of claim 1 , wherein the overmold body of the cavity insert is seamless.

4. The connector assembly of claim 1 , wherein the outer contact includes at least one securing feature along the middle segment, each securing feature being a protrusion or a depression extending from the exterior surface, the interior surface of the overmold body following the contours of each securing feature to rotationally and axially secure the cavity insert to the outer contact.

5. The connector assembly of claim 1 , wherein the outer contact defines a channel that receives a dielectric body and a center contact therein, the middle segment of the outer contact defining at least one of a seam or a hole extending through a thickness of the outer contact and fluidly coupled to the channel,
wherein the connector assembly further includes a filling layer disposed along the middle segment between the exterior surface of the outer contact and the interior surface of the cavity insert, the filling layer plugging the at least one of the seam or the hole to prohibit the overmold body of the cavity insert from extending therethrough.

6. The connector assembly of claim 1 , wherein a substantial entirety of the interior surface of the overmold body engages the exterior surface of the outer contact.

7. The connector assembly of claim 1 , wherein the outer contact defines a channel that receives a dielectric body and a center contact therein, the center contact, the dielectric body, the outer contact, and the cavity insert together defining a contact subassembly that is received within the cavity of the outer housing, the overmold body of the cavity insert defining at least one flange extending radially outward from an exterior surface of the cavity insert, the at least one flange used to retain an axial position of the contact subassembly within the cavity of the outer housing.

8. The connector assembly of claim 1 , wherein the middle segment of the outer contact has a cylindrical shape, the overmold body of the cavity insert being molded in situ on the exterior surface of the outer contact along a perimeter of the middle segment.

9. The connector assembly of claim 1 , wherein the outer contact is composed of a metal material and the cavity insert is composed of a thermoplastic material.

10. The connector assembly of claim 1 , wherein the outer contact includes a seam that extends a length through the mating segment, the middle segment, and the terminating segment, the seam being defined by first and second ends of the outer contact, the first and second ends being spaced apart from each other to define a gap along the terminating segment, a size of the gap between the first and second ends configured to be reduced responsive to terminating the terminating segment to the cable.

11. A connector assembly comprising:
a center contact;
a dielectric body surrounding the center contact;
an outer contact surrounding the dielectric body and the center contact, the outer contact having a cylindrical shape and defining a channel that receives the dielectric body and the center contact therein, the outer contact including a mating segment, a terminating segment, and a middle segment disposed therebetween, the mating segment configured to engage a mating outer contact of a mating connector assembly, the terminating segment configured to be terminated to a cable, the terminating segment being integrally fixed to a carrier strip, the carrier strip holding at least one other outer contact at a spaced apart location from the outer contact of the connector assembly; and
a cavity insert surrounding the middle segment of the outer contact, the cavity insert having an overmold body, an interior surface of the overmold body engaging an exterior surface of the outer contact and following contours of the exterior surface along the middle segment,
wherein an outer diameter of the mating segment of the outer contact is greater than an outer diameter of the middle segment and an inner diameter of the cavity insert that is defined by the interior surface of the overmold body;
wherein the outer contact includes a filling layer disposed on the middle segment between the exterior surface of the outer contact and the interior surface of the cavity insert, the filling layer plugging at least one of a seam or a hole in the outer contact to prohibit the overmold body of the cavity insert from extending through the at least one of the seam or the hole.

12. The connector assembly of claim 11 , wherein the outer contact includes at least one securing feature along the middle segment, each securing feature being a protrusion or a depression extending from the exterior surface, the interior surface of the overmold body following the contours of each securing feature to rotationally and axially secure the cavity insert to the outer contact.

13. The connector assembly of claim 11 , wherein the overmold body of the cavity insert is seamless and is composed of a thermoplastic material.
