Coaxial connector with axial and radial contact between outer conductors
An assembly of mated coaxial connectors includes: a first connector with a first central conductor extension and a first outer conductor extension having a free end portion; and a second connector with a second central conductor extension and a second outer conductor extension having an outer body and an inner body with a gap therebetween. The first central conductor extension engages the second central conductor extension. The free end portion of the first outer conductor extension fits within the gap of the second outer conductor extension, such that the inner body applies radially outward pressure to the first outer conductor extension. At least one of the first outer conductor extension and the second outer conductor extension includes a flex member that deflects during axial engagement of the first and second connectors to apply axial pressure to the other of the first outer conductor extension and the second outer conductor extension.
1. An assembly of mated coaxial connectors, comprising:
a first connector having a first central conductor extension, a dielectric radially outward of the first central conductor extension, and a first outer conductor extension radially outward of the dielectric, the first outer conductor extension having a free end portion;
a second connector having a second central conductor extension and a second outer conductor extension, the second outer conductor extension having an outer body and an inner body with a gap therebetween;
wherein the first central conductor extension engages the second central conductor extension to establish a first electrical connection;
wherein the free end portion of the first outer conductor extension fits within the gap of the second outer conductor extension, such that the inner body applies radially outward pressure to the first outer conductor extension to establish a second electrical connection; and
wherein the first connector further includes an annular insert that resides radially inwardly of the free end portion of the first outer conductor extension and radially outward of the dielectric, the annular insert including a flexible body and a contact surface that engages a free end of the inner body to apply axial pressure thereto.
2. The assembly defined in claim 1 , wherein the second outer conductor extension also includes a flex member that deflects during axial engagement.
3. The assembly defined in claim 2 , wherein the outer body of the second outer conductor extension does not axially engage the first outer conductor extension.
4. The assembly defined in claim 1 , wherein the inner body of the second outer conductor extension includes a plurality of axially-extending fingers, the fingers applying radial pressure to the first outer conductor extension and axial pressure to the contact surface of the annular insert.
5. The assembly defined in claim 4 , wherein the second outer conductor extension also includes a flex member that deflects during axial engagement, and wherein the inner body of the second outer conductor extension comprises a radially-extending flex section on which the plurality of axially-extending fingers are mounted, and wherein the flex section serves as the flex member of the second outer conductor extension.
6. The assembly defined in claim 1 , wherein the annular insert includes a plurality of fingers, wherein free ends of the fingers provide the contact surface.
7. The assembly defined in claim 6 , wherein the fingers contact an inner surface of the free end portion of the first outer conductor extension.
