US 12,749,841 B2 · High frequency performance hardline connector

Abstract

A hardline connector for providing high frequency performance includes a body portion configured to be coupled with an interface port. The body portion is configured to house a collet and an insulator, the collet includes a pin portion and a gripping portion that is configured to receive a center conductor of a hardline coaxial cable, and the gripping portion is configured to define a forward facing surface at a forward end of the gripping portion of the collet. The body portion is configured to minimize peaks and valleys of impedance levels within the connector relative to a desired 75 ohm impedance such that the hardline connector is configured to improve return loss performance over a wider frequency bandwidth without degrading electrical, mechanical, and environmental performance of the connector by minimizing peaks and valleys of impedance levels within the connector relative to a desired 75 ohm impedance. The hardline connector is configured to achieve a return loss of −20 dB or better over a frequency range of 5 MHz to 3 GHz.

A hardline connector for providing high frequency performance comprising:

a front body assembly configured to be threadedly coupled with an interface port;
a mid body assembly configured to be threadedly coupled with the front body assembly;
a back nut assembly configured to be threadedly coupled with the mid body assembly;
wherein the front body assembly includes a front body housing, a collet, and a nonconductive collet insulator configured to electrically insulate the collet from the front body housing;
wherein the front body housing is configured to house the collet and the collet insulator;
wherein the collet includes a pin portion that is configured to extend through the collet insulator and extend from a forward end of the front body housing and a gripping portion that is configured to receive a center conductor of a hardline coaxial cable;
wherein the collet includes a stepped transition from the pin portion to the gripping portion that is configured to define a forward facing surface at a forward end of the gripping portion of the collet;
wherein the mid body assembly includes a mid body housing and a nonconductive seizure bushing;
wherein the mid body housing includes a forward end that is configured to be threadedly coupled with a rearward end of the front body housing and a rearward end that is configured to receive the hardline coaxial cable;
wherein a forward facing surface of the seizure bushing includes a plurality of fins that are configured to extend in the forward direction and to be received in a plurality of longitudinal grooves in an inner wall of the front body housing when the mid body housing is threadedly coupled with the front body housing such that the seizure bushing is prevented from rotating relative to the front body housing;
wherein a bore portion of the front body housing that surrounds the gripping portion of the collet includes a substantially constant inside diameter and the gripping portion of the collet includes a substantially constant outside diameter so as to minimize peaks and valleys of impedance levels within the connector relative to a desired 75 ohm impedance such that the hardline connector is configured to improve return loss performance over a wider frequency bandwidth without degrading electrical, mechanical, and environmental performance of the connector by minimizing peaks and valleys of impedance levels within the connector relative to a desired 75 ohm impedance;
wherein the collet insulator extends from a rearward facing surface of an end wall at the forward end of the front body housing to the forward facing surface at the forward end of the gripping portion of the collet without covering the gripping portion and includes radially spaced apart inner and outer cylindrical walls connected to one another at a forward end by a radial wall and configured to define a hollowed out region so as to minimize peaks and valleys of impedance levels within the connector relative to a desired 75 ohm impedance such that the hardline connector is configured to improve return loss performance over a wider frequency bandwidth without degrading electrical, mechanical, and environmental performance of the connector;
and
wherein the hardline connector is configured to achieve a return loss of −20 dB or better over a frequency range of 5 MHz to 6 GHz.
