Coaxial cable connector with multi-contact to ensure establishment of ground loop

摘要

A coaxial cable connector includes a connector body including a barrel, a plastic bushing mounted in the barrel, a body shell inserted into one end of the barrel and abutted against the plastic bushing, an inner tube inserted through the body shell into the barrel defining an end flange and a shoulder, a locknut having an annular groove attached to a neck of the body shell, an inside retaining hole forced into engagement with the shoulder of the inner tube and an abutment surface abutted against the end flange of the inner tube, and an annular contact spring plate set in the inside retaining hole of the locknut with multiple spacer strips thereof clamped on the shoulder of the inner tube to ensure positive establishment of the desired ground loop.

1. A coaxial cable connector, comprising a connector body connected to one end of a coaxial cable, a locknut for locking said connector body to a mating device, and an annular contact spring plate set between said connector body and said locknut, wherein:
said connector body comprises a barrel, a plastic bushing mounted in said barrel, a body shell inserted into one end of said barrel and abutted against said plastic bushing, said body shell comprising an axial hole and a neck located on one end thereof around said axial hole, an inner tube inserted through said axial hole of said body shell into the inside of said barrel, said inner tube comprising an end flange radially extended around the periphery of one end thereof, an abutment surface located on an inner side of said end flange and a shoulder located on the periphery thereof near the abutment surface of said inner tube and kept in contact with said neck of said body shell; said locknut is attached to one end of said inner tube and one end of said body shell, comprising an annular groove attached to the neck of said body shell, an inside retaining hole forced into engagement with said shoulder of said inner tube, and an abutment surface connected to one end of said inside retaining hole and abutted against the abutment surface of said inner tube; said annular contact spring plate is set between the shoulder of said inner tube and said inside retaining hole of said locknut, comprising an annular body having a predetermined axial width and positioned in said inside retaining hole of said locknut and a plurality of spacer strips extended from said annular body thereof and clamped on the shoulder of said inner tube, said spacer strips defining a relatively larger radial thickness than the thickness of said annular body.
