Abstract

A coaxial cable connector comprises a head and a hollow cylinder. The hollow cylinder comprises a protective cylinder, a tubular shaft, and an elastic cylinder. The tubular shaft comprises a guide hole, a plurality of ladders, a locking flange, and a plurality of hooks. The elastic cylinder comprises a trench and a hook at one end and a locking ring defined by a notch near the other end. A bended metal tube having a stopper is mounted on the protective cylinder. In the coupling process, the coaxial cable inserts into the hollow cylinder. By using a pressure from a tool to break the notch of the elastic cylinder, the locking ring is separable from the elastic ring, and the locking ring shifts forward continuously along an inclined surface of the notch. Since the protective cylinder restrains the locking ring, the connector can couple with the coaxial cable tightly by pressing down the locking ring.

Claims

1. A coaxial cable connector comprising:

a head; and

a hollow cylinder comprising;

a tubular shaft having a guide hole on a center;

an elastic cylinder having a trench and a hook at one end and a locking ring defined by a notch near the other end; and

a protective cylinder having a bent metal tube at one end, wherein the coaxial cable connector is configured to be coupled with a coaxial cable by the steps of;

inserting the coaxial cable into the hollow cylinder;

aligning a front end of an insulating layer mounted on the coaxial cable with a front end of the tubular shaft;

using a tool for breaking the notch of the elastic cylinder and separating the locking ring from the elastic ring;

shifting the locking ring forward continuously along a top surface of the notch, after shifting, the locking ring continuously applies pressure against the elastic cylinder through a restraining force exterted by the protective cylinder against the locking ring in order to tightly couple the coaxial cable with the coaxial cable connector.

2. The coaxial cable connector of claim 1, wherein the coaxial cable connector is a F type connector, a BNC connector, a RCA connector, or an IEC connector.
