Abstract

A coaxial cable connector includes a connection head and a sleeve assembly coupled to the connection head. The sleeve assembly includes a tube, a sleeve, and a metal collar. The sleeve assembly receives a coaxial cable to insert therein from a rear end thereof in such a way that an insulator layer of a front end of the coaxial cable is set substantially flush with a front end of the tube and the sleeve assembly is then acted upon by a force applied by a tool to drive the metal collar frontward against the contact section of the sleeve for breaking and separating the retention section of the sleeve from the sleeve to further move frontward along a surface of the buffering section of the sleeve. Due to a constraint imposed by the metal collar, the buffering section is compressed downward to enhance tightness of engagement between the coaxial cable and the connector.

Claims

1. A coaxial cable connector, comprising:

a connection head; and

a sleeve assembly, which has an end coupled to the connection head, the sleeve assembly comprising a tube, a sleeve, and a metal collar, the tube being received in the sleeve, an end of the sleeve forming in sequence a retention section, a buffering section, and an accommodation section, the retention section and the buffering section having a connection portion therebetween forming a contact section, the metal collar being fit in the retention section with an end of the metal collar positioned against the contact section, wherein the sleeve assembly is adapted to receive a coaxial cable to insert therein from a rear end thereof in such a way that an insulator layer of a front end of the coaxial cable is set substantially flush with a front end of the tube and the sleeve assembly is adapted to be acted upon by a force applied by a tool to drive the metal collar frontward against the contact section for breaking and separating the retention section from the sleeve to further move frontward along a surface of the buffering section, and wherein due to a constraint imposed by the metal collar, the buffering section is compressed downward to thereby enhance tightness of engagement between the coaxial cable and the connector.

2. The coaxial cable connector as claimed in claim 1, wherein the connection head is selected from a group consisting of an F type connection head, a BNC type connection head, an RCA type connection head, and an IEC type connection head.

3. The coaxial cable connector as claimed in claim 1, wherein the connection head forms a first groove and the sleeve has an end forming a second groove to correspond to and mate the second groove for forming a compartment that receives and retains a seal ring therein.

4. The coaxial cable connector as claimed in claim 1, wherein the buffering section comprises a guide slope and the buffering section is formed between the accommodation section and the retention section.

5. The coaxial cable connector as claimed in claim 1, wherein the accommodation section comprises a recess.
