Abstract

A RF communication system includes a speaker microphone connector connecting a communication station with a communication unit to transmit an audio signal and RF signal therebetween. The speaker microphone connector includes an audio cable, a RF cable and a tubular enclosing shelter enclosing the audio cable and the RF cable therein, wherein an end portion of the RF cable extends out of the enclosing shelter between first and second ends thereof such that the end portion of the RF cable is split with the audio cable to individually connect to the communication station. In addition, a retaining device is provided at the enclosing shelter to retain the RF cable and the audio cable in a splitting manner.

11. The RF communicator, as recited in claim 2, wherein said retaining means further comprises two securing rings securely attaching to said enclosing shelter at two slit ends of said splitting slit respectively so as to securely hold said RF cable and said audio cable in position along said splitting slit.

12. The RF communicator, as recited in claim 2, wherein a portion of said enclosing shelter is cut along a circumferential thereof to form said splitting slit to allow said end portion of said RF cable extending out of said interior cavity through said splitting slit.

13. The RF communicator, as recited in claim 2, wherein said retaining means further comprises a T-shaped tubular retainer securely mounted at said enclosing shelter at said splitting slit, wherein said tubular retainer has first, second and third openings that said audio cable is extended from said first opening to said second opening within said interior cavity while said end portion of said RF cable is extended from said first opening to said third opening to extend out of said interior cavity of said enclosing shelter.

14. The RF communicator, as recited in claim 1, wherein said retaining means further comprises a sealing shelter which extends from said enclosing shelter to said RF connector and receives said end portion of said RF cable in a concealed manner.

15. A process of manufacturing a speaker microphone connector to communicatively connect a communication unit to a communication station, wherein the process comprises the steps of:

(a) receiving an audio cable and a RF cable along a tubular enclosing shelter, wherein said audio cable is electrically extended from an audio transmitter of said communication unit while said RF cable is operatively extended from a RF transmitter of said communication unit;

(b) forming a splitting slit at said enclosing shelter between first and second ends thereof, wherein said first end of said enclosing shelter is extended from said communication unit;

(c) pulling out an end portion of said RF cable out of an interior cavity of said enclosing shelter through said splitting slit such that said RF cable is split with said audio cable at said splitting slit;
