Patent ID: 8147259

Claim:
A fixing device of an anti-theft signal connector, the fixing device being disposed in the anti-theft signal connector, the fixing device being electrically connected with a resistance and a capacitor, one end of the resistance being electrically connected with one end of the capacitor, another end of the resistance having a first conductive wire which is axially extended outward, another end of the capacitor having a second conductive wire which is axially extended outward, the first conductive wire being electrically connected with the fixing device, the fixing device comprising: a connection seat disposed in the anti-theft signal connector, the connection seat being an axial metallic pipe, the connection seat comprising a positioning plate which is located in a rear section of the connection seat and integrally formed with the connection seat, an inner side of the positioning plate having a central conical hole, an outer side of the positioning plate having a central protrusion, the protrusion having a round hole which communicates with the conical hole and has a diameter smaller than that of the conical hole; a container made of an insulation material and axially disposed in a front section of the connection seat, the container having a receiving trough therein facing the positioning plate, the receiving trough of the container having a bottom formed with a central through hole, the resistance and the capacitor being received in the receiving trough, the first conductive wire being extended out of the round hole and welded to the protrusion, the second conductive wire being extended out of the through hole; and a positioning plug disposed in the front section of the connection seat, the container being positioned between the positioning plate and the positioning plug, the second conductive wire inserting through the positioning plug; thereby, the positioning plate being integrally formed with the connection seat for the resistance and the capacitor received in the container to be steady fixed between the connection seat and the positioning plug, the resistance and the capacitor and the connection seat generating stable impedance match, without signal loss under static electricity.
