Abstract

Capacitive coupled connector 1 for mounting to a conductive panel comprises an insulative dielectric skirt section 25, a conductive shell 2 within the insulative body 25 and having cylindrical wall 6 with coupling portion for coupling the shell to the panel, an insulative dielectric liner section 26 within the conductive shell 2, a conductive contact 4 extending within the liner section 26, electrical capacitor elements 46 and 47 inset within the outer profile of the connector 1, and conductive clip 5 retaining the capacitor elements 46 and 47 in pressure contact with the shell 2, contact surfaces of the clip establishing a capacitive electrical coupling of the shell 2 and the panel. the insulative outer skirt section 25 and the insulative dielectric liner section 26 form a complex insulative body 3 having interconnecting sections 27 and 28 through apertures 23 and 24 in the cylindrical wall 6 of the conductive shell 2. The clip 5 is an annular disc 48 residing on a skirt portion 25 of the insulative body and has helical arms 49, 50, 51, and 52 circumferential to the disc 47 to establish conductive paths to the panel, and clip fingers retaining the capacitor elements 46 and 47 in pressure contact with the shell 2.

Claims

1. Capacitive coupled electrical connector for mounting to a conductive panel, comprising:

an insulative outer skirt section, a conductive shell within the insulative skirt section and having a cylindrical wall, an insulative liner section within the conductor shell, a conductive contact extending within the liner section, electrical capacitor elements inset within the outer profile of the connector, a conductive clip retaining the capacitor elements in pressure contact with the shell, contact surfaces of the clip establishing a capacitive electrical coupling of the shell and the panel wherein;

the coupling shell has apertures through its cylindrical wall, and the insulative outer skirt section and the insulative liner section form a unitary complex insulative body having interconnecting sections through the apertures on the cylindrical wall, and wherein;

the conductive clip is an annular disc residing on the skirt section of the unitary complex insulative body and encircling the conductive shell.

2. The electrical connector of claim 1, wherein the clip is an annular disc having helical arms circumferential to the disc and with clip fingers retaining the capacitor elements in pressure contact with said shell.

3. The electrical connector of claim 2, wherein the clip fingers are folded back to provide added resiliency to retain the capacitor elements in pressure contact with said shell.

4. The electrical connector of claim 2, wherein each helical arm terminates with a hertz dot to provide single point contact for a conductive path to the conductive panel.
