Compact AC noise filter with ground inductor
First Claim
1. A compact AC noise filter comprising:
- a plug connector assembly of electrically insulating material including a support wall from which forwardly extends an electrically conductive ground terminal and two electrically conductive power supply terminals and an electrically conductive ground tab connected to the ground terminal, extending rearwardly from said support wall;
a filter assembly housing of electrically insulating material attached to said plug connector assembly, said filter assembly housing having a recess, and a cavity which is physically and electrically isolated from said recess;
an electrically conductive shielding member located on said plug connector assembly and said filter assembly housing;
means within said filter assembly housing to electronically filter noise of an inputted AC signal, including at least one capacitor, and first and second inductors;
said first inductor mounted in said filter assembly housing within said recess, and said second inductor mounted in said cavity and including a coil having ends respectively electrically connected to said ground tab and said shielding member.

Abstract
A compact AC filter having a plug connection assembly including a support wall from which extends in a forward direction a ground terminal and a pair of power terminals and in a rearward direction a ground tab connected to the ground terminal. A filter assembly housing having a recess and a cavity is attached to the plug connector assembly and contains filter components including at least one capacitor, an inductor in said recess and an earth (ground) inducter in said cavity. A shield member bridges the connector assembly and filter assembly housing and the ground tab extends into the filter housing. The ends of the earth inducter coil are respectively connected to the shield member and the ground tab.
