Abstract: An auxiliary test apparatus for electromagnetic compatibility includes two substantially parallel side plates and a dividing plate substantially perpendicularly connected between centerlines of the side plates. A through hole is defined in a center portion of the dividing plate. Top and bottom surfaces of the dividing plate and the inner surfaces of the side plates are covered by conductive foam.

Abstract: A radio frequency(RF) printed circuit board (PCB) includes an RF circuit for generating high frequency signals. The RF PCB is connected to an EMC measuring device when measuring the EMC thereof. The measuring device includes a probe pin and a shielding barrel surrounding the probe pin. The shielding barrel includes an end surface at a distal end thereof. The RF PCB further includes a test node connected to the RF circuit and a ground node surrounding the test node. The test node contacts the probe pin and outputs the high frequency signals when measuring the EMC of the RF PCB. The ground node corresponds to the end surface and contacts the end surface while the probe pin contacts the test node.

Abstract: An audio connector includes an audio plug and a jack. The audio connector includes an isolating housing and a terminal partially positioned in the housing. The jack forms a receiving portion for receiving the terminal. The terminal includes a metallic flange extending out of the housing. The housing forms an isolated covering portion on the main body surrounding the metallic flange.
