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 connector includes a connector receptacle and a cable. The connector receptacle includes an insulating body, a metallic box and a magnetic ring. The metallic box is connected to the insulating body and defines a closed receiving cavity. The cable includes a cable head. The cable head is received in the receiving cavity, and extends through the magnetic ring.

Abstract: A portable electronic device includes a housing portion, a number of light emitted diodes (LEDs) received in the housing portion, and an anti-static structure. The housing portion defines a plurality of through holes. The anti-static structure is positioned between the housing portion and the LEDs, and defines a plurality of recesses corresponding to the through holes. The anti-static structure is made from anti-static and transparent material; the LEDs are separated from the housing portion by the anti-static structure. Each LED is received within the corresponding recess, static charges on the housing portion are discharged to ground, and the light emitted from the LEDs is emitted out of the portable electronic device along the recesses, the anti-static structure, and through the through holes for user observation.
