Audio jack with EMI shielding

摘要

An audio jack for an audio plug for use in an electrical device, comprising a non-conductive enclosure having a front side and defining a cavity having an aperture within the front side for receiving the audio plug, the aperture having a first diameter, the cavity extending along a longitudinal axis; a conductive shielding formed from sheet metal folded over at least five sides of the enclosure including the front side, the shielding defining a shielding aperture centered on the enclosure aperture and having a second diameter larger than the first diameter; and a ground contact connected to the conductive shielding.

主权项

1. A jack for a plug, the jack comprising:
a non-conductive enclosure defining a cavity into which may be received the plug via an enclosure aperture in a front side of the non-conductive enclosure; a conductive shielding folded over at least five sides of the non-conductive enclosure including the front side, the shielding defining a shielding aperture centered on the enclosure aperture; and a grounding spring contact connected to the conductive shielding, the grounding spring contact having a grounding spring contact portion external to the non-conductive enclosure, the grounding spring contact portion biased to contact a grounding plane on a printed circuit board.
