Positioning of contacts in audio jack

摘要

An electronic device may include an audio jack allowing a peripheral audio output device to be connected to the electronic device by inserting the plug into the jack. The jack may include a receptacle that extends into the housing. A plurality of contacts may be included in the receptacle, arranged along a longitudinal direction of the receptacle. A latch may be installed in the receptacle, at an intermediate location between the proximal end and the distal end of the receptacle, to secure a position of the plug in the receptacle. A detect contact may be positioned at the distal end of the receptacle, separate from the latch. The detect contact may be actuated by the distal end of the tip of the plug to indicate that the plug is fully inserted in the receptacle. Upon actuation of the detect contact, the device may transfer audio output functionality to the peripheral device connected to the device by the plug inserted in the jack.

主权项

1. A device, comprising:
a housing; a receptacle extending into the housing and configured to removably receive a plug therein; a latch included in the receptacle and configured to engage the plug so as to secure the plug in a predetermined position of in the receptacle when the latch is engaged by the plug; a plurality of contacts included in the receptacle, the plurality of contacts including:
a detect contact at a distal end of the receptacle, the detect contact configured to be actuated by contact with a distal end of the plug, the detect contact being configured to generate a signal indicating full insertion of the plug in the receptacle when actuated by the distal end of the plug; anda switch contact configured to selectively contact the detect contact in response to the distal end of the plug being located in a predetermined position in the receptacle; and a controller configured for controlling operation of the device and configured for receiving the generated signal, wherein, in an actuated state of the detect contact, a contact portion of the switch contact directly contacts a contact portion of the detect contact in response to a force applied to the switch contact by the distal end of the plug.
