1. A plug detect apparatus for detecting the presence of a plug, wherein the plug has at least a first plug contact, the plug detect apparatus comprising:
- a receptacle configured to accept the plug;
a first receptacle contact disposed in the receptacle, wherein the first receptacle contact is configured to communicate with the first plug contact;
a detect contact disposed in the receptacle relative to the first receptacle contact so that the presence of the plug within the receptacle creates a signal path through the plug and between the detect contact and the first receptacle contact, wherein the detect contact and the first receptacle contact both contact the same first plug contact when the plug is present in the receptacle; and
detection circuitry coupled to the detect contact and the first receptacle contact to detect that the signal path is a low or a high impedance path.

Abstract
Plug detection mechanisms can be provided for detecting when a plug of an accessory component is present within a jack of an electronic device. A detect contact and a jack contact may be positioned within a receptacle of the jack such that a signal path may be created through the plug and between the detect contact and the jack contact when the plug is present within the receptacle of the jack. The detect contact may be biased to exert a retention force on the plug. The detect contact may be positioned to contact the plug within an indent of the plug.

12. An electronic device capable of detecting the presence of a plug of an accessory component, wherein the plug includes a first plug contact, the electronic device comprising:
-
a receptacle configured to accept the plug; a first receptacle contact disposed in the receptacle, wherein the first receptacle contact is configured to communicate with the first plug contact; a detect contact disposed in the receptacle relative to the first receptacle contact so that the presence of the plug within the receptacle creates a plug signal path through the plug and between the detect contact and the first receptacle contact, wherein the detect contact and the first receptacle contact both contact the same first plug contact when the plug is present in the receptacle; and detection circuitry coupled to the detect contact and the first receptacle contact to detect that the signal path is a low or a high impedance path. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 22, 25, 26, 27, 29)
