Abstract
The invention provides an audio plug capable of preventing excessive stress from being applied to a plug by enabling a plug body to be detached from a plug-in portion equipped with a channel plug, thus preventing damage and deterioration of function of the plug or a connecting portion between a cable and the plug. An audio plug 1 is equipped with a plug body 2 connected to a cable 3 leading to a headset, and an adapter 20 having channel plugs 30 and 31 that can be plugged into a jack 73, capable of transmitting audio signals from the jack 73 to the plug body 2 when attached. Since the adapter 20 is detachably attached to the plug body 2 by magnetic force, when a force greater than the magnetic force is applied from the cable 3, the plug body 2 is detached from the adapter 20 leaving the adapter 20 plugged into the jack 73, thus preventing poor contact or disconnection caused by excessive force applied to a connecting portion 5 of the cable 3.
