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.
A connector system for coupling to an audio jack of an audio player. The system includes an audio plug having a first portion configured to fit into the audio jack, the plug including at least one conductor forming a conducting path with the jack; and, a second portion configured to remain on the outside of the jack of the audio player after the first portion is inserted into the jack, the second portion having at least one contact coupled to the at least one conductor. The jack also includes a protruding edge surrounding the at least one contact. The system further includes a coupler to the plug having a first end having at least one coupling contact disposed thereon to contact the at least one contact on the plug, and a cap surrounding the at least one coupling contact, the cap configured to releasably engage the protruding edge on the plug; and, a receptacle at a second end of the coupler for receiving a standard plug.
An electric signal transmission connector assembly includes at least one plug and a receptacle mounted to an electronic apparatus. The plug and the receptacle are internally provided at two opposite positions with a permanent magnet each, so that the plug may be easily connected to the receptacle through magnetic attraction between the two magnets. The plug and the receptacle also include a plurality of terminals each. When the plug and the receptacle are magnetically connected to each other, the terminals thereof are contacted with one another to enable transmission of electric signals or supply of power via the plug and the receptacle. Two or more plugs may be stacked up to magnetically connect to the same one receptacle to save a lot of space by magnetically connecting a lower connecting section of an upper plug to an upper receiving section of a lower plug.
