  • the electronic apparatus includes an audio jack 30 for insertion of a plug.
  • the audio jack includes a hollow insulated housing having an opening, an accommodation space being formed within the insulated housing for accommodating the plug inserted from the opening, and a plurality of elastic terminals being arranged on the insulated housing.
  • the insulated housing includes a fixed portion and a rotating portion rotating relative to the fixed portion and on which at least two elastic terminals are arranged; the at least two elastic terminals of the rotating portion being in contact with different pins of a printed circuit board 50 of the audio jack 30 respectively when the rotating portion is in a first position and rotates relative to the fixed portion to a second position.
  • the rotating portion and the fixed portion are connected in a nested manner.
  • a first elastic terminal and second elastic terminal are arranged on the rotating portion and having respectively a first extending portion, a second extending portion and a body portion arranged between the first extending portion and the second extending portion.
  • the first extending portion of the first elastic terminal is in contact with a first pin of the printed circuit board of the audio jack, and the first extending portion of the second elastic terminal is in contact with a second pin of the printed circuit board of the audio jack.
  • the rotating portion rotates relative to the fixed portion to the second position, the second extending portion of the second elastic terminal is in contact with the first pin of the printed circuit board of the audio jack, and the second extending portion of the first elastic terminal is in contact with the second pin of the printed circuit board of the audio jack.
  • the first pin is a GND contact pad
  • the second pin is an MIC contact pad
  • the first pin is an MIC contact pad
  • the second pin is a GND contact pad
  • the body portion of the first elastic terminal is arranged at a first side of the rotating portion; the first extending portion of the first elastic terminal is arranged at a second side of the rotating portion perpendicular to the first side, close to the opening and exposed from the rotating portion; the second extending portion of the first elastic terminal is arranged at a third side of the rotating portion perpendicular to the first side, close to the fixed portion and exposed from the rotating portion; wherein the projections of the first extending portion of the first elastic terminal and the second extending portion of the first elastic terminal on the plane of the second side or the third side of the rotating portion are spaced apart at a certain distance.
  • the body portion of the second elastic terminal is arranged at a fourth side of the rotating portion in parallel with the first side; the first extending portion of the second elastic terminal is arranged at the second side of the rotating portion perpendicular to the first side, close to the fixed portion and exposed from the rotating portion; the second extending portion of the second elastic terminal is arranged at the third side of the rotating portion perpendicular to the first side, close to the opening and exposed from the rotating portion; wherein the projections of the first extending portion of the second elastic terminal and the second extending portion of the second elastic terminal on the plane of the second side or the third side of the rotating portion are spaced apart at a certain distance.
  • the projections of the first extending portion of the first elastic terminal and the second extending portion of the second elastic terminal on the plane of the second side or the third side of the rotating portion are overlapped; and the projections of the second extending portion of the first elastic terminal and the first extending portion of the second elastic terminal on the plane of the second side or the third side of the rotating portion are overlapped.
