Electronic device
According to one embodiment, an electronic device includes a housing including a wall portion, a printed circuit board including a plurality of lines and provided in the housing, and a connector formed of a part of the housing and a part of the printed circuit board. The connector includes an engagement hole formed in the wall portion and into which a connector plug is inserted. The connector further includes a shell formed of a portion located around the engagement hole in the wall portion, a tongue portion formed of a part of the printed circuit board and provided in the engagement hole, and connection terminals formed of the lines extending to and on a surface of the tongue portion.
1. An electronic device comprising: a housing comprising a wall portion formed with an engagement hole; a printed circuit board including a first top flat surface, a second bottom flat surface, and a wiring pattern comprising a plurality of lines and provided in the housing; a tongue portion formed of a part of the printed circuit board and flush with the first top flat surface and the second bottom flat surface, and provided in the engagement hole; and a connector formed of the engagement hole and the tongue portion in the engagement hole, and into which a connecter plug is to be inserted, wherein some parts of the lines of the printed circuit board extend on a surface of the tongue portion and constitute connection terminals of the connector; a ground layer is formed in the printed circuit board and exposed to side surfaces and a distal end surface of the tongue portion and the tongue portion comprises a through-hole formed in each of the side surfaces to constitute an engagement recess configured to engage and ground with the connector plug, and the grand layer is exposed to the engagement recess to be connectable to a ground terminal of the connector plug.
2. The electronic device of claim 1 , wherein
the tongue portion comprises a first surface and a second surface opposing the first surface, and
the connection terminals comprise:
a plurality of first connection terminals formed of the lines extending on the first surface of the tongue portion; and
a plurality of second connection terminals formed of the lines extending on the second surface of the tongue portion.
3. The electronic device of claim 2 , wherein
the first connection terminals and the second connection terminals are symmetrically provided.
4. The electronic device of claim 3 , wherein
the tongue portion is located in the engagement hole such that a certain space is defined around the tongue portion.
5. The electronic device of claim 4 , wherein
the printed circuit board comprises a side edge facing an internal surface of the wall portion, and
the tongue portion projects from the side edge into the engagement hole.
