Abstract
Disclosed are a flexible printed circuit board and a mobile terminal using the same. The mobile terminal includes a printed circuit board (PCB), and a flexible printed circuit board (FPCB) connected to the printed circuit board. The flexible printed circuit board includes a branch extending from one side of the flexible printed circuit board, at least one switch provided on the branch and acquiring a key input signal, and a connector provided on an end portion of the branch and coupled to the flexible printed circuit board.
Claims19
A mobile terminal, comprising:
- a printed circuit board (PCB);
- and
- a flexible printed circuit board (FPCB) coupled to the PCB, the FPCB comprising:
- a main portion;
- a branch portion extending from a first side of the main portion, the branch portion comprising a first end located at a distal end of the branch portion from the main portion;
- at least one switch positioned on the branch portion, the at least one switch configured for receiving a key input signal;
- and
- a connector coupled to the first end of the branch portion and configured for coupling the FPCB to the PCB.
A mobile terminal, comprising:
- a printed circuit board (PCB);
- and
- a flexible printed circuit board (FPCB) coupled to the PCB, the FPCB comprising:
- a main portion;
- a branch portion extending from a first side of the main portion;
- a signal line path positioned on the branch portion, the signal line path comprising a plurality of signal lines, each of the plurality of signal lines configured for conducting signals between the FPCB and the PCB, the plurality of signal lines including at least one lead wire;
- at least one switch positioned on the signal line path, the at least one switch configured for receiving a key input signal;
- and
- a connector coupled to the branch portion and configured for coupling the plurality of signal lines to the PCB,
- wherein each lead wire of the at least one lead wire corresponds to a switch of the at least one switch and is configured for conducting the signals intermittently based on the received key input signal of the corresponding switch.
A flexible printed circuit board (FPCB), comprising:
- a main portion;
- an electronic component mounted on the main portion;
- a branch portion extending from a first side of the main portion, the branch portion comprising a first end located at a distal end of the branch portion away from the main portion;
- at least one switch positioned on the branch portion, the at least one switch configured for receiving a key input signal;
- and
- a connector coupled to the first end of the branch portion and configured for coupling the FPCB to another circuit board.
