Abstract

Provided is a flexible printed circuit board (FPCB) including a circuit connector connected to a circuit board connector of a printed circuit board (PCB) for electronic equipment. A first compression unit and a second compression unit are included in the circuit connector, and a folding unit is provided at an interface between the first compression unit and the second compression unit such that the folding unit, instead of a plating interface of the first compression unit and the second compression unit, is folded by a force generated when the circuit connector is connected to the circuit board connector.

Claims

1. A flexible printed circuit board (FPCB) having a circuit connector for connecting to a circuit board connector of a printed circuit board (PCB) for electronic equipment, the circuit connector comprising:

a first compression unit disposed on the FPCB adjacent to a second compression unit; and

a folding unit provided at an interface between the first compression unit and the second compression unit such that the folding unit is folded by a force generated when the circuit connector is connected to the circuit board connector.

2. The FPCB of claim 1, wherein the folding unit provides a folding depression to flexible folding when the circuit connector is connected to the circuit board connector, and the shape of the folding depression is bent and provided in the shape of a step.

3. The FPCB of claim 1, wherein the first compression unit comprises a plurality of protrusion units for bending the shape of the folding depression.

4. The FPCB of claim 1, wherein the second compression unit comprises a plurality of insertion units into which the protrusion units are inserted for bending the shape of the folding depression.

5. The FPCB of claim 3, wherein the second compression unit comprises a plurality of insertion units into which the protrusion units are inserted for bending the shape of the folding depression.

6. The FPCB of claim 1, wherein the folding depression is in a zigzag shape such that one side is protruded and the other side is depressed.

7. The FPCB of claim 1, wherein the zigzag shape of the folding depression comprises at least one of straight lines and curves.

8. A flexible printed circuit board (FPCB) comprising a circuit connector connected to a circuit board connector of a printed circuit board (PCB) for electronic equipment,

wherein the circuit connector comprises at least one compression units, and a folding unit is provided at an interface between the compression units such that the folding unit is folded by a force generated when the circuit connector is connected to the circuit board connector.
