FPCB connecting device {CONNECTING APPARATUS FOR FLEXIBLE PRINTED CIRCUIT BOARD}

The present invention relates to an FPCB connection device, and more particularly, to an FPCB connection device for directly connecting each terminal of two FPCBs to each other.

In general, FPCB (Flexible Printed Circuit Board) is an electronic component developed with miniaturization and light weight of electronic products. It is excellent in workability, has high heat resistance, durability, chemical resistance, and heat resistance, so it is a key component of all electronic products. It is widely used in computer peripherals, mobile phones, DVD, TFT, LCD, satellite equipment, military equipment, and medical equipment.

FPCB has the advantage of easy wiring in complex and narrow spaces because it is thin and flexible with several circuits on the insulator board to carry several signals.

However, in order to connect two FPCBs due to the large number of contacts, a separate connection method for transmitting and receiving signals is required.

As a method of connecting the FPCBs of two devices, there is a lead method for permanently connecting the contacts of each FPCB and a pin coupling method for temporarily connecting the contacts.

Soldering methods, however, have limitations in confined spaces or working areas where thermal heating is not possible, and the hassle of working on multiple contacts one by one.

In addition, the pin coupling method has the advantage that it can be easily worked when connecting between FPCBs, but it is necessary to attach parts necessary for pin connection to both or one FPCBs in advance, and a separate locking device is required to maintain contact connection due to external vibration or shock. .

And these connection methods require an additional cover to protect the device after the connection is completed.

As a prior art document related to the present invention, Korean Patent No. 1459480 has been proposed 'a connection unit of a flexible printed circuit board and a connection method thereof'.

However, Korean Patent No. 1459480, 'Connecting Unit of Flexible Printed Circuit Board and Connecting Method thereof', connects the first flexible printed circuit board and the second flexible printed circuit board by pressing the terminal by soldering through a through hole. Is semi-permanently connected through soldering, and thus it is virtually impossible to separate the first flexible printed circuit board and the second flexible printed circuit board again, and when an abnormality occurs in the connection part, it is difficult to check and repair the same.
