The present invention relates to a flexible cable connector, and more particularly, to a flexible cable connector capable of firmly reinforcing the bonding state with a printed circuit board (PCB) and improving the grounding performance.

In general, the flexible cable is a relatively thin film type cable that is divided into FFC type (Flexible Flat Cable) and FPC type (Flexible Printed Circuit).

In addition, in order to electrically connect the flexible cable to the printed circuit board, the flexible cable connector is mounted on the printed circuit board.

Hereinafter, one example of such a flexible cable connector will be briefly described with reference to FIG. 1.

As shown, a housing 10 fixed on a printed circuit board and formed of a synthetic resin material, a plurality of terminals 20 inserted into and fixed to the housing 10 at the rear of the housing 10, and the housing 10. Actuator 30 for fixing the flexible cable inserted into the front of the housing 10, and a fitting nail 40 for raising the actuator 30 to insert into the pivot groove 20a of the terminal 20 Is done.

In this case, a seating slot 11 in which the FPC / FFC is seated and fixed is formed at the front end of the housing 10, and a terminal insertion part 12 in which the terminal 20 is inserted and fixed in the rear end of the housing 10 is formed. Fixed arms 13 are formed at both sides of the housing 10, and fixing grooves 13a are formed at both ends of the actuator 30 inside the fixed arms 13.

In addition, the fixing protrusions 31 rotatably fixed to the fixing grooves 13a protrude from both rear ends of the actuator 30, and the actuators 30 are positioned at both ends of the front end of the actuator 30. The locking protrusion 32 is formed to protrude from both sides of the front portion of the housing 10 so as to lock the actuator 30 so as not to rotate.

On the other hand, the rear end of the actuator 30 is formed with a rotating shaft 33 is inserted into the pivot groove 20a of the terminal 20 to form the center of rotation of the actuator 30.

The above-mentioned flexible cable connector inserts the rear end portion between the fixed arms 13 while the actuator 30 is placed vertically so that the fixing protrusions 31 are inserted into the fixing grooves 13a of the housing 10, respectively. Next, a plurality of terminals 20 are respectively inserted into the terminal insertion part 12, and the fitting nails 40 are respectively inserted into both sides of the housing 10 to insert the rotary shaft 33 of the actuator 30 into the terminal 20. The assembly is completed by inserting into the pivot groove 20a.

However, the conventional flexible cable connector configured as described above is provided with a grounding terminal for grounding, and the grounding terminal is soldered and fixed to the printed circuit board. When the end of the flexible cable is connected to the housing, There is a problem that the ground is not made correctly due to damage or deformation.

In addition, since the conventional flexible cable connector has an assembly structure mounted on a printed circuit board by soldering, the assembly strength between the connector and the printed circuit board is very low, and may be damaged by surrounding vibration or external force. In order to avoid this, when adding a separate structure on the printed circuit board there was a disadvantage that the assembly structure and the assembly work itself is complicated.

In addition, the conventional flexible cable connector is configured to be locked only by the locking protrusion protruding on both sides of the front end portion of the actuator while the actuator is placed in the closed position, so that the front end of the actuator has a weak fixing force and the FPC / FFC is connected to the terminal. If you pull up the part a little or give a shock to the housing, the locking state of the actuator may be easily released. In the end, the fixing force to fix the flexible cable may be weakened and the connection force may be weakened or released completely.

The present invention has been made to solve the above problems of the prior art, by mounting a ground cover in the seating slot of the housing, it is possible to enhance the grounding performance and to increase the assembly strength when mounted on the printed circuit board, It is an object of the present invention to provide a flexible cable connector which can prevent the detachment of the flexible cable so that the performance can be improved.
