[0020] See also Figures 1 to 4 As shown, the preferred embodiment of the utility model discloses an FPC connector 100, which is mainly used in the connection and installation scene of FPC, and is convenient for repeated hot plugging of FPC. The FPC connector 100 includes an insulating body 10 extending in the lateral direction, a plurality of conductive terminals 20 retained in the insulating body 10, an elastic member 30 located in the insulating body 10, and an FPC board 40 plugged into the insulating body 10. The FPC board 40 is provided with a docking portion 41 plugged into the insulating body 10 and a clamping portion 42 located on both lateral sides of the docking portion 41.

[0021] See also Figure 2 and Figure 3As shown, the insulating body 10 is provided with a proximal portion 11 connected to the docking portion 41 of the FPC board 40, a distal portion 12 longitudinally away from the FPC board 40, and a side portion 13 connecting the proximal portion 11 and the distal portion 12, and the side portion 13 is located on both sides of the proximal portion 11 in the transverse direction. The proximal portion 11 is provided with a receiving groove 110 that is recessed inwardly in the longitudinal direction, and the receiving groove 110 is provided with an insertion interface (not shown) that penetrates the longitudinal end surface of the proximal portion 11, and the docking portion 41 of the FPC board 40 is plugged into the receiving groove 110 through the insertion interface. The side portion 13 is provided with an inwardly recessed groove 131, and the groove 131 is arranged adjacent to the insertion interface and is connected to the receiving groove 110. When the docking portion 41 of the FPC board 40 is plugged into the receiving groove 110, the engaging portion 42 is at least partially exposed to the groove 131.

[0022] Combination Figure 4 As shown, the conductive terminal 20 is provided with a fixed portion fixed in the insulating body 10, a contact portion extending from the fixed portion into the receiving groove 110, and a solder foot extending from the fixed portion out of the insulating body 10, the contact portion is used to contact the gold finger on the docking portion 41, and the solder foot is used to be soldered on a circuit board. In this embodiment, the conductive terminal 20 includes a first terminal 21 and a second terminal 22 spaced apart in the transverse direction, and the contact portions of the first terminal 21 and the second terminal 22 are located at the same height to contact the gold finger on the docking portion 41 together. The first terminal 21 is inserted into the insulating body 10 from the proximal end 11 along the longitudinal direction, and the second terminal 22 is inserted into the insulating body 10 from the distal end 12 along the longitudinal direction, and the first terminal 21 and the second terminal 22 are inserted in opposite directions in the longitudinal direction.

[0023] The elastic member 30 is inserted into the insulating body 10 from the distal end 12 in the longitudinal direction and is provided with a retaining portion 31 retained in the side portion 13, an elastic arm 32 extending from the retaining portion 31 into the groove 131, a guide portion 33 extending from the end of the elastic arm 32 in a reverse bending direction, and a stopper 34 located at the free end of the guide portion 33. The retaining portion 31 is disposed adjacent to the distal end 12, the elastic arm 32 is disposed adjacent to the insertion port, and the free end of the elastic arm 32 is closer to the proximal end 11 in the longitudinal direction than the contact portion of the second terminal 22.

[0024] Specifically, the elastic arm 32 is formed to extend from the holding portion 31 along the longitudinal direction toward the proximal end portion 11, the guide portion 33 is obliquely extended from the end of the elastic arm 32 into the receiving groove 110 to guide the insertion of the docking portion 41, and the stop portion 34 is formed to extend outwardly from the free end of the guide portion 33 along the transverse direction. When the docking portion 41 of the FPC board 40 is inserted into the receiving groove 110, the docking portion 41 pushes the guide portion 33 and drives the elastic arm 32 to deform to avoid the docking portion 41; when the docking portion 41 is fully inserted into the receiving groove 110, the elastic arm 32 rebounds and the guide portion 33 is accommodated in the locking portion 42 to limit the docking portion 41 in the receiving groove 110. At this time, the stop portion 34 is against the rear end surface of the docking portion 41 adjacent to the locking portion 42 to prevent the docking portion 41 from escaping from the receiving groove 110 along the longitudinal direction.

[0025] The elastic member 30 has a free state when the elastic arm 32 is not pressed and a pressed state when the elastic arm 32 is pressed. When the elastic member 30 is in the free state, the FPC board 40 is pulled out, and the docking portion 41 pushes the stopper 34 outwardly, and the stopper 34 drives the free end of the elastic arm 32 to deform in the lateral direction through the guide portion 33. At this time, the stopper 34 always maintains contact with the docking portion 41, and the docking portion 41 cannot be pulled out from the receiving groove 110. When the elastic member 30 is in the pressed state, the elastic arm 32 is pressed and cannot be deformed; when the FPC board 40 is pulled out, the docking portion 41 pushes the stopper 34 outwardly, and then drives the guide portion 33 to deform in the lateral direction, so as to drive the stopper 34 to disengage from the engaging portion 42 in the lateral direction, and at this time, the docking portion 41 can be pulled out of the receiving groove 110 without obstacles.

[0026] The groove 131 penetrates upwardly through the top surface of the insulating body 10 so that the elastic arm 32 , the guide portion 33 and the stopper 34 of the elastic member 30 are exposed from the insulating body 10 , so as to better observe and operate the connection process between the elastic member 30 and the FPC board 40 .

[0027] In the present invention, the FPC connector 100 includes an elastic member 30 located in the insulating body 10, and the elastic member 30 is provided with a holding portion 31 held in the side portion 13, an elastic arm 32 extending from the holding portion 31 into the groove 131, and a guide portion 33 extending from the end of the elastic arm 32 by reverse bending; when the docking portion 41 of the FPC board 40 is inserted into the receiving groove 110, the docking portion 41 pushes the guide portion 33 and drives the elastic arm 32 to deform to avoid the docking portion 41, and when the docking portion 41 is fully inserted into the receiving groove 110, the elastic arm 32 rebounds and the guide portion 33 is accommodated in the locking portion 42 to limit the docking portion 41 in the receiving groove 110, thereby realizing the automatic locking of the FPC connector 100 and greatly simplifying the plug-in process of the FPC board.

[0028] In summary, the above are only preferred embodiments of the present invention, and should not be used to limit the scope of the present invention. That is, all simple equivalent changes and modifications made according to the claims and description of the present invention should still fall within the scope of the present invention.
