[0019] The utility model is further described below in conjunction with the accompanying drawings:

[0020] like Figures 1 to 4As shown, a flexible flat cable 13 connector includes a line end connector 1 and a board end connector 2, the line end connector 1 includes a line end housing 11, a line end terminal 12 and a flexible flat cable 13, the line end housing 11 is plugged into the board end connector 2, the line end terminal 12 includes an integrated plug-in portion 121 and a crimping portion 122, the plug-in portion 121 is fixed in the line end housing 11, the front end of the crimping portion 122 is connected to the plug-in portion 121, and the left and right sides of the rear end of the crimping portion 122 are provided with piercing pressing pieces 1221 protruding upward, a plurality of groups of connecting wires 131 are arranged in the left and right directions in the flexible flat cable 13, the top of the piercing pressing piece 1221 is a sharp corner, and the top of the piercing pressing piece 1221 passes through the flexible flat cable 13 and then bends inward and is pressed tightly on the connecting wire 131.

[0021] The connector is divided into a board-end connector 2 fixed on the PCB board and a line-end connector 1 connected to the connecting wire 131. The line-end connector 1 and the board-end connector 2 are plugged together to realize signal connection. A piercing pressing piece 1221 is arranged on the crimping portion 122 of the line-end terminal 12. When the flexible flat cable 13 is connected to the line-end terminal 12, it is only necessary to use a crimping machine to pierce the flexible flat cable 13 with the pointed part of the piercing pressing piece 1221 and then bend it inward to contact with the connecting wire 131 to complete the connection between the flexible flat cable 13 and the line-end terminal 12. There is no need to use welding, which greatly simplifies the assembly process and improves production efficiency. On the other hand, by using the flexible flat cable 13 to replace the traditional wire, more space can be saved.

[0022] The piercing pressing piece 1221 on the left side of the crimping part 122 is staggered with the piercing pressing piece 1221 on the right end of the crimping part 122. The staggered arrangement of the piercing pressing pieces 1221 on the left and right sides provides more sufficient space for bending the piercing pressing pieces 1221 during crimping with the connecting wire 131, thereby avoiding interference between the piercing pressing pieces 1221 on the left and right sides during bending.

[0023] The soft flat cable 13 is an FPC flexible flat cable or an FFC flexible flat cable. The piercing pressing sheet 1221 is applicable to both the FPC flexible flat cable and the FFC flexible flat cable.

[0024] The board-end connector 2 includes a board-end housing 21 and a board-end terminal 22. The board-end terminal 22 is fixed in the board-end housing 21 and the rear end is inserted in the plug-in portion 121. The line-end housing 11 is inserted in the board-end housing 21. When the line-end connector 1 and the board-end connector 2 are plugged and assembled, the front end of the line-end housing 11 on the line-end connector 1 is inserted in the board-end housing 21, and the rear end of the board-end terminal 22 is inserted in the plug-in portion 121 of the line-end terminal 12, thereby completing the assembly and connection.

[0025] The left and right sides of the line terminal housing 11 are provided with buckles 111, and the upper and lower sides of the line terminal housing 11 are provided with pressure plates 112 with tilted front ends. The front ends of the pressure plates 112 tilt outward and touch the inner wall of the board terminal housing 21. The left and right sides of the board terminal housing 21 are provided with card slots 211, and the buckles 111 are buckled into the card slots 211. After the line terminal connector 1 and the board terminal connector 2 are plugged and assembled, the buckles 111 are buckled into the card slots 211 to make the connection firm and reliable. At this time, the front end of the pressure plate 112 touches the inner wall of the board terminal housing 21, and the front end of the pressure plate 112 is compressed toward the middle of the line terminal housing 11. The pressure plate 112 applies pressure to the board terminal housing 21, thereby further fixing the line terminal housing 11, and making the connection between the line terminal terminal 12 and the board terminal 22 more stable.

[0026] The pressure plate 112 is provided with a plurality of guide grooves 1121, and the board end housing 21 is provided with a plurality of guide ribs 212, and the guide ribs 212 correspond to the guide grooves 1121. During the plug-in assembly of the line end connector 1 and the board end connector 2, the rear end of the guide ribs 212 is inserted from the front end of the guide grooves 1121, which plays a role of limiting and guiding the plug-in process, improving the plug-in accuracy and convenience. On the other hand, the guide ribs 212 are also conducive to improving the inner wall strength of the board end housing 21, reducing the deformation of the board end housing 21, and further improving the plug-in accuracy.

[0027] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
