[0024] See also Figure 1 As shown, the technical solution adopted in this specific embodiment is: an FFC wire positioning and bending device, which includes a bending seat 1, a bending plate 2 and a hinge mechanism 3, and all three are made of plastic. Compared with metal materials, the full plastic material is lighter, easier to carry and cheaper. The bending plate 2 is movably installed in the bending seat 1 through the hinge mechanism 3.

[0025] The bending seat 1 is provided with a wire limiting groove 11 along the length direction, and the wire limiting groove 11 divides the bending seat 1 into two parts, the upper and lower parts. The wire limiting groove 11 can ensure that the wire remains stable during the bending process, avoids deviation or sliding, and improves the accuracy and consistency of the bending. The upper part of the bending seat 1 is provided with three through grooves 12 connected to the wire limiting groove 11, and the angles between the three through grooves 12 and the side wall of the bending seat 1 are 90°, 60° and 30° respectively.

[0026] The lower part of the bending seat 1 is provided with three bending placement grooves 13 for placing the bending plate 2, and the three bending placement grooves 13 are connected to the wire limiting groove 11, and the angles between the three bending placement grooves 13 and the side wall of the bending seat 1 are 90°, 60° and 30° respectively. The through groove 12 and the bending placement groove 13 are in the same position and overlap. This design allows the user to choose different bending angles according to needs, increasing the flexibility and adaptability of the device. The outer side of the bending placement groove 13 is provided with a square plug hole 14 that is compatible with the hinge mechanism 3. This design allows the bending plate 2 to be firmly connected to the bending seat 1 through the hinge mechanism 3, ensuring stability and reliability during the bending process.

[0027] The bending plate 2 is placed in the bending placement groove 13 , and the thickness of the bending plate 2 is the same as the depth of the bending placement groove 13 .

[0028] The hinge mechanism 3 includes a rotating shaft 31 and a plug-in column 32. The entire hinge mechanism 3 can realize rotation and plug-in operations. In this way, the user can easily adjust the position of the bending plate 2 to adapt to different folding angles, thereby improving the flexibility and adaptability of the device. The rotating shaft 31 is movably mounted on the bending plate 2, and the rotating shaft 31 is connected to the plug-in column 32, and the plug-in column 32 is plugged into the plug-in hole 14. The rotating shaft 31 and the plug-in column 32 constitute a simple hinge mechanism 3. This design is concise and clear, easy to manufacture and install, and has reliable connectivity. The rotating shaft 31 is connected to the bending plate 2, and the plug-in column 32 is plugged into the plug-in hole 14, so that the entire hinge mechanism 3 is stable and reliable.

[0029] The working principle of the utility model is as follows: when in use, the bending plate 2 is placed into the corresponding bending placement groove 13 according to the folding angle requirement of the flexible flat cable, and the square plug-in column 32 is inserted into the corresponding plug-in hole 14. Then the section of the flexible flat cable to be bent is placed into the wire limiting groove 11, and then the flexible flat cable is moved according to product requirements so that the part to be folded moves to the position of the through groove 12. Finally, the bending plate 2 is manually rotated so that the bending plate 2 rotates around the rotating shaft 31 to bend the flexible flat cable between the upper end of the bending seat 1 and the bending plate 2, and the bending of the flexible flat cable is completed.

[0030] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
