[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.
[0024] A plug-in FPC structure, refer to Figure 1 , including a display module body 10, to which an FPC 20 is bound. The FPC 20 is a flexible circuit board. One end of the FPC 20 is bound to the display module body 10, and the other end of the FPC 20 is used to connect with the connector of the terminal host. The end of the FPC 20 away from the display module body 10 is provided with a plug-in end 21 for connecting with the connector of the terminal host, and the plug-in end 21 is used to connect with the connector of the terminal host to ensure the normal use of the display module body 10.
[0025] Reference Figure 1 and Figure 2 FPC20 is a flexible circuit board, which is easy to bend when plugged with the connector. Therefore, a reinforcing plate 30 for enhancing hardness is provided at the plug-in end 21 of FPC20. The reinforcing plate 30 is attached to one side of the plug-in end 21. The reinforcing plate 30 is used to enhance the hardness of the plug-in end 21 so that the plug-in end 21 has a certain hardness when plugged with the connector. The two outer sides of the reinforcing plate 30 are respectively flush with the two outer edges of the FPC20.
[0026] Reference Figure 1 and Figure 3 A gold finger area 211 for contacting and connecting with the connector on the terminal host is provided at one end of the plug-in end 21 away from the reinforcement plate 30. The reinforcement plate 30 is located on the side of the plug-in end 21 away from the gold finger area 211, and is used to provide hardness for the gold finger area 211, so as to provide hardness support when the gold finger area 211 extends into the connector and contacts and connects with the connector, thereby preventing the gold finger area 211 from bending.
[0027] Further, refer to Figure 1 and Figure 2 The size of the reinforcing plate 30 is larger than that of the gold finger area 211, so that the gold finger area 211 and the area of the FPC 20 close to the gold finger area 211 are both supported by hardness, which facilitates the insertion of the FPC 20 with the connector when it is held.
[0028] Further, refer to Figure 1 and Figure 3An effective contact area 2111 is provided on the gold finger area 211. The effective contact area 2111 is the effective contact area between the gold finger area 211 and the connector. The size of the effective contact area 2111 is smaller than the size of the gold finger area 211. When the effective contact area 2111 on the gold finger area 211 is completely in contact with the connector, it can effectively ensure that the FPC20 and the connector are in good contact.
[0029] Reference Figure 1 and Figure 3 A stopper 31 is provided on the outer side of the reinforcing plate 30 to ensure that the effective contact area 2111 is fully inserted into the connector. The stopper 31 is located on the outer side of the reinforcing plate 30 , that is, on the outer edge of the FPC 20 .
[0030] Reference Figure 1 and Figure 3 The stopper 31 is a convex block protruding from the outside of the reinforcing plate 30. The cross section of the stopper 31 is triangular. The width of the stopper 31 is 1.0 mm, and the height of the stopper 31 is 1.2 mm. The thickness of the stopper 31 is the same as the thickness of the reinforcing plate 30. The stopper 31 is provided with a rounded corner at the corner away from the reinforcing plate 30, and the rounded corner radius of the stopper 31 is 0.2 mm.
[0031] Reference Figure 1 and Figure 3 There are two limiters 31, which are located at two opposite outer sides of the reinforcing plate 30, and the two limiters 31 are located at two sides of the reinforcing plate 30 relative to the effective contact area 2111, and the two limiters 31 are symmetrically arranged. The position of the limiter 31 is located at the position of the reinforcing plate 30 close to the effective contact area 2111, and the two limiters 31 are adjacent to the effective contact area 2111. The height of the limiter 31 is the same as the width of the gold finger area 211 exceeding the effective contact area 2111, and the upper end of the limiter 31 is flush with the upper edge of the gold finger area 211. When the gold finger area 211 is plugged into the connector, the effective contact area 2111 is fully extended into the connector and contacts the connector. At this time, the two limiters 31 are respectively in contact with the two outer sides of the connector to ensure that the effective contact area 2111 is fully inserted into the connector, and the problem of crooked insertion of the FPC 20 can be avoided.
[0032] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
