A PCB board is set on one side of the display screen, and the FPC is plugged into the corresponding position on the PCB board to ensure the normal use of the display screen. The display screen needs to use a protective iron frame to protect components such as capacitors and resistors on the PCB board. The protective iron frame can prevent the components from falling off due to impact or wear, and the metal protective iron frame can also play an electromagnetic shielding effect.

[0003] In the prior art, the iron frame has an opening at the position where the PCB and the FPC are plugged in, so as to facilitate the plugging of the FPC. However, the opening of the iron frame is generally a rectangular opening, and in order to achieve a good shielding effect, the opening size is slightly larger than the position where the FPC is plugged in, which will cause the fingers of employees to be blocked when assembling the FPC, which is not conducive to the plugging of the FPC and is easy to cut the fingers of employees when assembling the FPC.

[0022] 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.

[0023] A kind of iron frame opening structure for protecting FPC, refer to Figure 1 , including a PCB board 10 and an iron frame 20 disposed on one side of the PCB board 10, the iron frame 20 having an opening 21 on the side facing the PCB board 10. The PCB board 10 is provided with a connector 11 for plugging in the FPC 30, the opening 21 of the iron frame 20 is opened relative to the position of the connector 11, and the FPC 30 extends from the opening 21 to be plugged in with the connector 11 on the PCB board 10.

[0024] Reference Figure 1 One side of the opening 21 is connected to the outside world, one side of the iron frame 20 is connected to the outside world through the opening 21, and the side of the opening 21 connected to the outside world is an insertion port 22, which is used for the FPC 30 to be inserted into the opening 21 for connection.

[0025] Reference Figure 1 Since the size of the opening 21 and the insertion opening 22 are the same, they are slightly larger than the size of the connector 11, so that when the employee holds the FPC 30 and inserts it into the opening 21, his fingers will be blocked, which is not conducive to plugging and is easy to be cut by the iron frame 20 on both sides of the opening 21. Therefore, the iron frame 20 is extended outward relative to both sides of the insertion opening 22, so that the insertion opening 22 and the opening 21 are arranged in a trapezoidal shape, and the size of the insertion opening 22 is larger than the size of the opening 21, so that the FPC 30 has a larger space when it is inserted from the insertion opening 22, so that it is convenient to insert it into the opening 21 for plugging.

[0026] Reference Figure 1 The iron frame 20 is provided with outward chamfers 23 on both outer sides relative to the insertion opening 22. The chamfers 23 on both outer sides of the iron frame 20 relative to the insertion opening 22 make the insertion opening 22 open in a trapezoidal shape. The positions of the two chamfers 23 both extend from the half of the opening 21 to the lower edge of the iron frame 20, that is, the chamfers 23 extend downward from the half of the opening 21 to the edge of the insertion opening 22.

[0027] Reference Figure 1The chamfer 23 is set at a 45° angle, and the chamfer 23 makes the two sides of the insertion port 22 open at a 45° angle. The position of the iron frame 20 relative to the insertion port 22 is set at a 45° angle with the lower edge of the iron frame 20. The iron frame 20 is chamfered 23 on both sides relative to the insertion port 22, so that the size of the insertion port 22 is larger than the size of the opening 21, so that it is convenient for employees to hold the FPC 30 and insert the FPC 30 from the insertion port 22 to plug the FPC 30 into the connector 11 in the opening 21. The space in the insertion port 22 is large, which will not affect the finger operation and will not cut the finger.

[0028] Further, refer to Figure 1 and Figure 2 The iron frame 20 is provided with folded edges 40 on both sides relative to the insertion port 22. The folded edges 40 are bent from the upper surface of the iron frame 20 to the insertion port 22. The folded edges 40 are bent at 90 degrees, and the bending part of the folded edges 40 is set in a circular arc. Both sides of the iron frame 20 relative to the insertion port 22 are the bending parts of the folded edges 40. The folded edges 40 prevent the front edge of the iron frame 20 from being exposed to the outside, so that employees will not be cut by the iron frames 20 on both sides when holding the FPC 30 and inserting it into the insertion port 22.

[0029] Further, refer to Figure 1 and Figure 2 The distance between the iron frame 20 and the connector 11 on both sides of the opening 21 is 2mm-3mm, and the distance between the iron frame 20 and the outside of the FPC 30 on both sides of the insertion port 22 is 1cm-2cm, so that the employee has sufficient space to hold the FPC 30 and insert it into the insertion port 22.

[0030] In one embodiment, referring to Figure 2 Foam 50 is attached to the folded edges 40 on both sides of the iron frame 20 relative to the insertion opening 22 , and the foam 50 is attached to the bending part of the folded edges 40 to protect the fingers of the employees and the FPC 30 inserted into the insertion opening 22 .

[0031] Reference Figure 1 and Figure 2 By widening the opening 21 and the insertion port 22 of the connector 11 on the PCB board 10, the iron frame 20 is chamfered 23 on both sides of the insertion port 22 where the FPC 30 is inserted, so that the size of the insertion port 22 is larger than the size of the opening 21, so that it is convenient for employees to hold the FPC 30 and insert it from the insertion port 22 to insert the FPC 30 into the opening 21 and plug it into the connector 11 on the PCB board 10. The iron frame 20 is provided with folded edges 40 on both sides relative to the insertion port 22. The arc-shaped side will not cut the fingers of employees and the FPC 30, thereby improving the efficiency of FPC 30 plugging.

[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.
