In order to enable personnel in this technical field to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0055] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0056] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0057] Please refer to Figure 1-Figure 9 As shown, a structure for preventing a ZIF plug-in FPC from falling off, an FPC body 1, a main screen BTB connector 11 is provided at one end of the FPC body, and a ZIF interface 12 is provided at the other end of the FPC body;

[0058] A fixing ear 13 is formed by extending outwardly from the outer side of the FPC body 1;

[0059] A PCB board 3 having a ZIF connector 31 thereon for connection with the ZIF interface 12 on the FPC body 1;

[0060] A positioning hole 32, which is provided at a position of the PCB board 3 corresponding to the fixing ear 13;

[0061] A fixing element 2, which is provided on the PCB board 3 and the FPC body 1 and is used to fasten the connection between the ZIF interface 12 and the ZIF connector 31;

[0062] The fixing element 2 includes a support plate 21, support columns 22 fixed at both ends of the support plate 21, and a clamping piece 23 which is jointly sleeved on the surface of the support column 22. Guide grooves 24 are provided on both sides of the support column 22, and a plurality of positioning buckles 25 are evenly spaced and distributed in the guide grooves 24. The support plate 21 is located on the back side of the PCB board 3, and the support column 22 passes through the positioning hole 32 and the fixing ear 13 in sequence to be connected with the clamping piece 23.

[0063] The clamping member 23 includes a clamping plate 230, and the clamping plate 230 has through slots 231 at positions corresponding to the two support columns 22. The clamping plate 230 is sleeved on the surfaces of the two support columns 22 through the through slots 231 and is pressed against the fixing ears 13. This embodiment provides a structure for preventing the ZIF plug-in FPC from falling off;

[0064] A support sheet 232 is fixed in the through slot 231 , and an elastic buckle sheet 233 is fixed at one end of the support sheet 232 . The elastic buckle sheet 233 abuts against the bottom of the positioning buckle 25 to lock the pressing plate 230 .

[0065] After one end of the FPC body 1 is plugged and installed with the ZIF connector 31 on the PCB board 3 through the ZIF interface 12, the fixing ear 13 on the FPC body is aligned with the positioning hole 32 opened on the PCB board 3, and then the support plate 21 is placed on the back of the PCB board 3 and the support column 22 on it passes through the positioning hole 32 and the fixing ear 13 in sequence, and then the pressing plate 230 is buckled on the surface of the support column 22 through the through slot 231 and slides toward the fixing ear 13. During the sliding process, the pressing plate 23 The elastic buckle piece 233 on 0 will come into conflict with the corresponding positioning buckle 25 and deform to avoid it, so that the clamping plate 230 can continue to slide. When the clamping plate 230 slides and comes into conflict with the surface of the fixing ear 13 and the FPC body 1, the elastic buckle piece 233 is just located between the two adjacent positioning buckles 25, forming a quick installation and positioning of the clamping plate 230. At the same time, the effect of secondary fixing the FPC body 1 and the PCB board 3 is also achieved, avoiding functional problems such as signal transmission interruption caused by the detachment of the ZIF interface 12 and the ZIF connector 31.

[0066] The structure for preventing the ZIF plug-in FPC from falling off provided in Example 1 is further optimized. Specifically, Figure 4As shown, the support column 22 is also provided with an anti-falling element 4 for further locking the fixing element 2;

[0067] The anti-falling element 4 includes a horizontal groove 41 formed on the support column 22 and a fastener sleeved on the support column 22, and one end of the horizontal groove 41 is connected to the guide groove 24;

[0068] The fastener includes a fixing buckle 42 sleeved on the surface of the support column 22, a slider 43 is fixed inside the fixing buckle 42, and the fixing buckle 42 is rotated to make the slider 43 slide from the guide groove 24 into the horizontal groove 41 to lock the surface of the support column 22. A spring 44 is also sleeved on the surface of the support column 22, one end of the spring 44 is supported on the surface of the pressing member 23, and the other end is against the bottom of the fixing buckle 42;

[0069] In the first embodiment, the clamping plate 230 is slid on the surface of the support column 22 to achieve rapid fixation in place. In order to ensure the stable positioning of the clamping plate 230 itself, an anti-dropping element 4 is provided.

[0070] Specifically, after the clamping plate 230 begins to be clamped into place, the spring 44 is sleeved on the support column 22, and then the slider 43 on the fixing buckle 42 is slid downward along the direction of the guide groove 24 (the slider 43 will not hinder the movement of the positioning buckle 25). When the fixing buckle 42 slides and contacts the surface of the clamping plate 230 (the spring 44 is in a compressed state at this time), the slider 43 is just located on one side of the horizontal groove 41. By rotating the fixing buckle 42 on the surface of the support column 22, the slider 43 slides in the horizontal groove 41. The fixing buckle 42 is released, and the slider 43 is supported upward by the spring 44, so that it is stable in the horizontal groove 41, thereby ensuring the stability of the fixed state of the fixing buckle 42, thereby achieving further fixation of the clamping plate 230 and ensuring the further stability of the connection between the ZIF interface 12 and the ZIF connector 31.

[0071] The structure for preventing the ZIF plug-in FPC from falling off provided in Example 1 or 2 is further optimized, such as Figure 4 , Figure 5 and Figure 6 As shown, the height of the horizontal groove 41 is twice the height of the slider 43;

[0072] A locking knob 45 is fixed to the top of the slider 43, a locking groove is formed on the top wall of the horizontal groove 41 corresponding to the surface of the locking knob 45, and the surfaces of the support plate 21, the pressing plate 230 and the support column 22 are all coated with insulating paint;

[0073] In Example 2, after the fixing buckle 42 is slid into the surface of the clamping plate 230, the top height of the slider 43 is lower than the top wall height of the horizontal groove 41. At this time, after the slider 43 is rotated in the horizontal groove 41, the locking protruding button 45 on the slider 43 will not form a movement obstacle with the horizontal groove 41. When the slider 43 completely slides into the horizontal groove 41, the fixing buckle 42 is released, and the slider 43 is moved up through the support of the spring 44, and the locking protruding button 45 on the slider 43 is engaged with the corresponding locking groove (not shown in the figure). The locking protruding button 45 and the locking groove are locked with each other, thereby ensuring that the slider 43 is stably engaged in the horizontal groove 41.

[0074] The use process of the structure for preventing the ZIF plug-in FPC from falling off provided by the utility model is as follows: after one end of the FPC body 1 is plugged and installed with the ZIF connector 31 on the PCB board 3 through the ZIF interface 12, the support plate 21 is placed on the back of the PCB board 3 and the support column 22 on it passes through the positioning hole 32 and the fixing ear 13 in sequence, and then the clamping plate 230 is buckled on the surface of the support column 22 through the through groove 231, and is made to abut against the fixing ear 13 and the surface of the FPC body 1, forming a quick installation and positioning of the clamping plate 230, and then the spring 44 is sleeved on the support column 22, and then the slider 43 on the fixing buckle 42 is slid downward along the direction of the guide groove 24 so that it is on the surface of the clamping plate 230, the fixing buckle 42 is rotated to make the slider 43 slide in the horizontal groove 41, and the fixing buckle 42 is released, so that the locking convex button 45 on the slider 43 is engaged in the corresponding locking groove, thereby completing the strengthening and fastening of the connection between the FPC body 1 and the PCB board 3.
