Abstract
Description
Technical Field
[0001] This utility model relates to the field of FPC lateral support technology, and in particular to an FPC lateral positioning and mounting bracket. Background Technology
[0002] With the trend towards compactness and lightweighting of electronic devices, flexible printed circuit boards (FPCs) are widely used in various electronic devices due to their excellent flexibility and bendability.
[0003] Currently, snap-fit mounting is one of the mainstream installation methods for FPCs. Specifically, the central area of the FPC is in a free-suspension state, and the two ends of the FPC are clamped by snap-fit structures at both ends of the bracket to achieve positioning. However, due to the lack of effective fixing points for the FPC, displacement is prone to occur under vibration or impact, leading to poor contact. Furthermore, the angle and thickness of the snap-fit need to be precisely matched with the stiffness of the FPC, and different specifications of FPCs require redesigned brackets, resulting in an increase in NRE (non-recurring engineering costs). Utility Model Content
[0004] Based on this, the present invention provides an FPC lateral positioning mounting bracket.
[0005] To achieve the objectives of this utility model, the following technical solution is adopted:
[0006] An FPC lateral positioning mounting bracket, comprising:
[0007] The main body of the support frame includes side plates and a support plate extending vertically from one side of the bottom of the side plates; and
[0008] A clamping assembly is movably mounted on the main body of the bracket; the clamping assembly includes a rotating shaft that slides to connect the support plate, a pressure roller rotatably mounted on the rotating shaft, and a tension spring connecting the rotating shaft and the support plate; the pressure roller and the side plate are used to clamp the FPC.
[0009] The aforementioned FPC lateral positioning mounting bracket has a simple structure and is easy to use. The tension spring drives the pressure roller to elastically abut against the FPC to attach the FPC to the side plate, thereby achieving lateral positioning of the FPC. At the same time, it can adapt to FPCs of different thicknesses and specifications, and provides effective support and fixation for the middle part of the FPC to avoid displacement or misalignment.
[0010] In one embodiment, the support plate is provided with a guide groove, the innermost end of which is close to the side plate and the outermost end of which is far from the side plate; a locking groove is provided on the support plate in the opposite direction to the outermost end of the guide groove; the angle between the locking groove and the guide groove is an acute angle.
[0011] In one embodiment, the rotating shaft passes through a guide groove and is connected to one end of a tension spring, while the other end of the tension spring is used to connect to a support plate.
[0012] In one embodiment, a fixing post is connected to the bottom surface of the support plate on one side corresponding to the innermost end of the guide groove; the end of the tension spring away from the pivot is used to connect to the fixing post.
[0013] In one embodiment, a plurality of anti-slip protrusions are uniformly provided on the surface of the pressure roller, and the anti-slip protrusions are coaxially arranged with the pressure roller.

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.
[0024] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.
[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0026] Please see Figures 1 to 5 The FPC lateral positioning mounting bracket according to one embodiment of the present invention includes a bracket body 10 and a clamping component 20 movably mounted on the bracket body 10.
[0027] The main body 10 of the bracket includes a side plate 11, a limiting plate 12 detachably connected to the top side of the side plate 11, a support plate 13 extending vertically from the bottom side of the side plate 11, and a transition plate 14 extending vertically from the bottom of the side plate 11 to the opposite sides of the support plate 13.
[0028] Specifically, the side plate 11 is generally L-shaped, and a clearance hole 110 is provided on the side of the side plate 11 corresponding to the support plate 13. The clearance hole 110 is used to correspond to the clamping assembly 20.
[0029] like Figure 4 As shown, the limiting plate 12 and the support plate 13 are parallel to each other, and the limiting plate 12 and the support plate 13 are used to limit the FPC. Specifically, the limiting plate 12 has an insertion hole 120 on one side; the side plate 11 has a protruding insert 111 on the top, and the insert 111 matches the insertion hole 120 to realize the detachable connection between the limiting plate 12 and the support plate 13.
[0030] In this embodiment, the width of the limiting plate 12 is greater than the thickness of the support plate 13.
[0031] The support plate 13 is provided with a guide groove 131, the innermost end of which is close to the side plate 11, and the outermost end of which is away from the side plate 11. A locking groove 132 extends in the opposite direction to the outermost end of the guide groove 131 on the support plate 13; the angle between the locking groove 132 and the guide groove 131 is an acute angle. Further, as... Figure 2 and Figure 3 As shown, a fixing post 133 is connected to one side of the bottom surface of the support plate 13 corresponding to the innermost end of the guide groove 131. The fixing post 133 is used to match and connect the clamping assembly 20.
[0032] In this embodiment, each adapter plate 14 has a through hole 140 in the middle. After the screw passes through the through hole 140, it is connected to the motherboard, so that the FPC lateral positioning mounting bracket can be fixedly installed on the motherboard.
[0033] The clamping assembly 20 includes a rotating shaft 21 that slides to connect the support plate 13, a pressure roller 22 rotatably mounted on the rotating shaft 21, and a tension spring 23 connecting the rotating shaft 21 and the support plate 13. The pressure roller 22 is used to clamp the FPC between itself and the side plate 11; the pressure roller 22 is positioned opposite to the clearance hole 110, providing a certain clearance space for the FPC while clamping and fixing it, thus preventing rigid damage to the FPC.
[0034] Specifically, such as Figure 3 and Figure 4 As shown, the rotating shaft 21 passes through the guide groove 131 and is connected to one end of the tension spring 23. The other end of the tension spring 23 is used to connect to the support plate 13, so as to drive the pressure roller 22 to always be close to the side plate 11, thereby effectively clamping and fixing the middle part of the FPC. Specifically, the end of the tension spring 23 away from the rotating shaft 21 is used to connect to the fixing post 133.
[0035] In practical use, the user can manually pull the rotating shaft 21 and pressure roller 22 outward along the guide groove 131 and embed them into the locking groove 132. At this time, the tension spring 23 is in an extended state, and the pressure roller 22 is away from the side plate 11, making it convenient to attach the FPC to the side plate 11 rather than laying it on the main board, thus achieving lateral positioning of the FPC. Then, the user manually pulls the rotating shaft 21 and pressure roller 22 away from the locking groove 132. At this time, the tension spring 23 returns to its original state, driving the rotating shaft 21 and pressure roller 22 to move along the guide groove 131 toward the side plate 11 to clamp the FPC. Compared with the traditional snap-fit fixing, this utility model uses a movable pressure roller 22, which can adapt to FPCs of different thicknesses and specifications, providing effective support and fixation for the middle of the FPC, avoiding displacement or poor release.
[0036] In this embodiment, a plurality of anti-slip raised rings are uniformly provided on the surface of the pressure roller 22. The anti-slip raised rings are coaxially arranged with the pressure roller 22 to improve the positioning and clamping effect on the FPC. It can be understood that in other embodiments, the surface of the pressure roller 22 may also be provided with anti-slip bumps or anti-slip protrusions, as long as they can achieve the same anti-slip effect.
[0037] The above-mentioned FPC lateral positioning mounting bracket has a simple structure and is easy to use. The tension spring 23 drives the pressure roller 22 to elastically abut against the FPC to attach the FPC to the side plate 11, thereby achieving lateral positioning of the FPC. At the same time, it can adapt to FPCs of different thicknesses and specifications, and provides effective support and fixation for the middle part of the FPC to avoid displacement or misalignment.
[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
