[0026] Currently, the FPC board and the PCB board need to be connected through a connector. However, this method not only requires the cost of a connector, but also the cost of soldering the connector. In addition, during the soldering process, the connector may be offset from the PCB board, resulting in poor transmission.
[0027] In view of the above problems, an embodiment of the present application provides a connection structure between an FPC board and a PCB board, which can complete the connection between the FPC board and the PCB board without a connector, thereby reducing production costs.
[0028] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.
[0029] See also Figure 1 , Figure 2 and Figure 3 A connection structure between an FPC board and a PCB board, comprising: an FPC board 100, a connecting plate 200, a PCB board 300 and a fixing member 400, wherein the FPC board 100 is provided with a first through hole 110; the connecting plate 200 is arranged on the FPC board 100, the connecting plate 200 is provided with a second through hole 210, and the first through hole 110 is communicated with the second through hole 210; the PCB board 300 is arranged on the connecting plate 200, the PCB board 300 is provided with a third through hole 310, and the second through hole 210 is communicated with the third through hole 310; the fixing member 400 is respectively penetrated with the first through hole 110, the second through hole 210 and the third through hole 310 in sequence.
[0030] It should be noted that the hardness of the connecting plate 200 is stronger than that of the FPC board 100, which plays a role in enhancing the mechanical strength of the FPC board 100. Further, by opening the first through hole 110 on the FPC board 100, opening the second through hole 210 on the connecting plate 200, and opening the third through hole 310 on the PCB board 300, and then using the fixing member 400 to pass through the first through hole 110, the second through hole 210 and the third through hole 310, the connecting plate 200, the FPC board 100 and the PCB board 300 are fixed together, thereby replacing the traditional method of connecting the FPC board 100 and the PCB board 300 with a connector, thereby reducing the production cost.
[0031] See also Figure 3 In one embodiment, the fixing member 400 includes a clamping column 410 , which passes through the first through hole 110 , the second through hole 210 , and the third through hole 310 in sequence, and a hollow portion 411 is opened on the clamping column 410 .
[0032] It should be noted that the clamping column 410 is made of metal, and the hollow portion 411 is formed by cutting off the middle of the clamping column 410 to form a hollow area. In the process of inserting, the clamping column 410 can be inserted into the first through hole 110, the second through hole 210 and the third through hole 310 by pinching both sides of the clamping column 410, which is very convenient to install.
[0033] See also Figure 3 In one embodiment, the fixing member 400 further includes a boss 420 , and the boss 420 is disposed on the clamping column 410 .
[0034] It should be noted that the boss 420 is also made of metal. The boss 420 is located at the end of the clamping column 410. After the clamping column 410 is inserted into the first through hole 110, the second through hole 210 and the third through hole 310, the clamping column 410 rebounds so that the boss 420 can be clamped on the PCB board 300 to lock the entire clamping column 410.
[0035] See also Figure 3 In one embodiment, the fixing member 400 further includes a supporting block 430 and a buckle block 440 , the supporting block 430 is disposed on the clamping column 410 , and the buckle block 440 is disposed on the supporting block 430 .
[0036] It should be noted that there are three support blocks 430 and buckle blocks 440, all of which are made of metal. Further, after the clamping column 410 is pressed into the first through hole 110, the second through hole 210 and the third through hole 310, the buckle block 440 will be buckled on the connecting plate 200, so that the connection between the connecting plate 200 and the PCB board 300 is more tightly connected.
[0037] See also Figure 4 and Figure 5In one embodiment, the connection structure between the FPC board and the PCB board further includes a first conductive member 500, and the first conductive member 500 penetrates the first through hole 110 and the second through hole 210 in sequence.
[0038] It should be noted that the first conductive member 500 is a metal ring with circular bosses on the top and bottom. The upper circular boss is buckled on the connecting plate 200, and the lower circular boss is placed on the PCB board 300. The metal ring is generally made of copper or other materials with good conductivity. The purpose of setting the first conductive member 500 is to enhance the conductive effect of the wiring of the PCB board 300 and the FPC board 100. Furthermore, the first conductive member 500 will be partially exposed on the connecting plate 200, so that the buckle block 440 will be pressed on the first conductive member 500, thereby making the first conductive member 500 more fit.
[0039] In one embodiment, the connection structure between the FPC board and the PCB board also includes a second conductive member and a third conductive member, wherein the second conductive member is arranged on the hole wall of the first through hole 110, and the third conductive member is arranged on the hole wall of the second through hole, and the second conductive member is connected to the third conductive member.
[0040] It should be noted that the second conductive member and the third conductive member are metal coatings. The second conductive member is coated on the hole wall of the first through hole 110 , and the third conductive member is coated on the hole wall of the second through hole 210 . They play the same role as the first conductive member 500 .
[0041] See also Figure 2 In one embodiment, the aperture of the first through hole 110 is the same as the aperture of the second through hole 210. Specifically, the central axis of the first through hole 110 coincides with the central axis of the second through hole 210. Specifically, the first through hole 110 has a circular cross-sectional structure. Specifically, the second through hole 210 has a circular cross-sectional structure.
[0042] It should be noted that the first through hole 110 , the second through hole 210 and the third through hole 310 are all circular through holes, which are of equal size and flush with each other.
