Description

Technical Field

[0001] This utility model relates to the field of fingerprint module technology, and in particular to a standardized connection structure for capacitive fingerprint modules. Background Technology

[0002] With the rapid development of technology, biometric technology is increasingly widely used in various fields. Among them, capacitive fingerprint modules, as a mature and efficient biometric technology, have become a key component for identity verification in devices such as smartphones, laptops, and smart locks due to their advantages such as high precision, high security, and slim design. In electronic device manufacturing, capacitive fingerprint modules need to achieve reliable connections with other components such as motherboards through connectors to ensure stable and efficient signal transmission.

[0003] The structure of capacitive fingerprint modules is affected by the overall space of the device. In order to avoid other components, various FPC shapes will appear. However, the structure of the fingerprint collection module that comes into contact with the finger has become more consistent. Due to the influence of FPC, the fingerprint module shape of each model must be redesigned. This not only increases the design cost and R&D cycle, but also increases the difficulty of material management on the production line and the probability of errors, resulting in a waste of resources. Utility Model Content

[0004] Based on this, it is necessary to provide a standardized connection structure for capacitive fingerprint modules to address the aforementioned technical problems. By making the fingerprint module body and the first FPC standard, only the second FPC needs to be redesigned for different complete devices. The first FPC and the second FPC are connected by a connector. This approach reduces the workload of fingerprint module design. Each fingerprint module complete device only requires redesigning the second FPC, which greatly reduces the workload, thereby reducing costs and shortening the development cycle.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A standardized connection structure for a capacitive fingerprint module includes:

[0007] The FPC body comprises a first FPC and a second FPC. One end of the first FPC is connected to the fingerprint module body, and the other end of the first FPC is detachably connected to the second FPC via a connector. The connector is installed on the side of the second FPC away from the first FPC.

[0008] Furthermore, the connector includes a female connector and a male connector that mate with each other. The female connector is installed at the end of the first FPC away from the fingerprint module body, and the male connector is installed at the end of the second FPC away from the connector head.

[0009] Furthermore, the female connector includes a first body and a plurality of slots formed on the upper surface of the first body, and the male connector includes a second body and a plug fixedly connected to the lower surface of the second body.

[0010] Furthermore, positioning grooves are provided on both the left and right sides of the upper surface of the first base, and positioning posts corresponding to the positioning grooves are fixedly connected to both the left and right sides of the lower surface of the second base.

[0011] Furthermore, the bottom end of the positioning post is provided with a rounded corner.

[0012] Furthermore, a limiting component is provided at the bottom end of the first base, the limiting component being used to confine the positioning post inside the positioning groove.

[0013] Furthermore, the limiting component includes a movable plate, on which a through hole corresponding to the positioning post is formed. A slanted groove is formed on the side of the positioning post. A rounded corner is formed on the side of the through hole near the slanted groove. A cavity communicating with the positioning groove is formed inside the first base. One end of the movable plate is located inside the cavity. The other end of the movable plate passes through the first base and is threaded with an adjusting screw.

[0014] Furthermore, the movable plate is slidably connected to the first base body, and a fixed base is fixedly connected to one end of the movable plate located on the outside of the first base body. The adjusting screw is threadedly connected to the fixed base.

[0015] Furthermore, the cavity extends through the lower surface of the first seat, and cover plates are fixedly connected to both the left and right sides of the lower surface of the first seat by fixing screws.

[0016] Furthermore, the movable plate is provided with clearance holes corresponding to the fixing screws.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The standardized connection structure for capacitive fingerprint modules provided by this utility model makes the fingerprint module body and the first FPC standard products. For different complete machines, only the second FPC needs to be redesigned. The first FPC and the second FPC are connected by a connector. By adopting this method, the workload of fingerprint module design is reduced. Each fingerprint module complete machine only needs to redesign the second FPC, which greatly reduces the workload and shortens the development cycle.

[0019] The standardized connection structure for capacitive fingerprint modules provided by this utility model features a limiting component at the bottom of the first base. When the plug on the male connector is inserted into the slot on the female connector, the positioning pin is inserted into the positioning groove. Then, the adjusting screw is rotated using a tool. Since the adjusting screw is threadedly connected to the fixed base, it can drive the fixed base and the movable plate to move to the right during the rotation. At this time, the rounded corner at the through hole compresses the inclined groove, thereby restricting the positioning pin inside the positioning groove. This prevents the first and second FPCs from pulling each other, which could cause the female connector and the male connector to detach. This results in better stability during use.

The female connector 7 is installed at the end of the first FPC3 away from the fingerprint module body 2, and the male connector 8 is installed at the end of the second FPC4 away from the connector head 6.

[0046] The female connector 7 includes a first body 701 and a plurality of slots 702 formed on the upper surface of the first body 701.

[0047] Example 3

[0048] The standardized connection structure of the capacitive fingerprint module provided in Embodiment 1 or 2 is further optimized, such as... Figure 7 and Figure 8 As shown, positioning grooves 703 are provided on both the left and right sides of the upper surface of the first base 701, and positioning posts 803 corresponding to the positioning grooves 703 are fixedly connected to both the left and right sides of the lower surface of the second base 801; the bottom end of the positioning post 803 is provided with a rounded corner; when the plug 802 on the male connector 8 is inserted into the slot 702 on the female connector 7, the rounded corner at the bottom of the positioning post 803 facilitates guidance and quickly inserts the positioning post 803 into the positioning groove 703;

[0049] The bottom end of the first base 701 is provided with a limiting component, which is used to restrict the positioning post 803 inside the positioning groove 703.

[0050] Example 4

[0051] The standardized connection structure of the capacitive fingerprint module provided in the above embodiments is further optimized, such as... Figure 4-8 As shown, the limiting component includes a movable plate 901, on which a through hole 902 corresponding to a positioning post 803 is opened. A slanted groove 903 is opened on the side of the positioning post 803. A rounded corner is opened on the side of the through hole 902 near the slanted groove 903. A cavity 905 communicating with the positioning groove 703 is opened inside the first seat 701. One end of the movable plate 901 is located inside the cavity 905. The other end of the movable plate 901 passes through the first seat 701 and is threadedly connected to an adjusting screw 906. The left side of the adjusting screw 906 contacts the connecting female seat 7 or is rotatably connected through a bearing.

[0052] The movable plate 901 is slidably connected to the first base 701. A fixed base 907 is fixedly connected to one end of the movable plate 901 located outside the first base 701. The adjusting screw 906 is threadedly connected to the fixed base 907.

[0053] The cavity 905 penetrates the lower surface of the first seat 701. The left and right sides of the lower surface of the first seat 701 are fixedly connected to the cover plate 909 by fixing screws 908. The bottom left side of the movable plate 901 is fixedly connected to the fixing block and contacts the cover plate 909, and will not move up and down.

[0054] The movable plate 901 has a clearance hole 910 corresponding to the fixing screw 908. With this structural design, the adjusting screw 906 can drive the fixed seat 907 and the movable plate 901 to move to the right during rotation. At this time, the clearance hole 910 will not contact the fixing screw 908 and will not affect the movement of the movable plate 901. At the same time, when the connecting female seat 7 and the connecting male seat 8 are not connected, the fixing screw 908 blocks the movable plate 901 and will not cause the movable plate 901 to detach from the connecting female seat 7.

[0055] The usage process of the standardized connection structure for the capacitive fingerprint module provided by this utility model is as follows:

[0056] When in use, the movable plate 901 is positioned on the far left. Then, the plug 802 on the male connector 8 is inserted into the slot 702 on the female connector 7, and the positioning pin 803 is inserted into the positioning groove 703. Then, the adjusting screw 906 is rotated using a tool. Since the adjusting screw 906 is threadedly connected to the fixed seat 907, the adjusting screw 906 can drive the fixed seat 907 and the movable plate 901 to move to the right during the rotation. At this time, the rounded corner at the through hole 902 compresses the inclined groove 903, thereby restricting the positioning pin 803 inside the positioning groove 703, preventing the first FPC3 and the second FPC4 from pulling and causing the female connector 7 and the male connector 8 to separate, resulting in better stability during use.
