Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic equipment technology, specifically to an easy-assembly protective structure for an FPC used in cameras. Background Technology
[0002] The gold fingers are the exposed conductors at both ends of an FPC (Flexible Printed Circuit) cable. A gold conductive layer is formed on the FPC through a special process, used for assembly with the terminal blocks on the camera to achieve signal transmission and electrical connection in the camera. Because the surface of its solder pads is made of immersion gold or gold plating, and the conductive contacts are arranged like fingers, it is commonly known as "gold fingers".
[0003] Currently, there are more and more cameras with FPCs on the market. However, there is always a risk of the FPC gold fingers falling off after assembly with the terminal block on the camera. This is because the latching fit on the terminal block is only about 0.3mm, and the latching force is relatively small. Therefore, it is mostly used in consumer products. When used in automotive products, additional assistance is needed to ensure that the latches do not fall off.
[0004] Various design solutions exist in the market to address this issue, such as: 1. Adding adhesive to the FPC and bonding it to the camera housing; 2. Directly applying adhesive to fix the FPC to the terminal block; 3. Applying electrical tape to the circuit board to secure the clips on the terminal block. These three solutions have drawbacks. For example, adding adhesive to the FPC and directly applying adhesive to fix the FPC to the terminal block are difficult to rework and can easily damage the FPC or terminal block; applying electrical tape to the circuit board to secure the clips also carries the risk of the tape detaching. Detachable FPC gold fingers can lead to product malfunction and quality issues, which is unacceptable in a highly competitive market. Utility Model Content
[0005] In view of the deficiencies in the prior art, the purpose of this utility model is to provide an easy-to-assemble protective structure for FPC used in cameras, which can prevent the gold fingers of the FPC from falling off the terminal block and facilitate rework in case of production abnormalities.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: it is used in conjunction with a bottom shell, a circuit board, a terminal block, and an FPC, wherein a buckle is provided on the terminal block, and the FPC is disposed between the terminal block and the buckle. The feature is that it further includes a pressing member, wherein the first contact surface of the pressing member contacts the inner bottom wall of the bottom shell, and the second contact surface of the pressing member contacts the top surface of the buckle.
[0007] Furthermore, the pressing element is EPDM foam.
[0008] Furthermore, the second contact surface of the pressing member also contacts the top surface of the terminal block.
[0009] Furthermore, the interference between the pressing element and the bottom shell is 0.05-0.15mm.
[0010] Furthermore, the circuit board has a longitudinal through-hole, through which the FPC passes.
[0011] Furthermore, it also includes a dustproof pad, which is inserted into the socket, and the FPC is located inside the socket, with the FPC in close contact with both the inner wall of the socket and the dustproof pad.
[0012] Furthermore, at least one contact surface of the pressing member is provided with adhesive backing.
[0013] Furthermore, the adhesive backing includes a first adhesive backing and a second adhesive backing, wherein the first adhesive backing is disposed on the first contact surface and the second adhesive backing is disposed on the second contact surface.
[0014] Furthermore, the shape of the pressing element is adapted to the shape of the terminal block.
[0015] Furthermore, the inner bottom wall of the bottom shell is provided with a protrusion.
[0016] The beneficial effects of this utility model are as follows: This utility model provides an easy-to-assemble protective structure for FPC used in cameras. A pressing component is designed between the bottom shell and the terminal block. After the bottom shell and the top shell are assembled, the second contact surface of the pressing component will apply pressure to the top surface of the buckle, thereby eliminating the risk of the buckle popping open. In case of production abnormalities, it is easy to rework, and the pressing component can be removed directly. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0020] In this application, unless otherwise expressly specified and limited, the terms "connection" and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0021] In the description of this application, it should be understood that the terms "longitudinal", "horizontal", "level", "top", "bottom", "upper", "lower", "inner" and "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0022] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.
[0023] like Figures 1-5 As shown, this utility model provides an easy-to-assemble protective structure for an FPC used in cameras, which is used in conjunction with a bottom shell 10, a circuit board 20, a front shell 30, a terminal block 40, an FPC 50, and a camera 60. The terminal block 40 is provided with a buckle 41, and the FPC 50 is disposed between the terminal block 40 and the buckle 41. The camera 60 is electrically connected to the FPC 50. The above contents are all prior art, and the specific structure will not be described in detail here.
[0024] This utility model also includes a pressing member 70, which is disposed between the bottom shell 10 and the buckle 41. The first contact surface of the pressing member 70 contacts the inner bottom wall of the bottom shell 10, and the second contact surface of the pressing member 70 contacts the top surface of the buckle 41.
[0025] The specific usage process of this utility model is as follows: First, the operator assembles the FPC50 and the terminal block 40; then, the pressing member 70 is placed between the bottom shell 10 and the buckle 41, so that the first contact surface of the pressing member 70 contacts the inner bottom wall of the bottom shell 10, and the second contact surface of the pressing member 70 contacts the top surface of the buckle 41; then, the bottom shell 10 and the front shell 30 are assembled together. At this time, the second contact surface of the pressing member 70 will apply pressure to the top surface of the buckle 41, so that the buckle 41 has no risk of popping open.
[0026] This structure is easy to rework in case of production abnormalities; simply remove the pressing part 70, which is very convenient to operate.
[0027] In one embodiment, the pressing element 70 is EPDM foam. EPDM foam is a high-performance elastomer material that can quickly return to its original shape after being subjected to force, is not easily deformed or broken, and can better withstand the pressure between the bottom shell 10 and the terminal block 40.
[0028] In one embodiment, the second contact surface of the pressing member 70 also contacts the top surface of the terminal block 40, and the size of the pressing member 70 is comparable to the size of the terminal block 40.
[0029] This design allows the pressing element 70 to contact the terminal block 40 and the latch 41 simultaneously, resulting in greater stability.
[0030] In one embodiment, the interference between the pressing member 70 and the bottom shell 10 is 0.05-0.15mm to ensure that the bottom shell 10 can stably press down on the pressing member 70.
[0031] In one embodiment, the circuit board 20 has a longitudinally penetrating slot 21 through which the FPC 50 passes.
[0032] In this embodiment, a dustproof pad 80 is also included. The dustproof pad 80 is inserted into the socket 21. The FPC 50 is located inside the socket 21. The FPC 50 is in close contact with the inner wall of the socket 21 and the dustproof pad 80.
[0033] In its initial state, the dust pad 80 is not inserted into the socket 21.
[0034] When using this utility model, the operator first passes the FPC50 through the socket 21, then assembles the FPC gold fingers with the terminal block 40, and then inserts the dustproof pad 80 into the socket 21. At this time, the FPC50 is confined inside the socket 21, and the FPC50 is in close contact with the inner wall of the socket 21 and the dustproof pad 80.
[0035] This design not only secures the FPC50, further improving the stability between the FPC gold fingers and the terminal block 40, but also provides dust protection.
[0036] In one embodiment, at least one contact surface of the pressing member 70 is provided with adhesive backing.
[0037] In this embodiment, the adhesive backing includes a first adhesive backing and a second adhesive backing, with the first adhesive backing disposed on the first contact surface and the second adhesive backing disposed on the second contact surface.
[0038] The design of the first adhesive backing can further improve the adhesion between the first contact surface of the pressing part 70 and the inner bottom wall of the bottom shell 10, and the design of the second adhesive backing can further improve the adhesion between the second contact surface of the pressing part 70 and the top surface of the buckle 41, thereby further improving the stability of the overall structure. At the same time, it does not prevent workers from removing the pressing part 70 during rework. In addition, the adhesive backing does not come into direct contact with the FPC, so it will not cause the PFC to tear when rework is required, thus avoiding the scrapping of parts and increasing rework costs.
[0039] Furthermore, the shape of the pressing member 70 is adapted to the shape of the terminal block 40 to further improve the adaptability of this structure.
[0040] Furthermore, the inner bottom wall of the bottom shell 10 is provided with a protrusion so that the contact distance between the inner bottom wall of the bottom shell 10 and the first contact surface is shorter, which facilitates assembly.
[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.
[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
