Description

Technical Field

[0001] The utility model belongs to the field of FPC, and particularly relates to an FPC component. Background Art

[0002] A flexible printed circuit board (FPC for short) is a highly reliable and extremely flexible printed circuit board made of polyimide or polyester film; it has the characteristics of high wiring density, light weight, thin thickness, and good bendability. FPC is commonly used to connect functional structures such as display screens, touch screens, camera modules, batteries, and sensors. However, due to its soft nature, FPC cannot be used as the bearing structure for these functional structures. In the prior art, it is mostly achieved by connecting the bearing functional structure on one side of the PCB, welding the FPC to the PCB, electrically connecting the PCB to the functional structure through the FPC, and finally electrically connecting to the external device through the connector welded on the other side of the PCB, so as to realize the electrical connection between the functional structure and the external device. However, this structural design not only results in low assembly efficiency but also high labor costs and material costs. Summary of the Utility Model

[0003] In order to solve the above problems, the purpose of the utility model is to provide an FPC component with high assembly efficiency and low labor costs and material costs.

[0004] In order to achieve the above purpose, the technical solution of the utility model is as follows.

[0005] An FPC component, which includes:

[0006] A bearing body, on one side of the bearing body, there is a bearing position for bearing external functional structures, and on the other side of the bearing body, there is a connection position;

[0007] An FPC, on the FPC, there are an FPC main body, a first connection end, and a second connection end for electrically connecting to an external functional structure. Both the first connection end and the second connection end are connected to the FPC main body. The FPC main body is arranged on the other side of the bearing body. On the first connection end, there are electrical connection holes for electrical connection, and the electrical connection holes correspond to the connection positions.

[0008] In this FPC component, during its assembly, place the FPC on the bearing body so that the electrical interface is aligned with the connection position. When in use, pass the connection end of the external connector through the electrical interface and install it on the connection position, install the external functional structure on the bearing position of the bearing body, and then electrically plug the second connection end of the FPC into the external functional structure on the bearing position to complete the assembly of the FPC component with the external connector and the external functional structure.

[0009] Based on the structural design of the FPC component, firstly, the carrier body is used to replace the carrying function of the PCB, which can greatly reduce the material cost; secondly, when assembling the FPC component, only the FPC needs to be placed on the carrier body so that the electrical interface is aligned with the connection position; and when assembling the FPC component with an external connector, only the connection end of the external connector needs to pass through the electrical interface and then be installed on the connection position, so that while the external connector is electrically connected to the FPC, the physical connection between the connector and the carrier body can be achieved. At the same time, the FPC will be further fixed on the carrier body through the external connector, so that the FPC component has higher assembly efficiency during both assembly and connection to other external structures, reducing the assembly time cost and thus achieving a reduction in labor costs.

[0010] Furthermore, positioning posts are provided on one side of the carrier body, and positioning holes are provided at the first connection end or on the FPC body, and the positioning posts are inserted into the positioning holes. The setting of the positioning posts is used for positioning when the FPC is installed on the carrier body, facilitating the installation of the FPC.

[0011] Furthermore, the connection position is a hole that penetrates both sides of the carrier body, and the electrical connection hole is correspondingly connected to the connection position. The connection end of the external connector directly passes through the electrical interface and the connection position to simultaneously achieve electrical connection and physical connection, making the installation more convenient.

[0012] Furthermore, the first connection end includes two connection parts and a connecting part. The two connection parts are connected by the connecting part, and one of the connection parts is connected to the FPC body;

[0013] The electrical connection hole is provided on any one of the connection parts, and the other connection part is provided with a physical connection hole for physical connection. The two connection parts are respectively arranged on both sides of the carrier body, and the physical connection hole and the electrical connection hole are respectively connected to both sides of the connection position. This setting enables the external connector to pass through the physical connection hole, the connection position, and the electrical connection hole in sequence, or pass through the electrical connection hole, the connection position, and the physical connection hole in sequence when being installed. This structural setting makes the connection between the external connector, the FPC, and the carrier body more stable.

[0014] Furthermore, the first connection end includes two connection parts and a connecting part. The two connection parts are connected by the connecting part, and one of the connection parts is connected to the FPC body;

[0015] The electrical connection holes are provided on both of the two connecting parts. The two connecting parts are respectively arranged on both sides of the bearing body, and the electrical connection holes of the two connecting parts are respectively connected to both sides of the connection position. This setting enables the external connector to pass through the electrical connection hole, the connection position, and the electrical connection hole in sequence during installation. This structural setting makes the connection between the external connector, the FPC, and the bearing body more stable.

[0016] Furthermore, positioning posts are provided on both sides of the bearing body, and positioning holes are provided on both of the two connecting parts. The positioning posts on both sides of the bearing body are respectively inserted into the positioning holes of the two connecting parts. The setting of the positioning posts on both sides of the bearing body further improves the connection stability between the bearing body and the FPC.

[0017] Furthermore, an avoidance hole is provided on the bearing body, and the second connection end passes through the avoidance hole and extends to the bearing position.

[0018] Furthermore, the bearing position includes a bearing groove provided on one side of the bearing body.

[0019] Furthermore, installation grooves are provided on the bearing body corresponding to the FPC body and the first connection end. The FPC body and the first connection end are arranged in the installation grooves, and the connection position is located in the installation grooves.

[0020] Furthermore, the bearing body is made of an insulating material. This insulating material can be materials such as plastics.

[0021] The beneficial effects of the present utility model are as follows. Based on the structural design of this FPC component, firstly, the bearing function of the PCB is replaced by the bearing body, which can greatly reduce the material cost; secondly, when assembling this FPC component, only the FPC needs to be placed on the bearing body so that the electrical interface is aligned with the connection position; and when assembling this FPC component with an external connector, only the connection end of the external connector needs to pass through the electrical interface and then be installed on the connection position, so that while the external connector is electrically connected to the FPC, the physical connection between the connector and the bearing body can be realized, and at the same time, the FPC will be further fixed on the bearing body through the external connector, making the assembly efficiency of this FPC component very high both during assembly and when connecting to other external structures, so as to reduce the assembly time cost and further reduce the labor cost.
