Description

Technical Field

[0001] This invention relates to the field of ribbon cable technology, and more specifically, to a method for adjusting the wiring sequence of an FPC / FFC. Background Technology

[0002] FPC / FFC has been further applied in signal loops of the automotive, industrial and commercial, and consumer electronics industries. However, the full-scale application of FPC / FFC in the energy storage battery and automotive industries still faces some obstacles. This is mainly because the loop arrangement of FPC / FFC is in a two-dimensional plane, unlike traditional wire harnesses which are three-dimensional in space and not affected by the pin order at both ends of the loop, allowing for random connections. The loop connection of a single-layer FPC / FFC can only achieve a regular N-pin to N-pin connection, but in reality, the loops at both ends are limited by the loop definitions at the device ends, resulting in a random correspondence at the output ends.

[0003] The existing solution is to use multi-panel PCBAs and adjust the wiring sequence by connecting vias on the PCBAs. This invention is highly customized and is basically for specific projects. It lacks universality and cannot achieve large-scale cost reduction by developing it into a standard product.

[0004] Therefore, there is an urgent need to invent a method for adjusting the line sequence of FPC / FFC to solve the aforementioned technical problems. Summary of the Invention

[0005] One of the objectives of this invention is to provide a wiring sequence adjustment method for FPC / FFC that addresses the shortcomings of existing technologies. This method combines the advantages of FPC / FFC and traditional conductors, meeting the requirements for high density and lightweight design while allowing for free adjustment of the wiring sequence.

[0006] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0007] A method for adjusting the wiring sequence of an FPC / FFC is provided, including the following steps:

[0008] S1. Record the wiring sequence of the first flexible circuit component, use an FPC / FFC connector to connect one end of the lines and wires of the first flexible circuit component one by one, and mark the wires to record the correspondence between the first flexible circuit component and the wires.

[0009] S2. Based on the line sequence arrangement of the first flexible circuit component, the correspondence between the first flexible circuit component and the wire, and the line sequence arrangement at the terminal, the correct line sequence arrangement of the wire is determined, and the position of the wire is adjusted according to the correct line sequence arrangement of the wire so that the line sequence arrangement of the wire matches the line sequence arrangement at the terminal.

[0010] Furthermore, it also includes step S3:

[0011] S3. Use another FPC / FFC connector to connect the other end of the wire after adjusting the wire sequence to the lines of the second flexible circuit assembly in a one-to-one correspondence, so that the lines of the second flexible circuit assembly match the wire sequence at the terminal.

[0012] Furthermore, in step S1, the number of the first flexible circuit components is at least two, and the number of FPC / FFC connectors is set to correspond to the number of the first flexible circuit components.

[0013] Furthermore, the FPC / FFC connector includes a connector body and a wire disposed at one end of the connector body. The end of the connector body away from the wire is also provided with an FPC / FFC connection port. By inserting the first flexible circuit component into the FPC / FFC connection port, the circuit of the first flexible circuit component and the wire can be connected.

[0014] Furthermore, in step S1, the FPC / FFC connector has at least two FPC / FFC connection ports, and the number of FPC / FFC connection ports corresponds to the number of the first flexible circuit components.

[0015] Furthermore, the wiring arrangement at the terminal can be freely combined from the wiring arrangements of multiple first flexible circuit components.

[0016] Furthermore, the steps to determine the correct wire sequence are as follows:

[0017] When the interface at the terminal is a wire interface, the correct wire sequence arrangement can be obtained directly through the wire sequence arrangement at the terminal and the correspondence between the first flexible circuit component and the wire.

[0018] When the interface at the terminal is an FPC / FFC interface, the wiring sequence of the first flexible circuit component is compared with the wiring sequence at the terminal to obtain the wiring sequence conversion sort. The correct wiring sequence of the wires is obtained according to the correspondence between the first flexible circuit component and the wires.

[0019] Furthermore, the FPC / FFC connector is formed by a cover plate and a core to allow for the insertion of gold fingers of the FPC / FFC. On the side of the core near the cover plate, there are multiple terminals arranged in a row at intervals. The terminals are used to connect the wires and the gold fingers.

[0020] Furthermore, the connection method between the first flexible circuit component and the wire is as follows: the gold finger of the first flexible circuit component is inserted into the FPC / FFC connector, so that the gold finger contacts the terminal, and the terminal connects the wire and the gold finger, thereby converting the wiring sequence of the gold finger into the wiring sequence of the wire.

[0021] Furthermore, multiple FPC / FFC connectors can be provided along the line to enable multiple adjustments to the wiring sequence by switching the first flexible circuit assembly and the wires multiple times.

[0022] The beneficial effects of this invention are as follows: This application connects flexible circuit components with traditional wires, realizing the mutual conversion between wire lines and flexible circuit component lines. The wiring sequence of the flexible circuit component connected to the wires can be adjusted by adjusting the wiring sequence at the wire lines. In this way, it can have the function of arbitrarily adjusting the wiring sequence of traditional wires while having the characteristics of high density and lightweight flexible circuit component lines. By controlling the mutual conversion between flexible circuit component / flexible flat cable lines and wire lines, it can adapt to the wiring requirements of different devices.

Detailed Implementation

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terminology used in the specification of this application is for the purpose of describing specific embodiments only and is not intended to limit this application.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings, but this is not intended to limit the scope of the invention.

[0034] Example 1

[0035] like Figure 1-7 As shown, this application provides a method for adjusting the wiring sequence of an FPC / FFC, including the following steps:

[0036] S1. Record the wiring sequence of the first flexible circuit component 100, use FPC / FFC connector 200 to connect the lines of the first flexible circuit component 100 and one end of the wire 2 in a one-to-one correspondence, and mark the wire 2 to record the correspondence between the first flexible circuit component 100 and the wire 2.

[0037] S2. Based on the line sequence arrangement of the first flexible circuit component 100, the correspondence between the first flexible circuit component 100 and the wire 2, and the line sequence arrangement at the terminal, the correct line sequence arrangement of the wire 2 is obtained, and the position of the wire 2 is adjusted according to the correct line sequence arrangement of the wire 2 so that the line sequence arrangement of the wire 2 matches the line sequence arrangement at the terminal.

[0038] In step S1, the first flexible circuit component 100 and the wires 2 are connected and marked in a one-to-one correspondence. Specific wires 2 are selected for different positions of the gold fingers 3 of the first flexible circuit component 100, such as wires 2 of a specific color or wires 2 with a specific number. After recording this mapping relationship, the wire sequence of the flexible circuit component mapped by the wire sequence of the wires 2 can be obtained. In this application, the flexible circuit component is a general term for flat flexible cables and flexible circuit boards, which can specifically cover one or more combinations of flexible flat cables and flexible circuit boards.

[0039] In step S2, the required wiring sequence of the first flexible circuit component 100 can be obtained according to the wiring sequence requirements at the terminal. The terminal can be a device or a transition point. Any connection port that needs to connect the first flexible circuit component 100 can be considered a terminal. Then, based on the wiring sequence of the first flexible circuit component 100 mapped by the wire 2 and the wiring sequence of the first flexible circuit component 100 required at the terminal, the wiring sequence of the first flexible circuit component 100 mapped by the wire 2 is compared and adjusted to the wiring sequence of the first flexible circuit component 100 required at the terminal. The correct wiring sequence of the wire 2 can then be obtained. The wiring sequence of the wire 2 is adjusted according to the correct wiring sequence of the wire 2. After the adjustment is completed, the wiring sequence of the flexible circuit component mapped by the wiring sequence of the wire 2 can meet the wiring sequence requirements at the terminal, which is equivalent to completing the wiring sequence adjustment of the flexible circuit board.

[0040] This method establishes a corresponding marking relationship between the flexible circuit component and the wire 2, and reorganizes the position of the wire 2 based on the wiring sequence requirements of the terminal device. This effectively solves the problem that the flexible circuit component cannot adjust the wiring sequence, has a high degree of customization, can only be used for specific projects, lacks universality, and cannot achieve the cost reduction effect brought about by mass production. This application can realize the random connection of the two ends of the electrical circuit, and the wiring sequence adjustment has high efficiency and accuracy, and can be widely used in consumer electronics, automotive electronics and other fields.

[0041] Specifically, the steps to determine the correct wire sequence for wire 2 are as follows:

[0042] When the interface at the terminal is the wire 2 interface, the correct wire sequence arrangement of the wire 2 can be obtained directly through the wire sequence arrangement at the terminal and the correspondence between the first flexible circuit component 100 and the wire 2.

[0043] When the interface at the terminal is an FPC / FFC interface, the wiring sequence of the first flexible circuit component 100 is compared with the wiring sequence at the terminal to obtain the wiring sequence conversion sort. Based on the correspondence between the first flexible circuit component 100 and the wire 2, the correct wiring sequence of the wire 2 is obtained.

[0044] The correct wiring sequence of wire 2 can be obtained by selecting different methods according to the interface at different terminals. The interface type at the terminal is not limited to the interface types mentioned above. For various types of interfaces, the correct wiring sequence of wire 2 can be obtained by comparing the wiring sequence of the first flexible circuit component 100 and the wiring sequence at the terminal with the required wiring sequence of the first flexible circuit component 100, as well as the correspondence between a flexible circuit component and wire 2.

[0045] Preferably, the FPC / FFC connector 200 includes a connector body 1 and a wire 2 disposed at one end of the connector body 1. The end of the connector body 1 away from the wire 2 is also provided with an FPC / FFC connection port 11. By inserting the first flexible circuit assembly 100 into the FPC / FFC connection port 11, the wiring of the first flexible circuit assembly 100 and the wire 2 can be connected. This method is conducive to quickly adjusting the wiring sequence of the flexible circuit assembly.

[0046] Specifically, the FPC / FFC connector 11 is formed by a cover plate 12 and a core 13 to accommodate the insertion of the gold fingers 3 of the FPC / FFC. On the side of the core 13 near the cover plate 12, there are multiple terminals 14 arranged in a row at intervals. The terminals 14 are used to connect the wires 2 and the gold fingers 3.

[0047] Specifically, the core 13 is provided with a groove 131 for accommodating the terminal 14, and the terminal 14 is fixedly connected to the groove 131. One end of the terminal 14 is provided with an elastic protrusion 141 that protrudes from the surface of the core 13 and is exposed inside the FPC / FFC connector 11. The elastic protrusion 141 abuts against the protrusion of the gold finger 3 to realize the connection between the gold finger 3 and the terminal 14. The other end of the terminal 14 is provided with a conductive part 142 for connecting to the wire 2. The conductive part 142 is set as a non-closed annular structure 1421. The groove 131 is provided through the side facing the wire 2 to expose the conductive part 142 inside the groove 131. The wire 2 and the conductive part 142 are connected by snap-fitting through the annular structure 1421.

[0048] Specifically, the connection method between the first flexible circuit assembly 100 and the wire 2 is as follows: the gold fingers 3 of the first flexible circuit assembly 100 are inserted into the FPC / FFC connector 11, so that the gold fingers 3 contact the terminal 14, and the terminal 14 connects the wire 2 and the gold fingers 3, converting the wiring sequence of the gold fingers 3 to the wiring sequence of the wire 2. This method allows for quick adjustment of the wiring sequence through plugging and unplugging, improving the flexibility and efficiency of assembly. Furthermore, this structure reduces the error rate during installation and ensures a reliable connection between the flexible circuit assembly and the wire 2.

[0049] Example 2

[0050] like Figure 2As shown, the difference between this embodiment and Embodiment 1 is that it further includes step S3:

[0051] S3. Use another FPC / FFC connector 200 to connect the other end of the wire 2 after adjusting the wire sequence to the wires of the second flexible circuit assembly one by one, so that the wires of the second flexible circuit assembly match the wire sequence at the terminal.

[0052] In step S3, after the wires of conductor 2 are adjusted to the correct wiring sequence, the FPC / FFC connector 200 is used to convert conductor 2 back into a flexible circuit assembly. Since the correct wiring sequence of conductor 2 maps to the wiring sequence of the first flexible circuit assembly 100 required at the terminal, after the conductor 2 is converted into a second flexible circuit assembly, the wiring sequence of the second flexible circuit assembly is the wiring sequence of the first flexible circuit assembly 100 required. That is, the wiring of the second flexible circuit assembly matches the wiring sequence at the terminal.

[0053] When it is necessary to adjust the interruption at any position of the flexible circuit component, the interruption adjustment can be performed at any position of the flexible circuit component through the method of this embodiment. The position of the wiring sequence transition can be flexibly adjusted. Moreover, when the interface at the terminal is an FPC / FFC interface, choosing the method of this embodiment is beneficial to the matching of the flexible circuit component and the FPC / FFC interface.

[0054] Example 3

[0055] like Figure 2 As shown, the difference between this embodiment and Embodiment 1 is that, in step S1, the number of first flexible circuit components 100 is at least 2, and the number of FPC / FFC connectors 200 is set to correspond to the number of first flexible circuit components 100; or, in step S1, the number of FPC / FFC connectors 200 FPC / FFC connection ports 11 is at least 2, and the number of FPC / FFC connectors 200 FPC / FFC connection ports 11 is set to correspond to the number of first flexible circuit components 100; and both the number of FPC / FFC connectors 200 and the number of FPC / FFC connectors 200 FPC / FFC connection ports 11 are set to multiple.

[0056] This configuration allows multiple flexible circuit components to be connected at the FPC / FFC connector 200, enabling simultaneous adjustment of the wiring sequence of multiple flexible circuit components, thus enhancing system flexibility. It is particularly suitable for application scenarios requiring large-scale adjustments to the wiring sequence.

[0057] Preferably, the wiring sequence at the terminal can be freely combined from the wiring sequence of multiple first flexible circuit components 100. When the wiring sequence of multiple flexible circuit components is adjusted, the positions of the wires 2 mapped by different flexible circuit components can be exchanged, so that the wires 2 can simultaneously map the wiring sequence of different flexible circuit components. This satisfies the requirement for the wiring sequence of multiple flexible circuit components after arrangement and combination at the terminal, and solves the problem that existing flexible circuit components cannot adjust the wiring sequence between different flexible circuit components.

[0058] Example 4

[0059] The difference between this embodiment and Embodiment 1 is that: in this embodiment, multiple FPC / FFC connectors 200 can be set along the line for multiple switching of the first flexible circuit component 100 and the wire 2 to achieve multiple adjustments to the wiring sequence. When multiple terminals are set along the line, the wiring sequence needs to be adjusted when passing through multiple terminals. This application uses multiple FPC / FFC connectors 200, allowing the system to flexibly adjust the wiring sequence at each terminal to meet the needs of different terminals. Furthermore, the FPC / FFC connectors 200 can remove redundant wiring, reducing space occupation. The above description illustrates and describes several preferred embodiments of the present invention. However, as mentioned above, it should be understood that the present invention is not limited to the forms disclosed herein and should not be considered as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be modified within the scope of the inventive concept described herein through the above teachings or related field techniques or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
