Abstract
Description
Technical Field
[0001] This utility model relates to the field of connector technology, and more specifically, to an FPC / FFC connector. Background Technology
[0002] Flexible printed circuit boards (FPCs) and flexible flat cables (FFCs) have seen further applications in signal loops in the automotive, industrial, and consumer electronics industries. However, the widespread application of FPCs / FFCs in the energy storage battery and automotive industries still faces some obstacles. This is mainly because the loop arrangement of FPCs / FFCs is in a two-dimensional plane, unlike traditional wire harnesses which are spatial and three-dimensional 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 an FPC / FFC connector. Utility Model Content
[0005] One of the objectives of this utility model is to provide an FPC / FFC connector that addresses the shortcomings of existing technologies. This connector enables the connection between FPC / FFC and traditional wires, allowing for the combination of the advantages of both FPC / FFC and traditional wires when setting up wiring. It can meet the requirements of high density and lightweight design while also allowing for free adjustment of wiring sequence.
[0006] To solve the above-mentioned technical problems, this application adopts the following technical solution:
[0007] An FPC / FFC connector is provided, including 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. The FPC / FFC connection port is formed by a cover plate and a core to allow insertion of gold fingers of FPC / FFC. A plurality of terminals are disposed in a row at intervals on the side of the core near the cover plate. The terminals are used to connect the wire and the gold fingers.
[0008] Furthermore, the number of FPC / FFC connection ports is at least one, and the terminals are provided at the positions corresponding to the FPC / FFC connection ports.
[0009] Furthermore, one or more connector bodies are provided at the same end of the wire.
[0010] Furthermore, the connector body is provided at both ends of the wire.
[0011] Furthermore, the core is provided with a groove for accommodating the terminal, and the terminal is fixedly connected to the groove. One end of the terminal is provided with an elastic protrusion that protrudes from the surface of the core and extends into the FPC / FFC connector. The elastic protrusion abuts against the protrusion of the gold finger to achieve the connection between the gold finger and the terminal. The other end of the terminal is provided with a conductive part for connecting to a wire.
[0012] Furthermore, the conductive part is configured as a non-closed annular structure, and the groove is provided through one side facing the wire to expose the conductive part in the groove. The wire and the conductive part are connected by snap-fitting through the annular structure.
[0013] Furthermore, multiple ring structures can be provided along the connection direction of the conductive part and the wire, and the wire is sequentially snapped into connection with the multiple ring structures.
[0014] Furthermore, the elastic protrusion is configured as two protrusions with a certain distance between them, and a snap-fit beam is provided in the middle of the groove. The snap-fit beam is disposed between the two protrusions to realize the snap-fit between the terminal and the groove.
[0015] Furthermore, the terminal also includes a main body portion connecting the conductive portion and the elastic protrusion. Each part of the main body portion is provided with an elastic portion near the groove, and the elastic portion abuts against the wall of the groove. A second elastic portion is provided at the connection between the elastic protrusion and the main body portion.
[0016] Furthermore, the cover plate is U-shaped, and there are two cover plates. The two cover plates enclose a cavity, which can be used to accommodate the rubber core.
[0017] The protrusions of the gold fingers (3), the number of terminals (14), and the number of wires (2) are set in a one-to-one correspondence.
[0018] The beneficial effects of this utility model are as follows: This application, by providing a connector body, can connect the gold fingers of FPC / FFC to traditional wires, converting FPC / FFC lines into traditional wire lines, and vice versa. This allows the application to simultaneously possess the advantages of both FPC / FFC and traditional wires when setting up the circuit. When it is necessary to adjust the wiring sequence of the FPC / FFC circuit, the FPC / FFC circuit can be converted into a traditional wire line for the adjustment. After adjustment, when it is necessary to save space to meet the requirements of high density and lightweight, the traditional wire line can be converted back into the FPC / FFC circuit. This application, through the setting of the connector body, combines the use of traditional wires and FPC / FFC circuits, making the circuit setting of this application more flexible, and different circuits can be combined and used according to different needs.

[0030] Example 1
[0031] like Figure 1-5 As shown, this application provides an FPC / FFC connector, including 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. The wire 2 and the FPC / FFC can be connected by being inserted into the connector body 1. The FPC / FFC connection port 11 is formed by a pressure plate 12 and a core 13 to allow the insertion of gold fingers 3 of the FPC / FFC. On the side of the core 13 near the pressure plate 12, a plurality of terminals 14 are arranged in a row at intervals, and the arrangement direction of the terminals 14 is along the protrusion of the gold fingers 3. When the gold fingers 3 are inserted into the FPC / FFC connection port 11, the gold fingers 3 and the terminals 14 abut against each other, and the terminals 14 are used to connect the wire 2 and the gold fingers 3.
[0032] With this configuration, when two devices are respectively set as wire 2 port and FPC / FFC port, and it is necessary to connect FPC / FFC to wire 2 port, the FPC / FFC line can be converted into wire 2 line through connector body 1 and then connected to wire 2 port in this embodiment. This application can realize the connection between different types of line ports through the configuration of connector body 1, and the wiring sequence can be adjusted through wire 2 end to meet the different wiring sequence requirements of different devices.
[0033] Preferably, terminal 14 is fixedly connected to groove 131. One end of terminal 14 is provided with elastic protrusion 141, which protrudes from the surface of core 13 and is exposed inside FPC / FFC connector 11. When gold finger 3 is inserted into FPC / FFC connector 11, elastic protrusion 141 is compressed and abuts against the protrusion of gold finger 3, achieving good contact between gold finger 3 and terminal 14 for connection. The other end of terminal 14 is provided with conductive part 142 for connection with wire 2. The elastic protrusion 141 of terminal 14 enables quick connection between gold finger 3 and FPC / FFC connector, while the conductive part 142 of the other end of terminal 14 can connect wire 2 to terminal 14. Through the configuration of terminal 14, the current of different protrusions in gold finger 3 can be transmitted to different wires 2, and the wiring sequence can be adjusted by adjusting the position of wire 2 to meet the wiring sequence requirements of different devices.
[0034] Preferably, the conductive part 142 is configured as a non-closed annular structure 1421, and the groove 131 is provided through the side facing the wire 2, so that the conductive part 142 is exposed in the groove 131, allowing the wire 2 to directly extend into the groove 131 and connect with the conductive part 142. The wire 2 and the conductive part 142 are connected by snap-fitting through the annular structure 1421. The snap-fitting connection between the wire 2 and the conductive part 142 by wrapping the wire 2 with the annular structure 1421 is beneficial to the stable connection between the wire 2 and the terminal 14.
[0035] Preferably, multiple ring structures 1421 can be provided along the connection direction between the conductor 142 and the wire 2. The wire 2 is sequentially snapped into the multiple ring structures 1421. The provision of multiple ring structures 1421 provides multiple points of connection between the wire 2 and the terminal 14, further improving the stability of the wire 2.
[0036] Preferably, the elastic protrusion 141 is configured as two protrusions with a certain distance between them, and a snap-fit beam 132 is provided in the middle of the groove 131. The snap-fit beam 132 is provided between the two protrusions to realize the snap-fit between the terminal 14 and the groove 131, so that the terminal 14 is stably set in the groove 131 to prevent the terminal 14 from being displaced or falling off during the insertion and removal of the gold finger 3.
[0037] Preferably, the terminal 14 further includes a main body 145 connecting the conductive part 142 and the elastic protrusion 141. Each part of the main body 145 near the groove 131 is provided with an elastic part 143, and the elastic part 143 abuts against the wall of the groove 131. A second elastic part 144 is provided at the connection between the elastic protrusion 141 and the main body 145. This arrangement achieves a stable connection between the terminal 14 and the groove 131. Each wall of the terminal 14 and the groove 131 has a buffer. When the connector body 1 is impacted, the elastic part 143 and the second elastic part 144 will absorb part of the impact force, preventing excessive force from being directly transmitted between the wire 2 and the terminal 14.
[0038] Preferably, the pressure plate 12 is U-shaped, and there are two pressure plates 12. The two pressure plates 12 enclose a cavity to accommodate the core 13. This arrangement allows the pressure plate 12 to function as both the outer shell of the connector body 1 and the FPC / FFC connection port 11. This makes disassembling the connector body 1 simple and replacing the terminals 14 even simpler. The terminals 14 can be quickly replaced simply by removing the two pressure plates 12, which facilitates the maintenance and repair of the terminals 14. Furthermore, the protrusions of the gold fingers 3, the number of terminals 14, and the number of wires 2 are all set in a one-to-one correspondence. This method is conducive to the accurate correspondence between the signals of the FPC / FFC and the signals at the wires, ensuring a stable and reliable connection.
[0039] Preferably, the number of FPC / FFC connection ports 11 is at least one, and the terminal 14 is provided at the position corresponding to each of the FPC / FFC connection ports 11. With this arrangement, multiple FPC / FFCs can be connected on one connector body 1, and wires 2 can be led out from multiple FPC / FFC lines. Then, different wires 2 can be connected to the interface of the device as needed. With these arrangements, different FPC / FFC lines can be combined and connected.
[0040] Example 2
[0041] like Figure 3 As shown, unlike embodiment 1, one or more connector bodies 1 are provided at the same end of the wire 2. Multiple connector bodies 1 can also connect multiple gold fingers 3. After connecting the gold fingers 3, the wire 2 can be led out. It can also realize the arrangement and combination of wires 2 of different FPCs / FFCs, and solve the problem of disordered connection of the two ends of the electrical circuit.
[0042] Example 3
[0043] like Figure 3As shown, unlike Embodiment 1, connector bodies 1 are provided at both ends of the wire 2. The FPC / FFC is converted into the wire 2 at the first connector body 1, and the wiring sequence is adjusted at the wire 2. Then, the wire 2 with the adjusted wiring sequence is converted into FPC / FFC through the second connector body 1 to realize the wiring sequence adjustment of FPC / FFC. When multiple connector bodies 1 are provided at both ends of the wire 2, the wiring sequence of multiple FPC / FFCs at one end of the wire 2 can be adjusted by adjusting the wiring sequence of the wire 2, including the wiring sequence of the same FPC / FFC and the wiring sequence between different FPC / FFCs.

However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the present invention's conception through the foregoing teachings or related technical or knowledge.
