Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to an FPC connector. Background Technology

[0002] Connectors are components frequently encountered by electronic engineers. Their function is to bridge gaps in circuits or between isolated circuits, allowing current to flow and enabling the circuit to perform its intended function. Connectors are indispensable components in electronic devices; following the path of current flow, you will always find one or more connectors. Connector forms and structures are highly diverse, varying depending on the application, frequency, power, and operating environment.

[0003] However, in the current assembly and production of FPC connectors and FPC cables, the connector of the FPC cable is inserted into the base of the FPC connector to form a connection between the FPC cable and the terminal block inside the FPC connector. At the same time, the connector of the FPC cable and the claw of the FPC connector are locked together. The connector of the FPC cable and the claw of the FPC connector need to be fully aligned to achieve the locking effect. However, in actual production, whether the connector of the FPC cable is inserted automatically or manually, there are always cases where the insertion is not complete. This results in the connector of the FPC cable and the FPC connector not being locked together. The connection is only temporarily maintained by the friction after insertion. Once external force is applied, it is easy to detach, resulting in an insufficiently firm connection. Summary of the Invention

[0004] The purpose of this utility model is to provide an FPC connector to solve the problem mentioned in the background art. In the assembly and production of existing FPC connectors and FPC cables, the connector of the FPC cable is inserted into the base of the FPC connector to form a connection between the FPC cable and the terminal block inside the FPC connector. At the same time, the connector of the FPC cable and the hook of the FPC connector are locked together. The connector of the FPC cable and the hook of the FPC connector need to be fully aligned to achieve the locking effect. However, in actual production, whether the connector of the FPC cable is inserted automatically or manually, there is always a situation where the insertion is incomplete. This results in the connector of the FPC cable and the FPC connector not being locked together. The connection is only temporarily maintained by the friction after insertion. Once an external force is applied, it is easy to detach, resulting in an insufficiently firm connection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an FPC connector, comprising a connector body and an FPC cable, wherein the connector body and the FPC cable are plugged into each other; the connector body includes a base and a cover plate that flips over above the base; fixing blocks are fixedly connected to both sides of the top surface of the base; the cover plate is rotatably connected between the two fixing blocks; mounting cavities are formed on both sides of the rear surface of the base; locking components are installed in the mounting cavities, and the top surface of the locking components abuts against the bottom surface of the cover plate; and mounting cavities are formed on both sides of the surface of the FPC cable.

[0025] like Figure 1-7This is a schematic diagram of the structure of an FPC connector according to a preferred embodiment of the present invention. In this embodiment, an FPC connector includes a connector body 6 and an FPC cable 2. The connector body 6 and the FPC cable 2 are connected by a mating connection. The connector body 6 includes a base 1 and a cover plate 4 that flips over above the base 1. Fixing blocks 3 are fixedly connected to both sides of the top surface of the base 1. The cover plate 4 is rotatably connected between the two fixing blocks 3. The rear surface of the base 1 has two mounting cavities 14. A locking component 5 is installed in the mounting cavity 14, and the top surface of the locking component 5 abuts against the bottom surface of the cover plate 4. Locking ports 21 are opened on both sides of the surface of the FPC cable 2. The locking component 5 is movably connected in the locking ports 21. In combination with the structural design of the present invention, by setting the locking component 5, the connecting end of the FPC cable 2 is pushed deeper into the cable slot 12, so that the locking block 54 is locked into the locking port 21, thereby forming an interlocking phenomenon, which effectively improves the stability of the FPC cable 2 connector and the FPC connector after assembly.

[0026] In this embodiment, connecting plates 41 are fixedly connected to both sides of the outer wall of the cover plate 4. The outer walls of the connecting plates 41 are connected to the fixed blocks 3 through rotating columns 42 to realize the flipping function of the cover plate 4. A protrusion 43 is fixedly connected to the bottom of the connecting plates 41. With this structural design, the protrusion 43 is displaced and squeezes the abutment block 53 when the cover plate 4 is flipped.

[0027] In this embodiment, the locking assembly 5 includes a locking piece 51, an elastic connecting piece 52, a locking block 54, and an abutment block 53. One end of the locking piece 51 is fixedly connected to the elastic connecting piece 52, and one side of the elastic connecting piece 52 is fixedly connected to the locking block 54. The locking block 54 is engaged in the locking port 21, thereby realizing the connection and fixation between the FPC cable 2 and the connector body 6. One end of the elastic connecting piece 52 is fixedly connected to the abutment block 53, and the top of the abutment block 53 abuts against the bottom of the protrusion 43.

[0028] In this embodiment, the locking piece 51 has an avoidance opening 55 directly below the contact block 53 on its surface. This effectively prevents the locking piece 51 from interfering with the downward displacement of the contact block 53 when the cover plate 4 is opened and the protrusion 43 presses the contact block 53 downward. This would prevent the locking block 54 from disengaging from the locking opening 21, thus preventing the FPC cable 2 from separating from the connector body 6.

[0029] In this embodiment, the elastic connecting piece 52 adopts a U-shaped structure design. Its structure design can improve the elasticity of the elastic connecting piece 52, which can be reused repeatedly. When the cover plate 4 is closed, the elastic connecting piece 52 can return to its original shape.

[0030] In this embodiment, a wiring cavity 11 is provided on the top surface of the base 1. A plurality of ribbon cable slots 12 are evenly provided in the wiring cavity 11. A wiring terminal 13 is installed in the ribbon cable slot 12. The signal is conducted by the wiring terminal 13 contacting the contact piece on the surface of the FPC ribbon cable 2.

[0031] Working principle

[0032] Specifically, during assembly, the connecting end of the FPC cable 2 is pushed deeper into the cable slot 12, causing the locking block 54 to engage in the locking port 21, thus creating an interlocking phenomenon and fixing the FPC cable 2 to the connector body 1. For disassembly, the cover plate 4 needs to be opened. Since the protrusion 43 abuts against the contact block 53, when the cover plate 4 rotates, the protrusion 43 pushes the contact block 43 downwards, causing the elastic connecting piece 52 to deform and displace downwards. At this time, the locking block 54 in the locking port 21 also displaces downwards along with the elastic connecting piece 52, causing the locking block 54 to disengage from the locking port 21. Then, the FPC cable 2 is pulled out of the connector body 1, thus completing the separation of the FPC cable 2 from the connector body 1.

[0033] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
