Abstract
Description
Technical Field
[0001] This utility model relates to the field of FPC connector technology, and in particular to a front-insertion, rear-flip-type FPC connector. Background Technology
[0002] FPC / FFC connectors are flexible circuit board / ribbon cable connectors widely used in various civilian mobile communication devices and personal terminal devices. Their function is to enable signal connection or transmission between internal functional modules or with external devices, as well as to connect the device to a power supply or signal source, ultimately achieving a power / signal connection solution. Existing FPC connector backstops are structurally unstable, and the back cover needs to be secured to the main body via a snap-fit mechanism during opening and closing, which is not only inconvenient but also increases the manufacturing difficulty of the FPC connector. Therefore, we propose a front-insertion, rear-flip-cover type FPC connector. Utility Model Content
[0003] To address the aforementioned problems, this invention provides a front-insertion, rear-flip-cover FPC connector. This invention solves the problems of existing FPC connector backstops, which suffer from insufficient overall structural stability and require the rear cover to be secured to the main body via a snap-fit mechanism during opening and closing, making opening and closing inconvenient and increasing the manufacturing difficulty of the FPC connector.
[0004] This utility model discloses a front-plug, rear-flip-type FPC connector, including a PCB base plate. A connector housing is provided on the top of the PCB base plate. The connector housing has multiple equally spaced terminal slots in the middle. Terminals are inserted into the terminal slots. Grounding plate clearance grooves are provided on both sides of the connector housing. A grounding plate slot is provided on one side of the grounding plate clearance groove of the connector housing. A grounding plate is inserted into the grounding plate slot. A rear cover is provided on one side of the upper end of the connector housing. A terminal limiting pivot matching the terminal is provided on the side of the rear cover near the connector housing.
[0005] In the above scheme, the terminal block includes a first conductor, a second conductor is provided above the middle of the first conductor, a third conductor is fixedly connected above the second conductor, a ribbon cable contact is provided on the inner end of the first conductor and the third conductor away from the back cover, and a rotating shaft groove matching the terminal limiting rotating shaft is provided on the inner side of the first conductor and the third conductor away from the ribbon cable contact.
[0006] In the above scheme, the first conductor is provided with a card block above the second conductor on the side away from the rotating shaft slot, and the connector housing is provided with a card slot that matches the card block.
[0007] In the above scheme, a terminal welding plate is provided below the first conductor on the side near the rotating shaft slot, and a terminal welding point matching the terminal welding plate is provided on the PCB base plate.
[0008] In the above scheme, a grounding plate welding piece is provided below one end of the grounding plate near the grounding plate avoidance groove, and a grounding plate welding point matching the grounding plate welding piece is provided on the PCB base plate.
[0009] In the above scheme, a limiting block is provided below the grounding plate on the side near the grounding plate welding plate, and a limiting groove matching the limiting block is provided in the grounding plate slot.
[0010] The advantages and beneficial effects of this utility model are as follows: This utility model provides a front-insertion, rear-flip-cover FPC connector. The cooperation between the locking block and the locking slot allows the wiring terminals to be stably installed inside the wiring terminal slot. The cooperation between the limiting groove and the limiting block allows the grounding piece to be stably fixed inside the grounding piece slot. The cooperation between the rotating shaft slot and the terminal limiting rotating shaft allows the rear cover to rotate via the terminal limiting rotating shaft. After the rear cover is closed, the clamping of the terminal limiting rotating shaft by the rotating shaft slot ensures that the rear cover is stably fixed above the connector housing. This type of FPC connector has a simple structure, good installation stability, and the rear cover is easy to open and close. The rear cover can be positioned via the wiring terminals, reducing the manufacturing difficulty of FPC connectors while effectively improving their production efficiency. Attached Figure Description
