Technical Field

[0001] The utility model relates to the technical field of flexible printed circuit boards, and specifically relates to a plug-in type flexible printed circuit board. Background Art

[0002] A flexible printed circuit board, also known as a "flexible board", is a printed circuit made of a flexible insulating substrate. The flexible circuit provides excellent electrical performance, can meet the design requirements of smaller and higher density installations, and also helps to reduce the assembly process and enhance reliability. The flexible printed circuit board is the only solution to meet the miniaturization and mobility requirements of electronic products. It can be freely bent, wound, and folded, can withstand millions of dynamic bends without damaging the wires, can be arranged arbitrarily according to the spatial layout requirements, and can move and stretch arbitrarily in three-dimensional space, so as to achieve the integration of component assembly and wire connection; the flexible printed circuit board can greatly reduce the volume and weight of electronic products, and is suitable for the development needs of electronic products towards high density, miniaturization, and high reliability.

[0003] A plug-in type flexible printed circuit board proposed according to the publication number: CN219123598U includes a main body. Sealing blocks are arranged on both sides of the first flexible printed circuit board. Connecting heads are arranged on both sides of the sealing blocks. A connector mechanism is connected to one side of the connecting head. An anti-slip block mechanism is arranged inside the connector mechanism. A gold finger is arranged at the top of the connecting head. An elastic conductive sheet connection structure is arranged at the bottom of the connecting head. A connector fixing structure is arranged at the top of the connector mechanism. In this plug-in type flexible printed circuit board, by setting the sealing block, slider, anti-slip thread, connecting plate, block, and first spring, when pushing the slider, the anti-slip thread can increase the friction force, making it easier to push the slider and avoid slipping. By pushing the slider, the connecting plate and the block are driven to move. By moving the block to the rear end of the connecting head, the block can be restricted from falling off. When the sealing block is inserted into the connector mechanism, the purpose of dust and water prevention can be achieved.

[0022] The present invention provides a plug-in type flexible printed circuit board as Figures 1 to 4 shown, which includes a connection mechanism 1 and flexible printed circuit board bodies 2 inserted on both sides of the connection mechanism 1. A pressing component 3 is arranged in the inner cavity of the connection mechanism 1.

Plugging mechanisms 4 are arranged on both sides of the connection mechanism 1 corresponding to the flexible printed circuit board bodies 2. By arranging the connection mechanism 1, the positions where the flexible printed circuit board bodies 2 are plugged can be connected, facilitating the plugging of the flexible printed circuit board bodies 2. Subsequently, through the arranged plugging mechanisms 4, the plugged flexible printed circuit board bodies 2 are positioned again, enhancing the firmness of the plugging of the flexible printed circuit board bodies 2 and making it not easy to fall off.

[0023] The connection mechanism 1 includes a protective shell 11. A plurality of through slots 12 are opened on both side walls of the protective shell 11. A bottom plate 13 is fixedly connected to the center of the bottom of the inner cavity of the protective shell 11.

The plug-in head of the flexible printed circuit board body 2 penetrates through the through slots 12 and is located on the side where the pressing component 3 and the bottom plate 13 face each other and fit.

[0024] The pressing component 3 includes a connecting rod 31. The surface of the connecting rod 31 is slidably connected in the inner cavity of the sleeve 14. The bottom end of the connecting rod 31 is fixedly connected with a pressing plate 32 that cooperates with the bottom plate 13. The plug-in head of the flexible printed circuit board body 2 penetrates through the through slots 12 and is located on the side where the pressing plate 32 and the bottom plate 13 face each other and fit. A first spring 33 is sleeved on the connecting rod 31. One end of the first spring 33 is fixed on the inner wall of the protective shell 11, and the other end of the first spring 33 is fixed on the upper surface of the pressing plate 32. By arranging the first spring 33 to provide an elastic effect, the pressing plate 32 on the connecting rod 31 is driven to perform telescopic operation in cooperation with the sleeve 14. Subsequently, through the fitting between the pressing plate 32 and the bottom plate 13, the plug-in head of the plugged flexible printed circuit board body 2 can be pre-positioned, and then it is convenient for the plugging mechanism 4 to perform plugging and positioning on the flexible printed circuit board body 2.

[0025] The plugging mechanism 4 includes a positioning rod 41 and a plugging rod 42. Activity grooves 43 are provided at corresponding positions on both sides of the top of the protective shell 11 corresponding to the sliding sleeves 14. One end of the plugging rod 42 is plugged into the inner cavity of the protective shell 11 through the activity groove 43.

[0028] A limiting block 6 is fixedly connected to the top of the connecting rod 31. The cross-sectional area of the limiting block 6 is larger than the cross-sectional area of the sliding sleeve 14, which can provide a limiting effect on the connecting rod 31.

[0029] During specific use, first, the staff member drives the insertion rod 42 on the positioning plate 451 to move upward through the handle 5. Then, the flexible circuit board body 2 to be inserted is inserted into the protective shell 11 through the insertion joint passing through the through slot 12. With the elastic action provided by the first spring 33, the pressing plate 32 on the connecting rod 31 can perform telescopic operation in cooperation with the sliding sleeve 14. Subsequently, through the fitting between the pressing plate 32 and the bottom plate 13, the insertion joint of the inserted flexible circuit board body 2 can be pre-positioned. Then, the staff member releases the pulling force on the handle 5, and then, with the elastic rebound provided by the second spring 452, the insertion rod 42 on the positioning plate 451 moves downward, driving the positioning rod 41 to dock with the slot 44 opened on the flexible circuit board body 2, facilitating the position fixation of the flexible circuit board body 2 and enhancing the stability of the insertion of the flexible circuit board body 2.
