Description

Technical Field

[0001] This utility model relates to the field of ribbon cable technology, specifically to an FFC flexible ribbon cable with positioning holes that prevents misalignment during insertion and removal. Background Technology

[0002] FFC (Flexible Flat Cable) is a flexible circuit connector consisting of parallel-arranged flat conductors (usually copper wires) and an insulating film (such as polyester PET or polyimide PI). Its structure is similar to a "ribbon flat cable," with the conductors fixed between the insulating layers through a pressing process to form a bendable flat ribbon shape.

[0003] Traditional FFC flat cables rely on the interference fit between the thickness of the cable's connector and the gap of the connector to achieve connection. However, there are no locking clips between the FFC flat cable and the connector. The connection method is simple and direct, but it may lack sufficient stability. In addition, some FFC flat cables lack anti-misalignment mechanisms when the pins are plugged in. When manually connecting them, misalignment is likely to occur, affecting the connection efficiency.

[0023] In the description of this utility model, it should be understood that the terms "center," "lateral," "upper," "lower," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof are intended to cover non-exclusive inclusion.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] For ease of connection, please refer to the attached document. Figure 1 and attached Figure 2 An FFC flexible flat cable with positioning holes to prevent misalignment during insertion and removal includes a cable body 1, and further includes: a first connector 2 and a second connector 3; pairs of first connectors 2 are respectively disposed on both sides of the cable body 1, and two second connectors 3 are respectively inserted into the first connectors 2 on both sides; one side of the first connector 2 is provided with a plug 4, and one side of the second connector 3 is provided with a slot 5 for use with the plug 4; a warning sign is provided at the top of the second connector 3. When the first connector 2 and the second connector 3 are inserted into one piece, the plug 4 is inserted into the slot 5, achieving a complete connection, and the warning sign can indicate the upward-facing side for easy direct insertion.

[0026] To further enhance the overall connection stability between the first connector 2 and the second connector 3, combined with the attached... Figure 3 Appendix Figure 4 and attached Figure 5A locking structure is provided between the first connecting member 2 and the second connecting member 3. The locking structure includes locking blocks 9 and insertion blocks 15. Four locking blocks 9 are respectively disposed at the top and bottom ends of the first connecting members 2 on both sides. Each locking block 9 is provided with a through hole 10. The top and bottom ends of the second connecting member 3 are provided with connecting plates 14. Several insertion blocks 15 are respectively disposed on one side of the connecting plates 14 and are used to cooperate with the through holes 10. The locking structure also includes limiting posts 11 and springs 12. Several limiting posts 11 are respectively inserted into the locking blocks 9 and extend into the through holes 10. One end of each limiting post 11 is provided with a circular piece 13. Several springs 12 are sleeved on the limiting posts 11 and are located between the circular piece 13 and the locking blocks 9. Each insertion block 15 is provided with a limiting hole 16 for cooperation with the limiting post 11. One side of each insertion block 15 is a ramp structure. When the first connector 2 and the second connector 3 are inserted together, the insertion block 15 is inserted into the through hole 10. Since one side of the insertion block 15 is a sloping structure, it continuously pushes up the limiting post 11, and the spring 12 is continuously stretched. As the insertion block 15 moves continuously, the limiting post 11 enters the limiting hole 16, and the spring 12 rebounds, so that the limiting post 11 is stably inserted into the limiting hole 16, locking and fixing the first connector 2 and the second connector 3, resulting in high overall stability.

[0027] To prevent misalignment, in conjunction with the attached... Figure 3 The first connector 2 has positioning holes 7 and positioning posts 8 on both sides. Positioning blocks 6 are provided on both sides of the first connector 2, and positioning holes 7 are respectively provided on the positioning blocks 6. Pairs of positioning posts 8 are respectively provided on both sides of the second connector 3 and are used in conjunction with the positioning holes 7. The cross-sections of the positioning holes 7 and the positioning posts 8 are trapezoidal. When connecting the first connector 2 and the second connector 3, the positioning posts 8 are preferentially inserted into the positioning holes 7. Since the cross-sections of the positioning holes 7 and the positioning posts 8 are trapezoidal, they can guide the connection during insertion, preventing misalignment and displacement.

[0028] In specific implementation of this utility model:

[0029] First, bring the first connector 2 and the second connector 3 closer together. The sign will indicate the upward side, making it easier to correctly insert the second connector 3 into the first connector 2.

[0030] At this time, the positioning pin 8 is inserted into the positioning hole 7 first. Since the cross-sections of the positioning hole 7 and the positioning pin 8 are both trapezoidal structures, they can be guided during insertion to prevent misalignment and avoid displacement.

[0031] Next, the second connector 3 is brought closer to the first connector 2, and the plug 4 is inserted into the slot 5 to achieve a complete connection. At the same time, the insertion block 15 is inserted into the through hole 10. Since one side of the insertion block 15 is a sloping structure, it continuously pushes up the limiting post 11, and the spring 12 is continuously stretched. As the insertion block 15 moves, the limiting post 11 enters the limiting hole 16, and the spring 12 rebounds, so that the limiting post 11 is stably inserted into the limiting hole 16, locking and fixing the first connector 2 and the second connector 3, resulting in high overall stability.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
