[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0024] This application proposes a FPC100 with a reinforced neck, see Figure 1 and Figure 2, including: this board 10 and several metal pins 11. The metal pins 11 are conductive and electrically connected to the circuits inside the FPC, and are directly plugged into other components to be electrically connected to other components. The board 10 is provided with a plug-in end 12 and two notches 13. The plug-in end 12 is arranged at the top of the board 10, and the plug-in end 12 and the two notches 13 are arranged at the edge of the board 10. The two notches 13 are arranged on the adjacent sides of the plug-in end 12. Several metal pins 11 are arranged on the plug-in end 12 of the board 10. The left and right outermost metal pins 11 extend reinforcement parts 14 toward the nearest notch 13 at one end close to the notch 13. The metal pins 11 are metal and have high hardness. They can reinforce the notch 13, increase the hardness of the FPC 100 with a reinforced neck at the notch 13, prevent the FPC 100 with a reinforced neck from breaking or cracking at the notch 13, and extend the service life of the FPC 100 with a reinforced neck. Preferably, the two notches 13 are symmetrically arranged.

[0025] The metal pin 11 is made of copper, which has good electrical conductivity. The FPC transmits electrical signals to components connected to the metal pin 11 through the metal pin 11, thereby reducing energy consumption.

[0026] In one embodiment, see Figure 1 , the metal pins 11 are arranged in parallel, so that the conductivity of the FPC and other components is better. When the plug-in end 12 is plugged into the component to be connected, the metal pins 11 are not connected to each other, and the metal pins 11 are electrically connected to the pins of the component to be connected one by one, thereby improving the accuracy of the electrical connection. Furthermore, the metal pins 11 are arranged on the board 10 at equal intervals, so that the metal pins 11 are compactly arranged in the board 10, and the good connection of the metal pins 11 is ensured.

[0027] In addition, the thickness of the reinforcing portion 14 is greater than the thickness of the metal pin 11 , so the hardness of the reinforcing portion 14 is greater, further improving the anti-bending capability of the FPC.

[0028] In another embodiment, a component area is provided on one side of the board 10, and components are welded on the component area. A circuit with specific functions is formed between the components according to a specific connection relationship, and the function can be realized by software. Furthermore, since the board 10 is the bottom plate of the FPC, it is soft and easy to bend, a reinforcing sheet is provided on the opposite side of the board 10 to the component area. The reinforcing sheet provides support for the component area to prevent the board 10 from bending and affecting the placement of other components.

[0029] In addition, an exposed copper layer is provided on the board 10, and the exposed copper layer is used for grounding, reducing interference, or making a quick electrical connection with other components to improve efficiency and reliability of electrical connection.

[0030] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
