Referring to fig. 2, further, the flexible printed circuit 1 includes a main body 11, a connecting portion 12 connected to the main body 11, and a gold finger 13 connected to the connecting portion 12, wherein two reinforcing pieces 14 are disposed on outer surfaces of two sides of the connecting portion 12 and are staggered from each other. In the conventional design of the flexible printed circuit 1, the reinforcing sheets 14 are usually not provided or the reinforcing sheets 14 are provided at the same position and the widths of the reinforcing sheets 14 are the same, so that when the flexible printed circuit 1 is pulled out, the applied pressure is concentrated on the same straight line, which results in slight circuit breakage of the flexible printed circuit 1. The utility model provides a flexible printed circuit 1 is because two reinforcement pieces 14 are located the both sides of connecting portion 12 respectively and stagger the setting each other, and when extracting flexible printed circuit 1, both sides reinforcement piece 14 gives flexible printed circuit 1's pressure and not on same line segment, and stress can not concentrate on same straight line when buckling yet, avoids stress concentration from this, and the problem of the easy slight outage of circuit of golden finger 13 department improves the product yield.
Furthermore, the two reinforcing pieces 14 staggered with each other in the present invention can be respectively disposed at two different positions; the positions of the central points may be the same, but the widths of the two reinforcing sheets 14 are different, and the stress generated when the two reinforcing sheets 14 are bent is not concentrated on the same straight line, so that the problems that the stress is concentrated and the circuit at the golden finger 13 is easily broken slightly can be avoided, and the product yield is improved. In this embodiment, the reinforcing pieces 14 include a first reinforcing piece and a second reinforcing piece, each reinforcing piece 14 has a different width, and the center points of the reinforcing pieces 14 are located on the same horizontal line, so that the edges of the reinforcing pieces 14 are staggered from each other and are not concentrated on the same straight line.
Further, the material of the reinforcing sheet 14 is FR4, PI or stainless steel, and in other embodiments, if the heat generation amount of the flexible printed circuit board 1 is large, a heat dissipation material with better heat dissipation effect, such as an aluminum foil reinforcing sheet 14, may also be used.
Furthermore, the outer surface of the reinforcing sheet 14 is provided with a diamond knurl, so that the flexible printed circuit board 1 can be pulled out more easily when being pulled out, and the risk of circuit fracture of the flexible printed circuit board 1 is reduced.
