[0002] Flexible printed circuit (FPC, Flexible Printed Circuit) is a commonly used electrical connection device in various mobile terminals. One end is designed with a gold finger for connecting with the connector. In order to reduce the width of the flexible printed circuit, the gold finger is designed as two The first row of gold fingers closer to the end of the flexible circuit board needs to pass through the gap between the second row of gold fingers. In order to ensure a safe distance, the first row of gold fingers leads to the second row of gold fingers. The distance between the gold fingers is large, which increases the width of the flexible circuit board, which is not conducive to the miniaturization of the device

The invention discloses a flexible printed circuit (FPC) equipped with double rows of golden fingers and a mobile terminal. The FPC comprises a body, a first branch arm and a second branch arm. The first branch arm and the second branch arm are both connected with the body. The first branch arm, the second branch arm, and the body are integrally formed. The first branch arm is provided with a first row of golden fingers. The second branch arm is provided with a second row of golden fingers. The first branch arm is overlaid with the second branch arm. The mobile terminal is provided with the FPC. The first branch arm and the second branch arm form the structure of the double rows of golden fingers after being overlaid. The wires of the first row of the golden fingers can be directly laid on the first branch arm and is not required to thread through the second row of the golden fingers. Thus, the distance between the golden fingers of the second row of the golden fingers can be decreased so that the sizes of the second row of the golden fingers can be reduced in the arrangement directions of the second row of the golden fingers. Further, the distance between the wires of the first row of the golden fingers can be decreased so that the first row of the golden fingers can be arranged densely, that the overall area of the golden finger end on the FPC can be decreased, and the miniaturization of a terminal device benefits.
Description
technical field [0001] The invention relates to flexible circuit board technology, in particular to a flexible circuit board with double rows of gold fingers and a mobile terminal. Background technique [0002] Flexible printed circuit (FPC, Flexible Printed Circuit) is a commonly used electrical connection device in various mobile terminals. One end is designed with a gold finger for connecting with the connector. In order to reduce the width of the flexible printed circuit, the gold finger is designed as two The first row of gold fingers closer to the end of the flexible circuit board needs to pass through the gap between the second row of gold fingers. In order to ensure a safe distance, the first row of gold fingers leads to the second row of gold fingers. The distance between the golden fingers is relatively large, thereby increasing the width of the flexible circuit board, which is not conducive to the miniaturization of the device.
