Abstract

The invention discloses a pin wiring structure of a card insertion end of a flexible printed circuit board, which comprises a substrate, a first conductive layer, a second conductive layer and a plurality of conducted elements, wherein the first and second conductive layers are arranged on the two surfaces of the substrate respectively; the first conductive layer is provided with a plurality of first wires; the second conductive layer is provided with a plurality of second wires; the first wires electrically extend a plurality of first pins and are provided with a plurality of second pins in different positions from the first pins; the second wires are correspondingly extended to the corresponding positions of the second pins; and the conducted elements are electrically communicated to thesecond pins and the second wires respectively so that the second pins, the first wires and the first pins are in a non-contacted off state to form the card insertion end of the flexible printed circuit board with two layers of wires.

Description

technical field [0001] The present invention relates to a pin wiring structure of a flexible printed circuit board card-inserting end, in particular to a pin wiring structure of a flexible printed circuit board card-plugging end with a layered wiring structure. Background technique [0002] Generally, the pin routing structure of the flexible printed circuit board on the market is mainly made with reference to the recommended size in the connector specification book. The line width and line spacing of the staggered pins (pins) are small, and to avoid insertion into the connector (connector), its internal pins contact with the adjacent pins of the flexible printed circuit board to cause a short circuit, so the dimensional tolerance control of the staggered pins is also more precise. [0003] Nowadays, connectors with a large number of pins are used more and more frequently. The larger number of pins means that the size of the card insertion side must be larger, but the dimens...
