Description
Technical field
The present invention is about a kind of pin wiring structure of card insertion end of flexible printed circuit board, in particular to a kind of pin wiring structure with card insertion end of flexible printed circuit board of layering Wiring structure.
Background technology
The pin wiring structure of the card insertion end of flexible printed circuit board of general market, be mainly with reference to the suggestion size in the connector specifications and make, the live width and the line-spacing of staggered pin (pin) are little, and for after avoiding inserting connector (connector), its inner pin contacts with flexible printed wiring board adjacent leads cabling and causes short circuit, and the dimensional tolerance keyholed back plate of the wrong pin of old friend is also accurate.
Use the more connector of number of pins more and more frequent now, the more size of card insertion end that means of number of pins must become big, external form, total spacing equidimension but need be kept certain precision, after just guaranteeing plug-in card, can the false touch adjacent leads and short circuit, but be subject to flexible printed wiring board supplier's processing procedure ability, if need to keep certain precision, it is produced yield and can reduce, and the beard and hair bag makes for the supplier that high accuracy processing procedure ability is arranged, therefore cause this flexible printed wiring board cost to improve, Jiao Cuo fine rule is easily in use side, because of the external force bending causes away thread breakage in addition.
Please refer to Figure 1A and Figure 1B, it is the pin wiring schematic diagram of known card insertion end of flexible printed circuit board, and wherein Figure 1A is a top view, and Figure 1B is a profile.The card insertion end 1 of known flexible printed wiring board from top to bottom is made up of a protective layer 10, a copper foil layer 11, a substrate 12, a copper foil layer 13, a protective layer 14 and a stiffening plate 15 in regular turn.Copper foil layer 11 is that etched (pin 111 is the odd number pin with the staggered pin 111 and 112 that is formed for being connected with the connector (not shown) usefulness, pin 112 is the even number pin), interconnected in order to reach, it is interconnected with pin 112 that pin 111 has cabling partly 1110; Yet because processing procedure precision and the restricted problem of pin widths, those cablings 1110 rupture because of bending easily or cause short circuit because of the false touch adjacent leads.
See also Fig. 2 A and Fig. 2 B again, those are graphic to be the pin wiring schematic diagram of known card insertion end of flexible printed circuit board, and it shows another known pin wiring structure, and wherein Fig. 2 A is a top view, and Fig. 2 B is a profile.Card insertion end 2 wherein from top to bottom is made up of a protective layer 20, a copper foil layer 21, a substrate 22, a copper foil layer 23, a protective layer 24 and a stiffening plate 25 in regular turn.Wherein Jiao Cuo pin 211 and 212 is to form (pin 211 is the odd number pin, and pin 212 is the even number pin) with plating mode, and is interconnected in order to reach, and it is interconnected with pin 212 that pin 211 has cabling partly 2110; Similarly, because processing procedure precision and the restricted problem of pin widths, the cabling 2110 between adjacent leads ruptures because of bending easily or causes short circuit because of the false touch adjacent leads.
Edge this, the inventor of this case works out a kind of pin wiring structure that utilizes the layering cabling, it can overcome the defective of known techniques.
Summary of the invention
Main purpose of the present invention is to provide a kind of pin wiring structure of card insertion end of flexible printed circuit board, and it is required precision, saving cost when utilizing the layering cabling to reach the reduction manufacturing, with the purpose that prevents to open circuit.
For reaching above-mentioned purpose, the invention provides a kind of pin wiring structure of card insertion end of flexible printed circuit board, comprise the conduction element of a substrate, one first conductive layer, one second conductive layer and plural number; This first conductive layer is located at the one side of this substrate, and be formed with first cabling of plural number, those first cablings electrically connect stretches first pin that is provided with plural number, and this first conductive layer differs from second pin that this first Pin locations is provided with plural number, and this second pin and those first cablings, those first pins are discontiguous off state, this second conductive layer is located at the face in addition of this substrate, and be formed with second cabling of plural number, this second cabling extends to the relative position of this second pin relatively, distinguishes electrical communication in those second pins and this second cabling for those conduction elements.
Further understand and approval for having for structure purpose of the present invention and effect, cooperate diagram to describe in detail now as after.
