Abstract
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.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
Embodiments provide a kind of mobile terminal, this mobile terminal can be any terminal equipment, such as: panel computer, mobile phone, electronic reader, remote controller, personal computer (PersonalComputer, PC), notebook computer, mobile unit, Web TV, wearable device etc.This mobile terminal comprises mainboard and electronic component, and electronic component can be camera, button etc.Mobile terminal has flexible PCB, is connected between electronic component with mainboard by flexible PCB.
See Fig. 1-3, be a kind of flexible PCB 100 with double golden finger that preferred embodiment in the present invention provides, comprise main body 3, first support arm 1 and the second support arm 2, first support arm 1 is all connected with main body 3 with the second support arm 2 and three in one is shaping.
As shown in Figure 1, the one end away from main body 3 on the first support arm 1 is provided with first row golden finger 11; One end away from main body 3 on second support arm 2 is provided with second row golden finger 21; Second support arm 2 laminates on the first support arm 1, and first row golden finger 11 is positioned at the side place of second row golden finger 21 away from main body 3, is staggered to make first row golden finger 11 and second row golden finger 21.
The bearing surface of first row golden finger 11 and both second row golden fingers 21 is towards identical, and the bearing surface of first row golden finger 11 is towards the second support arm 2.The surface that on bearing surface and golden finger and connector, metal clips abuts against.First row golden finger 11 and second row golden finger 21 be the side place of the second support arm 2 on flexible PCB 100 all, and second row golden finger 21 can not block first row golden finger 11 formation, and both guarantees all can be electrically connected on connector.
First support arm 1 and the second support arm 2 laminate rear formation two and arrange golden finger structure, the cabling of first row golden finger 11 can directly on the first support arm 1, thus without the need to interting from the second row golden finger 21 on the second support arm 2, the spacing between each golden finger in second row golden finger 21 can be reduced, thus reduce the size on each golden finger arragement direction of second row golden finger 21, simultaneously, spacing between the cabling of first row golden finger 11 can reduce, the size on each golden finger arragement direction of first row golden finger 11 can be reduced, make to arrange between golden finger tightr, reduce golden finger entire area on flexible PCB 100, to reduce the corresponding size of flexible PCB 100, the size of corresponding connector can be reduced simultaneously, be beneficial to the miniaturization of terminal equipment.
As preferably, the first support arm 1 and the second support arm 2 bond together.In specific implementation process, can be undertaken bonding by bonded adhesives or double faced adhesive tape between the first support arm 1 with the second support arm 2, be beneficial to the first support arm 1 and the second support arm 2 to overlap together.
First row golden finger 11 is identical with the golden finger number of both second row golden fingers 21, to make first row golden finger 11 roughly the same with the size of both second row golden fingers 21 in the orientation of golden finger.First support arm 1 can be identical with the width of the second support arm 2, overlaps together to make the first support arm 1 and the alignment of the second support arm 2, to ensure the minimized in size of flexible PCB 100.
Shift to install between first row golden finger 11 and the golden finger both second row golden finger 21, namely the golden finger in first row golden finger 11 can position between two golden fingers of corresponding second row golden finger 21, when being plugged in connector by flexible PCB 100, the metal clips that connect corresponding to second row golden finger 21 can be avoided to touch first row golden finger 11 and produce the faults such as incorrect link.Certainly, in other embodiments, also can arrange for aliging between first row golden finger 11 with second row golden finger 21.
Gap between first row golden finger 11 and second row golden finger 21 is 0.2mm-0.3mm, after guaranteeing to laminate between the first support arm 1 and the second support arm 2, and the safe spacing between first row golden finger 11 and second row golden finger 21.
First support arm 1 is the strip extended in the same direction with both main bodys 3, to make for overall strip between the first support arm 1 and main body 3, to make flexible PCB 100 monnolithic case succinct, is convenient to processing preparation.
Shown in composition graphs 1 to Fig. 3, the second support arm 2 is parallel to the first support arm 1, and its one end is connected to the lateral edges place of main body 3, so that the cabling between main body 3 and the first support arm 1, second support arm 2 is arranged.The first support arm 1 is relative with the second support arm 2 launch time, flexible PCB 100 entirety can be H type, and when the first support arm 1 and the second support arm 2 overlap together, the two is yi word pattern, is straight strip.
When the first support arm 1 is relative with the second support arm 2 launch time, the first support arm 1 and the second support arm 2 interval arrange and are parallel to each other, and clearance D is therebetween 0.8mm-1.2mm.When processing preparation, first flexible PCB 100 is processed to form H type, gap between first support arm 1 and the second support arm 2 is 0.8mm-1.2mm, is beneficial to the processing and fabricating of flexible PCB 100, can conveniently be bent by the first support arm 1 and be laminated on the second support arm 2 simultaneously.As preferably, the gap between the first support arm 1 and the second support arm 2 is 1mm.
First support arm 1 is provided with coverlay 12 on the surface of the second support arm 2, the position hollow out of the corresponding second row golden finger 21 of coverlay 12, to form a groove 10 on the first support arm 1, after first support arm 1 and the second support arm 2 overlap together, the position that second support arm 2 is provided with second row golden finger 21 can be arranged in this groove 10, thus the difference in height reduced between first row golden finger 11 and second row golden finger 21, when groove is darker, first row golden finger 11 can be made concordant with second row golden finger 21.On this basis, the back side that the second support arm 2 can also be provided with second row golden finger 21 place hollows out formation groove, to reduce the thickness of second row golden finger 21 position, is beneficial to make first row golden finger 11 concordant with second row golden finger 21.
Further, between the first support arm 1 and the second support arm 2, reinforcement steel disc can be set, to improve the structural strength of flexible PCB 100, be convenient to strengthen being fixedly connected with of steel disc simultaneously.Strengthening steel disc can extend to outside flexible PCB 100, strengthen steel disc to be connected with other structural members in mobile terminal, can utilize and strengthen the heat radiation that steel disc can be beneficial to flexible PCB 100, avoid the heat of the first support arm 1 and the second support arm 2 to distribute in time and to affect electrical connection properties.
Above execution mode, does not form the restriction to this technical scheme protection range.The amendment done within any spirit at above-mentioned execution mode and principle, equivalently to replace and improvement etc., within the protection range that all should be included in this technical scheme.
