Description
Technical field
The present invention relates to a kind of FPC electric power connector conductive metal terminals of suitable SMT technical field.
Background technology
The function of electric power connector mainly is exactly to lean on conducting terminal that telecommunication is passed to another Circuits System from a Circuits System, so conducting terminal is the function hinge center of electric power connector.After conducting terminal is inserted into the rubber base terminal groove, must guarantees that conducting terminal is firm and good electrically conducting effect is arranged, and must guarantee that the contact positive force of terminal contact is enough big; Be enough to let telecommunication smoothly through contact-making surface, if the contact positive force is not enough, then the microcosmic situation of contact-making surface is to have only trickle some contact; Depend merely on fragmentary minutia contact; Its resistance value possibly arrive several ohms greatly, causes too big potential drop, and the telecommunication receiving terminal can't be handled.Because the connect-disconnect life of general FPC connector fixes on about 30 times; This represents the mutual timing of terminal must be to do flexible distortion could when the EOT of anti-the plug, still possess suitable contact positive force; If the terminal material hardness of selecting for use is low, then be difficult to guarantee the not easy fracture of tiny conducting terminal.In addition, the gold-plated thickness in the contact zone of terminal also must be able to bear tens of times abrasion.
The shape specification of terminal except considering the contact impedance that coating and positive force determined of contact-making surface, must be considered the Conductor Impedance of terminal itself, and this just depends on material, the size of terminal.But the good mechanical properties of brass conductive property only is fit to do general terminal; But the relatively poor elasticity of phosphor-copper conductivity is better, can make flexible terminal; Beryllium copper is with good springiness, the good characteristic of conductivity, but material expensive, obtain the problem that difficulty has environmental protection again.
Another electrical characteristic of terminal is a rated current; This depends on the material and the sectional area of terminal, and the impedance of the bigger then unit length in cross section is littler, and the heat that institute's galvanization is produced is fewer; Then terminal temperature ascensional range is less; Also just can conduct bigger electric current, when terminal transmitted this electric current, the self-temperature ascensional range was no more than 30 ℃.
The leg design of SMT product; A zigzag bending is preferably arranged to avoid excessive thermal stress on the solder joint at horizontal segment; In addition; The angle that really will eat that section terminal tails and the horizontal plane of tin can not be too big, has only end or bending point place eats tin otherwise cause, all can not be through the check of SMT scolding tin.The plating of terminal will note avoiding zinc-plated district directly to link to each other with gold-plated district, in order to avoid the bad situation of tin of overflowing takes place in the SMT processing procedure.
General FPC electric power connector is provided with preceding latch mechanism on the FPC/FFC soft arranging wire inserts mouth, when the FPC/FFC soft arranging wire swings up and down, make by seat easily and unclamp, thereby cause the FPC/FFC soft arranging wire to get loose, and steadiness is not strong.In order to overcome this drawback; A kind of conductive metal terminals with leverage must be set; After the FPC/FFC soft arranging wire gets into the FPC electric power connector, when setting level downwards, the insertion mouth of FPC electric power connector is locked through the leverage of conductive metal terminals by seat; When upwards erectting 90 ° by seat, the leverage through conductive metal terminals is unclamped the insertion mouth of FPC electric power connector, is convenient to the FPC/FFC soft arranging wire and inserts or extract, and therefore in order to overcome the above problems, my department is studied conductive metal terminals.
Summary of the invention
