Description
[technical field]
The utility model relates to a kind of electric connector, particularly relevant for a kind of electric connector with flexible flat cable.
[background technology]
Along with the continuous development of electronics technology, flexible flat cable is used to electronic product more and more continually.Flexible flat cable (Flexible Flat Cable, FFC) be a kind of with PET insulating material and zinc-plated flat copper wire as thin as a wafer, by the new types of data cable that the pressing of high-tech automation equipment production line forms, have softness, arbitrarily bending fold, thin thickness, volume is little, connection is simple, convenient disassembly, easily solve electromagnetic shielding advantages such as (EMI).Can select lead number and spacing arbitrarily, make on line more convenient, significantly reduce the volume of electronic product, reduce production cost, enhance productivity, be suitable between moving-member and the mainboard most, pcb board between the pcb board, make the usefulness of data transmission cable in the miniaturization electrical equipment equipment.But softer because of the flexible flat cable material, in use,, may face the difficulty of accurate location if directly peg graft with flexible flat cable.So; in the industry cycle can design a joint construction usually; the flexible flat cable predetermined fixed can be formed a complete electric connector by this joint construction; and then peg graft with other components and parts, just can avoid only directly pegging graft and the difficult problem in location occurring pegging graft with flexible flat cable.
Please refer to and shown in Figure 1 announce a kind of existing electric coupler component 9 that is disclosed for CN 201029126Y number by Chinese patent, it comprises flexible flat cable 90, be attached at reinforcing chip 91 on the flexible flat cable 90, be assembled in insulating body 92 on the flexible flat cable 90, covered the lid up and down 93,94 of insulating body 92 and be assembled in snap close piece 95 on the insulating body 92.Be provided with the golden finger 96 of an exclusive dew at the leading section of flexible flat cable 90.The front end face of the front end face of golden finger 96, flexible flat cable 90 front end faces, reinforcing chip 91, continuous grafting end face of the common formation of the front end face of lower cover 94.When electric coupler component 9 and butt connector (not shown) when docking, this continuous grafting end face inserts in the slot of butt connector, make the upper surface of golden finger 96 electrically contact, thereby make that carrying out signal between electric coupler component 9 and butt connector transmits with the butt joint terminal of butt connector.
In above-mentioned prior art, in order to ensure carrying out stable signal transmission between electric coupler component 9 and the butt connector, the butt joint terminal of butt connector must closely be resisted against the upper surface of golden finger 96, makes the butt joint terminal can keep the stable electrical effect that contacts with golden finger 96.But this close mating relationship, when making existing electric coupler component 9 in inserting butt connector, the front end face of the front end face of flexible flat cable 90 and golden finger 96 can be subjected to come from the thrust of docking terminal, make the front end face of flexible flat cable 90 be lifted, and cause flexible flat cable 90 to be difficult to insert in the slot of butt connector; Perhaps might make golden finger 96 peel off from the upper surface of flexible flat cable 90, and cause flexible flat cable 90 impaired electric connections even to be failed, particularly under the frequent use or repair of pegging graft of needs, the phenomenon of peeling off that is positioned at the golden finger 96 on the flexible flat cable 90 can be more serious, have a strong impact on normal signal transmission, the flexible flat cable that must more renew.
Except that above-mentioned defective, have in the production and assembly process of electric connector of flexible flat cable at other, because the front end face of flexible flat cable need guide the flexible flat cable group to go in the insulating body, and the front end face of flexible flat cable is easy to take place the upwards phenomenon of warpage in bootup process, and this warping phenomenon be difficult to after assembling is finished with its correction.So this inborn deficiency is easier to cause butt joint to be failed.
Therefore, be necessary existing electric coupler component is improved, destroyed by butt connector with the structure of avoiding electric coupler component.
