[background technology]
Along with, the continuous development of electronic technology, flexible circuit board connector is applied in the electronic installations such as mobile phone, keyboard, hard disk drive, facsimile machine more and more widely.As the formation of promptly having introduced flexible PCB among " History of FFC/FPC " (Connector Specifier, Februray 2001), terminal design and several development trend that is installed in the flexible circuit board electrical connector assembly on the printed circuit board (PCB) of flexible circuit board electrical connector assembly.
At present a kind of electric coupler component 1 ' that generally adopts as shown in Figure 5, it comprises that insulating body 2 ', winding go up rotatable gland 4 ' and be plugged on conducting terminal 3 ' in the insulating body 2 ' at insulating body 2 '.Gland 4 ' two ends are provided with projection 44 ', insulating body 2 ' comprises that lengthwise shape matrix 22 ' reaches by the extended card arm 24 ' in the relative both sides of matrix, two card arms 24 ' are equipped with a semicircle location notch 240 ', location notch 240 ' is formed with a continuing surface 242 ', projection 44 ' is formed with the bearing surface 442 ' that matches with the continuing surface 242 ' of location notch 240 ', gland 4 ' is installed on insulating body 2 ' by projection 44 ' rotation, when gland 4 ' is in the enable possition, flexible PCB can be installed on electric coupler component 1 ' with zero insertion force, when the rotation gland is in the close position it, gland will compress the conducting terminal 3 ' of flexible PCB and electric coupler component 1 ', and its two foundation is electrically connected.But because the continuing surface 242 ' of location notch 240 ' and the bearing surface 442 ' of projection 44 ' are smooth semicircle curved surface, projection shape 44 ' can be more or less freely in location notch 240 ', rotate, this just makes gland 4 ' just rotated by external force and leaves make position and cause gland 4 ' can not reliably compress flexible PCB, thereby influences the stable electric connection between flexible PCB and electric coupler component 1 '.
A kind of electric coupler component of intrinsic necessary design is to overcome above deficiency.
[utility model content]
The purpose of this utility model is to provide a kind of electric coupler component, and this electric coupler component can be fastened in the flexible PCB that is mated in the electric coupler component reliably.
The purpose of this utility model is achieved in that a kind of electric coupler component that is used to connect flexible PCB, and it mainly comprises: lengthwise shape insulating body, be contained in plurality of conductive terminals in the insulating body, the actuator that is connected with group with insulating body and be coated on metal shell on the insulating body.Insulating body comprises that lengthwise shape matrix reaches by the extended card arm in the relative both sides of matrix, the inboard of this card arm is provided with the location notch of the continuing surface of tool broken line profile, the rotation that the bearing surface that the projection of actuator is formed with the tool broken line profile identical with the location notch shape is beneficial to the two cooperates, because the contact-making surface of projection and location notch is the curved surface of tool broken line profile, so must overcome certain blocking force when after projection is in the close position, opening again, thereby make this electric coupler component reliably flexible PCB to be locked in the electric coupler component.
Compared with prior art, the utlity model has following advantage: the set location notch and the projection of projection all have the broken line profile on the card arm of electric coupler component, make to have certain blocking force after the actuator locking, can reliably flexible PCB be locked in the electric coupler component.
