Fig. 2 is the sectional perspective view of existing electric connector, to show the winding relation of bonding pad and insulating body.
Fig. 3 is a three-dimensional exploded view of the present utility model.
Fig. 4 is the stereogram that the utility model engages with flexible printed circuit board.
Fig. 5 is the cutaway view of Fig. 4 along A-A.
As shown in Figure 3, the utility model mainly includes members such as insulating body 1, conducting terminal 2 and fixture 3, and wherein insulating body 1 is the extension of lengthwise shape, and its front end surface is concaved with socket 10, is used for going into for butt joint electronic component (not shown) group.Be provided with several in the socket 10 and connect the through hole (not shown) of insulating bodies 1 to surface, its rear end, be used for accommodating and fixing conducting terminal 2 in wherein.Conducting terminal 2 one ends extend in the socket 10 to form and to dock the inserted terminal 21 that electronic component electrically conducts, the relative other end then oppositely extends and protrudes from outside the insulating body 1, and through suitably forming the welding ends 22 that is resisted against on flexible printed circuit board 4 printed circuits 41 (consulting shown in Figure 4) after the bending, described welding ends 22 is positioned at same plane.In addition, insulating body 1 respectively is provided with along the electric connector guide hole 11 (consult shown in Figure 5) suitably recessed with the butt joint direction of the electronic component that docks to relative appropriate position, two ends along lengthwise, reaches the front end of insulating body 1 and respectively be provided with combination slot 12 in abutting connection with guide hole 11 places to accommodate fixture 3 to cooperate guide hole 11.
Fixture 3 comprises lead segment 30 and canned paragraph 31, this canned paragraph 31 L-shaped and its be provided with weld part 310 and main part 311, wherein weld part 310 is en plaque and its and slightly is parallel to the surface of flexible printed circuit board 4 and is welded on the printed circuit 41 of flexible printed circuit board 4 (as shown in Figure 4) with the welding ends 22 of conducting terminal 2, and main part 311 is connected in a lateral margin and the vertical bending of weld part 310 and extends, this main part 311 be en plaque and its highly approximate the insulating body correspondence combination slot 12 height is set.And a lateral margin appropriate position of lead segment 30 autonomous body 311 adjacent weld parts 310 forms to extending away from direction, and be positioned at same plane with main part 311, reach these lead segment 30 relative both side edges and be provided with interference part 301, described interference part 301 is that symmetrically arranged barb-like projection is used for fixing fixture 3 on insulating body 1.In addition, lead segment can also be provided with parallel two extensions, or is provided with to be vertical extension mutually.
See also shown in Figure 4ly, the utility model electric connector is in when assembling, and fixture 3 is assembled on the insulating body 1 with the grafting direction of the electronic component that docks along electric connector, and be symmetricly set in insulating body 1 along lengthwise to relative two ends.Wherein the lead segment 30 of fixture 3 is inserted in the guide hole 11, is fastened in guide hole 11 inwalls by its interference part 301.In addition, after 3 groups of fixtures were gone into suitable length, its main part 311 formed plane abutment were on the surface of carefully closing groove 12, and weld part 310 also relatively is posted by contiguous combination slot 12 places of insulating body 1 near flexible printed circuit board 4 one side end faces.Thereby fixture 3 is gone into along grafting direction liptinite, and stably be retained on the insulating body 1 and can not rock.
In insulating body 1 rear end and the appropriate position that relies on flexible printed circuit board 4 one side end faces extend towards this circuit board 4 and be provided with a reference column 13, this reference column 13 be arranged at insulating body 1 lengthwise to two ends and the fixture 3 that is provided with front end corresponding, when electric connector also is not welded on the flexible printed circuit board 4, this reference column 13 can be inserted in the location hole 42 that cooperates with it on the circuit board 4, be positioned on this circuit board 4 and can be about to electric connector earlier, and provide conducting terminal 2 welding required prestressing force.The weld part 310 of assembling posterior fixation devices 3 is in the same plane substantially with the welding ends 22 of conducting terminal 2, be welded in relative printed circuit 41 places of flexible printed circuit board 4 by surface adhering mode (SMT), its winding is firm and can make electric connector and 4 of circuit boards have stable telecommunication to transmit.
See also shown in Figure 5ly again, fixture 3 main parts 311 are provided with semicircle shape breach 312 in abutting connection with the lateral margin of lead segment 30, cooperate the back to interfere the stress at position to be concentrated with insulating body 1 to prevent fixture 3.Because the cooperation of the lead segment 30 of fixture 3 and the guide hole 11 of insulating body 1 is parallel to the grafting direction, and fixture 3 is fixed on the insulating body 1, and makes it have good assembling stability.The weld part 310 of this fixture 3 and the welding ends 22 of conducting terminal 2 can all be fixed on the rear and front end of electric connector on the flexible printed circuit board 4, and fixture 3 can not separated with insulating body 1 because of the contact engaging and separating force in the external world and had higher winding stability.
