Description
[technical field]
The utility model relates to a kind of multisection type slot electric connector, refers in particular to a kind of multisection type slot electric connector that can realize that excellent electrical property connects.
[background technology]
The insulating body of slot electric connector commonly used mostly is one-body molded at present, is installed with the electric connector of a plurality of conducting terminals in the described insulating body.
Described slot electric connector generally uses SMT (Surface Mount Technology surface mounting technology promptly utilizes the professional automatic assembly equipment of a cover surface mount assembly directly to be pasted, is soldered to a kind of electronics tipping technology of circuit board surface) to be weldingly fixed on the circuit board.Yet, this solder technology needs higher temperature than crest scolding tin, at the described slot electric connector of heating to melt scolder wherein and then it to be welded in the process on the described circuit board, buckling deformation will take place because of bearing high temperature in described insulating body, and, because described insulating body is long, make that the two ends of described insulating body are very big to the amplitude away from the direction generation warpage of described circuit board, the described conducting terminal of part that causes being contained in described insulating body two ends can't be kept at grade, cause the described conducting terminal of part to have scolder and sky occurs and weld phenomenon, and then influence the normal electric connection of described slot electric connector and described circuit board.
Multisection type slot electric connector for avoiding buckling deformation to concentrate on the two ends of described slot electric connector, now having developed, wherein, a kind of known multisection type slot electric connector as shown in Figure 1.Described multisection type slot electric connector is arranged on the circuit board (not shown), the one first insulating body a and the one second insulating body b that comprise adjacent and mutual pivot joint, accommodate a plurality of conducting terminal c of being arranged in described first insulating body a and the described second insulating body b (for accompanying drawing clear, Fig. 1 the described conducting terminal c in display part) and be located at two liftout attachment d on described first insulating body a and the described second insulating body b respectively.The described first insulating body a has one first inserting groove a1, and the described second insulating body b has one second inserting groove b1.Under the described slot electric connector situation identical with described multisection type slot electric connector length, the described first insulating body a of described multisection type slot electric connector and the length of the described second insulating body b are shorter, can effectively prevent from very big buckling deformation to take place adopting SMT (surface mounting technology) described multisection type slot electric connector to be welded in the process on the described circuit board (not shown).
Yet, the described first insulating body a and the described second insulating body b of described multisection type slot electric connector generally are articulated, and, be matched in clearance between the two, therefore be very easy to shake after being articulated, thereby cause wherein certain section described insulating body secundly generation lateral bending, making can not be correctly to slotting with the hole on the described circuit board (not shown) with the stitch of the described conducting terminal c of described multisection type slot electric connector, and then the described stitch of bending, perhaps, cause the stitch of described multisection type slot electric connector can't be corresponding one by one with the solder joint on the described circuit board (not shown), influence welding effect, cause described multisection type slot electric connector to realize electrically connecting normally with described circuit board (not shown).
In addition, behind certain section described insulating body generation lateral bending, will cause described first inserting groove a1 and the described second inserting groove b1 can not be positioned at same center line, after described multisection type slot electric connector is soldered to described circuit board (not shown), corresponding electronic cards (not shown) grafting can't be gone into described multisection type slot electric connector, cause to realize the normal electric connection of described electronic cards (not shown) and described circuit board (not shown).
Therefore, be necessary to design a kind of new multisection type slot electric connector, to overcome above-mentioned defective.
[utility model content]
