The utility model content

The utility model purpose is to provide a kind of X, Y direction that connects the contact pins in the portable mobile communication terminal that a not board to board connector combination of two parallel printed circuit board (PCB)s in same reference axis is arranged.

The utility model purpose is to provide a kind of board to board connector easy for installation and with low cost combination.

The utility model purpose is achieved through the following technical solutions: the utility model board to board connector group comprises that first connector and second connects, described first, second connector comprises first, second body, one-body molded first, second intrinsic first, second conducting terminal that is arranged on respectively respectively, wherein, first, second conducting terminal electrically contacts with first, second circuit board respectively, and the X of the contact pins of first, second circuit board, Y direction have one not in same reference axis.

The way of contact of the utility model board to board connector combination can also be adopted and compress the way of contact, thereby can improve design flexibility and conserve space.Simultaneously, chamfered has all been made in the installation position of board to board connector combination, and is therefore easy for installation, improves installation accuracy and conserve space.In addition, leave the reinforcement design of opening on first connector as counterpart, thus intensity, resistance performance and the useful life of improving product.

With respect to background technology, advantage of the present utility model is: the utility model board to board connector adopts simple structure to realize contact pins not in same reference axis and the connection between two printed circuit board that are parallel to each other, thereby reduces cost, simplifies flow process.

Embodiment

Please refer to Fig. 1 to shown in Figure 3, the utility model first embodiment board to board connector combination 100 comprises first connector 3 and second connector 5, wherein, first connector 1 comprises first body 32 of longitudinal, is arranged at some first conducting terminals 34 and first power supply terminal 36 in first body 32 in one-body molded mode respectively.First body, 32 longitudinally two side ends are provided with groove 322, and it is provided with two sections breach 321 in the longitudinal direction simultaneously.Please be simultaneously with reference to shown in Figure 4, first conducting terminal 34 comprise first abutting part 341 that protrudes out first body, 32 upper surfaces, from the bending of first abutting part, 341 1 ends extend and be contained in first body 32 in first connecting portion 342 and from first connecting portion 342, first contact site 343 of bending extension upwards.

Second connector 5 comprises second body 52 of longitudinal, is arranged at some second conducting terminals 54 and second source terminal 56 in second body 52 in one-body molded mode respectively.Please be simultaneously with reference to shown in Figure 5, second conducting terminal 54 comprise the weld part 541 that is welded on the second circuit board 8, from weld part 541 upwards second connecting portion 542 that extends of bending, in order to first contact site 343 of first connector 3 electrically second contact sites 543 of contact and the elastic portion 544 that is connected second connecting portion 542 and second contact site 543.Second surface 523 and longitudinally two side ends that second body 522 comprises first surface 522, be oppositely arranged with first surface 522 are respectively arranged with projection 521, second contact site 543 stretches out first surface 522 and is provided with, and second surface is provided with the cascaded surface that longitudinally extends.

Please be simultaneously with reference to Fig. 3 to Fig. 5 and shown in Figure 7, when assembling is used, first connector 3 is installed on the pedestal 6 of external equipment (not shown), boss 61 on the pedestal 6 stretches in the breach 321 on first body 32, tongue 322 on first body 32 is positioned in the corresponding location structure of external equipment, and first contact pins (not label) that is arranged on the first circuit board 7 in the external equipment compresses first abutting part 341 electrically to contact with first conducting terminal 34.Second connector 5 is welded on the second circuit board 8, the projection of second body 54 is contained in external equipment (not shown) and goes up in the corresponding location structure, weld part 541 electrically contacts with second contact pins (not label) on the second circuit board 8, can not increase thereby the bonnet of external equipment 91 is erected on the height that makes on the cascaded surface 524 of second body 52 after 5 assemblings of second connector.When first,
