Description
[technical field]
The utility model relates to a kind of board to board connector, refers in particular to a kind of board to board connector that is applied to field of mobile phones.
[background technology]
Existing board to board connector and combination variety thereof are various, along with the development of communications industry, and the especially development of mobile phone and function thereof variation with rapid changepl. never-ending changes and improvements, the connector that is applied to field of mobile phones is also constantly changing to give the demand for development that satisfies mobile phone.For comply with little, thin, light trend of mobile phone development and mobile phone signal the transmission accuracy and stability, the structure of the connector that is mated, the assembling particularly important.Two buttcover plates of existing board to board connector generally connect by buckle, and are perhaps fastening by retaining sheet.The connector that discloses for No. 2404227 as No. the 5876217th, United States Patent (USP) and No. 5836773, Chinese patent.Yet the design of the card holding structure of above-mentioned board to board connector is complicated, use is inconvenient, terminal can not realize that excellent electrical property connects during two buttcover plate butt joints, the stability and the accuracy of signal transmission have been influenced, and, because complex structure, increase the complexity of making, improved manufacturing cost.
[utility model content]
The purpose of this utility model is to provide a kind of accurately board to board connector of butt joint of being convenient to, make two buttcover plates can realize good closed butt joint, and then the terminal that makes board to board connector reaches the excellent electrical property connection, the stability and the accuracy of the transmission of realization signal.
For achieving the above object, the utility model adopts following technical scheme: the utility model board to board connector comprise loam cake, pedestal and be contained in loam cake respectively and pedestal in first, second terminal group.The loam cake two ends are equipped with and are provided with the subordinate location notch between projection, location-plate and projection and location-plate.The pedestal two ends are provided with the holding section that cooperates with projection, accommodate the main locating slot of location-plate and are contained in reference column in the subordinate location notch corresponding to the loam cake two ends.
Compared to prior art, advantage of the present utility model is: described board to board connector loam cake and pedestal two ends correspondence are provided with card holding structure and location structure, by resetting, hold, can make loam cake and pedestal realize closed butt joint, thereby guarantee the good electrically contact of terminal, and then guarantee the stability and the accuracy of signal transmission.And, because the location, card holding structure is one-body molded respectively on loam cake, pedestal, can reduce the complexity of manufacturing, the minimizing manufacturing cost.

[embodiment]
Please refer to Fig. 1 to shown in Figure 6, the utility model board to board connector (not label) comprises loam cake 1, terminal module 2 and pedestal 3.
The loam cake 1 lengthwise body that roughly is square comprises the end (not label) on main part (not label) and main part both sides.Main part comprises upper surface 10, lower surface 14, both ends include the projection 11 that is located at both sides, middle location-plate 12 and be located at projection 11 and location-plate 12 between subordinate location notch 13.Wherein, projection 11 is imperfect hexagon, and location-plate 12 lower ends are one and are inverted terrace with edge shape.
The pedestal 3 lengthwise body that roughly is square comprises the end (not label) on main part (not label) and main part both sides.Pedestal 3 main parts comprise inner surface 30, outer surface 31 and plurality of terminals accepting groove 304, and wherein, the main part both sides are prolonged terminal containing slot 304 and stretched out and be provided with some bayonet sockets 307, and 307 of bayonet sockets are provided with isolation part 306.In addition, pedestal 3 main parts also are provided with and run through inside and outside surperficial 30,31 and some through holes 308 of communicating with terminal containing slot 304.Pedestal 3 both ends include holding section 302, main locating slot 301 and be located at holding section 302 and main locating slot 301 between reference column 300.Holding section 302 projections form draw-in groove 309.
During assembling, at first first, second terminal group is assembled into respectively on loam cake 1 and the pedestal 3, wherein the first terminal 21 is one-body molded with loam cake 1, upper surface 10 levels of first weld part 210 and loam cake 1, and first contact 211 protrudes out the lower surface 14 of loam cake 1.The contact site 222 of second terminal 22 inserts in the terminal containing slot 304 of pedestal 3, dome 220 pushes against with terminal containing slot 304, second weld part 223 be fastened in pedestal 3 bayonet socket 307 and with pedestal 3 outer surfaces 31 levels, the slot 221 on second contact site 222 is positioned at through hole 308 belows of pedestal 3.Then, loam cake 1 and pedestal 3 are assembled into together, wherein, the location-plate 12 at loam cake 1 two ends inserts the main locating slot 301 at pedestal 3 two ends respectively, the subordinate location notch 13 at loam cake 1 two ends closely cooperates with reference column 300 on the pedestal 3, the projection 11 at loam cake 1 two ends respectively with pedestal 3 on holding section 302 link closely.At last, the first terminal 21 protrudes out the slot 221 of first contact site 211 of loam cake 1 lower surface 14 by through hole 308 insertions second terminal 22 of pedestal 3 inner surfaces 30, realizes electrically contacting with second terminal 22.
