Embodiment
Refer to the of the present utility model a kind of electric connector 100 shown in Fig. 1 to Fig. 2, it is upper and in order to grafting electronic cards 200 that this electric connector 100 can be soldered to circuit board (not shown).In the present embodiment, this electric connector 100 comprises insulating body 1, is fixed on the metal shell 3 of conducting terminal 2 on insulating body 1 and coated insulation body 1.
Described insulating body 1 comprises base portion 10, the pair of sidewalls 11 upwards protruded out from the both sides of base portion 10 and the host cavity 12 between described base portion 10 and two side 11.Described host cavity 12 from the rear end face of described insulating body 1 forward recessed formation to accommodate described electronic cards 200.Described base portion 10 is provided with and runs through described base portion 10 along the vertical direction and the terminal groove 101 being arranged into two rows along the longitudinal direction, and described terminal groove 101 is upwards connected with described host cavity 12.Described two side 11 extends to form all along the longitudinal direction, and the outside of each sidewall 11 is provided with some projections 111, and the both sides of described base portion 10 are also provided with the fluting 102 outwards running through described two side 11 in the horizontal direction.
Refer to shown in Fig. 3 to Fig. 4, described conducting terminal 2 is arranged into two rows along the longitudinal direction and is fixed on described insulating body 1, in the present embodiment, described conducting terminal 2 inlays to bury shaping mode and be fixed on described insulating body 1, certainly in other embodiments, the mode that described conducting terminal 2 also can be assembled is fixed on insulating body 1.Described conducting terminal 2 comprise be fixed on described base portion 10 and the frame 21 extended along front and back longitudinally, the afterbody 23 extended forward from the front end of described frame 21 and elastic arm 22.The afterbody 23 of described two row's conducting terminals 2 extends all forward insulating body 1 and arranges in a row in left-right direction.Described terminal groove 101 correspondence is arranged on below described elastic arm 22, namely can be housed in described terminal groove 101 during elastic arm 22 distortion downwards.In the present embodiment, described elastic arm 22 be on described frame 21 punching press or tear shaping rear further upwards bending formed, and then form and the opening 211 that along the longitudinal direction extend corresponding with described elastic arm 22 on described frame 21.Described frame 21 is provided with the first transverse part 212 being positioned at described opening 211 rear, the second transverse part 213 being positioned at described opening 211 front and is positioned at described opening 211 left and right sides and a pair longitudinal part 215 of connection first, second transverse part 212,213 described.Each longitudinal part 215 described is provided with the ear 214 protruded in described opening 211, and extend in described opening 211 more in opposite directions after the self-corresponding longitudinal part of described ear 214 215 bending downwards, described ear 214 is positioned at described terminal groove 101 simultaneously.
Described afterbody 23 extends to form forward from the front end of described second transverse part 213.Described elastic arm 22 is provided with at rear and is integrally connected to the first end 221 of described first transverse part 212, the second end 222 in front and the contact site 223 between first end 221 and the second end 222.The first end 221 of described elastic arm 22 is integrally connected to opening 211 rear end of described frame 21, and the second end 222 of described elastic arm 22 is provided with the clinch 224 being overlapped on corresponding ear 214 upper surface for a pair downwards.Acute angle is formed and V-shaped setting between described two clinchs 224, simultaneously described two clinchs 224 to extend down in described opening 211 thus can reduce the whole height of conducting terminal 2, and described contact site 223 is convex stretches out described frame 21 and bending extends in described host cavity 12 to connect with described electronic cards 200.In other embodiments, described two clinchs 224 also can stride across forward described opening 211 and be overlapped on described second transverse part 213.
The coated described insulating body 1 of described metal shell 3, the both sides of metal shell 3 are provided with some hole clippings 31, and the projection 111 on described insulating body 1 to be held in described hole clipping 31 thus described insulating body 1 is fixed together better with metal shell 3.Described metal shell 3 is also provided with the installation foot 32 extended in fluting 102, described installation foot 32 can be mounted on circuit board thus make metal shell 3 better fixing on circuit boards.
The elastic arm 22 of the utility model electric connector 100 is direct punching presses or tear formation from frame 21, thus is conducive to the height reducing conducting terminal 2, meets the development trend of miniaturization of electronic products.When electronic cards 200 is inserted in the utility model electric connector 100, first end 221 due to described elastic arm 22 is integrally connected to opening 211 place of described frame 21, and the second end 222 is provided with a pair clinch 224 to be overlapped on described frame 21 thus can to prevent contact 223 from excessive deformation occurring downwards, enhance the stress intensity of contact site 223, ensure that contact site 223 docks with the reliable of electronic cards 200, overlapped with two ear 214 phases of frame 21 by two clinchs 224 simultaneously simultaneously, further increase the reliability of overlap joint; Simultaneously because two clinchs 224 of described second end 222 can not enter below described opening 211, and then avoid the surface of two clinch 224 scratch circuit boards.And when electronic cards 200 exits in the utility model electric connector 100, extend in described host cavity 12 because contact site 223 protrudes out described frame 21 and bends, and two clinchs 224 of the second end 222 of elastic arm 22 extend down in opening 211 and be overlapped in the ear 214 of described frame 21, thus can prevent electronic cards 200 from touching the clinch 224 of the second end 222 and then the phenomenon of warpage occurs, produce the phenomenon of the Pin that bursts when namely preventing electronic cards 200 to exit.
Referring again to shown in Fig. 3 to Fig. 7, when blanking punched, described elastic arm 22 is positioned at same flat board with frame 21, the clinch 224 of elastic arm 22 second end does not contact with ear 214, then by elastic arm 22 roughly centre position punching press outwardly, be formed with the contact site 223 protruded out, finally moved towards both sides by a pair clinch 224, this clinch 224 is overlapped in ear 214 respectively.
Electric connector 100 most preferred embodiment of the present utility model is sim card connector, certainly in other embodiments, described electric connector 100 also can be the various card connector of SD card connector or Micro SD card connector or other types or various card unit connector.
Finally it should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted; although be described in detail the utility model with reference to preferred embodiment; have in any art and usually know the knowledgeable; not departing from spirit and scope of the present utility model; when doing a little change and retouching, therefore protection range of the present utility model is when being as the criterion depending on the right person of defining.
