top limit walls bottom limit walls bottom shoulder walls rear limit walls card accommodating groove 14 with a fifthcard receiving space 145 adapted to receive the XD card (i.e., the fifth electronic card) 7 therein, as shown inFIGS. 11 and 12 . - The conductive terminal means is mounted on the
dielectric connector housing 1, extends into thecard accommodating groove 14, and is adapted to contact electrically the conductive contacts on one of the first to fifthelectronic cards open side 11 of thedielectric connector housing 1. In this embodiment, the conductive terminal means includes a set of firstconductive terminals 31, a set of secondconductive terminals 32, a set of thirdconductive terminals 33, and a set of fourthconductive terminals 34, as shown inFIG. 2 . - The first
conductive terminals 31 are mounted on therear wall 12. Each firstconductive terminal 31 has a firstcoupling end portion 311 extending outwardly of therear wall 12 through a corresponding one of a plurality ofmounting holes 121 in therear wall 12, and a first contactingend portion 312 opposite to the firstcoupling end portion 311, projecting into the firstcard receiving space 141, and adapted to contact electrically a corresponding one of the conductive contacts on theMS card 3 when theMS card 3 is inserted into the firstcard receiving space 141 through the frontopen side 11 of thedielectric connector housing 1. - The second
conductive terminals 32 are mounted on the firstinner mounting surface 1111 of thetop wall 111. Each secondconductive terminal 32 has a secondcoupling end portion 321 extending outwardly of therear wall 12 through a corresponding one of themounting holes 121 in therear wall 12, and a second contactingend portion 322 opposite to the secondcoupling end portion 321, projecting into the secondcard receiving space 142, and adapted to contact electrically a corresponding one of the conductive contacts on theSMC card 4 when theSMC card 4 is inserted into the secondcard receiving space 142 through the frontopen side 11 of thedielectric connector housing 1. - The third
conductive terminals 33 are mounted on the secondouter mounting surface 1122 of thebottom wall 112. Each thirdconductive terminal 33 has a thirdcoupling end portion 331 extending outwardly of therear wall 12, and a third contactingend portion 332 opposite to the thirdcoupling end portion 331, projecting into the third and fourthcard receiving spaces SD cards 5, 6 when said one of the MMC andSD cards 5, 6 is inserted into the corresponding one of the third and fourthcard receiving spaces open side 11 of thedielectric connector housing 1. In this embodiment, thebottom wall 112 of thedielectric connector housing 1 is formed with a throughhole unit 1124 which permits extension of the third contactingend portions 332 of the thirdconductive terminals 33 into the third and fourthcard receiving spaces - The fourth
conductive terminals 34 are mounted on the firstouter mounting surface 1112 of thetop wall 111. Each fourthconductive terminal 34 has a fourthcoupling end portion 341 extending outwardly of therear wall 12, and a fourth contactingend portion 342 opposite to the fourthcoupling end portion 341, projecting into the fifthcard receiving space 145, and adapted to contact electrically a corresponding one of the conductive contacts on theXD card 7 when theXD 7 card is inserted into the fifthcard receiving space 145 through the frontopen side 11 of thedielectric connector housing 1. In this embodiment, thetop wall 111 of thedielectric connector housing 1 has a front end portion 1113 formed with a throughhole unit 1114 which permits extension of the fourth contactingend portions 342 of the fourthconductive terminals 34 into the fifthcard receiving space 145 therethrough. - While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
