Before the present invention is described in greater detail, it should be noted that like elements are denoted by the same reference numerals throughout the disclosure.
Referring to FIG. 1, the first preferred embodiment of an electrical connector 1 according to the present invention is shown to be adapted for use with a first electronic card 91, such as an SD card, and a second electronic card 92, such as a mini-SD card. Referring to FIGS. 2 to 5, the first preferred embodiment of the electronic connector 1 is shown to include a dielectric housing 2, a cover plate 3, a set of first conductive terminals 5, and a set of second conductive terminals 6.
As shown in FIGS. 2, 4 and 5, the dielectric housing 2 has a bottom wall 21 that has opposite lateral sides 212, opposite lateral walls 22, each of which extends uprightly from a respective one of the lateral sides 212 of the bottom wall 21 and has an upper wall portion 222 and a lower wall portion 221, and a partition wall 24 parallel to and disposed above the bottom wall 21. The partition wall 24 extends between the lateral walls 22, and has opposite ends 241, each of which is connected to a junction of the upper and lower wall portions 222, 221 of a respective one of the lateral walls 22. The partition wall 24 cooperates with the lower wall portions 221 of the lateral walls 22 and the bottom wall 21 so as to confine a first card receiving space 910 (see FIG. 2). The dielectric housing 2 further has a rear side 26, and a front open side 25 for access into the first card receiving space 910. In this embodiment, the bottom wall 21 is formed with a plurality of terminal mounting grooves 211, and has a front end formed with a notch 210 (see FIG. 5). The partition wall 24 is formed with a plurality of terminal mounting grooves 241, and has a front end formed with a notch 240 (see FIG. 4). The dielectric housing 2 further has a rear wall 23 disposed at the rear side 26 and formed with a plurality of mounting holes 231.
As shown in FIGS. 2 and 8, the cover plate 3, which is made of metal, is mounted on the lateral walls 22, and is disposed above the partition wall 24 of the dielectric housing 2 such that the cover plate 3 cooperates with the upper wall portions 222 of the lateral walls 22 and the partition wall 24 so as to confine a second card receiving space 920 (see FIG. 2). The first and second card receiving spaces 910, 920 have different widths. More specifically, the width of the first card receiving space 910 is larger than that of the second card receiving space 920 such that the first card receiving space 910 is adapted to accommodate the wider first electronic card 91 therein and that the second card receiving space 920 is adapted to accommodate the narrower second electronic card 92 therein. In this embodiment, the cover pate 3 has a front end formed with a notch 30. The cover plate 3 is formed with a pair of downwardly extending lateral flanges 4 that flank the lateral walls 22 of the dielectric housing 2, and a plurality of resilient clamping pieces 31 that project into the second card receiving space 920 (see FIG. 2). Each of the lateral flanges 4 is formed with a set of first engaging members 70 in the form of holes. Each of the lateral walls 22 of the dielectric housing 2 is formed with a set of second engaging members 7 in the form of projections corresponding to the first engaging members 70 on the lateral flanges 4. The second engaging members 7 on the lateral walls 22 of the dielectric housing 2 engage respectively and releasably the first engaging members 70 on the lateral flanges 4, as shown in FIG. 2. Each of the lateral flanges 4 is formed with a grounding contact portion 41.
As shown in FIG. 5, the first conductive terminals 5 are disposed on the bottom wall 21 of the dielectric housing 2. Each of the first conductive terminals 5 is mounted in a corresponding one of the terminal mounting grooves 211 in the bottom wall 21, and has a first coupling end portion 52 extending outwardly of the rear side 26 of the dielectric housing 2 and through a corresponding one of the mounting holes 231 in the rear wall 23, and a first contacting end portion 51 opposite to the first coupling end portion 52 and projecting into the first card receiving space 910. In this embodiment, the first contacting end portions 51 of the first conductive terminals 5 are adapted to contact electrically and respectively a set of conductive contacts (not shown) on the first electronic card 91 when the first dielectric card 91 is inserted into the first card receiving space 910 through the front open side 25 of the dielectric housing 2, as shown in FIG. 6.
As shown in FIG. 4, the second conductive terminals 6 are disposed on the partition wall 24 of the dielectric housing 2. Each of the second conductive terminals 6 is mounted in a corresponding one of the terminal mounting grooves 241 in the partition wall 24, and has a second coupling end portion 62 extending outwardly of the rear side 26 of the dielectric housing 2 and through a corresponding one of the mounting holes 231 in the rear wall 23, and a second contacting end portion 61 opposite to the second coupling end portion 62 and projecting into the second card receiving space 920. In this embodiment, the second contacting end portions 61 of the second conductive terminals 6 are adapted to contact electrically and respectively a set of conductive contacts (not shown) on the second electronic card 92 when the second electric card 92 is inserted into the second card receiving space 920 through the front open side 25 of the dielectric housing 2, as shown in FIG. 7.
FIGS. 9 and 10 illustrate the second preferred embodiment of an electrical connector 1′ according to this invention, which is a modification of the first preferred embodiment. In this embodiment, the width of the first card receiving space 910′ is smaller than that of the second card receiving space 920′. The notches 30′, 240′, 210′ of the cover plate 3′, the partition wall 24′ and the bottom wall 21′ are smaller as compared to those of the cover plate 3, the partition wall 24 and the bottom wall 21 in the first preferred embodiment. Furthermore, the first coupling end portions 52′ of the first conductive terminals 5′ extend outwardly of the front open side 25 of the dielectric housing 2′ and through the notch 210′ in the bottom wall 21′. The mounting holes 231′ in the rear wall 23′ respectively permit extension of the second coupling end portions 62 of the second conductive terminals 6 outwardly of the rear side 26 of the dielectric housing 2′.
While the present invention has been described in connection with what is considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments 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.
