In order to achieve this and other objects of the present invention, the dual-use memory card connector is suspended in a front extended receiving opening chamber, an upper opening, and two opposite sides, suitable for an MS (Memory Stick) memory card, Two, each having a fastening front tip protruding into the receiving opening chamber, which may be moved between a first position holding the MS Duo memory card in the receiving opening chamber and a second position holding the MS Duo memory card in the receiving opening chamber. An insulated housing having a spring arm and two retaining blocks disposed at two opposing sides in front of the spring arm; A plurality of terminals each mounted on the insulating housing and extending toward the rear side of the insulating housing; A metal upper cover covering the insulating housing, comprising: two holding holes disposed on two opposite sides and respectively coupled to a holding block of the insulating housing; a lateral extended upper suspension spring plate; and a front of the upper suspension spring plate. And a curved retaining portion which protrudes through the upper opening into the front accommodating opening chamber to hold the memory card in the front accommodating opening chamber, and is formed integrally with the two distal portions of the upper suspension spring plate, respectively. A top cover is provided having two limiters for holding the arm in the first position. When an MS Duo memory card is inserted into the receiving opening chamber, the limiter holds the spring arm in the first position, and the curved retaining portion of the spring arm and the spring plate of the top cover connects the inserted MS Duo memory card with the terminal. Keep in contact. When an MS memory card is inserted into the receiving opening chamber, the limiter is pressed by an inserted MS memory card to separate the spring arm from the first position, so that the spring arm is moved to the second position by the spring force. And the MS memory card inserted with the curved retaining portion of the spring plate of the upper cover is in contact with the terminal.

1 to 4, there is shown a dual purpose memory card connector according to the present invention, which is comprised of an insulating housing 10, an upper cover 20, and a plurality of terminals 14. .

The insulating housing 10 includes a front extended receiving opening chamber 11 suitable for an MS memory card, two spring arms 13 suspended on opposite sides thereof, and two opposite sides in front of the spring arms 13. Two retaining blocks 15 are arranged on the side, each spring arm 13 having a fastening front tip 131 projecting into the receiving opening chamber 11 and the fastening front tip 131. There is a ridge 132 projecting from the upper side of the.

The terminals 141 are respectively mounted to the insulating housing 10 and extend to the rear side of the insulating housing 10.

The upper cover 20 is a metal shell, two retaining holes 21 disposed on two opposite sides and respectively coupled to the retaining blocks 15 of the insulating housing 10, and a side extended upper suspension spring. The plate 22 and the front suspension spring plate 22 extending forward and protruding through the upper opening 12 to the inside of the front accommodating opening chamber 11 to form an MS or MS duo memory card. 11 and two limiters 23 integrally formed with two distal portions of the upper and lower suspension spring plates 22 corresponding to the spring arms 13 of the insulating housing 10, respectively. ). The limiter 23 each includes a positioning hole 231 corresponding to the ridge of each of the two spring arms 13 of the insulating housing 10.

5 and 6, usually, the positioning holes 231 of each limiter 23 are respectively coupled to the ridges 132 of each spring arm 13 to move the spring arms 13 to the first position. In this first position, the fastening front tip 131 of each spring arm 13 protrudes into the receiving opening chamber 11 to hold the MS Duo memory card 2.

7 to 12, when inserting the MS memory card 3 into the receiving opening chamber 11, the MS memory card 33 firstly has the curved retaining portion 221 of the upper suspension spring plate 22. The upper suspension spring plate 22 is then pushed upward from the above-described first position to the second position after contact with the front side of the upper side, and the positioning hole 231 of the limiter 23 at the second position. ) Is separated from the ridge 132 of the spring arm 13, so that the MS memory card 3 is inserted in place and kept in reliable contact with the terminal 14.

As described above, due to the structure of the spring arm 13 of the insulating housing 10 that coincides with the positioning hole 231 of the top cover 20, the dual-use memory card connector is connected to the MS Duo memory card 2. In addition, it is suitable for use with the MS memory card 3.

Figure 13 shows a variant of the dual-use memory card connector according to the present invention. According to this variant, each limiter 23 consists of hooks 232 each hooked on the spring arms 13 to hold the spring arms 13 in a first position, each in the first position. The fastening front tip 131 of the spring arm 13 is retained protruding into the receiving open chamber 11 to hold the MS Duo memory card 2. When the MS memory card 3 is inserted into the receiving opening chamber 11, the upper suspension spring plate 22 is urged upwards from the aforementioned first position to the second position, in which the limiter 23 is pressed. The hook 232 of the is detached from the spring arm 13, so that the MS memory card 3 is inserted in place to remain in secure contact with the terminal 14.

The basic type of dual purpose memory card connector is configured to have the features of FIGS. The dual purpose memory card connector works smoothly to provide all of the above features.

While particular embodiments of the present invention have been shown and described, it should be understood that various modifications and changes may be made without departing from the spirit and scope of the disclosed invention.

According to the present invention, it is possible to provide a dual-use memory card connector suitable for use with not only Sony MS memory cards but also MS Duo memory cards.
