Description of the Invention: [Technical Field] The present invention relates to an integrated circuit card, and more particularly to a front 5 10 of a thin integrated circuit card with a rear contact and a reverse plug protection. [Prior Art] According to the advancement of electronic technology, various types of electronic devices have become smaller and smaller:: notebook computers, handheld computers (Paim) computers, or personal digital assistants (PDAs), etc. It can be carried around and provide the ability to process data. Therefore, it can provide 'user's great convenience. However, due to its small size, such small electronic devices are only equipped with basic processing circuits, for other extras. The circuit module, for example, the additional memory, is connected to the corresponding integrated circuit card to implement the related functions. The integrated circuit card of the 15 M is reduced in size due to the volume of the integrated circuit, so the volume can be made very small. However, it can be used to set and correspond to the positive integrated circuit card. The number of electronic contacts in the slot contact is extremely limited, and in order to enable the contacts of the integrated circuit card to be reliably and arbitrarily contacted with the terminals of the corresponding slots, the contacts 20 of the general integrated circuit card are disposed at The front edge of the lower surface of the card, as shown in Figure mm, is a mmc (MuhiMediaCard) card with a size of 24x32xl4mm3. On the front edge of the lower surface, only seven contacts u are provided. The MMC card described above is to set a row of contacts on the front edge of the lower surface of the card to serve as the power source, data, address, and control connection for the host terminal 1504888. However, the number of contacts is very small. To provide the aforementioned power, data, address, and control functions, the performance of the card will be greatly limited. For example, the number of shell lines is insufficient to make the data transmission rate too low, or the number of address lines is insufficient. Make the addressable memory space too small. 5 A straightforward solution is to set up another row on the card. Figure 2 shows that there are front and rear row contacts on the integrated circuit card, where the month U is not the contact 21, the standard contact, and the rear row The contact 22 can additionally increase the data transmission rate and the addressable space of the electronic card for additional data addresses and lines. 10 The surface of the general contact is made rectangular, and if the contact is made in the printed circuit, the contact will be higher than the circuit board, so when the contact is made in two rows, between the two contacts Then, a groove is formed. Therefore, as shown in FIG. 3A, when the integrated circuit card having the front and rear row contacts is inserted into the slot 391 of a card reading device 391, the card reading device 39 is as shown in FIG. 3B. The internal schematic diagram, the corresponding contact terminal 311 of the card reader 15 will be in sliding contact with the front and rear contact points, and the terminal 311 will jump in the groove 32. Referring to the side view of FIG. 4, FIG. 4A shows the terminal 311. In the state of contacting the front row of contacts 21, the figure shows that the terminal 311 slides to the groove 32 between the front and rear row contacts 21 and 22, since the contacts 21 and 22 have a considerable height, as shown in FIG. The terminal 3 ιι 20 will fall from the front row of contacts 21 into the recess 32, after which, as shown in the figure, the terminal 311 slides to the rear row of contacts 22 and is lifted. As shown in Figs. 4A to 4c, the terminal 311 is continuously dropped/lifted during the process of inserting and removing the integrated circuit card, which not only easily damages the terminal 3, but also makes the touch feeling poor. 1254888 The appearance of the electronic card of the foregoing Figures 1 and 2 shows that a corner 11 of the outer casing defines a truncated angle 12 to prevent the card from being inserted back into the slot of the host. As shown in FIG. 3, the slot 31 has an internal portion. A complementary to the truncated angle to block the portion 33' when the card is correctly inserted into the slot 31, the truncated angle (2) is matched with the blocking portion 5 33 to correctly position the card, and vice versa, when the card is inserted into the slot, The other corner will interfere with the blocking portion 33 so that the card cannot be inserted into the slot." Due to the rapid advancement of electronic card technology, various types of electronic cards are constantly being introduced, "some of which are designed to be specific." The host side, but at the same time must be compatible with the standard electronic card, therefore, if the standard electronic 10 card is inserted into a specific host end, the host side will be malfunctioned, or the host side circuit must be able to recognize the type of the electronic card. However, it will lead to an increase in cost, which is also inconsistent with the actual demand. In addition, although the volume of the integrated circuit card can be made very small, it is still an important issue to pursue the miniaturization of electronic devices.

Therefore, when the electronic card is inserted into a host slot, as shown in FIG. 12A, even if the terminal of the host slot is moved to the gap between the contacts 7 0 3 and 711, due to the contact 7 斜 3 and 711 beveled edges 8 01 and 8 0 2 are diagonally disposed (relative to printed circuit board $ 2 front end 20 72), therefore, terminal 809 will remain in contact with at least one of contacts 703 and 711, It will not fall/lift, as shown in Figure 12C. Referring to FIG. 12A, the contact 703 further has a bevel 803, and the contact 712 has a beveled edge 8〇4 which is equidistant from the bevel 803. Similarly, the bevels 803 and 804 are similar. The angle of the front end 72 of the printed circuit board 52 is 11 I2s4888, for example, an angle of 30 to 60 degrees, preferably 45 degrees. Therefore, the contacts 703 and 712 also do not cause the terminal 809 to be inserted or removed during the electronic card insertion and removal process. Falling / Lifting 'The other joints in this application have the same beveled design, no longer repeat one by one. 5 is a view showing another example of a plurality of contacts provided on the printed circuit board 52 of the integrated circuit card of the present invention, which is similar to the previous example but has two single-arranged contacts 90^903, and There is a large gap between the power contacts 904 906 and 906 arranged one behind the other to avoid short circuit when the electronic card is inserted and removed. FIG. 14 shows still another example of a plurality of contacts provided on the printed circuit board 52 of the integrated circuit card of the present invention, which is similar to the previous example, but the rear contact 100 has two oblique sides 101. And 1〇2, which are opposite to the oblique sides (1) and 121 of the joints (10) and (4) arranged in the front, respectively. Similarly, the oblique sides 101, 102, m and 121 are formed with the front end 72 of the printed circuit board 52. For example, the angle of 15 30 to 60 degrees, preferably the angle of 45 degrees, therefore, the contact i (10) and the contacts 100 and 120 will not cause the terminal to fall/lift during the insertion and removal of the electronic card.
