[Previous technology] 10 15 Due to the advancement of electronic technology, various electronic products are of various types, such as personal digital assistants (PDA), digital cameras (DC), digital video recorders (Dv), digital video recorders (MP3), etc. Products are not required to be thin, short, and easy to carry. For this reason, most of the devices used to store electronic data in these electronic products use lighter and thinner electronic cards (referred to as memory cards), and electronic cards are mainly It is made of flash memory, but because each major manufacturer competes for development, each has its own unique specifications, so that there are various types of electronic cards on the market, but they can be divided into MS (MemoryStick), SD (SecureDigital ), MMC (Examination Card), SM (SmartMedia) & xD and other electronic cards. 20 Although the five types of electronic cards mentioned above use flat contact contacts to transmit signals, due to the inconsistent specifications, various electronic cards are not only different in size, but also different in the number of contacts and their location. For electronic devices using electronic cards, 'If it is possible to have an electrical connector that can access multiple electronic cards, it will be the best way to improve the applicability of electronic devices. Based on the consideration of the volume of electronic devices', it cannot be targeted at a single type. The electronic cards of specifications have been designed with a slot that meets their specifications. Otherwise, the size of the electrical connection will be too large. Therefore, the best way is | ^, and the eighth slot can be used for different types of electronics. Card insertion is a better design. 4 As shown in Figure 1 ', taking China Patent Bulletin No. 543884 “Four-in-one Memory Card Plug Port” as an example, a design with a single slot that can be used to plug in four different types of electronic cards is revealed. The electrical connector is mainly provided with an upper terminal base 1 and a lower terminal base 2. The upper terminal base 1 is provided with ten lead terminals 12 for conducting an Ms-type electronic card, and the lower terminal base 2 is provided with 22 Branch lead terminals 22 are used to lead SM-type electronic cards, nine lead terminals 24 are used to lead SD and MMC standard electronic cards, and multiple lead terminals 26, 28 are used for protection or switching. In this way, any one of the four types of electronic cards can be connected with the corresponding lead terminals when inserted, so that a single slot can be used for the four types of electronic cards. However, it can be found from the drawings that the main problems in the design of such electrical connectors are obviously the configuration of the lead terminals and the soldering of the lead terminals to the circuit board. Due to the different specifications of the four types of electronic cards, not only the number of lead terminals is large, but also the configuration must match the position of the electronic card after it is inserted. Due to the restrictions on the number of circuit board layers and the width of the electrical connector, all If the lead terminal is arranged on the same side of the electrical connector as the soldering end of the circuit board, as in the design of a general electrical connector, there will be a risk that it will be too dense to be soldered at the same time, and as disclosed in the case, One end of the lead terminal U connected to the circuit board (not shown) extends beyond the rear end face of the lower terminal block 2, and the _ end of the lead terminal 24, 26, 28 connected to the circuit board extends out of the lower terminal block 2. Outside the front end surface, an upper terminal seat 丨 is further divided, so that the lead terminals 12 are individually connected to the circuit board. Although this method solves the problem of the configuration of the lead terminal, it causes the lead terminal and the circuit board to be divided into three blocks during soldering (one block is located at the rear end of the lower terminal block 1221346 5 10 15 2 The lead terminals 22, _ Pingu are plural lead terminals 24, 26, and 28 at the lower end, and Li Yiguangshi moved to meet her on the 1st month, and the other block is located on the upper terminal block. 1 the rear end of the lead-in terminal 12) and the m 7 cumbersome process. At the same time, because the front and rear ends of the lower terminal block 2 have lead terminals 22 26 28, they must be connected to the circuit board ', so the circuit board must cover the last name; 盍 the distance from the front end to the rear end of the lower sub-mount 2 makes the electrical connector underneath Lei Lu Tuo Hong ^, on the contrary, & the overall thickness of the electrical connector and the circuit board after welding is increased, due to thin and short design trends. On the other hand, the lead terminal is exposed at the front end of the electrical connector provided with the insertion port, which also violates the general layout of the wiring as much as possible, so that the terminal is oxidized or the risk of accidental collision damage is increased. The above are just the shortcomings of the design of an electrical connector that uses a single-plug population for multiple electronic card insertions, while other electrical connectors that also use a single-insert port for multiple electronic card insertions may be The configuration of the lead terminals is different, but it still faces the same problems that the soldering ends of the conductive terminals must be distributed and the process of soldering the circuit board is cumbersome.

A plurality of solder joints 53 corresponding to the second tan end 342 of the second conductive terminal 34 (FIG. 5), so that each solder joint η is electrically connected to the electrical connector 6 through a pre-designed circuit. When the connection is known, the solder joint 53 of the circuit board 5 on the lower side and the second conductive element 34 are connected. After the Ertan terminal 342 is aligned and soldered, the second post of the transfer circuit board 33 is filled with a plurality of solders, and the soldering black corresponding to the upper side of the circuit board 5 10 accounts for 53% of the angle, so that The second soldering portion of the transfer circuit board 33 is electrically connected with a soldering point w corresponding to the circuit board $. This design is characterized by that the soldering ends of all conductive terminals can be located on the side of the insulating body 31, without The fork is limited to the number of conductive terminals: Since the circuit board 5 is a double-layer board, and the application of the adapter circuit board 33 makes all The soldering and sentence of the electrical terminal can be extended to be arranged outside the end surface 32 of the insulating body 3, without "there may be too many dense conductive cakes, which may be too dense. In more detail, the first conductive terminals 32 are large in number, so The first soldering end 322 of the first soldering end 322 can be three-dimensionally arranged on the transfer circuit board 33 in a manner of being divided into three rows of relatively different heights (refer to the imaginary lines of I η and E in FIG. 3). 322 can maintain an appropriate distance, and then use the second dense soldering portion 334 on the circuit board 33 designed by the printed circuit board process to transfer to the circuit board 5, so that it can break the past method of directly soldering to the circuit board. Must be limited by a single-layer circuit board, resulting in the disadvantage that the conductive terminals are too dense to be accommodated on one side of the insulating body. In addition, the circuit board 5 uses a double-layer board that can design circuits on both sides, so that the lower side of the circuit board 5 can be used. It is connected to the second soldering end 342 of the second conductive terminal 34, which further increases the number of conductive terminals that the circuit board 5 can connect to. 2. It is easier to solder the alignment ... Because the lower side of the circuit board 5 is directly connected to The second soldering end 342 of the two conductive terminals 34 is connected by surface adhesion, and the upper side of the circuit board 5 is connected to the transition circuit board 33. Therefore, when the welding operation is actually performed, only the soldering on the lower side of the circuit board 5 is required. Point 11 53 is aligned with the second soldering terminal 第 of the first-conducting terminal 34, and each first soldering portion 334 of the switching circuit board 33 has a fixed space X, which is also compatible with the circuit board 5 The corresponding solder joints 53 on the upper side are aligned in the horizontal direction, and even if the solder joints 53 and the second solder joint have a slight gap in the vertical direction, the soldering of the two is not affected, as long as the solder is attached to the solder joints 53 An electrical connection can be formed within a cool angle formed with the second soldering portion 334. On the other hand, as for the soldering of the first soldering end 322 of the first conductive terminal M and the transfer circuit board 33, because a solder hole is used, and because the space available for configuration between each first soldering end 322 is relatively small, 10, so there is no difficulty in the alignment and welding between the two. Third, the overall height of the electronic device using the electrical connector is low: as mentioned above, because all the conductive terminals of the present invention can be neatly arranged on the same side of the insulating body 31, the circuit board connected to the electrical connector 3 5 does not need: the conventional structure must generally cover the entire electrical connector 3 below, so from the perspective of 15 degrees, after reducing the thickness of the circuit board 5 and the electrical connector 3 stacked on each other, the overall height of the electronic device Naturally reduced, more consistent = thin design trends. To sum up, the electrical connector 3 of the present invention for a variety of electronic card insertions. By designing the transfer circuit board 33, the configuration of the conductive terminals is not limited by a single circuit board, and all conductive terminals can be soldered. The ends are arranged on the same side of the insulating body 31, which is beneficial to Tan Jie operation. And a better way is to apply a double-layer circuit board 5 so that one side is directly welded to the second conductive terminal 34 and indirectly connected to the first conductive terminal by using a transfer circuit board, so that the circuit board 5 may not be required. It is known that the structure of electrical connectors is generally 12 1221346. Because of the problem of the dispersed arrangement of conductive terminals, it is necessary to cover the underside of the electrical connector 3, which greatly reduces the use area of the circuit board 5 and achieves the trend of thin and light products. f 隹 The above is only a preferred embodiment of the present invention. Although the foregoing description is based on an example in which the electrical connector is provided in the PCMCU card, it can actually be used on any electronic device or interface card. In this way, the scope of Bei Shi of the present invention is limited, that is, the simple equivalent changes and modifications made by the patent scope of the present invention and the description of the invention θ Neige should still fall within the scope of the patent of the present invention.
