New description: [New technical field] This is a kind of card edge connector, especially about "high-density expansion card edge connector" [Prior Art] See the connection storage The card edge connector of the module card or expansion card is a single-row terminal design. However, with the trend of high integration and miniaturization of electronic products, more and more card edge connectors of double-row terminal design are used. As shown in Fig. 1, a double row card edge connector 8 is disclosed in U.S. Patent No. 5,024,609. The card edge connector 8 includes an insulative housing 8A, a plurality of upper rows of terminals 8 and a plurality of lower discharges 82. The insulative housing (10) has an upper docking space 800 at the upper portion and a lower docking space 801 at the lower portion. Each of the upper rows of terminals 81 has a contact portion 81 (), a soldering portion 812, and a connecting portion 811 connecting the contact portion 81 and the soldering portion 812. Similarly, each of the lower row of terminals 82 also has a contact portion 82, a The soldering portion 822 and a connecting portion 821 connecting the contact portion 820 and the splicing portion 822. The contact portion 81G of the upper row terminal w is housed in the upper docking space, the contact portion 820 of the lower row terminal 82 is received in the lower docking space 8〇1, and the upper row terminal 81 and the lower row terminal 82 are both The two opposing members are separated by an insulating spacer 8〇3 to prevent mutual electrical interference between the two. When a mating sub-board or memory module card (not shown) having a double row of contacts is inserted into the card edge connector 8 , the upper row of contacts thereon can be in contact with the upper row of terminals 81 . In the upper docking space 8 〇〇 contact, the lower row of contacts on the lower row of contacts can be connected to the contact portion 81 of the lower row of terminals 82 in the lower docking space. i 3 M399470 is in contact with the soldering portion 812 and the lower row of terminals of the upper row of terminals 81.

At the same time, the upper row of terminals 8 丨 and lower row of the card edge connector 8 Terminal 82 is mounted on the same side of the PCB board. ' pcB board requires a larger area to provide more A solder pad for soldering the upper row of terminals 8 of the card edge connector 8 to the lower row of terminals 82: the solder portion of the densely distributed upper row of terminals 81 and the soldering portion 822 of the lower row of terminals 82 necessarily make pcB The space between the corresponding pads on the board is narrow, and the corresponding wiring may be quite difficult. Furthermore, since the contact portion 81 of the upper row of terminals 81 of the card edge connector 8 is at a different height from the contact portion 820 of the lower row of terminals On the one hand, the length of the upper terminal 8 ι and the lower row of terminals 82 are different, so that the elastic forces of the upper row and the lower row of terminals 8 1 , 82 are different; resulting in positive contact force on the contacts on the electronic card when contacting the electronic card Differently, the signal transmission is unstable; on the other hand, the card edge connector 8 has a higher height on one side of the PCB.

A plurality of fresh shovel 42 is disposed on the upper surface of the circuit board 4 on the upper surface of the circuit board 4 corresponding to the soldering portion 211 of the first conductive terminal 21, and the lower surface of the circuit board 4 corresponds to the second conductive end + Μ The plurality of materials 42 are provided at the position of the welded portion. Each of the two ends of the _4 设有 is provided with a receiving hole 44 and a fixing hole 45 extending through the upper and lower plates. The receiving hole material is substantially in the rectangular groove 4 . Between the fixing hole 45 and the fixing hole 45, the first sub-connector 2 (see the main body of the main body: 220) and the ejecting port 222 are received therein to connect the piano 2 (4). The fixing hole 45 is substantially circular and has a diameter smaller than the first sub-connection. The card (four) 331 of the fixing member 33 of the first fixing member 23 of the second fixing member 23 has a slightly smaller width on the second electronic card 5 of the second sub-connector 3. Further, the slot 4 is formed by the upper pair " notch 503 or the first convex portion The rib 24 盥 rib rib 32 is also provided at the position of the fixing hole 4 rib 32 32 M399470 concrete combination of Figs. 8, 9, ι〇, 彳 彳 ϋ 11, the first child connector 2 A fixing member 23 is inserted into the two fixing holes 45 of the circuit board 4 and is tightly clamped therein, and the first and second fixing members 33 of the sub-connector 3 protrude from the outside of the card slot 304. Inserting into all the corresponding fixings 45, the cavity is fixed by the interference of the upper holding portion 331 and the fixing hole 45. The mouth, A, and the holding portion 33 1 of the second fixing member 33 protrudes from the fixing hole 45 The sputum of the D is received in the receiving slot 230 of the first fixing member 23. When the ejecting member 22 is in the released state, the electronic card 5 is inserted into the phase from top to bottom. The first insertion slot 2〇4, the slot 4〇, and the first insertion slot 3〇2 are up to the final, spliced position, at which time the first contact pad 500 on the first contact pad is connected to the first sub-connector. The first conductive terminals 21 of 2 are butted, and the second row of contact pads 5〇1盥, the second conductive terminals 31 on the second sub-connector 3 are docked. During the insertion process, the card U is pushed out. The portion 222 thus presses and retracts the ejecting member 22 from its release position to the locked position, at which time the locking portion 223 is rotated such that the C1A is engaged with the locking tab 510 of the locking side 51 of the electronic card 5 to lock it. ^ When the card is retracted, the operation unit 221 is required to press the card ejecting member 22 from the card locking position to the k card position, and the ejecting portion 222 pushes the electronic card 5 out of the card edge connector 1. 'Because the first child violates the girl. „Theft in 4', the second sub-connector 3 has the advantage of installing the connector respectively.==The card edge of the ordinary single-row terminal design and the second conductive terminal 31 can be; The first conductive terminal 21 of the device 1 occupies only the wiring space of the soldering pads on the two boards of the board area 4 of the board. Secondly, the present P has 'and the circuit board has The first conductive terminal 21 and the second conductive member 31 having a relatively large H乍 can be designed in the same structural shape, so that the upper row of contact pads 500 of the electronic card M399470 5 and the lower row of contact pads 501 are identical when docked. The positive contact force ensures stable signal transmission. Furthermore, the card edge connector of the present invention allows the electronic card 5 to partially sink to the circuit board 4 after being inserted, and has a lower height on the circuit board 4. The card edge connector 1 of the present invention is provided with a double-row conductive terminal under the condition of reducing the height, width and length of the insulating body with respect to the card edge connector designed by the existing double-row terminal, and can ensure stable transmission of k number. Compared with the existing single-row terminal card edge connector, the double-row conductive terminals are disposed without high height, width and length to achieve high-density expansion, and the number of conductive terminals is increased to perform high-speed signal transmission of more lines. . The above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. The type of the board, the manner in which the first sub-connector 2 and the second sub-connector 3 are fixed to the circuit board 4, the structure of the conductive terminals, and the like can be selected by those skilled in the art according to actual needs. The technical content and technical features of the present invention have been disclosed as above, but those skilled in the art may still make various substitutions and modifications based on the teachings and disclosures of the present invention without departing from the spirit of the present invention.
