Description

  The present invention relates to a socket connector, and more particularly to a socket connector for connecting to a circuit board.

  Along with the enhancement of the functions of the main unit with a built-in computer, peripheral devices such as printers, input devices, and hard disk drives (HDDs) are also becoming more sophisticated. The computer and peripheral devices are connected by a communication cable or the like according to a predetermined communication standard. Many communication standards have been proposed and spread with the advancement of functionality, but in recent years, peripheral device connection methods based on the USB standard have been widely used.

  As interface standards, USB 1.0, USB 1.1, and USB 2.0 are announced in order, and the connector transmission rate according to the USB 1.0 standard is 1.5 Mpbs, and the connector transmission according to the USB 1.1 standard. The rate of transmission is 12 Mpbs, and the transmission rate of the connector according to the USB 2.0 standard is 480 Mpbs. Now, the connector according to the USB 2.0 standard is now used so as to be widely used in the electronic industry.

  According to the development of the electronic industry, the transmission speed of the connector according to the USB 2.0 standard does not satisfy the demand for development. For example, when transmitting music and movies, the transmission speed reaches 1 Gpbs or more. The use of the 0 standard connector is limited because it cannot satisfy the use requirement of the transmission speed. Now, when transmitting music and movies, connectors such as the Serial-ATA standard that can transmit at high speed are always used. However, in terms of applications, USB standard connectors are wider than Serial-ATA standard connectors. Further, since the volume of the USB standard connector is smaller, it is advantageous for the development of miniaturization in the electronic industry. Therefore, it is necessary to develop a new type socket connector that can perform high-speed transmission based on the USB standard.

  It is an object of the present invention to provide a socket connector with improved transmission speed and easy manufacturing.

The structure and arrangement method of the first terminal 31 conforms to the USB standard. Specifically, the first terminal 31 includes a power supply terminal 311, a pair of differential signal terminals 312, and a first ground terminal 313. The pair of differential signal terminals 312 is disposed between the power supply terminal 311 and the first ground terminal 131.

  The second terminal 32 has the same structure, the flat plate-like second contact portion 36, the second tail portion 38 for connecting to the circuit board, and the second contact portion 36 and the second tail portion 38 for connecting them. A second holding portion 37, the second contact portion 36 is received in the second receiving groove 124 of the first base portion 11, and the second holding portion 37 is bent and extends from the second contact portion 36. As described above, the bent portion (without reference symbol) accommodated in the concave groove 126 and the third accommodating groove 125 are folded so as to extend in parallel with the second contact portion 36. Part. The second terminal 32 has two pairs of differential signal terminals 321 and one second ground terminal 322, and one second ground terminal 322 is disposed between the two pairs of differential signal terminals 321. This reduces noise. Since the cover 15 is combined with the first base 11 after the second terminal 32 is attached to the first insulating body 1, the assembly method of the second terminal 32 is simplified and the deformation of the second terminal 32 occurs. It becomes difficult.

  The second insulating body 2 includes a second base 21 and a second tongue piece 22 formed to extend forward from the second base 21, and a second accommodation space 24 at the rear end of the second base 21. Guide protrusions 215 are formed on both sides of the top wall of the second base 21, and a receiving portion 214 for receiving the holding member 114 is formed between the guide protrusions 215. When the holding member 114 interferes with and engages with the receiving portion 214, the holding member 114 is integrally combined with the first insulating body 1 and the second insulating body 2. The structure of the second tongue piece 22 is the same as that of the first tongue piece 12, the second conductive terminal set 4 is attached to the second tongue piece 22, and the structure and arrangement method thereof are the same as those of the first terminal set 3. Not described in detail.

  The base 8 is assembled in the first accommodation space 14 and the second accommodation space 24, and terminal holes 82 for positioning the first conductive terminal set 3 and the second conductive terminal set 4 are formed to correspond to each other.

  The outer shield 6 includes a top plate 65, a bottom plate 66, and left and right side plates 67 that cover the combined first insulating body 1 and second insulating body 2 and are provided with a first elastic piece 61, respectively. Each of the left and right side plates 67 has an engagement hole 62 formed at the front end, and an engagement groove 63 for engaging with the convex rib 113 of the first insulating body 1 at the rear end. A locking groove 64 is formed below 63.

  The inner shield 5 covers the spacing plate 13 of the first insulating body 1 and is provided with a top plate 53 and a bottom plate 54 on which the second elastic piece 51 is provided. Engagement pieces 52 for engagement are formed respectively.

  The socket connector 100 has two pairs of differential signal terminals 321 and one ground terminal 322, and the first tongue plate 12 has a conventional dimension compared to a conventional socket connector (not shown) based on the USB standard. Since it is almost the same as the tongue plate of the socket connector based on the USB standard, the conventional plug connector 200 (shown in FIG. 9) based on the USB standard can be fitted, and the contact portion 36 of the second terminal 32 has a flat plate shape. Since it is completely accommodated in the second accommodating groove 124, it does not contact the conductive terminal 207 of the conventional plug connector 200 so as to rub.

  A first insertion port 10 is formed between the top plate 53 of the inner shield 5 and the top plate 65 of the outer shield, and a second insertion port 20 is formed between the bottom plate 54 of the inner shield 5 and the outer shield 66.

The first terminal 503 is electrically and mechanically connected, and the second terminal 32 is electrically and mechanically connected to the second terminal 502 of the plug connector 500. By increasing the two pairs of differential signal terminals 321, the transmission speed is improved. The interface standard of the second insertion slot 20 is completely the same as that of the first insertion slot 10. Of course, in other implementation states, the interface standard of the second insertion slot is different from that of the first insertion slot. For example, the interface standard of the second insertion slot 20 ′ of the socket connector 100 ′ shown in FIG. 8 is Serial ATA. It is a standard.

  Since the first insulating main body 1 and the second insulating main body 2 are separated bodies, the mold becomes simple and the manufacturing process becomes easy.
