Description

Connector improved structure of connector

The present invention provides a terminal improved structure of a connector, in particular, a spatial distance between the first terminal disposed in the upper row and the second terminals in the lower row in the longitudinal, lateral, and diagonal directions. Reduce crosstalk between adjacent two differential signal pairs, thereby improving the integrity of high-speed signal transmission to meet the transmission speed requirements of the CAT5e specification.

According to the electronic connector, it is widely used in various communication devices. As the transmission and connection components of electronic signals, the connector sockets of common standard specifications include RJ-11 (telephone line socket) and RJ-45 (network route socket). , USB (universal serial bus), IEEE1394 (sequence bus), RF (wireless transmission) and Pin-header (distribution) and many other types.

In addition, Mobile Device has become a part of most people's lives, and most people also carry mobile electronic devices to various places to use the wired network to connect to the Internet. At this time, mobile electronic devices (for example, notebook computers) It is very convenient to have an RJ-45 network connector. General CAT5 network routes are commonly used for 100Mbps networks, such as 100BASE-TX (fast Ethernet). CAT5e is an enhanced version of CAT5 that requires a transfer speed of 125 Mbps and adds Far End Crosstalk. its It is required to follow the TIA/EIA-568-B standard, but the specifications are not much different from the CAT5 line, but the CAT5 network route or the CAT5e network route is only a basic data transmission line, and it must have good contact with the socket. To have good insulation between dense lines and lines, and the production cost can not be too high, it is hoped that the CAT5 line can be used more widely. Although the transmission speed requirement of the CAT5e network route is 125 Mbps, it is not the latest and fastest specification. However, in order to meet the transmission speed of this specification, the network connector connected to the network route must still have four internal differential signal pair terminals.
