Description

Electrical connector

Technical Field

The present invention relates to an electrical connector, and more particularly, to an electrical connector capable of improving transmission quality and stability.

Background

Electrical connectors refer to connecting elements and accessories for electrical signals. The electronic devices are connected to each other by cables and electrical connectors, i.e., the electrical connectors are also bridges between signals. Electrical connectors are widely used in automotive and computer peripheral applications for data communication applications, industrial, military aviation, transportation, consumer electronics, medical, instrumentation, commercial equipment, etc., and thus play an important role in a variety of fields. In the generation with advanced information and high efficiency, the transmission speed of signal is continuously increasing. Therefore, high frequency electrical connectors have also been developed to increase the transmission rate of signals.

A Serial attached SCSI connector (SAS connector) is one of the common connectors. SAS connectors are commonly used in computer peripherals such as hard disks, CD-ROMs, etc. for data transmission. Generally, an SAS connector includes 2 terminal sets, and each terminal set includes 2 signal differential terminal sets. Further, each terminal set includes ground terminals (usually 3) to separate the signal differential terminal sets, so as to avoid Crosstalk (Crosstalk) between the signal differential terminal sets.

As shown in fig. 1A and 1B, most of the terminals in the terminal group 91 of the currently marketed SAS electrical connector 9 are arranged in a double row. Although the ground terminal 913 in the terminal set 91 is located between the 2 differential

signal terminal sets

911 and 912, one of the signal terminals of the 2 differential

signal terminal sets

911 and 912 cannot be completely separated by the ground terminal. Further, when the terminals are arranged in double rows, the distance between each terminal is relatively short, and the terminals of the upper and lower rows may even partially overlap, so that the internal crosstalk phenomenon still exists in the terminal group of the current SAS connector. In addition, with the rapid development of the industry, the data transmission mode gradually moves to high frequency and high speed transmission, and the frequency of the signal carried by the SAS connector also increases. Therefore, the crosstalk of the SAS connector is more serious, and the quality, efficiency and stability of signal transmission are reduced.

Therefore, there is a need to improve the structure of the electrical connector to ensure the transmission efficiency and stability of the electrical connector.

As shown in fig. 2 to 5, in the present embodiment, the electrical connector 1 includes an insulative housing 10, a first terminal set 11, a second terminal set 12, and a third terminal set 13. The insulating housing 10 includes a through opening for the first terminal set 11, the second terminal set 12 and the third terminal set 13 to pass through and be disposed in the insulating housing 10.

The second signal terminal set 112 is used for transmitting differential signals and includes a third signal terminal 1121 and a fourth signal terminal 1122. The first ground terminal set 113 includes a first ground terminal 1131, a second ground terminal 1132 and a third ground terminal 1133, and the first ground terminal 1131, the second ground terminal 1132 and the third ground terminal 1133 are horizontally and parallelly arranged. The first signal terminal set 111 is vertically offset from the first ground terminal set 113 and is located between the first ground terminal 1131 and the second ground terminal 1132.

That is, the signal terminals of each signal terminal set are arranged at intervals in the vertical direction, except that the signal terminal set and the ground terminal set are arranged at intervals in the vertical direction.

In practice, the fourth ground terminal 1231, the fifth signal terminal 1211 and the sixth signal terminal 1212 may be sequentially arranged in a ladder-like manner, and the fifth ground terminal 1232, the seventh signal terminal 1221 and the eighth signal terminal 1222 may be sequentially arranged in a ladder-like manner. That is, all the adjacent terminals of the second terminal set 12 are not vertically overlapped and can be completely staggered, and the fifth ground terminal 1232 separates the third signal terminal set 121 and the fourth signal terminal set 122, so that the distance between the third signal terminal set 121 and the fourth signal terminal set 122 is relatively large, thereby preventing the third signal terminal set 121 and the fourth signal terminal set 122 from crosstalk, and further improving the signal transmission quality and stability.

Please refer to fig. 2 to 5 again.

In addition, since the lengths of the first signal terminal 1111 and the second signal terminal 1112 are the same, when the first signal terminal set 111 performs signal transmission, the voltage difference between the first signal terminal 1111 and the second signal terminal 1112 is 0, thereby improving the stability of signal transmission.

Similarly, the bent portion 115 of the third signal terminal 1121 may be bent upward and the bent portion 115 of the fourth signal terminal 1122 may be bent downward, so that the connection portion 116 of the third signal terminal 1121 and the fourth signal terminal 1122 can be received in the first terminal groove 1011.

In addition, since the lengths of the fifth signal terminal 1211 and the sixth signal terminal 1212 are the same, when the third signal terminal set 121 performs signal transmission, the voltage difference between the fifth signal terminal 1211 and the sixth signal terminal 1212 is 0, thereby improving the stability of signal transmission.
