Problems solved by technology

Often, the spacing between signal contacts is so small that undesired interference, or "crosstalk," occurs between adjacent signal contacts
Cross talk occurs when a signal in a single signal contact induces electrical interference in adjacent signal contacts due to interfering electric fields, thus compromising signal integrity
Crosstalk distortion can also occur between differential signal pairs
As the distance between interfering signal contacts decreases, crosstalk distortion will increase

Embodiment Construction

[0060] Existing differential signal connectors, such as Serial Advanced Technology Attachment (SATA), Serial Attached Small Computer System Interface (SCSI) (SAS), back panel (back panel), and mezzanine connectors (mezzanine connectors), their Electrical performance can be improved by electrically connecting the ground contacts inside the connector. The embodiments described herein allow simple retrofitting of existing connectors intended to operate at slower data transfer rates to yield drop-in compatible, higher data transfer rate connectors, This also complies with new development standards such as SATA Revision 2.6, SAS-2 Revision 15, IEEE 802.3ap, etc. More specifically, embodiments described herein can extend existing operating frequency ranges by shifting the resonant frequency of existing connectors without changing the dimensions of the mating or assembly interface dimensions of existing standardized or non-standardized connectors. In other words, the described embod...

Abstract

Example electpcal connectors are provided including a plurality of electrical contacts configured to communicate between electrical devices. The plurality of electrical contacts includes a plurality of ground contacts. A ground coupling assembly is configured to electrically connect ground contacts of an electrical connector to adjust a performance characteristic of the electrical connector as desired.

Description

technical field [0001] In general, the present invention relates to the field of electrical connectors, and in particular to high-speed electrical connectors, including an insulating housing module with a plurality of contacts. The present invention further relates to a connector, which comprises a plurality of the above insulating shell modules. Background technique [0002] Electrical connectors provide signal connections between electronic devices using signal contacts. Often, the spacing between signal contacts is so small that undesired interference, or "crosstalk," occurs between adjacent signal contacts. Cross talk occurs when a signal in a single signal contact induces electrical interference in adjacent signal contacts due to interfering electric fields, thus compromising the integrity of the signal. Crosstalk distortion can also occur between differential signal pairs. As the distance between interfering signal contacts decreases, crosstalk distortion will incre...
