Embodiment Construction

[0025] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0026] Embodiments of the connector of the present invention: as figure 1 As shown, the connector housing 1 is included. The connector housing 1 is a rectangular housing with a relatively large aspect ratio. A large number of installation structures are arranged in the connector housing 1 along its length direction to provide signal contact parts 3 respectively. Install with ground shield 4. The signal contact parts 3 and the ground shielding sheet 4 are arranged side by side along the length direction of the connector housing, and the ground shielding sheet 4 is interposed between every two signal contact parts 3 . A grounding plate 2 extending along its length is also installed in the connector housing 1, and card slots are arranged at intervals on the grounding plate 2. When the grounding plate 2 is installed in the connector housing 1, each card on ...

Abstract

The invention relates to the field of conductive connection, and particularly provides a connector and a shielding sheet. A plurality of signal contact parts are arranged side by side in the housing of the connector. A grounding shielding sheet covering the two signal contacts of the signal contact parts is clamped between every two signal contact parts. The grounding shielding sheet comprises a main sheet and an extension sheet which is perpendicular to the main sheet and extends along the arrangement direction of the signal contact parts. The extension sheet is located on the side of the main sheet close to the pin. Each signal contact part is provided with an escape groove for penetration of the extension sheet. The overhanging end of the extension sheet is provided with a contact partin electrical contact with the adjacent grounding shielding sheet. According to the connector, the contact part is arranged at the overhanging end of the extension sheet of the grounding shielding sheet so that electrical conduction between the two adjacent grounding shielding sheets can be realized, the grounding shielding sheets of the whole connector are shielded at the side of the differentialpair close to the pin, the anti-crosstalk effect can be improved and the transmission performance of the connector can be improved.

Description

technical field [0001] The invention relates to the field of conductive connection, in particular to a connector and a shielding sheet suitable for the connector. Background technique [0002] With the development of communication and information technology, the use of high-speed connectors for signal transmission is becoming more and more common. Taking card edge connectors as an example, there are a large number of densely arranged signal contact parts in the connector housing. The signal contacts of the signal contact part can form a differential pair. In order to avoid mutual crosstalk between differential pairs, every second signal contact part is provided with a shielding sheet. [0003] For example, the authorized announcement number is CN204577746U, and the utility model name is the connector disclosed in the Chinese Utility Model Patent of Electric Connector. Each signal contact part includes a rubber core, that is, an insulating block, and two opposite signal cont...
