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 specifically provides a connector and a shielding sheet. A plurality of signal contact parts are arranged side by side in the housing of the connector, and a ground shield sheet covering the two signal contact parts of the signal contact parts is sandwiched between each two signal contact parts. The ground shield sheet includes a main sheet body and a The extension sheet extends along the arrangement direction of the signal contact parts from the main sheet body. The overhanging end of the sheet has a contact portion that electrically contacts an adjacent ground shield sheet. The connector of the present invention can realize the electrical conduction between two adjacent ground shielding pieces by setting the contact portion at the overhanging end of the extension piece of the grounding shielding piece, so that the grounding shielding piece of the whole connector is in the differential pair. The side close to the pin is shielded, which improves the effect of anti-crosstalk and improves the transmission performance of the connector.

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...
