A shielding piece and a connector

Abstract

A shielding component and connector are disclosed. The shielding component includes a plate-shaped portion and a tubular portion, which are electrically connected to the plate-shaped portion. The tubular portion is used to absorb crosstalk electromagnetic waves around its periphery. The shielding component of this application absorbs and shields crosstalk electromagnetic waves between upper and lower rows of signal terminals through the electrically connected plate-shaped portion and tubular portion. In the thickness direction of the plate-shaped portion, since the size of the tubular portion is larger than the thickness of the plate-shaped portion, the spacing between the shielding component and the signal terminals can be reduced through the tubular portion, thereby enhancing the shielding effect of the shielding component against electromagnetic fields and efficiently absorbing crosstalk electromagnetic waves from the signal terminals, thus improving shielding effectiveness. This helps reduce the influence of external electromagnetic fields on signal transmission, ensuring signal accuracy and stability, thereby improving the high-frequency signal transmission capability of the connector.
