Description

Technical Field

[0001] The utility model relates to a shielding connection component, comprising a connector of the shielding connection component and a connector component comprising the connector. Background Art

[0002] In the prior art, the operating environment of connector products is becoming more and more harsh, and the transmitted signals are easily interfered by the surrounding electromagnetic signals. The equipment has higher and higher requirements for the anti-interference ability of the products, requiring the connector products to have a reliable shielding function, such as requiring the shielding contact impedance of the connector products to be lower than 100mΩ. In the prior art, the electrical connection between the two shielding parts is achieved by axially compressing the wave spring. Due to the accumulation of manufacturing and assembly tolerances and structural limitations, the shielding part is required to be able to adapt to the spacing of 0.50 to 1.38 and provide a reliable connection with low impedance. However, the existing connector products use ordinary wave springs for shielding connection, which cannot effectively adapt to the change of 0.50 to 1.38mm spacing. In terms of design, it only uses axial electrical contact, which cannot meet the requirement of shielding contact impedance lower than 100mΩ. In addition, the existing wave spring is a closed rectangle. When it is axially compressed, the internal stress cannot be released, and it is easy to plastically deform, resulting in unreliable electrical contact. Utility Model Content
