Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrical connectors, in particular to a high-speed connector and an assembling method thereof. BACKGROUND

[0002] In the field of high-speed data transmission, high-speed connectors are key components for realizing stable signal interaction between devices, and their performance directly affects the running efficiency of the entire system. At present, most high-speed connectors on the market use insulating plastic shells and rely on shielding sheets or conductive plastics to achieve shielding functions to address electromagnetic interference problems during signal transmission. However, these existing structures have obvious limitations. For connectors using conductive plastic, the contact between the conductive plastic and the ground PIN is a squeezing contact, and it has almost no elasticity. In a certain temperature environment, the contact force of this contact structure will gradually fail due to thermal stress relaxation, and thus the high-speed transmission performance of the connector will gradually decrease over time. At the same time, the shielding effectiveness of conductive plastic is limited and cannot meet the stringent requirements of higher rate application scenarios for shielding performance. For connectors using shielding sheets, the shielding sheets are usually manufactured through a stamping process, and during the stamping process, small and large cavities will inevitably be produced, which will seriously affect the shielding effect and result in low shielding efficiency, unable to effectively block internal and external electromagnetic interference, and also unable to adapt to the demand of high-speed signal transmission.
