Description

TECHNICAL FIELD

[0001] The present application relates to a high-speed connector, and more particularly to a high-speed connector capable of adjusting the dielectric coefficient of the structure around the terminal, changing the electromagnetic characteristics and crosstalk interference, and improving the quality of high-frequency signal transmission. BACKGROUND

[0002] The existing high-speed connector usually connects several ground terminals with a grounding sheet to reduce insertion loss and crosstalk interference. The existing grounding sheet is composed of a sheet-shaped body and a plurality of elastic arms extending from the sheet-shaped body, and the elastic arms are mostly formed in the form of a cantilever beam integrally punched with the sheet-shaped body. However, the structural strength of the existing grounding sheet is not high, and the existing grounding sheet cannot shield the differential signal terminals of the high-speed connector, so there is still room for improvement in the existing grounding sheet to improve the performance of the existing high-speed connector.

[0003] Taiwanese Patent No. I635677 discloses a "high-speed connector and transmission module thereof", which includes a housing, an insulating core inserted into the housing, a plurality of first conductive terminals and a plurality of second conductive terminals fixed to the insulating core, and a shielding member. The plurality of first conductive terminals are arranged along the width direction and include two differential signal terminals and two ground terminals respectively located on the opposite two outer sides of the two differential signal terminals. The shielding member includes a base material assembled to the housing and a metal plating layer plated on the base material, and the metal plating layer contacts the two ground terminals to electrically connect the two ground terminals. The metal plating layer is located on the opposite two outer sides of the two differential signal terminals, so that the metal plating layer can shield the two differential signal terminals in the width direction.

[0004] However, the entire surface of the above-mentioned high-speed connector is covered with a metal plating layer to achieve shielding effect. The disadvantage of this design is that the signal will easily cause oscillation reflection when it encounters the metal plating layer. The oscillation will generate many resonance points, which will make the high-frequency characteristics of the high-speed connector worse when it transmits higher speed signals. High-frequency signal transmission between adjacent terminals is difficult to avoid the generation of crosstalk interference. However, the above-mentioned high-speed connector covers the entire surface with a metal plating layer, which makes the high-frequency characteristics worse and affects the crosstalk effect.

[0005] Therefore, it is necessary to provide an electrical connector capable of adjusting the dielectric coefficient of the structure around the terminal, changing the electromagnetic characteristics and crosstalk interference, and improving the quality of high-frequency signal transmission.
