Description

high-speed connector

The invention relates to a high-speed connector, in particular to a high-speed connector that adjusts the dielectric coefficient of the structure around the terminal, changes the electromagnetic characteristics and crosstalk interference, and improves the quality of high-frequency signal transmission.

Existing high-speed connectors usually use ground lugs to connect several ground terminals to reduce insertion loss and crosstalk interference. Wherein, the existing grounding plate is composed of a sheet-shaped body and a plurality of elastic arms extending from the sheet-shaped body, and most of the elastic arms are integrally stamped with the sheet-shaped body in the form of a cantilever beam. 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 the existing grounding sheet still has room for further improvement, so as to improve the performance of the existing high-speed connector.

Taiwan Patent Certificate No. I635677 discloses "a high-speed connector and its transmission module", which includes a housing, an insulating rubber core inserted in the housing, a plurality of first conductive terminals and a plurality of first conductive terminals fixed on the insulating rubber core. Two conductive terminals, and a shield. 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 opposite outer sides of the two differential signal terminals. The shielding element includes a base material assembled on the casing and a metal plating layer plated on the base material, and the metal plating layer contacts the two ground terminals so as to electrically connect the two ground terminals. Metal plating on two opposite two outer sides of the differential signal terminals, so that the metal plating layer can shield the two differential signal terminals in the width direction.

However, the whole surface of the above-mentioned high-speed connector is covered with metal coating to achieve shielding effect. The disadvantage of this design is that the signal will easily cause oscillation reflection when it hits the metal coating. This oscillation will generate many resonance points. When the high-speed connector transmits signals at higher speeds On the contrary, it will make its high frequency characteristics worse. When high-frequency signals are transmitted between adjacent terminals, it is difficult to avoid crosstalk interference. However, the above-mentioned high-speed connectors are covered with metal plating, which deteriorates high-frequency characteristics and affects the crosstalk effect.

Therefore, it is necessary to provide an electrical connector that can adjust the dielectric coefficient of the structure around the terminal, change the electromagnetic characteristics and crosstalk interference, and improve the quality of high-frequency signal transmission.
