Abstract

An electrical connector is used to electrically connect a first component and a second component, including: an insulating body, having an insertion slot for the first component to insert backward therein; multiple terminals, having at least one pair of first signal terminals. Each terminal has a contact portion and a tail portion provided in the front-rear direction. The contact portion is provided relatively in front of the bottom surface and protrudes into the insertion slot to be electrically connected to the first component. The tail portion is electrically connected to the second component. Each terminal further has a connecting portion located between the contact portion and the tail portion. An insulating block is used to fix the terminal. The connecting portion of each terminal extends forward from the front surface of the insulating block and passes beyond the bottom surface. A portion of the connecting portion of each terminals not passing forward beyond the bottom surface is defined as an adjusting portion. A medium between the two adjusting portions of each pair of first signal terminals is completely a first medium. A dielectric coefficient of the first medium is less than a dielectric coefficient of the insulating body.

First claim
