Abstract

The invention discloses an electric connector which comprises at least one terminal assembly, the terminal assembly comprises a first signal terminal and a second signal terminal, the first signal terminal and the second signal terminal are arranged to form a pair of differential terminals and are in narrow-side coupling, and the length of the first signal terminal is larger than that of the second signal terminal; the insulating block is used for fixing the first signal terminal and the second signal terminal; wherein a first connecting part of the first signal terminal is provided with at least one exposing area, the exposing area is exposed on the insulating block and exposed on the air medium, the first connecting part is provided with at least one widened part and at least one narrow part which are mutually connected along the length direction of the first connecting part, the width of the widened part is greater than that of the narrow part, and the exposing area is arranged on the widened part; and the second connecting part of the second signal terminal is completely wrapped in the insulating block. According to the invention, the signal transmission time lag can be improved, the impedance characteristic of the first signal terminal is balanced, and the forming difficulty and the signal coupling of the first signal terminal and the second signal terminal are less influenced.

Description

【Technical field】 [0001] The invention relates to an electrical connector, in particular to an electrical connector capable of improving signal transmission time lag. 【Background technique】 [0002] A known electrical connector includes multiple pairs of differential signal terminals arranged in a row along the vertical direction, and each pair of differential signal terminals includes a first signal terminal and a second signal terminal arranged along the vertical direction and coupled with narrow sides, Each of the first signal terminal and the second signal terminal includes a contact portion for electrically connecting with the mating connector, a lead portion mounted on a circuit board, and connected between the contact portion and the lead A connecting part between the parts, the extending directions of the contact part and the connecting part are perpendicular to each other. [0003] In the electrical connector, the lengths of the first signal terminal and the second...
