Problems solved by technology

As a result, a part of the holding part is exposed in the groove, and other parts of the holding part are surrounded by the insulating block, so that the medium around the holding part is inconsistent, resulting in relatively poor impedance consistency of the holding part. Poor, not conducive to signal transmission

Abstract

The invention discloses an electric connector and a manufacturing method thereof, and the electric connector comprises two signal terminals which are arranged in a first direction and form a differential pair, wherein each signal terminal is provided with a contact part, a conductive connection part and a connection part for connecting the contact part and the conductive connection part; an insulating block which comprises at least one first injection molding piece and a second injection molding piece, wherein the first injection molding piece wraps the connecting part, the second injection molding piece wraps the connecting part and the first injection molding piece, and the insulating block completely wraps the connecting part; the first injection molding piece is provided with at least two injection molding blocks and at least one bridging part, the bridging part is connected with the two adjacent injection molding blocks, the bridging part and the two adjacent injection molding blocks jointly form two positioning notches, and each signal terminal is provided with at least one first mold fixing part; the positioning area of each primary mold fixing part is exposed to the corresponding positioning notch, and the bridging part covers a part of the primary mold fixing part. The impedance consistency of the signal terminal can be improved.

Description

【Technical field】 [0001] The invention relates to an electrical connector and a manufacturing method thereof, in particular to an electrical connector for improving the impedance consistency of signal terminals and a manufacturing method thereof. 【Background technique】 [0002] A conventional electrical connector includes a plurality of signal terminals, and insulating blocks attached around the holding portions of the signal terminals, so as to fix or isolate the holding portions of the signal terminals from the outside through the insulating blocks. The insulating block only includes an insulator that is injection-molded at one time. When the insulating block is injection-molded on the holding portion of the signal terminal, it is often necessary to clamp the signal terminal with a mold to fix the signal terminal. After the insulating block is formed and the mold is removed, the insulating block often leaves a groove at the position where the signal terminal is clamped by ...
