Differential connector with special-shaped conductive structure and manufacturing method of differential connector

Abstract

The invention discloses a differential connector with a special-shaped conductive structure and a manufacturing method of the differential connector. The differential connector comprises a mounting mechanism, a plurality of groups of differential conductive parts are installed in the mounting mechanism, and each differential conductive part comprises grounding sheets and differential signal sheets. A protection structure is mounted outside the mounting mechanism. The inner wall of the protection structure is provided with continuous and compact conductive coatings. The differential signal sheets and the conductive coatings are arranged at intervals, the grounding sheets are electrically connected with the conductive coatings, and the conductive coatings are used for forming a continuous anti-crosstalk structure outside the differential signal sheets. The outer protective layer of the differential connector is manufactured by adopting a mode of spraying the conductive coatings, and the differential connector can be processed into any shape and size, so that the processing cost of the differential connector is lower, and the processing is more convenient.

Description

technical field [0001] The invention belongs to the technical field of high-speed transmission connectors, in particular to a differential connector with a special-shaped conductive structure and a manufacturing method thereof. Background technique [0002] The differential signal connector is a special multi-conductor connector, which refers to a pair of coupled transmission lines; the transmission line of the differential signal uses two transmission drivers to drive two transmission lines, one transmits signals, and the other is complementary signal, and the real effective signal is the voltage difference on the differential pair. Only two transmission lines are needed to form a differential pair; [0003] Differential conductors must be properly routed in order to optimize the transmission performance of differential signals. Therefore, the shape of differential conductors is complex and consists of multiple turning structures; when manufacturing connectors, since diffe...

Problems solved by technology

[0004] However, it is very difficult to process the metal conductor into a multi-segment turning outer protective layer. The shape that the metal conductor can be processed is limited, which also limits the degree of optimization of the transmission performance. Each outer protective layer can only correspond to a differential conductor in one direction. , which makes the processing cost high and affects the signal transmission effect
