PCB connector with variable capacity and adjustable space

Abstract

The invention discloses a PCB connector with variable capacity and adjustable spacing, consisting of an upper difference transmission pair component (1), a lower difference transmission pair component (2), an upper lead rail support (3) and a lower lead rail support (4); wherein, a plurality of plug ends of the upper difference transmission pair component (1) are respectively inserted and connected on a plurality of plug clips of the lower difference transmission pair component (2) to realize electrical signal connection; the upper difference transmission pair component (1) is assembled on the upper lead rail support (3), and the lower difference transmission pair component (2) is assembled on the lower lead rail support (4); the installation of the upper lead rail support (3) and the lower lead rail support (4) is realized by the cooperation between a fixture block (410) and a neck (312). The connector adopts a plurality of groups of apposable upper power strips to form the upper difference transmission pair component, and makes a plurality of copper bars and insulation materials into an upper power strip by adopting the pouring technique; the lower difference transmission pair component is formed by a plurality of groups of apposable lower power strips, and a lower power strip is manufactured by a plurality of copper bars and insulation materials by the pouring technique; the upper power strips and the lower power strips are connected with the plug ends by using the plug clips, thus realizing the signal transmission from a PCB backing plate to a PCB.

Description

technical field [0001] The invention relates to a workpiece for electrical connection and assembly, more particularly, a PCB connector with variable capacity and adjustable spacing applied to PCB circuit board assembly. Background technique [0002] In electronic systems, electrical connectors are the necessary components to form electrical connections between devices and components, components and components, and subsystems to form a complete system. Electrical connectors provide signal connections between electronic devices using signal contacts. Often, the signal contacts are spaced so closely that undesired interference or crosstalk occurs between adjacent signal contacts. Traditional high-speed connectors generally use stripline or microstrip design. This structure usually adds a metal shielding layer on one or both sides of the differential pair to control the differential impedance and crosstalk between the signal pairs. Part of the signal integrity problem can be ...

AI Technical Summary

Problems solved by technology

Part of the signal integrity problem can be eliminated by adding a metal shielding layer, but at the same time it will increase the manufacturing cost of the connector and increase the weight of the connector (not suitable for miniaturized applications), and the distance between the shielding layer and the signal pair The spatial layout will also have a certain impact on controlling the differential impedance
