AI Technical Summary

Problems solved by technology

Ordinary high-speed products start from the structural design and manufacturing process of large volume, large step distance, and small batches; the technological parameters of emerging laser welding and ultrasonic welding are too sensitive or extremely sensitive compared to small step distance and high-density products. resulting in relatively poor stability and uniformity

Embodiment Construction

[0028] Such as figure 1 , figure 2 As shown, the present invention provides a high-speed transmission connector with light plugging force, including a housing 200, and a base fitting 900 is fitted on the housing 200; the base fitting 900 includes a plastic body 400, so The above-mentioned plastic body 400 is alternately plugged with the substrate assembly A500 and the substrate assembly B600; the differential signal conductors arranged on the substrate assembly A and B are misaligned by 0.3mm to reduce the facing area, thereby adjusting the mutual capacitance The substrate assembly A and B adjust the dielectric constant around the conductor through the design of the plastic structure, which can affect both the mutual inductance reactance and the mutual capacitive reactance; in short, the substrate assembly A500 and the substrate assembly B600 Alternately arranged to ensure impedance matching, optimize the characteristics of differential signals, such as phase difference, def...

Abstract

The invention relates to a high-speed transmission connector with low insertion force, belonging to the technical field of electric connectors. The connector comprises a shell, wherein a base assembly is assembled on the shell in an embedded manner and comprises a plastic body; substrate assemblies A and substrate assemblies B are alternately connected on the plastic body in an inserted manner; a shielding cover plate for restraining the base assembly is arranged at one side of the shell. The connector has the advantages that the base assembly and the shell are mechanically fixed by the shielding cover plate; the mechanical and electrical performances of the device do not lose design functions in harsh environments; the connector has obvious beneficial effects.

Description

technical field [0001] The invention relates to an electrical connector, in particular to a high-speed transmission connector with light plugging force and belongs to the technical field of electrical connectors. Background technique [0002] In the field of communication and data transmission, the speed of signal processing is required to be faster and higher, the density is higher and higher, and the reliability requirements are higher and higher, which requires correspondingly higher requirements for connectors for functional module interconnection and subsystem interconnection , where the consistency of quality requirements bear the brunt. [0003] Engineering assurance of quality reliability and uniformity (DFM design for manufacturability, or design based on manufacturing feasibility, or structural design with easy manufacturing considerations) often represents the design level, manufacturing process level, and reflects the comprehensive scientific and technological ca...
