Electrical Connector Air Gap and Segmented Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors experience increased resistance and insertion loss when transmitting high-frequency signals due to the design of signal terminals, which affects their performance.
Innovation Solution
The electrical connector features an insulating body with a gap space filled with air between two insulators, and terminals with narrower fixing segments and wider mating and positioning segments, reducing resistance and insertion loss by exposing the connecting segment to air and ensuring sufficient fixing height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the first section of the signal terminal is made slender to adjust impedance, then impedance matching is improved, but resistance increases and insertion loss increases
Solution Approach 1:
The terminal is divided into multiple sections with different widths: a first section for impedance matching, a second section with increased width to reduce resistance, and a third section for connection. This segmentation allows each section to optimize for its specific function, resolving the contradiction between impedance matching and resistance reduction.
Solution Approach 2:
Different sections of the terminal have different local qualities (widths) optimized for their specific functions. The first section has reduced width for impedance matching, while the second section has increased width for reduced resistance and lower insertion loss, allowing local optimization without compromising overall performance.
2Manufacturing precision
If the first section of the signal terminal is made longer to improve impedance matching, then impedance matching is improved, but resistance increases
Solution Approach 1:
The terminal structure is segmented into distinct sections where the first section provides the necessary length for impedance matching, while the second section compensates by providing additional width to reduce resistance, thus resolving the contradiction between length requirements for impedance and resistance considerations.
Solution Approach 2:
The terminal exhibits varying local qualities along its length, with the first section having reduced width for impedance control and the second section having increased width for reduced resistance, allowing the structure to meet both impedance matching requirements and resistance reduction goals simultaneously.

AI summary
An electrical connector includes an insulating body having a first insulator and a second insulator, and multiple terminals disposed on the insulating body. A gap space is formed between the first and second insulators. The gap space is filled with air. Each terminal has a mating segment located above the first insulator, a first fixing segment extending downward from the mating segment and insert-molded into the first insulator, a connecting segment extending downward from the first fixing segment and exposed to the gap space, a second fixing segment extending downward from the connecting segment and insert-molded into the second insulator, and a positioning segment extending downward from the second fixing segment and located below the second insulator. The width of the first and second fixing segment is less than the width of at least one of the mating segment, the connecting segment and the positioning segment.
