Electrical Connector Terminal Adjusting Portion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors experience signal interference due to electromagnetic waves from signal conductors, leading to reduced signal transmission efficiency and stability.
Innovation Solution
The electrical connector design includes an insulating body with a unique arrangement of terminals and ribs, where the adjusting portions of the terminals are positioned behind the insertion slot's bottom surface, reducing electromagnetic interference and enhancing signal transmission efficiency by using a medium with a lower dielectric coefficient between signal terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the back end of the first elastic arm portion is positioned close to the front relative to the bottom surface of the insertion slot, then the signal transmission path is shortened, but the interference electromagnetic wave from the signal conductors affects the signal transmission efficiency
Solution Approach 1:
The patent positions the adjusting portion of the terminal in the depth dimension (behind the bottom surface of the insertion slot) rather than only in the lateral dimension, creating spatial separation between the signal conductors and the terminal's adjusting portion to reduce electromagnetic interference while maintaining signal transmission efficiency
2Stability of the object's composition
If the impedance in the first fixing portion is higher than the impedance of the first elastic arm portion, then the structural stability is improved, but the signal attenuation increases
Solution Approach 1:
The patent introduces an adjusting portion with adjustable impedance parameters that can be tuned to match the impedance between the high-impedance fixing portion and the low-impedance elastic arm portion, thereby reducing signal attenuation while maintaining structural stability
3Loss of time
If the adjusting portion of each terminal is positioned in front of the fixing portion, then the signal transmission path is shortened, but the electromagnetic interference from signal conductors increases
Solution Approach 1:
The patent repositions the adjusting portion from the lateral dimension (in front of the fixing portion) to the depth dimension (behind the bottom surface), achieving electromagnetic isolation from signal conductors while maintaining acceptable signal transmission timing
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design effectively reduces signal interference, increases signal output efficiency, and maintains high-frequency signal transmission quality by minimizing electromagnetic wave impact on the signal terminals.
Implementation Method 1
the free end of the first rib is located between the two contact portions of one of the at least one pair of first signal terminals... reducing the signal interference electromagnetic wave effect
Implementation Method 2
a portion of each of the contact portions of the terminals provided on the first side wall protrudes inward relative to the first side surface into the insertion slot... a medium between the two adjusting portions of each of the at least one pair of first signal terminals is completely a first medium, and a dielectric coefficient of the first medium is less than a dielectric coefficient of the insulating body

AI summary
An electrical connector is used to electrically connect a first component and a second component, including: an insulating body, having an insertion slot for the first component to insert backward therein; multiple terminals, having at least one pair of first signal terminals. Each terminal has a contact portion and a tail portion provided in the front-rear direction. The contact portion is provided relatively in front of the bottom surface and protrudes into the insertion slot to be electrically connected to the first component. The tail portion is electrically connected to the second component. Each terminal further has a connecting portion located between the contact portion and the tail portion. An insulating block is used to fix the terminal. The connecting portion of each terminal extends forward from the front surface of the insulating block and passes beyond the bottom surface. A portion of the connecting portion of each terminals not passing forward beyond the bottom surface is defined as an adjusting portion. A medium between the two adjusting portions of each pair of first signal terminals is completely a first medium. A dielectric coefficient of the first medium is less than a dielectric coefficient of the insulating body.
