Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the number of terminal groups is increased to improve data transmission speed, then data transmission efficiency is improved, but device complexity increases
Solution Approach 1:
The connector is divided into multiple terminal groups (first terminal group with first and second conductive terminals, second terminal group with third and fourth conductive terminals), each group independently arranged within the insulating body. This segmentation allows increased data transmission capacity while maintaining organized structure
Solution Approach 2:
The terminal groups are arranged in a multi-dimensional configuration within the insulating body, with conductive terminals positioned at different locations and orientations. The first and second conductive terminals are arranged along a first direction, while the third and fourth conductive terminals are arranged along a second direction perpendicular to the first direction, maximizing space utilization
2Reliability
If multiple terminal groups with elastic arms are added to increase contact points, then data transmission efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
Multiple conductive terminals are integrated into a single insulating body structure, with each terminal group comprising multiple conductive terminals (first and second in one group, third and fourth in another group) that are manufactured as an integrated assembly, reducing the number of separate components
Solution Approach 2:
The conductive terminals are designed with elastic arms that can deform elastically during insertion and mating operations. This elasticity provides automatic contact adjustment and compensation for manufacturing tolerances, improving contact reliability without requiring high-precision manufacturing
3Productivity
If symmetric notches are added to the insulating body to accommodate terminal groups, then data transmission speed is improved, but device complexity increases
Solution Approach 1:
The insulating body features a symmetric structure with a first notch and a second notch positioned symmetrically on opposite sides of a central axis. This symmetric design provides balanced mechanical support for the terminal groups while maintaining manufacturing simplicity through repetitive patterns
Solution Approach 2:
The notches in the insulating body serve multiple functions: they provide structural support for the conductive terminals, create mating interfaces for the connector assembly, and facilitate the integration of multiple terminal groups within a compact form factor

AI summary
An electrical connector includes an insulating body and a number of terminal groups. The insulating body includes a mating slot, a first notch and a second notch. The first notch and the second notch are symmetrically arranged on opposite sides of the mating slot. The terminal groups include a first conductive terminal, a second conductive terminal, a third conductive terminal and a fourth conductive terminal. Each conductive terminals includes a mating portion extending into the mating slot. With this arrangement, relatively more terminal groups can be provided, which is beneficial to improve the speed of data transmission. A connector assembly having the electrical connector is also disclosed.
