Electrical Connector Terminal Layout for Higher Signal Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face limitations in high-frequency signal transmission due to limited space, which restricts the number of conductive terminals and fails to meet increasing market demands.
Innovation Solution
The electrical connector rearranges second terminals by having their elastic arms extend at an oblique angle to the first side edges, allowing for denser packing and increased signal transmission speed, while maintaining the arrangement of first terminals unchanged to reduce production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the elastic arm of second terminals extends parallel to first side edges (conventional arrangement), then the assembly method is simple and production cost is low, but the number of conductive terminals that can be accommodated is limited
Solution Approach 1:
The patent applies asymmetry by changing the elastic arm orientation of second terminals from parallel to oblique relative to the first side edges. This asymmetric arrangement allows second terminals to be densely packed in the second region while first terminals maintain their parallel arrangement in the first region, thereby increasing the total number of conductive terminals without uniformly complicating the entire structure
Solution Approach 2:
The patent divides the insulating body into two distinct regions: a first region where first terminals are arranged with elastic arms parallel to first side edges, and a second region where second terminals are arranged with elastic arms at oblique angles. This segmentation allows different arrangement strategies to be applied to different terminal groups, optimizing both density and manufacturability
2Quantity of substance
If more conductive terminals are arranged in limited space, then signal transmission requirements are met, but the arrangement complexity increases
Solution Approach 1:
The patent applies local quality by implementing different elastic arm orientations in different regions: first terminals in the first region maintain simple parallel arrangement for ease of assembly, while second terminals in the second region use oblique arrangement to achieve higher density. This localized differentiation optimizes each region's characteristics without requiring complete structural redesign

AI summary
An electrical connector includes an insulating body and conductive terminals. The insulating body has an upper surface and a lower surface provided opposite to each other along a vertical direction, two first side edges and two second side edges. The insulating body further has a first region and a second region. Each conductive terminal has an elastic arm and an abutting arm connected to the elastic arm. The conductive terminals include first terminals provided in the first region and second terminals provided in the second region. Viewing from a top view angle, the elastic arm of each first terminal extends along a first direction parallel to or perpendicular to the first side edges, and the elastic arm of each second terminal extends along a second direction forming an oblique angle with the first side edges. The first direction and the second direction are both perpendicular to the vertical direction.
