Electrical Connector Oblique Hole Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing integration level of electronic devices has led to smaller conductive terminals in electrical connectors, reducing their strength and elasticity, which can result in deformation during installation, necessitating larger receiving holes to prevent damage.
Innovation Solution
The electrical connector design features receiving holes with specific configurations, including first, second, and third hole portions, where the second and third hole portions are obliquely positioned relative to the X and Y axes, and the conductive terminals have elastic arms and holding parts that are embedded in these holes to prevent deformation and ensure stable fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the conductive terminals are made smaller to increase integration level, then the layout concentration increases, but the strength and elasticity of the conductive terminals are weakened
Solution Approach 1:
The receiving hole is divided into three distinct portions: a first hole portion, a second hole portion, and a third hole portion. The conductive terminal is segmented into a main part, an elastic arm, a connection part, and a holding part. Each segment serves a specific function in distributing stress and preventing deformation, allowing the terminal to be smaller while maintaining strength.
Solution Approach 2:
The second hole portion is positioned obliquely relative to the X and Y axes, introducing a three-dimensional orientation to the receiving hole structure. This spatial arrangement allows the conductive terminal to be embedded at an angle, distributing external forces more effectively across multiple dimensions and preventing deformation without increasing the terminal's cross-sectional size.

If the conductive terminals are made smaller to increase integration, then the elasticity is reduced, but the installation complexity increases
Solution Approach 1:
The conductive terminal is pre-formed with an elastic arm and holding part that are designed to fit into the three-portions receiving hole structure. The oblique positioning of the second hole portion is predetermined in the insulation body, so that during installation, the terminal automatically aligns and embeds into the correct orientation, eliminating the need for complex manual positioning or adjustment.

AI summary
An electrical connector includes an insulation body and conductive terminals. The insulation body defines receiving holes corresponding to the conductive terminals, respectively. Each receiving hole includes a first hole portion, a second hole portion and a third hole portion. Each conductive terminal includes a main part, an elastic arm, a connection part, and a holding part. Both the main part and the holding part are embedded in the second hole portion, and are obliquely positioned relative to the X axis of the insulation body. The first and third hole portions are located at two opposite sides of the main part. At least part of the elastic arm is located above the first hole portion.
