Electrical Connector Terminals Misaligned Mounting Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face limitations in reducing the minimum distance between adjacent terminals due to interference from mounting portions and bending wings, restricting their close alignment.
Innovation Solution
The electrical connector design features terminals with mounting portions and bending wings arranged in misalignment, allowing for closer packing by shifting the mounting portions from the central axis and varying their heights, and utilizing guiding grooves and fixing pins for secure installation without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If electrical terminals are aligned densely to reduce distance, then packing density improves, but mounting portions and bending wings interfere with each other
Solution Approach 1:
The patent applies dimensionality change by arranging mounting portions in the vertical direction (altitude direction) rather than only in the horizontal plane. Specifically, first electrical terminals have mounting portions at a first altitude, while second electrical terminals have mounting portions at a second altitude different from the first. This vertical stacking approach allows horizontal dense alignment of terminal bodies while preventing interference between mounting portions through vertical separation.
Solution Approach 2:
The patent employs asymmetry in the positional arrangement of mounting portions relative to terminal bodies. The mounting portions are positioned at different altitudes depending on which lateral edge they are associated with, creating an asymmetric vertical distribution pattern. This asymmetric arrangement optimizes space utilization and prevents interference while maintaining dense horizontal packing.
2Power
If terminal bodies are made plate-shaped with bending wings for large-current transmission, then current transmission capability improves, but the thickness of mounting portions and bending wings increases minimum distance requirement
Solution Approach 1:
The patent resolves the space occupation problem of plate-shaped terminals with bending wings by utilizing the vertical dimension. Instead of expanding horizontally, the bending wings and mounting portions are arranged at different altitudes. This allows the terminal bodies to maintain their plate-shaped configuration for adequate current transmission while the vertical separation prevents horizontal space conflicts.
3Stability of the object's composition
If mounting portions are positioned centrally on terminal bodies, then structural symmetry is maintained, but interference with adjacent terminals occurs when densely packed
Solution Approach 1:
The patent deliberately introduces asymmetry in the vertical positioning of mounting portions to resolve the contradiction between symmetry and interference prevention. While terminal bodies maintain their symmetric plate-shaped structure, the mounting portions are positioned asymmetrically in the vertical direction - at different altitudes based on their association with different lateral edges. This asymmetric vertical arrangement eliminates interference while preserving the structural integrity of terminal bodies.

AI summary
An electrical connector includes a seat and two electrical terminals. The two electrical terminals are disposed within the seat. Each electrical terminal includes a terminal body and a mounting portion. Each terminal body includes a front end, a rear end, and two lateral edges opposite to each other. The two lateral edges are connected to the front end and the rear end. The mounting portion is extending from the rear end. The terminal body further includes one or more bending wings formed on one of the two lateral edges. The bending wing is located on an inner side of the terminal body. The inner sides of the terminal bodies face each other, and the terminal bodies of the two electrical terminals are arranged in parallel, and the mounting portions of the electrical terminals are located at different heights so as to be arranged in misalignment.
