Electrical Connector Terminals with Through Slot for Ultra-Thin Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors with conductive terminals have relatively great heights due to the need for long elastic arms to ensure good contact, which hinders the ultra-thinning of the connector.
Innovation Solution
The electrical connector design features conductive terminals with flat plate portions that are vertically movably limited in accommodating holes, where a through slot extends from the upper elastic arm through the flat plate portion to the lower elastic arm, allowing for reduced arm lengths while maintaining elasticity, and includes position limiting protrusions to prevent vertical and rearward movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the upper elastic arm and lower elastic arm are made relatively long to ensure elasticity and good contact, then the contact reliability is improved, but the height of the conductive terminal increases
Solution Approach 1:
The conductive terminal is divided into three main segments: the flat plate portion, the upper elastic arm, and the lower elastic arm. The through slot further segments the flat plate portion, allowing independent deformation zones that enable shorter arm lengths while maintaining overall elasticity. This segmentation allows each part to be optimized for its specific function without requiring excessive length.
Solution Approach 2:
The invention changes the structural parameters of the conductive terminal by introducing a through slot that extends through the flat plate portion. This parameter change enables the elastic arms to be shorter while still achieving the required elasticity, as the through slot creates additional flexibility in the flat plate portion that compensates for the reduced arm length.
2Length of moving object
If the through slot extends through the flat plate portion to reduce terminal height, then the elasticity is enhanced and height is reduced, but the structural complexity increases
Solution Approach 1:
The through slot segments the flat plate portion into two separate sections, creating a more complex but functional structure. This segmentation allows the flat plate to deform more effectively, providing the necessary elasticity with shorter arm lengths. The position limiting portions further segment the movement control, allowing precise limitation without excessive complexity.
Solution Approach 2:
Instead of making the elastic arms long to achieve elasticity, the invention inverts the approach by creating elasticity through the through slot in the flat plate portion. This inversion allows the arms to be short while still achieving the desired elastic behavior through the slot-induced flexibility.
3Stability of the object's composition
If position limiting portions protrude into the accommodating hole to prevent vertical movement, then the position stability is improved, but the risk of damage to the body during assembly increases
Solution Approach 1:
The position limiting portions are designed with specific dimensional parameters that allow them to protrude into the accommodating hole enough to provide stable positioning while maintaining sufficient clearance to avoid damaging the body during assembly. The through slot dimensions and position limiting portion dimensions are carefully balanced to achieve this optimization.
Solution Approach 2:
The design inherently provides cushioning by allowing controlled deformation of the flat plate portion through the through slot before the position limiting portions contact the body. This prior cushioning effect reduces impact forces during assembly, preventing damage while still achieving stable positioning.

AI summary
An electrical connector includes a body having multiple accommodating holes running vertically therethrough, and multiple conductive terminals vertically movably accommodated in the accommodating holes. Each accommodating hole has upper and lower position limiting surfaces. Each conductive terminal includes a flat plate portion having an upper position limiting portion located above the upper position limiting surface, and a lower position limiting portion located below the lower position limiting surface, so as to limit a vertical movement of the conductive terminal. Upper and lower elastic arms are formed at a rear side the flat plate portion. Each of the upper and lower elastic arms has a corresponding contact portion to correspondingly abut a first electronic component and a second electronic component. A through slot extends from the upper elastic arm through the flat plate portion to the lower elastic arm.
