Electrical Connector Insulating Support for Terminal Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face challenges in preventing chip modules from excessively pressing conductive terminals, which can lead to damage, especially as electronic components become smaller and more densely packed, making it difficult to arrange protrusions for protection.
Innovation Solution
The design incorporates a metal connecting portion with an insulating supporting portion on the insulating body that abuts the chip module upward, preventing excessive pressing and potential damage to the terminals, while maintaining a compact and efficient layout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protrusion is arranged on the insulating body to prevent excessive pressing, then the terminals are protected from damage, but the device complexity increases and the available space decreases
Solution Approach 1:
The patent combines the protective function with the existing insulating body structure by forming the protrusion as an integrated feature of the insulating body rather than as a separate component. This merging approach maintains terminal protection while avoiding additional parts and assembly steps, thus not increasing device complexity.
Solution Approach 2:
The protrusion structure serves multiple functions: it acts as a mechanical stop to prevent excessive pressing of terminals, provides structural support for the insulating body, and helps define the positioning of the chip module. This multi-functionality reduces the need for separate protective components.
2Volume of moving object
If the size and height of the electrical connector are reduced, then the product becomes more compact, but the space for arranging protective protrusions becomes smaller
Solution Approach 1:
The patent utilizes the vertical dimension by designing the protrusion to extend upward from the insulating body surface. This vertical arrangement allows the protective feature to be implemented without occupying additional horizontal space, enabling compact connector designs while maintaining protection functionality.
Solution Approach 2:
The protrusion is nested within or integrated into the insulating body structure rather than being an external addition. This nesting approach allows the protective feature to be accommodated within the existing volume of the connector, maintaining compact dimensions while providing protection.

Function Achieved in This Case
This solution effectively prevents the chip module from excessively pressing the terminals, thereby protecting them from damage, and allows for a more stable and secure electrical connection without occupying additional space.
Implementation Method 1
the insulating supporting portion is configured to abut the chip module upward
Implementation Method 2
the conductive terminals generate elastic deformation and then make abutting contacts with the contact pads of the chip module through the elastic forces of the conductive terminals

AI summary
An electrical connector is used to be electrically connected with a chip module having multiple contact pads. The electrical connector includes an insulating body, provided with multiple accommodating grooves. Multiple terminals are accommodated in the accommodating grooves respectively. Each terminal has a main body portion located in a corresponding accommodating groove. An extending arm is connected with one end of the main body portion, and is used to be electrically connected with one of the contact pads upward. At least one metal connecting portion is provided on the insulating body and located at one side of the extending arm. One end of the metal connecting portion has an insulating supporting portion. The insulating supporting portion is used to abut the chip module upward, and is not in contact with or not electrically connected with the contact pads.
