Electrical Connector Terminal Retaining Portion Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors experience unstable connections between terminals and chip modules due to excessive shaking of the contact portion when subjected to external forces, leading to inconsistent electrical connections.
Innovation Solution
The design incorporates a retaining portion on the first base of the terminal, which is in interference fit with the insulating body, preventing excessive shake of the contact portion and ensuring stability by retaining the terminal within the accommodating slot.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the base is located far away from the contact portion and at the side of the main body portion, then the terminal structure is simplified, but the contact portion becomes unstable and shakes excessively when subjected to external forces
Solution Approach 1:
The base is folded at an angle (e.g., 90 degrees) relative to the main body portion, transitioning from a linear arrangement to a spatial configuration. This dimensional change allows the base to be positioned closer to the contact portion in three-dimensional space while maintaining structural simplicity, thereby stabilizing the contact portion without increasing terminal structure complexity
Solution Approach 2:
The base is divided into multiple segments or portions (first base portion, second base portion) connected by fold lines, allowing independent positioning of each segment. This segmentation enables the base to be optimally positioned near the contact portion for stability while keeping the overall terminal structure simple and manufacturable
2Ease of operation
If the main body portion is suspended without proper retention, then the terminal can be easily installed, but the contact portion shakes excessively and electrical connection becomes unstable
Solution Approach 1:
The base is pre-configured with a folded structure that creates preliminary resistance against external forces before they act on the contact portion. This pre-positioning of the base near the contact portion provides immediate structural support, preventing excessive shaking while maintaining easy installation through the folded configuration
Solution Approach 2:
The base is preliminarily positioned and fixed near the contact portion through the folded structure before the terminal is fully installed. This preliminary action ensures that the contact portion is already supported and stabilized during installation, preventing excessive shaking and ensuring reliable electrical connection from the outset

AI summary
An electrical connector is used for electrically connecting a chip module to a circuit board, and includes an insulating body provided with at least one accommodating slot, and at least one terminal provided in the at least one accommodating slot. The terminal has a first base and a second base formed by bending from the first base. An elastic arm is formed by bending upward and extending from the first base. The elastic arm is provided with a contact portion to be conductively connected with the chip module. The first base has a retaining portion located at a lower end thereof and extending downward. The retaining portion fits with the at least one accommodating slot to retain the terminal in the insulating body. A conducting portion extends downward from the second base to be conductively connected with the circuit board.
