Electrical Connector Terminals With Extending Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrical connectors have a small volume and surface area, which limits their high-frequency performance.
Innovation Solution
The electrical connector design includes an insulating body with terminals that feature a conductive portion, a connecting portion, an elastic arm, and extending arms with free tail ends that form a tubular structure and an electrical connecting portion, increasing the terminal's volume and surface area to reduce impedance and improve high-frequency performance.

Engineering Contradiction Analysis
1Reliability
If the terminal volume and surface area are increased to improve high-frequency performance, then the impedance is reduced and high-frequency performance is improved, but the device complexity increases
Solution Approach 1:
The terminal is divided into multiple functional segments: connecting portion, elastic arm, extending arms, and electrical connecting portion. Each segment serves a specific function, allowing the terminal to achieve increased volume and surface area while maintaining manageable structural complexity through modular design.
Solution Approach 2:
The terminal structure transitions from a conventional planar design to a three-dimensional configuration with extending arms that protrude laterally from the insulating body. This dimensional change increases the surface area and volume of the terminal, improving high-frequency performance without significantly increasing overall device complexity.
2Volume of stationary object
If the terminal volume is increased by adding extending arms, then the impedance is reduced, but the manufacturing complexity increases
Solution Approach 1:
The extending arms are integrated with the insulating body as a unified structure, where the arms extend laterally from the body and are positioned to abut the walls of the terminal groove. This merging of components simplifies manufacturing by reducing the number of separate parts that need to be assembled.
Solution Approach 2:
The extending arms serve multiple functions: they increase the terminal volume for improved high-frequency performance, provide mechanical support by abutting the terminal groove walls, and facilitate electrical connection. This multi-functionality reduces manufacturing complexity by eliminating the need for separate components for each function.

AI summary
An electrical connector mounted on a circuit board and used to be electrically connected to an electrical module includes an insulating body, and multiple terminals provided on the insulating body. At least one of the terminals has: a connecting portion; an elastic arm, bending and extending upward from the connecting portion for being electrically connected to the electrical module; two extending arms, extending from the connecting portion, each of the two extending arms having a free tail end; and an electrical connecting portion, located at one of the free tail ends of the two extending arms for electrically connecting the two extending arms, and for increasing the volume and surface area of the terminal, so as to reduce impedance and improve high frequency thereof.
