Floating-Contact Electrical Connector for Stable High-Frequency Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors suffer from signal interference and poor high-frequency characteristics due to the diffusion of signals through the elastic arm, and unstable signal transmission caused by the deviation of the contact and conducting portions.
Innovation Solution
The electrical connector design features an elastic arm and a floating contact portion at an interval, connected through an insulating block, allowing the floating contact portion to move vertically and directly connect with the conducting portion, preventing signal diffusion and ensuring stable transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the contact portion is connected to the elastic arm, then the electrical connector can be assembled, but signals diffuse to surrounding areas causing interference to adjacent terminals
Solution Approach 1:
The terminal is divided into separate functional portions: the contact portion (for signal reception), the conductor (for signal transmission), and the elastic arm (for mechanical connection). This segmentation isolates the signal path from the elastic arm, preventing signal diffusion to surrounding areas while maintaining assembly capability.
Solution Approach 2:
The conductor acts as an intermediary element between the contact portion and the elastic arm. It provides a dedicated signal transmission path that prevents direct coupling between the signal-bearing contact portion and the non-conductive elastic arm, thereby eliminating signal interference while maintaining structural connection.
2Adaptability or versatility
If the contact portion and conducting portion are pressed to deviate, then the elastic arm provides elastic force, but the contact becomes unstable affecting signal transmission
Solution Approach 1:
The terminal incorporates dynamic elements including the elastic arm that can deform to provide continuous contact force, and the floating contact portion that can move vertically to maintain stable electrical connection. This dynamic design allows the terminal to adapt to assembly variations while ensuring reliable signal transmission.
Solution Approach 2:
The terminal utilizes parameter changes in the form of elastic deformation of the elastic arm and vertical movement of the floating contact portion. These parameter changes enable the terminal to maintain stable contact under varying assembly conditions while providing necessary elastic force.

AI summary
An electrical connector includes an insulating body with multiple accommodating slots, and multiple terminals accommodated in the accommodating slots. Each terminal has an elastic arm, a floating contact portion and a conducting portion. The elastic arm and the floating contact portion are provided at an interval. One end of the elastic arm is connected with the floating contact portion through an insulating block. When each terminal is mated with a first electronic component and a second electronic component, the conducting portion is electrically connected to the first electronic component, the floating contact portion is electrically connected to the second electronic component, the elastic arm provides an elastic force such that the floating contact portion moves downward, and the floating contact portion and the conducting portion are directly electrically connected.
