Floating Contact Connector Structure for High-Frequency Signal Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors suffer from signal interference and unstable high-frequency characteristics due to the design of the contact and conducting portions, which lead to inefficient signal transmission between chip modules and circuit boards.
Innovation Solution
The electrical connector features a floating contact portion connected to the conducting portion through an insulating block, allowing the elastic arm to provide a force that ensures direct electrical connection, reducing signal interference and improving high-frequency characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the contact portion is connected to the elastic arm, then the terminal structure is simple and easy to manufacture, but the signals will diffuse to the surrounding elastic arm causing signal interferences to adjacent terminals
Solution Approach 1:
An insulating block is introduced as an intermediary component between the contact portion and the elastic arm. The insulating block electrically isolates the contact portion from the elastic arm, preventing signal diffusion to adjacent terminals while maintaining the structural simplicity of the terminal assembly.
Solution Approach 2:
The terminal is segmented into distinct functional parts: the contact portion, the insulating block, and the elastic arm. This segmentation allows each component to perform its specific function independently, with the insulating block preventing unwanted electrical coupling between the contact portion and elastic arm.
2Reliability
If the contact portion is pressed to deviate for contact with the conductor, then the terminal can establish electrical connection, but the contact becomes unstable affecting signal transmission
Solution Approach 1:
The insulating block serves as a stable intermediary that supports the contact portion in a fixed position relative to the conductor. This eliminates the need for the contact portion to deviate or press against the elastic arm for contact, providing stable and reliable electrical connection.
3Device complexity
If signals are transmitted through the elastic arm, then the terminal structure is simple, but the high frequency characteristics are degraded due to signal diffusion
Solution Approach 1:
The insulating block acts as an electrical barrier between the contact portion and the elastic arm, preventing high-frequency signals from diffusing into the elastic arm structure. This maintains good high-frequency characteristics while keeping the overall terminal structure relatively simple.
Solution Approach 2:
The insulating block provides localized electrical isolation only where needed at the contact portion, without requiring changes to the overall terminal structure or elastic arm design. This selective application of insulation preserves signal integrity at the critical interface.

AI summary
A method of manufacturing an electrical connector is provided. The method includes: providing a terminal and a strip, where the strip is connected to the terminal, and the terminal is formed with an elastic arm, a floating contact portion and a conducting portion; then, insert-molding an insulating block, such that the insulating block connects the elastic arm and the floating contact portion; separating the elastic arm and the floating contact portion; further cutting the strip to separate the terminal from the strip; and providing an insulating body, where the insulating body is formed with at least one accommodating slot running vertically therethrough, and inserting the terminal into the accommodating slot. When the electrical connector is mated, 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.
