Coaxial Connector Assembly With Sliding Insulator for Radial Offset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coaxial connectors face issues with plastic deformation of elastic cantilevers and increased volume due to significant radial deviations, which hinder miniaturization and reliable electrical contact.
Innovation Solution
A connector design featuring a sliding fit between upper and lower insulators and movably engaged outer conductors, allowing the upper insulator and outer conductor to rotate, which absorbs radial deviations and maintains electrical contact without excessive stress on elastic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the elastic cantilever and central terminal are offset to absorb radial deviation, then reliable electrical contact is ensured, but the elastic cantilever is subjected to significant bias pressure causing plastic deformation
Solution Approach 1:
The insulator is designed with a movable structure that allows the central terminal to dynamically adjust its position relative to the outer conductor. The movable insulator enables the central terminal to offset and absorb radial deviations through controlled movement, reducing the bias pressure on the elastic cantilever while maintaining reliable electrical contact.
2Adaptability or versatility
If a larger inner cavity is formed in the insulator to allow central terminal offset, then the central terminal can be offset in the insulator, but the volume of the insulator and entire connector increases
Solution Approach 1:
The insulator employs a movable structure that enables the central terminal to offset within a compact space. Instead of providing a large static inner cavity, the movable design allows the central terminal to achieve the necessary offset range through controlled movement, significantly reducing the overall connector volume while maintaining adaptability.
Solution Approach 2:
The movable insulator structure allows the central terminal to be nested within the insulator in a space-efficient manner. The compact nested design enables offset capability without requiring a large inner cavity, thus minimizing the connector volume.
3Reliability
If the elastic cantilever is designed to absorb radial deviation, then electrical contact is maintained, but the elastic cantilever undergoes plastic deformation under significant bias pressure
Solution Approach 1:
The movable insulator structure dynamically adjusts the position of the central terminal to absorb radial deviations, reducing the burden on the elastic cantilever. This dynamic adjustment mechanism maintains electrical contact reliability while minimizing the bias pressure that would otherwise cause plastic deformation of the elastic cantilever.

AI summary
A connector comprises an outer conductor, an insulator, and a central terminal. The outer conductor includes an upper outer conductor and a lower outer conductor. The insulator is provided in the outer conductor and includes an upper insulator and a lower insulator. The central terminal is arranged in the insulator. The upper insulator and the lower insulator are assembled together in a sliding fit, allowing the upper insulator to move relative to the lower insulator. The upper outer conductor and the lower outer conductor are movably engaged together, allowing the upper outer conductor to move together with the upper insulator.
