Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional RF connectors experience weakened or disconnected contacts over time due to reduced pressure, dust accumulation, and vibrations, leading to inefficient signal transmission and communication.
Innovation Solution
A spring-loaded RF connector with a resiliently telescopically formed rod and sleeve member within a housing, ensuring reliable contact with the socket's grounding loop and signal terminal, utilizing inner and outer springs for stable connection and noise elimination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional RF connector uses fixed rigid terminals, then the structure is simple and easy to manufacture, but the contact pressure weakens over time due to vibrations and movements, leading to loose connections and poor signal transmission
Solution Approach 1:
The patent applies the dynamics principle by replacing fixed rigid terminals with spring-loaded terminals that can dynamically adjust their position. The spring mechanism allows the terminal to move and maintain constant contact pressure with the socket, compensating for vibrations and movements during use. This dynamic adjustment ensures reliable signal transmission while managing the complexity through a well-defined mechanical mechanism.
2Reliability
If the RF connector uses spring-loaded terminals for stable contact, then connection reliability improves, but the device complexity increases due to additional spring components and telescopic structures
Solution Approach 1:
The patent applies the nested doll principle by placing the rod member inside the sleeve member, with the spring mechanism nested within the telescopic structure. The rod member can move axially within the sleeve, and the spring is positioned between them, creating a compact nested arrangement. This nesting reduces the overall space required while maintaining the spring-loaded functionality for stable signal transmission.
3Reliability
If conventional RF connectors are used without vibration damping, then the structure remains simple, but vibrations and movements cause terminal misalignment and connection loosening
Solution Approach 1:
The patent applies the beforehand cushioning principle by incorporating a spring mechanism that proactively compensates for vibrations and movements before they cause connection issues. The spring acts as a cushion that absorbs shock and maintains constant contact pressure, preventing terminal misalignment and connection loosening before they occur. This prior cushioning ensures reliable signal transmission in vibrating environments.

AI summary
A RF pass-through connector comprises at least a spring-loaded terminal comprised of a rod member and a sleeve member resiliently telescopically formed in a housing and adapted to be correspondingly contacted with a signal terminal formed in a socket and a receptacle cavity in the socket to be electrically connected with a grounding loop formed in a circuit board fixed in an electronic device, whereby upon a connection of the RF pass-through connector with the socket of the electronic device, a reliable, stable and efficient signal communication or transmission may be obtained through the terminals.
