Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional high-frequency connectors for communication devices under vibrational conditions suffer from external interference, oxidation, rust, and limited shock-absorbing and damp-proofing due to gaps caused by slits, leading to efficiency loss and increased high-frequency output loss.
Innovation Solution
A high-frequency connector assembly design featuring a conductive pin with a slit at the periphery for an O-ring insertion, an expanded section with an annular groove for stable positioning, and a nut for external force resistance, along with adapters for component connection, ensuring sealed and stable signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a slit is arranged at the outer periphery of the terminal block to provide resilient pressing force, then the connector can achieve easy assembly and shock-absorbing effect, but external air permeates through the slit causing oxidation and rustiness of components
Solution Approach 1:
An O-ring is introduced as an intermediary sealing element between the terminal block and the matching terminal block. The O-ring fits into a groove at the receiving periphery and effectively blocks the slit opening, preventing air permeation and oxidation while preserving the resilient pressing force provided by the slit.
2Device complexity
If a slit is arranged at the outer periphery of the terminal block, then the connector structure is simplified and assembly is easier, but high-frequency output loss increases due to the opened border
Solution Approach 1:
The O-ring acts as a sealing intermediary that closes the border opening created by the slit. This maintains the simplicity of the connector structure while preventing high-frequency signal leakage that would occur through the open slit, thereby reducing high-frequency output loss.
3Reliability
If Beryllium-Copper Alloy is used to enhance transmission efficiency and shock-absorbing effect, then the connector performance is improved, but the cost increases and environmental friendliness decreases
Solution Approach 1:
The patent replaces expensive Beryllium-Copper Alloy with ordinary metal materials combined with a simple O-ring sealing structure. This substitution achieves comparable or superior performance in transmission efficiency and shock-absorbing capability while dramatically reducing manufacturing cost and improving environmental compatibility.
4Force
If the slit provides resilient pressing force bias, then the connector achieves shock-absorbing effect, but the buffering and shock-absorbing effects against external vibration are limited
Solution Approach 1:
The O-ring, being a flexible elastic component, is introduced to enhance the shock-absorbing capability. When external vibration or impact occurs, the O-ring can deform elastically to absorb shock energy, providing superior buffering and shock-absorbing effects compared to the rigid resilient pressing force of the slit alone.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides enhanced transmission efficiency, damp-proofing, and shock-absorbing capabilities without using Beryllium-Copper Alloy, maintaining signal stability under vibrational conditions and resisting external interference.
Implementation Method 1
an O-ring to be inlaid in a connecting section of the second connector... an O-ring sealing effect is provided to ensure high-frequency transmission efficiency
Implementation Method 2
the contracted edge having a slope at the end of the receiving periphery pressingly abuts against the annular groove... providing desired shock-absorbing and damp-proof effects

AI summary
A high-frequency connector assembly includes a first connector having a conductive pin and formed with at least one slit at a receiving periphery thereof for allowing a second connector inlaid with an O-ring to be inserted therein. The pin in the first connecter can be received by a pin holder in the second connector. An expanded section at a rear portion of the second connector is received by an expanded section of the first connector. An annular groove formed adjacent to the expanded section on the second connector pressingly abuts against a contracted edge slope at an end of the receiving periphery of the first connector. The connector assembly facilitates mitigating attrition caused by frequent vibration and provides a damp-proof effect, thereby ensuring a desired transmission efficiency.
