RF Connector Torque Ring with Pre-Set Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RF connectors lack a reliable method to apply consistent pre-set torque to mated pairs, leading to inconsistent pressure and repeatability issues during testing and calibration, especially with commercially available torque wrenches that slip or cannot be used with spin rings.
Innovation Solution
A torque ring or nut system is introduced, featuring an inner and outer ring structure with calibrated pre-set torque values, allowing for secure and repeatable torque application to RF and microwave coaxial connectors using finger pressure or mechanical devices, with options for removable or integrated designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spin ring is used to tighten the connector, then the connector can be easily tightened, but the torque applied is inconsistent and cannot be pre-set
Solution Approach 1:
The torque ring incorporates a pre-set torque mechanism that automatically applies the correct torque value when the ring is rotated. The friction elements and spring mechanism are pre-configured to engage at the precise torque threshold, eliminating the need for operator judgment and ensuring consistent torque application across all connections.
Solution Approach 2:
The invention introduces friction elements and a spring mechanism as intermediaries between the user's rotational input and the connector tightening action. These intermediaries control the torque transmission, allowing pre-set torque values to be applied automatically while maintaining ease of operation through simple ring rotation.
2Manufacturing precision
If a commercially available torque wrench is used, then pre-set torque can be applied, but the wrench slips or dis-engages and cannot be used with spin rings
Solution Approach 1:
The invention merges the torque application function directly into the spin ring structure itself, combining what were previously separate functions (spin ring for tightening and torque wrench for precision) into a single integrated component. This eliminates the incompatibility between spin rings and torque wrenches while maintaining both ease of operation and pre-set torque capability.
Solution Approach 2:
The torque ring is designed to be self-regulating, with the pre-set torque mechanism automatically engaging and disengaging the friction elements at the correct torque threshold. The system serves itself by automatically controlling torque application without requiring external monitoring or adjustment, preventing both under-tightening and over-tightening.
3Reliability
If the spin ring is left on the connector during testing, then the connector remains protected, but it prevents the use of a torque wrench to achieve torque specification
Solution Approach 1:
The torque ring serves multiple functions: it provides connector protection during handling and testing, applies pre-set torque automatically, and can be easily removed or left in place based on testing requirements. The design allows the same component to fulfill both protective and torque-application roles, eliminating the need to choose between different devices.
4Strength
If hex coupling nuts are permanently fastened to connectors, then the connectors are secure, but there are no provisions to apply correct torque to the coupled pair
Solution Approach 1:
The invention applies torque control locally at the hex coupling nut interface where it is most needed. The friction elements and spring mechanism are positioned to engage directly with the nut's hex features, providing precise torque control at the critical connection point without affecting the overall connector security or requiring changes to the permanent fastening design.
