Spring-Loaded Holding Frame for Modular Plug Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing modular connector systems face issues with tolerance differences among various connector modules, leading to incomplete or excessive contact, which can result in mechanical failures and faulty connections due to design-related tolerance variations.
Innovation Solution
A rectangular holding frame with recesses and spring elements that exert a force in the plug-in direction, allowing connector modules to be moved into an end position, compensating for tolerances and preventing over-plugging by displacing modules against the spring force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If connector modules with different tolerances are used in modular connector systems, then the versatility and adaptability of the system is improved, but the reliability of contact deteriorates due to incomplete or excessive contact
Solution Approach 1:
The patent introduces spring elements that apply a compensating force to adjust the contact parameters dynamically. The spring force compensates for tolerance variations in plug-in depth among different connector modules, ensuring reliable contact despite differences in module dimensions and tolerances.
Solution Approach 2:
The holding frame transitions from a static rigid structure to a dynamic system with spring elements that can adapt to varying plug-in depths. The spring elements dynamically adjust the contact force based on the actual position of each connector module, accommodating tolerance differences while maintaining reliable contact.
2Manufacturing precision
If rigid holding frames with fixed recesses are used, then the manufacturing precision and structural stability are improved, but the ability to compensate for tolerance differences deteriorates
Solution Approach 1:
The holding frame incorporates spring elements that transform the rigid fixed structure into a dynamic system capable of adapting to tolerance variations. The springs maintain the structural precision of the holding frame while adding the flexibility needed to compensate for connector module tolerance differences.
Solution Approach 2:
The spring elements act as pre-installed cushioning elements that anticipate and compensate for potential tolerance issues before they cause contact problems. The springs are pre-loaded to provide the necessary compensating force, ensuring reliable contact even when plug-in depths vary within tolerance ranges.
3Ease of operation
If connector modules are allowed to vary in plug-in depth, then the ease of assembly and operation are improved, but the harmful effects of over-plugging and loose contact increase
Solution Approach 1:
The spring elements serve as protective cushioning that prevents both over-plugging and loose contact. By providing a compliant contact interface, the springs absorb excessive force when modules are inserted too deeply while maintaining adequate contact force when modules are inserted shallower than ideal, thus preventing contact defects despite variations in assembly precision.
Solution Approach 2:
The patent converts the potentially harmful effect of tolerance variations and plug-in depth differences into a beneficial feature. The spring elements utilize the force from improper insertion (too deep or too shallow) to maintain optimal contact pressure, transforming assembly variations from a source of contact defects into a mechanism that self-adjusts to ensure reliable contact.
