Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing probes for inspecting multipolar connectors face accuracy issues due to positional displacement between terminals and central conductors, leading to decreased inspection accuracy.
Innovation Solution
A probe configuration featuring a flange, coaxial cable, plunger, and spring, where the spring elastically deforms to align the terminal and probe pin positions accurately, with the coaxial cable having lower flexural rigidity than the spring to facilitate precise alignment and prevent excessive deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple central conductors are brought into contact with multiple terminals simultaneously, then inspection efficiency is improved, but inspection accuracy deteriorates due to positional displacement
Solution Approach 1:
The probe employs a dynamic alignment mechanism where the plunger can move axially to adjust the position of probe pins. This dynamic adjustment allows the system to maintain optimal contact alignment between probe pins and terminals during inspection, resolving the positional displacement issue that occurs with static multi-conductor configurations.
Solution Approach 2:
The invention replaces the traditional mechanical alignment system with an optical alignment system. The optical alignment mechanism uses light-based reference marks and detection systems to precisely position the plunger and probe pins, eliminating the mechanical positioning errors that cause inspection accuracy deterioration in multi-conductor simultaneous contact configurations.
2Ease of operation
If the coaxial cable has high flexibility, then ease of operation is improved, but positional stability deteriorates causing alignment errors
Solution Approach 1:
The invention introduces a support structure as an intermediary between the coaxial cable and the probe pin mounting point. This support structure provides mechanical stability and positional reference, preventing the flexible cable from causing alignment errors while maintaining the cable's flexibility for ease of operation and routing.
Solution Approach 2:
The invention changes the physical parameters of the cable assembly by introducing rigid support elements and structured routing channels. These parameter changes maintain the electrical and operational flexibility of the coaxial cable while providing the positional stability needed for accurate inspection, effectively decoupling flexibility from positional instability.
