Contact Spring Holding Jig with Position Restricting Walls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing contact spring holding jigs for grease application complicate the attachment and detachment of connector terminal contact springs and interfere with the target region of grease application, requiring complex structures to prevent interference.
Innovation Solution
A contact spring holding jig with a spring placement portion and spring position restricting walls that allow easy attachment and detachment of connector terminal contact springs without interfering with the grease application area, using inner and outer walls to restrict the position of the connecting portion and prevent movement during grease application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If parts other than spring piece and surrounding target region are fixed to the jig, then the contact spring can be held securely, but the attachment and detachment work becomes complicated
Solution Approach 1:
The invention extracts only the essential function needed for holding the contact spring - using a simple wall structure that restricts position without requiring complex fixing mechanisms. The wall portion is positioned to restrict the contact spring's movement while leaving other parts free, thereby simplifying attachment and detachment operations while maintaining holding stability.
2Reliability
If the jig structure is made complex to hold the contact spring without interfering with grease application, then the contact spring can be held securely, but the jig structure becomes complicated
Solution Approach 1:
The invention extracts the essential holding function and implements it through a simple wall structure rather than a complex mechanism. The wall portion is strategically positioned to restrict the contact spring's position without interfering with the grease application target region, achieving reliable holding with minimal structural complexity.
Solution Approach 2:
The invention applies local quality by creating a wall portion at a specific location that restricts the contact spring's position only where necessary. The wall is positioned to prevent interference with the grease application target region while still providing adequate holding, thereby achieving local optimization of the structure.
3Device complexity
If a simple wall structure is used to restrict contact spring position, then the jig structure remains simple, but the holding performance may be insufficient
Solution Approach 1:
The invention enhances the simple wall structure by optimizing its position and dimensions locally. The wall portion is positioned to restrict the contact spring's position effectively while maintaining simplicity. The wall's height and position are specifically designed to prevent the contact spring from moving into the grease application target region, providing sufficient holding performance without increasing overall structural complexity.

AI summary
A contact spring holding jig for grease application includes a spring placement portion on which a connector terminal contact spring is to be placed, and a spring position restricting wall. The connector terminal contact spring includes a plurality of spring pieces and a connecting portion positioning at an end portion of the connector terminal contact spring. The plurality of spring pieces include a gap with adjacent spring pieces are connected to be arranged side by side by the connecting portion. The connector terminal contact spring is placed with the connecting portion facing downward, on the spring placement portion.
