Terminal Holding Structure With Screw Guide Pin Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing terminal holding structures in vehicle battery wiring modules face inefficiencies and reliability issues due to inclined fastening of terminals, which reduces task efficiency and connection reliability.
Innovation Solution
A terminal holding structure with a guide member that aligns the screw's advancement direction, preventing inclined fastening by guiding the screw with a metallic guide pin, ensuring proper alignment and secure fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the screw is fastened without a guide member, then the fastening operation is simple, but inclined fastening occurs reducing connection reliability
Solution Approach 1:
A guide member is introduced as an intermediary component between the screw and the terminal. The guide member includes a guide hole that receives the screw and constrains its movement, ensuring the screw advances in the correct direction. This mediator prevents inclined fastening and improves connection reliability without significantly complicating the overall structure.
2Productivity
If the screw is fastened without alignment guidance, then the operation is quick, but task efficiency decreases due to specialty work requirements
Solution Approach 1:
The guide member serves as a mediator that automatically aligns the screw with the terminal, eliminating the need for operators to perform precise manual alignment. The guide hole in the guide member physically directs the screw, making the fastening operation easier and improving task efficiency by reducing specialty work requirements.
3Stability of the object's composition
If the screw advances freely without guidance, then the fastening process is simple, but wobbling of the terminal occurs
Solution Approach 1:
The guide member acts as a stabilizing intermediary that prevents the screw from advancing at an incline. The guide hole constrains the screw's path, ensuring it moves straight and preventing terminal wobbling. This maintains terminal stability while adding only a single guide member to the structure.
4Reliability
If a guide member is added to the case, then inclined fastening is prevented, but the device complexity increases
Solution Approach 1:
The guide member is designed as a simple intermediary component with a guide hole that fits into the case. It provides the necessary guidance function to prevent inclined fastening and improve connection reliability, while its straightforward design minimizes the increase in overall device complexity.

AI summary
A screw insertion hole 24 into which a cylindrical shaft portion 17 of a screw 16 is to be inserted is formed in a terminal accommodation portion 22. Also, a guide pin 25 made of metal is provided through insert molding so as to correspond with the screw insertion hole 24. The guide pin 25 is for matching a direction in which the screw 16 advances with a prescribed direction, that is, a vertical direction orthogonal to a fastening surface 23.
