Vehicle Electrical Connection Box Gripping Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electrical connection boxes for vehicles pose a risk of increased man-hours during assembly due to the need for careful handling to avoid touching exposed terminals and components, leading to potential deformation or contamination.
Innovation Solution
An electrical connection box design featuring a holding member with a gripping portion that includes a finger placement area, allowing workers to easily grip the fuse terminals without direct contact, thereby preventing contamination and deformation during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If workers handle the substrate and fuse module directly during assembly, then assembly work can be performed, but there is a risk of touching terminals and electrical components which may cause deformation or contamination, increasing man-hours
Solution Approach 1:
The patent introduces a case member with a holding portion that acts as an intermediary between the worker's hand and the electrical components. The holding portion has a curved surface designed to fit the palm, allowing workers to grip and manipulate the substrate and fuse module without directly touching the terminals or electrical components, thus preventing contamination while maintaining ease of handling
Solution Approach 2:
The case member is designed in advance with an integrated holding portion that provides a safe gripping area before the assembly process begins. This preliminary design feature ensures that workers have a predetermined safe zone to grip the components, eliminating the need for careful avoidance of terminals during handling
2Reliability
If workers are cautious to avoid touching terminals during assembly, then component safety is maintained, but the number of man-hours for work increases
Solution Approach 1:
The holding portion serves as a mediator that separates the worker's hand from the electrical components. By providing a dedicated gripping area on the case member, it allows workers to handle the assembly quickly and confidently without needing to exercise caution, thus maintaining component safety while improving assembly efficiency
Solution Approach 2:
The case member's holding portion is designed to be self-explanatory and self-serving, with its curved surface naturally guiding the worker's hand to the correct gripping position. This eliminates the need for additional training or cautious behavior, allowing workers to efficiently assemble components while ensuring their safety

AI summary
Provided is an electrical connection box according to which it is possible to easily handle a substrate and a fuse module. An electrical connection box for a vehicle includes: an insertion housing into which a plurality of fuses are to be inserted; a plurality of fuse terminals each having one end portion inserted into a surface of the insertion housing, the fuse terminals connecting the fuses to a substrate; and a holding member that is arranged opposing the one surface of the insertion housing and holds the fuse terminals. The holding member includes a gripping portion provided on a side opposite to the insertion housing, and the gripping portion has a finger placement portion used for gripping.
