Electronic Component Assembly Structure for Junction Box Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing assembly structures of electronic components, such as relay modules, suffer from poor workability due to instability and inclination issues when assembling multiple components, particularly in electrical junction boxes, as the spring portions fitted to relay terminals can cause the components to incline, making the assembly process inefficient.
Innovation Solution
The proposed assembly structure includes a housing member with a first chamber to guide the electronic component's main body and a second chamber to accommodate terminal fittings, where the terminal fitting's fitting portion is positioned to contact the terminal when at least one-third of the component's height is accommodated, stabilizing the posture and improving assembly efficiency. This is achieved by adjusting the height positions of the fitting portions and terminal fittings, and using inclined portions to guide the fitting portions into appropriate insertion directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the spring portion is fitted to the relay terminal and the relay is held by the holding member, then the relay can be assembled to the holding member, but the relay easily inclines and the posture is not stabilized, degrading workability
Solution Approach 1:
The patent applies preliminary action by providing guide portions on the holding member that guide the relay terminals before they are fitted into the spring portions. This preliminary guidance stabilizes the relay posture during the assembly process, preventing inclination and improving workability when assembling multiple relays.
2Ease of manufacture
If multiple relays are assembled individually with each terminal fitted to spring portion, then the relays can be assembled to the holding member, but the workability is further degraded when the number of relays increases
Solution Approach 1:
The guide portions are pre-formed on the holding member to automatically guide multiple relay terminals into correct positions simultaneously. This preliminary guidance structure enables batch assembly of multiple relays without requiring individual fitting operations, significantly improving assembly efficiency and reducing time loss.
