Electrical Junction Box Latching Part for Wire Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operation of connecting electronic control units to connectors in traditional electrical junction boxes is cumbersome and labor-intensive due to the need to manually manage and insert electric wires and connectors into the unit storing room, making it difficult to securely connect components without causing the electronic control unit to shift and complicating the process.
Innovation Solution
The introduction of a latching part on the electrical junction box, which catches electric wires and connectors at the entrance of the unit storing room, allowing them to be easily held and managed by hand, reducing the workload and improving the design flexibility for the latching part's placement, while preventing accidental disconnection during transportation or operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If electric wires and connectors are arranged in advance in the unit storing room, then the electrical junction box can be compactly packed and installed in the vehicle, but the operation of connecting connectors to electronic control units becomes extremely troublesome and labor-intensive
Solution Approach 1:
The electrical junction box is divided into a first storing room for electric wires and a second storing room for electronic control units. This segmentation allows wires to be organized in one dedicated space while control units are accessed separately, making the connection operation less cumbersome while maintaining compact overall structure.
Solution Approach 2:
A guide member is introduced as an intermediary component that extends from the first storing room to the opening. This guide member facilitates the extraction and connection of electric wires by providing a structured path, reducing the difficulty of the connection operation while preserving the pre-arranged compact layout.
2Ease of operation
If connectors are held by hand during connection operation, then connection can be performed, but the hand supporting the electronic control unit shakes making it difficult to connect smoothly
Solution Approach 1:
By separating the storing rooms for wires and control units, the connector extraction point is positioned away from the control unit storage area. This allows one hand to stabilize the control unit in the second storing room while the other hand easily accesses connectors through the guide member in the first storing room, reducing shaking and improving connection stability.
Solution Approach 2:
The guide member acts as a mediator that extends the reach of the operator's hand from the wire storing room to the opening. This intermediary structure provides a stable reference point and extended leverage, making it easier to hold and manipulate connectors without causing the control unit to shake during connection.
3Ease of operation
If force is applied to draw electric wires and connectors back into the unit storing room, then connectors can be connected to terminals, but the workload of the operator becomes heavier
Solution Approach 1:
The separation of storing rooms allows connectors to be naturally positioned in the first storing room away from the control unit area. This spatial segmentation eliminates the need to forcefully draw wires across the entire box, reducing the operator's workload and improving connection efficiency.
Solution Approach 2:
The guide member serves as an intermediary that extends from the first storing room to the opening, providing a mechanical advantage for extracting wires. This intermediary structure reduces the force required to pull wires and connectors, making the connection operation less labor-intensive and improving overall productivity.

AI summary
A storing box is formed with a unit storing room storing an electronic control unit. The storing box is formed with a latching part by which an electric wire or a connector connected to one end of the electric wire is caught. The electric wire passes through an inner side of the unit storing room and is drawn out from a storing opening which is an entrance for storing the electronic control unit.
