Flat Wiring Member Connection Structure for Vehicle Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wiring member connection structures in vehicles have a high number of connection points, which reduces the reliability of electrical connections between mainline and branch wiring members, especially when these connections are made through a power supply distribution box.
Innovation Solution
A wiring member connection structure featuring a flat, belt-like conductor with an insulating coating, where bolts are perpendicularly bonded to the conductor's surface, and a circuit board with connectors is fastened to these bolts, allowing for connections without cutting the mainline wiring member, along with a casing that covers the circuit board to expose the connectors, reducing the number of connection points and improving reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mainline wiring member is cut at a branch portion and terminal piece structures are provided at cut portions to connect through a power supply distribution box, then the branch wiring member can be electrically connected to the mainline wiring member, but the number of connection places increases and reliability of electric connection is lowered
Solution Approach 1:
The invention extracts the connection function from the power supply distribution box and relocates it to an intermediate position on the mainline wiring member itself. By providing a connection portion directly on the mainline wiring member, the system eliminates the need to route connections through the distribution box, thereby reducing the number of connection places and improving reliability while maintaining the ability to connect branch wiring members.
2Adaptability or versatility
If multiple connection places are created to connect mainline and branch wiring members through a distribution box, then wiring flexibility is improved, but the complexity of the connection structure increases
Solution Approach 1:
The invention segments the connection function by providing separate connection portions at intermediate positions on the mainline wiring member, allowing independent connection points without requiring a centralized distribution box. This segmentation enables flexible wiring configurations while simplifying the overall connection structure by eliminating the need for complex internal routing through the distribution box.

AI summary
A wiring member connection structure is provided. The wiring member connection structure includes: a flat wiring member formed by covering an outer circumference of a belt-like flat conductor with an insulating coating; a bolt which is erect and bonded perpendicularly to a conductor flat surface of the flat conductor exposed at an intermediate position of the flat wiring member where the coating is removed; a circuit board that has a connector conductively connected to the bolt through a circuit conductor and that is fastened and fixed to the bolt penetrating the circuit board; and a casing that has a casing bottom wall including a bolt insertion hole through which the bolt is inserted to penetrate the circuit board, and that covers the circuit board so as to expose a connector fitting portion of the connector to the outside.
