Battery Wiring Module Protector for Extra Wire Length Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiring modules in power storage modules for electric and hybrid automobiles do not adequately prevent the extra length portions of electric wires from contacting external components during assembly or connection, leading to potential breakage of connection points due to external forces.
Innovation Solution
A wiring module with a protector that includes an extra length portion housing portion and a holder portion to manage the extra length of electric wires, allowing them to be moved outside the protector while being held, reducing contact with external components and minimizing movement due to vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the extra length portion of electric wires is made longer to ensure proper connection and movement capability, then the ease of operation and adaptability improve, but the risk of contact with external components increases leading to connection breakage
Solution Approach 1:
A guide member is introduced as an intermediary component between the extra length portion of the electric wire and the external environment. The guide member has a guide hole through which the electric wire passes, constraining the wire's movement path and preventing contact with external components while maintaining the wire's flexibility and connection capability.
Solution Approach 2:
The guide member acts as a protective structure that provides a defined pathway for the electric wire. This structure protects the wire from external forces and contact with other components while allowing the wire to move flexibly within the constrained path during assembly and operation.
2Adaptability or versatility
If the extra length portion is allowed to move freely outside the protector, then the adaptability and ease of assembly improve, but harmful contact with external components occurs causing connection breakage
Solution Approach 1:
The guide member serves as a mediator that enables the electric wire to move freely during assembly while preventing harmful contact with external components. The guide hole provides a controlled pathway that maintains assembly flexibility but eliminates exposure to external forces and potential damage sources.
3Ease of operation
If the connector is not connected to a target connector, then the ease of operation and adaptability improve, but the extra length portion may contact external components and receive forces that break the connection
Solution Approach 1:
The guide member provides continuous protection for the electric wire regardless of the connector's connection state. When the connector is disconnected, the guide member still constrains the extra length portion of the wire, preventing it from contacting external components or receiving forces that could break the connection during assembly or disconnection operations.

AI summary
A wiring module is to be coupled to a power storage component group including power storage components that are arranged. The wiring module includes a connector, electric wires extending from the connector, and a protector having insulating properties and to be attached to the power storage component group. The electric wires include an extra length portion. The extra length portion includes an extending end portion that is disposed close to the connector, a basal portion that is positioned on the protector, and a body portion that is between the extending end portion and the basal portion. The protector includes an extra length portion housing portion in which the body portion is arranged so as to be moved out therefrom and a holder portion that detachably holds the extending end portion or the connector.
