Wiring Module Connector Movement Restriction Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiring modules face challenges in space efficiency and protection of detection wires from external forces, especially when a pigtail connector is not feasible, leading to potential movement and risk of force transmission to the detection wires.
Innovation Solution
A wiring module with an insulating protector that houses interconnection conductors and detection wires, featuring a connector with a movement restricting mechanism, including a support base portion, rear stopping portion, lateral stopping portions, upper stopping portions, and cantilevered elastic pieces, to absorb and restrict external forces, ensuring the connector remains stable and prevents force transmission to the detection wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pigtail connector is employed to cancel external force, then the connector is protected from external force transmission, but the wiring module requires sufficient external space which is not always available
Solution Approach 1:
The harmful function of the pigtail connector (external force cancellation through flexure) is extracted and replaced by a dedicated movement restricting means integrated into the insulating protector. The support base portion with stopping portions provides direct mechanical constraint to the connector, eliminating the need for the pigtail's flexible force-cancellation mechanism and the associated space requirement.
Solution Approach 2:
The insulating protector serves as an intermediary structure that directly restricts connector movement through integrated stopping portions. This intermediary mechanism provides the movement restriction function without requiring the external space needed by the pigtail connector approach, thereby resolving the contradiction between reliability and space requirement.
2Area of stationary object
If a female connector is provided at the leading ends of detection wires without a pigtail, then space efficiency is improved, but external force acting on the connector during mating is not cancelled, resulting in connector movement and risk of force transmission to detection wires
Solution Approach 1:
The movement restricting means is merged with the insulating protector structure through integration of the support base portion and stopping portions. This combined structure provides both insulation and connector movement restriction functions within the same component, achieving space efficiency while protecting detection wires from external force transmission.
Solution Approach 2:
The stopping portions are designed to preliminarily restrict connector movement in potential harmful directions before external force can be transmitted to the detection wires. By providing pre-positioned mechanical constraints, the system prevents harmful movements rather than reacting to them after occurrence.

AI summary
A wiring module is for attachment to a power module in which power elements that store or generate electrical power are arranged side-by-side. The wiring module includes: an insulating protector that houses interconnection conductors for interconnecting the power elements; detection wires that are housed in the insulating protector, extend from a side corresponding to the power elements, and detect a state of the power elements; a connector that is provided at an end portion of the detection wires and is arranged inside the insulating protector; and a movement restricting means that is provided in the insulating protector and is for restricting movement of the connector by locking the connector.
