Connector Housing Fastening Structure for Wire Vibration Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for suppressing vibration of terminal-equipped electrical wires inside a connector housing require protrusions on the terminal, which can affect the inner surface of the cavity.
Innovation Solution
A connector-equipped electrical wire design featuring a connector housing with multiple cavities and a full fastening mechanism that adjusts the regulatory surfaces of these cavities to minimize vibration without needing protrusions on the terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a protrusion is provided on the terminal to suppress vibration, then vibration suppression is achieved, but the protrusion affects the inner surface of the cavity
Solution Approach 1:
Instead of adding a protrusion to the terminal (active element), the invention inverts the approach by modifying the cavity housing (passive element) to have a movable regulatory surface that actively suppresses vibration. This reverses which component carries the vibration suppression function, eliminating the need for terminal protrusions that would contact and potentially damage the cavity inner surface.
Solution Approach 2:
The regulatory surface of the second cavity is designed to be movable relative to the terminal-equipped wire, transitioning between a first position (when housings are not fully fastened) and a second position (when housings are fully fastened). This dynamic adjustment allows the cavity structure itself to adapt and suppress vibration without requiring static protrusions on the terminal.
2Stability of the object's composition
If the connector housing is fully fastened to suppress vibration, then stability is improved, but the structure becomes more complex
Solution Approach 1:
The invention combines the vibration suppression function with the existing full fastening mechanism that maintains the mounted state of the first and second housings. The regulatory surface's vibration suppression action is integrated into the normal fastening operation, rather than requiring a separate dedicated vibration suppression mechanism, thereby reducing overall device complexity.
Solution Approach 2:
The full fastening portion serves multiple functions: it maintains the mounted state of the first and second housings, and simultaneously causes the regulatory surface to move to the second position for vibration suppression. This multi-functionality eliminates the need for separate vibration suppression components, reducing structural complexity.

AI summary
A connector-equipped electrical wire includes a connector housing in which a cavity is formed and a terminal-equipped electrical wire inserted into the cavity. In a first state before full fastening by a full fastening portion is achieved and in which a first cavity communicates with a second cavity corresponding thereto, a first portion of the terminal-equipped wire is configured to pass through the second cavity and fit into the first cavity, and a second portion of the terminal-equipped wire is fitted into the second cavity. In a second state in which full fastening by the full fastening portion is achieved, when observed in an axial direction of the cavity, a regulatory surface of an inner surface of the second cavity approaches closer to the second portion than when in the first state.
