Connector Mounting Member Vibration Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors fail to effectively suppress the transmission of wire vibration to the housing, as the housing and spacer or seal member are not designed to absorb or dissipate the vibration, leading to resonance and potential damage.
Innovation Solution
A connector design featuring a terminal fitting, a housing with a seal member and a mounting member that sandwiches the seal member, allowing the mounting member to absorb and dissipate vibration forces, reducing the transmission of vibrations to the housing through its movable nature and specific structural features like deflectable engaging portions and a housing restricting surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the housing and spacer are locked to prevent relative displacement, then the structural stability is improved, but the wire vibration is transmitted to the housing without attenuation
Solution Approach 1:
The mounting member is designed to be movable relative to the housing, allowing it to dynamically absorb and attenuate wire vibrations through relative motion, while the housing-spacer locking structure maintains overall structural stability. This dynamic design enables the system to adapt to vibration forces without compromising structural integrity.
Solution Approach 2:
The mounting member acts as an intermediary element between the wire/seal member assembly and the housing. It absorbs and dissipates vibration energy through its movable connection, preventing direct transmission of vibrations to the housing while maintaining the structural connection.
2Stability of the object's composition
If the housing and receptacle are locked to prevent relative displacement, then the structural stability is improved, but the wire vibration is transmitted to the housing without attenuation
Solution Approach 1:
The mounting member provides a dynamic, movable connection between the seal member and housing, enabling vibration absorption through relative motion. This dynamic element decouples the vibration transmission path while the locked housing-receptacle connection maintains structural stability.
Solution Approach 2:
The mounting member serves as a mediator that intercepts and dissipates vibration energy before it can reach the housing. Its movable design allows it to absorb vibration forces, protecting the housing from vibration damage while maintaining structural integrity.
3Object-affected harmful factors
If the mounting member is made movable to suppress vibration transmission, then the vibration attenuation is improved, but the structural stability may be compromised
Solution Approach 1:
The mounting member is designed with controlled movability that allows vibration absorption while maintaining structural stability. The movable connection is constrained to specific degrees of freedom that enable vibration damping without compromising the overall structural integrity of the connector assembly.
Solution Approach 2:
The connector is divided into functionally independent segments: the housing-spacer assembly provides structural stability through locked connections, while the mounting member provides vibration attenuation through movable connections. This segmentation allows each component to optimize its specific function without compromising the other.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The connector effectively suppresses wire vibration transmission to the housing by utilizing a movable mounting member and structural features that absorb and dissipate vibration, enhancing the connector's durability and reliability.
Implementation Method 1
the vibration of a wire is transmitted to the housing without being attenuated via the spacer and the outer housing holding the seal member
Implementation Method 2
the mounting member being in contact with the seal member and movably mounted on the housing... suppress the vibration of a wire to be transmitted to a housing

AI summary
A connector 10 includes a terminal fitting 11, a housing 12, a seal member 13 and a mounting member 14. The terminal fitting 11 is connected to a wire 80. The seal member 13 includes a seal hole 52 through which the wire 80 is passed in a liquid-tight manner. The mounting member 14 holds the seal member 13 by sandwiching the seal member 13 between the housing 12 and the mounting member 14. The mounting member 14 is in contact with the seal member 13 and movably mounted on the housing 12.
