Connector With Elastically Deformable Joint For Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors lack sufficient vibration resistance, especially when connecting objects with different vibration patterns, as the elastic joint pieces may not adequately absorb independent vibrations.
Innovation Solution
A connector design featuring a terminal portion with a male contact on one side and a female contact on the other, incorporating an elastically deformable joint portion that extends longer than traditional configurations, allowing for enhanced vibration absorption and resistance, and a U-shaped joint configuration to accommodate limited spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If female contacts are formed at both end portions of the terminal portion, then electrical connection is achieved, but the joint portion length is insufficient to absorb vibrations
Solution Approach 1:
The patent applies asymmetry by forming a male contact at one end portion of the terminal portion and a female contact at the other end portion, rather than using identical female contacts at both ends. This asymmetric configuration enables the joint portion to extend longer toward the male contact side, providing sufficient length to absorb vibrations while maintaining electrical connection functionality.
2Reliability
If the joint portion is lengthened to absorb vibrations, then vibration resistance improves, but the connector size increases
Solution Approach 1:
The patent applies local quality by concentrating the vibration absorption function in the joint portion through its extended length, while keeping the overall connector structure compact. The male contact side allows the joint portion to extend, providing localized vibration absorption capability without proportionally increasing the entire connector volume.
Solution Approach 2:
The patent applies dynamics by making the joint portion elastically deformable, allowing it to dynamically absorb vibrations through elastic deformation. This dynamic vibration absorption mechanism enables the joint portion to be long enough to absorb vibrations while maintaining a compact connector structure that only increases in volume when vibrations occur.
3Reliability
If the joint portion is made longer to absorb independent vibrations of two objects, then vibration resistance improves, but the connector becomes more complex
Solution Approach 1:
The patent applies merging by integrating the joint portion as a single elastically deformable component that combines both mechanical connection and vibration absorption functions. The male and female contacts are also integrated into the terminal portion structure, creating a unified design that achieves vibration resistance without requiring separate complex vibration absorption mechanisms.
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 design provides improved vibration resistance by lengthening the joint portion, allowing it to effectively absorb vibrations and reduce abrasion, while maintaining a compact form factor and suppressing looseness between connector and housing components.
Implementation Method 1
an elastically deformable joint portion that joins the connector-side male contact and the connector-side female contact to each other

AI summary
Provided is a connector having excellent vibration resistance. The invention applies to a connector including a terminal portion and a connector housing in which the terminal portion is accommodated and electrically connecting a first object to be connected and a second object to be connected via the terminal portion. A main body-side male contact is connected to the first object to be connected. A main body-side female contact is connected to the second object to be connected. The terminal portion has a connector-side male contact that is inserted into the main body-side female contact, a connector-side female contact into which the main body-side male contact is inserted, and an elastically deformable joint portion that joins the connector-side male contact and the connector-side female contact to each other.
