Locking Spring Plug Connector for Vibration-Resistant Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug connector systems face challenges in securely connecting and maintaining contact between conductors while preventing accidental touch and ensuring vibration resistance, often requiring additional components like plastic housings that can be prone to material fatigue.
Innovation Solution
The use of a locking spring that exerts force on a pressure chamfer of the mating connector, establishing a secure connection and additional electrical contact points, eliminating the need for a plastic housing and reducing material fatigue risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a plastic housing is used to connect plug connector and mating connector, then the connection structure is simplified, but material fatigue occurs leading to reduced reliability
Solution Approach 1:
The patent extracts and removes the plastic housing from the connector system, replacing it with a metal locking spring mechanism. The locking spring (140) is mounted on the holding pin (130) and engages with the pressure chamfer (240) to provide the necessary locking force, eliminating the plastic housing entirely and its associated fatigue problems.
Solution Approach 2:
The patent replaces the mechanical plastic housing structure with a metal-based elastic locking mechanism. The locking spring (140) uses elastic deformation to engage with the pressure chamfer (240), substituting the plastic housing's mechanical interlocking function with a more durable elastic-mechanical system.
2Object-affected harmful factors
If additional components are added to ensure vibration resistance and prevent accidental touch, then safety is improved, but device complexity increases
Solution Approach 1:
The locking spring (140) serves multiple functions simultaneously: it provides vibration resistance through its elastic engagement with the pressure chamfer (240), prevents accidental disconnection through the locking mechanism, and the metal construction provides electrical insulation when combined with insulating materials. The holding pin (130) structure with integrated locking spring eliminates the need for separate vibration resistance components and insulation housings.
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
This solution provides a reliable, vibration-resistant electrical connection between the plug and mating connectors, enhancing contact security and reducing the risk of material fatigue, while preventing accidental touch through the use of insulating materials and a resilient locking mechanism.
Implementation Method 1
The locking spring (140) is elastically deformable and is arranged on a lateral surface (131) of the holding pin (130)
Implementation Method 2
The locking spring (140) exerts a force on a pressure chamfer (240) of the mating connector (200) acting in the connecting direction (300) when the plug connector (100) is fully plugged together with the mating connector (200)
