Waterproof Connector Snap Ring Mechanism for Humidity Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector devices are prone to separation and reduced transmission efficiency when exposed to water vapor, leading to unreliable electrical connections.
Innovation Solution
A waterproof connector device design featuring a plug connector and socket connector with a snap ring mechanism, where the snap ring's first and second snap arms engage through holes in the retaining portions of the connectors to secure their relative positions, preventing separation and ensuring a watertight seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connector devices are exposed to the ambience for easy access and operation, then ease of operation is improved, but water vapor seeps into the connector causing reduced reliability
Solution Approach 1:
The connector device is divided into separate plug and socket components that can be independently handled and connected only when needed. This segmentation allows the connectors to remain exposed and accessible during storage while preventing water vapor ingress during operation by ensuring they are only connected in controlled environments.
Solution Approach 2:
A waterproof seal structure is implemented at the connection interface between plug and socket, using flexible sealing elements that prevent water vapor from seeping into the connector during operation, thus maintaining reliability while allowing ambient exposure when disconnected.
2Ease of manufacture
If the connector structure is simplified for ease of manufacture, then ease of manufacture is improved, but the ability to securely engage and prevent separation deteriorates
Solution Approach 1:
The connector employs a dynamic engagement mechanism where the plug and socket automatically lock together upon insertion through elastic deformation of engagement arms. This dynamic action ensures secure engagement without complex fastening procedures, maintaining ease of manufacture while preventing separation during use.
3Adaptability or versatility
If the connector allows repeated insertion and removal for versatility, then adaptability is improved, but the engagement becomes insecure and separation occurs
Solution Approach 1:
The engagement mechanism uses elastic deformation that resets with each insertion cycle, allowing repeated connection and disconnection while maintaining secure engagement. The elastic arms flex during insertion to engage the locking structure, then return to their original position, ensuring consistent engagement stability across multiple uses.
Solution Approach 2:
The connector combines multiple functions into a single integrated structure: the engagement arms serve both as guiding elements during insertion and as locking mechanisms to prevent separation. This merging of functions maintains adaptability for repeated use while ensuring reliable engagement without requiring separate components.

AI summary
A waterproof connector device includes a plug connector and a snap ring. The plug connector has a plug main body and a plurality of conductive terminals. The plug main body has a plugging column and a retaining portion extending from the bottom edge of the plugging column. The conductive terminals are disposed in the plug main body, and are inserted in the plugging column and partially exposed from the plugging column. The snap ring has an annular main body, a plurality of first snap arms and a plurality of second snap arms. The directions of extensions of the first snap arms and the second snap arms are substantially opposite. By this configuration, the first snap arms can detachably pass through the retaining portion for fixing the relative position of the snap ring and the plug connector. Additionally, the present disclosure also provides a waterproof connector device assembly.
