Exchangeable Terminal Plate Waterproof Sealing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional waterproof and dustproof electronic devices rely on the constant connection of an antenna cable to maintain their sealed state, limiting their usability in scenarios where the external connector is only needed intermittently, such as with personal computers.
Innovation Solution
An electronic device design featuring a casing with a terminal plate that is exchangeably mounted on a flange within the casing, surrounded by a water sealing component, ensuring the terminal plate's outer surface is flush with the casing, thereby preventing water and dust ingress regardless of the terminal plate's position, and allowing for expandability and reliable sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an intermediate connector is disposed in the casing to be waterproof, then waterproof capability is improved, but the device cannot be used when the connector is not connected
Solution Approach 1:
The terminal structure is divided into two independent parts: a fixed waterproof intermediate connector disposed in the casing, and a detachable external connector that can be mounted or removed as needed. The waterproof seal is segmented to work effectively with both connected and disconnected states, allowing the device to maintain waterproof capability while providing flexibility in connector usage.
Solution Approach 2:
The intermediate connector and its waterproof sealing structure are pre-installed and configured in the casing before the external connector is attached. The sealing component is preliminarily positioned to ensure that when the external connector is mounted, the waterproof seal is automatically engaged without requiring additional assembly steps, thus maintaining both waterproof reliability and operational flexibility.
2Reliability
If a fixed connector structure is used to ensure waterproofing, then waterproof capability is improved, but expandability is reduced
Solution Approach 1:
The intermediate connector is designed with universal compatibility to accommodate multiple types of external connectors (such as N-type, F-type, or other standard connectors). The sealing structure is configured to work with various connector forms while maintaining the same waterproof performance, thus providing expandability without compromising waterproof capability.
Solution Approach 2:
The intermediate connector acts as an intermediary component between the internal circuitry and various external connectors. It provides a standardized interface with a universal sealing mechanism that can adapt to different external connector types, enabling the device to expand its connector options while maintaining consistent waterproof protection through the intermediate sealing structure.

AI summary
A casing 1, a terminal plate 30 that is exchangeably mountable in an opening 23 formed in the casing 1; and a water sealing component 50 disposed around a terminal 31 formed on the terminal plate 30, are provided. A flange 24 is formed inside the opening 23 so as to surround a center of the opening and project toward the center of the opening. When the terminal plate 30 is mounted on the flange 24, an outer side surface of the terminal plate 30 is flush with a surface 21 of the casing in a portion where the opening is formed. With this structure, an electronic device can be obtained that is reliably waterproof and/or dustproof in a connection terminal portion that is exchangeable so as to enhance an expandability.
