Waterproof Socket Assembly With Multi-Level Sealing Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waterproof sockets suffer from poor sealing and structural design, leading to issues such as water ingress causing short circuits and fires, particularly in outdoor and humid environments.
Innovation Solution
A three-level sealing mechanism is implemented using a spring clip, insulating sleeves, and a waterproof ring, along with a protection film and sealing ring, to enhance the waterproofing and structural integrity of the socket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple waterproof cover is arranged on one side of the socket, then the structure is simple and easy to manufacture, but the waterproof performance is insufficient and water can still ingress causing short circuits
Solution Approach 1:
The waterproof structure is divided into multiple independent sealing components: a sealing ring at the socket body opening, insulating sleeves at each terminal penetration point, and a waterproof cover with integrated sealing features. This segmentation allows each component to address specific waterproofing needs, achieving comprehensive protection while maintaining manufacturing simplicity.
Solution Approach 2:
The insulating sleeves are nested within the terminal structures, with the sealing ring nested at the socket body opening, and the waterproof cover enclosing the entire assembly. This nested arrangement creates multiple concentric sealing barriers that prevent water ingress without requiring complex external structures.
2Reliability
If existing waterproof structures are used with sealing sleeves inside or outside the shell, then some waterproof protection is provided, but the sealing is insufficient and safety problems persist in humid environments
Solution Approach 1:
Different sealing solutions are applied to different locations based on their specific waterproofing needs: a sealing ring made of elastic material is used at the socket body opening where circular sealing is needed, while insulating sleeves made of waterproof insulating material are used at terminal penetration points where both insulation and waterproofing are required. This localized approach ensures optimal sealing at each critical point.
Solution Approach 2:
The waterproof structure combines multiple materials with complementary properties: the sealing ring uses elastic material for flexible sealing, the insulating sleeves use waterproof insulating material to provide both electrical insulation and water barrier functions, and the waterproof cover uses waterproof material to enclose the entire assembly. This composite material approach creates a multi-layered defense against water ingress.
3Reliability
If insulating sleeves are added to seal and fix terminals, then waterproof performance is improved, but the device complexity increases with more components
Solution Approach 1:
The insulating sleeves serve multiple functions simultaneously: they provide electrical insulation to prevent short circuits, act as waterproof barriers to prevent water ingress at terminal penetration points, and serve as structural elements that can be secured with sealing rings. This multi-functionality reduces the need for separate components, maintaining simplicity while achieving comprehensive waterproofing.
Solution Approach 2:
The waterproof cover is merged with the sealing structure, integrating the cover function with the sealing function into a single component. The insulating sleeves are merged with the terminal structures, combining insulation and waterproofing in one element. This merging reduces the total number of separate components while maintaining effective waterproof sealing.
