Waterproof Connector Gluing Plane Coating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional waterproof connectors using waterproof stoppers or washers have high manufacturing costs and low assembly efficiency, particularly for slim-type connectors, as they require additional components that complicate production and assembly.
Innovation Solution
A waterproof connector design featuring a gluing plane coated with waterproof glue, where the isolation base and metal casing form a watertight seal without the need for a waterproof washer or stopper, using a plastic isolation base with exposed terminals and a metal casing with abutting surfaces coated with waterproof glue to fill cracks and prevent moisture ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If waterproof stopper or waterproof washer is mounted in the connector, then waterproof function is improved, but manufacturing cost increases and assembly efficiency decreases
Solution Approach 1:
The patent removes the waterproof stopper or waterproof washer from the connector structure, extracting the problematic component that caused high manufacturing cost and low assembly efficiency. Instead, a waterproof coating layer is applied directly to the inner wall of the metal casing, achieving waterproof function without the need for separate waterproof components.
Solution Approach 2:
The patent merges the waterproof function into the metal casing itself by applying a waterproof coating layer directly to its inner wall. This combines the structural function of the metal casing with the waterproof function, eliminating the need for separate waterproof components and simplifying the overall structure.
2Reliability
If waterproof stopper or waterproof washer is mounted in the connector, then waterproof function is improved, but manufacturing cost increases
Solution Approach 1:
The patent removes the waterproof stopper or waterproof washer from the connector structure, extracting the problematic component that caused high manufacturing cost. Instead, a waterproof coating layer is applied directly to the inner wall of the metal casing, achieving waterproof function without the need for separate waterproof components.
Solution Approach 2:
The metal casing is designed to serve multiple functions: providing structural support, enabling electromagnetic shielding, and providing waterproof protection through the coating layer. This multi-functionality reduces the need for separate components and lowers manufacturing cost.
3Reliability
If metal plate is soldered on the metal casing and waterproof washer is mounted inside, then waterproof function is ensured, but production and assembly speed seriously deteriorates
Solution Approach 1:
The patent removes the metal plate soldering and waterproof washer mounting steps from the production process. The waterproof coating layer is applied directly to the metal casing inner wall in a single step, eliminating the need for multiple separate operations and significantly improving production and assembly speed.
Solution Approach 2:
The waterproof coating layer is applied to the metal casing inner wall during the manufacturing process itself, before the connector is assembled. This preliminary action ensures waterproof function is built-in from the start, eliminating the need for subsequent waterproofing operations during assembly.
4Strength
If openings are provided in the metal casing for connection stability, then connection strength is improved, but waterproof function deteriorates due to moisture penetration
Solution Approach 1:
The waterproof coating layer is applied specifically to the inner wall of the metal casing at locations where moisture penetration is most likely to occur, such as around the openings. This localized waterproofing maintains connection strength while preventing moisture ingress through the openings.
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 design reduces manufacturing costs and improves assembly efficiency by eliminating the need for additional waterproof components, ensuring the electronic device's longevity by preventing moisture penetration through the connector.
Implementation Method 1
a waterproof glue layer 23 is formed by coating the waterproof glue along where the gluing plane 210 and an inner surface of the metal casing 22 are abutted with each other

AI summary
The present invention is to provide a waterproof connector with a gluing plane coated by waterproof glue, which includes an isolation base having a gluing plane formed at a rear end thereof, a plurality of first and second connection terminals each having a rear end exposed out of the gluing plane and an isolation sheet positioned between the first and second connection terminals; a metal casing for allowing the gluing plane to be positioned therein near a back opening thereof while the isolation base is inserted into the metal casing via the back opening; and a waterproof glue layer formed by coating a waterproof glue along where the gluing plane and an inner surface of the metal casing are abutted with each other. Thus, when the waterproof glue is hardened to form the waterproof glue layer, cracks between the metal casing and the isolation base are fully and watertightly filled.
