Silica Gel Pre-Sealed Connector Assembly for Waterproofing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waterproof connectors require separate customized seal rings or gaskets, leading to increased costs, prolonged development cycles, and reduced assembly efficiency due to mold production of seal rings or gaskets for different types of connectors.
Innovation Solution
A connector design that incorporates silica gel within the cable and mating cavities before assembly, providing pre-sealing that enhances waterproof performance and simplifies assembly by eliminating the need for separate seal rings or gaskets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate customized seal rings or gaskets are assembled after crimping a terminal, then waterproof sealing performance is improved, but manufacturing cost increases, development cycle is prolonged, and assembly efficiency decreases
Solution Approach 1:
The patent merges the sealing function with the terminal structure by integrating a sealing ring directly onto the terminal body. This eliminates the need for separate sealing components and their associated molding, inventory, and assembly steps, thereby improving assembly efficiency while maintaining waterproof sealing performance.
Solution Approach 2:
The integrated sealing ring on the terminal enables a single component to serve multiple functions: electrical connection and waterproof sealing. This universal design allows the same terminal structure to be used across different connector types, reducing development cycles and manufacturing costs while maintaining effective sealing.

AI summary
A connector includes a housing having a mating end and a wiring end opposite the mating end. The wiring end has a first cable passage filled with a first silica gel. A first cable is inserted into the first cable passage and connects to a first terminal installed in the housing. The mating end has a mating cavity filled with a second silica gel at an end adjacent the first cable passage. A mating connector is mated with the connector when inserted into the mating end.
