Multipole Connector Sealing via Through Hole Injection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multipole connectors lack effective moisture protection, leading to damage and breakages due to moisture transfer along electrical cables, and existing sealing solutions are complex or wasteful.
Innovation Solution
A multipole connector design featuring a containment body with through holes for injecting a sealing substance, which seals the housing cavities and reduces manufacturing complexity and time by allowing a single injection of the sealing substance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sealing substance is injected into each single hollow portion of the connectors, then moisture protection is improved, but the complexity of filling operations increases
Solution Approach 1:
The patent merges multiple separate filling operations into a single operation by providing a common filling chamber that can be accessed through one opening. The sealing substance is injected once into the filling chamber, which then distributes it to multiple hollow portions simultaneously, eliminating the need to fill each hollow portion separately through individual openings.
Solution Approach 2:
The filling chamber serves multiple functions: it acts as a reservoir for the sealing substance, a distribution system to multiple hollow portions, and provides access through a single opening. This multi-functional design eliminates the need for separate filling mechanisms for each hollow portion.
2Reliability
If connectors are entirely wrapped with sealing substance, then moisture protection is improved, but the time and cost to strip and replace sealing substance increases when disconnection is needed
Solution Approach 1:
The patent segments the sealing system into internal hollow portions that are accessible through openings, rather than requiring an external wrap. This allows the sealing substance to be contained within specific chambers that can be accessed and modified independently without affecting the entire connector assembly.
Solution Approach 2:
The patent extracts the sealing substance from an external wrap configuration and places it inside internal hollow portions of the connector. This internal placement allows for easier access through openings and simplifies the process of adding or replacing sealing substance without requiring complete removal from the entire connector surface.
3Ease of manufacture
If conventional connectors without sealing are used, then manufacturing simplicity is maintained, but moisture transfer along cables causes damage and breakages
Solution Approach 1:
The patent nests hollow portions containing sealing substance within the connector structure itself. The hollow portions are integrated into the connector body, with openings providing access to the interior. This nested design incorporates the sealing function within the existing connector geometry without requiring external additions or complex manufacturing processes.

Function Achieved in This Case
The solution provides enhanced moisture protection and simplifies the manufacturing process by ensuring effective sealing with a single injection of the sealing substance, reducing the complexity and time required for sealing operations.
