Pre-filled Splice Connector Layered Compound Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing twist-on wire connectors often require a barrier layer between pre-filled compounds to maintain separation, which complicates the manufacturing process and may not ensure effective separation of sealing and conductive functions during application.
Innovation Solution
A twist-on wire connector pre-filled with a sealing compound and a conductive compound arranged in distinct layers, where a natural barrier formed by their interface maintains separation, allowing each compound to perform its intended function without a physical barrier, with the connecting element positioned within the conductive compound layer and the sealing compound extending to the conductor opening.

Engineering Contradiction Analysis
1Reliability
If a barrier layer is added between pre-filled compounds to maintain separation, then the separation effectiveness is improved, but the device complexity and manufacturing complexity increase
Solution Approach 1:
A barrier layer is introduced as an intermediary component between the conductive compound and sealing compound. This barrier layer maintains separation between the two compounds, preventing unwanted mixing while allowing each compound to perform its intended function. The barrier layer acts as a mediator that resolves the conflict between achieving effective separation and maintaining device simplicity.
Solution Approach 2:
The interior of the connector is segmented into distinct regions by the barrier layer, creating separate zones for the conductive compound and sealing compound. This segmentation ensures that each compound remains in its designated area, maintaining functional separation without requiring the compounds to be mixed or combined.
2Reliability
If a barrier layer is added between pre-filled compounds to maintain separation, then the separation effectiveness is improved, but the manufacturing complexity increases
Solution Approach 1:
The manufacturing process is segmented into distinct steps: first filling the connector with the conductive compound, then inserting the barrier layer, and finally adding the sealing compound. This segmentation of the manufacturing process, while adding a step, actually simplifies quality control and ensures proper separation without requiring complex mixing or processing techniques.
Solution Approach 2:
The barrier layer is prepared and positioned in advance before the final assembly is completed. This preliminary action of placing the barrier layer ensures that separation is established early in the manufacturing process, preventing contamination or mixing during subsequent steps and simplifying overall manufacturing control.

AI summary
A splice connector, such as a twist-on wire connector, is pre-filled with a plurality of compounds arranged in a corresponding plurality of layers. When the twist-on wire connector is applied to the electrical conductors, the compounds will generally remain in the plurality of layers to thereby allow each of the compounds to perform a different, intended function.
