Innovation Solution
A gel-sealed perimeter and cable locking mechanism for insulation piercing connectors, featuring a reinforced top section, to create a watertight barrier and secure cable placement, enhancing durability and simplifying installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional connector designs are used, then assembly process is simple, but environmental protection against moisture and contaminants is inadequate
Solution Approach 1:
The enclosure is divided into a two-part structure with separate cover and base portions that can be independently assembled. The gel seal is applied in grooves on specific surfaces, creating modular sealing zones that protect different areas of the connector while maintaining simple assembly procedures.
Solution Approach 2:
A gel seal acts as an intermediary substance between the enclosure components and the external environment. The gel is applied in peripheral grooves to create a flexible sealing barrier that blocks moisture and contaminants without requiring complex mechanical sealing mechanisms.
2Object-affected harmful factors
If gel seal is applied directly to connector, then sealing effectiveness is improved, but connector functionality is compromised
Solution Approach 1:
The gel seal is extracted from direct contact with the connector by positioning it in peripheral grooves on the enclosure surfaces. This separation allows the gel to provide effective sealing against moisture and contaminants while leaving the connector and its electrical functions completely unaffected.
Solution Approach 2:
The gel seal is strategically placed in peripheral grooves at specific locations around the enclosure where sealing is most needed. This localized application provides effective protection at the boundaries while leaving the central connector area free from gel contact, maintaining both sealing effectiveness and connector functionality.
3Stability of the object's composition
If cable locking mechanism is added, then cable stability is improved, but installation time increases
Solution Approach 1:
The cable locking mechanism is merged with the enclosure structure itself, using the cover and base portions to provide both protection and cable retention. The gel seal and cable locking functions are combined in a single integrated assembly process, allowing installers to secure cables while closing the enclosure in one continuous action rather than as separate steps.

AI summary
Disclosed is an enclosure (100) for insulation piercing connector (306). The enclosure (100) includes a first cover portion (202) and a second cover portion (206), designed to provide environmental barrier for insulation piercing connectors (IPC). The first cover portion (202) features a first inner surface (202a) with a peripheral groove (202b) extending along its edges and a clamping structure (204) on the inner surface, which securely holds multiple cables (304a-304n) connected via the IPC (306). The second cover portion (206), hingedly connected to the first, includes a second inner surface (206a) with a matching peripheral groove (206b) along its edges. The first and second peripheral grooves (202b, 206b) are configured to accommodate a gel sealant (302) that forms watertight environmental barrier around the enclosure (100), protecting the IPC and associated cables from contaminants and environmental stressors. This design ensures durability, reliability, and effective protection for electrical connections in outdoor settings.
