Sealed Wire Connector Structure for Unused and Inserted Ports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire connectors fail to effectively isolate the internal space from the exterior environment, regardless of the number of inserted wires, leading to potential exposure and reduced sealing efficacy.
Innovation Solution
A wire connector design comprising a first and second cover with insulating properties, a seal with elastic properties, and a cutting contact for electrical connection, where the seal closes the gap between the covers and ports to ensure isolation, regardless of wire insertion, using pierceable membranes or thin portions for sealing and annular protrusions for contact sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional insulation displacement connector is used without a seal, then the structure is simple and easy to manufacture, but the internal space cannot be isolated from the exterior environment, leading to poor sealing effect
Solution Approach 1:
The patent employs an elastic seal comprising a flexible membrane that can deform to close ports when wires are inserted. The seal includes a body with pierceable membranes or thin portions that allow wire penetration while maintaining sealing capability, effectively isolating the internal space from the exterior environment through flexible film-based sealing mechanisms
Solution Approach 2:
The connector is divided into functional segments: the housing with ports, the elastic seal as a separate component, and the cutting contact. The seal itself is segmented into multiple pierceable membranes corresponding to different ports, allowing independent sealing control for each wire insertion point while maintaining overall structural integrity
2Reliability
If ports remain open for wire insertion, then wire connection is enabled, but the internal space remains exposed to the exterior environment
Solution Approach 1:
The elastic seal is pre-installed in the housing with pierceable membranes positioned at each port before wire insertion. This preliminary placement ensures that sealing capability is already in place, and the seal will automatically close the port after wire penetration, maintaining isolation without requiring additional sealing operations
Solution Approach 2:
The elastic seal automatically performs the sealing function through its inherent elasticity. When a wire is inserted through a port, the pierceable membrane is penetrated by the wire and then elastically deforms to close around the wire, self-adjusting to maintain the sealed state without external intervention or additional components
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
The design achieves a good sealing effect by isolating the internal space from the exterior, ensuring effective electrical connection and protection regardless of the number of wires inserted, through the combination of insulating covers, elastic seals, and a cutting contact for wire connection.
Implementation Method 1
a seal configured to exhibit elasticity and be accommodated in the internal space, wherein in the assembled state, the seal closes a gap between the first cover and the second cover and the seal comprises pierceable membranes or thin portions for closing the ports

AI summary
Provided is a wire connector including a first cover (1) and a second cover (2) that exhibit electrically insulating property. In the assembled state, the first cover (1) and the second cover (2) surround an internal space and define a plurality of ports through which the wire is inserted. Further, the wire connector also includes a seal (3) accommodated in the internal space. In the assembled state, the seal (3) closes the gap between the first cover (1) and the second cover (2), and closes all ports whether there are wires passing through the ports or not, thus isolates the internal space from the exterior by the sealing of the seal (3). In this way, in an assembled state of the first cover and the second cover, the wire connector has a good sealing effect. Further provided is an operation method of the wire connector.
