Solution Overview
Problem
Existing transitions for optical fibre cables through partitions are complex to install and lack effective electromagnetic shielding, making them difficult to use in certain applications and vulnerable to electromagnetic interference.
Innovation Solution
A transition comprising a sleeve, a compressible seal, and an electromagnetic shielding tube, where the shielding tube extends from the sleeve, forming a waveguide for the optical fibre cable, providing enhanced shielding and easy assembly, and can be made from conductive materials for efficient installation and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a waveguide is used to shield an optical fibre cable, then electromagnetic shielding performance is improved, but installation complexity increases
Solution Approach 1:
The patent combines the waveguide shielding function with the cable access function into a single integrated transition component. The waveguide is formed as an extension of the cable gland housing, merging two separate functions (shielding and cable securing) into one unified structure, thereby improving shielding performance while simplifying installation.
Solution Approach 2:
The transition component serves multiple functions simultaneously: it acts as a cable gland for securing the optical fibre cable, forms a waveguide for electromagnetic shielding, and provides a sealed enclosure. This multi-functionality eliminates the need for separate shielding components, reducing installation complexity while maintaining effective shielding.
2Reliability
If a compressible seal is used to secure the optical fibre cable, then sealing performance is improved, but assembly complexity increases
Solution Approach 1:
The compressible seal is integrated directly into the housing structure of the transition, eliminating the need for separate seal installation steps. The seal is pre-positioned within the housing, combining the sealing function with the structural component, thereby improving sealing reliability while simplifying assembly.
3Object-affected harmful factors
If the shielding tube is connected to the sleeve, then shielding effectiveness is improved, but manufacturing complexity increases
Solution Approach 1:
The waveguide shielding tube is formed as an integrated extension of the cable gland housing, created in a single manufacturing process. This merging of components improves shielding effectiveness by ensuring proper alignment and connection, while simplifying manufacturing by eliminating separate assembly steps for attaching the shielding tube.
