QSFP Plug Assembly Embedding Portions Cable Radiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing plug assemblies for QSFP interfaces experience increased radiation losses due to exposed copper foils from peeled-off insulation layers of external cables, leading to reduced transmission capacity and interference with other devices.
Innovation Solution
A plug assembly design that embeds and fastens external cables directly using upper and lower embedding portions and an external interface, eliminating the need to peel off insulation layers and minimizing radiation losses by maintaining the cables within heat-shrinkable tubes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If insulation layers of external cables are peeled off to shorten outer diameter dimensions, then the cables can be integrated into the QSFP space, but copper foils are exposed causing increased radiation losses and electromagnetic interference
Solution Approach 1:
The patent introduces an intermediary structure (the cover assembly with embedding portions) that mediates between the cable insulation layer and the QSFP interface. This intermediary allows the cable to be secured without peeling the insulation, thus preventing copper foil exposure while achieving proper integration. The embedding portions act as intermediaries that hold the cables in place through the insulation layer intact.
2Ease of manufacture
If insulation layers of external cables are peeled off to integrate cables into QSFP space, then cable integration is achieved, but electromagnetic fields are dissipated causing energy loss and interference with other devices
Solution Approach 1:
The cover assembly serves as an intermediary structure that facilitates cable integration without requiring insulation removal. The embedding portions in the cover provide a mechanism to secure cables while maintaining their insulation layers, thus preventing electromagnetic field dissipation and interference with other devices.
Solution Approach 2:
The patent utilizes the cable's existing insulation layer (a flexible shell) as the protective element rather than removing it. The embedding portions are designed to work with the insulation layer intact, using it as a flexible shell that can be accommodated within the cover structure without compromising cable integration or causing electromagnetic interference.
3Ease of manufacture
If heat-shrinkable tubes are used to integrate external cables, then cables can be assembled to covers, but the assembly process becomes complex requiring multiple components
Solution Approach 1:
The patent merges the functions of cable securing and cable protection into a single integrated structure - the cover assembly with embedding portions. Instead of using separate heat-shrinkable tubes and assembly mechanisms, the embedding portions are directly formed as part of the cover structure, combining multiple functions into one component and simplifying the overall assembly process.

AI summary
A plug assembly includes a lower cover and an upper cover. The lower cover has two lower lateral walls and a lower rear wall. A top surface of a lower portion of the lower cover, the two lower lateral walls and the lower rear wall surround a lower accommodating space. The lower accommodating space has at least one lower embedding portion. The upper cover is assembled to the lower cover. The upper cover has two upper lateral walls and an upper rear wall. A bottom surface of an upper portion of the upper cover, the two upper lateral walls and the upper rear wall surround an upper accommodating space. The upper accommodating space is combined with the lower accommodating space to form an accommodating space. The upper accommodating space has at least one upper embedding portion disposed corresponding to the at least one lower embedding portion.
