Orthogonal Receptacle Cage Mounting for Shorter High-Speed Signal Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional receptacle assemblies on printed wiring boards often result in signal degradation due to longer signal transmission distances, especially for ultrahigh-speed signals, and incur increased costs with the use of cables for signal transmission.
Innovation Solution
A receptacle assembly with connectors and cages mounted orthogonally to the substrate face, allowing for shorter signal paths and direct electrical connections via patterns on the substrate, utilizing flanges, pins, and connecting panels for secure mounting and reduced crosstalk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If receptacles are arranged with insertion-extraction direction parallel to the face of the printed wiring board, then the structure is simple and easy to manufacture, but the signal transmission distance becomes long causing signal degradation
Solution Approach 1:
The patent changes the mounting orientation of the receptacle assembly from parallel to orthogonal relative to the substrate face. This dimensional change allows the receptacle to be positioned directly over the integrated circuit on the opposite face of the substrate, dramatically shortening the signal transmission path through the substrate while maintaining ease of manufacture through standardized orthogonal mounting configurations.
2Length of stationary object
If cables are used to connect receptacles and integrated circuit, then signal transmission distance is extended, but costs increase due to additional components
Solution Approach 1:
By mounting the receptacle assembly orthogonally to the substrate face, the patent enables direct electrical connection through substrate patterns without requiring external cables. The orthogonal orientation allows the receptacle to be positioned directly over the integrated circuit, and the signal path is routed through the substrate itself, eliminating the need for additional cable components.
Solution Approach 2:
The substrate serves as an intermediary that directly connects the receptacle assembly to the integrated circuit. Instead of using cables as intermediaries, the substrate's internal wiring patterns provide the signal transmission path, reducing component count while maintaining signal transmission capability.
3Adaptability or versatility
If receptacles are positioned at both ends of the printed wiring board, then arrangement flexibility is improved, but signal transmission distance to center integrated circuit increases
Solution Approach 1:
The orthogonal mounting configuration allows receptacles to be positioned at various locations on the substrate face while maintaining short signal paths. By changing from a planar parallel arrangement to a three-dimensional orthogonal arrangement, the receptacle can be positioned directly over the integrated circuit regardless of its location on the substrate, eliminating the distance penalty associated with end-positioned receptacles.

AI summary
An embodiment includes: a connector configured to allow a module substrate of a pluggable module to be inserted to the connector along an insertion-extraction direction Die and configured to be electrically connected to the module substrate; a cage having a cage body configured to accommodate the connector and defines a space in which the pluggable module is guided and inserted along the insertion-extraction direction Die. The connector and the cage body are mounted on a substrate such that the insertion-extraction direction Die is substantially orthogonal to the front side of the substrate and a fixing part for fixing the cage body to the substrate is provided at a rear end edge of the cage body located on the substrate side when mounted on the substrate.
