Connector Cage Structure for Insertion-Activated Heat Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector systems require multiple components, such as spring clips, to achieve an adequate thermal connection between the connector and the heat sink, which can be difficult to handle and occupy significant space.
Innovation Solution
An interface module with a movable cage portion that transitions from a non-thermal contact position to a thermal contact position upon connector insertion, utilizing a floating portion with apertures for improved thermal interface without additional heat sinks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If spring clips are used to press the heat sink and cage together to increase thermal contact, then thermal connection efficiency is improved, but device complexity and difficulty of handling increase
Solution Approach 1:
The patent combines the heat sink and cage into a single integrated component, eliminating the need for separate spring clips to press them together. The integrated design maintains thermal contact through the inherent structural connection while removing the complexity of additional fastening components.
Solution Approach 2:
The patent removes the spring clips from the system entirely by integrating their function into the cage structure itself. The cage is designed with features that directly maintain thermal contact with the heat sink without requiring separate fastening elements.
2Temperature
If a large heat sink is used to dissipate heat from the connector, then heat dissipation capability is improved, but volume occupied within the module increases
Solution Approach 1:
The patent merges the heat sink with the cage structure, creating an integrated component that performs both mechanical support and thermal management functions. This integration eliminates the need for a separate large heat sink volume while maintaining effective heat dissipation through the combined structure.
Solution Approach 2:
The cage is designed to serve multiple functions: mechanical support for the connector, guidance of the connector during insertion, and thermal management through integrated heat dissipation features. This multi-functionality reduces the overall volume required compared to separate dedicated components.

AI summary
There is provided an interface module (200), comprising: an interface (208) for connection with a signal connector (250); a cage (206) for guiding the signal connector towards the interface; and a heat sink (202). The cage (206) comprises a cage portion (212) that is configured to move from a first position to a second position upon insertion of the signal connector (250) into the cage. In the first position, the cage portion is not in thermal contact with the heat sink; when in the second position, the cage portion is in thermal contact with the heat sink. The cage portion (212) comprises one or more apertures (218).
