Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector assemblies face interference issues during assembly due to the cage or partitioning plate interfering with the stacked connector when mounted on a circuit board, leading to assembly challenges and reduced heat dissipation efficiency.
Innovation Solution
A connector assembly design featuring a guiding shield cage, a partitioning bracket, and a movable heat sink that allows the heat sink to move between a front and rearward position, avoiding interference during assembly and enhancing heat dissipation by enlarging the heat dissipation range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the partitioning bracket and heat sink are assembled later, then the heat dissipation structure can be integrated, but the partitioning bracket interferes with the stacked connector during assembly
Solution Approach 1:
The heat sink is designed to be movable relative to the partitioning bracket, capable of moving between a front position (before assembly) and a rearward position (after assembly). This dynamic structure allows the heat sink to be positioned out of the way during assembly operations, then moved into its final position to provide heat dissipation, thereby resolving the conflict between integration and assembly ease.
Solution Approach 2:
The heat dissipation system is divided into two main components: the partitioning bracket (fixed structure) and the movable heat sink (detachable component). This segmentation allows the heat sink to be independently positioned and moved, enabling assembly operations to proceed without interference while still achieving integrated heat dissipation functionality when the heat sink is in its final position.
2Loss of energy
If the heat sink is positioned to dissipate heat effectively, then heat dissipation efficiency is improved, but interference with the stacked connector occurs
Solution Approach 1:
The heat sink's position is made dynamic rather than fixed, allowing it to move between a front position during assembly and a rearward position for heat dissipation. This resolves the contradiction by enabling the heat sink to achieve effective heat dissipation positioning only when needed, while being movable out of the way during assembly operations.
3Loss of energy
If the intermediate section extends to between upper and lower receptacles, then heat dissipation range is enlarged, but assembly interference with stacked connector occurs
Solution Approach 1:
The intermediate section (heat sink) is designed with movable capability, allowing it to extend into the space between upper and lower receptacles for enhanced heat dissipation range, while being retractable to a front position that prevents assembly interference. This dynamic positioning resolves the contradiction between maximizing heat dissipation range and minimizing assembly complexity.
Solution Approach 2:
The heat dissipation structure is segmented into a fixed partitioning bracket and a movable heat sink, allowing the heat sink to independently extend or retract. This segmentation enables the heat sink to achieve maximum extension for heat dissipation without permanently increasing assembly complexity, as it can be positioned appropriately during different stages.

AI summary
A connector assembly includes a guiding shield cage, a receptacle connector, a partitioning bracket and a movable heat sink. The receptacle connector is provided to a rear segment of an interior of the guiding shield cage, the receptacle connector has an upper receptacle and a lower receptacle. The partitioning bracket is provided in the guiding shield cage, the partitioning bracket and the guiding shield cage together define an upper receiving space which corresponds to the upper receptacle and a lower receiving space which corresponds to the lower receptacle. The movable heat sink is assembled to the partitioning bracket, the movable heat sink is capable of moving relative to the partitioning bracket between a front position where the movable heat sink is positioned in front of a front end of the upper receptacle a front end of the lower receptacle and a rearward position where the movable heat sink at least partially enters into between the upper receptacle and the lower receptacle.
