Solution Overview
Problem
The issue of poor contact and detachment of heat sinks from pluggable assemblies due to outward squeezing during heat transfer, leading to inefficient heat exchange in connector assemblies.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the heat dissipating seat is fixed rigidly to the main body, then the mounting structure is simple and stable, but the heat dissipating seat cannot accommodate outward squeezing during pluggable assembly insertion, resulting in poor contact or detachment
Solution Approach 1:
The sealing member incorporates a floating portion that can move relative to the main body, transforming the rigid fixed connection into a dynamic adjustable connection. This allows the heat dissipating seat to accommodate outward squeezing forces during pluggable assembly insertion while maintaining stable contact through the elastic restoring force of the elastic member.
Solution Approach 2:
The sealing member changes its physical state from rigid to elastic through the incorporation of elastic members. This parameter change allows the sealing member to deform under squeezing forces and then restore its original shape, maintaining reliable contact between the heat dissipating seat and the pluggable assembly.
2Reliability
If the heat dissipating seat is made movable relative to the main body, then contact with pluggable assemblies is improved, but the mounting structure becomes more complex
Solution Approach 1:
The sealing member is designed as a flexible structure with a floating portion that can deform and move. This flexible design allows the heat dissipating seat to adapt to outward squeezing forces while maintaining contact, improving heat exchange efficiency without requiring complex mechanical adjustment mechanisms.
Solution Approach 2:
The elastic member provides self-service by automatically generating restoring force when the floating portion is deformed by outward squeezing. This self-restoring mechanism maintains contact between the heat dissipating seat and pluggable assembly without requiring external control systems or complex actuation mechanisms.
3Stability of the object's composition
If the sealing member is firmly attached to the main body, then structural stability is maintained, but the heat dissipating seat cannot move to maintain contact during pluggable assembly insertion
Solution Approach 1:
The sealing member is segmented into a fixing portion that remains attached to the main body and a floating portion that can move independently. This segmentation allows the fixing portion to maintain structural stability through firm attachment while the floating portion moves to accommodate outward squeezing forces, maintaining contact with the pluggable assembly.
Solution Approach 2:
The floating portion acts as an intermediary between the firmly attached fixing portion and the heat dissipating seat. It transmits the elastic restoring force from the elastic member to the heat dissipating seat, maintaining contact during pluggable assembly insertion while allowing the fixing portion to remain stably attached to the main body.

AI summary
A heat sink assembly and a manufacturing method thereof are provided. The heat sink assembly includes a heat dissipating base and a sealing member. The heat dissipating base includes a main body and a dissipating seat. The main body is mounted to a connector assembly, and an inner surface of the main body defines a passageway space. The heat dissipating seat is placed in the passageway space. The sealing member is provided in the passageway space. The sealing member has a fixing portion which is connected to the inner surface of the main body, and a floating portion which is connected to the fixing portion and the heat dissipating seat and is separated from the inner surface of the main body. Therefore, it can allow the heat dissipating seat to cooperate with contacting and abutting of a pluggable assembly to move relative to the main body, avoid the heat dissipating seat generating interference with the pluggable assembly, in turn attain an effect of promoting mounting firmness.
