Elastic Clip Radiator Fixing for High-Speed Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-speed photoelectric connectors face interference from elastic clips that limit the heat dissipation area and service life due to the need for a large blank area without heat dissipation columns or fins, and the radiator length is fixed, not adaptable to varying heat dissipation requirements.
Innovation Solution
A connector design featuring a cage with parallel insertion chambers, radiators mounted on each chamber, and elastic clips with longitudinal and lateral beams that cross the radiator laterally to secure it, allowing for increased heat dissipation area and adjustable radiator length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the elastic pressing fingers are used to hold the radiator on the cage, then the radiator is securely fixed, but the heat dissipation area is reduced due to the need for a large blank area without heat dissipation columns or fins
Solution Approach 1:
The pressing direction is changed from vertical (downward onto the radiator surface) to lateral (horizontal, pressing the side surfaces). This dimensional change allows the pressing fingers to engage with the lateral surfaces of the radiator rather than requiring a blank area on the heat dissipation surface, thus maintaining heat dissipation area while achieving secure fixation.
2Reliability
If the elastic clip structure is used to hold the radiator, then the radiator is securely fixed on the cage, but the service life is reduced due to interference with heat dissipation
Solution Approach 1:
The pressing action is relocated from the vertical dimension (affecting the heat dissipation surface) to the lateral dimension (pressing side surfaces). This allows the elastic clip to perform its fixation function without interfering with the heat dissipation columns or fins, thereby extending service life while maintaining secure attachment.
3Device complexity
If the elastic clip length is fixed by the cage structure, then the assembly is simple, but the radiator length cannot be adjusted according to different heat dissipation requirements
Solution Approach 1:
The elastic clip is designed with flexible beams that can elastically deform during installation and operation. This dynamic flexibility allows the clip to adapt to different radiator lengths without requiring precise pre-matching, enabling the same clip structure to secure radiators of varying lengths while maintaining a simple overall assembly.
Solution Approach 2:
The elastic clip's dimensional parameters (particularly the length and span of the beams) can be adjusted within a range to match different radiator lengths. The elastic deformation capability allows the clip to accommodate parameter variations in the radiator while maintaining secure fixation, providing adaptability without increasing assembly complexity.

Function Achieved in This Case
The design enhances heat dissipation area and extends the service life of the connector by minimizing the negative impact of elastic clips on heat dissipation and allowing for customizable radiator length based on heat dissipation needs.
Implementation Method 1
a pair of elastic lateral beams connected between the pair of longitudinal beams. The pair of elastic lateral beams cross the radiator in a lateral direction of the cage and press the radiator on the top wall of the insertion chamber

AI summary
A connector comprises a cage having a plurality of insertion chambers arranged in parallel, a plurality of radiators each mounted on a top wall of one of the plurality of insertion chambers, and a plurality of elastic clips each adapted to fix one of the radiators on the top wall of one of the insertion chambers. Each clip has a pair of longitudinal beams and a pair of elastic lateral beams connected between the pair of longitudinal beams. The pair of elastic lateral beams cross the radiator in a lateral direction of the cage and press the radiator on the top wall of the insertion chamber. The pair of longitudinal beams are located at a pair of sides of the radiator opposite to each other in the lateral direction and are locked to the top wall of the insertion chamber.
