Optical Connector Receptacle Mounting Structure for Stable Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mounting structures for optical connector receptacles in metal housings often fail to provide stable fixation, leading to potential tilting or instability, especially in high-bandwidth applications like 400G optical communications.
Innovation Solution
A mounting structure with abutment structures and extending elements that lean against the wall of the through hole and the optical connector receptacle, providing balanced support and an average force for stable fixation, comprising a main plate, side plate portions, and elastic members to secure the receptacle within the metal housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional mounting structure is used to fix the optical connector receptacle in the through hole, then the installation is simplified, but the fixation stability is insufficient causing tilting
Solution Approach 1:
The mounting structure is divided into multiple functional components: a main body portion with abutment structures for lateral support, extending elements for depth positioning, and elastic members for securing. This segmentation allows each component to address specific stability issues while maintaining overall installation simplicity.
Solution Approach 2:
The mounting structure is designed to be nested within the through hole of the metal housing, with the main body portion positioned in the through hole and the extending elements protruding into the receptacle cavity. This nested arrangement provides stable fixation without complicating the installation process.
2Device complexity
If the mounting structure uses simple fixation, then the device complexity is reduced, but the reliability of fixation is compromised
Solution Approach 1:
Different portions of the mounting structure have specialized features tailored to their functions: the main body portion has abutment structures for lateral support against the housing wall, while the extending elements have positioning features for depth control. This local differentiation enhances reliability without requiring overall structural complexity.
Solution Approach 2:
The elastic members provide dynamic adjustment capability, allowing the mounting structure to adapt to manufacturing tolerances and assembly variations. This dynamic feature enhances fixation reliability while keeping the overall structure relatively simple.
3Ease of operation
If the optical connector receptacle is loosely fixed, then the ease of operation is improved, but the tilting prevention capability deteriorates
Solution Approach 1:
The abutment structures are positioned to provide counterbalancing support forces that prevent tilting in multiple directions. The extending elements provide counteracting positioning forces that maintain the receptacle in the correct orientation, effectively counterbalancing potential tilting moments while allowing easy installation.

AI summary
The present invention provides a mounting structure of an optical connector receptacle for fixing the optical connector into a through hole of a metal housing. The mounting structure has a main plate leaning against a first surface of the receptacle, and a pair of side plate portions leaning against two second surfaces respectively connected to the first surface. Each side plate portion comprises a first side plate connected to the main plate, a connecting plate having one side connected to the first side plate, and a second side plate connected to another side of the connecting plate so that an indentation structure is formed, wherein the first side plate or the second side plate has a first extending element lean against a housing of the receptacle. In another embodiment, an optical connector module comprises the mounting structure and the optical connector receptacle.
