Optical Module Reinforcing Members for Abrasion-Resistant Cage Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The electroplated coating on optical modules peels and scratches due to interaction with elastic pieces during locking and unlocking, leading to connection instability and potential deformation failures.
Innovation Solution
The optical module features reinforcing members at its mounting portions, which are clamped with locking tongues of the cage, and an unlocking member that elastically deforms the locking tongues to facilitate smooth insertion and removal, reducing abrasion and enhancing connection stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the optical module uses die-cast shell with electroplated coating for locking portions, then the shell has good strength and appearance, but the electroplated coating peels and scratches during locking and unlocking operations
Solution Approach 1:
The locking portion is segmented into two functional parts: the shell body (which provides structural strength) and the locking portion (which interacts with the elastic piece). By separating these functions, the locking portion can be made of a different material that is resistant to scraping and deformation, while the shell body maintains its die-cast construction for strength and appearance.
Solution Approach 2:
The locking portion is made from a composite or different material than the shell body. Specifically, the locking portion can be made from a material that is more resistant to scraping and deformation, such as a harder alloy or a material with different mechanical properties, while the shell body remains die-cast for structural integrity.
2Ease of operation
If the elastic piece scrapes against the locking portion during locking and unlocking, then the optical module can be easily locked and unlocked, but the electroplated coating peels and the locking portion deforms
Solution Approach 1:
The material parameters of the locking portion are changed to be more resistant to scraping and deformation. By selecting a material with higher hardness, better wear resistance, or different mechanical properties, the locking portion can withstand the scraping action during locking and unlocking operations without deforming or causing coating peeling.
3Ease of manufacture
If zinc alloy shell is used for the optical module, then the shell has good casting properties and strength, but the position where electroplated coating peels is pulverized after long-term use
Solution Approach 1:
The locking portion has different material properties than the rest of the zinc alloy shell. By applying a different material or surface treatment specifically to the locking portion, it gains enhanced resistance to scraping and deformation, while the rest of the shell maintains its zinc alloy casting properties for ease of manufacture and overall strength.

AI summary
This application relates to the technical field of optical communication, and in particular to an optical module and an optical transceiver connection assembly. The optical module includes a shell and mounting portions arranged at two opposite sides of the shell. The mounting portions are each provided with a reinforcing member. An unlocking member is further slidably connected in the shell. The shell is pluggable into a cage and clamped with locking tongues of the cage through the reinforcing members. The unlocking member is capable of undoing the clamping of the locking tongues to the reinforcing members. In this way, abrasion at locking positions can be reduced, thereby improving the connection stability.
