Plug Connector Positioning for Transceiver Module Width Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing transceiver module configurations in optical communication systems are limited in the number of modules that can be arranged due to the fixed width dimension of the operation-side end face of the housing, making it difficult to reduce the width of the transceiver modules without compromising their structural integrity and functionality.
Innovation Solution
A plug connector for transceiver modules with a concave portion and positioning features, such as projection and notch combinations, allows for reduced width configurations by eliminating the need for guide units, enabling the module board to be positioned accurately without increasing the module's dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If guide units are used to position the module board, then positioning accuracy is improved, but the width dimension of the transceiver module increases
Solution Approach 1:
The patent removes the guide units from the transceiver module structure entirely. Instead of using separate guide units for positioning, the module board is directly positioned using positioning portions formed integrally with the plug connector, thereby eliminating the width increase caused by additional guide units while maintaining positioning accuracy through the integrated positioning structure.
Solution Approach 2:
The positioning function is merged into the plug connector structure itself. The positioning portions are formed as integral parts of the plug connector body, combining the connector and positioning functions into a single component, which eliminates the need for separate guide units and reduces the overall width dimension.
2Productivity
If the width of transceiver modules is reduced, then the number of modules that can be arranged on the operation-side end face increases, but the structural integrity and functionality may be compromised
Solution Approach 1:
The plug connector integrates multiple functions including positioning, guiding, and electrical connection into a single structure. The positioning portions are formed as integral parts of the plug connector body, which maintains structural integrity while reducing the overall width dimension, allowing more modules to be arranged without compromising reliability.
Solution Approach 2:
The patent applies localized positioning features (positioning portions with specific geometries such as projections and notches) at critical locations on the module board and plug connector. This localized approach provides sufficient positioning accuracy and structural support only where needed, rather than requiring comprehensive guiding structures across the entire module width, thus maintaining reliability while reducing overall dimensions.

AI summary
In a transceiver module, when one end portion of a module board (18) is inserted and connected to a concave portion (16R) of a plug connector (16), a projection portion (16PP) formed on the periphery of the concave portion (16R) of the plug connector (16) is fitted into a notch portion (18PH) as one end surface of the module board (18) comes into contact with an inner peripheral surface that forms the concave portion (16R).
