Pluggable Transceiver Housing With Elastic Pressing Tabs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional housing structures for pluggable transceiver modules face difficulties in assembling components and lack a secure mechanism to firmly fix light-guiding members, leading to potential deviation under external forces.
Innovation Solution
Incorporating elastic pressing tabs on the enclosure to elastically press against the outer side surfaces of light-guiding units, ensuring a stable and firm connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple fixing components (fixing block, clamping plates, bottom plate, back plate, fixing frame) are used to assemble the base and light-guiding members to the cover, then the connection strength is improved, but the device complexity and assembly difficulty increase significantly
Solution Approach 1:
The patent integrates multiple fixing functions into a single enclosure structure by incorporating elastic pressing tabs directly on the enclosure. This consolidates the functions previously performed by separate fixing blocks, clamping plates, bottom plates, back plates, and fixing frames into one unified component, thereby reducing assembly complexity while maintaining connection strength.
Solution Approach 2:
The enclosure is designed with multi-functionality by integrating the elastic pressing tabs directly onto it. The enclosure now simultaneously serves as the housing structure and the fixing mechanism, eliminating the need for separate fixing components and simplifying the overall assembly process.
2Device complexity
If traditional fixing structures are used without additional securing mechanisms, then the device complexity is reduced, but the light-guiding members are not firmly fixed and may deviate under external force
Solution Approach 1:
The enclosure features localized elastic pressing tabs at specific positions where light-guiding members need securing. This local quality enhancement provides targeted fixing reliability at critical interfaces without requiring complex overall structural changes, maintaining simplicity while improving reliability where needed.
Solution Approach 2:
The elastic pressing tabs provide dynamic fixing capability by using elastic deformation to accommodate slight variations in assembly tolerances and to maintain constant contact pressure on the light-guiding members. This dynamic characteristic ensures reliable fixing without rigid, complex mechanical constraints.
3Reliability
If elastic pressing tabs are added to the enclosure to secure light-guiding units, then the fixing reliability is improved, but the manufacturing complexity increases
Solution Approach 1:
The elastic pressing tabs are integrated directly into the enclosure structure, combining two manufacturing processes into one. The tabs are formed as part of the enclosure molding or fabrication process, eliminating the need for separate manufacturing and assembly steps for fixing components, thus maintaining manufacturing ease while improving fixing reliability.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The elastic pressing tabs provide a secure and stable connection between the light-guiding units and the enclosure, preventing deviation and improving handling and assembly efficiency.
Implementation Method 1
an enclosure (3) enclosing the assembled insertion base (1) and light-guiding units (2) therein. The enclosure (3) is provided on two lateral sides with a plurality of inward protruded elastic pressing tabs (31) for elastically pressing against lateral outer surfaces of the two light-guiding units (2)

AI summary
A housing structure for pluggable transceiver module includes an insertion base, at least two light-guiding units separately connected to two lateral sides of the insertion base, and an enclosure enclosing the insertion base and the light-guiding units therein. The enclosure is set on two lateral sides with a plurality of inward protruded elastic pressing tabs for elastically pressing against lateral outer surfaces of the two light-guiding units. When the insertion base and the light-guiding units have been enclosed in the enclosure, the elastic pressing tabs on the enclosure further elastically press against the outer side surfaces of the light-guiding units to ensure more stable and firm connection of the light-guiding units to the enclosure.
