Optical Module Unlocking Structure With External Return Spring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optical modules have limited installation space due to the presence of a reset spring inside the connection arm, hindering the improvement of function diversity.
Innovation Solution
An optical module unlocking apparatus with an elastic component disposed on the outer side of the mounting portion, independent of the accommodation area for the circuit structure, allowing the elastic component to deform under external force and restore the unlocking arm, thus increasing the installation space without occupying the circuit board area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a reset spring is disposed inside the connection arm, then the unlocking mechanism can be restored to original position, but the installation space of circuit boards and components is reduced
Solution Approach 1:
The elastic component is extracted from the connection arm structure and relocated to the outer side surface of the mounting portion. This separation removes the space-consuming element from the limited connection arm interior while preserving its restorative function, thereby resolving the contradiction between restoration capability and installation space availability.
Solution Approach 2:
The elastic component is repositioned from a three-dimensional interior space (connection arm) to a two-dimensional surface location (outer side surface of mounting portion). This dimensional transition utilizes previously underused surface area, effectively increasing the accommodation area for circuit boards without compromising the restoration mechanism.
2Ease of operation
If the elastic component is disposed inside the connection arm, then the unlocking function can be achieved, but the volume of accommodation area is limited
Solution Approach 1:
The elastic component is extracted from the connection arm and relocated to the mounting portion's outer side surface. This extraction preserves the unlocking function while eliminating the volume conflict, allowing the connection arm interior to be fully utilized for accommodating circuit boards and components.
Solution Approach 2:
The unlocking apparatus is segmented into distinct functional zones: the connection arm handles unlocking operations, while the mounting portion's outer side surface houses the elastic component. This segmentation separates conflicting functions spatially, enabling both unlocking capability and increased accommodation volume to coexist.
3Ease of operation
If the elastic component extends to the accommodation area, then the unlocking mechanism can be implemented, but the area of circuit board is reduced
Solution Approach 1:
The elastic component is localized to a specific region (outer side surface of mounting portion) that is spatially distinct from the accommodation area. This localized placement ensures that the unlocking mechanism function is fulfilled without the elastic component encroaching on circuit board installation space, resolving the area conflict.
Solution Approach 2:
The elastic component is taken out from the accommodation area and positioned on the mounting portion's outer side surface. This extraction eliminates any potential overlap or interference with circuit board placement, allowing maximum circuit board area while maintaining unlocking functionality.

Function Achieved in This Case
The solution increases the volume of the accommodation area, enhances the area of the circuit board, and improves the types and quantity of components, thereby enhancing the function diversity of the optical module.
Implementation Method 1
the elastic component can deform under the action of the external force, and the unlocking arm moves inwards relative to the housing in the insertion direction under an action of elastic force of the elastic component when the external force disappears

AI summary
This application provides an optical module unlocking apparatus, an optical module, and an optical communication device. The optical module unlocking apparatus includes: a housing, including a base and a mounting portion connected to one end of the base, where the base is provided with an accommodation area for installing a circuit board and a component, and the mounting portion is provided with at least one optical port for connecting an optical cable; an unlocking component, including an unlocking arm movably connected to the housing, where the unlocking arm is provided with an abutment portion for abutting against an elastomer of a cage, and the unlocking component is configured to push the unlocking arm outwards relative to the housing in an insertion direction under an action of external force, to separate the abutment portion from the elastomer; and an elastic component, disposed on an outer side surface of the mounting portion and outside the accommodation area, where two ends of the elastic component are respectively connected to the mounting portion and the unlocking component. This can avoid occupying installation space of a circuit structure, increase a volume of the accommodation area, increase an area of the circuit board, increase types and a quantity of components, and improve function diversity of the optical module.
