Blind-Mate Optoelectronic PCB Connector for Replaceable Lasers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The connection of lasers to optoelectronic modules requires significant space and involves replacing the entire module when the laser needs to be replaced, or necessitates two external connections, which is inefficient in terms of space utilization.
Innovation Solution
A connector system comprising a plug-in connector with a first electrical contact and a ferrule holder, allowing for optical and electrical connections to be made sequentially, with a ferrule holder admitting optical fibers and featuring a releasable connection mechanism for easy laser replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the laser is integrated within the optoelectronic module, then the module occupies less space, but the entire module must be replaced when the laser needs to be replaced
Solution Approach 1:
The invention divides the optoelectronic system into separate segments: the optoelectronic module and the laser assembly. The laser is mounted on a separate carrier that can be independently removed and replaced from the module, allowing laser replacement without replacing the entire module while maintaining compact integration.
2Ease of repair
If the laser is attached on the exterior of the module, then the laser can be replaced independently, but two connections are required which occupies valuable space
Solution Approach 1:
The invention merges the optical connection (via ferrule) and electrical connection (via contact) into a single integrated connector assembly. This allows both connections to be made through one interface rather than requiring separate external connections, reducing the space needed for connections while enabling independent laser replacement.
3Ease of operation
If optical and electrical connections are made simultaneously, then the connection process is simpler, but the laser may be damaged during connection due to misalignment
Solution Approach 1:
The invention implements preliminary optical alignment through the ferrule before electrical contact is made. The ferrule guides the laser into proper optical alignment with the optical engine first, and only after this alignment is established does the electrical contact engage. This sequential approach simplifies the connection process while protecting the laser from damage by ensuring proper alignment before electrical connection.

AI summary
The present invention relates to the pluggable connection of an optoelectronic module with an optoelectronic connector assembly from a location exterior to the optoelectronic connector assembly. An optoelectronic module comprises a housing having a proximate end and a rear end in a longitudinal direction; a ferrule arranged adjacent to the proximate end of the housing; an electrical contact arranged adjacent to the proximate end of the housing and stacked with the ferrule in a vertical direction; a biasing members configured to bias the ferrule in the longitudinal direction once pressed; and a guiding member extending in the longitudinal direction and configured to guide the optoelectronic module connected to another optoelectronic module. The optoelectronic connection between the optoelectronic module and the optoelectronic connector assembly has blind mating features.
