Modular Test Socket for Optical Modules with Adjustable Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing test sockets for optical modules are inflexible and costly to manufacture, requiring dedicated designs for each shape or size change, making it difficult to achieve high accuracy and adapt to varying optical module types.
Innovation Solution
A modular test socket design featuring a first base plate with adjustable positioning holes and a detachable second base plate that sandwiches the optical module, allowing for precise alignment and easy adjustment of components via etching and hinge mechanisms, enabling accurate positioning within ±50 μm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a monolithic test socket is manufactured by resin molding, shaving, and laser processing, then manufacturing precision can be achieved, but adaptability to different optical module types deteriorates and correction or fine adjustment of positioning components becomes difficult
Solution Approach 1:
The test socket is divided into a first base plate and a second base plate that can be detached from each other. The first base plate includes positioning components, while the second base plate includes engagement components. This segmentation allows the positioning components to be precisely manufactured on the first base plate while enabling easy replacement or adjustment of the second base plate to accommodate different optical module types, thus resolving the contradiction between manufacturing precision and adaptability.
2Manufacturing precision
If a dedicated test socket is designed for each optical module shape, then positioning accuracy is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The first base plate is designed with universal positioning components (positioning holes and positioning protrusions) that can accommodate multiple types of optical modules. The second base plate can be detached and replaced depending on the specific optical module type. This multi-functionality design allows a single first base plate to serve multiple purposes, reducing the need for multiple dedicated sockets while maintaining positioning accuracy through the universal positioning mechanism.
3Ease of manufacture
If the test socket structure is simplified to reduce manufacturing cost, then ease of manufacture is improved, but positioning precision and reliability deteriorate
Solution Approach 1:
By segmenting the test socket into two detachable base plates, the positioning components can be concentrated on the first base plate where high precision is critical, while the second base plate can be manufactured with lower precision requirements. This segmentation allows cost-effective manufacturing overall while maintaining high positioning precision where it matters most, through the precise positioning holes and positioning protrusions on the first base plate.

AI summary
A first base plate includes a plurality of first positioning hole portions, an accommodation portion that accommodates an optical module, a first opening portion, a first pressing portion, and a first engagement portion. A second base plate has a second positioning hole portion that is disposed at a position corresponding to the first positioning hole portion, a second opening portion that is disposed at a predetermined positional relationship with respect to the second positioning hole portion, a second holding portion, a conduction portion, a second pressing portion, a substrate portion, a cover portion, a second hinge portion, and a second engagement portion.
