Integrated Metal Connector Casing for Ground Accuracy and Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors for camera modules, such as on-vehicle camera modules, face issues with insufficient strength, positional accuracy, increased components, and assembly complexity due to welding of outer conductors, leading to potential damage and inefficiencies.
Innovation Solution
A connector with a metal casing that integrates a ground terminal part and a fitting part, enhancing strength and accuracy by eliminating gaps and reducing assembly steps through integral formation, with a cylindrical shape for aligned or intersecting insertion directions and a cover member for secure joining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ground terminal part and fitting part are joined by welding, then electrical connection is achieved, but strength is insufficient and positional accuracy varies
Solution Approach 1:
The ground terminal part and fitting part are integrated into a single integral metal casing structure, eliminating the need for separate joining operations. This merging of components ensures both strong mechanical connection and reliable electrical continuity without the weaknesses of welded joints.
2Reliability
If the ground terminal part is joined to the casing by welding, then electrical connection is established, but the number of components increases
Solution Approach 1:
The ground terminal part and fitting part are merged into a single integral metal casing, reducing the number of separate components. This integration maintains electrical connection reliability while simplifying the overall device structure and reducing assembly complexity.
3Reliability
If welding is used to join the ground terminal part and fitting part, then electrical connection is achieved, but assembly time increases
Solution Approach 1:
The ground terminal part and fitting part are manufactured as a single integral component, eliminating the welding process entirely. This integration significantly reduces assembly time and steps while ensuring reliable electrical connection through the continuous metal structure.
4Reliability
If the ground terminal part and fitting part are joined by welding, then connection is achieved, but gaps are formed and ground performance deteriorates
Solution Approach 1:
The ground terminal part and fitting part are formed as a single integral structure, eliminating gaps that would otherwise be created by joining operations. This ensures high manufacturing precision and optimal ground performance through continuous electrical pathways.
