Coaxial Connector Mating Portion Segmentation for Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Coaxial electrical connectors face impedance match issues during mating due to poor guidance of the mating portion into the complementary connector's space, leading to misalignment and assembly challenges.
Innovation Solution
The coaxial connector design includes a central conductor with a centrosymmetrical mating portion comprising a contacting, transitional, and guiding portion, where the transitional portion is larger than the guiding portion and smaller than the mating portion, forming acute angles that guide the complementary connector during assembly, ensuring proper alignment and mating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the mating portion is designed with a simple cylindrical shape, then the manufacturing is easy, but the guidance function during mating is poor leading to misalignment
Solution Approach 1:
The mating portion is segmented into three distinct sections: a guiding portion with a smaller diameter, a transitional portion with intermediate diameter, and a contacting portion with larger diameter. This segmentation allows each section to perform its specific function - the guiding portion provides alignment guidance, the transitional portion facilitates smooth insertion, and the contacting portion ensures proper electrical contact, thereby resolving the contradiction between simple manufacturing and effective guidance.
Solution Approach 2:
The invention introduces dimensional variation along the axial direction of the mating portion by creating different diameter sections. The guiding portion has a smaller diameter than the contacting portion, creating a tapered or stepped profile. This dimensional change provides the necessary guidance function during insertion while maintaining rotational symmetry for easy manufacturing.
2Stability of the object's composition
If the mating portion has a larger diameter throughout, then the contact stability is improved, but the insertion difficulty increases due to poor guidance
Solution Approach 1:
By dividing the mating portion into segments with different diameters, the invention achieves both contact stability and insertion ease. The contacting portion maintains a larger diameter for stable electrical contact, while the guiding portion has a smaller diameter that fits into the complementary connector's contact pieces, providing guidance during insertion and preventing misalignment.
Solution Approach 2:
The guiding portion performs the preliminary action of guiding the mating portion into the correct position before the contacting portion makes full contact. The smaller diameter guiding section enters the complementary connector's contact pieces first, establishing proper alignment, followed by the larger diameter contacting portion that ensures stable electrical connection.
3Manufacturing precision
If the mating portion is made centrosymmetrical, then the manufacturing precision is improved, but the guidance function into asymmetric space is reduced
Solution Approach 1:
The centrosymmetrical mating portion is segmented into sections with different diameters along the axial direction. This maintains rotational symmetry for precise manufacturing while the varying diameter creates a tapered profile that provides guidance during insertion into the asymmetric space of the complementary connector's contact pieces.
Solution Approach 2:
The invention resolves the contradiction by utilizing the axial dimension to create diameter variations. The mating portion maintains rotational symmetry around its central axis for manufacturing precision, while the diameter decreases from the contacting portion to the guiding portion along the axial direction, providing the necessary guidance function during insertion.
