Rotary Contactor Connector With Guide-Pin Terminal Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing contactor rotary connectors face challenges in accurately positioning relay terminals with connector contacts, leading to unstable connections.
Innovation Solution
The design incorporates a first and second connector with molds, space blocks, and a rotating shaft to stabilize the connection by using a fixed component and contactors that rotate to ensure precise alignment and contact between terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If relay terminals are provided on wing portions of a rotating body without additional positioning structures, then the device complexity is reduced, but the manufacturing precision and connection stability deteriorate
Solution Approach 1:
Guide pins are introduced as intermediary elements that mediate between the rotating body and the connector. These guide pins protrude from the rotating body and fit into corresponding guide holes in the connector, serving as precise positioning features that ensure accurate alignment of relay terminals with connector contacts without complicating the overall device structure
Solution Approach 2:
The positioning function is moved from the two-dimensional plane of the wing portions to a three-dimensional arrangement by extending guide pins perpendicular to the rotating body surface. This dimensional transition allows precise positioning through the depth direction, improving alignment accuracy while maintaining simplicity in the planar structure
2Device complexity
If relay terminals are provided on wing portions of a rotating body without additional positioning structures, then the device complexity is reduced, but the connection stability deteriorates
Solution Approach 1:
Guide pins act as intermediary positioning elements that ensure stable connection by precisely aligning the rotating body with the connector. This intermediary structure prevents misalignment during rotation and maintains consistent contact between relay terminals and connector contacts, thereby improving connection reliability without significantly increasing device complexity
Solution Approach 2:
The guide pins and guide holes structure provides beforehand positioning that prevents misalignment before connection issues can occur. By establishing precise geometric constraints in advance through the pin-hole fit, the system cushions against potential connection instability during operation
