Coaxial Connector Plug and Receptacle with Suction-Proof Slit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Coaxial connector devices with slits in the ground-connection contact conductor are difficult to stably suction during mounting due to air entering through the slit, leading to unstable suction by suction nozzles.
Innovation Solution
A coaxial connector plug and receptacle design featuring a tubular outer conductor with a slit and a lid member that blocks air entry, allowing stable suction by a suction nozzle through the integration of a projection in the insulator to prevent air from entering the slit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a slit is provided in the ground-connection contact conductor to enable easy insertion of the mating connector, then the ease of operation is improved, but the stability of suction during mounting deteriorates due to air entering through the slit
Solution Approach 1:
The outer conductor is divided into two functional parts: a slit portion that enables easy insertion of the mating connector, and a suction-proof portion that prevents air from entering during suction mounting. This segmentation allows each part to fulfill its specific function without compromising the other.
Solution Approach 2:
Different regions of the outer conductor are given different properties: the lower portion has a slit for ease of insertion, while the upper portion maintains structural integrity to prevent air entry during suction. The insulator also has a localized projection that specifically blocks the slit during suction without affecting insertion.
2Ease of operation
If the ground-connection contact conductor is made deformable by providing a slit, then the ease of operation is improved, but the reliability of suction mounting deteriorates
Solution Approach 1:
The outer conductor is divided into a deformable slit portion for easy insertion and a rigid suction-proof portion for reliable mounting. The insulator's projection acts as a temporary barrier during suction, separating the insertion function from the suction function.
Solution Approach 2:
The insulator projection is pre-positioned to block the slit before suction occurs. This preliminary action prevents air from entering the outer conductor during suction, ensuring mounting reliability while maintaining the slit's insertion advantage.
3Ease of operation
If air can enter the outer conductor through the slit during suction, then the ease of insertion is improved, but the productivity of mounting deteriorates due to unstable suction
Solution Approach 1:
The outer conductor is segmented into insertion-friendly and suction-proof zones, allowing the mounting process to proceed without suction failures that would reduce productivity.
Solution Approach 2:
The insulator projection, which could be seen as an additional component increasing complexity, actually converts the harmful effect of air leakage into a beneficial sealing mechanism that ensures stable suction and efficient mounting.
