Solution Overview
Problem
Existing connector assemblies face challenges in stably connecting the outer terminal of a coaxial connector to the ground layer of a substrate, leading to unreliable electrical connections.
Innovation Solution
A connector assembly design featuring a coaxial connector with a flange portion and projecting portions, a fixed member with spring and contact portions, and fixing members that securely attach to the substrate, ensuring the outer terminal is stably connected to the ground layer through resilient deformation and perpendicular alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the outer terminal is directly connected to the ground layer without additional fixing structures, then the device complexity is reduced, but the reliability of electrical connection deteriorates
Solution Approach 1:
The fixed member acts as an intermediary component between the outer terminal and the ground layer. It includes a first contact portion that contacts the outer terminal, second contact portions that contact the ground layer, and spring portions that provide resilient pressing force to ensure reliable electrical connection through this intermediate element
Solution Approach 2:
The fixed member is segmented into distinct functional portions: a main portion, first contact portion, second contact portions, and spring portions. This segmentation allows each part to perform its specific function optimally while working together to achieve reliable electrical connection
2Stability of the object's composition
If the connector assembly uses simple fixing structures, then the ease of manufacture is improved, but the stability of connection deteriorates
Solution Approach 1:
The fixed member incorporates spring portions that are resiliently deformable, allowing the connection structure to dynamically adapt to manufacturing tolerances and assembly variations. The spring portions can compress and expand to maintain optimal contact pressure, ensuring stable connection while accommodating real-world manufacturing imperfections
Solution Approach 2:
The spring portions enable parameter changes in the connection system by providing variable pressing force. As the assembly is manufactured and installed, the spring portions compress to a degree that provides the optimal contact force between the outer terminal and ground layer, automatically compensating for variations in assembly parameters

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design achieves a highly reliable electrical connection between the outer terminal and the substrate ground layer, reducing signal reflection characteristics and ensuring stable signal transmission.
Implementation Method 1
The spring portion extends from the main portion and is resiliently deformable. The two second contact portions are apart from each other in the lateral direction. At least one of the two second contact portions is supported by the spring portion and is movable in the predetermined plane. Under the connected state, the spring portion presses the second contact portion against the second receiving portion

AI summary
A connector assembly comprises a coaxial connector, a fixed member and two fixing members. The coaxial connector comprises an outer terminal and a center terminal. The outer terminal has a flange portion and two projecting portions. The flange portion has a first receiving portion and two second receiving portions. The first receiving portion faces forward in a front-rear direction. The fixed member has a main portion, a first contact portion, at least one spring portion and two second contact portions. Under a connected state where the connector assembly is connected to a substrate, the spring portion presses the second contact portion against the second receiving portion while the second contact portion receives reaction force from the second receiving portion by the pressing of the spring portion. The first contact portion is pressed against the first receiving portion along the front-rear direction by the reaction force under the connected state.
