Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The miniaturization of electronic products has led to a need for reduced sizes of coaxial cable connectors, resulting in insufficient mating force due to decreased contact area, causing detachment issues and potential damage to electronic products.
Innovation Solution
A flip-cover receptor connector design with a receptor insulator, central terminal, shielding terminal, and metal cover that allows for a reduced height while maintaining secure electrical contact through a pivoting metal cover that forms a shielding loop, preventing longitudinal movement of the RF plate or cable end connector.

If the height of the receptor connector and cable end connector is reduced to meet miniaturization requirements, then the overall size of electronic products is reduced, but the mating force between connectors becomes insufficient due to reduced contact area
Solution Approach 1:
The patent applies the dynamics principle by making the metal cover movable (pivoting/flipping) rather than static. The metal cover transitions from an open state during assembly to a closed fastened state after mating, dynamically changing the contact area and mating force characteristics. This allows the connector to achieve sufficient mating force through the flipping action that increases contact area between the metal cover and RF plate, while maintaining a compact overall height when closed.
Solution Approach 2:
The patent employs dimensionality change by utilizing the flipping motion of the metal cover to transform the contact interface from a limited initial contact point to an extended contact area along the flipping trajectory. This dimensional transformation in the contact area compensates for the reduced overall connector height, ensuring adequate mating force is achieved through the increased effective contact surface between components.
2Reliability
If the contact area between connectors is increased to ensure sufficient mating force, then the reliability of connection is improved, but the overall height of the connector assembly increases
Solution Approach 1:
The patent applies nesting by placing the RF plate and cable end connector within the enclosed space formed by the metal cover and receptor insulator. The metal cover folds over to nest the RF plate securely against the receptor insulator, creating a compact nested structure. This nesting arrangement ensures reliable connection through extended contact area while maintaining minimal overall height, as the contact surfaces are nested within the connector body rather than extending outward.
3Reliability
If a flip-cover structure is added to increase mating force, then the connection reliability is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple functions into the metal cover component: it serves as both a shielding element (forming a shielding loop with the receptor insulator) and a fastening mechanism (flipping to contact and secure the RF plate). By combining the shielding function and fastening function into a single integrated component, the patent improves connection reliability through enhanced mating force while minimizing the increase in device complexity that would result from separate independent components.

AI summary
A flip-cover receptor connector, and a RF (radio frequency) plate cable and a cable end connector used in conjunction therewith are provided. A receptor insulator is provided concavely with a placement space. A metal cover may be forced to rotate pivotally until fastening with the receptor insulator, thereby movement of the RF plate cable or the cable end connector in the placement space of the receptor insulator is restricted. As such, the movement of the RF plate cable or the cable end connector may be restricted, such that it is not easy to leave the placement space of the receptor insulator due to external force impact by fastening the metal cover and the receptor insulator even though height of the flip-cover receptor connector is very small.
