Replaceable Receptacle Connector Assembly for Mounted Substrates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing receptacle connectors, particularly those conforming to USB Type-C standards, are prone to failure and require replacement, which involves replacing the entire main substrate due to soldering, increasing user costs and environmental impact.
Innovation Solution
A mounted substrate design featuring a receptacle connector with a detachable relay connector connected to a surface mount connector, allowing easy replacement without soldering, utilizing a connector configuration with specific edge portions and clearances for smooth detachment and attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If receptacle connector is mounted on main substrate by soldering, then connection reliability is improved, but replacement difficulty increases
Solution Approach 1:
The connector assembly is divided into separate components: the receptacle connector and the surface mount connector are independently replaceable parts connected through a detachable relay connector. This segmentation allows the receptacle connector to be replaced without replacing the entire main substrate, while maintaining reliable connections through the relay connector interface.
2Stability of the object's composition
If receptacle connector is soldered to main substrate, then connection stability is improved, but manufacturing cost increases
Solution Approach 1:
The connector system is segmented into modular components where the surface mount connector with relay connector provides stable electrical connections through detachable interfaces, while the receptacle connector remains separately replaceable. This reduces manufacturing costs by allowing selective replacement rather than entire substrate replacement.
Solution Approach 2:
The relay connector serves as an intermediary component between the surface mount connector and the receptacle connector. It provides stable electrical connections while enabling easy detachment and replacement, thus maintaining connection stability without requiring permanent soldering of the receptacle connector to the main substrate.
3Reliability
If receptacle connector is permanently mounted on substrate, then connection reliability is improved, but environmental impact increases
Solution Approach 1:
The design enables the receptacle connector to be easily detached and replaced when failed, while the surface mount connector and relay connector remain on the substrate. This partial replacement approach reduces waste by allowing recovery and continued use of functional components, thereby reducing environmental impact while maintaining connection reliability through the replaceable receptacle connector.

AI summary
Provided is a mounted substrate and an electronic apparatus each of which can achieve easy replacement of a receptacle connector. A mounted substrate includes: a substrate having a mounting surface; a surface mount connector having an inner surface provided with a contact point, having a connector connecting hole opened along a surface direction of the substrate, and mounted on the mounting surface of the substrate; and a receptacle connector having a plug connection opening to which a plug is connected, the receptacle connector including a relay connector detachably connected to the connector connecting hole. The connector connecting hole has an opening edge portion including a first edge portion placed closer to the mounting surface side in a height direction of the connector connecting hole, and a second edge portion placed opposite from the first edge portion in the height direction. The second edge portion is disposed on a deep side from the first edge portion in a depth direction of the connector connecting hole.
