Detachable Receptacle Connector Structure for Replaceable 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, and a connector configuration that facilitates tilting and pivoting for smooth removal and attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a receptacle connector is mounted on a main substrate by soldering, then the connector is firmly fixed and electrically connected, but the main substrate must be replaced to replace the connector, increasing cost and environmental impact
Solution Approach 1:
The invention divides the connector system into three separable components: the receptacle connector (outer shell), the relay connector (inner connector with contacts), and the surface mount connector (substrate-mounted connector). This segmentation allows the receptacle connector to be replaced independently by detaching only the relay connector from the surface mount connector, while leaving the substrate intact. The connector connecting hole in the surface mount connector enables this modular assembly and disassembly.
Solution Approach 2:
The relay connector serves as an intermediary component between the receptacle connector and the surface mount connector. It can be detachably connected to the surface mount connector through the connector connecting hole, allowing the receptacle connector to be coupled to the substrate without direct soldering. This intermediary structure enables easy replacement of the receptacle connector while maintaining reliable electrical connection.
2Reliability
If receptacle connectors are soldered to the main substrate, then electrical connection is secure, but the number of failed connectors is large and replacement is difficult
Solution Approach 1:
The connector system is segmented into replaceable modules where the relay connector can be detached from the surface mount connector through the connector connecting hole. This allows the receptacle connector to be replaced without re-soldering operations, making maintenance easier while maintaining secure electrical connection through the relay connector's contact points.
Solution Approach 2:
The connector system transitions from a static soldered connection to a dynamic detachable connection. The relay connector can be connected and disconnected from the surface mount connector through the connector connecting hole, enabling easy replacement of failed receptacle connectors without permanent attachment, thus improving maintainability.
3Ease of repair
If a detachable relay connector is used, then connector replacement is easy, but the connector structure becomes more complex
Solution Approach 1:
While segmentation into three components (receptacle connector, relay connector, surface mount connector) enables easy replacement, the invention simplifies the overall structure by using a standardized connector connecting hole in the surface mount connector that directly receives the relay connector. This reduces the need for additional complex fastening mechanisms or intermediate components.
Solution Approach 2:
The surface mount connector with the connector connecting hole serves multiple functions: it provides mechanical support for the relay connector, establishes electrical connection through contact points, and enables detachable coupling. This multi-functionality reduces the need for separate components for each function, simplifying the overall structure despite the detachable design.

AI summary
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.
