Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a clamping frame with clamping actuator is used to secure the plug connection, then the electrical connection becomes more secure and reliable, but the device complexity increases and the ease of operation decreases
Solution Approach 1:
The patent combines multiple clamping legs into a single integrated clamping frame structure that surrounds the contact socket. This merging approach maintains the secure clamping function while reducing the number of separate components and simplifying the overall device architecture compared to having individual clamping mechanisms for each contact point.
Solution Approach 2:
The clamping frame serves multiple functions simultaneously: it provides mechanical support for the contact socket, applies clamping force through the clamping actuator, and ensures electrical connection security. This multi-functionality reduces the need for separate components and simplifies the device while maintaining reliability.
2Ease of operation
If the contact socket is designed with resilient clamping legs that are open at the top, then the ease of insertion is improved, but the connection security may be insufficient for high-current applications
Solution Approach 1:
The contact socket is pre-designed with resilient clamping legs that are naturally open at the top to facilitate easy insertion. This preliminary configuration allows plug insertion without force before the clamping actuator is engaged, solving the ease of operation requirement while maintaining the capability for secure connection when needed.
Solution Approach 2:
The clamping legs are designed with resilient properties that allow them to dynamically adapt: they remain open for easy insertion, then close and secure when the clamping actuator is engaged. This dynamic behavior satisfies both ease of insertion and connection security requirements for high-current applications.
3Reliability
If excessive force is applied during plug insertion to ensure secure connection, then the connection security is improved, but damage to the printed circuit board or contact socket may occur
Solution Approach 1:
The contact socket is pre-configured with an open-top design that allows the plug to be inserted without force. The secure connection is then achieved through the clamping actuator mechanism rather than insertion force, preventing damage to the printed circuit board while ensuring connection security.
Solution Approach 2:
The clamping actuator serves as an intermediary mechanism that provides the securing force after insertion. Instead of applying excessive force during insertion, the actuator gradually engages and applies controlled clamping force, preventing damage to the printed circuit board while ensuring reliable connection security.

Implementation Method 1
The clamping actuator (80) is designed to move the clamping frame (50) relative to the printed circuit board (10) in a predetermined clamping direction (60) when it is actuated. During this movement, the clamping frame (50) interacts with the first clamping projection (25) and the second clamping projection (27) in such a way that the connector receiving space (130) is narrowed

AI summary
A plug-in contact device for electrically connecting a plug to a socket mounted on a printed circuit board comprises the circuit board and the socket. The socket has a first clamping leg with a first clamping projection and a second clamping leg with a second clamping projection, the first clamping leg being opposite the second clamping leg, and the two clamping legs defining a plug receiving space for receiving the plug. The plug-in contact device includes a clamping frame surrounding the socket and a clamping actuator which, when actuated, moves the clamping frame relative to the circuit board in a clamping direction. The clamping frame interacts with the clamping projections such that the plug receiving space is narrowed when the clamping actuator moves the clamping frame relative to the circuit board in the clamping direction.
