Solution Overview
Problem
Existing electrical connectors face challenges in providing reliable, high-speed, and high-current connections while maintaining stability and ease of assembly, particularly in electronic systems where multiple PCBs need to be interconnected.
Innovation Solution
The electrical connector design includes an elongated housing with signal and power terminals, asymmetric power terminals, locking structures, and retaining members to ensure secure and efficient connections, allowing for high-speed signal transmission and high-current flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If electrical connectors are designed for high-speed signal transmission and high-current flow, then transmission performance is improved, but connection stability and reliability deteriorate due to increased stress and heat generation
Solution Approach 1:
The connector is divided into distinct functional zones: signal terminals for high-speed data transmission, power terminals for high-current flow, and grounding terminals for electromagnetic shielding. Each terminal type is independently optimized and positioned to minimize interference, with signal terminals arranged in rows within insulative housings that provide dedicated channels for each signal path.
Solution Approach 2:
The connector employs asymmetric terminal configurations where power terminals are positioned at specific locations (e.g., outer edges) with different arrangements than signal terminals. The housing structure itself is asymmetric, with locking portions and retaining members positioned to provide enhanced mechanical stability in directions most susceptible to stress from high-current flow and rapid signal changes.
2Reliability
If electrical connectors use complex locking structures and retaining members to prevent disconnection, then connection reliability is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
Multiple retention functions are merged into integrated structures: locking portions are formed as integral parts of the housing rather than separate components, retaining members are embedded within the housing structure, and the housing itself provides both mechanical support and retention features. This reduces the number of discrete parts while maintaining robust anti-disconnection capability.
Solution Approach 2:
The connector design incorporates self-aligning and self-retaining features where the housing structure automatically provides locking and retention functions through its geometry. Locking portions and retaining members are positioned to engage with mating connectors in a way that requires minimal additional fastening operations, allowing the connector to maintain its own connection stability.
3Reliability
If electrical connectors are designed with multiple terminal types and locking mechanisms, then connection reliability is improved, but ease of assembly deteriorates due to increased assembly steps
Solution Approach 1:
The housing structure serves multiple functions simultaneously: it provides mechanical support for all terminal types, integrates locking portions for secure attachment, incorporates retaining members for terminal retention, and provides electromagnetic shielding. This multi-functionality reduces the number of separate components and assembly steps required while maintaining high connection reliability.
Solution Approach 2:
Locking portions and retaining members are pre-positioned and pre-configured within the housing structure during manufacturing. Terminal blocks are pre-attached to the housing with proper spacing and orientation. This preliminary preparation allows for faster final assembly where components are simply engaged rather than fully assembled from individual parts.

AI summary
Electrical connectors configured to provide power and/or high-speed signal connections with a compact form factor. A connector includes a housing holding closely spaced signal terminals arranged in one or more rows and power terminals disposed at row ends. The power terminals extend generally perpendicular to the signal-terminal rows, with blade-shaped mounting portions. The power mating portions can be configured for clamping engagement with corresponding power terminals of a mating connector. The housing includes a slot or tongue portion, with signal terminals lining the slot or tongue portion, with blade-shaped or beam-shaped mating portions. The housing further includes a locking portion configured to receive a portion of a locking member and a holding or retaining member configured to secure the locking member and enhance mechanical attachment. Such a configuration can enable reliable electrical and mechanical coupling between boards or mating connectors without increasing connector height or width.
