Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional jumper connectors are used to bridge board edge connectors, then electrical connection between circuit boards is achieved, but misalignment due to poor processing quality or position offset causes connection failure
Solution Approach 1:
The conductive terminal is designed with flexible bending sections that allow dynamic adjustment of the attaching portion's position and orientation. This enables the terminal to adapt to misalignments between board edge connectors caused by manufacturing tolerances, ensuring reliable electrical connection even when position accuracy is poor.
Solution Approach 2:
The attaching portion of the conductive terminal can change its spatial parameters (position, orientation, curvature) to match the board edge connector's actual position. The guiding structures constrain these parameter changes within acceptable ranges, allowing the terminal to compensate for manufacturing variations and achieve proper alignment.
2Adaptability or versatility
If the jumper connector uses fixed rigid terminals, then manufacturing is simple, but adjustment for position offset is impossible
Solution Approach 1:
The conductive terminal incorporates flexible bending sections that provide inherent adaptability without complex adjustment mechanisms. The terminal can passively adapt to position offsets through elastic deformation, achieving versatility while maintaining relatively simple structure.
Solution Approach 2:
The guiding structures serve as intermediaries between the rigid body case and the flexible conductive terminal. They transmit and constrain the movement of the attaching portion, enabling controlled adjustment while maintaining structural integrity and simplifying the overall design.
3Manufacturing precision
If the jumper connector allows multi-directional movement for alignment, then position adjustment is achieved, but structural complexity increases
Solution Approach 1:
The guiding structures are divided into multiple independent sections, each responsible for constraining movement in specific directions. This segmentation allows complex multi-directional guidance to be achieved through simple, modular components, reducing overall structural complexity while maintaining alignment accuracy.
Solution Approach 2:
The guiding structures utilize three-dimensional spatial arrangements to achieve multi-directional constraint. By distributing guidance functions across different spatial dimensions, the design achieves precise alignment control without requiring complex two-dimensional mechanisms.

AI summary
A connector assembly and a jumper connector thereof are provided. The jumper connector includes a first jumper connector body case for being coupled to a first board edge connector, a second jumper connector body case for being coupled to a second board edge connector, and conductive terminals. The first and second jumper connector body cases are coupled to each other to form an internal receiving space for accommodating the conductive terminals, and the conductive terminals are movable to correspond in position to the first and second board edge connectors respectively. By such structural design, even if circuit boards incur problems like poor processing quality or position offset, the jumper connector according to the present invention can still effectively bridge and join the board edge connectors on the circuit boards, thereby desirably accomplishing electrical connection between multiple circuit boards on electronic equipment.
