Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector components face challenges in quickly and safely performing hot insertion or removal without generating prolonged electric arcs, especially at low speeds, leading to potential ablation and other undesirable situations.
Innovation Solution
The connector component employs a design with movable components and force accumulators that deform and restore to facilitate quick connection and disconnection of terminals, reducing the duration of electric arcs through controlled sliding and accumulation of forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the male connector and female connector are inserted or removed at high speed (more than 2 m/s), then the duration of electric arc is reduced, but it is difficult to achieve in actual operation
Solution Approach 1:
The patent introduces movable components (first movable component and second movable component) that can slide relative to the housing and fastening component. These components enable dynamic adjustment of the connection process, allowing the sliding terminals to make or break contact quickly through controlled sliding motion, thereby reducing electric arc duration without requiring high-speed manual insertion or removal.
Solution Approach 2:
The connector is divided into multiple independent components: housing, fastening component, first movable component, and second movable component. Each component performs a specific function in the connection process. The movable components can slide independently to control the contact between sliding terminals and conductive terminals, enabling precise control over the connection and disconnection timing to minimize electric arc duration.
2Speed
If the connector component uses movable components with force accumulators, then the connection and disconnection speed is improved, but the device complexity increases
Solution Approach 1:
The patent combines the force accumulator function with the movable components structure. The force accumulators are integrated into the movable components, which themselves are part of the sliding mechanism. This merging reduces the need for separate actuation mechanisms and simplifies the overall structure while still achieving rapid connection and disconnection through the accumulated force released during sliding.
Solution Approach 2:
The force accumulators automatically accumulate force during the insertion process and then release it to drive the movable components for quick disconnection. This self-service mechanism eliminates the need for external actuators or complex control systems, achieving high-speed operation through the inherent mechanical energy storage and release capability of the accumulators themselves.

Function Achieved in This Case
The solution enables rapid and reliable connection and disconnection of terminals, effectively minimizing electric arc duration and enhancing safety by ensuring quick movement independent of hand speed, thus preventing ablation and other hazards.
Implementation Method 1
the fastening component and the first movable component slide relative to each other, so that the first force accumulator is deformed due to an accumulated force; and when the first stopper is unfastened relative to the first housing, the first force accumulator is restored from the deformation, to drive a second sliding terminal to be connected to the first conductive terminal
