Busbar Adapter Slideable Cover for Terminal Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Busbar adapters lack a mechanism to protect electrical terminals when a power delivery module is removed, leading to potential damage and maintenance issues.
Innovation Solution
The introduction of a busbar adapter design featuring a post portion, electrical terminal, and a slideably engaged cover, where a spring or lever assembly extends the cover to shield the terminal when the module is removed, preventing exposure and ensuring terminal protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a busbar adapter is designed without a cover mechanism, then the device complexity is reduced, but the electrical terminals are exposed to damage and contamination when the module is removed
Solution Approach 1:
The cover is positioned in advance to cover the electrical terminals before the module is removed. When the module is detached, the cover automatically moves into place to shield the terminals, preventing exposure to harmful factors such as contamination and damage.
Solution Approach 2:
The spring mechanism enables the cover to automatically move and position itself based on the presence or absence of the module. The system self-regulates the cover's position without requiring external control, transitioning between covering and exposed states as the module is installed or removed.
2Object-affected harmful factors
If a cover mechanism is added to protect terminals, then terminal protection is improved, but the ease of operation is reduced due to additional components
Solution Approach 1:
The spring-loaded cover automatically transitions between covering and exposed positions in response to module installation or removal. This self-actuating mechanism eliminates the need for manual operation, maintaining ease of use while providing terminal protection.
Solution Approach 2:
The cover is designed as a dynamic component that can move between different positions (covering and exposed) based on operational conditions. The spring mechanism provides the necessary force for automatic transition, allowing the system to adapt to different states without complex control.
3Object-affected harmful factors
If the cover is always extended to shield terminals, then terminal protection is maximized, but the productivity is reduced due to additional steps for module installation
Solution Approach 1:
The cover dynamically adjusts its position based on the module installation state. During installation, the module pushes the cover inward to expose terminals for connection. After installation, the spring automatically returns the cover to its extended protective position, providing continuous protection without manual intervention.
Solution Approach 2:
The cover is pre-positioned in the extended protective state and only moves inward when necessary during module installation. This preliminary positioning ensures terminals are protected during storage and operation, while the automatic movement mechanism minimizes interference with the installation process.
4Object-affected harmful factors
If a spring mechanism is used to extend the cover, then terminal protection is improved, but the device complexity increases due to additional components
Solution Approach 1:
The spring mechanism provides self-actuating operation, automatically positioning the cover based on the module's presence or absence. This eliminates the need for motors, sensors, or control circuits, maintaining simplicity while achieving automatic terminal protection.
Solution Approach 2:
The spring mechanism extracts the complexity of automatic control from the system, using simple mechanical energy storage and release to achieve the covering action. This mechanical approach is simpler than electrical or electronic control systems would require.

AI summary
An electrical adapter includes a post portion (116, 216), an electrical terminal, and a cover (140, 240). The electrical terminal extends from the post portion (116, 216). The cover (140, 240) is slideably engaged with the post portion (116, 216) to selectively shield the electrical terminal.
