Rotating Top-Cover Connector for Vibration-Stable PCB Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In prior art connectors, the top cover lacks constraints, leading to detachment in high vibration environments and poor contact between terminals and circuit boards, as it cannot apply pressing forces on inserted circuit boards, relying solely on terminal elasticity for electrical contact.
Innovation Solution
A connector design featuring a housing with transversely arranged terminal slots, rotatably connected top cover, and elastic buckles that apply pressing force on circuit boards when closed, ensuring stable contact and preventing top cover detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the top cover is separated from terminals and relies only on terminal elasticity for contact, then the structure is simple and easy to manufacture, but the reliability of electrical contact deteriorates in high vibration environments
Solution Approach 1:
The top cover is rotatably connected to multiple first terminals, merging the top cover and terminals into a integrated assembly. This allows the top cover to apply pressing forces on the inserted circuit board while maintaining structural simplicity, resolving the contradiction between ease of manufacture and electrical contact reliability
2Device complexity
If the top cover cannot apply pressing forces on the circuit board, then the device complexity is reduced, but the reliability of electrical contact deteriorates
Solution Approach 1:
The top cover is designed to be rotatable between opened and closed positions, transforming from a static component to a dynamic one. In the closed position, it applies pressing forces on the circuit board through the rotatably connected terminals, ensuring reliable electrical contact without requiring complex pressing mechanisms
3Ease of operation
If the top cover is not constrained to the housing, then the ease of operation is improved, but the reliability deteriorates due to detachment in high vibration environments
Solution Approach 1:
The top cover is rotatably connected to the housing through terminals, allowing it to be easily opened and closed for operation. When closed, the rotational connection constrains the top cover to the housing, preventing detachment in high vibration environments while maintaining ease of operation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances reliability by maintaining electrical contact and preventing top cover detachment in high vibration environments through rotational connection and applied pressing force, ensuring consistent connectivity between terminals and circuit boards.
Implementation Method 1
the terminals can only rely on their own elastic force to make electrical contact with the inserted circuit board

AI summary
A connector includes a housing, multiple first terminals and a top cover. The housing defines multiple first terminal slots arranged and spaced in a transverse direction of the housing. The multiple first terminals are inserted into respective ones of the multiple first terminal slots. The top cover is installed on a top of the housing and is rotatably connected to the multiple first terminals. The top cover is rotatable between an opened position and a closed position.
