Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronics housing connecting devices require manual adaptation and additional components for secure electrical connection of shield conductors to printed circuit boards, leading to increased complexity and cost.
Innovation Solution
A connecting device with a movable cover that applies a spring force to press the uninsulated conductor section against a contact section on the printed circuit board, ensuring secure electrical contact without the need for additional contacting means or manual adaptation, and allowing automatic adaptation to different conductor cross-sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional contacting means (clamping screw) are used to secure the conductor, then the electrical connection reliability is improved, but the device complexity increases
Solution Approach 1:
The cover is designed to perform multiple functions simultaneously: it closes the opening for safety, provides the clamping force through integrated contacting means, and secures the conductor in the receiving space. This merging of functions eliminates the need for separate clamping screws and reduces the overall number of components in the connecting device.
Solution Approach 2:
The cover is transformed from a simple protective element into a multi-functional component that combines the functions of a closure, a clamping mechanism, and a securing element. The contacting means are integrated into the cover structure, allowing a single component to achieve multiple objectives that previously required separate parts.
2Reliability
If manual adaptation is required for secure electrical connection, then the connection reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The connecting device is designed to automatically adapt to different conductor cross-sections through the spring force mechanism. When the cover is closed, the spring force automatically adjusts the clamping pressure to secure the conductor reliably without requiring manual adjustment or adaptation, making the operation simple and intuitive.
Solution Approach 2:
The spring force mechanism allows the clamping pressure to vary automatically based on the conductor size and material properties. This dynamic adjustment of the clamping parameter ensures reliable electrical connection across different conductor types without requiring manual intervention to change connection parameters.
3Stability of the object's composition
If the cover is fixed to the receiving body by screws, then the stability is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The contacting means are integrated directly into the cover structure, eliminating the need for separate clamping screws and additional fastening operations. This integration simplifies the manufacturing process by reducing the number of parts and assembly steps while maintaining the stability and security of the connection.

AI summary
An electronics housing includes: a housing body; and a printed circuit board. The housing body has a connecting device for connecting a conductor, in particular a shield conductor, of a cable to the printed circuit board. The connecting device has a receiving body in which a receiving space with an opening for the conductor is formed. A cover for the opening is provided and is movable between an open position, in which the cover opens the opening for inserting an uninsulated conductor section of the conductor into the receiving space, and a closed position, in which the cover closes the opening at least in sections. The receiving body of the connecting device is disposed such that the printed circuit board is arrangeable with at least one contact section in the receiving space, and, in a closed position, the cover presses the uninsulated conductor section.
