Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for connecting the shielding of electric cables to connectors often require additional components, which can be easily lost or forgotten during assembly, complicating the shielding against electric interference signals.
Innovation Solution
A contact element with a sectional electrically conductive wall segment integrated into a cylindrical cable guide part, featuring a toggle lever for easy engagement and disengagement, allows the shielding to be securely connected to the connector without additional components, utilizing an insulating cable guide part with conductive ribs for secure signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an additional separate component is used for electric connection between cable shielding and connector housing, then the shielding connection can be realized, but the component is easily lost or forgotten during assembly
Solution Approach 1:
The patent combines the previously separate contact element with the cable guide part into an integrated unit. The conductive wall segment is embedded within the insulating cable guide part, forming a single component that performs both mechanical guidance and electrical connection functions simultaneously, eliminating the risk of losing separate components during assembly
Solution Approach 2:
The integrated cable guide part performs multiple functions: it provides mechanical guidance for cable insertion, maintains positioning of the cable, and simultaneously establishes electrical connection between the shielding and connector housing through the conductive wall segment, reducing the number of separate components needed
2Device complexity
If a conventional cable guide part without integrated contact element is used, then the structure is simpler, but additional separate components are required for shielding connection
Solution Approach 1:
The patent merges the contact element functionality into the cable guide part by embedding a conductive wall segment within the insulating cable guide structure. This integration reduces the total number of separate components from two (cable guide + separate contact element) to one integrated unit, simplifying the overall connector assembly
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
This solution enables easy and secure connection of the cable shielding to the connector, ensuring effective protection against electromagnetic interference by integrating the conductive wall segment within the cable guide part, simplifying assembly and reducing the risk of lost components.
Implementation Method 1
The ground signal delivered via the cable shielding is forwarded to the surrounding electrically conductive connector sleeve by means of the electrically conductive bulge formed by the two ribs
Implementation Method 2
a cylindrical, non-conductive cable guide part... a contact element with a sectional electrically conductive wall segment integrated into a cylindrical cable guide part
Implementation Method 3
The wall segment is shaped about semicircularly in accordance with the sleeve-shaped cable guide part and provided with a toggle lever that can be inserted into the interior of the cable guide part and engages therein, but advantageously allows an outward tilting movement

AI summary
To connect the shielding of an electric cable to a metallic connector, an electrically non-conductive cable guide part that features a wall segment of an electrically conductive material that needs to be laterally opened sectionally is provided. In this case, the shielding of the electric cable lying in the interior is connected to a corresponding mating connector by means of the wall segment and an electrically conductive connector sleeve surrounding the connector.
