Plug Connector Strain Relief with Movable Screw Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plug connector parts for electric vehicle charging systems face issues with securely affixing electrical lines to the housing to absorb and dissipate tensile forces, which can lead to detachment under tension.
Innovation Solution
A plug connector part with a movably arranged strain relief element and an adjusting element that can be actuated to fix the electrical line to the housing in a tension- and torsion-loadable manner, using a screw mechanism for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a clamping connection using a clip is used to affix the electrical line to the housing part, then the electrical line can be fixed to the housing part, but the connection may not sufficiently absorb and dissipate tensile forces, leading to potential detachment under tension
Solution Approach 1:
The strain relief element is designed to be movable relative to the housing part, allowing it to dynamically adjust and absorb tensile forces through controlled movement rather than rigid resistance. This dynamic mechanism enables the connection to withstand tension loads while maintaining reliability.
Solution Approach 2:
The strain relief element acts as an intermediary component between the electrical line and the housing part. It mediates the tensile forces by providing a dedicated load-bearing interface that protects the electrical line connection from direct tension, thereby preventing detachment.
2Ease of manufacture
If housing halves are assembled to clamp the electrical line between them, then the electrical line is fixed in a clamping manner, but the structure becomes more complex and assembly becomes more difficult
Solution Approach 1:
The strain relief function is segmented as a separate, movable element distinct from the main housing structure. This allows the strain relief element to be independently designed, assembled, and adjusted without requiring complex housing half assemblies, thereby simplifying the overall manufacturing process.
Solution Approach 2:
The strain relief element is designed to be self-adjusting through its movable arrangement, automatically positioning itself to provide optimal strain relief without requiring complex adjustment mechanisms or multiple assembly steps. This self-service capability simplifies both manufacturing and assembly.

AI summary
A plug connector part for connecting to a mating plug connector part includes: a housing part on which a plug-in section for a plug-in connection to the mating plug-in connector part is arranged; at least one contact element arranged on the plug-in section so as to make electrical contact with an associated mating contact element of the mating connector part; an electrical line arranged on the housing part and electrically connected to the at least one contact element; a strain relief element movably arranged on the housing part; and an adjusting element that can be brought into operative connection with the strain relief element. Via actuation of the adjusting element, the strain relief element is movable into a position in which the strain relief element fixes the electrical line, relative to the housing part, in a tension-loadable manner.
