Plug Connector Seal Compression Eliminates Axial Play
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-frequency plug connectors with detent interconnections suffer from axial play, leading to undesired displacements and impaired electrical contact quality, which complicates handling and maintenance.
Innovation Solution
Incorporating detent elements in both connectors that engage and lock in a play-free manner through the elastic compression of a seal, eliminating axial play and ensuring constant contact quality without additional spring components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If spring contact elements are provided to form a detent interconnection, then handling is simplified, but axial play causes undesired displacements and impairs electrical contact quality
Solution Approach 1:
The seal is pre-compressed between the first and second surfaces to generate a restoring force that acts in advance to counteract axial play. This preliminary anti-action ensures that the detent elements engage in a play-free manner, preventing undesired displacements and maintaining constant electrical contact quality while preserving ease of handling through automatic engagement.
2Ease of operation
If minimum axial play is required for detent interconnection, then automatic engagement is achieved, but displacements occur that impair contact quality
Solution Approach 1:
The seal's compression state is changed as a parameter to generate a restoring force. By compressing the seal between the first surface ( groove or shoulder) and the second surface (bevel), the physical state of the seal changes from relaxed to compressed, creating elastic restoring force that eliminates axial play and ensures play-free engagement while maintaining automatic engagement capability.

Function Achieved in This Case
The solution provides a restoring force that maintains a defined position between connectors, enhancing electrical contact quality and ease of handling by eliminating play-induced displacements, thus ensuring consistent performance.
Implementation Method 1
the seal (8) is compressed in an axial direction between a first surface (11) and a second surface (12), in the plugged-together state, wherein the first connector (4) and the second connector (6) are pushed apart in an axial direction and counter to the joining direction by a restoring force of the compressed seal (8)
