Round Plug Connector Shielding for Potting-Tight Strain Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard circular connectors have limited design flexibility due to their basic shape, leading to small conductor cross-sections that are susceptible to axial and tensile stresses, and the application of potting compound is hindered by gaps between shielding and contact carrier elements, risking damage to the connector face.
Innovation Solution
Incorporating radial projections on the shielding element to separate the contact carrier and prevent potting compound from entering gaps, allowing connection-side potting without damaging the connector face, and stabilizing conductors against axial and tensile loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radial projections are added to the shielding element to prevent potting compound leakage, then connector face damage is prevented, but device complexity increases
Solution Approach 1:
The shielding element is segmented with radial projections that divide the potential leakage path into separate zones. These projections act as barriers that segment the gap between the contact carrier and outer housing, preventing potting compound from flowing along the gap to the connector face while maintaining the overall integrity of the shielding element.
2Quantity of substance
If conductor cross-section is reduced to fit more contacts in standard circular connectors, then quantity of contacts increases, but conductor strength decreases
Solution Approach 1:
The invention utilizes the radial dimension by adding projections to the shielding element, creating a three-dimensional barrier structure. This radial dimension provides an additional degree of freedom for controlling potting compound flow without affecting the cross-sectional area available for conductors, thereby maintaining conductor strength while achieving the sealing function.
3Ease of manufacture
If gaps are left between contact carrier elements and shielding element, then ease of assembly is improved, but potting compound can leak and damage connector face
Solution Approach 1:
The radial projections on the shielding element act as an intermediary barrier between the gap (which allows easy assembly) and the connector face (which must be protected from potting compound). This intermediary structure permits the gap to remain open for assembly purposes while simultaneously blocking the harmful flow of potting compound toward the connector face.
