Bayonet Locking Sealing Cap for Connector Media Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing caps for connectors fail to provide adequate protection against media such as dust and water, particularly at the mating face, and often lose functionality over time due to inconsistent sealing force.
Innovation Solution
A detachable sealing cap with a bayonet locking mechanism, featuring a locking cylinder and a docking cylinder with a seal in a circumferential groove, ensuring consistent force application for media-tight sealing, and allowing for stacking and color-coded identification of connector types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a sealing cap is used to protect the mating face of a connector, then protection against media ingress is improved, but the sealing cap can be lost or misplaced during storage and transport
Solution Approach 1:
The sealing cap is designed to be nested within another sealing cap of identical construction. The outer cap receives and retains the inner cap, creating a nested configuration. This ensures that during storage and transport, caps cannot be lost or misplaced, while maintaining their protective function against media ingress.
2Ease of operation
If a sealing cap is detachably fixed to the connector housing, then ease of removal and reattachment is improved, but consistent sealing force is difficult to maintain
Solution Approach 1:
The sealing cap employs a bayonet locking mechanism that provides dynamic, repeatable engagement. The locking means enable the cap to be quickly attached and detached while maintaining consistent sealing force through the mechanical advantage of the bayonet principle, ensuring reliable sealing across multiple cycles of removal and reattachment.
3Reliability
If a sealing cap with locking mechanism is used, then retention and consistent sealing are improved, but device complexity increases
Solution Approach 1:
The sealing cap design segments the locking function from the sealing function. The locking means (bayonet mechanism) are integrated into the cap structure but operate as a distinct functional element, providing reliable retention and consistent sealing force without requiring overly complex overall design. The segmentation allows each function to be optimized independently.

AI summary
The invention relates to a closing cap for the media-tight sealing of a plug face of a plug-and-socket connector, in particular a round plug-and-socket connector, wherein the closing cap (1) can be detachably fastened to a plug-and-socket connector housing (3), and wherein the closing cap (1) comprises means (5, 6) such that the closing cap (1) can be detachably fastened to a further closing cap (1') of identical construction. The closing caps (1) can be stored, for example, stacked one on top of the other on a plug-and-socket connector housing in a switchgear cabinet. This simplifies storage.
