Hinged Connector Cover Assembly for Dust Protection and Color Coding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical connectors, such as RJ-type connectors, are prone to contamination from dust and dirt, leading to corrosion and component adhesion issues, and existing color caps are difficult to replace without removing the connector from its mounting location.
Innovation Solution
A cover assembly with a base portion and a cover portion connected by a living hinge, allowing easy installation and removal without disturbing the connector's mounting, and serving as both a dust cover and color cap, with integrated securing features for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a dust cap is provided to protect the connector from contaminants, then protection against dust and dirt is improved, but the cap becomes difficult to remove and replace without removing the connector from its mounting location
Solution Approach 1:
The cap is divided into two functional portions: a dust cap portion that protects the connector from contaminants and a color cap portion that provides identification. These portions are separable, allowing the dust cap to be removed independently for connector access while the color cap remains attached for identification purposes, thus resolving the contradiction between protection and ease of operation
Solution Approach 2:
The dust cap portion is nested within or integrated with the color cap portion, forming a combined assembly that can be attached to the connector. This nested structure allows the smaller dust cap function to be contained within the larger color cap structure, enabling both protection and identification functions in a unified yet separable design
2Loss of information
If color caps are provided for identification, then identification capability is improved, but the caps become difficult to replace in the field without removing the connector
Solution Approach 1:
The cap assembly is segmented into a permanent color cap portion that remains attached to the connector for continuous identification, and a removable dust cap portion that can be independently accessed. This segmentation allows the identification function to be maintained while enabling field replacement of the dust cap without removing the connector or the color cap
Solution Approach 2:
The color cap portion serves multiple functions: it provides identification through color coding, structural support for the overall cap assembly, and a mounting base for the removable dust cap portion. This multi-functionality allows the color cap to remain permanently attached for identification while accommodating the removable dust cap for protection
3Ease of operation
If the connector cavity is left exposed for easy access, then ease of operation is improved, but the connector becomes prone to contamination from dust and dirt
Solution Approach 1:
The dust cap portion is designed as a dynamic, removable component that can be in either a closed position (providing protection) or an open position (providing access). This dynamic design allows the user to open the cap when connector access is needed and close it when protection is needed, thus resolving the contradiction between ease of access and contamination risk
Solution Approach 2:
The protective dust cap portion can be completely removed or taken out from the connector assembly when access is required, rather than requiring the entire connector to be removed. This extraction of the protective element allows full access to the connector while maintaining the option for protection when the cap is reattached

AI summary
A cover assembly (100) is disclosed that can be installed onto and removed from a telecommunications connector (200) without requiring the connector (200) from being removed from its mounted position and without requiring an associated cover plate (120) from being removed from its mounted position. The cover assembly (100) can include a base portion (150) that defines an opening that entirely surrounds a cover portion (110). In one example, the cover portion (110) is attached to the base portion (150) via a living hinge (118). In one aspect, the base portion (150) acts as a color cap while the cover portion (110) acts as a dust cover. In one example, the base portion (150) is provided without a cover portion (110) such that the cover assembly (100) simply acts as a color cap.
