Protected Plug Socket Insertion Aid for Telecommunications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective plugs for distribution devices in telecommunications and data technology are expensive to manufacture and difficult to assemble or disassemble, especially when they have contact legs, which can be damaged during individual contact and are prone to incorrect insertions.
Innovation Solution
A protective plug with an insertion aid made of non-conductive material that mechanically fixes contact legs, ensuring all legs are contacted simultaneously and preventing damage, with a design that includes fork contacts, a U-shaped part, and webs for insulation and stabilization, allowing for easy installation and removal without damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If protective elements are soldered in designs with printed circuit boards, then manufacturing cost is reduced, but the protective elements cannot be replaced
Solution Approach 1:
The protective plug is divided into a housing, an insertion aid, and replaceable protective elements (surge arresters and current fuses). This segmentation allows the protective elements to be independently replaced while maintaining a permanent housing structure, resolving the contradiction between fixed PCB mounting and replaceability.
Solution Approach 2:
The insertion aid serves as an intermediary component that facilitates the insertion and removal of protective elements. It provides a standardized interface between the protective elements and the housing, enabling easy replacement without soldering while maintaining manufacturing efficiency.
2Reliability
If protective elements have contact legs, then they can be mechanically fixed, but the contact legs can be damaged during individual contact and are prone to incorrect insertions
Solution Approach 1:
Multiple contact legs are combined into a single integrated insertion aid assembly. This allows all contact legs to be inserted and contacted simultaneously as one unit, eliminating the risk of individual leg damage and preventing incorrect insertions through standardized geometry.
Solution Approach 2:
The insertion aid acts as an intermediary that protects the contact legs during insertion and removal. It provides a standardized interface that guides proper insertion and prevents damage to the delicate contact legs, resolving the contradiction between mechanical fixation and operational safety.
3Ease of operation
If protective elements are contacted one after another, then individual contact is possible, but the contact legs can be damaged and incorrect insertions occur
Solution Approach 1:
The insertion aid combines multiple contact legs into a single integrated component that is inserted and contacted simultaneously. This eliminates the sequential contact process that risks damage, while maintaining the ability to individually replace protective elements through the standardized interface.
4Reliability
If protective plugs use resilient elements for contact, then contact pressure is ensured, but manufacturing cost increases
Solution Approach 1:
The resilient elements are extracted from the main housing structure and integrated into the removable insertion aid. This allows contact pressure to be maintained through the resilient elements while reducing overall manufacturing cost by simplifying the housing design and enabling modular production.
