Terminal Retainer for Modular Wiring Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modular wiring systems for commercial and retail spaces require simpler and more manageable components that can be easily modified and rewired, but existing technologies lack efficient solutions for securely and easily connecting terminal components.
Innovation Solution
A terminal retainer system comprising two electrically insulating components that retain a conductive terminal, allowing for easy assembly and interchangeability in modular wiring systems, with anti-rotation features to prevent misalignment and facilitate quick assembly of plugs and receptacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional hard wiring methods are used, then wiring connections are secure and stable, but installation time is long and labor costs are high
Solution Approach 1:
The terminal retainer is divided into two separate components: a first retainer component that receives the terminal and a second retainer component that secures the first component. This segmentation allows for modular assembly where components can be pre-assembled and tested separately, then quickly installed together, dramatically reducing installation time compared to traditional hard wiring while maintaining connection security.
2Ease of operation
If modular plug-and-play components are used, then installation time is reduced and flexibility is improved, but secure and foolproof connections become difficult to achieve
Solution Approach 1:
The first and second retainer components have asymmetric geometries with specific mating features including protrusions and recesses that only fit together in one orientation. This asymmetric design ensures foolproof assembly by preventing incorrect installation, while still maintaining ease of operation through simple snap-fit or interlocking mechanisms that require minimal skill to assemble securely.
Solution Approach 2:
The terminal is pre-mounted on the first retainer component before final assembly with the second retainer component. This preliminary action allows the terminal to be securely positioned and tested independently, ensuring connection reliability is established before the final assembly step, while maintaining the overall simplicity and quick installation characteristics of modular components.
3Ease of manufacture
If simple terminal retention designs are used, then manufacturing cost is reduced and assembly is simplified, but secure retention of terminal components becomes problematic
Solution Approach 1:
The two retainer components work together as a unified retention system where the first component provides terminal reception and the second component provides securing force. By combining these two simple, easily manufactured components with complementary functions, the system achieves strong terminal retention through their cooperative interaction rather than requiring a single complex retention mechanism.

AI summary
A terminal retainer for a modular wiring system includes a first retainer component made of an electrically insulating material, an internal post protruding from an inner surface of the first retainer component, a terminal made of an electrically conductive material and adapted to be electrically joined to an electrical wire, the terminal having a hole for mounting the terminal on the post, and a second retainer component also made of the electrically insulating material, the second retainer component being adapted to attach to the first retainer component to form the terminal retainer.
