Multi-Interface Electrical Connector for Confined High Voltage Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors for high voltage switchgear are cumbersome and require significant space, making it difficult to connect two high voltage circuits in confined spaces due to the need for bolt-on connectors and large assemblies.
Innovation Solution
An electrical connector with multiple interfaces featuring a body with perpendicular side interfaces and a connecting pin that uses a press-fit connection to connect louver-type connectors, reducing the space required for connections and eliminating the need for bolt-on connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bolt-on connectors are used to connect high voltage circuits, then reliable electrical connection is achieved, but the connector requires large space and tools for installation
Solution Approach 1:
The connector is divided into separate modular components: a body with female interfaces, side interfaces with male connectors, and a connecting pin. This segmentation allows each component to be compact while maintaining reliable electrical connections through standardized interfaces.
Solution Approach 2:
The connecting pin serves as an intermediary element that bridges the body and side interfaces, enabling electrical connection without requiring traditional bolt-on methods. The pin fits into female connectors and connects to male interfaces, providing a space-efficient connection mechanism.
2Reliability
If traditional connectors are used in confined spaces, then electrical connection is achieved, but installation time increases due to tool requirements
Solution Approach 1:
The connector design enables self-service installation through push-fit or snap-fit connections that do not require external tools. The male interfaces with louver-type connectors can be directly inserted and secured into the body, eliminating the need for bolts, screws, or specialized installation tools.
Solution Approach 2:
The louver-type connectors are pre-formed on the male interfaces during manufacturing, allowing for rapid field installation. The connectors are prepared in advance with the correct geometry and electrical properties, enabling quick connection without on-site fabrication or adjustment.
3Area of stationary object
If multiple interfaces are integrated into one connector, then space efficiency is improved, but device complexity increases
Solution Approach 1:
The body serves multiple functions: it houses female connectors for the connecting pin, provides structural support, offers insulation, and presents multiple side interfaces for electrical connections. This multi-functionality reduces the number of separate components needed while maintaining structural integrity and electrical performance.
Solution Approach 2:
The female connectors are nested within the body structure, with the connecting pin passing through the body to connect the nested female connectors. The side interfaces are integrated into the body's exterior surface, creating a compact nested arrangement that minimizes overall assembly space.

AI summary
An electrical connector having a body, first and second female interfaces, a female connector, one to four side interfaces and a connecting pin. The body has a longitudinal axis with a passage extending between the first and second female interfaces. The side interfaces extend from the body and are substantially perpendicular to the longitudinal axis. The interfaces have a distal end and a bus electrically connected to the female connector. The ends of the connecting pin are adapted to snugly engage louver-type connectors on male interfaces, which are inserted into the first and second female interfaces. The electrical connector is designed to minimize the distance between the first and second ends of the body. The side interfaces of the electrical connector can be designed to accommodate different high voltage connectors.
