Pump Connector Housing for Flexible Cable and Plug Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pump units with electric drive motors face challenges in easily adapting to either plug connector or terminal connections for electric supply, lacking a flexible and safe solution that meets electrical standards.
Innovation Solution
A pump unit design featuring a separate connector housing with a mating plug connector and electrical connection terminals, allowing for either plug connector or terminal connections, with a removable cover for safety and compliance with electrical standards, and a fastening mechanism for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pump unit is equipped with a fixed electrical plug connector for easy connection, then ease of operation is improved, but adaptability to different connection types (terminal connection vs. plug connection) deteriorates
Solution Approach 1:
The electrical connection system is divided into two separate components: a fixed plug connector integrated into the pump unit housing, and a separate connector housing containing the mating plug connector and electrical connection terminals. This segmentation allows the pump unit to maintain its fixed plug connector for ease of connection while the separate connector housing provides adaptability to accommodate both plug connections and terminal connections through its dual functionality.
2Adaptability or versatility
If a separate connector housing with electrical connection terminals is added to provide connection flexibility, then adaptability is improved, but device complexity increases
Solution Approach 1:
The separate connector housing merges multiple functions into a single component: it contains the mating plug connector for engaging with the pump unit's plug connector, houses the electrical connection terminals for alternative terminal connections, and provides a removable cover for safety. This merging of functions into one integrated housing achieves connection flexibility without proportionally increasing overall device complexity.
Solution Approach 2:
The separate connector housing is designed as a universal component that can accommodate multiple connection types. It contains both a mating plug connector for plug-to-plug connections and electrical connection terminals for terminal connections, making it a multi-functional adapter that simplifies the overall system by providing multiple connection options through a single housing structure.
3Ease of operation
If electrical connection terminals are permanently exposed for easy cable connection, then ease of operation is improved, but safety and compliance with electrical standards deteriorate
Solution Approach 1:
The connector housing incorporates a removable cover that dynamically changes the accessibility of the electrical connection terminals. When the cover is removed, terminals are accessible for cable connection; when the cover is in place, terminals are protected and isolated. This dynamic design allows the system to switch between ease of operation (terminals accessible) and safety/compliance (terminals protected), providing both states as needed.

AI summary
A pump unit (2) includes a first housing with at least a first electrical plug connector (12) on the outside of the first housing and a separate connector housing (16) connected to the first housing and including at least a first mating plug connector. The mating plug connector is engaged with the first electrical plug connector (12). An electrical connection terminal (42) is provided in the interior of the separate connector housing (16), which electrical connection terminal (42) is connected to the first mating plug connector and is configured for connection to one electrical cable or a plurality of electrical cables.
