Plug Connector Grounding via Holding Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modular plug connectors require a separate connection to ground for the plug connector or holding frame, which is inconvenient and involves additional wiring.
Innovation Solution
An electrical plug connector module with an electrically conductive contact element that connects directly to the plug connector housing or holding frame, allowing for a simple ground connection without additional intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate ground connection is provided for the plug connector or holding frame using additional wiring, then the grounding connection is established, but the device complexity and wiring requirements increase
Solution Approach 1:
The patent combines the grounding function with the housing structure by making the housing itself electrically conductive. The housing serves dual purposes: providing mechanical protection and establishing the ground connection, thereby eliminating the need for separate grounding wires and reducing overall wiring complexity.
Solution Approach 2:
The housing is designed to perform multiple functions simultaneously: it provides structural support, electrical insulation for signal contacts, and a ground connection path. By making the housing electrically conductive, it becomes a multi-functional component that eliminates the need for dedicated grounding elements.
2Reliability
If additional separate grounding wiring is provided, then the ground connection is ensured, but the manufacturing process and assembly steps increase
Solution Approach 1:
The grounding function is merged into the housing structure itself. The housing is designed with electrical contact surfaces that directly establish the ground connection when the connector is assembled, eliminating the need for separate grounding wires and simplifying both manufacturing and assembly processes.
Solution Approach 2:
The housing automatically provides the ground connection through its own structure and material properties. The conductive housing serves itself as the grounding path, eliminating the need for additional components or complex assembly steps to establish the ground connection.

AI summary
An electrical plug connector module and holding frame assembly is provided alone or in combination with further plug connector modules for forming a modular plug connector. The electrical plug connector module is inserted directly in the plug connector housing or can be received fastened in the holding frame with further modules in a plug connector housing. The electrical plug connector module includes an electrical contact that is connected in an electrically conductive manner in the interior of the electrical plug connector module to an electrical contact that is received therein. The electrical contact is guided on the outer side of the electrical plug connector module contacts in addition by way of a resilient region the holding frame or the plug connector housing in which the electrical plug connector module is inserted.
