Electric Connection Device for Sealed Housing Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to provide a simple, economical, and operationally reliable method for producing electrical connections within a closed housing, particularly for internal electrical devices like traction batteries in electrically operable vehicles, where the connections need to be gas- and/or fluid-tight.
Innovation Solution
An electrical connecting device is integrated into the housing element, featuring external connecting elements, line sections, and connector elements fixedly arranged on the housing, allowing for easy assembly and ensuring connections are made without additional handling, with the connector elements accessible through an assembly opening for secure and efficient connection to supply lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical connections are made inside a closed housing, then gas- and fluid-tight sealing is improved, but assembly complexity increases
Solution Approach 1:
The connector elements are pre-assembled with the housing element in a ready-to-connect state, with connection parts projecting through the assembly opening. This preliminary preparation allows the housing to be closed first, then connections made through the opening, simplifying the overall assembly process while maintaining sealed integrity.
Solution Approach 2:
The assembly opening serves as an intermediary access point that allows connector elements to be accessible from outside while the housing remains closed and sealed. This mediator enables electrical connections to be made without compromising the gas- and fluid-tight sealing of the housing.
2Adaptability or versatility
If multiple separate components are used for electrical connections, then flexibility is improved, but manufacturing cost increases
Solution Approach 1:
The external connecting element, line section, and connector element are merged into a single integrated electrical connecting device that is fixedly arranged on the housing element. This combination reduces the number of separate components, simplifying manufacturing and reducing costs while maintaining connection flexibility through the integrated design.
3Ease of operation
If connector elements are accessible from outside the housing, then ease of connection is improved, but sealing integrity may worsen
Solution Approach 1:
The assembly opening acts as an intermediary that allows connector elements to be accessible from outside the housing for easy connection, while the housing can still be closed to maintain sealing integrity. The opening provides the necessary access without compromising the overall sealed structure.
Solution Approach 2:
The housing element is prepared with pre-assembled connector elements and the assembly opening is positioned and sized in advance. This preliminary action ensures that when the housing is closed, the connectors remain accessible through the pre-planned opening while maintaining sealing integrity around the opening.

AI summary
A reliable contact is produced in a simple and inexpensive manner for an internal electric device surrounded by a housing. An electric connection device for a housing element of the housing has at least one external electric connection element on the housing element for connecting a supply line of the internal electric device to an external electric device outside the housing. At least one line section, electrically connected to the external electric connection element on one side, and at least one terminal element, connected to the line section on the other side, connect to the supply line of the internal electric device. The external electric connection element, the at line section, and the terminal element are fixed on the housing element, and the terminal element is an inner face of the housing element and accessible from an outer face in a vicinity of an assembly opening in the housing element.
