Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connections between shielding and housing bodies deteriorate under significant vibration loads, such as those encountered in the automobile field, leading to a loss of electrical conductivity.
Innovation Solution
An electrical connection arrangement with a pressing member that applies a pressing force to maintain a stable connection between the shielding and the housing body, using a deformable sleeve or separate elements that can be repeatedly actuated to ensure a low-resistance, durable electrical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a crimped connection between sleeves and housing body is used, then the assembly is simple to manufacture, but the electrical connection deteriorates under vibration loads
Solution Approach 1:
The pressing member is designed to be movable between a connection position (for assembly) and a pressing position (for secure electrical connection). This dynamic transformation allows the system to transition from an easy-to-assemble state to a high-reliability state, resolving the contradiction between manufacturing simplicity and connection stability under vibration loads.
Solution Approach 2:
The pressing member is pre-configured to apply pressing force to the contact element and shielding before the cable assembly is subjected to vibration loads. This preliminary action ensures that the electrical connection is already secured and resistant to vibration, while still allowing for simple initial assembly.
2Reliability
If a deformable sleeve is used for pressing, then the electrical connection remains stable under vibration, but the device complexity increases
Solution Approach 1:
The pressing member is merged with the housing body in many embodiments, where the housing body itself is designed to perform the pressing function. This integration reduces device complexity while maintaining the reliability benefits of the pressing mechanism under vibration loads.
3Ease of manufacture
If the pressing member is made integral with the housing body, then the structure is simpler to produce, but the ease of assembly and disassembly is reduced
Solution Approach 1:
The pressing member maintains its dynamic capability even when integrated with the housing body, allowing it to move between connection and pressing positions. This enables the system to be both simple to manufacture (integral structure) and easy to assemble/disassemble (movable pressing member).
4Ease of operation
If the shielding is freely movable during insertion, then the ease of operation is improved, but the electrical connection stability is compromised
Solution Approach 1:
The pressing member dynamically transitions from allowing free movement during insertion (connection position) to restricting movement and providing stable electrical connection (pressing position). This resolves the contradiction between ease of operation during assembly and connection stability during operation.
Solution Approach 2:
The pressing member applies preliminary pressing force to secure the shielding and contact element before the cable assembly is subjected to operational stresses. This preliminary action ensures both easy insertion (by allowing movement during assembly) and stable electrical connection (by securing the components before use).
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a permanently good electrical connection with low transition resistance, allowing for mobility and ease of assembly while withstanding vibrations, and ensuring consistent conductivity.
Implementation Method 1
The pressing force created by the pressing member ensures a good electrical connection with a low transition resistance, whereby through the pressing force the shielding or the contact element connected with the shielding is retained.
Implementation Method 2
The sleeve can be permanently deformed for example after insertion of the cable. The sleeve therefore exerts a permanent pressing force directly onto the shielding or onto the contact element that is connected to the shielding.

AI summary
The invention relates to a housing arrangement (1) for attaching at least one cable (4) with a shielding (43) arranged around a conductor (41) as well as an electrical connector (100) comprising at least one such housing arrangement (1) and an electrical connection arrangement comprising an electrical connector. Housing arrangements (1) usually comprise a housing body (2) for receiving a cable end (3). In order to facilitate a permanently good connection between the shielding (43) and the housing body (2), the housing arrangement (1) comprises a pressing member (6) for producing an electrical connection to the shielding (43), wherein, in a pressing position (P), the pressing member (6) is configured to exert a pressing force onto the shielding (43) or onto a contact element (5) that is electrically connected to the shielding (43). The pressing force created by the pressing member (6) ensures a good electrical connection with a low transition resistance, whereby through the pressing force the shielding (43) or the contact element (5) connected with the shielding (43) is retained. The occurring vibrations thus cannot deteriorate the connection to the shielding (43).
