Hinged Cover Electrical Connector Cable Strain Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors in motor vehicles fail to effectively prevent cable stresses and vibrations from being transferred to the connection between the cable and contact, leading to increased costs due to the need for separate cable securing devices.
Innovation Solution
A hinged cover connected to the connector housing with guide slots that constricts the cable when closed, providing a secure fixation without additional parts, allowing for easy assembly and strain relief.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate cable securing device is used to prevent cable stresses from being transferred to the connection, then cable fixation reliability is improved, but device complexity and assembly costs increase
Solution Approach 1:
The patent integrates the cable securing function directly into the connector housing structure. The housing includes integrated cable securing elements such as recesses, grooves, or clamping surfaces that directly secure the cable without requiring separate securing devices. This merging of functions reduces part count and assembly complexity while maintaining reliable cable fixation.
Solution Approach 2:
The connector housing is designed to perform multiple functions: electrical connection, mechanical locking, and cable securing. The housing structure incorporates features that simultaneously provide structural support, contact retention, and cable fixation, making the connector a multi-functional component that eliminates the need for additional dedicated cable securing parts.

AI summary
An electrical connector is provided with a hinged cover, which is connected in one piece to a connector housing. At least one guide slot is formed in a cover portion of the cover and opens outwards towards a free end of the cover portion. A cable is positioned in the guide slot upon closing the cover, and the guide slot is constricted when the cover is closed so that the cable is fixed inside it. The result is a secure fixing of the cable with low cost in terms of parts and assembly.
