Vehicle Battery Charger Grounding Connector With Cable Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery chargers for electric or hybrid motor vehicles require manual retention of the grounding cable during installation, which can lead to damage and increased installation time due to cable movement during screwing, and existing solutions do not adequately address these issues.
Innovation Solution
The battery charger incorporates retaining means with elastic locking elements that securely hold the grounding cable in place without manual retention, using a connector with elongated bodies and elastic locking mechanisms to prevent movement and damage, allowing for easy installation and replacement of retaining components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw and nut connection is used to fix the electrical terminal to the connecting element, then the electrical grounding cable can be mechanically fixed, but the cable is free to move during screwing due to friction, requiring manual retention and increasing installation time
Solution Approach 1:
The patent applies preliminary action by pre-positioning the electrical grounding cable in a dedicated cable receiving area with retaining means before the screwing operation begins. The retaining means, including elastic locking elements and positioning structures, are already in place to prevent cable movement during the connection process, eliminating the need for manual retention and reducing installation time while ensuring reliable connection.
2Reliability
If a screw and nut connection is used to fix the electrical terminal to the connecting element, then the cable can be mechanically fixed, but the cable may be unintentionally moved and damaged during screwing
Solution Approach 1:
The patent applies preliminary anti-action by implementing retaining means with elastic locking elements and positioning structures that counteract the harmful movement of the cable before it can occur during screwing. The elastic locking elements engage with the cable in advance, creating a protective mechanism that prevents the cable from being unintentionally moved or damaged during the connection process, thereby eliminating the need for manual retention.
3Object-affected harmful factors
If the container body is made of metal material to provide resistance and electromagnetic shielding, then the electronic appliance is protected from electromagnetic interference, but the container body must be electrically connected to ground potential by a grounding cable
Solution Approach 1:
The patent applies merging by integrating the grounding connector and cable management functions into a single unified component structure. The grounding connector includes both the electrical connection elements (screw, nut, terminal) and the cable retaining means (elastic locking elements, positioning structures) as an integrated assembly, simplifying the overall grounding connection system while maintaining electromagnetic shielding protection.
