Common Locking Plate for High-Voltage Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current high-voltage network distribution devices in motor vehicles require cumbersome and time-consuming assembly processes due to the need for separate locking mechanisms for each connection, which complicates the connection and disconnection of high-voltage contacts, increasing the risk of accidental disconnection and reducing safety.
Innovation Solution
A large-area locking plate that engages simultaneously with all connectors, allowing for a single operation to interlock multiple high-voltage contacts, combined with a second locking plate on a pilot line connection that ensures the high-voltage network is de-energized before assembly, enhancing safety by preventing accidental contact disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate locking devices are used for each connection, then each connector can be individually secured, but the assembly process becomes time-consuming and labor-intensive
Solution Approach 1:
Multiple separate locking devices are merged into a single common locking plate that serves all connections simultaneously. The locking plate contains multiple locking elements that can engage with multiple connectors at once, transforming individual locking operations into a single unified operation, thereby dramatically improving assembly speed while maintaining connector security.
Solution Approach 2:
The common locking plate is designed as a universal component that can lock multiple different connectors across multiple connections simultaneously. This multi-functional design allows one locking device to perform the function of several separate locking devices, reducing the number of operations required during assembly while ensuring each connector is properly secured.
2Reliability
If separate locking devices are used for each connection, then each connector can be individually locked, but the system complexity increases
Solution Approach 1:
Multiple independent locking devices are combined into a single integrated common locking plate structure. This merging reduces the total number of separate components in the system while maintaining the individual locking capability for each connector, thereby simplifying the overall system complexity without compromising security.
Solution Approach 2:
The common locking plate serves as a universal locking mechanism for all connections, replacing multiple specialized locking devices. This multi-functional approach reduces the variety of different components needed in the system, making the locking system less complex and easier to manufacture and maintain.
3Ease of operation
If connectors can be individually removed, then maintenance is flexible, but the risk of accidental disconnection increases
Solution Approach 1:
The common locking plate requires a single unified action to lock or unlock all connectors simultaneously, preventing accidental individual disconnections. This merged locking mechanism ensures that if one connector needs to be accessed, all connectors must be unlocked together through a deliberate single operation, significantly reducing the risk of accidental disconnection while maintaining maintenance flexibility.

Function Achieved in This Case
This solution significantly reduces assembly time and enhances safety by allowing simultaneous locking of multiple high-voltage contacts and ensuring that the high-voltage network is de-energized during maintenance, preventing accidental reconnection.
Implementation Method 1
The first locking plate is spring-loaded in the region of the groove, wherein the spring is biased when crossing the step outside the positions

AI summary
A current distribution device for a high-voltage network, in particular in a motor vehicle, includes at least two first connections that can be locked in such a way that, after a locking device is closed, a connector plugged into the connection can no longer be removed, wherein the first connections have a first locking plate as a common locking device.
