High-Power Charging Plug with Rivet Fastening and Multi-Vehicle Socket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-power charging plugs are inefficient for quick charging of multiple vehicles simultaneously due to complex assembly issues and lack of multi-vehicle charging capability, with existing plugs only allowing single vehicle charging at a time.
Innovation Solution
A high-power charging plug design featuring a case body with a pull ring component, integrated terminal set, and a socket functionality, allowing multiple plugs to be connected for simultaneous charging, with enhanced assembly and durability through rivet sleeves and a protective cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a threaded connection is used to connect the pull ring to the case body, then the assembly can be connected, but the fixation property is poor and there is a high risk of falling off
Solution Approach 1:
The patent extracts the threaded connection structure from the pull ring assembly and replaces it with a rivet-based mechanical fastening system. The pull ring is connected to the case body through rivets that pass through dedicated holes, eliminating the need for threads and providing more reliable fixation without complex assembly steps.
Solution Approach 2:
Instead of using internal threading within the pull ring or case body, the patent inverts the approach by using external rivets that pass through both components. This reverses the traditional fastening method and provides superior mechanical strength and reliability for the pull ring connection.
2Productivity
If a single charging plug structure is used, then the plug can be manufactured simply, but it can only charge one vehicle at a time
Solution Approach 1:
The patent designs the charging plug with multi-functionality, enabling it to charge multiple vehicles simultaneously. The plug body incorporates multiple independent charging outlets that can accommodate different vehicle types, making a single plug structure serve multiple charging functions and increasing overall productivity.
Solution Approach 2:
The charging plug is segmented into multiple independent charging modules within a single plug body. Each module can independently charge a vehicle, allowing the plug to handle multiple vehicles simultaneously while maintaining a unified structure that doesn't require multiple separate plugs.
3Power
If conventional charging plugs are used, then the design is simple, but they cannot meet the demand for quick charging
Solution Approach 1:
The patent merges multiple high-power charging capabilities into a single plug structure. By combining multiple high-current outlets and advanced electrical components within one plug body, the system achieves high-power quick charging for multiple vehicles simultaneously, rather than requiring separate conventional plugs for each vehicle.

AI summary
A high-power charging plug is disclosed. The charging plug comprises a case body having an installation cavity disposed therein, installation holes disposed at both sides thereof, front terminal holes disposed on a front side thereof, and back terminal holes disposed on a back side thereof; a terminal set including a plurality of independent terminals having one-piece front terminals and back terminals, a pull ring component including a pull ring, rivets, and rivet sleeves. The charging plug is not only a plug but also a socket. Another charging plug can be plugged into the socket on the charging plug in use to charge multiple products at the same time. It is convenient and practical.
