Charging Socket Terminal Assembly for Front-Access Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing charging sockets for new energy vehicles require extensive disassembly and replacement of the entire charging terminal and cable when the charging terminal is damaged, leading to inefficient and costly maintenance due to the fixed connection methods like crimping or welding, which complicates the repair process.
Innovation Solution
A charging socket design featuring a detachable device connected to the charging terminal via a connection structure, allowing for easy replacement of the charging terminal without detaching the entire socket or cable, utilizing methods such as welding, crimping, or threaded connections, and incorporating a temperature sensor for real-time monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the charging terminal is fixedly connected to the cable through crimping or welding, then the electrical connection is reliable, but the replacement of damaged charging terminal becomes complex and time-consuming
Solution Approach 1:
The charging terminal assembly is segmented into modular components: the charging terminal itself, the detachable device (connection structure), and the flat cable. This segmentation allows the charging terminal to be replaced independently without affecting the cable or socket body, resolving the contradiction between reliable connection and ease of repair.
Solution Approach 2:
The connection structure transitions from a fixed permanent connection (crimping/welding) to a dynamic detachable connection. The detachable device enables the charging terminal to be easily attached and detached, providing both reliable electrical connection during use and ease of replacement when damaged.
2Stability of the object's composition
If the charging terminal is permanently fixed in the charging socket, then the connection stability is high, but the maintenance efficiency decreases due to extensive disassembly requirements
Solution Approach 1:
The charging socket system is divided into replaceable modules: the charging terminal with its detachable device can be independently removed from the socket body. This segmentation maintains stable connection during operation while enabling quick maintenance by simply detaching the damaged terminal without disassembling the entire socket.
Solution Approach 2:
The design enables easy discarding of damaged charging terminals and recovery/reuse of the socket body and cable assembly. The detachable device allows the terminal to be quickly removed and replaced, while the stable socket structure and cable remain in place for continued use.
3Manufacturing precision
If the cable length is set without repair allowance, then the cable fits precisely in the design, but cable replacement becomes necessary when the charging terminal is damaged
Solution Approach 1:
The electrical connection system is segmented so that the cable remains permanently fixed in the socket body while the charging terminal becomes the replaceable component. This segmentation maintains precise cable length design while eliminating the need for cable replacement, as only the terminal needs to be changed.
Solution Approach 2:
The charging terminal is extracted as a separate replaceable component from the cable assembly. The detachable device allows the terminal to be removed and replaced independently, leaving the precisely fitted cable and socket body intact, thus maintaining manufacturing precision while improving repair ease.

AI summary
The present disclosure provides a charging socket and a vehicle, including: a charging socket body, a charging terminal, a detachable device and a flat cable, in which the detachable device is electrically connected to a conductor of the cable, and is fixedly mounted on the charging socket body; the charging terminal is provided with a connection structure, and is detachably connected to the detachable device by means of the connection structure. In the charging socket, when the charging terminal is damaged or the charging terminal makes poor contact with the cable, it is only necessary to detach the charging terminal from the front, detach an electrical connection device and the cable from the charging socket, replace the electrical connection device and then mount them again, and there is no need to detach the entire charging socket or to replace the cable, thereby solving the technical problem that maintenance work is relatively complicated when the electrical connection device of the charging socket is damaged.
