Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional charging sockets in electric vehicles are difficult to assemble, have poor heat dissipation, and require labor-intensive replacement, posing safety risks during maintenance and replacement due to potential short circuits.
Innovation Solution
A replaceable charging socket design featuring a charging socket body, transition flat cable, and conductive cable, allowing the socket body to be detached by separating the transition flat cable from the conductive cable, eliminating the need to detach the conductive cable from the vehicle body during replacement or maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the terminal and conductive cable are connected by crimping or welding and integrally assembled on the main shell, then the charging socket structure is complete, but the assembly is difficult and heat dissipation performance is poor
Solution Approach 1:
The charging socket is divided into modular components: the main shell with charging terminal, the transition flat cable, and the conductive cable. These segments can be assembled separately with better heat dissipation and easier manufacturing, then connected through detachable interfaces rather than integral welding or crimping.
Solution Approach 2:
The transition flat cable serves as an intermediary component between the charging terminal and the conductive cable. This intermediary structure improves heat dissipation by separating the connection points and facilitates easier assembly by providing a flexible connection interface that eliminates the need for complex crimping or welding operations.
2Stability of the object's composition
If the charging socket is fixedly mounted on the vehicle body, then the charging system is stable, but replacement is time-consuming and labor-intensive
Solution Approach 1:
The charging socket system is segmented into the vehicle-mounted main shell and the detachable charging terminal assembly. This allows the main shell to remain stably mounted on the vehicle body while the terminal assembly can be quickly replaced by simply detaching the transition flat cable from the conductive cable, eliminating the need to detach the entire fixed mounting structure.
Solution Approach 2:
The charging socket design incorporates dynamic detachability: the main shell maintains a fixed, stable connection to the vehicle body, while the terminal assembly features a dynamic, easily detachable connection through the transition flat cable interface. This enables rapid replacement without compromising the stability of the mounted structure.
3Reliability
If the charging socket is fixedly mounted, then the connection is secure, but maintenance personnel are at risk of electric shock during maintenance
Solution Approach 1:
The charging terminal and transition flat cable can be extracted from the vehicle-mounted main shell as a separate detachable assembly. This allows maintenance personnel to remove the electrified components before performing maintenance on the main shell, eliminating the risk of electric shock while maintaining secure connection during normal operation through the detachable interface.

AI summary
The present disclosure discloses a conveniently replaceable charging socket and a vehicle, which relates to the technical field of new energy vehicle manufacturing and includes a charging socket body (1), a transition flat cable (2) and a conductive cable (3). The charging socket body (1) is provided therein with a charging terminal (11). The transition flat cable (2) has one end connected to the charging terminal (11), and the other end detachably connected to the conductive cable (3). The present disclosure has the advantageous effects that when the charging socket is to be replaced, the charging socket body can be detached from the vehicle body just by separating the transition flat cable from the conductive cable, and the conductive cable that has been fixed in the vehicle body is not required to be detached. In addition, the present disclosure can disconnect an electrified system during maintenance of the charging socket or before charging, thereby eliminating the risk of electric shock to maintenance personnel.
