Technical Field
[0001] This utility model relates to the field of electric vehicle electrical connection technology, specifically, a new type of modular European standard car charging socket. Background Technology
[0002] With the rapid development of the global electric vehicle industry, charging infrastructure, as a core supporting equipment, has become a key focus of technological research and development in terms of standardization, safety, and compatibility. Europe, as a region with a high rate of electric vehicle adoption, has widely adopted charging interface standards (such as IEC 62196) in the design of on-board charging sockets. However, existing European standard charging sockets mostly adopt an integrated structure, with AC and DC charging components, electronic locks, and temperature monitoring modules highly integrated, leading to the following problems:
[0003] High upgrade and maintenance costs: When charging standards are updated (such as power increases or communication protocol iterations) or local components (such as electronic locks or temperature sensors) are damaged, the entire socket needs to be replaced, resulting in material waste and financial burden on users.
[0004] Insufficient flexibility: Existing designs are difficult to adapt to new charging technologies in the future (such as ultra-high voltage fast charging), resulting in short product life cycles and increased investment in repeated research and development.
[0005] Limitations of temperature monitoring: Traditional temperature sensor fixing methods have low thermal conductivity, and the tail wire arrangement can easily lead to a bulky tail cap structure, which poses a risk of falling off and affects the reliability of safety monitoring.
[0006] Functionality expansion is difficult: the integrated structure makes it difficult to integrate new functional modules (such as status indicator strips), limiting the space for user experience optimization.
[0007] To address the aforementioned issues, the industry has attempted to optimize the structure through a modular design, but shortcomings remain, including poor compatibility between modules, complex assembly and disassembly, and reduced protective performance. Therefore, there is an urgent need for a highly modular and flexibly configurable charging socket design that ensures safety and standardization while enabling low-cost upgrades and functional expansion. Utility Model Content
[0008] To address the aforementioned technical problems, the purpose of this utility model is to provide a novel modular European standard car charging socket, which allows for the replacement or upgrading of specific modules according to customer needs, thereby improving flexibility and practicality, reducing material waste, facilitating future adaptation to new charging standards or upgrades to new functions, extending the lifespan of the charging socket, and saving research and development costs.

One end of the terminal assembly is limited and set inside the housing, and the other end is installed inside the fixing assembly and connected to one end of the wire harness. The other end of the wire harness passes through the sealing body and the tail cover.
[0014] As a further improvement, a bushing is provided inside the housing to limit one end of the terminal assembly.
[0015] As a further improvement, the fastener assembly includes: thermally conductive silicone, a temperature sensor, and a fastener, wherein the thermally conductive silicone is disposed on the fastener and is in contact with the temperature sensor and terminal assembly disposed on the fastener.
[0016] As a further improvement, the fixing component of the DC socket assembly also includes a temperature sensor sealing body, and the housing and tail cover of the DC socket assembly are provided with matching reserved holes. The tail wire of the temperature sensor of the DC socket assembly passes through the reserved holes of the housing and tail cover of the DC socket assembly, and the temperature sensor sealing body is provided at the reserved hole of the housing.
[0017] As a further improvement, the tail cover of the DC socket assembly includes: a large DC tail cover and a small DC tail cover that are fixed to each other, with a reserved hole on the large DC tail cover, and the large DC tail cover is connected to the housing.
[0018] As a further improvement, a shielding ring is provided at the other end of the wire harness, and the shielding ring is located at the front end of the sealing body.
[0019] As a further improvement, a DC tail cover sealing body is provided inside the DC tail cover.
[0020] As a further improvement, the temperature sensor tail wire of the AC socket assembly is arranged to pass through the fixing member, sealing body and tail cover of the AC socket assembly in sequence.

[0022] As a further improvement, the electronic lock is attached to the outside of the AC socket assembly.
[0023] Compared with the prior art, this utility model has the following advantages and beneficial effects:
[0024] (1) This utility model uses four modular components: socket flange, AC socket assembly, DC socket assembly, and electronic lock to realize flexible interchangeability of charging sockets, reduce material waste, facilitate future adaptation to new charging standards or upgrade of new functions, extend the service life of charging sockets, and save R&D costs.
[0025] (2) The temperature sensor tail wire of the DC socket assembly of this utility model passes through the reserved holes in its housing and tail cover. The function of the temperature sensor is to feed back the temperature to the vehicle system to prevent overheating from causing safety hazards. Therefore, the sensor wire passes through the housing, tail cover and sealing body and then connects to the vehicle, which can prevent the tail cover from being too long due to the temperature sensor tail wire, which could cause the tail cover to fall off easily.

In this embodiment, the light strip assembly 2 is disposed outside the cavity accommodating the AC socket assembly 3 and the DC socket assembly 4, and is fixed by screw clips or hot-riveting screws, so that the installation and removal of the light strip assembly 2 does not affect the installation and removal of the AC socket assembly 3 and the DC socket assembly 4.
