[0002] An electric vehicle (EV) charging socket is an interface and device used to provide electrical power to an electric vehicle. The type and specifications of charging sockets vary depending on different standards and requirements.

[0003] Traditional electric vehicle charging sockets require the wire harness crimped to pass through the tail cap and an integrated sealing ring. Due to the anti-sway structure of the tail cap and the sealing ring, as well as the interference fit of the product itself, assembly is very difficult, especially after the power wire is inserted, where the assembly resistance is extremely high, making manual operation time-consuming and labor-intensive. Furthermore, the size of the wire harness pulled in needs to be strictly controlled during the wire harness pulling process, and repeated operations on the sealing ring will affect the product's sealing performance. Relying on manual crimping and assembly makes it difficult to achieve automated mechanical production, resulting in unsatisfactory production efficiency and costs. Utility Model Content

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] As attached Figure 1 and attached Figure 2 As shown:

[0024] Example 1: This example provides an integrated cable outlet structure for a DC charging socket, including a PCB board 1, probes 2, charging connectors 3, a charging communication negative signal line 4, a charging connection confirmation signal line 1 5, a charging communication positive signal line 6, a low-voltage auxiliary power positive signal line 7, a low-voltage auxiliary power negative signal line 8, multiple plugs 9, and a second charging connection confirmation signal line 10. Probes 2 are located on the front surface of the PCB board 1 and are electrically connected to the charging connector 3. The multiple plugs 9 are all located on the rear surface of the PCB board 1 and are electrically connected to the charging communication negative signal line 4, the charging connection confirmation signal line 1 5, the charging communication positive signal line 6, the low-voltage auxiliary power positive signal line 7, the low-voltage auxiliary power negative signal line 8, and the second charging connection confirmation signal line 10, respectively.

[0025] This application integrates the originally scattered signal lines into a standardized connector PCB board 1, and achieves modular connection through the PCB board 1, replacing the traditional manual wire crimping process;

[0026] In this application, PCB board 1 serves as the core carrier, integrating signal transmission paths and physical support structures. Probe 2 is a metal conductive contact used to transmit current signals. Charging connector 3 serves as the interface for inserting an external charging gun. The positions of the charging communication negative signal line 4, charging connection confirmation signal line 1 5, charging communication positive signal line 6, low-voltage auxiliary power positive signal line 7, low-voltage auxiliary power negative signal line 8, and charging connection confirmation signal line 2 10 are set according to the standard settings of traditional electric vehicle charging sockets. The position of plug 9 corresponds to it for precise docking.

[0027] The probe 2 is directly soldered to the front end of the PCB board 1 and precisely interlocks with the pin slot 303 of the charging connector 3, eliminating the traditional step of threading the wire harness through the sealing ring.

[0028] The charging connector 3 adopts a split structure: the front connector 301 is plugged into the outside, and the rear pin groove 303 is fixedly connected to the PCB board.

[0029] All signal lines are integrated to the rear end of PCB board 1 via plug 9 to form a standard connector interface. PCB board 1 acts as a rigid carrier and achieves permanent sealing with the housing through a single fixing, avoiding repeated wire threading that could damage the sealing ring.

[0030] Specifically, the rear end of the charging connector 3 is provided with a pin groove 303, which is adapted to the probe 2, and the front end of the charging connector 3 is provided with a connection port 301.

[0031] The charging connector 3 is connected to the probe 2 via the pin groove 303 and to an external charging gun via the connector 301. A sleeve is provided on the PCB board 1 surrounding the probe 2 to lock the probe 2 onto the charging connector 3 when it is connected to the pin groove 303.

[0032] Specifically, PCB board 1 has openings 102 on both sides, and through holes 101 are provided on PCB board 1 between the openings 102. The openings 102 are the standard positions of the DC power negative and DC power positive lines of a traditional charging socket, and the through holes 101 are the standard positions of the protective grounding of a traditional charging socket. This allows it to be compatible with traditional charging sockets and reduce production costs.

[0033] As can be seen from the above, the signal transmission path is: charging connector 3 → probe 2 → PCB board 1 wiring → plug 9 → signal line → charging gun.

[0034] As attached Figure 3 and attached Figure 4 As shown:

[0035] Example 2: This example is basically the same as the previous example, except that a housing 11 is provided around the charging communication negative signal line 4, the charging connection confirmation signal line 1 5, the charging communication positive signal line 6, the low-voltage auxiliary power positive signal line 7, the low-voltage auxiliary power negative signal line 8 and the charging connection confirmation signal line 2 10. A threaded hole 104 is provided on the housing 11, and the PCB board 1 is threadedly connected to the threaded hole 104 by bolts 103.

[0036] Specifically, a front cover 12 is fastened to the front end of the outer shell 11 of the PCB board 1. A through groove 305 is provided on the front cover 12, which is adapted to the charging connector 3.

[0037] Specifically, the charging connector 3 is provided with a flexible buckle 302, and the front cover 12 is provided with a card holder 304, which is compatible with the flexible buckle 302.

[0038] As can be seen from the above, after connecting the plug 9 of PCB board 1 to each signal line, the bolt 103 is threaded through the threaded hole 104 on the charging socket housing 11 to fix PCB board 1. Then, the front cover 12 is fastened on the housing 11 to protect PCB board 1. The charging connector 3 passes through the through groove 305 and is connected to PCB board 1 through the front cover 12. During the process, the elastic buckle 302 is pushed to make it engage with the card seat 304 to fix the position of the charging connector 3.
