Description

Technical Field

[0001] The utility model relates to the field of connector accessories, in particular to a new energy vehicle charging pile connector plug rod. Background Art

[0002] A connector is a device that connects the power system to external equipment. It is used in a variety of fields such as energy storage, new energy vehicles, rail transit, and process control automation equipment. It has the characteristics of high efficiency, stability, safety, and high reliability. In new energy vehicle charging piles, the connector plug is used to conduct electrical energy and is an indispensable part of new energy vehicle charging equipment.

[0003] In the structure of the connector, the plug part is usually fixedly connected to the insulating housing in the connector. If there is a gap between the plug and the insulating housing, it is not only easy to cause power loss during transmission, but also there are certain safety hazards.

[0004] The plug of the connector often has micro-friction wear problems in the working environment, and there is also a small amount of mechanical wear during plugging and unplugging. These wears will greatly reduce the service life of the plug over time. Through electroplating process, the contact surface and connection holes of the plug can be strengthened, the wear resistance can be improved, and the mechanical and electrical properties of the plug and connector can be kept stable for a long time during use. However, during electroplating, the surface of the plug is easily affected, and burrs and uneven plating are prone to occur during electroplating. Utility Model Content

[0007] A new energy vehicle charging pile connector plug rod, the structure of which includes:

[0008] The socket section is used to connect to the power inlet of the new energy equipment;

[0009] A plug head, wherein the bottom surface of the plug head is provided with a mounting hole for connecting with a conductive component;

[0010] A connecting section, connecting the socket section and the plug head, used to connect with the external insulating shell, the connecting section is provided with an annular protrusion for assisting in fixing the external insulating shell and a limiting protrusion for limiting the position of the external insulating shell;

[0011] An electroplating process hole is provided on the side surface of the connecting section, and the electroplating process hole is communicated with the mounting hole.

[0012] The socket section is provided with a connecting hole.

[0022] The structure and embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0023] like Figures 1 to 4 As shown, a new energy vehicle charging pile connector plug rod, the structure of which includes a socket section 1, a connecting section 2 and a plug rod head 3. The socket section 1 is used to connect to the power access port of a new energy device such as an energy storage power supply. In the present utility model, the new energy device specifically refers to a new energy vehicle charging pile. The plug rod head 3 is used to connect to conductive components such as wires, cables, and plugs. The connecting section 2 connects the socket section 1 and the plug rod head 3, and is used to connect to an external insulating shell.

[0024] The bottom surface of the plug head 3 is provided with a mounting hole 31, and the mounting hole 31 is used to connect with a conductive component such as a connector and a wire. The mounting hole 31 is a cylindrical cavity, and the mounting hole 31 is set through the connecting section 2.

[0025] The connecting section 2 is provided with an annular protrusion 22 for auxiliary fixing, and the annular protrusion 22 is adapted to the annular groove provided in the external insulating shell. During installation, the annular protrusion 22 is embedded in the annular groove of the external insulating shell, so that the connection between the plug rod and the external insulating shell is tighter.

[0026] In order to prevent the external insulating shell from sliding up and down when fixed on the connecting section 2, a limiting protrusion 23 is also provided on the connecting section 2. The limiting protrusion 23 is chamfered to reduce the wear of the connection between the connecting section 2 and the external insulating shell, ensuring a smooth connection between the plug rod and the external insulating shell.

[0027] The side of the connecting section 2 is provided with an electroplating process hole 21, which is connected to the mounting hole 31. In the electroplating process, the electroplating process hole 21 is set on the fixed hook, and the surface of the plug rod can be electroplated more stably, reducing the impact on the surface of the plug rod. After the electroplating is completed, the plating layer on the plug rod is more uniform and has fewer burrs than when it is not stably set, and the overall electroplating quality is higher.

[0028] The socket section 1 is provided with a connection hole 11, and the connection hole 11 is used to connect the bus with the guide line in the power inlet of the new energy equipment.

[0029] In order to make the connection structure more stable, threads for connection and fixing are provided inside the mounting hole 31 and the connection hole 11 .

[0030] In order to achieve excellent conductive performance, the socket section, the plug rod head and the connecting section in the utility model are integrally formed and are all made of brass.

[0031] The above content describes the structure, main embodiments and advantages of the utility model. It should be noted that the specific implementation of the utility model is not limited to the above-mentioned methods. As long as various non-substantial improvements are made by adopting the technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model. The protection scope required by the utility model is defined by the attached claims and their equivalents.
