[0037] The connector 5, and the other end of the coaxial cable 4 is connected to the connector 5;

[0038] The connector 5 is provided with an inner conductor, and the inner conductor is connected to the coaxial cable 4;

[0039] In this embodiment, the antenna main body 3 is arranged on the charging pile housing, that is, the antenna main body 3 is located outside the charging pile. The coaxial cable 4 connected to the antenna main body 3 passes through the metal housing and enters the interior of the charging pile. The connector 5 at the other end of the coaxial cable is arranged in the charging pile by using an SMA (SubMiniature version A) interface, so as to achieve the purpose of arranging the antenna main body 3 on the charging pile housing and avoid the problem of poor signal of the built-in antenna in the charging pile;

[0040] If the antenna body 3 is directly exposed outdoors, it is very easy to be damaged. Therefore, an upper case 2 is provided on the charging pile housing, and the antenna main body 3 is arranged below the upper case 2, that is, the upper case 2 can cover the antenna main body 3. In order to facilitate the installation of the upper case 2 and at the same time to isolate the temperature influence brought by the heat conduction of the metal housing of the charging pile, a bottom case 1 is arranged below the upper case 2, and the antenna main body 3 is arranged on the bottom case 1. The upper case 2 can cover the bottom case 1, and the upper case 2 and the bottom case 1 can be fixedly adhered by glue;

[0041] It should be noted that when installing the antenna body 3 on the bottom shell 1, the coaxial cable 4 needs to pass through the charging pile housing and the bottom shell 1 in sequence and then be connected to the antenna body 3.

[0046] Furthermore, in this embodiment, a hole for the perforated bolt 6 to pass through is provided at the center of the bottom shell 1. A through hole extending along the length direction is provided in the middle of the perforated bolt 6, and the coaxial cable 4 passes through this through hole;

[0047] During the process of installing the driving bolt 6 on the bottom shell 1, first pass the perforated bolt 6 through the bottom shell 1, and the direction in which the perforated bolt 6 passes through the hole is away from the upper shell 2, so as to fix the bottom shell 1 on the charging pile housing through the perforated bolt 6 later. Then put the sealing ring 8 on the perforated bolt 6, and the orientation of the sealing ring 8 closely against the bottom shell 1 is away from the upper shell 2. Then install the nut 7 on the perforated bolt 6 to fix the positions of the sealing ring 8 and the perforated bolt 6. A large amount of glue is required during the process of fixing the antenna body 3 on the bottom shell 1, and the sealing ring 8 is used to prevent the glue from leaking out through the gap between the perforated bolt 6 and the bottom shell 1;

[0048] In a preferred embodiment, the process of installing the bottom shell 1, the upper shell 2, and the antenna body 3 on the charging pile housing is as follows: First, pass the perforated bolt 6 through the hole of the bottom shell 1, then put the sealing ring 8 on the driving bolt 6, and then install the nut 7 on the perforated bolt 6 to fix the perforated bolt 6 and the sealing ring 8 on the bottom shell 1.
