The present invention relates to an antenna device, and more particularly to an antenna adapter structure that can be assembled into a large-aperture assembly hole to transfer two different specifications of the line/connector to achieve signal transmission.

The antenna of the wireless communication subsystem is an electronic device that transmits and receives radio waves and electromagnetic waves, and is applied to systems such as broadcasting and television, point-to-point wireless communication, radar, and space exploration. Nowadays, the level of technology and technology has been improved, such as smart meters, water meters, cargo tracking, security monitoring and remote equipment maintenance. At present, the wireless network signal service is mainly based on an outdoor erection base station, so that a large coverage rate effect can be obtained. Therefore, an industrial grade and an outdoor protection level equipment are required, and it is necessary to maintain good signal transmission quality after many years.

According to the specifications of the existing wireless communication case and the internal antenna design, the side wall of the casing is provided with two kinds of common gauge openings, and are respectively connected with the internal antennas, thereby transmitting signals received by the external antenna to the internal antenna. However, the existing open-cell opening design can only be connected with the opening of the smaller aperture, and cannot be connected with the opening of the large aperture, which causes the inner/outer wire to be assembled and the integration of the built-in high-gain antenna is not easy.

In view of this, in order to solve the above-mentioned deficiencies of the prior art, the creator has devoted himself to researching and cooperating with the use of academics, trying to solve the above problems, that is, the goal of the creator's improvement.

One of the purposes of the present invention is to provide an antenna adapter suitable for a connector having a large aperture assembly hole for relaying two different specifications of lines/connectors for signal transmission.

To achieve the above object, the present invention provides an antenna switching device comprising a box body and a adapter. The box body is provided with at least one assembly hole, and the adapter is mounted to the at least one assembly hole. The adapter includes a housing, a first joint, and a second joint. The first joint protrudes out of the housing and protrudes toward the inside of the casing with respect to the assembly hole. The second joint protrudes toward the outside of the casing with respect to the assembly hole, wherein the diameter of the first joint is smaller than the diameter of the second joint.

The creation also has the following advantages: a pressure-resistant glue is provided between the adapter and the flange to prevent the casing from being loosened from the assembly hole due to vibration, temperature change caused by sun and rain, or acid-base corrosion. The T-nut on the adapter is designed to fit the corresponding assembly hole size and includes ridges and cuts to help the user screw the adapter onto the assembly hole.
