Description

Technical Field

[0001] This utility model relates to the field of Beidou positioning antenna technology, and more specifically, to an external waterproof Beidou positioning antenna. Background Technology

[0002] Beidou positioning antennas are used to receive signals emitted by Beidou satellites. These signals carry the information required for positioning and navigation and propagate in the form of electromagnetic waves. The antenna converts these electromagnetic wave signals into high-frequency currents and processes the signals through amplifiers to improve the signal strength and signal-to-noise ratio, thereby enhancing the receiving distance and positioning accuracy. In terms of placement, Beidou antennas are divided into built-in antennas and external antennas.

[0003] Existing external BeiDou positioning antennas have poor waterproof performance, allowing rainwater to easily enter the antenna body when used outdoors. This increases the risk of short circuits and corrosion of electronic components on the PCB board, making it difficult to meet the usage needs of end users in different environments and affecting the service life of the BeiDou positioning antenna. Based on this, this utility model designs an external waterproof BeiDou positioning antenna to solve the above problems. Utility Model Content

The BeiDou ceramic antenna is soldered to the upper end of the PCB board. A waterproof rubber ring is fixedly installed on the plastic lower shell outside the shielding cover. The PCB board is snapped into the plastic upper shell, and the bottom edge of the PCB board abuts against the top of the waterproof rubber ring. An RG174RG RF cable is soldered onto the PCB board, and the front part of the waterproof rubber ring is fitted over the RG174RG RF cable. The plastic upper shell and the plastic lower shell are connected by screws.

[0007] As a preferred embodiment of this utility model, the RG174RG RF cable passes through the side of the upper and lower plastic shells, and one end of the RG174RG RF cable is provided with an SMA connector.

[0011] As a preferred embodiment of this utility model, the number of screws is four, and the screws are distributed at each corner of the plastic lower shell.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention improves the waterproof performance of the Beidou positioning antenna by installing a shielding cover on the lower plastic shell, with electronic components extending inside the shielding cover to block external electromagnetic interference. The Beidou ceramic antenna is soldered to the upper end of the PCB board. A waterproof rubber ring is installed on the lower plastic shell outside the shielding cover. The PCB board is clipped into the upper plastic shell, with the bottom edge of the PCB board abutting against the top of the waterproof rubber ring. The front part of the waterproof rubber ring is fitted over the RG174 RF cable, thereby effectively improving the waterproof performance of the Beidou positioning antenna to an IP67 waterproof rating. This prevents rainwater from entering the antenna body when used outdoors, reduces the risk of short circuits and corrosion of electronic components on the PCB board, and helps ensure the service life of the Beidou positioning antenna.
