Abstract
The utility model is applicable to the technical field of antennas, and discloses a small outdoor waterproof antenna. The small outdoor waterproof antenna comprises an antenna upper cover and an antenna lower cover; an antenna metal assembly is arranged between the antenna upper cover and the antenna lower cover, wherein the antenna metal assembly is electrically connected with one end of a coaxial wire, and the other end of the coaxial wire is connected with an antenna receiving/transmitting circuit; the edge of the antenna lower cover is provided with a circular groove, and the circular groove is hermetically matched with a step structure arranged on the end face of the antenna upper cover. As the edge of the antenna lower cover is provided with the circular groove matched with the step structure of the antenna upper cover, the step structure and the circular groove are enabled to be tightly contacted through ultrasonic welding in assembly, so that the antenna upper cover and the antenna lower cover are enabled to form a sealed space. When the antenna with such a structure is placed in the outdoor, rainwater can not come into the inner part through the antenna upper cover and the antenna lower cover, thereby avoiding poor contact caused by oxidation of the metal assembly of the antenna, and improving the stability and the reliability of the outdoor antenna.

Embodiment
In order to make purpose, technical scheme and the advantage of wanting utility model clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work belongs to the scope that the utility model is protected.
As depicted in figs. 1 and 2, the utility model provides a kind of small outdoor waterproof antenna embodiment.
This small outdoor waterproof antenna comprises: antenna upper casing 1 and antenna lower casing 2, at antenna upper casing 1 and the antenna lower casing 2 middle antenna metal assemblies 5 that are provided with, this antenna metal assembly 5 is electrically connected with concentric conductor 4 one ends, these concentric conductor 4 other ends are connected with antenna reception or radiating circuit, wherein said antenna lower casing 2 edges are provided with cannelure 21,11 airtight cooperations of ledge structure that this cannelure 21 and antenna upper casing 1 end face arrange.
When assembling, described antenna lower casing 2 edges are provided with the cannelure 21 that cooperates with the ledge structure 11 of antenna upper casing 1, pass through ultra-sonic welded, make ledge structure and cannelure close contact, make antenna upper casing and antenna lower casing form an airtight space, when the antenna of this structure placed the open air, rainwater can't enter inside from antenna upper casing and antenna lower casing, the loose contact of avoiding the metal assembly generation oxidation because of antenna to cause improves stability and the reliability of open antenna.
