In the first embodiment shown in Figs. 2 and 3, the antenna end connector 230 is shown to be closely fitted to the inner wall of the first end portion 211. In the second and third embodiments shown in FIGS. 4 to 7 , the antenna end connector 230 is mounted on the inner wall of the first end portion 211 of the antenna housing 210 via a plastic holder 240. When the antenna unit 2 is of a larger type and the outer diameter thereof is larger, the plastic holder 240 is filled between the antenna end connector 230 and the inner wall of the first end portion 211 of the antenna housing 210, so that the joint is engaged. The casing 231 is still maintained in the original size to save the amount of metal material of the metal joint casing 231 to reduce the manufacturing cost. The plastic holder 240 and the antenna housing 210 can be fixed in any suitable manner. For example, in the second embodiment shown in FIGS. 4 and 5, the outer wall of the plastic holder 240 is provided with a second glue groove 241. It can be filled with a glue and adhered to the inner wall of the first end portion 211 of the antenna assembly 210. In the third embodiment shown in FIG. 6 and FIG. γ, the outer wall of the plastic seat 240 and the inner wall of the first end portion 211 of the antenna housing 210 are respectively provided with a joint thread 242 and 213, and two phases are provided. Screw-on joint. The antenna waterproof joint device according to an embodiment of the present invention has a simple structure, is convenient to assemble, and most importantly, has a good waterproof effect. As described above, Cui Shi achieves the object of the present invention. While the present invention has been disclosed in the above embodiments, it is not intended to limit the scope of the present invention, and the scope of the present invention can be varied and modified without departing from the spirit and scope of the invention. It is subject to the definition of the scope of the patent application attached.
