At the same time of locking, the waterproof bezel 300 is tightly pressed to be in close contact with the outer side wall 43 of the casing 4 and the first end portion 111 of the antenna unit 1 so that external rain or liquid does not intrude into the machine. The inside of the case 400 and the antenna unit 1〇〇, and the intrusion into any joint portion, achieves a completely waterproof function. The plug-in antenna waterproof joint device according to the first embodiment of the present invention eliminates the arrangement and assembly of the device end connector and the antenna end connector, so that the structure is simple, the assembly is convenient, and most importantly, the waterproof effect is good. . As described above, the object of the present invention has indeed been achieved. The plug-in connector 130 can be mounted to the interior of the first end portion 111 of the antenna housing 110 in any suitable manner. In the first embodiment shown in Figs. 2 and 3, the plug-in type joint 13 is shown to be fitted to the inner wall of the first end portion 111 with its assembly portion 131. In the second and third embodiments shown in FIGS. 4 to 7, the assembly portion 131 of the plug-in connector 130 is mounted on the first end of the antenna housing 11 via a plastic holder 150. The inner wall of the portion hi, when the antenna unit 200 is of a larger type and has a larger outer diameter, is filled with plastic between the plug-in joint 130 and the inner wall of the first end portion ill of the antenna housing 11 The seat 150' allows the plug-in connector to remain in the original size to save the metal material of the metal plug-in connector 130 to reduce manufacturing costs. The plastic seat 150 and the antenna housing 110 can be fixed in any suitable manner. 201248989 is fixed. For example, in the second embodiment shown in FIG. 4 and FIG. 5, it is shown that the outer wall of the plastic seat 150 is provided with two plastic grooves. 151, which can be glued and adhered to the inner wall of the first end portion 111 of the antenna housing 110. In the third embodiment shown in FIGS. 6 and 7 , the outer wall of the plastic seat 15 与 and the inner wall of the first end portion 111 of the antenna housing 110 are respectively provided with a joint thread 152 and 113 ′ and two Phase screw joint. In addition, in the assembly of the assembly portion 131 of the plug-in fitting 130 and the plastic seat 150, the plastic seat 15 includes a body 153 having an inner shoulder 154 at the center thereof. The inner circumference 155 and the outer circumference of the 154 respectively form a small diameter inner hole 155 and a large diameter assembly groove 156, and the inner shoulder portion 154 is provided with a protruding ring 158 in the direction toward the assembly groove 156. The assembly portion 131 of the plug-in connector 130 has an outer shoulder portion 135. The inner circumference and the outer periphery respectively form a small-diameter through-hole 136 and a large-diameter assembly 137. The through-body 136 is disposed through The inner hole 155 of the plastic seat 150 and the assembly body 137 are received in the assembly groove 156 of the plastic seat 150, and the outer shoulder portion 135 is abutted against the protruding ring 158 of the shoulder portion 154 of the plastic seat 15 . According to the abutted ring 158, the plastic seat 15 〇 and the plug-in joint 130 have a good waterproof effect. The plug-in type antenna waterproof jointing apparatus according to the second and third embodiments of the present invention also has the same functions as those of the first embodiment, such as simple structure, convenient assembly, and good waterproof effect. 8 and 9 are respectively a cross-sectional view and a partial enlarged view of a plug-in type antenna waterproofing device in accordance with a fourth embodiment of the present invention. In the fourth embodiment, the plug-in type waterproof joint device further includes a metal plate body 160 which is sleeved on the outer periphery of the body 136 of the plug-in joint 13〇, and 201248989 • (4) water 塾 _G and (4) Between the seats (10), and the plug-type connector coffee and the outer wire metal wire 142 of the coaxial wire 140 and the ground end of the antenna body 12〇 are electrically connected, and the coaxial wire 14 is improved according to the metal plate body 160 provided. The grounding effect of the antenna body 12〇. In addition, the inner shoulder portion 154 of the plastic seat 150 is further provided with a groove 157 in the direction of the waterproof gasket 3 ,, and the inner shoulder portion 154 forms an elastic lining 159 between the groove 157 and the inner hole 155, which is closely connected. The penetration of the plug-in connector further provides a good waterproofing effect between the plastic seat and the plug-in joint. The plug-in type antenna waterproof jointing apparatus according to the fourth embodiment of the present invention has the same functions as those of the first embodiment, such as simple structure, convenient assembly, and good waterproof effect, in addition to enhancing the grounding effect.
