[0006] Preferably, in the above-mentioned quick-plug UHF soft whip omnidirectional antenna, the outer wall of the matching device housing is provided with at least one annular groove, and the inner wall of the rubber ring is provided with an annular protrusion matching the annular groove.

[0007] Preferably, in the above-mentioned quick-plug UHF soft whip omnidirectional antenna, a rubber plate is provided on the rubber ring at the end portion of the matcher housing.

[0008] Preferably, in the above-mentioned quick-plug UHF soft whip omnidirectional antenna, the outer diameter of the annular rib is 0.1-0.3 mm larger than the inner diameter of the hollow cavity.

[0009] Preferably, in the above-mentioned quick-plug UHF soft whip omnidirectional antenna, the rubber ring, the annular rib, the annular protrusion and the rubber plate are integrally formed.

[0010] Preferably, in the above-mentioned quick-plug UHF soft whip omnidirectional antenna, the outer diameter of the annular rib is 0.2 mm larger than the inner diameter of the hollow cavity.

[0011] The technical effect of the utility model is mainly reflected in: the RF coaxial connector squeezes the annular ribs during the pushing process, increases friction, forms a tight connection, is not easy to fall off and shake, makes the antenna more secure after installation, and prevents the antenna from being damaged to the device interface due to shaking.

[0015] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings and embodiments. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] like Figure 1 、 2 As shown in Figure 3, a quick-plug UHF soft whip omnidirectional antenna includes a device socket 1, a matching box housing 2, a radio frequency coaxial connector 3 arranged at one end of the matching box housing 2, and an antenna assembly 4 arranged at the other end of the matching box housing 2. The device socket 1 and the radio frequency coaxial connector 3 are detachably connected.

[0017] The device socket 1 is provided with a hollow cavity 11, and the outer wall of the matching housing 2 is provided with a rubber ring 5. The outer wall of the rubber ring 5 is provided with two annular ribs 51. The end of the matching housing 2 extends into the inner cavity of the hollow cavity 11, and the annular ribs 51 are tightly connected to the inner wall of the hollow cavity 11. The outer diameter of the annular rib 51 is 0.2mm larger than the inner diameter of the hollow cavity 11. The RF coaxial connector 3 in the present invention squeezes the annular rib 51 during the insertion process, increasing friction and forming a tight connection that is not easy to fall off. This makes the antenna more secure after installation and prevents damage to the device interface caused by shaking of the antenna.

[0018] The outer wall of the matching housing 2 of the present invention is provided with two annular grooves, and the inner wall of the rubber ring 5 is provided with an annular protrusion 60 matching the annular grooves. This design can ensure that the rubber ring 5 is tightly connected to the matching housing 2.

[0019] The rubber ring 5 of the present invention is provided with a rubber plate 70 at the end of the matching housing 2. The rubber plate 70 further fills the gap, preventing shaking and making the structure of the present invention more solid. As a preferred embodiment, the rubber ring 5, annular rib 51, annular protrusion 60, and rubber plate 70 of the present invention are integrally formed.

[0020] It should be noted that the standard parts used in this utility model can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt mature conventional means such as bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the utility model author will not elaborate here.

[0021] The above describes an embodiment of the present invention in detail. However, the content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
