Detailed Description

It is specifically noted that, in the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise; the meaning of "several" is at least one. All directional indicators (such as up, down, left, right, front, and rear … …) in the embodiment of the present invention are only used to explain the relative positional relationship between the components, the movement, and the like in a certain posture, and if the certain posture is changed, the directional indicator is changed accordingly.

The technical solution of the present invention is further described by the following examples:

the present invention provides an antenna with waterproof performance, as shown in fig. 1, the antenna includes: a case 1, a first insulator 2, a second insulator 3, a center pin 4, and a radiator 5, the case 1, the first insulator 2, and the second insulator 3 all being hollow bodies, the first insulator 2 being fixed inside the case 1, the center pin 4 extending from the inside of the first insulator 2 to the inside of the second insulator 3, a lower end of the radiator 5 being inserted into the inside of the second insulator 3, and a lower end of the radiator 5 being in contact with an upper end of the center pin 4; in the present invention, an antenna includes: as shown in fig. 2, the waterproof rubber ring 6 has a waterproof groove 11 which is open downward on the outside of the housing 1, a part of the waterproof rubber ring 6 is embedded in the waterproof groove 11, and the other part of the waterproof rubber ring 6 is located below the waterproof groove 11.

The housing 1 is used to be fixed on a casing 100 of the device, the first insulator 2 and the second insulator 3 are used to block signals, and the center pin 4 is used to transmit signals with the radiator 5. When the antenna is installed in the device, the lower end of the housing 1 penetrates the casing 100 of the device, and the waterproof rubber ring 6 contacts the outer surface of the casing 100, thereby achieving a waterproof effect.

Therefore, the antenna with the structure has good waterproof performance on one hand, and can prevent rainwater, water vapor or other liquid from entering the inside to cause damage; on the other hand, the shell can be inserted into the shell, so that the problem that the antenna falls off due to collision or other reasons is avoided.

Specifically, in the present embodiment, the outer surface of the housing 1 has a waterproof collar 12, and the waterproof groove 11 is provided on the lower surface of the waterproof collar 12. Of course, in other embodiments, a waterproof boss (i.e. the cross section of the housing 1 is stepped) may be provided outside the housing 1, and the waterproof groove 11 is provided on the lower surface of the waterproof boss, which has a higher pressure resistance but is more material-consuming than the waterproof protruding ring 12.

Specifically, the antenna further includes: and a nut 7, wherein the outer surface of the shell 1 is provided with a mounting thread 13, the mounting thread 13 is positioned below the waterproof groove 11, and the nut 7 is engaged with the mounting thread 13. When the antenna is installed in the device, the nut 7 is located inside the device case 100, and the waterproof rubber ring 6 is pressed by applying force from inside to outside, and the housing 1 is further fixed. Further, since the nut 7 is located inside the apparatus case 100, the user cannot remove the antenna from the outside, making the antenna less likely to be damaged from the outside.

More specifically, the antenna further includes: and the spline washer 8 is positioned between the mounting thread 13 and the waterproof groove 11. The spline washer 8 plays a role in increasing the pre-tightening elasticity for locking the nut 7, and the nut 7 is prevented from loosening.

Specifically, the radiator 5 has a radiation end 51, a connection rod 52 and a positioning end 53, the connection rod 52 has an upper end connected to the radiation end 51 and a lower end connected to the positioning end 53, and the positioning end 53 is inserted into the second insulator 3.

More specifically, the outer surface of the positioning end 53 has a positioning thread 54, the upper end of the second insulator 3 has a positioning groove 31 opened upward, the inner surface of the positioning groove 31 has a fitting thread 32, and the positioning thread 54 is engaged with the fitting thread 32.
