Description

Technical Field

[0001] This utility model relates to the field of radio frequency connector technology, specifically a shielding sleeve for radio frequency connectors. Background Technology

[0002] In today's rapidly developing wireless communication technology, RF connectors are an indispensable component of wireless communication equipment. Their performance directly affects the signal transmission quality of the entire communication system. RF connectors are typically used to connect cables and equipment to achieve the transmission of RF signals. In existing RF connector designs, shielding sleeves are usually used to improve the connector's electromagnetic compatibility and prevent signal interference. Shielding sleeves can effectively reduce external interference signals from entering the connector and prevent internal signals from radiating outward, ensuring stable signal transmission. Currently, most shielding sleeves are fixed with threads when connected to RF connectors. However, under harsh environments such as vibration and impact, threaded connections are prone to loosening, leading to a decrease in shielding effectiveness and affecting signal transmission quality. Furthermore, disassembling threaded shielding sleeves is relatively difficult, increasing maintenance costs and complexity. Utility Model Content

[0003] The purpose of this invention is to provide a shielding sleeve for radio frequency connectors to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a shielding sleeve for an RF connector, comprising a connector body, a transmission line being snapped onto one end of the connector body, a sleeve body being rotatably connected to the outer surface of the transmission line, a turntable being fixedly connected to the outer surface of the sleeve body, a limiting groove being formed inside the connector body, a limiting block being fixedly connected to the outer surface of the sleeve body, an L-shaped plate being fixedly connected to the outside of the connector body, a connecting plate being fixedly connected to the outer surface of the turntable, a bolt being fixedly connected to one side of the connecting plate, and a nut being threaded onto the external thread of the bolt.

[0005] As a further preferred embodiment of this technical solution, an auxiliary block is fixedly connected to the outer surface of the connector body, and a sealing ring is fixedly connected to the inner surface of the connector body.

[0006] As a further preferred embodiment of this technical solution, the sleeve body is snapped into the connector body, and the sealing ring overlaps with the sleeve body.

[0007] As a further preferred embodiment of this technical solution, the limiting block is engaged in the limiting groove, and the turntable overlaps with the connector body.

[0008] As a further preferred embodiment of this technical solution, the connecting plate overlaps with the L-shaped plate, and a guide groove is provided in the L-shaped plate.

[0009] As a further preferred embodiment of this technical solution, the bolt is engaged in the guide groove, and the bolt is connected to the L-shaped plate by a nut.

[0010] This utility model provides a shielding sleeve for radio frequency connectors, which has the following advantages:

[0011] (1) This utility model sets up a sleeve body, a turntable, an L-shaped plate, a connecting plate, bolts and nuts. The turntable drives the sleeve body to rotate on the surface of the transmission line, while the limiting block will be locked into the limiting groove. The bolt on the front of the connecting plate will slide in the guide groove. When the connecting plate overlaps with the L-shaped plate, the bolt is threaded to the L-shaped plate through the nut. The shielding sleeve, through the cooperation between the L-shaped plate, bolts and nuts, enables the transmission line to be quickly assembled with the connector body through the sleeve body, avoiding loosening under harsh environments such as vibration and impact, ensuring its shielding effect and signal transmission quality, and facilitating the disassembly and assembly of the transmission line, thereby reducing the subsequent maintenance cost and difficulty.

[0012] (2) By setting a limiting block and a limiting groove, when the turntable is attached to the right end of the connector body, the sealing ring will contact the surface of the sleeve body. The turntable drives the sleeve body to rotate on the surface of the transmission line, and the limiting block will be engaged in the limiting groove. The limiting block and the limiting groove play a certain limiting role in fixing the sleeve body, and prevent the sleeve body from shifting its position when it is fixed.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] This utility model provides a technical solution: such as Figure 1 and Figure 4 As shown, in this embodiment, a shielding sleeve for an RF connector includes a connector body 1, a transmission line 2 is snapped onto one end of the connector body 1, a sleeve body 4 is rotatably connected to the outer surface of the transmission line 2, a turntable 5 is fixedly connected to the outer surface of the sleeve body 4, a limiting groove 8 is formed inside the connector body 1, a limiting block 7 is fixedly connected to the outer surface of the sleeve body 4, an L-shaped plate 9 is fixedly connected to the outside of the connector body 1, a connecting plate 10 is fixedly connected to the outer surface of the turntable 5, a bolt 12 is fixedly connected to one side of the connecting plate 10, and a nut 13 is threaded onto the bolt 12.

[0021] By setting the sealing ring 6, when the turntable 5 is attached to the right end of the connector body 1, the sealing ring 6 will contact the surface of the sleeve body 4, so that the sealing ring 6 can seal the fixed area between the sleeve body 4 and the connector body 1, preventing impurities in the external air from seeping into the interior of the connector body 1 and ensuring the service life of the connector body 1.

[0022] like Figure 4 As shown, the connecting plate 10 overlaps with the L-shaped plate 9. The L-shaped plate 9 has a guide groove 11. The bolt 12 is engaged in the guide groove 11. The bolt 12 is connected to the L-shaped plate 9 through the nut 13.

[0023] By setting the guide groove 11, when the turntable 5 drives the sleeve body 4 to rotate on the surface of the transmission line 2, the bolt 12 on the front of the connecting plate 10 will slide in the guide groove 11, so that the guide groove 11 plays a certain positioning role in fixing the bolt 12 and avoids the bolt 12 from bumping when rotating.

[0024] This utility model provides a shielding sleeve for radio frequency connectors, and its working principle is as follows:

[0025] When the transmission line 2 is connected to the connector body 1, the transmission line 2 will drive the sleeve body 4 to be snapped into the connector body 1, and the limiting block 7 on the surface of the sleeve body 4 will slide in the limiting groove 8. When the turntable 5 is attached to the right end of the connector body 1, the sealing ring 6 will contact the surface of the sleeve body 4. The turntable 5 will drive the sleeve body 4 to rotate on the surface of the transmission line 2, and the limiting block 7 will be snapped into the limiting groove 8. The bolt 12 on the front of the connecting plate 10 will slide in the guide groove 11. When the connecting plate 10 overlaps with the L-shaped plate 9, the bolt 12 will be threadedly connected to the L-shaped plate 9 through the nut 13.
