Description

Technical Field

[0001] The utility model relates to the technical field of radio frequency coaxial connectors, and specifically to a conveniently twisted radio frequency coaxial connector for 5G communication equipment. Background Art

[0002] An RF coaxial connector is a connector used in radio frequency bands. It is mainly used to connect coaxial cables and RF devices for signal transmission. The outside of the RF coaxial connector consists of a cylindrical plug and socket. The plug can be inserted into the socket and rotated to lock to form a signal transmission path. The inside consists of an inner conductor and an outer conductor. The two are centered on the same axis, and an insulating medium is used as support between the inner and outer conductors. This structure is not only used to transmit signals, but also to shield electromagnetic fields, thereby maintaining a stable predetermined impedance and capacitance. Or when it is necessary to shield external electrical interference, a coaxial connector must be used for interconnection.

[0003] At present, after the RF coaxial connector used in 5G communication equipment is connected to the cable, due to the long and heavy cable, the end of the cable connected to the RF copper shaft connector is subjected to the downward gravity of the cable bending. When the cable swings, it is easy to cause the end of the RF coaxial connector connected to the cable to deform, resulting in poor contact or even damage and disconnection. To this end, we propose a RF coaxial connector that is easy to twist for 5G communication equipment. Utility Model Content

[0004] The purpose of the utility model is to provide a 5G communication device with an easy-to-twist RF coaxial connector, which can prevent the deformation of the end where the RF coaxial connector and the cable are connected due to the swing of the cable, thereby extending the service life of the RF coaxial connector and ensuring normal 5G communication. At the same time, it is also convenient for the RF coaxial connector to be twisted and connected to the 5G device, and solves the problem that after the RF coaxial connector currently used in 5G communication equipment is connected to the cable, the end where the cable and the RF copper shaft connector are connected is subjected to the downward gravity of the cable bending, which can easily cause the end where the RF coaxial connector and the cable are connected to be deformed when the cable swings, resulting in poor contact or even damage and inability to connect.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a RF coaxial connector that is easy to twist for 5G communication equipment, comprising a first tube body, a sleeve and a second tube body, the first tube body and the second tube body are rotatably installed on both sides of the sleeve, insulators are fixedly installed inside the first tube body and the second tube body, and pins and connecting tubes are fixedly penetrated inside the two insulators, a hexagonal ring is provided on the outer surface of the first tube body and the second tube body near the sleeve, an end of the second tube body facing away from the sleeve is movably connected to a fixed tube, an end of the fixed tube facing away from the second tube body is fixedly connected to a funnel-shaped rubber sleeve, and an end of the fixed tube close to the funnel-shaped rubber sleeve is fixedly connected to a plurality of steel wires in a circular array at equal intervals, and the steel wires are located inside the funnel-shaped rubber sleeve.

[0006] Preferably, annular protrusions are symmetrically provided at both sides of the interior of the sleeve, annular grooves are provided on the outer surfaces of the first tube body and the second tube body, and the two annular protrusions are respectively located inside the two annular grooves.

[0007] Preferably, an annular groove is provided inside the sleeve near the outer sides of the two annular protrusions, and sealing rings are fixedly installed inside the two annular grooves.

[0008] Preferably, an internal thread is provided on a side of the first tube body facing away from the sleeve.

[0009] Preferably, an external thread is provided on the side of the outer surface of the second tube body facing away from the sleeve, a nut is movably sleeved on the side of the outer surface of the second tube body facing away from the sleeve, four grooves are equidistantly arranged in a circular array on the side of the outer surface of the second tube body facing away from the sleeve, and a bayonet is provided on the side of each groove close to the sleeve, four elastic sheets are fixedly connected to the fixed tube body in a circular array at equal distances on the side of the outer surface of the fixed tube facing away from the funnel-shaped rubber sleeve, and a clamping block is fixedly connected to the end of each elastic sheet.

[0010] Preferably, a limiting ring is provided on the outer surface of the second tube body between the external thread and the sleeve.

[0011] Preferably, a cannula is fixedly installed inside the fixed tube, and the outer diameter of the cannula is equal to the inner diameter of the second tube body, and two ends of the cannula are respectively located inside and outside the fixed tube.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model achieves the effect of preventing the RF coaxial connector and the end of the cable from being deformed due to the swing of the cable by arranging a first tube body, a sleeve, a second tube body, a pin, a connecting tube, an insulator, a hexagonal ring, a fixing tube, a funnel-shaped rubber sleeve and a steel wire, thereby extending the service life of the RF coaxial connector, ensuring normal 5G communication, and facilitating the twisting of the RF coaxial connector and connecting it to the 5G device. The cable passes through the funnel-shaped rubber sleeve and the fixing tube, and the central conductor inside the cable is inserted into the connecting tube. The first tube body is rotated through the hexagonal ring and fixed to the interface of the 5G device. The connection between the cable and the second tube body is wrapped by the funnel-shaped rubber sleeve. When the cable swings, the funnel-shaped rubber sleeve will play a buffering role to avoid deformation of the second tube body. At the same time, the funnel-shaped rubber sleeve will also prevent dust and water vapor from entering the second tube body. The funnel-shaped rubber sleeve contains steel wire, which greatly enhances the strength of the funnel-shaped rubber sleeve, so that it has better support for the cable.

[0014] 2. The utility model achieves the effect of facilitating the disassembly and assembly of the fixed tube by arranging external threads, grooves, bayonets, clamping blocks, elastic sheets and nuts, thereby facilitating the connection and separation of the cable and the RF head shaft connector.

When the clamping block is located inside the nut, the clamping block at the end of the elastic sheet is forced to enter the inside of the bayonet, thereby completing the connection between the fixed tube and the second tube body. When disassembling the fixed tube, the nut is turned in the opposite direction, so that the nut is away from the clamping block, and the clamping block and the bayonet are separated, thus completing the disassembly of the fixed tube.

[0015] 3. The utility model provides an insertion tube, so after the fixed tube and the second tube body are connected, the insertion tube is inserted into the second tube body, thereby improving the connection strength between the fixed tube and the second tube body and being able to withstand more gravity from the downward bending of the cable.

[0016] 4. The utility model seals the joint surfaces between the sleeve and the first tube body and between the sleeve and the second tube body through the sealing ring and the annular groove, thereby preventing dust and water vapor from entering the first tube body and the second tube body through the gap between the sleeve and the first tube body and between the sleeve and the second tube body.
