Description

Technical Field

[0001] This utility model belongs to the field of radio frequency cable converter technology, specifically relating to a waterproof radio frequency cable adapter. Background Technology

[0002] RF connectors have been developing towards higher speed, integration, and faster speed for many years. The emergence of cluster connectors has enabled faster and more efficient signal transmission. However, the size of cluster connectors limits the types of cables that can be used with them. Cables exceeding a certain size cannot be installed with cluster connectors. When it is necessary to use large-diameter cables with lower loss, cluster connectors cannot be used. In order to enable cluster connectors to use large-size cables, RF cable adapters are needed to connect large-size cables with small-size cables, thus realizing the connection between cluster connectors and large-size cables.

[0003] Existing RF cable adapters suffer from poor sealing when connecting large-diameter and small-diameter cables, leading to water ingress at the connection points and causing the adapters to malfunction and become unreliable. To address this, we propose a waterproof RF cable adapter. Utility Model Content

[0004] The purpose of this invention is to provide a waterproof radio frequency cable adapter to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof radio frequency cable adapter, comprising,

[0006] A first outer casing, inside which a large-diameter cable is connected via a first insulator;

[0007] The second housing contains a small-diameter cable connected inside via a second insulator;

[0008] A threaded sleeve is used to connect the first outer shell and the second outer shell;

[0009] A sealing ring is provided between the first outer shell, the second outer shell, and the screw sleeve.

[0010] Preferably, a first step is provided on the inner side of the first housing, and the first insulator is snapped into the first step inside the first housing.

[0011] Preferably, the first housing has a socket for connecting the large-diameter cable and the small-diameter cable.

[0012] Preferably, the first housing is further provided with a third insulator located outside the socket.

[0013] Preferably, a second step is provided inside the first housing, one end of the third insulator is engaged with the second step, and the other end of the third insulator abuts against the second housing and the second insulator.

[0014] Preferably, a third step is provided on the end of the first outer shell facing the second outer shell, and the end of the second outer shell facing the first outer shell is engaged in the third step.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] In this invention, a large-diameter cable is connected to the first housing via a first insulator, and a small-diameter cable is connected to the second housing via a second insulator. The first and second housings are connected by a threaded sleeve. A sealing ring is provided between the first housing, the second housing, and the threaded sleeve. In use, the large-diameter cable is connected to the first housing via the first insulator, and the small-diameter cable is connected to the second housing via the second insulator. Then, one end of the second housing is inserted into the socket inside the first housing. At this time, the sealing ring is located between the first housing, the second housing, and the threaded sleeve. The first and second housings are then tightened using the threaded sleeve. This achieves the connection between the large-diameter and small-diameter cables and seals the RF cable converter, improving its waterproof performance and reliability, preventing water from entering the connection points, and ensuring the normal operation of the RF cable converter.
