The dust in the connector is difficult to clean, and the dust attached in the radio frequency connector forms a bad contact point between the connector after the radio frequency connector is connected with the connecting line, which may cause the isolation degree between different paths to drop or cause physical damage to the connector. The reliability of the device is low, and the practicability is low. UTILITY MODEL CONTENT

[0005] The utility model aims at providing a radio frequency switch with isolating device to solve the problems in the above background.

[0007] Preferably, the outer connecting hole is a circular hole structure, and the inner diameter of the outer connecting hole is equal to the outer transmission conductor. The outer transmission conductor is fixedly connected with the inner transmission conductor through the inner connecting hole formed in the upper isolating plate.

[0008] Preferably, the inner transmission conductor is in cylindrical structure, the inner transmission conductor is fixedly connected with the upper isolating plate, the inner transmission conductor is contacted with the signal transmission connector, the signal transmission connector is arranged on the radio frequency switch main body, and the buffer pad is fixedly connected to the bottom of the radio frequency switch main body.

[0009] Preferably, one end of the limiting rod is fixedly connected to a limiting plate, the limiting plate is a circular plate structure, a spring is fixedly connected to the limiting plate, the other end of the spring is fixedly connected to the upper isolation plate, and an RF connector is fixedly connected to the upper isolation plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model proposes an RF switch with an isolation device. By rotating the connector on the connecting wire and removing the connecting wire, a spring pulls the limiting plate and the limiting rod to move along the limiting hole opened on the upper isolation plate. The limiting rod pushes the protection plate upward, causing the protection plate to detach from the external transmission conductor. The elastic protective pads, no longer squeezed by the external transmission conductor, return to their original shape. The four elastic protective pads, having returned to their original shape, seal the external connection hole opened on the protection plate, isolating the external transmission conductor within the signal transmission connector, thus protecting the external transmission conductor. When the device is not in use, the protection plate and elastic protective pads effectively prevent external dust from adhering to the external transmission conductor, which could lead to poor contact points between connectors and a decrease in the isolation between different paths. It also prevents dust from causing physical damage to the connector, improving the reliability of the device. Attached Figure Description
