Description

Technical Field

[0001] This utility model relates to the field of duplexer technology, and in particular to a duplexer with a waterproof structure. Background Technology

[0002] A duplexer is an electronic device primarily used in wireless communication systems. Its core function is to enable the simultaneous transmission of signals in two directions over a single transmission line, allowing two different signal sources to transmit on the same transmission medium. The duplexer achieves simultaneous transmission of received and transmitted signals through physical isolation and filtering techniques, ensuring that the two signals do not interfere with each other. Its working principle is based on the stopband attenuation characteristics of the signal path: the weak signal at the receiving end is coupled to the processing unit, while the high-power signal at the transmitting end is independently fed to the antenna, without interference. The duplexer is mainly composed of a helical resonant cavity and has high-frequency operating characteristics. Its core technical specification is isolation, which measures the stopband attenuation capability of the received and transmitted signals at the antenna end, directly affecting the signal transmission quality.

[0003] An existing duplexer with a waterproof structure makes it inconvenient for workers to easily install and remove protective equipment that has been used for a long time during the actual installation and protection operations. Utility Model Content

[0010] Through the above technical solution, the surface of the protective cover plate contacts the surface of the water-blocking baffle, and the front of the waterproof outer shell II contacts the rear surface of the duplexer body. These close contacts and connections make the various components of the duplexer tightly integrated to form a stable whole.

[0013] As a further improvement to the above solution, the front of the protective cover plate contacts the rear surface of the first waterproof housing, and the front of the second waterproof housing contacts the rear surface of the duplexer body.

[0014] As a further improvement to the above solution, the rear surface of the waterproof outer shell is in contact with the front surface of the duplexer body, and the number of the mounting handles is set to two, with the two mounting handles symmetrically distributed around the duplexer body.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model forms an external protective layer for the duplexer by setting up a waterproof outer shell and a waterproof outer shell, which can effectively block the intrusion of external moisture. The ingenious arrangement of the water-blocking baffle and the side water-blocking plate further enhances the waterproof effect. There are two water-blocking baffles, which are symmetrically distributed above and below the duplexer body. Their surfaces are in close contact with the surface of the duplexer body, forming a solid waterproof barrier and reducing the risk of failure caused by moisture intrusion.

[0017] This invention further seals the side gaps of the duplexer by setting a side water-blocking plate, which works in conjunction with the internal mounting groove and the connecting groove of the water-blocking partition. This prevents water from seeping in from the side, enabling the duplexer to work stably in humid or underwater environments. This greatly improves the reliability and service life of the equipment, not only increasing work efficiency but also reducing maintenance costs and time, thus enhancing the availability and reliability of the equipment.
