Description

Technical Field

[0001] The utility model belongs to the technical field of signal transmission mechanisms, and in particular relates to a novel coaxial microwave transmission line protection mechanism. Background Art

[0002] Coaxial microwave transmission line, referred to as coaxial line, is a special microwave transmission line used to transmit electromagnetic wave signals in the microwave frequency band. Its basic principle is to use the transmission characteristics of electromagnetic waves in the medium to achieve signal transmission through the changes in voltage and current on the transmission line. Coaxial line is a double-conductor transmission line, consisting of two coaxial cylindrical conductors, with air or high-frequency medium filled between the inner and outer conductors.

[0003] In a coaxial microwave transmission line, the electromagnetic field is confined between the inner and outer conductors, thereby basically avoiding radiation loss and making it almost unaffected by external signals. In addition, the main waveguide mode in the coaxial line is TEM (transverse electromagnetic wave), but it can also transmit TE (transverse electric) mode and TM (transverse magnetic) mode, with a cutoff frequency of zero and a corresponding cutoff wavelength tending to infinity.

[0004] The existing coaxial microwave transmission line is soft, has a small bending radius, and has no protective sleeve to support it. This makes it easy for the cable to get tangled or excessively bent. The standing wave ratio is large at the location where the knot or bend is serious, and the energy loss is large, which will cause heat and damage the cable. If the traditional protective sleeve is used for installation and locking, its structure is complex, the volume is large, and the cost is high. Utility Model Content

[0007] The technical solution adopted by the utility model is as follows:

[0008] A novel coaxial microwave transmission line protection mechanism comprises a heat dissipation column and a microwave cable, wherein the heat dissipation column is sleeved on the microwave cable, one end of the heat dissipation column is connected to a radio frequency connector, the interior of the radio frequency connector is threadedly connected to the outer side of the end of the heat dissipation column, the other end of the heat dissipation column is connected to a fixed end cover, the fixed end cover is fixedly connected to the end surface of the heat dissipation column by a plurality of screws, the fixed end cover is provided with a cable hole for passing the microwave cable, a protective sleeve is wound around the microwave cable, and the protective sleeve is composed of a PVC cable protective sleeve structure.

[0009] Furthermore, a portion of the end of the protective sleeve is installed between the microwave cable and the heat dissipation column, and the other portion of the protective sleeve completely covers the entire microwave cable.

[0010] Furthermore, a mounting groove is provided between the fixed end cover and the heat dissipation column, a silicone ring is installed in the mounting groove, the depth of the mounting groove is smaller than the thickness of the silicone ring, with a difference of 1mm to 2mm, and the silicone ring is sleeved on the outside of the protective sleeve.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
