Description

Fast assemblable parabolic antenna

The present invention relates to a prefabricated parabolic antenna capable of minimizing portable volume. In assembling a plurality of dividers into one reflector, the assembly of the dividers can be performed quickly, accurately, and firmly. A prefabricated parabolic antenna is provided.

In the case of a satellite communication terminal, a high gain antenna is required for long distance communication with a satellite, and a reflector antenna is mainly used as the high gain antenna. Among the reflector type antennas, the most basic type of antenna is a parabolic antenna in which a feed horn is located at the focal point (center) of the reflector. ), The radio waves radiated from the focus are reflected at the surface of the reflector and sent out in the desired direction (transmission).

Parabolic antennas made of metal with good reflectivity, such as aluminum, are made to a certain size or more, so they are not limited to the size or weight of the antenna because they are installed in buildings such as base stations or mounted on vehicles. .

However, in case of using satellite communication for communication with the operation unit penetrating the rear of the enemy, the parabolic antenna used in connection with the satellite communication terminal should be miniaturized and lightened so that the bottle is suitable for carrying. Size and weight are considered very important factors.

As part of improving the portability of the antenna, for example, JP-A-87-7429 (Assembly Parabolic Antenna, Venus Co., Ltd.) disassembles the reflector into several pieces when carrying and storing them, and re-uses these pieces when used. A method of assembling has been proposed. However, the assembly antenna of such a conventional configuration has to assemble bolt-nuts as many as 32 times, so the assembly time is very long. In addition, since the metal bolt-nut and the supporting rod must be provided, there is a disadvantage that it is heavy to carry. In addition, since the bolt-nut is fastened through the reflecting plate piece, the surface of the reflecting plate piece pressed by the bolt-nut is distorted.

The present invention is designed to improve the problems of the conventional parabolic antenna of the configuration, as well as the assembly and disassembly of the dividers divided into several pieces is made quickly, the honeycomb core (honycomb core) and the fabric ( fabric) It is convenient to carry by reducing the weight of the antenna while maintaining the robustness of the antenna by keeping the partition plate made of composite material of skin, and it is distorted on the surface of the partition plate by using a fixing band for assembling and disassembling the partition plates. It is an object of the present invention to provide a fast-mounting prefabricated parabolic antenna that does not occur.

In order to achieve the above object, the fast-fastening type parabolic antenna according to the present invention is a reflection plate, consisting of a mount disposed in the center and a plurality of dividers closely assembled along the circumference of the mount, the front of the mount ( It may include a feed horn detachably assembled to the front surface, and a plurality of fixing bands disposed on the rear surface of the reflecting plate for elastic fastening between the mount and the plurality of partition plates.

When the assembly is completed, the mount located at the center of the antenna has a feed mixing portion formed on the front surface, an antenna support coupling portion formed on the rear surface, and a plurality of rings spaced apart from each other along the circumference of the rear surface. It is preferable that the locking portion is formed, and a plurality of pairs of fitting grooves are formed in the form of two pairs along the circumferential surface of the mount so as to be located at both sides of the hooking portion. In the embodiments described below, the mount of the present invention is shown in a regular hexagon.

In addition, in the plurality of partition plates which are closely assembled to the mount, the mount fitting pieces are formed on the inner end surface in contact with the circumferential surface of the mount, and the side fitting grooves are formed on either side of both sides in contact with the other partition plates. Side portion fitting is formed on the other side while the addition is formed, it is preferable that the configuration is formed on the rear bracket bracket. More preferably, for weight reduction of the antenna, each divider is made of a honeycomb core, a fabric skin made wider than the honeycomb core and bonded to both sides of the honeycomb core, and at least one fabric for reflecting radio waves. By a conductor filling surface formed on the surface of the skin, a guide piece inserted into the space between the honeycomb core and the fabric skin as a component for forming the side fitting groove, and a filler filling between the guide piece and the honeycomb core. It is composed. In the embodiments described below, the dividers are congruent with each other and the shape is shown in a fan shape.

In addition, the fixing band according to the present invention, a bracket having a fixing hole for engaging the bracket engaging portion of the partition plate, and a plurality of spaced apart from each other along the circumference of the bracket for a secure fastening with the other partition plate and the mount It is preferable that it is a structure containing a connection part. In the embodiments described below, the connecting portion to be engaged with the hooking portion of the mount, it is shown that the ring is installed at the free end of the expansion belt. In addition, the connecting portion connected to the connecting portion of the fixed band provided on the other divider, it is shown that the accommodation buckle or the insertion buckle is provided at the free end of the expansion belt.

According to the present invention, since the parabolic antenna for satellite communication can be separated into several pieces of partition plates, mounts, and feed horns, the portable volume of the antenna can be reduced.

In addition, the side plate pieces and the side fitting grooves formed on both sides of the divider plate can be assembled quickly and accurately.

Further, by inserting the mount fitting pieces formed on the inner end surface of the dividing plate into the fitting grooves formed on the circumferential surface of the mount, the plurality of dividing plates can be assembled to the mount quickly and accurately in a state of being in intimate contact with each other.

In addition, since the reflector plate consisting of a plurality of dividers and mounts is easily assembled or disassembled by snap coupling or snap release between the fixing bands disposed on the rear surface of the reflector, the assembly and disassembly time is shorter than before. .

In addition, since the partition plate is made of a composite material of the honeycomb core and the fabric skin, the portable weight of the antenna can be reduced.

In addition, since the honeycomb core has a higher strength and lighter weight than an aluminum plate, the honeycomb core is excellent in maintaining the shape of the partition plate or the reflecting plate against impact from the outside.

In addition, when assembling a plurality of dividers and mounts, since only the fixing band is used instead of the bolt-nut, the surface of the reflecting plate is not distorted.
