Description

Satellite antenna LNB holder {Satellite antenna LNB holder}

The present invention relates to a satellite antenna LNB fixing device capable of easily fixing an LNB (Low-Noise Block converter low-noise amplifying converter) used in a satellite antenna and at the same time facilitating a change of a polarization angle (SKEW angle) of an antenna. .

A low-noise block converter (LNB) is installed in a satellite antenna and amplifies the radio wave received by the satellite antenna and converts it to a standardized intermediate frequency.

In general, the LNB is manufactured integrally with the feed horn used in the antenna to improve reception efficiency. of LNB had to be used. However, the flange-type LNB is relatively expensive and there are not many products, so a method of cutting only the feed horn portion from the conventional LNB in which the feed horn is integrated and then coupling the LNB to the rear of the antenna is mainly used.

In the case of coupling the LNB with the feed horn cut out to the rear of the antenna, a separate bracket is made to fix the LNB, and then the cut part (feeder) of the LNB is inserted into the bracket, and the LNB feeder is inserted in the direction in which the LNB is inserted. The LNB was fixed by inserting a set screw through the outside of the bracket in a vertical direction based on the , pressurizing the feeder inserted into the bracket.

In the above method, when it is necessary to replace the LNB with another type, it is necessary to manufacture/install a new standard bracket, and there is a problem that a separate tool is required for dismantling the set screw for disassembling the LNB and the bracket. . In addition, the LNB needed to change the polarization angle (SKEW angle) according to the location where the antenna is installed and the positional relationship with the satellite. After loosening the LNB, it is necessary to rotate the LNB and tighten the screw again, so there is a problem in that it is relatively difficult to control the polarization angle of the LNB, and there is a problem that the set screw itself causes damage to the feeder.

As shown in FIG. 5 , the screw thread 220 of the first engaging portion 200a is screwed to the thread 120 of the fixed coupling portion 100 coupled to the antenna, and the fixed coupling portion 100 and the engaging portion are engaged. The parts 200 may be coupled to each other, and the user may adjust the degree of fixing of the LNB 10 in which the feed horn is integrated by adjusting the degree to which the locking coupling part 200 is screwed to the fixing coupling part 100 . .

Hereinafter, a method for fixing the LNB 10 in which the feed horn is integrated using an embodiment of the present invention will be described in detail.

As shown in FIG. 6 , the first engaging portion 200a and the second engaging portion 200b are disposed to surround the feeder 13 and then coupled to each other so that the feeder 13 is placed in the inner space of the engaging portion. to be located At this time, since the diameter of the cut and remaining feed horn 11 located at one end of the feeder 13 is larger than the internal space of the engaging portion, the first engaging portion 200a and the second engaging portion 200b are separated from each other. Unless it does, the engaging portion 200 does not separate from the feeder 13 .

7 shows a state in which the engaging portion 200 coupled to the feeder 13 of FIG. 6 is coupled to the fixed coupling portion 100, but only the first engaging portion 200a is shown for convenience of explanation. will be.

As shown in FIG. 7 , the first engaging portion 200a is screw-coupled to the fixed coupling portion 100 in a state in which the feeder 13 is inserted. As the degree to which the engaging portion is screwed increases, the space between the fixed engaging portion 100 and the engaging portion becomes narrower, and eventually the cut feed horn 11 positioned at one end of the feeder 13 is fixedly coupled. It is pressed and fixed by the portion 100 and the engaging portion. That is, the user has only the fixed coupling part 100 coupled to the antenna without a special tool, and after cutting the feed horn from the LNB in which various types of feed horns are integrated through the engaging coupling part 200, through the above-described process The LNB can be easily coupled to the antenna.

In the case of the present invention, it is easy to change the polarization angle of the LNB. When the antenna to which the present invention is coupled is used in different regions, it is necessary to change the polarization angle of the LNB. In this case, the user rotates the engaging part 200 to loosen the fixed coupling part 100 and the screw coupling to a certain extent. After allowing the horn to move the integrated LNB 10, rotate the LNB 10 as much as necessary and tighten the engaging portion 200 again to fix the LNB 10 with the integrated feed horn to fix the LNB 10 polarization angle of the LNB. can be changed.
