【Example】

 The present invention will be described in detail below based on a specific embodiment shown in the accompanying drawings. FIG. 1 shows an overview of the whole. A converter 3 with a primary radiator is arranged at a focal position of the parabolic reflector 1 via a support arm 2, and the parabolic reflector 1 is attached to a handrail 5 of a veranda by a mounting bracket 4. The light emitting portion 11 of the light emitting element is provided at a position where the converter 3 with the primary radiator is easily visible.

FIG. 2 shows an exploded perspective view of the converter 3 with the primary radiator. A light emitting element 13 having two lead wires 12 extended from the light emitting portion 11 is soldered. The printed circuit board 14 incorporating an electronic circuit that converts and amplifies the satellite signal from the primary radiator into a frequency signal is positioned below the shield frame body 15, and the screws are inserted into the through hole 17 of the shield frame body 15 and the printed circuit board. It is passed through the insertion hole 18 of 14 and screwed to the chassis 24. In addition, the integrated shield frame 15 and the printed circuit board 14 are housed in the chassis cover 23 in which the packing 22 is placed on the outward flange 21, and the screw 25 is inserted through the outward flange 21 of the chassis cover 23. It is inserted into the hole 26 and screwed into the screw hole 27 of the chassis 24. These are housed in the rear cover case 28, the chassis 24 is covered with the front cover case 29, and the engaging claws 30 of the front cover case 29 are engaged and fixed to the window holes 31 of the rear cover case 28.

Reference numeral 32 is a waterproof cap that covers the light emitting element 13 and is screwed to the chassis 24. FIG. 3 is a front view of the converter 3 with the primary radiator having the waterproof cap 32 attached, and FIG. 4 is an external view of the converter 3 with the primary radiator in which a part of the front cover case 29 of the waterproof cap 32 of FIG. 3 is broken. 5 is a cross-sectional view of the VV main part of FIG.

FIG. 5 shows details of the mounting portions of the light emitting element 13 and the waterproof cap 32. The waterproof cap 32 is formed into a hexagonal column 44 so that the upper part of the outer periphery can be attached and removed with a wrench, etc., and the thread 41 is engraved on the lower part of the outer periphery so that it can be screwed into the screw hole 43 of the chassis 24. It is a transparent or semi-transparent resin material in which the light emitting portion accommodating chamber 45 into which the light emitting portion 12 is fitted is recessed.

The adhesive 42 is applied to the threads 41 of the waterproof cap 32 and screwed into the screw holes 43, and the adhesive 42 spreads over the threads 41 and the vicinity thereof to provide a waterproof surface between the waterproof cap 32 and the chassis 24. Becomes Further, since the adhesive 42 protruding near the screw thread 41 has a waterproof function, it is not necessary to wipe it off, and the waterproof cap 32 can be easily attached. Before attaching the printed circuit board 14 to the chassis 24 with the waterproof cap 32 attached to the chassis 24 as described above, the light emitting portion 12 of the light emitting element 13 is positioned on the upper inner surface 46 of the housing chamber 45, and the lead wire 11 of the light emitting element 13 is printed. It is inserted into the insertion hole 47 of the board 14 and fixed with solder 48. As a result, the position of the light emitting section 11 of the light emitting element 13 can be accurately determined, and variation in light emission due to displacement of the light emitting section 11 can be prevented.

If the light emitting surface 49 of the outer peripheral upper end surface of the prevention cap 32 is formed parallel to the upper inner surface 46 so that the upper end portion of the prevention cap 32 does not act as a lens, the light emitting portion of the light emitting element 13 is formed. Since it is not necessary to keep 12 in contact with the upper inner surface 46 of the light emitting unit accommodating chamber 45, the light emitting element 13 can be attached to the printed board 14 by a simple jig and then fixed to the chassis 24.

As shown in FIG. 6, after the printed circuit board 14 is soldered to the chassis 24 using a jig and the light emitting element 13 is soldered and fixed to stand up, it is adhered to the screw threads 41 of the waterproof cap 32. The agent 42 is applied and screwed into the screw hole 43 of the chassis 24. Since the upper portion of the outer periphery of the waterproof cap 32 is formed as a hexagonal column 44, a spanner or the like can be used for attachment / detachment, which facilitates the work.
