Description

[Detailed Description of the Invention] This invention relates to an improvement of a waterproof wireless transmitter. Conventionally, as shown in Fig. 1, a printed board C with electronic components B and B mounted on a base A is attached, a protective cover D is attached to cover the printed board C, and a cover E is attached to the base via a packing F. It was a bonding structure. This protective cover D is a cover that protects the electronic components when the user removes the cover E and operates the switch G to prevent interference by changing the content of the radio waves transmitted by the wireless transmitter. Therefore, it is necessary separately from the transmitter cover E, and the width of the packing is narrow.
There were some drawbacks, such as the gaskets tending to shift sideways and were difficult to assemble. The invention of the present invention improves the above-mentioned drawbacks and provides a rainproof transmitter using an insulating cover made of an elastic insulating material that serves both the role of protecting electronic components and the role of a packing.

In the figure, reference numeral 1 denotes a base made of an insulating material, which has a recess 2 formed on the back surface, a means 4 for mounting a mounting bracket 3, a through hole 7 for a coupling screw 6 with a cover 5, and a solar cell 8 supported at the upper end. An engaging means 12 of a support body 11 having a cylindrical portion 10 that protects a printed board 9 provided with copper foil as an antenna, a protrusion 14 that guides the printed board 13, and a notch 16 in which the push button 15 is guided. It is equipped with The printed board 13 has electronic components 17, 17, . . . that constitute a circuit for transmitting radio waves.
..., switches 19, 20 for connecting a power source composed of a solar cell 8 and a capacitor 18 for storing the power generated by the solar cell 8, and depth switches 21, 21 for channel setting are attached to the circuit, and the base 1 is attached with a pin screw 22. can be attached to.
Reference numeral 23 denotes an insulating cover made of an elastic insulating material, such as rubber, which includes a packing part 24 held at the joints 1a and 5a between the base 1 and the cover 5, and an operation button 2 for the channel setting depth switch 21.
1a, a protruding hole 25, a letter 26, a notch 27 corresponding to the through hole 7, a notch 28 corresponding to the switch 19, a notch 29 corresponding to the support 11, and a sag lowering piece 30 extending along the inner surface of the base 1. and covers the electronic components 17, 17. The cover 5 has a lighting window 31 provided corresponding to the solar cell 8, a convex portion 32 that covers the support 11, a hole 34 through which the push button 33 passes, and a convex portion 5b into which the coupling screw 6 is screwed. This push button 33 has an operation piece 33a corresponding to the push button 19a of the switch 19, and a second gasket 33b. The mounting bracket 3 includes, as an example of the mounting bracket attachment means 4, projecting pieces 36, 36 that are engaged with the notches 4a, 4b of the base 1, and a square or square-shaped notch 37 that is engaged with a mounting screw. It has a cut and raised piece 38 that is coupled to the base 1.

Then, attach the printed board 13 to the base 1 with screws 22,
22, and the cover 5 is attached.
When it is attached to construction materials, it is attached using a mounting bracket 3 that fits into a recess 2 formed on the back surface of the body 1. This mounting bracket 3 is fixed to the surface of the construction material with screws 40, and the end engagement piece 36 of this mounting bracket 3,
36 into the notch 4 provided in the recess 2 on the back of the base.
a, 4a, and then attach the cut and raised piece 38 to the base 1 with the screw 32. Therefore, electricity is generated from the solar cell 8 using sunlight, and the electricity is stored in the capacitor 18 and used as a power source. When the push button 33 is pressed down, the protruding piece 33 protrudes below the push button 33.
a presses down the push button 19a of the switch 19, thereby connecting the power source to the electronic circuit.

Note that the packing part 24 of the insulating cover 23 is clamped between the base 1 and the cover 5, and a packing 33b is provided at the push button 33 to prevent water droplets from entering the transmitter.

As described above, according to the present invention, a printed board is equipped with at least electronic components constituting a radio wave transmitting circuit and a switch for connecting a battery power source to the circuit;
a base on which the printed board is mounted; an elastic insulating cover having a waterproof packing part that covers the electronic components mounted on the printed board and is clamped at the joint between the base and the cover; Since the waterproof wireless transmitter includes a cover that is joined through a gasket of the insulating cover and a push button that is exposed from the cover and operates the switch, a gasket 24 is provided on the insulating cover 23 to serve as the gasket. and electronic components 17,1
7, there is no need to provide a protective cover separately from the packing as in the conventional case, and since the packing part 24 is not a narrow width, it does not shift laterally during assembly, and the packing can reliably exert its effect. Moreover, this insulating cover has a hole 25 through which the operation button 21a of the channel setting deep switch 21 is exposed.
There is an effect that the characters 26 can be engraved and displayed near the .
