[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a waterproof structure for a switch and an LED, and more particularly to a waterproof structure for a switch and an LED for a remote controller for a crane.

[0002]

[Prior Art]

 The crane remote controller is a controller for remotely operating the crane, and includes a plurality of switches and LEDs. This type of controller is used in various environments. For example, it is also used when it is raining. Therefore, in a conventional controller, a plurality of switches are covered with a single rubber sheet in order to protect the switches from rain and the like. The LED was covered with a member other than this rubber sheet.

[0003]

[Problems to be solved by the device]

 As described above, conventionally, since a plurality of switches and LEDs are waterproofed by separate members, there are drawbacks that the structure is complicated and the number of assembling steps is large.

Therefore, an object of the present invention is to provide a waterproof structure capable of waterproofing a plurality of switches and LEDs together with a small number of members and easily assembled with a small number of steps.

[0005]

[Means for Solving the Problems]

 According to the present invention, in a waterproof structure for waterproofing a plurality of switches and LEDs, the plurality of switches are covered with a plurality of rubber sheets, and the window of the LED is provided between the plurality of rubber sheets. A waterproof structure of the switch and the LED, which is characterized by sandwiching the switch, is obtained.

[0006]

[Operation] In the present invention, since the plurality of switches are covered with the plurality of rubber sheets and the LED window is sandwiched between the plurality of rubber sheets, the plurality of switches and the LEDs can be combined with a small number of members. It is waterproof and can be easily assembled with a small number of steps.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. Fig. 3 shows an external view of a crane remote controller to which the present invention is applied. In FIG. 3, (a) is a plan view and (b) is a left side view. FIG. 4 shows an exploded perspective view of the crane remote controller shown in FIG. The illustrated crane remote controller is for remotely operating a crane (not shown), and has an operating unit 10 and a handle 20. The operation unit 10 is housed in an upper case 11 and a lower case 12, and the upper case 11 and the lower case 12 are fixed to each other by a plurality of screws 10a with a case ring 13 sandwiched therebetween. ing.

The operation unit 10 includes eight switches 14-1, 14-2, 14-3, 14-4, 14-5, 14-6, 14-7, and 14-8, and two LEDs 15-1 and 15. -2, which are mounted on the substrate 16. The switches 14-1 to 14-8 and the LEDs 15-1 and 15-2 are projected on the surface from a hole 11a formed in the upper case 11. The switches 14-1 to 14-8 are classified into two types, push type switches 14-1 to 14-4 and toggle switches 14-5 to 14-8. In this embodiment, the push-type switches 14-1 to 14-4 include a power switch 14-1, a horn switch 14-2, a hook storage switch 14-3, and a slow speed mode switch 14-4. ing. As the toggle switches 14-5 to 14-8, a telescopic switch 14-5 for extending and retracting the crane, a hook switch 14-6 for raising and lowering the hook of the crane, and an undulating switch 14 for raising and lowering the crane. -7 and a turning switch 14-8 for turning the crane. The LED 15-1 is a power supply LED for notifying whether the power is on or off, and the LED 15-2 is a speed LED for notifying whether the speed is the normal mode or the slow speed mode.

The operation unit 10 contains a transmitter (not shown). On the other hand, a receiver (not shown) is connected to a control unit (not shown) for controlling the crane. This transmitter wirelessly transmits an operation command from the switches 14-1 to 14-8 to the receiver. The handle 20 is a portion that is manually grasped by an operator who operates a crane, and has a hollow cylindrical shape, and a plurality of batteries (not shown) are housed in a battery case 21 inside. 3 and 4, 16 is an antenna and 22 is a strap.

As described above, since the crane may be used even in a rainy condition, the switches 14-1 to 14-8 and the LEDs 15-1 and 15-2 of the operation unit 10 are waterproofed. There is a need. Therefore, in the present invention, as will be described later, the switches 14-1 to 14-8 are covered with a plurality of rubber sheets, and the windows of the LEDs 15-1 and 15-2 are sandwiched between these rubber sheets.

With reference to FIG. 1, a method of assembling the switches 14-1 to 14-8 and the LEDs 15-1 and 15-2 of the operation unit 10 will be described. First, as shown in FIG. 1A, the switches 14-1 to 14-8 and the LEDs 15-1 and 15-2 are attached to the substrate 16. Attach the resin button knob 31 to the metal levers of the toggle switches 14-5 to 14-8 with play. The button knob 31 is made of, for example, polycarbon. FIG. 2 shows the structure of the button knob 31. As shown in FIG. 1B, the button knob 32 is inserted in the portion of the first rubber sheet 41 that covers the push-type switches 14-1 to 14-4. The adhesive 60 is applied to the surface of the button knob 31. The adhesive 60 is, for example, a silicon-based adhesive. The switches 14-1 to 14-8 and the LEDs 15-1 and 15-2 are covered with a first rubber sheet 41 via a first spacer 51. This state is shown in FIG. Next, the LEDs 15-1 and 15-2 are covered with the LED lens 33. The adhesive 60 is applied to the portion of the first rubber sheet 42 that covers the toggle switches 14-4 to 14-8. The switches 14-1 to 14-8 and the LEDs 15-1 and 15-2 are covered with the second rubber sheet 42 (FIG. 1E) via the second spacer 52 (FIG. 1D). As a result, the windows of the LEDs 15-1 and 15-2 are sandwiched between the first and second rubber sheets 41 and 42. This state is shown in FIG.

As described above, since the plurality of switches 14-1 to 14-8 are doubly covered with the first and second rubber sheets 41 and 42, the second rubber sheet 42 on the surface is damaged. Also, the plurality of switches 14-1 to 14-8 can be waterproofed with the first rubber sheet 41. Further, since the levers of the toggle switches 14-5 to 14-8 and the rubber sheets 41 and 42 are bonded with the adhesive 60, it is possible to prevent the rubber sheets 41 and 42 from expanding when the temperature rises. Further, since the button knob 31 is attached to the lever of the toggle switches 14-5 to 14-8, it is possible to prevent the rubber sheet 41 from being scratched, and the operability of the toggle switches 14-5 to 14-8 is improved. Get better. Further, since the button knob 31 is attached to the levers of the toggle switches 14-5 to 14-8 in a state in which there is some play, malfunction can be prevented. Further, since the button knob 31 is made of resin, the adhesion between the toggle switches 14-5 to 14-8 and the rubber sheet 41 is improved. In addition, the LEDs 15-1 and 15-2 and the switches 14-1 to 14-8 are double-waterproofed together by the two rubber sheets 41 and 42, so that the assembly can be easily performed with a small number of members and a small number of steps. It will be possible.
