BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof structure suitable for an electronic device, particularly a small-sized communication device mounted on a vehicle, and more particularly to a waterproof structure using a packing at a joint between a communication device main body and an operation panel.

[0002]

2. Description of the Related Art Conventionally, a connection between a radio communication device main body and an operation panel in this type of device is made by inserting a rubber elastic packing into a joint between the radio communication device main body and the operation panel, and via the packing. It was tightened using a plurality of screws to provide a waterproof structure.

[0003]

However, there is a problem in appearance since the fastening screw is noticeable as a screw head on the surface of the operation panel. Further, since the screw portion occupies a predetermined area on the surface of the operation panel, it is a restriction when arranging other components. For this reason, there is a problem that there is a restriction in the design of the appearance of the wireless device itself.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problem, and in order to achieve the object, an electronic device main body and an operation panel are attached to each other by using a screw through an elastic packing and the packing is attached. In the water-proof structure of an electronic device that is pressed and waterproofed, the direction of the hole is such that the packing presses the packing.
A screw hole substantially orthogonal to the direction is provided in the electronic device body,
Screw into the screw inserted in the screw hole, and
A clamping tool having an inclined slope.
The first projection having a slope approximately the same as the slope of the tool
The operation panel is characterized in that it is provided on the operation panel . Also tilt
A hook having a hooked portion is provided on the electronic device body,
It has a slope that is almost the same as the slope of the latching part of the latch.
A second projection provided on the operation panel.
You. In addition, the stopper surface for the operation panel
Provided in the electronic device body, the force for pressing the packing is
It is characterized by being appropriately restricted.

[0005]

[Action] packing in operation tightening the direction of the screw is orthogonal to the direction of pressing and by pressing the collision force that have a similar slope with a slope clamp is provided on the operation panel, the elastic packing It is pressed between the wireless communication device main body and the operation panel to obtain a reliable waterproof structure. In addition,
A single screw by providing a tool and a second protrusion.
The packing is surely pressed by the attachment. In addition, stopper
Surface to properly press the packing.
Limited.

1 and 2 show an embodiment of the present invention.
This will be described in detail with reference to FIG. In the drawing, for example, an operation panel 1 made of a plastic material is connected to a wireless communication device main body 2 also made of a plastic material via a ring-shaped packing 3 made of an elastic material such as rubber and waterproofed. Achieve structure.

[0007] The metal communication device main body 2 has a hook 4 made of metal or the like.
Are fixed, and an upper projection 5 for engaging with a slope 9 formed on the latch 4 is formed integrally with the operation panel 1. In addition, an opening for penetrating the screw 6 is formed in the lower projection 7 formed integrally with the operation panel 1.

Next, the operation of the waterproof structure having such a configuration will be described. First, the packing 3 is attached to the operation panel 1.
Is mounted, the upper projection 5 of the operation panel 1 is hooked on the latch 4 provided on the wireless communication device main body 2, and the operation panel 1 and the wireless communication device main body 2 are united.

After the screw 6 is passed through a screw hole provided in the wireless communication device main body 2 and inserted into an opening provided in the lower projection 7 of the operation panel 1, a spring 12 is mounted. Thereafter, the fastener 11 having the slope 8 is screwed into the screw 6. In order to prevent the fastener 11 from falling off, a retaining ring 13 is attached and fixed to the tip of the screw 6.

In this state, when the screw 6 is tightened, the fastener 11 is gradually tightened against the elastic force of the spring 12, and the slope 8 comes into contact with the surface of the lower projection 7 having the same slope. . Thereafter, when the screw 6 is tightened, the operation panel 1 is pressed in the direction of arrow A shown in FIG. 2 until it hits the stopper surface 14 of the wireless communication device main body 2. At this time, since the inclined surface 8 is formed on the tightening tool 11, a force is applied to the operation panel 1 to move in the direction of arrow B shown in FIG. 2, and the packing 3 is pressed in the direction of arrow B. Further, since the lower portion of the operation panel 1 contacts the stopper surface 15 of the wireless communication device main body 2 and does not move any further, a predetermined pressing force can be applied to the packing 3.

[0011]

As described above, according to the present invention, a reliable waterproof structure between the wireless communication device main body and the operation panel can be obtained by using only one screw, and the screw can be wirelessly communicated. Since it is provided at a position such as the bottom portion that is not noticeable in the appearance of the machine body, an aesthetic appearance is obtained, and the degree of freedom in designing the product is increased.
