The packing 3 is pressed by the operation panel 1 against the electronic device body 2 by tightening the.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 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 connecting portion between a main body of the communication device and an operation panel.

[0002]

[Prior art]

 Conventionally, the connection between the main body of the wireless communication device and the operation panel in this type of device has been made by inserting a rubber elastic packing into the joint between the main body of the wireless communication device and the operation panel, and inserting a plurality of screws through the packing. It was tightened by using a waterproof structure.

[0003]

[Problems to be solved by the device]

 However, there was a problem in appearance because the tightening screw was conspicuous as a screw head on the surface of the operation panel. Further, the screw portion occupies a predetermined area on the surface of the operation panel, which is a restriction when arranging other parts. For this reason, there is a problem in that there is a restriction on the design design of the radio itself.

[0004]

[Means for Solving the Problems]

 The present invention has an object to solve the above-mentioned problems, and in order to achieve the object, in a waterproof structure in which an electronic device main body and an operation panel are waterproofed with a screw through an elastic packing, the screw is attached to the electronic device. It is characterized in that the packing is pressed against the electronic equipment body by the operation panel by providing it in a part that is not noticeable in appearance and tightening the screws.

[0005]

[Action]

 By tightening a single screw, the elastic packing presses between the main body of the wireless communication device and the operation panel by the tightening tool with the slope pressing the lower protrusion with the equivalent slope provided on the operation panel. And obtain a reliable waterproof structure.

[0006]

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. In the figure, 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. Connect and achieve waterproof structure.

A metal fitting 4 is fixed to the wireless communication device main body 2, and an upper protrusion 5 for engaging with a slope 9 formed on the metal fitting 4 is integrally formed on the operation panel 1. Has been done. Further, an opening for penetrating the screw 6 is formed in the lower protrusion 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, and the upper protrusions 5 of the operation panel 1 are hooked on the metal fittings 4 provided on the wireless communication device main body 2 to combine the operation panel 1 and the wireless communication device main body 2.

After inserting the screw 6 into a screw hole provided in the wireless communication device main body 2 and inserting it into the opening provided in the lower protrusion 7 of the operation panel 1, the spring 12 is mounted. After that, the fastener 11 having the inclined surface 8 is screwed into the screw 6. In order to prevent the tightening tool 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 tightening tool 11 is gradually tightened against the elastic force of the spring 12, and the inclined surface 8 has the same inclined surface as the surface of the lower protrusion 7. Abut. After that, when the screw 6 is tightened, the operation panel 1 is pressed in the direction of arrow A shown in FIG. 2 until it touches the stopper surface 14 of the wireless communication device body 2. At this time, since the inclined surface 8 is formed on the tightening tool 11, the operation panel 1 exerts a force to move in the arrow B direction shown in FIG. 2, and therefore the packing 3 is pressed in the arrow B direction. Further, since the lower part of the operation panel 1 comes into contact with 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]

[Effect of device]

 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 used on the external appearance of the wireless communication device main body. Since it is installed at a position such as the bottom that is not conspicuous, it gives an aesthetic appearance and increases the degree of freedom in product design and design.
