Description

[Detailed description of the invention] The present invention relates to a drip-proof casing for use in wireless communication equipment, particularly for use in vehicles (hereinafter abbreviated as in-vehicle use).
The present invention relates to a housing for a wireless communication device.

Generally, a wireless communication device used in a vehicle is composed of a main body housing so-called internal components, and an operation section located at the front of the main body that incorporates operating parts for controlling various operations. However, conventional devices have separate casings for the main body and operation section, and these are electrically connected using connectors, etc., and structurally, the respective casings are directly screwed together. was the majority. These general in-vehicle wireless communication devices are becoming smaller due to the use of ICs in their internal parts, and if necessary, they can be removed from the car, or if they have a built-in battery power source, they can be used as portable devices. There are many ways to use it. In this case, the wireless communication device must not only be smaller and lighter, but also drip-proof. However, as mentioned above, it is difficult to provide a drip-proof property with a conventional general vehicle-mounted wireless communication device in which the operating section is directly screwed onto the main body. As a typical example of a conventional drip-proof structure, as shown in FIG.
A mounting plate 33 having a packing 34 between the joints with the
The operation part 31 and the main body part 32 are fastened to each other by sandwiching them between them, and the structure is such that the gasket provides drip-proof properties. In this case, the operating section and the main body are each independently configured to have a drip-proof structure. In other words, the parts 35 are attached to the operation section 31 in a drip-proof manner, and the main body section 32 is also made drip-proof by sealing the joints of the covers 36 on the upper and lower surfaces with gaskets or the like.
When these respective casings 31 and 32 are connected, the structure is such that the joints are sealed with a gasket 34 or the like. In such a structure, it is undesirable to manufacture the operating section each time to accommodate the presence or absence of various operating parts and differences in function display due to increasingly diversified customer requirements, as this increases costs. Looking only at the operating section, the operating parts protruding from the front of the operating section that are unnecessary due to specifications can be adequately covered with blind plates unless they have a drip-proof structure.

The present invention eliminates the drawbacks of the conventional structure as described above, and allows the diversification of customer specifications by simply attaching the components to be mounted on the operating section to a plate and attaching this operating component mounting plate to the main body. It is an object of the present invention to provide a casing for a communication device that has drip-proof properties that can be easily applied.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is an exploded perspective view of a drip-proof housing for a wireless communication device according to an embodiment of the present invention in the order of assembly, and FIG. 2 is a side sectional view of the assembled state. In these figures, reference numeral 1 denotes the main body housing of the wireless communication device, and the inside of the housing includes partition members 2, shelves 3, or bosses 4 provided for mounting internal devices.
etc. The main body casing 1 has front, rear, left and right sides formed by a frame whose top and bottom surfaces are open. The left and right sides of the frame are provided with grooves 5 for engaging with mounting brackets when mounted on a vehicle, and uneven portions 6 for heat radiation, etc. Furthermore, the front surface of the frame, that is, the joint surface 7 with the operation section, is provided with an antenna. A storage tube 8 and a handle storage boss portion 9 are formed, and an open hole 10 is drilled through these portions. A groove 12 in which an O-ring packing 11 is embedded is formed at the edge of the open hole 10. Reference numerals 13 and 13' designate covers that close the upper and lower opening surfaces of the frame body, and grooves 15 are formed around the inner surface of the covers in which O-ring gaskets 14 and 14' are embedded. Cover 13, 13'
Attach the screw 16 to the frame through the gaskets 14 and 14'.
Attached by. If necessary, reinforcing ribs 17 are provided on the inner surface of the cover.

Reference numeral 18 denotes an operation component mounting plate for mounting the operation section component 21 (FIG. 2). The operation component mounting plate 18 has mounting holes for attaching the components of the operation section. plate 1
As can be seen from the side view of FIG. 2, the operation part component 21 is attached to the device 8 in a drip-proof structure. The operating component mounting plate 18 is fixed to the front surface of the frame body with screws 19 via a gasket 11 so as to cover the front open hole 10 of the frame body.

Reference numeral 20 denotes an external casing of the operating section, which is mounted on the front surface of the frame by covering the operating component mounting plate 18 and screwing the screw 24 into the plate boss 25. A hole 22 is formed in the external casing 20 through which the operating component 21 mounted on the operating component mounting plate 18 can protrude. Note that the shape of the external casing 20 is variously determined depending on the design at that time and is not limited. 23 is a display plate, which is connected to the external casing 20 of the operation section.
Operation component 21 attached and mounted on the outer surface of
Depending on the relationship, the necessary holes, makeup, scales, and other characters are provided.

In the present invention, as described above, the operating component is supported by the operating component mounting plate 18 and incorporated into the main body housing, and the operating component mounting plate 18 is mounted on the packing 11.
Since it is fixed to the main body casing through the , a drip-proof function is provided. Furthermore, in order to respond to the diversification of customer requirements, despite having a drip-proof structure, it is possible to respond simply by changing the operating component mounting plate 18 and display plate 23 for attaching operating component parts.
Its simple shape simplifies assembly, making it extremely cost-effective compared to conventional methods, which require the complexity of assembling each operating part of the operating section into the casing of the operating section. . In addition, since the shape of the operation unit housing eliminates the need to assemble any parts, there are fewer restrictions on the design, and since it can be covered at the final stage of manufacturing, it has the effect of reducing the possibility of scratches, etc. It also has
