Description

[Detailed Description of the Invention] (a) Technical Field of the Invention The present invention relates to a housing structure for a wireless device, and particularly to a novel housing structure for a small wireless device.

(b) Prior Art and Problems In recent years, with the development of communication equipment, various communication applications have expanded, and the devices themselves have become more dense and smaller. Among such communication devices, millimeter wave wireless devices for the purpose of short-distance data, video transmission, and audio are broadly classified into two types, fixed type and portable type, depending on usage conditions. The former fixed type requires a separate structure in which, for example, the high-frequency section is installed on the roof of a building, and other parts of the device are installed indoors near the operator. Furthermore, the latter portable type requires an integrated structure that simultaneously carries a high frequency section, an intermediate frequency section, and a power supply section, as typified by golf broadcasting.

Furthermore, since the purpose of use of such wireless devices is not fixed, there is a desire to use them as fixed type or portable type depending on the need.
However, conventional wireless devices have not been able to satisfy these requirements, and two types of devices have been created depending on the purpose. However, it goes without saying that a system that allows wireless devices to be easily changed from fixed to portable is extremely desirable for its versatility.

(c) Purpose of the invention The purpose of the invention is to provide a convenient and economical wireless device for consumers in accordance with such demands.

(d) Structure of the invention The high frequency section to which the antenna is connected is housed in a high frequency section housing independent from the main housing of the wireless device that houses other sections, and the cable connector and the high frequency section housing are attached to the main housing. The high frequency section housing and the main housing are separated by connecting the cable connector attached to the main housing with a cable, and the cable connector of the main housing and the cable connector of the high frequency section housing are removed to separate the high frequency section housing and the main housing. A small connector built into the housing and a small connector built into the high frequency part housing are connected through the mounting hole of the cable connector, and the main housing and the high frequency part housing are brought into close contact with each other through packing. , a housing structure of a wireless device characterized in that the structure is configured such that the two structures are fixedly connected by a stopper and configured such that the two separated structures or the integrated structure can be freely selected, and the following: This will be explained in detail with reference to the drawings.

(e) Embodiment of the invention Conventionally, such wireless devices have a length of 200 to 300 mm,
It is small, with a width of about 100 to 150 mm and a parabolic antenna diameter of about 300 mm, and the transmitter is even smaller than the receiver. When using a portable type with an integrated structure, the casing has a drip-proof structure and a DC power supply is used when used outdoors, whereas when used indoors, the casing does not need to be drip-proof. AC power is often used. In addition, for the fixed type with a separate structure, only the HF section has a completely waterproof structure, and the other intermediate frequency section (IF
Part) The main casing of other wireless devices does not need to be drip-proof, and if the HF section is for indoor use only, there is no need to make it drip-proof or waterproof. The power supply can be either DC or AC, and both power supplies have been used in the past, but the present invention proposes a housing structure that can be used for both portable and fixed applications.

In other words, the housing of the HF section has a completely waterproof structure.
If the main casing in which the IF section and the like are housed has a drip-proof structure, all of the usage conditions described above can be satisfied. FIG. 1 shows a structural diagram in which the casing of the wireless device according to the present invention is separated and used, and the HF part casing 2 to which the antenna 1 is connected is separated from the main casing 3 and the cable 4 and small connector are separated. This is an example in which AC power is supplied by connecting with cable connector 7 connected to terminal 8. In such a structure, as shown in the configuration example diagram shown in Fig. 2, the IF unit housings 2 of both the transmitting side and the receiving side are installed outdoors, and the images captured by the camera 5 in one building are transmitted to the other building. This is typically the case when a television 6 inside a building receives the image.

FIG. 3 shows a structural diagram in which the housing according to the present invention is integrated and used. In this case, the cable 4 and the cable connectors 7 on both sides of the cable 4 shown in FIG. In addition, packing 10 is provided on the contact surfaces of both the casings, and the two casings come into close contact with each other to form a drip-proof structure. In addition, in the separated structure in which the above-mentioned cable connector 7 is attached, the cable connector is attached to the housing plate.
It is tightened with a ring and has a waterproof structure. A representative configuration example of such an integrated structure is shown in FIG. 4, where a DC power source is used to capture and transmit an image outdoors, and to receive an image outdoors, and 11 in the figure indicates a battery.

FIG. 5 illustrates the locking connection of the catch 9,
The end of the metal fitting, which can rotate freely, fits into the receiver and presses the packing 10, making it waterproof, and can be attached and detached with a single touch.

Incidentally, depending on the transmission distance, it is necessary to replace the parabolic antenna and the horn antenna, and the screw method allows for easy replacement. In this way, replacement cable connector parts and spare antennas can be provided to accommodate various usage conditions.

(f) Effects of the invention As can be seen from the above explanation, by using the present invention, one type of casing structure is created using known parts and structures, the structure can be standardized, and costs can be reduced. Moreover, since it has a structure that can be used according to the needs of the consumer, it will greatly contribute to the development of this type of wireless device.
