Abstract

Outdoor radio equipment includes a radio transmitting and receiving part for performing a modulation and demodulation process, and a common part for controlling an action of the radio transmitting and receiving part. The radio transmitting and receiving part is provided at the common part so as to be exposed to open air.

Claims

1. Outdoor radio equipment, comprising:

a radio transmitting and receiving part for performing a modulation and demodulation process; and

a common part for controlling an action of the radio transmitting and receiving part, wherein

the radio transmitting and receiving part is provided at the common part so as to be exposed to open air, and

at least a part of an external side surface of the radio transmitting and receiving part is exposed to open air.

2. The outdoor radio equipment as claimed in claim 1,

wherein a plurality of the radio transmitting and receiving part is provided at the common part.

3. The outdoor radio equipment as claimed in claim 1,

wherein the common part includes a first interface part for the transmitting and receiving part including a first connector,

the radio transmitting and receiving part includes a second interface part for the common part including a second connector,

the second interface part is provided at a side, where the common part is provided, of the radio transmitting and receiving part, and

the radio transmitting and receiving part is electrically connected to the common part by engaging the second connector of the second interface part with the first connector of the first interface part.

4. The outdoor radio equipment as claimed in claim 3,

wherein at least one of the second connector of the second interface part and the first connector of the first interface part is floatably supported in an installation surface.

5. The outdoor radio equipment as claimed in claim 3,

wherein a waterproof member is provided at a surface where the second interface part of the radio transmitting and receiving part comes in contact with the first interface part of the common part.

6. The outdoor radio equipment as claimed in claim 3,

wherein the radio transmitting and receiving part includes a shaft member,

the shaft member is provided at an upper part of the side where the radio transmitting and receiving part is installed to the common part,

the common part includes a bearing part,

the bearing part is provided at an upper pan of the side where the common part is installed to the radio transmitting and receiving part, and

the shaft member is hung in the bearing part and rotated, so that the radio transmitting and receiving part is connected to the common part.

7. The outdoor radio equipment as claimed in claim 1, wherein

the radio transmitting and receiving part includes a housing,

electrical equipment is provided inside of the housing of the radio transmitting and receiving part,

a radiation heat member is provided at a side to be installed to the common part, of the housing of the radio transmitting and receiving part,

the electrical equipment comes in contact with the housing or the radiation beat member directly or indirectly, and

the heat from the electrical equipment is transferred to open air via the housing or the radiation heat member.

8. The outdoor radio equipment as claimed in claim 7,

wherein a gap is formed between the radiation heat member provided at the housing part and the common part when the radio transmitting and receiving part is installed to the common part.

9. The outdoor radio equipment as claimed in claim 7,

wherein the electronic equipment provided at the housing of the radio transmitting and receiving part includes:

an electric power source part for supplying an electric power to electronic components provided at the radio transmitting and receiving part,

a microwave transmitting part for converting information to a signal to be transmitted, a microwave receiving pan for converting a received signal to information; and

a modulation and demodulation part for modulating and demodulating a signal wave.

10. The outdoor radio equipment as claimed in claim 1,

wherein the common part includes:

an electric power source part for converting a first electric power source to a second electric power source and supplying electric power to electronic components provided at the common part,

a control part for monitoring the radio transmitting and receiving part installed to the common part, and controlling a branching part for selecting a signal and distributing the signal to the radio transmitting and receiving part, and

a switching part for switching one of a plurality of the radio transmitting and receiving parts installed to the common part.

11. A radio unit, the radio unit being installed to a common part which has a function of transmitting and receiving a radio signal via an antenna and a substantially box-type configuration,

the radio unit having a modulation and demodulation part for performing a demodulation process of an input radio signal of the common part, outputting the demodulated signal to the common part, performing a modulation process by using another radio signal input from the common part, and outputting a modulated wave to the common part,

the radio unit, comprising:

a second connector part which is engaged with a first connector part of a side surface of the common part when the modulation and demodulation part is installed to the common part and which transmits and receives a signal including the radio signal,
