Description

  The present invention relates to an electronic apparatus such as a DVOR (Doppler VHF Omnidirectional Radio Range) device used in, for example, a radio navigation facility.

  In general, DVOR devices are known to be used to provide aircraft with orientation information from a reference point magnetic north. Such a DVOR device includes a carrier antenna and a plurality of, for example, 48 sideband antennas arranged in a circle around the carrier antenna, and a fixed phase RF (Radio) regardless of the direction from the carrier antenna. Frequency) signal is radiated, and an RF signal whose phase changes depending on the direction is radiated from the sideband antenna.

  On the other hand, an aircraft using a radio navigation facility is equipped with a receiver. By receiving and comparing the two signals from the DVOR device with this receiver, the receiver receives the signal from the DVOR device as a reference point at the reception point. You can know the direction. At this time, the DVOR device switches the output timing of the RF signal from the sideband antenna at the distributor of the sideband transmitter, and outputs the RF signal to the sideband antenna via the coaxial connector. (See, for example, Patent Document 1).

  By the way, in such a DVOR device, for example, 52 coaxial connectors and a large number of coaxial connectors are arranged at predetermined intervals on the wall surface of the device casing. The 52 coaxial connectors are electrically connected to an internal device such as a transmitter accommodated in the device casing.

  However, in the above-described DVOR device, a coaxial cable having an allowable bending radius for a large number of 52 coaxial connectors is connected to each other, so that a space for bending the coaxial cable is secured when the equipment casing is installed and arranged. Therefore, there is a problem that it is necessary to provide a wide installation space on the wall surface side where the coaxial connector is arranged.

  In consideration of the wiring route to the antenna of the coaxial cable, 52 coaxial connectors may be arranged on the upper surface side of the equipment housing to eliminate the bending wiring of the coaxial cable. Considering this, it is necessary to increase the installation interval of the connectors, which causes a problem that the device casing is increased in size.

  Such a situation is not limited to the DVOR device, and the same applies to an electronic device such as a transceiver having a large number of coaxial connectors to which coaxial cables are wired.

  The present invention includes an apparatus housing provided with a plurality of connector mounting portions that are respectively protruded from the wall surface and arranged side by side in the vertical direction, and are disposed obliquely upward on each of the plurality of connector mounting portions. The electronic apparatus is configured with a plurality of coaxial connectors to which the coaxial cable is attached and detached.

  According to the above configuration, when the coaxial cable is attached to the coaxial connector of the connector mounting portion from the upper surface side of the device casing, the coaxial cable approaches the wall surface of the device casing along the direction of the coaxial connector. It is pulled out above the device casing through a path having a large bending radius. As a result, the coaxial cable can be wired and connected to the coaxial connector while being close to the wall surface of the equipment casing, and the coaxial cable can be easily attached to and detached from the coaxial connector. In addition, it is possible to reduce the installation space of the device casing.

  As described above, according to the present invention, it is possible to provide an electronic device that can realize a simple and easy cable attaching / detaching operation and minimizing the installation space while achieving downsizing. can do.
