【考案の詳細な説明】 〔産業上の利用分野〕 本考案は通信用送受信装置を一体的に備えた小型アンテ
ナ装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a small antenna device integrally provided with a transceiver for communication.
従来、この種の小型アンテナは、第３図のように主反射
鏡１に一体化されたフレーム２の先端部に送受信装置3A
を取付けており、この送受信装置3Aから主反射鏡１に向

置７と対を成しており、両者をケーブル４で接続してい
る。Conventionally, a small antenna of this type has a transmitting / receiving device 3A at the tip of a frame 2 integrated with a main reflecting mirror 1 as shown in FIG.
Is attached to and receives radio waves from the transmitting / receiving device 3A toward the main reflecting mirror 1. The transmitter / receiver 3A forms a pair with the indoor unit 7 and connects them with a cable 4.
ところで、この種の小型アンテナは、その配設位置が屋

ける適正な電圧を保持できなくなる点が問題となってい
る。By the way, when the arrangement position of this type of small antenna is different, such as on a rooftop, a garden, or a different number of stages in a building, the length of the cable 4 is also changed accordingly, which causes the voltage of the cable itself. The amount of descent is also different. Therefore, there is a problem in that an appropriate voltage cannot be maintained in the transmitter / receiver 3A depending on the installation condition of the small antenna.
そこで、従来では、屋内装置７から出力される電圧は、
前もって最悪条件を考慮した最大長さのケーブル４の電
圧降下分を加えたものとし、送受信装置3A内に設けた電
圧安定器で、使用する適正電圧に降下させ電圧の安定化
を図る構成がとられている。Therefore, conventionally, the voltage output from the indoor device 7 is
It is assumed that the voltage drop of the maximum length cable 4 is added in consideration of the worst condition in advance, and the voltage stabilizer provided in the transmitter / receiver 3A lowers the voltage to an appropriate voltage to be used to stabilize the voltage. Has been.
しかしながら、このように送受信装置3A内に電圧安定器
を内蔵させると、電圧を降下させる際に生じる熱のた
め、送受信装置3Aのケーブル内部温度が上昇し，電気・
電子部品の性能を悪化させ装置の信頼性を下げてしま
う。However, when the voltage stabilizer is built in the transmitter / receiver 3A in this way, the temperature inside the cable of the transmitter / receiver 3A rises due to the heat generated when the voltage drops, and
It deteriorates the performance of electronic parts and lowers the reliability of the device.
また、その温度上昇を抑制する構成を採用したときに
は、ケース全体が大きくなって重量が増加し、送受信装
置3Aを支持するフレーム２の強度増加のためのコストが
増大するという問題がある。Further, when the structure for suppressing the temperature rise is adopted, there is a problem that the entire case becomes large and the weight increases, and the cost for increasing the strength of the frame 2 supporting the transmitting / receiving device 3A increases.
本考案の目的は送受信装置における内部温度上昇や、そ
の大型化，コスト高を防止した小型アンテナ装置を提供
することにある。An object of the present invention is to provide a small antenna device which prevents an internal temperature rise in a transmitter / receiver device, its size and cost.
本考案の小型アンテナ装置は、送受信装置の電圧を安定
化する電圧安定器を該送受信装置とは別体に設け、この
電圧安定器を送受信装置とケーブルで電気接続した上
で、アンテナ装置の主反射鏡またはそのフレーム一部に
支持している。The small antenna device of the present invention is provided with a voltage stabilizer for stabilizing the voltage of the transmitter / receiver separately from the transmitter / receiver, and the voltage stabilizer is electrically connected to the transmitter / receiver by a cable, and then the main antenna device It is supported by the reflector or part of its frame.
この構成によれば、電圧降下時に電圧安定器に発生した
熱が送受信装置内部の温度を上昇させることはなく、送
受信装置の小型化を図る一方で、フレーム強度の増大を
不要とする。According to this configuration, the heat generated in the voltage stabilizer at the time of voltage drop does not raise the temperature inside the transmitter / receiver, and the transmitter / receiver can be downsized while the increase in frame strength is unnecessary.
次に、本考案を図面を参照して説明する。 Next, the present invention will be described with reference to the drawings.
第１図は本考案の一実施例の側面図である。図におい

用ステム等に固定されている。FIG. 1 is a side view of an embodiment of the present invention. In the figure, reference numeral 1 denotes a main reflecting mirror, and a transmitting / receiving device 3 is fixed to a tip portion of a frame 2 integrated with the main reflecting mirror 1.
As shown in the enlarged view of FIG.
It has two input and output ends, and cables 4 and 5 are connected to each. One cable 4 is connected to an indoor device (not shown). Further, a voltage stabilizer 6 for maintaining the voltage of the transmitter / receiver 3 at an appropriate voltage is connected to the other cable 5. The voltage stabilizer 6 is fixed to the supporting stem of the main reflecting mirror 1 or the like.

号は、ケーブル４を経由して一旦送受信装置３に入り、
電源だけはケーブル５を通り電圧安定器６に入る。そこ

装置３に入る。According to this configuration, the power and signal supplied from the indoor device once enter the transmitting / receiving device 3 via the cable 4,
Only the power supply passes through the cable 5 and enters the voltage stabilizer 6. Then, the voltage is dropped to an appropriate voltage, and the signal passes through the cable 5 and enters the transmitter / receiver 3 again.
したがって、電圧降下時には電圧安定器６において熱が
発生し、この熱は電圧安定器のケースから放熱される。

くする必要もなく、かつフレーム２の強度を高める必要
もなく、小型化，低コスト化が可能となる。Therefore, when the voltage drops, heat is generated in the voltage stabilizer 6, and this heat is radiated from the case of the voltage stabilizer.
In this case, since the voltage stabilizer 6 is separated from the transmitter / receiver 3, the temperature inside the transmitter / receiver 3 does not rise. As a result, it is not necessary to increase the size of the transmitting / receiving device 3 and the strength of the frame 2, and it is possible to reduce the size and cost.

ことができる効果がある。As described above, according to the present invention, the voltage stabilizer is provided separately from the transmitter / receiver, and the voltage stabilizer is electrically connected to the transmitter / receiver by a cable and then supported by the antenna device. The heat generated in the voltage stabilizer does not raise the temperature inside the transceiver. As a result, there is no need to increase the size of the transmitter / receiver for heat dissipation, and it is not necessary to increase the frame strength accordingly, and it is possible to reduce the size of the transmitter / receiver and the cost of the small antenna. is there.
