Description

本発明は、電気機器の動作情報を外部と通信する機能を備えたキャビネットに関する。   The present invention relates to a cabinet having a function of communicating operation information of electrical equipment with the outside.

従来、電気機器の動作情報を無線で外部と通信するために、送受信ユニットを筺体の内側に設置したキャビネットが知られている。この種のキャビネットは、電気機器や送受信ユニットを含む内機を保護できるように筺体が金属製であるため、電波が筺体により遮蔽され、通信に支障を来たすことがある。そこで、電波を中継する空中線を筺体上に装備したキャビネットが提案されている。   2. Description of the Related Art Conventionally, a cabinet in which a transmission / reception unit is installed inside a housing is known in order to wirelessly communicate operation information of electrical equipment with the outside. In this type of cabinet, since the housing is made of metal so that the internal unit including the electric equipment and the transmission / reception unit can be protected, radio waves may be shielded by the housing, which may hinder communication. Therefore, a cabinet equipped with an antenna for relaying radio waves on the housing has been proposed.

例えば、特許文献１には、開口部を備えた一対の筺体の間に絶縁材料からなるパッキンを介装し、パッキンに空中線を装着する技術が提案されている。ここでは、図７に示すように、パッキン５１が２枚のパッキン部品５２，５３の間にプリント配線板５４を備え、この配線板５４上に空中線（Ｌ型ダイポールアンテナ）５５が装着されている。   For example, Patent Document 1 proposes a technique in which a packing made of an insulating material is interposed between a pair of housings having openings, and an antenna is attached to the packing. Here, as shown in FIG. 7, the packing 51 includes a printed wiring board 54 between two packing parts 52 and 53, and an antenna (L-shaped dipole antenna) 55 is mounted on the wiring board 54. .

ところが、従来のキャビネットによると、筺体に空中線を設けるために、２つのパッキン部品５２，５３とプリント配線板５４が必要になり、部品点数と組立工数が増えるという不都合があった。また、筺体に大きな面積の開口部を加工する必要があり、筺体の剛性が低下し、キャビネット本来の機器保護機能に悪影響を及ぼすという問題点もあった。   However, according to the conventional cabinet, two packing parts 52 and 53 and a printed wiring board 54 are required to provide an aerial wire in the housing, resulting in an increase in the number of parts and the number of assembly steps. In addition, it is necessary to process a large-area opening in the casing, which causes a problem that the rigidity of the casing is lowered and adversely affects the original equipment protection function of the cabinet.

本発明の目的は、筺体の剛性を低下させることなく、空中線を簡易に装着できるキャビネットを提供することにある。   The objective of this invention is providing the cabinet which can mount | wear an aerial wire simply, without reducing the rigidity of a housing.
