Description

本発明は空気調和機の室外ユニットに関するものであり、機器を運転制御し駆動させる電装部品箱に電源供給や通信等を行なう電源接続ケーブルで外部より受けて中継接続するターミナル（端子台）とその固定部の取付けと、水分や塵埃からの保護構造に関するものである。   TECHNICAL FIELD The present invention relates to an outdoor unit of an air conditioner, and a terminal (terminal block) that is externally received and relayed by a power connection cable that performs power supply, communication, etc., to an electrical component box that controls and drives the equipment. The present invention relates to a fixing structure and a protection structure from moisture and dust.

従来、この種の機器の運転制御し駆動させる電装部品箱に電源供給や通信等を行なう電源接続ケーブルで外部より受けて中継接続するターミナル等は制御用電源の電装部品箱に設けている（例えば、特許文献１参照）。 Conventionally, a terminal or the like that is externally received and connected via a power connection cable for power supply or communication to an electrical component box that controls and drives this type of device is provided in the electrical component box of the control power source (for example, , See Patent Document 1).

図７は特許文献１に記載された従来の電源接続コードを中継する構造を示すものである。図７に示すように機器本体１とその内部の電装部品箱５と、ケーブル保護具７と、端子カバー部７ａと、保護部７ｂと、クランプ部７ｃとから構成されている。
特開平９―２８７７７７号公報 FIG. 7 shows a structure for relaying the conventional power connection cord described in Patent Document 1. In FIG. As shown in FIG. 7, it is comprised from the apparatus main body 1, the electrical component box 5 of the inside, the cable protector 7, the terminal cover part 7a, the protection part 7b, and the clamp part 7c.
JP-A-9-287777

しかしながら、前記従来の構成では中継接続ターミナルを電装部品箱の側面に直接固定するか、その他の構成部品にてその場所を確保することで上記のような構成をなしていた。   However, in the above-described conventional configuration, the relay connection terminal is directly fixed to the side surface of the electrical component box, or the location is secured by other component parts, so that the above configuration is achieved.

このような構成であると、中継接続するターミナルが、電装部品箱内や近傍であり、電気工事作業者が、ターミナル接続部に工事スペースが少なくなり、ターミナルのケーブル接続状態が見え難いことからこの作業性を悪化させる懸念があり、また、ターミナル取付面が地面に対し鉛直となっており、専ら下方からターミナルの接続部へケーブルを差し込み接続するため、接続が確実にされない場合があり、それによって、接続の機械的接触状態が不安定になり、大きな消費電力を必要とする場合は、中継ターミナル内部の接続部の温度が上昇し、最悪の場合、温度過昇を招く可能性があった。   In such a configuration, the terminal for relay connection is in or near the electrical component box, so that the electric construction worker has less work space in the terminal connection part and it is difficult to see the cable connection state of the terminal. There is a concern that the workability may deteriorate, and the terminal mounting surface is perpendicular to the ground, and the cable is inserted and connected exclusively from below to the terminal connection, so the connection may not be ensured. When the mechanical contact state of the connection becomes unstable and a large amount of power is required, the temperature of the connection part inside the relay terminal rises, and in the worst case, the temperature may increase.

また、保護カバーと筐体との隙間から水分や塵埃が侵入する可能性があり、前記水分や塵埃がターミナルに付着して温度過昇等の不具合を生じさせる可能性があった。   In addition, moisture and dust may enter from the gap between the protective cover and the housing, and the moisture and dust may adhere to the terminal and cause problems such as overheating.

前記従来の課題を解決するために、本発明は、電源供給あるいは通信を行なうケーブルを接続するターミナルを筐体側面部の開口部内に設けた固定部に設け、前記固定部を筐体側面と連続し斜め上方に傾斜した板状の舌部に設け、且つ前記開口部を覆う保護カバーの周縁部及び前記開口部の周縁部に複数の段状部を持たせたもので、この構成を成すことにより、ターミナルへのケーブル接続の作業性を向上させ、且つ水分や塵埃の付着からターミナル部を保護するものである。   In order to solve the above-mentioned conventional problems, the present invention provides a terminal for connecting a cable for power supply or communication in a fixed portion provided in an opening of a side surface of the housing, and the fixed portion is continuous with the side of the housing. And provided on a plate-like tongue inclined obliquely upward, and having a plurality of stepped portions at the peripheral edge of the protective cover covering the opening and the peripheral edge of the opening. Thus, the workability of connecting the cable to the terminal is improved, and the terminal portion is protected from the adhesion of moisture and dust.

本発明の空気調和機の室外ユニットは、ターミナルへのケーブル接続の作業性を向上させ、且つ水分や塵埃の付着からターミナル部を保護するものである。   The outdoor unit of the air conditioner of the present invention improves the workability of cable connection to the terminal and protects the terminal portion from the adhesion of moisture and dust.

ターミナルを筐体側面部の開口部内に固定する固定部と、前記ターミナルとの間で通信する電装部と、前記開口部を覆う保護カバーを持つ空気調和機の室外ユニットにおいて、前記固定部を筐体側面と連続し斜め上方に傾斜した板状の舌部に設け、且つ前記保護カバーの周縁部及び前記開口部の周縁部は複数の段状部を持つもので、この構成を成すことにより、ターミナル部を傾斜させケーブル線の接続作業を容易にする事が出来る。 According to a first aspect of the present invention, there is provided a terminal for connecting a cable for power supply or communication, a fixing portion for fixing the terminal in an opening of a side surface of a housing, an electrical component for communication with the terminal, and the opening In the outdoor unit of an air conditioner having a protective cover that covers the portion, the fixing portion is provided on a plate-like tongue portion that is continuous with the side surface of the casing and inclined obliquely upward, and the peripheral portion of the protective cover and the opening portion The peripheral portion has a plurality of stepped portions, and this configuration makes it possible to incline the terminal portion and facilitate the cable wire connection work.

第２の発明は、特に、第１の発明の舌部の両側部に三角壁を設けたもので、側壁を一体形成させることで、ターミナル固定部の強度とその保持力が向上できる。
第３の発明は、特に、第１および第２の発明の舌部の一部と筐体とを連結する連結桟を設けたもので、この構成を成すことにより、ターミナル固定部の強度がさらに向上し、その保持力が改善できる。
第４の発明は、特に第３の発明の連結桟の一部に開口部を設け、ターミナルと電装部との間のリード線を通したもので、この構成を成す事により、リード線を筐体部のエッジ部等に当接したり挟むことがなく、機器の安全性が向上改善できる。 In the second invention, in particular, triangular walls are provided on both side portions of the tongue portion of the first invention. By integrally forming the side walls, the strength of the terminal fixing portion and its holding force can be improved.
In the third invention, in particular, a connecting bar for connecting a part of the tongue of the first and second inventions and the housing is provided, and this configuration further increases the strength of the terminal fixing portion. It can be improved and its holding power can be improved.
In the fourth invention, an opening is provided in a part of the connecting bar of the third invention, and a lead wire is passed between the terminal and the electrical component. By configuring this structure, the lead wire is enclosed. The safety of the device can be improved and improved without being brought into contact with or sandwiching the edge of the body.
