Abstract

<P>PROBLEM TO BE SOLVED: To prevent generation of a short circuit caused by damaging of coating of a lead wire caused by contact of the lead wire with a lead leg of a power module, and the generation of a short circuit caused by melting of the coating of the lead wire when the lead wire exists near the power module when the power module is broken, by separating the lead leg or the body of the power module and the lead wire by a partitioning plate. <P>SOLUTION: In this air conditioner, the partitioning plate 7 is fastened together with the power module 1 by a screw 3 connecting the power module 1 and a radiation plate 2, thus the lead leg or the body of the power module 1 is separated from the lead wire 5. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

本発明は、空気調和機のインバータ回路の構造に関するものである。 The present invention relates to the structure of an inverter circuit of an air conditioner.

従来、この種の空気調和機としては、図２に示すものがあった（特許文献１参照）。図２は従来の空気調和機を示すものであり、圧縮機モータを駆動するパワーモジュール１と、パワーモジュール１に取り付けられる放熱板２と、パワーモジュール１と放熱板２を接合させるネジ３と、パワーモジュール１が下向きかつ端面に半田付けされるプリント配線板４と、パワーモジュールとプリント基板４の端面の間に半田付けされパワーモジュール１と圧縮機モータを接続するリード線５と、プリント配線板４が収納され放熱板２が外部に露出するようにされている電源箱６とから構成されている。
特開平１０−２０５８３０号公報 Conventionally, this type of air conditioner has been shown in FIG. 2 (see Patent Document 1). FIG. 2 shows a conventional air conditioner, which includes a power module 1 that drives a compressor motor, a heat sink 2 that is attached to the power module 1, a screw 3 that joins the power module 1 and the heat sink 2, A printed wiring board 4 in which the power module 1 is soldered downward and to the end face, a lead wire 5 that is soldered between the power module and the end face of the printed board 4 and connects the power module 1 and the compressor motor, and a printed wiring board 4 and a power supply box 6 in which the heat radiating plate 2 is exposed to the outside.
Japanese Patent Laid-Open No. 10-205830

しかしながら、前記従来の構成では、リード線が電源箱とパワーモジュールと放熱板に囲まれる小さなスペースに配線されているため、リード線がパワーモジュールのリード足に接触してリード線の被覆に傷をつけてショートを発生させたり、パワーモジュールが破壊したときに近傍にリード線が存在するためにリード線の被覆がとけてショートを発生させるという危険性があった。   However, in the conventional configuration, since the lead wire is wired in a small space surrounded by the power supply box, the power module, and the heat sink, the lead wire contacts the lead leg of the power module and damages the lead wire coating. When the power module is destroyed, there is a danger that the lead wire is removed and the short circuit occurs due to the presence of the lead wire in the vicinity.

本発明は、上記従来の課題を解決することを目的とするものである。   The present invention aims to solve the above conventional problems.

前記従来の課題を解決するために、本発明の空気調和機は、パワーモジュールのリード足またはボディとリード線を隔離するために、隔離板をパワーモジュールにネジ止めするものである。   In order to solve the above-described conventional problems, the air conditioner of the present invention is configured to screw a separator to the power module in order to isolate the lead leg or body of the power module from the lead wire.

本発明の空気調和機は、隔離板をパワーモジュールと放熱板を接続しているネジによってパワーモジュールに共締めすることで、パワーモジュールのリード足またはボディとリード線を隔離させ、リード線がパワーモジュールのリード足に接触してリード線の被覆に傷をつけてショートを発生させたり、パワーモジュールが破壊したときに近傍にリード線が存在するためにリード線の被覆がとけてショートを発生させるという課題を解決するものである。   In the air conditioner of the present invention, the lead plate or the body of the power module is separated from the lead wire by fastening the separator plate to the power module together with the screw connecting the power module and the heat radiating plate, and the lead wire is powered. Touching the module's lead feet and scratching the lead wire sheath to cause a short circuit, or when the power module is destroyed, the lead wire is present in the vicinity, causing the lead wire sheath to break and causing a short circuit It solves the problem.

第１の発明は、隔離板をパワーモジュールと放熱板を接続しているネジによってパワーモジュールに共締めすることで、パワーモジュールのリード足またはボディとリード線を隔離させ、リード線がパワーモジュールのリード足に接触してリード線の被覆に傷をつけてショートを発生させたり、パワーモジュールが破壊したときに近傍にリード線が存在するためにリード線の被覆がとけてショートを発生させたりすることを防ぐことができる。   In the first aspect of the invention, the lead plate or body of the power module is separated from the lead wire by fastening the separator plate to the power module together with a screw connecting the power module and the heat radiating plate. Touching the lead foot and scratching the lead wire sheath to cause a short circuit, or when the power module breaks, the lead wire is present in the vicinity, causing the lead wire sheath to break and causing a short circuit. Can be prevented.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

（実施の形態１）
図１は本発明の第１の実施の形態における空気調和機のインバータ回路の構造である。圧縮機モータを駆動するパワーモジュール１と、パワーモジュール１に取り付けられる放熱板２と、パワーモジュール１と放熱板２を接合させるネジ３と、パワーモジュール１が下向きかつ端面に半田付けされるプリント配線板４と、パワーモジュール１とプリント配線板４の端面の間に半田付けされパワーモジュール１と圧縮機モータを接続するリード線５と、プリント配線板４が収納され放熱板２が外部に露出するようにされている電源箱６とから構成され、パワーモジュール１のプリント配線板４に接続されるリード足を取り囲む隔離板７がネジ３によってパワーモジュール１に取り付けられている。 (Embodiment 1)
FIG. 1 shows the structure of an inverter circuit of an air conditioner according to the first embodiment of the present invention. Power module 1 for driving the compressor motor, a heat sink 2 attached to the power module 1, a screw 3 for joining the power module 1 and the heat sink 2, and a printed wiring in which the power module 1 is soldered downward and on the end face The board 4, the lead wire 5 that is soldered between the power module 1 and the end face of the printed wiring board 4, and connects the power module 1 and the compressor motor, and the printed wiring board 4 are housed and the heat sink 2 is exposed to the outside. A power supply box 6 configured as described above and a separator plate 7 surrounding a lead leg connected to the printed wiring board 4 of the power module 1 is attached to the power module 1 by screws 3.

以上のように構成された空気調和機では、パワーモジュールのリード足またはボディとリード線が隔離板７によって分離されているため、リード線がパワーモジュールのリード足に接触してリード線の被覆に傷をつけてショートを発生させたり、パワーモジュールが破壊したときに近傍にリード線が存在するためにリード線の被覆がとけてショートを発生させたりすることを防ぐことができる。   In the air conditioner configured as described above, since the lead foot or body of the power module and the lead wire are separated by the separator plate 7, the lead wire contacts the lead foot of the power module and covers the lead wire. It can be prevented that a short circuit is caused by scratching, or that the lead wire is uncovered due to the presence of the lead wire in the vicinity when the power module is broken, and the short circuit is generated.

本発明の空気調和機は空気調和機のインバータ回路の構造に関するものであるが、同様の構成をもつ他のインバータ機器にも適用できる。   The air conditioner of the present invention relates to the structure of the inverter circuit of the air conditioner, but can also be applied to other inverter devices having the same configuration.
