しかしながら、前記従来の構成では、コントロールボックスの下板金カバーと制御基板のグランドとの接続は、制御基板をコントロールボックスへ組み込んだ後、ビス止めするため、ビス止め時に制御基板上の他の実装部品を損傷させる可能性があるという課題や、ビス止めする工程が必要となり工数がかかるという課題を有していた。   However, in the above-described conventional configuration, the lower plate metal cover of the control box and the ground of the control board are connected to the control board after the control board is assembled into the control box, and then screwed. There is a problem that there is a possibility of damaging the steel and a problem that a process of screwing is required and man-hours are required.

本発明は、前記従来の課題を解決するもので、制御基板をコントロールボックスに組み込み、コントロールボックスの蓋をすることにより制御基板のグランドとコントロールボックスの下板金カバーとが電気的に接続される空気調和機を提供することを目的とする。   The present invention solves the above-mentioned conventional problems. The control board is incorporated in the control box, and the control box ground is electrically connected to the lower sheet metal cover of the control box by covering the control box. The purpose is to provide a harmony machine.

前記従来の課題を解決するために、高圧発生器と制御基板を収納するコントロールボックスとを備え、前記高圧発生器の放熱板と前記コントロールボックスの外側に配した板金カバーとが電気的に接続されている空気調和機において、前記板金カバーの蓋側部分に金属製の接触端子を設け、前記板金カバーの蓋側部分を閉じることにより、前記接触端子が前記制御基板のグランドパターンに圧着され、前記接触端子と前記制御基板のグランドとが電気的に接続されることで、前記高圧発生器の放熱板と前記制御基板のグランドとが電気的に接続される構成とすることで、制御基板にビス止めする工程が不要となり、制御基板に配置された実装部品の損傷を防止することができる。   In order to solve the above-described conventional problems, a high-pressure generator and a control box for storing a control board are provided, and a heat dissipation plate of the high-voltage generator and a sheet metal cover disposed outside the control box are electrically connected.

第1の発明は、高圧発生器と制御基板を収納するコントロールボックスとを備え、前記高圧発生器の放熱板と前記コントロールボックスの外側に配した板金カバーとが電気的に接続されている空気調和機において、前記板金カバーの蓋側部分に金属製の接触端子を設け、前記板金カバーの蓋側部分を閉じることにより、前記接触端子が前記制御基板のグランドパターンに圧着され、前記接触端子と前記制御基板のグランドとが電気的に接続されることで、前記高圧発生器の放熱板と前記制御基板のグランドとが電気的に接続される構成とすることで、制御基板にビス止めをする必要がないため工数をかけることなく、制御基板に配置された実装部品の損傷も防止することができる。   1st invention is equipped with the high voltage generator and the control box which accommodates a control board, The air conditioner with which the heat sink of the said high voltage generator and the sheet metal cover distribute | arranged to the outer side of the said control box are electrically connected In the machine, by providing a metal contact terminal on the lid side portion of the sheet metal cover, and closing the lid side portion of the sheet metal cover, the contact terminal is crimped to the ground pattern of the control board, and the contact terminal and the The control board ground is electrically connected, so that the heat sink of the high voltage generator and the ground of the control board are electrically connected, and it is necessary to screw the control board Therefore, the mounting components arranged on the control board can be prevented from being damaged without man-hours.

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。従来の構成と同じ部位については、同じ符号を付して説明する。   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. The same parts as those in the conventional configuration will be described with the same reference numerals.

(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1に配置されたコントロールボックス2の要部を示す断面図である。コントロールボックス2は従来例と同様、図2に示すように空気調和機1内の側部に配置されており、図3(a)に示すように、コントロールボックス2に隣接して高圧発生器3が配置されている。
(Embodiment 1)
FIG. 1 is a cross-sectional view showing a main part of a control box 2 arranged in an air conditioner 1 according to the first embodiment of the present invention. Like the conventional example, the control box 2 is disposed on the side of the air conditioner 1 as shown in FIG. 2, and the high pressure generator 3 is adjacent to the control box 2 as shown in FIG. Is arranged.

コントロールボックス2は、図1に示すように、その内部に制御基板8を配置している。樹脂製のコントロールボックス2の外側は導電性の下板金カバー5aで覆われており、両者は接着固定され一体となっている。同様に、樹脂製のコントロールボックスの蓋6の
外側も導電性の上板金カバー5bで覆われており、両者は接着固定され一体となっている。そして、下板金カバー5aの上側に、上板金カバー5bを覆いかぶせ、蓋をするように組み付け、上板金カバー5bと下板金カバー5aとはネジ(図示せず)等で接続固定している。
As shown in FIG. 1, the control box 2 has a control board 8 disposed therein. The outside of the resin control box 2 is covered with a conductive lower sheet metal cover 5a, and both are bonded and fixed together. Similarly, the outside of the lid 6 of the resin control box is also covered with a conductive upper sheet metal cover 5b, and both are bonded and fixed together. Then, the upper sheet metal cover 5b is covered on the upper side of the lower sheet metal cover 5a and assembled so as to cover it, and the upper sheet metal cover 5b and the lower sheet metal cover 5a are connected and fixed with screws (not shown) or the like.

高圧発生器3はイオンを発生させる際に高熱となり、その発生した熱を放熱するために、図3(b)に示すように、放熱板4が取り付けられている。高圧発生器3の放熱板4は、図3(b)に示すように、ビス10を用いて下板金カバー5aと接続固定されている。   As shown in FIG. 3B, the high-pressure generator 3 is attached with a heat radiating plate 4 to generate high heat when generating ions, and to radiate the generated heat. As shown in FIG. 3B, the heat radiating plate 4 of the high-pressure generator 3 is connected and fixed to the lower sheet metal cover 5 a using screws 10.

そして、上板金カバー5bの側面には、図1に示すように、コントロールボックスの蓋6を貫通した状態で、接触端子7が溶接等で固定されている。接触端子7は、銅等の導電性の材料で形成され、ばね性を持った折れ曲がった形状をしている。そして、上板金カバー5bを下板金カバー5aにかぶせたときに、接触端子7の先端面が制御基板8のグランドパターン9に圧着されるように構成している。これにより、上板金カバー5bと下板金カバー5aとを組み付けた状態では、接触端子7を介して、上板金カバー5bと制御基板8のグランドが電気的に接続される。さらに、上板金カバー5bと下板金カバー5aとは接続固定されており、下板金カバー5aは高圧発生器3の放熱板4と接続固定されているので、高圧発生器3の放熱板4は制御基板8のグランドに電気的に接続されることになる。   And as shown in FIG. 1, the contact terminal 7 is being fixed to the side surface of the upper sheet metal cover 5b by welding etc. in the state which penetrated the cover 6 of the control box. The contact terminal 7 is formed of a conductive material such as copper, and has a bent shape with a spring property. Then, when the upper sheet metal cover 5 b is placed on the lower sheet metal cover 5 a, the front end surface of the contact terminal 7 is configured to be crimped to the ground pattern 9 of the control board 8. Thereby, in the state where the upper sheet metal cover 5 b and the lower sheet metal cover 5 a are assembled, the ground of the upper sheet metal cover 5 b and the control board 8 is electrically connected via the contact terminals 7. Furthermore, since the upper sheet metal cover 5b and the lower sheet metal cover 5a are connected and fixed, and the lower sheet metal cover 5a is connected and fixed to the heat radiating plate 4 of the high voltage generator 3, the heat radiating plate 4 of the high voltage generator 3 is controlled. It is electrically connected to the ground of the substrate 8.

よって、高圧発生器3の放熱板4が、高圧発生器3より発生するイオンにより帯電されたとしても、放熱板4は上、下板金カバー5b、5aおよび接触端子7を介して制御基板8のグランドに電気的に接続されているので、放熱板4に帯電した電位を制御基板8のグランドに放電することで、制御基板8の誤動作や破壊を防止することができる。   Therefore, even if the heat radiating plate 4 of the high voltage generator 3 is charged by ions generated from the high voltage generator 3, the heat radiating plate 4 is connected to the control board 8 via the upper, lower sheet metal covers 5b, 5a and the contact terminals 7. Since it is electrically connected to the ground, it is possible to prevent malfunction and destruction of the control board 8 by discharging the potential charged to the heat sink 4 to the ground of the control board 8.

そして、上、下板金カバー5b、5aと制御基板8のグランドとの電気的接続を、ビスを用いずに、上板金カバー5bを下板金カバー5aに組み付けるだけで、接触端子7により電気的接続可能とするので、ビス止めする工程を必要とせず、工数をかけることなく作業性がよく、また、ビス止め時に制御基板上の他の実装部品を損傷させるのを防止することができる。   Then, the electrical connection between the upper and lower sheet metal covers 5b and 5a and the ground of the control board 8 is made by connecting the upper sheet metal cover 5b to the lower sheet metal cover 5a without using screws, and is electrically connected by the contact terminals 7. Therefore, it is possible to eliminate the need for a screwing step, improve workability without man-hours, and prevent other mounted parts on the control board from being damaged during screwing.

本発明は、高圧発生器を搭載した空気調和機以外の機器の用途にも適用できる。   The present invention can also be applied to applications other than air conditioners equipped with a high-pressure generator.
