Description

電力変換装置Power converter
　本発明は、入力された電力を所望の電力に変換して出力する電力変換装置に関するものである。 The present invention relates to a power converter that converts input power into desired power and outputs the power.
　この種の電力変換装置としては、入力された交流電力を直流電力に変換するコンバータ回路と、コンバータ回路で変換された直流電力を交流電力に変換するインバータ回路とを備えて構成されたものが一般的である。コンバータ回路及びインバータ回路は、本体筐体の内部に収容された回路基板に構成されており、三相の入力端子を介して商用電源等の外部電源に接続され、かつ三相の出力端子を介してモータ等の負荷に接続されている。入力端子及び出力端子は、ケーブルとのコンタクト部が本体筐体の外部に突出する状態でコネクタとして設けられており、本体筐体の外部からケーブルを接続することが可能である（例えば、特許文献１参照）。 This type of power converter generally comprises a converter circuit for converting input AC power to DC power and an inverter circuit for converting DC power converted by the converter circuit to AC power. It is The converter circuit and the inverter circuit are formed on a circuit board housed inside the main body casing, connected to an external power supply such as a commercial power supply via a three-phase input terminal, and via a three-phase output terminal. Connected to a load such as a motor. The input terminal and the output terminal are provided as connectors in a state where the contact portion with the cable protrudes to the outside of the main body casing, and it is possible to connect the cable from the outside of the main body casing (for example, 1).
　通常、入力用コネクタ及び出力用コネクタは、設置に必要となるスペースを削減するため、本体筐体の上面及び底面に設けられている。すなわち、本体筐体の上面や底面に入力用コネクタや出力用コネクタを設けた場合には、外部に突出するケーブルとのコンタクト部が本体筐体の投影域内に配置されるため、周囲に大きなスペースを確保することなく電力変換装置の設置が可能となる。 Usually, the input connector and the output connector are provided on the top and bottom surfaces of the main housing in order to reduce the space required for installation. That is, when the input connector and the output connector are provided on the upper surface and the bottom surface of the main body case, the contact portion with the cable protruding to the outside is arranged in the projection area of the main body case, so a large space around It is possible to install the power converter without securing the

　ところで、上述した電力変換装置には、出力用コネクタの追加設定が要望されている。例えば、エレベータ装置において昇降箱を昇降駆動する同期モータに交流電力を出力する電力変換装置では、出力端子を短絡させることで同期モータに制動を加え、昇降箱の移動速度を制御しようというものがある。このような電力変換装置にあっては、同期モータに接続される出力用コネクタとは別に補助出力用コネクタを追加設定すれば、出力用コネクタに同期モータを接続した状態であっても、追加した補助出力用コネクタにスイッチ手段を容易に接続することができるようになる。 By the way, additional setting of the connector for output is demanded to the power converter mentioned above. For example, in an electric power conversion apparatus that outputs AC power to a synchronous motor that drives an elevator box up and down in an elevator system, there is a system that applies a brake to the synchronous motor by shorting an output terminal to control moving speed of the elevator box. . In such a power conversion device, if an auxiliary output connector is additionally set apart from the output connector connected to the synchronous motor, the addition is made even if the synchronous motor is connected to the output connector. The switch means can be easily connected to the auxiliary output connector.
　ここで、本体筐体の上面及び底面には、既に入力用コネクタや出力用コネクタが設けられているため、新たに出力用コネクタを設けるためのスペースを確保することが困難である。また、本体筐体の前面や側面といった周面に出力用コネクタを設けた場合には、上述したように、突出する出力用コネクタとの干渉を避けるために周囲にスペースを確保しなければならず、設置場所に大きな制限が加えられることになる。 Here, since the input connector and the output connector are already provided on the upper surface and the bottom surface of the main body case, it is difficult to secure a space for newly providing the output connector. In addition, when the output connector is provided on the circumferential surface such as the front or side of the main housing, as described above, a space must be secured around the output connector to avoid interference with the protruding output connector. There will be major restrictions on the installation location.
　本発明は、上記実情に鑑みて、設置場所に大きな制限を加えることなく出力用コネクタを追加設定することのできる電力変換装置を提供することを目的とする。 An object of this invention is to provide the power converter device which can additionally set the connector for an output, without adding a big restriction | limiting in an installation place in view of the said situation.

A mounting portion of an input connector provided on the bottom or top surface for inputting power to the power conversion circuit, a mounting portion of an output connector for outputting power converted by the power conversion circuit, and the outside of the main body casing And a mounting portion of an auxiliary connector connected to the power conversion circuit, wherein the hollow portion is formed on the peripheral surface of the main body casing, and the auxiliary surface is formed on the inner bottom surface of the hollow portion. A mounting portion of the connector is provided.
　また本発明は、上述した電力変換装置において、実装面が前記本体筐体の前面に平行となる姿勢で配線基板を前記本体筐体の内部に配設するとともに、前記窪み部を前記本体筐体の前面に形成し、前記配線基板の前面には、前記本体筐体の窪み部に対応する部位に前記補助コネクタの実装部を配設したことを特徴とする。 Further, according to the present invention, in the power conversion device described above, the wiring board is disposed inside the main body housing in a posture in which the mounting surface is parallel to the front surface of the main body housing, and the recessed portion is the main body housing. The mounting portion of the auxiliary connector is disposed on the front surface of the wiring substrate at a portion corresponding to the depressed portion of the main body case.
　また本発明は、上述した電力変換装置において、前記配線基板を両面実装型とし、前記配線基板の後面には、前記入力用コネクタの実装部または前記出力用コネクタの実装部を配設したことを特徴とする。 Further, according to the present invention, in the power converter described above, the wiring board is a double-sided mounting type, and a mounting portion of the input connector or a mounting portion of the output connector is disposed on the back surface of the wiring board. It features.
　また本発明は、上述した電力変換装置において、前記補助コネクタは、前記出力用コネクタと並列に接続された補助出力用コネクタであり、前記出力用コネクタの実装部を前記配線基板の後面に配設したことを特徴とする。 Further, according to the present invention, in the power converter described above, the auxiliary connector is an auxiliary output connector connected in parallel with the output connector, and the mounting portion of the output connector is disposed on the rear surface of the wiring board It is characterized by having done.
　また本発明は、上述した電力変換装置において、前記補助コネクタの実装部と前記出力用コネクタの実装部とを、前記配線基板の両面の対応する位置に配設したことを特徴とする。 Further, according to the present invention, in the above-described power conversion device, the mounting portion of the auxiliary connector and the mounting portion of the output connector are disposed at corresponding positions on both sides of the wiring board.
　また本発明は、上述した電力変換装置において、前記補助コネクタをストレート方式のコネクタとし、前記出力用コネクタをライトアングル方式のコネクタとしたことを特徴とする。 Further, according to the present invention, in the above-described power conversion device, the auxiliary connector is a straight connector, and the output connector is a right angle connector.

　本発明によれば、本体筐体の前面や側面といった周面に窪み部を形成し、この窪み部の内底面から外部に突出する状態で補助コネクタを配設するようにしているため、本体筐体の周面からの補助コネクタの突出量が窪み部の高さ分だけ小さくなる。これにより、周囲にスペースを確保することなく補助コネクタを追加設定した電力変換装置を設置することが可能となる。 According to the present invention, the recessed portion is formed on the peripheral surface such as the front surface or the side surface of the main body housing, and the auxiliary connector is disposed in a state of projecting outward from the inner bottom surface of the recessed portion. The amount of protrusion of the auxiliary connector from the circumferential surface of the body is reduced by the height of the recess. Thereby, it becomes possible to install the power converter which added and set up the auxiliary connector, without securing space around.

The output connector 32 and the auxiliary output connector 33 are both mounted on a portion of the wiring board 30 corresponding to the lower right corner of the main housing 10 when the main housing 10 is viewed from the front. Therefore, it is possible to shorten the total extension of the connection wiring patterns provided from the inverter circuit 2 to the output connector 32 and the auxiliary output connector 33.
　図１及び図２に示すように、出力用コネクタ３２のコンタクト部３２ｂが突出する本体筐体１０の底面１０ｃは、ほぼ平坦状に形成してある。これに対して補助出力用コネクタ３３のコンタクト部３３ｂが突出する本体筐体１０の前面１０ａには、正面向かって右側となる縁部分に窪み部１１が設けてある。窪み部１１は、図１及び図３に示すように、その内底面１１ａが本体筐体１０の前面１０ａに対して後面１０ｂ側に一段低くなるように構成したもので、本体筐体１０の上方、下方及び右側方にそれぞれ開口するように設けてある。本実施の形態では、補助出力用コネクタ３３の実装部３３ａにコンタクト部３３ｂを接続した場合に、窪み部１１の内底面１１ａからコンタクト部３３ｂの突出端までの距離よりも大きな高さを有するように窪み部１１が設けてある。より具体的には、図３に示すように、窪み部１１の内底面から本体筐体１０の前面１０ａまでの高さは、補助出力用コネクタ３３の実装部３３ａにケーブルＣが接続されたコンタクト部３３ｂを装着し、ケーブルＣを窪み部１１において上下方向に沿って配置した場合、あるいは右方向に曲げて配置した場合に、ケーブルＣが本体筐体１０の前面１０ａより突出しないような高さとしてある。 As shown in FIGS. 1 and 2, the bottom surface 10c of the main housing 10 from which the contact portion 32b of the output connector 32 protrudes is formed substantially flat. On the other hand, in the front face 10a of the main body case 10 from which the contact part 33b of the auxiliary output connector 33 protrudes, a recessed part 11 is provided at the edge part on the right side facing the front. The recess 11 is configured such that the inner bottom surface 11a is lower than the front surface 10a of the main housing 10 by one step toward the rear surface 10b as shown in FIGS. , And are provided so as to open downward and to the right, respectively. In the present embodiment, when the contact portion 33b is connected to the mounting portion 33a of the auxiliary output connector 33, the height is greater than the distance from the inner bottom surface 11a of the recess 11 to the projecting end of the contact portion 33b. The recess 11 is provided in the More specifically, as shown in FIG. 3, the height from the inner bottom surface of the recess 11 to the front surface 10 a of the main housing 10 is a contact in which the cable C is connected to the mounting portion 33 a of the auxiliary output connector 33 The height of the cable C does not protrude from the front surface 10 a of the main housing 10 when the portion 33 b is attached and the cable C is arranged along the vertical direction in the recess 11 or bent rightward. As.
　尚、図には明示していないが、入力用コネクタ３１は、本体筐体１０の上面からコンタクト部が突出するように設けてある。また、図１中の符号４０は、本体筐体１０の後面１０ｂに設けた冷却ユニットである。冷却ユニット４０は、ＩＧＢＴやコンデンサ等の発熱モジュール（半導体素子）を冷却するためのものである。 Although not shown in the drawing, the input connector 31 is provided so that the contact portion protrudes from the upper surface of the main body case 10. Further, reference numeral 40 in FIG. 1 denotes a cooling unit provided on the rear surface 10 b of the main housing 10. The cooling unit 40 is for cooling a heat generating module (semiconductor element) such as an IGBT or a capacitor.
　上記のように構成した電力変換装置では、出力用コネクタ３２に対して独立した位置に補助出力用コネクタ３３が設けてあるため、図４に示すように、出力用コネクタ３２に同期モータＭのケーブルＣを接続した状態であっても、補助出力用コネクタ３３のそれぞれの出力端子に対してスイッチ手段ＳのケーブルＣを容易に接続することができる。これにより、出力端子を短絡させることで同期モータＭに制動を加え、昇降箱の移動速度を制御することが可能となる。 In the power converter configured as described above, since the auxiliary output connector 33 is provided at an independent position with respect to the output connector 32, as shown in FIG. Even in the state where C is connected, the cables C of the switch means S can be easily connected to the respective output terminals of the auxiliary output connector 33. As a result, the synchronous motor M can be braked by shorting the output terminal, and the moving speed of the elevator box can be controlled.
　しかも、本体筐体１０の上面に入力用コネクタ３１を配設するとともに、本体筐体１０の底面１０ｃに出力用コネクタ３２を配設しているため、入力用コネクタ３１のコンタクト部及び出力用コネクタ３２のコンタクト部３２ｂやこれらに接続したケーブルＣが本体筐体１０の前方や側方といった周囲に突出することがない。さらに、補助出力用コネクタ３３についても、本体筐体１０の前面１０ａに設けた窪み部１１の内底面１１ａから外部に突出するようにしているため、図３に示すように、コンタクト部３３ｂや接続したケーブルＣが本体筐体１０の周囲に突出することがない。これらの結果、周囲にスペースを確保することなく補助出力用コネクタ３３を追加設定した電力変換装置を設置することが可能となる。 Moreover, since the input connector 31 is disposed on the upper surface of the main body case 10 and the output connector 32 is disposed on the bottom surface 10 c of the main body case 10, the contact portion of the input connector 31 and the output connector The 32 contact portions 32 b and the cable C connected to them do not protrude around the front or side of the main body case 10. Furthermore, since the auxiliary output connector 33 is also projected to the outside from the inner bottom surface 11a of the recess 11 provided on the front surface 10a of the main body case 10, as shown in FIG. The cable C does not protrude around the main housing 10. As a result of these, it becomes possible to install a power conversion device in which the auxiliary output connector 33 is additionally set without securing a space around it.
　尚、上述した実施の形態では、配線基板３０の後面３０ｂに出力用コネクタ３２を実装する一方、配線基板３０の前面３０ａに補助出力用コネクタ３３を実装するようにしているため、それぞれの実装部３２ａ，３３ａからインバータ回路２までの間に設ける配線パターンの長さを大幅に削減することができ、配線基板３０及び本体筐体１０の小型化を図ることが可能である。しかしながら、配線基板３０に対する出力用コネクタ３２及び補助出力用コネクタ３３の実装形態は、実施の形態のものに限らない。 In the embodiment described above, the output connector 32 is mounted on the back surface 30b of the wiring substrate 30, while the auxiliary output connector 33 is mounted on the front surface 30a of the wiring substrate 30, so that the respective mounting portions The length of the wiring pattern provided between 32a and 33a and the inverter circuit 2 can be significantly reduced, and the wiring substrate 30 and the main housing 10 can be miniaturized. However, the mounting form of the output connector 32 and the auxiliary output connector 33 with respect to the wiring board 30 is not limited to that of the embodiment.
　また、上述した実施の形態では、本体筐体１０の前面１０ａに窪み部１１及び補助出力用コネクタ３３を設けるようにしているが、本体筐体１０の側面に窪み部１１を設け、この窪み部１１の内底面１１ａに補助出力用コネクタ３３を配設するように構成しても良い。尚、本体筐体１０の周面に設ける窪み部１１としては、必ずしも上端から下端にわたる部位の全長に設ける必要はなく、補助出力用コネクタ３３を配設することのできる大きさがあれば良い。 In the embodiment described above, the recessed portion 11 and the auxiliary output connector 33 are provided on the front surface 10a of the main body housing 10. However, the recessed portion 11 is provided on the side surface of the main body housing 10 The auxiliary output connector 33 may be disposed on the inner bottom surface 11 a of the reference numeral 11. The recess 11 provided on the peripheral surface of the main housing 10 does not necessarily have to be provided over the entire length of the portion extending from the upper end to the lower end, as long as the auxiliary output connector 33 can be disposed.
　さらに、上述した実施の形態では、補助出力用コネクタ３３に出力端子を短絡するためのスイッチ手段Ｓを接続するようにしているが、補助出力用コネクタ３３の用途はこれに限らない。 Furthermore, in the embodiment described above, the switch means S for shorting the output terminal is connected to the auxiliary output connector 33, but the application of the auxiliary output connector 33 is not limited to this.
　また、上述した実施の形態では、出力用コネクタ３２に並列接続される補助出力用コネクタ３３を対象としているが、入力用コネクタ３１に並列接続される入力用の補助コネクタを対象としても良いし、電力変換装置の直流中間回路に設けられる直流用の補助コネクタを対象としても構わない。 Further, in the embodiment described above, the auxiliary output connector 33 connected in parallel to the output connector 32 is targeted, but an input auxiliary connector connected in parallel to the input connector 31 may be targeted. The auxiliary connector for direct current provided in the direct current intermediate circuit of the power conversion device may be a target.
