Description

本発明は、各種の電気回路に用いる高電圧ジャンクションボックスに関するものである。   The present invention relates to a high voltage junction box used for various electric circuits.

例えば、自動車の電気回路用の電源回路として、高電圧、大電流を必要とする回路部品を備えた高電圧ジャンクションボックスが良く知られている。   For example, as a power supply circuit for an electric circuit of an automobile, a high voltage junction box having circuit components that require a high voltage and a large current is well known.

しかし従来の高電圧ジャンクションボックスでは、高電圧のもとに大電流を内部の電気部品に通電するために、金属板から成る複数のバスバーを使用することが多く、このバスバー同士が交叉する個所においては、互いに接触せず絶縁性を確保するために、立体的な交叉を行う必要がある。   However, the conventional high voltage junction box often uses multiple bus bars made of metal plates to pass a large current to the internal electrical components under high voltage, and the bus bars cross each other. In order to ensure insulation without contacting each other, it is necessary to perform a three-dimensional crossover.

従って、スペース空間を要することにより、高電圧ジャンクションボックスの体積が大きくなるという欠点を有している。或いは、特許文献1のようにバスバーを縦にして並列することも知られているが、この場合にも大きな空間的なスペースを必要とする。   Therefore, since the space is required, the volume of the high voltage junction box is increased. Alternatively, it is known that the bus bars are arranged in parallel as in Patent Document 1, but in this case as well, a large space is required.

本発明の目的は、このようなバスバーの立体的配線を行うことなく、バスバーを積層して平面的に配線を行い、小型化し得る高電圧ジャンクションボックスを提供することにある。   An object of the present invention is to provide a high voltage junction box that can be miniaturized by stacking bus bars and wiring in a plane without performing such three-dimensional wiring of the bus bars.

上述の目的を達成するための本発明に係る高電圧ジャンクションボックスの技術的特徴は、合成樹脂製の筐体内において、導電金属板を偏平に形成したバスバーにより高圧回路配線を構成し、前記バスバーを平面絶縁材を介して積層して回路構成したことにある。   The technical feature of the high voltage junction box according to the present invention for achieving the above object is that a high voltage circuit wiring is constituted by a bus bar in which a conductive metal plate is formed flat in a synthetic resin casing, and the bus bar is The circuit configuration is formed by laminating via a planar insulating material.

本発明に係る高電圧ジャンクションボックスによれば、導電金属板から成るバスバーを平面絶縁材を介して積層することにより、バスバーが交叉する場合においても短絡することはなく空間スペースを減少し、小型化が可能となる。   According to the high voltage junction box according to the present invention, by stacking bus bars made of conductive metal plates via a planar insulating material, even when the bus bars cross each other, there is no short circuit and the space space is reduced and the size is reduced Is possible.

These wirings are arranged in the lower layer of the upper lid 2. Yes.

図2は上蓋2を外した状態の筐体1の最下層の底面を示している。筐体1の機械的な強度を補強すると共に、通気による放熱効果を持たせるための多数のリブ1bが格子状に形成されている。筐体1の所要個所には、電気部品を固定するためのねじ孔、配線を接続するための電気端子等が設けられ、筐体1の周囲には、筐体1を例えば自動車のフレームに固定するための複数のボルト孔1cが設けられている。   FIG. 2 shows the bottom surface of the lowermost layer of the housing 1 with the upper lid 2 removed. A number of ribs 1b for reinforcing the mechanical strength of the housing 1 and providing a heat dissipation effect by ventilation are formed in a lattice shape. Screw holes for fixing electrical components, electrical terminals for connecting wirings, and the like are provided at required locations of the casing 1, and the casing 1 is fixed to, for example, a car frame around the casing 1. A plurality of bolt holes 1c are provided.

In the groove portion 14a provided on the insulating plate 14, a flat bus bar 15 made of the same metal plate is disposed for the same purpose as that of the circuit using the bus bar 11, and fixed by a pin 14b provided in the groove portion 14a. Has been. The bus bar 15 is also connected to electrical components for high voltage and large current in the same manner as the bus bar 11.

絶縁プレート14として、一般的なエンジニアリングプラスチックが使用でき、具体的にはポリブチレンテレフラレート(PBT)を用いればよく、その厚みは0.5〜3mm程度が好適である。   As the insulating plate 14, a general engineering plastic can be used. Specifically, polybutylene terephthalate (PBT) may be used, and the thickness is preferably about 0.5 to 3 mm.

そして、この絶縁プレート14、バスバー15、メインスイッチ16の上に、図1に示すように複数の電気部品を配置し、裏面において或る程度の配線が施されている上蓋2を積層し、上蓋2に固定された電気部品に、バスバー11、15、銅箔回路13の端部が、例えば上蓋2上から挿入して、筐体1の裏側に配置したナットと螺合させた導通ボルト17により接続されている。   A plurality of electrical components are arranged on the insulating plate 14, the bus bar 15, and the main switch 16 as shown in FIG. 1, and the upper lid 2 to which a certain amount of wiring is applied on the back surface is laminated. The end portions of the bus bars 11 and 15 and the copper foil circuit 13 are inserted into the electrical components fixed to 2 from, for example, the upper lid 2 and screwed with the nuts arranged on the back side of the housing 1.
