Description

本発明はコンデンサの取付装置およびその取付方法の中で、特に長円形のコンデンサに関するものである。   The present invention relates to a capacitor mounting device and a mounting method thereof, and more particularly to an oval capacitor.

コンデンサを横にして基板に固定する方法としては、たとえば実開昭５３−８５６０号公報に記載されているように、固定バンドを使用して基板に固定する方法が行われていた。
図３に、長円形コンデンサの場合の固定する方法を示す。１はコンデンサ本体、２はこのコンデンサ本体１に設けられた外部端子、７は固定バンドで、上記コンデンサ本体１を基板６に取付けるための取付部品であり、この取付部品は上記コンデンサ本体１の上周面の略大半を締め付けるように板状の金属板を加工したであり、その取付部品の外周部に設けられた複数の取付穴５を介して取付ネジ４を締め付けることによって基板６に取付るように構成されている。
実開昭５３−８５６０号公報 As a method for fixing the capacitor sideways to the substrate, for example, as described in Japanese Utility Model Publication No. 53-8560, a method of fixing to the substrate using a fixing band has been performed.
FIG. 3 shows a fixing method in the case of an oval capacitor. 1 is a capacitor body, 2 is an external terminal provided on the capacitor body 1, 7 is a fixed band, and is an attachment part for attaching the capacitor body 1 to the substrate 6. A plate-shaped metal plate is processed so as to tighten almost the entire peripheral surface, and is attached to the substrate 6 by tightening attachment screws 4 through a plurality of attachment holes 5 provided in the outer peripheral portion of the attachment part. It is configured as follows.
Japanese Utility Model Publication No. 53-8560

従来の固定バンド構成で、耐振動性を上げようとすると、肉厚の厚いものを使用しなければならずその分だけ高さ方向に無駄なスペースが発生してしまうという課題がある。
また、固定バンドが平板で、上部から押さえ込んで左右の取付ネジで固定すると、上下・左右方向の耐震動性より前後方向の耐振動性が弱いという課題がある。 In order to increase the vibration resistance with the conventional fixed band configuration, a thicker one must be used, and there is a problem that a wasteful space is generated in the height direction.
Further, when the fixing band is a flat plate and pressed from the top and fixed with the left and right mounting screws, there is a problem that the vibration resistance in the front-rear direction is weaker than the vibration resistance in the vertical and horizontal directions.

本発明は、断面が半円もしくは半だ円部と直線部からなる長円形のコンデンサを、コンデンサ取付部品により基板表面に取付け固定するコンデンサ取付装置において、前記コンデンサ取付部品は、形状がブロック状であって、前記コンデンサの半円もしくは半だ円部の周部のみを両方向から挟み込む面と、前記コンデンサの前記直線部が前記基板表面に接触するように取付け固定する取付ネジを有することを特徴とするコンデンサ取付装置を提供するものである。
また、断面が半円もしくは半だ円部と直線部からなる長円形のコンデンサを、基板表面に取付け固定するコンデンサ取付方法において、ブロック状の取付治具を前記コンデンサの前記半円周もしくは半だ円部の周部のみに両方向から挟み込むように設け、取付ネジにより、前記コンデンサの前記直線部が前記基板表面に接触するように取付け固定するとともに、前記コンデンサの側面外周部に設けた凹部と、前記取付部品に設けた凸部とを嵌合することを特徴とするコンデンサ取付方法を提供するものである。 The present invention is an oval capacitor section consists of semi-circular or semi-elliptical portion and a straight portion, the capacitor mounting apparatus for mounting fixed to the substrate surface by the capacitor mounting part, wherein the capacitor mounting parts, shape with blocky The capacitor has a surface for sandwiching only the peripheral portion of the semi-circle or semi-ellipse portion of the capacitor from both directions, and an attachment screw for attaching and fixing the linear portion of the capacitor so as to contact the substrate surface. A capacitor mounting device is provided.
Further, an oval capacitor section consists of semi-circular or semi-elliptical portion and a straight portion, the capacitor mounting method for mounting fixed to the substrate surface, but the semicircular or semi said capacitor block-shaped attachment jig Provided so as to be sandwiched only in the circumferential part of the circular part from both directions, and fixed with the mounting screw so that the linear part of the capacitor is in contact with the substrate surface, and a recess provided in the outer peripheral part of the side surface of the capacitor, The capacitor mounting method is characterized in that a convex portion provided on the mounting part is fitted.

本発明は、取付部品でコンデンサを両端からはさむ構成なので、高さ方向の省スペース化を図ることができる。
また、取付部品がブロック状であるために、両端からコンデンサをはさむ構成であっても十分な保持強度を得ることができるし、また、コンデンサ側面からの放熱も取付部品を通してスムーズに行うことができる。
また、取付部品に上記長円形電解コンデンサのケース外周部の凹部と等しい形状の突起を付けることで、取付部品ではさむ方向とは直角方向の耐振動性の向上も図ることができる。
Since the present invention has a configuration in which the capacitor is sandwiched from both ends by mounting parts, space saving in the height direction can be achieved.
In addition, since the mounting parts are block-shaped, sufficient holding strength can be obtained even if the capacitor is sandwiched from both ends, and heat can be radiated from the side of the capacitor smoothly through the mounting parts. .
Further, by attaching a protrusion having the same shape as the concave portion of the outer peripheral portion of the case of the elliptical electrolytic capacitor to the mounting part, it is possible to improve the vibration resistance in the direction perpendicular to the direction sandwiched by the mounting part.
