本考案は、リレー等の電気、電子機器における
プリント基板の固定構造に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a structure for fixing a printed circuit board in electrical or electronic equipment such as a relay.

ものである。[Summary of the invention] The present invention has a structure in which a printed circuit board is clamped between a case and a cover that are fitted and fixed to each other. The periphery of the printed circuit board is crimped and clamped between the two, and the printed circuit board is fixed so that it will not rattle or be subjected to unreasonable loads due to the repulsive force of the cover itself caused by the warping of the cover that occurs at this time.
［従来技術とその問題転］
従来、この種のプリント基板の固定構造として

の周部を挾着したものが提供されている。[Prior Art and its Problems] Conventionally, as shown in FIGS. 4 and 5, the fixing structure for this type of printed circuit board has been such that the opening 21 of the case 20 is fitted into the protrusion 26 of the cover 25. While integrating the two, the printed circuit board 30 is formed by the stepped portion 22 of the case 20 and the end surface 27 of the side wall portion of the cover 25.
It is provided with a clamp around the periphery.
しかしながら、これでは、ケース２０、カバー

下面に微小なクリアランスが生じてしまい、プリ
ント基板３０ががたつくこととなるのである。 However, in this case, unless the dimensional accuracy of the case 20, cover 25, and printed circuit board 30 is extremely accurate, the printed circuit board 30 cannot be fixed without wobbling. That is, due to variations in the dimensional accuracy of the three components, a minute clearance is created between the upper and lower surfaces of the printed circuit board 30, causing the printed circuit board 30 to wobble.
そのため、第６図に示すように、ケース２０の

いる。 However, in this case, the printed circuit board 3
Although the looseness of the printed circuit board 30 is eliminated, the printed circuit board 30 may warp, causing the pattern on the board 30 to be cut, the mounted components to be disconnected, and the printed circuit board 30 to be warped.
It has problems such as cracks occurring in itself.
［問題点を解決するための手段］
そこで、本考案に係るプリント基板の固定構造
は、ケースの側壁部内側に形成した段部と前記カ
バーの側壁部端面に形成した突起とでプリント基
板の周部を圧着挾持し、この圧着力にて前記カバ
ーに反りを発生せしめることを特徴とする。[Means for Solving the Problems] Therefore, the printed circuit board fixing structure according to the present invention uses a step formed on the inside of the side wall of the case and a protrusion formed on the end surface of the side wall of the cover to secure the printed circuit board around the circumference. The cover is crimped and clamped, and the crimping force causes the cover to warp.
［作用］
即ち、以上の構成にあつては、プリント基板は
周部をケースの段部とカバーの突起とで圧着固定
され、この圧着力はカバーが反ることにより吸着
され、プリント基板が反つたりすることはなくな
るのである。[Function] That is, in the above configuration, the peripheral portion of the printed circuit board is fixed by pressure between the stepped portion of the case and the protrusion of the cover, and this pressure is absorbed by the warping of the cover, and the printed circuit board warps. There will be no more sagging.
［実施例］
以下、本考案に係るプリント基板の固定構造の
一実施例について第１図、第２図、第３図を参照
して説明する。[Example] Hereinafter, an example of a printed circuit board fixing structure according to the present invention will be described with reference to FIGS. 1, 2, and 3.
ケース１は略箱状をなし、対向する側壁部２，
２の内側には段部４が形成され、いまひとつの対
向するする側壁部３，３には嵌合用開口５が形成
されているとともに、段部４と同一平面上に段部
６が形成されている。 The case 1 has a substantially box shape, and has opposing side walls 2,
A step portion 4 is formed on the inside of the step portion 2, and a fitting opening 5 is formed in the other opposing side wall portions 3, 3, and a step portion 6 is formed on the same plane as the step portion 4. There is.
カバー１０は略板状をなし、側壁部１１，１１
の端面には前記ケース１の段部４と対向する突起
１３が形成され、いまひとつの側壁部１２，１２
にはケース１の開口５に嵌合可能な突部１４が形
成されている。 The cover 10 has a substantially plate shape, and has side wall portions 11, 11.
A protrusion 13 facing the step part 4 of the case 1 is formed on the end face of the case 1, and another side wall part 12, 12
A protrusion 14 that can fit into the opening 5 of the case 1 is formed in the case 1 .
プリント基板１５はカバー１０の外周部と同形

よつてその反発力で常にケース１の段部４に圧着
され、がたつくことなく固定されるのである。 In the above configuration, the cover 10 and the case 20
are integrated by fitting the protrusion 14 into the opening 5. At this time, the peripheral portion of the printed circuit board 15 is crimped and clamped between the stepped portions 4 and 6 and the protrusion 13.
The pressure force of the protrusion 13 is received by the stepped portion 4 via the printed circuit board 15. When the case 1 and the cover 10 are fitted together, the distance between the stepped portion 4 and the protrusion 13 is set to be slightly smaller than the thickness of the printed circuit board 15, and the difference is as shown in FIG.
It is attracted by the bottom curved downward. That is, when the cover 10 warps, the printed circuit board 15 is always pressed against the stepped portion 4 of the case 1 by the repulsive force thereof, and is fixed without wobbling.
なお、突起１３は側壁部１１のみでなく、側壁
部１２に形成してもよい。 Note that the protrusion 13 may be formed not only on the side wall portion 11 but also on the side wall portion 12.
