As shown in the side view of Fig. 1, the standoff mounting screw 1 has a threaded part 1a on the rod body, and a standoff part 1b on both sides of the male threaded part 1a and a plurality of stages (three stages in the figure) having different diameters. The substrate support portions 1c shown in FIG. The heights H 1 , H 2 , and H 3 of each stepped portion (borderline between large and small diameters) from the end of the male threaded portion 1a are set corresponding to the standoff height of the circuit board 2 shown by the two-dot chain line, and various heights are set. Standoff mounting screws with a height are provided. This standoff mounting screw 1 has a male threaded portion 1a that is screwed into and erected on the mounting member 3 shown by the two-dot chain line, and the circuit board 2 is inserted into any one of the multiple steps of the board support portion 1c, and the circuit board 2 is inserted into one of the steps of the board support portion 1c.

Note that the first step of the standoff portion 1b and the substrate support portion 1c does not need to have a step with respect to the male threaded portion 1a, if there is no other problem, and may be an extension of the male threaded portion 1a itself.
【００１０】 つぎに、このスタンドオフ取付ねじを用いた回路基板のスタンドオフ取付構造 について説明する。 図２の一部破断を含む側面図に示すように、図１のスタンドオフ取付ねじ１を 複数本用い、回路基板２を被取付部材３、即ち電子回路モジュールの構成する金 属ケースにスタンドオフし固定・収納する。即ち、金属ケース３の底部3aに穿設 したねじ孔3a-1にスタンドオフ取付ねじ１のおねじ部1aを螺着・立設すると共に スタンドオフ部1bを底部3a外面に貫通突出する。一方、回路基板２は、スタンド オフ取付ねじ１の基板支持部1cの複数段の内の回路基板２のスタンドオフ高さに 対応する段（図は２段目）に嵌入する支持孔2aを予め穿設しておく。その回路基 板２を基板支持部1cの当該段に嵌入し段差部で支持しスタンドオフする。支持さ れた回路基板２は基板周縁に形成した複数箇所のランド2bを金属ケース３の側壁 3b内面に半田付けにより接地接合する。0010 Next, we will introduce the circuit board standoff mounting structure using this standoff mounting screw. I will explain about it. As shown in the partially broken side view of Figure 2, the standoff mounting screw 1 of Figure 1 is A plurality of circuit boards are used, and the circuit board 2 is connected to the mounting member 3, that is, the metal constituting the electronic circuit module. Secure and store by stand-off in the case. That is, it is drilled in the bottom 3a of the metal case 3. Screw the male threaded part 1a of the standoff mounting screw 1 into the screw hole 3a-1 prepared and set it upright. The standoff portion 1b penetrates and protrudes from the outer surface of the bottom portion 3a. On the other hand, the circuit board 2 is At the standoff height of the circuit board 2 among the multiple stages of the board support part 1c of the off-mounting screw 1 A support hole 2a that fits into the corresponding step (the second step in the figure) is drilled in advance. The circuit board The plate 2 is inserted into the corresponding step of the substrate support portion 1c, supported by the step portion, and stands off. supported The printed circuit board 2 has multiple lands 2b formed on the periphery of the board on the side wall of the metal case 3. Connect the ground to the inner surface of 3b by soldering.
【００１１】 そして更に本実施例では、電子回路モジュールは従来どおりに母回路基板にス タンドオフ搭載する。即ち、金属ケース３の取付面（底部3a外面）に突出するス タンドオフ取付ねじ１のスタンドオフ部1bを母回路基板４の部品実装面に当接し 、回路基板２に圧入植設した接続端子2cを金属ケース３の底部3aに穿設したばか 孔3a-2に貫通し、母回路基板４のスルーホール4aに半田付けし固着する。[0011] Furthermore, in this embodiment, the electronic circuit module is inserted onto the mother circuit board as before. Equipped with standoff. In other words, the strip that protrudes from the mounting surface of the metal case 3 (the outer surface of the bottom 3a) Touch the standoff part 1b of the standoff mounting screw 1 to the component mounting surface of the mother circuit board 4. , the connection terminal 2c press-fitted into the circuit board 2 is drilled into the bottom 3a of the metal case 3. It penetrates through the hole 3a-2 and is fixed by soldering to the through hole 4a of the mother circuit board 4.
【００１２】 なお、上記説明の回路基板に代わり、他の回路基板を他の異なるスタンドオフ 高さに支持する場合は、その回路基板の支持孔の直径を変えて他の段の段差部で 支持することにより、例えば図２の２点鎖線で示す他のスタンドオフ高さに支持 できることは言うまでもない。0012 Note that instead of the circuit board described above, use another circuit board with different standoffs. When supporting the circuit board at different heights, change the diameter of the support hole of the circuit board and By supporting the It goes without saying that it can be done.
【００１３】 このように、スタンドオフ取付ねじは、棒体におねじ部を備え該おねじ部の両 側にスタンドオフ部と直径が異なる複数段の基板支持部をそれぞれ備えることに より、被取付部材（金属ケース）におねじ部で螺着・立設することができ、回路 基板にスタンドオフ高さに対応する基板支持部の段に嵌入する孔を穿設しておく ことにより、その回路基板の支持孔は基板支持部の段に一義的に嵌入されること になり、回路基板を段差部で支持し所定のスタンドオフ高さに支持することがで きる。同様に他の回路基板に他の異なるスタンドオフ高さに対応する基板支持部 の段に嵌入する孔を穿設しておくことにより、同一のスタンドオフ取付ねじだけ で回路基板を種々のスタンドオフ高さ（図２の実施例では３種類）に支持するこ とができる。また、回路基板の支持孔をスタンドオフ取付ねじに嵌入支持するこ とにより、回路基板を被取付部材に対し位置決めすることができるため、上記実 施例のように金属ケースの側壁内面にランドを半田付けする際に壁面との隙間を 正確に維持し半田付け作業を容易に行うことができる。[0013] In this way, the standoff mounting screw has a threaded part on the rod and both sides of the male threaded part. Each side is equipped with a standoff part and multiple board support parts with different diameters. This makes it possible to screw onto and erect the mounting member (metal case) using the threaded part, and the circuit Drill a hole in the board that fits into the step of the board support part corresponding to the standoff height. As a result, the support hole of the circuit board is uniquely fitted into the step of the board support part. This allows the circuit board to be supported at the step and at a predetermined standoff height. Wear. Board supports accommodate other different standoff heights on other circuit boards as well By drilling a hole that fits into the step of the standoff, only the same standoff mounting screw can be used. The circuit board can be supported at various standoff heights (three in the embodiment of FIG. 2). I can do that. It is also possible to insert the support hole of the circuit board into the standoff mounting screw and support it. This allows the circuit board to be positioned relative to the component to be mounted. As shown in the example, when soldering a land to the inner surface of the side wall of a metal case, make sure to keep the gap between the land and the wall surface. It can be maintained accurately and soldering work can be done easily.
