The present invention relates to a power control device for a printed circuit board suitable for turning on and cutting off power to a printed circuit board equipped with an I-element.
プリント基板の複数の端子と接栓の端子の接触１分離に
順序をつける手段とし７て、従来、プリント板、の端子
部に例えばＶ字形の傾斜をつけ、中央部の端子が先に接
触し、両側は後で接触し、分離時はその逆になる様にし
たものがある。Conventionally, as a means of ordering contact and separation between a plurality of terminals on a printed circuit board and terminals on a plug, the terminals of the printed circuit board are sloped, for example, in a V shape, so that the terminals in the center come into contact first. In some cases, both sides come into contact later, and vice versa when separated.
しかしながら、このような従来のプリント板においては
、プリント板と接栓が平行な状態のまま挿入されないと
、接触２分離の順序が狂う欠点があった。例えば接栓に
対して斜めの状態で挿入すると、プリント板の端の端子
が先に接触することになり、プリント板内の回路の電源
投入装置が保たれない。However, such a conventional printed board has a drawback that if the printed board and the connector are not inserted in a parallel state, the order of contact and separation will be out of order. For example, if the plug is inserted at an angle to the plug, the terminal at the end of the printed board will come into contact first, and the circuit within the printed board will not be able to maintain power.
本発明の目的は、確実な接触１分離順序を守れる手段を
提供することＫよって、電源投入。SUMMARY OF THE INVENTION It is an object of the present invention to provide a means for ensuring a reliable contact-one-separation order when power is turned on.
切断順序を確実にし、プリント基板挿抜が原因となって
発生する例えばＣＭＯ８−ＬＳＩのラッテアップ発生を
防止することにある。The purpose is to ensure the cutting order and prevent the occurrence of latte-up in, for example, CMO8-LSI, which occurs due to insertion and removal of printed circuit boards.
本発明は、プリント板の挿抜時には必ず挿抜用取手を引
くまたは押すことに着目し、この取手とスイッチを連動
することによって上記目的を達成する。The present invention focuses on pulling or pushing the insertion/extraction handle whenever inserting/extracting a printed board, and achieves the above object by interlocking this handle with a switch.
以ド、本発明の一実施例を図面によシ説明する。第１図
は従来一般的な挿抜用取手付プリント基板を示したもの
で、１が挿抜用取手、２はプリント基板を示している。Hereinafter, one embodiment of the present invention will be explained with reference to the drawings. FIG. 1 shows a conventionally common printed circuit board with a handle for insertion/extraction, where 1 indicates the handle for insertion/extraction, and 2 indicates the printed circuit board.

２図で示した状態となシ、゛接点５と６は接触する。The printed circuit board 2 is inserted by applying force to the right in the figure, and the printed circuit board 2 is pulled out by pulling the handle 1 to the left. FIG. 2 shows an embodiment of the present invention. As shown, the present invention includes an insertion/extraction handle 1, a pair of springs 3, 10, a fixture 4, a fixed contact 5, a movable contact 6, a fixed contact electrode 7, a movable contact electrode 8,
It is composed of a spring fixing plate 9. When no force is applied to handle 1, the forces of spring 3 and spring 10 are combined,
Since the spring fixing plate 9 on the right side pushes up the movable contact 6, the contacts 5 and 6 come into contact with each other, as shown in FIG.

下方に復元力で下がるため接点５と６は離れる。FIG. 3 shows the state when it is pulled out, and FIG. 4 shows the state when it is inserted. In these cases, when inserting or removing the printed circuit board 2, force is first applied to the insertion/extraction handle 1 to the left or right, so the spring fixing plate 9 on the right side similarly moves to the left or right, and the movable contact 6 moves downward. The contact points 5 and 6 are separated because they are lowered by the restoring force.
すなわちプリント基板２の挿抜時には、挿抜用取手１を
操作するために必ず固定接点電極７゜可動接点６で構成
されたスイッチがＯＦＦすることになる。That is, when inserting or removing the printed circuit board 2, the switch composed of the fixed contact electrode 7 and the movable contact 6 must be turned OFF in order to operate the insertion/removal handle 1.

述のスイッチを経由して供給する。Here, in the electronic circuit configured on the printed circuit board 2,
When using A power supply and B power supply □ as two power sources, if a power sequence is required in which power is supplied in the order of A - + H when inserting the printed circuit board 2, and cut off in the order of B - + A when removing the printed circuit board 2, Power is supplied directly from the connector portion 2a of the printed circuit board 2 shown in FIG. 2, and power B is supplied via the above-mentioned switch.
