CIRCUIT CONTROLLER AND ELECTRIC SWITCH MACHINE
To prevent intrusion of living things such as insects from a connection part with a jack plate in a circuit controller for an electric switch machine.SOLUTION: In a circuit controller 2, a cover part 12 covering a base part 10 to define an inner space 16 is engaged with a female screw part 82 of a jack plate 80 inserted in an insertion hole 17 with a fastening screw 70, and is connected to the jack plate 80. The fastening screw 70 has: a rod part 71 passing through the inner space 16; a rotation operation part 72 provided on a head part protruding from a top surface of the cover part 12; and a male screw part 73 positioned in the insertion hole 17 and provided on a lower part of the rod part 71. The circuit controller 2 makes a closing member 75 for a rod close a gap in the insertion hole 17 generated in a connection state where the male screw part 73 and the female screw part 82 are screwed with each other.SELECTED DRAWING: Figure 3
【課題】電気転てつ機用の回路制御器において、ジャック板との連結部からの虫等の生物侵入を防止すること。【解決手段】回路制御器２は、基部１０を覆って器内空間１６を画成するカバー部１２を、締付ネジ７０で挿通孔１７に挿通されたジャック板８０の雌ネジ部８２に螺合させて、ジャック板８０へ連結される。締付ネジ７０は、器内空間１６を貫通するロッド部７１と、カバー部１２の上面から突出する頭部に設けられた回転操作部７２と、挿通孔１７内に位置し、ロッド部７１の下部に設けられた雄ネジ部７３と、を有する。回路制御器２は、雄ネジ部７３と雌ネジ部８２とが螺合した連結状態において生じる挿通孔１７内の隙間を、ロッド用閉塞部材７５で閉塞する。【選択図】図３
