Embodiment Construction

[0034] Embodiments of the present invention will be described below with reference to the drawings. In addition, in the description of the present application, terms indicating directions, positions, etc. (for example, "upper", "lower", "edge", "side" and other terms including these) are used appropriately, but these terms Directions, positions, and the like in the drawings for explanation are shown only, and the present invention is not limitedly interpreted by these terms.

[0035] (structure)

[0036] 1 to 3 show the electromagnetic relay of this embodiment. In this electromagnetic relay, the electromagnet block 2, the movable iron piece 3, the contact opening and closing mechanism part 4, and the card 5 are generally installed on the base 1, and after the case 6 is covered, the sealing agent injected into the fitting part and the like is used. Make the inside a closed state.

[0037] Such as Figure 7 As shown, the base 1 has a first holding part 7 for holding the elec...

Abstract

An electromagnetic relay is small, but ensures sufficient stroke volume and insulating distance. The electromagnetic relay of the invention excites and erases an electromagnetic iron (2), attracts and keeps away from the movable iron sheet (3) to the magnetic pole piece (25) of the iron core (21) to move, and the card (5) moves to and fro, to drive the movable contact sheet (41), and close the contact; the electromagnetic iron (2) is collocated on the base (1), and composed by the scroll (22) coiling the winding (23) on the iron core (21). The card (5) is guided to and fro on the base (1), including: an avoidance part (59), a flange part (27) collocated at one side of the scroll (22) of the electromagnetic iron (2) on the base (1) can move in the avoidance part (59); a guiding part (60), which holds one end part of the movable iron sheet (3). The scroll (21) has a cylindrical body part (26) coiling the winding (23) and flange parts (27, 33) formed at two ends of the body part (26) respectively. The flange part (27) has a step part (31), which avoids interference with the position of the adjacent avoidance part (59) of the guiding part (60).

Description

technical field [0001] The invention relates to an electromagnetic relay. Background technique [0002] As a conventional electromagnetic relay, there is known a technique in which a movable iron piece is attracted to the magnetic pole portion of the core by exciting and demagnetizing an electromagnet block constituted by winding a coil around an iron core via a reel, The card is moved away and rotated to reciprocate, thereby driving the movable contact piece to open and close the contacts (for example, refer to Patent Document 1). [0003] Patent Document 1: (Japanese) Unexamined Patent Publication No. 4-272628 [0004] However, in the above conventional electromagnetic relay, the structure for downsizing is insufficient, and a sufficient amount of stroke cannot be ensured when the movable contact piece is driven, or the insulation distance cannot be maintained sufficiently. [0005] In addition, in the above conventional electromagnetic relay, even if a thickness gauge i...
