Embodiment Construction

[0101] based on Figure 1 to Figure 16 Embodiments of the electromagnetic relay of the present invention will be described.

[0102] Such as Figure 1 to Figure 8 As shown, the electromagnetic relay of the first embodiment is roughly composed of a base 10, an electromagnet unit 20, a fixed contact terminal 30, a movable contact terminal 40 riveted and fixed to a movable contact piece unit 50, a rotating operating body 60, and an operation The plate 70, the stopper plate 80, the insulating shielding plate 85, and the cover 90 are comprised.

[0103] The base 10 has a plane square box shape, such as figure 2 As shown, the partition wall 11 is protruded from the bottom surface thereof, and a fitting step portion 11 a is formed on the upper side of the inward surface of the partition wall 11 . In addition, the base 10 is provided with a pair of terminal slits 12 a and 12 b on a side wall forming one internal space partitioned by the partition wall 11 . In addition, a press-fi...

Abstract

The present invention provides an electromagnetic relay capable of preventing heat generation due to consumption of powder accompanying switching operations of contacts. Therefore, the electromagnetic relay of the present invention causes a plurality of movable contacts arranged side by side to come into contact with and separate from a plurality of opposite fixed contacts arranged side by side via an operating plate that reciprocates as the electromagnet unit is energized. In particular, the movable contact (57) and the fixed contact (31) on one side that can contact and separate from each other and the movable contact (58) on the other side that can contact and separate from each other. ) and the fixed contact (32), a shielding plate (85) is arranged between them.

Description

technical field [0001] The present invention relates to electromagnetic relays, and more particularly to electromagnetic relays having a double-contact configuration. Background technique [0002] Conventionally, as an electromagnetic relay having a double contact, for example, there is a configuration in which the spring device 33 is divided into two in the width direction, and the contact buttons 37 and 37 are respectively provided on a split piece. Furthermore, the spring device 33 is rotated by the operating arm 22 reciprocatingly moving along with switching of the direction of energization to the coil device 12, so that the contact buttons 37, 37 of the spring device 33 are respectively connected to the contacts provided on the terminal 31. The contact buttons 34 and 34 are brought into contact and separated (refer to Patent Document 1). [0003] Patent Document 1: (US) Patent No. 7659800 [0004] However, in the above-mentioned electromagnetic relay, the contact butt...
