Embodiment Construction

[0045] Hereinafter, a relay according to an embodiment will be described with reference to the drawings. It should be noted that, in the following description, directions such as up, down, left, and right are used for convenience of description, and the above-mentioned directions represent directions when the relay is viewed in a certain state, and do not limit the installation direction of the relay.

[0046] figure 1 and figure 2 It is a perspective view of the relay 1 of 1st Embodiment. image 3 is an exploded view of Relay 1. Figure 4 is a side view of relay 1. The relay 1 includes a first contact portion 2 , a second contact portion 3 , a driving portion 4 , a pressing member 5 , a base 6 , and a restricting member 7 .

[0047] The first contact portion 2 is formed of a conductive material. Such as image 3 and Figure 4 As shown, the first contact part 2 has a first contact piece 21 , a first terminal 22 , a first contact 23 and a first fixing part 24 . The fir...

Abstract

A pressing member is provided so as to press against a portion of a first contact piece between a first terminal and a first contact point. The pressing member moves from an off position to an on position, and presses the first contact piece toward a second contact piece, whereby the first contact point contacts a second contact point. When the pressing of the pressing member is stopped, the first contact point and the second contact point lose contact due to the elastic force of the first contact piece, and the pressing member is pushed back by the first contact piece, moving from the on position to the off position. Before the pressing member reaches the off position from the on position, the movement of the first contact piece is restricted by a restricting member.

Description

technical field [0001] The present invention relates to relays. Background technique [0002] The relay has a configuration in which a push member is operated by a drive unit such as an electromagnet to switch contacts. For example, in the electromagnetic relay of Patent Document 1, the pressing member presses the movable contact piece against the fixed contact piece by exciting the electromagnet. As a result, the movable contact provided on the movable contact piece comes into contact with the fixed contact provided on the fixed contact piece. In addition, by demagnetizing the electromagnet, the pressing member is pushed back by the elastic force of the movable contact piece. Thereby, the movable contact is separated from the fixed contact. [0003] Patent Document 1: (Japanese) Unexamined Patent Application No. 2001-143593 [0004] In order to reduce the amount of movement of the pressing member as much as possible and increase the amount of movement of the contacts at...
