Embodiment Construction

[0062] Hereinafter, a relay according to an embodiment will be described with reference to the drawings. figure 1It is a perspective view of the relay 1 of 1st Embodiment. figure 2 It is a plan view of the relay 1 of 1st Embodiment. The relay 1 has a base body 11 , an electromagnet unit 12 , an armature unit 13 , a connection body 14 , a movable contact piece 15 , a movable contact terminal 16 , and a fixed contact terminal 17 .

[0063] The base body 11 accommodates the electromagnet unit 12 , the armature unit 13 , the connecting body 14 , the movable contact piece 15 , the movable contact terminal 16 , and the fixed contact terminal 17 . A cover member (not shown) is attached to the base body 11 .

[0064] The electromagnet unit 12 generates an electromagnetic force that rotates the armature unit 13 . Such as figure 2 As shown, the electromagnet unit 12 has a coil 21 , a reel 22 , a first yoke 23 and a second yoke 24 . The coil 21 is wound on a bobbin 22 . An iron c...

Abstract

A contact piece unit is provided with a terminal, a contact piece, and a contact point. The contact piece has a plurality of plate springs. The plate springs are disposed by being stacked to each other, and are bonded to the terminal by riveting. The contact point is bonded to the plate springs by riveting. The contact piece is welded such that the contact piece is electrically connected to the contact point and / or the terminal.

Description

technical field [0001] The invention relates to a contact piece unit and a relay. Background technique [0002] A relay has a structure including a contact piece in which a plurality of leaf springs are laminated. Engage the contacts on the contact piece. For example, in the relay described in Patent Document 1, three leaf springs are laminated and integrally joined to terminals. When the plurality of leaf springs laminated in this way are integrally joined to the terminal, the plurality of terminals are joined to the terminal by caulking. In addition, in order to integrally join the contact to the plurality of leaf springs, the contact is joined to the plurality of leaf springs by caulking. [0003] In detail, the protrusions of the terminals are inserted into the holes through which the plurality of plate springs pass, and the protrusions are deformed under pressure. Thereby, a plurality of leaf springs can be integrally joined to the terminal. In addition, the end po...
