Embodiment Construction

[0049] Next, relay 1 according to the embodiment will be described with reference to the drawings. figure 1 It is a sectional view showing the relay 1 of the embodiment. like figure 1 As shown, the relay 1 includes a housing 2 , a contact device 3 and a drive device 4 .

[0050] The housing 2 accommodates a contact device 3 and a drive device 4 . Case 2 is formed of insulating resin. The contact device 3 and the drive device 4 are arranged in the housing 2 .

[0051] The contact device 3 includes a first fixed terminal 5 , a second fixed terminal 6 , a movable contact piece 7 and a contact piece holding portion 8 . The first fixed terminal 5, the second fixed terminal 6, and the movable contact piece 7 are formed of a conductive material. The first fixed terminal 5 includes a first fixed contact 11 . The second fixed terminal 6 includes a second fixed contact 12 . The first fixed contact 11 and the second fixed contact 12 are in the longitudinal direction of the movable...

Abstract

The present invention provides a relay capable of easily confirming characteristics while preventing occurrence of contact failure of contacts. A drive device is disposed in the contact direction withrespect to the movable touch piece. The drive device generates a driving force for moving the movable touch piece. The drive shaft extends in the movement direction of the movable touch piece. The drive shaft includes an end portion protruding in a separation direction from the movable touch piece. The drive shaft transmits the driving force to the movable touch piece. The first case accommodatesa first fixed contact, a second fixed contact, and the movable touch piece. The first case includes a test hole penetrating the first case. The test hole is disposed at a position facing the end portion of the drive shaft in the separation direction.

Description

technical field [0001] The present invention relates to relays. Background technique [0002] The relay has: a movable contact piece including a movable contact; and a fixed terminal including a fixed contact. The movable contact piece is connected to the drive shaft. The drive shaft is driven by a driving device such as a coil. As a result, the movable contact piece moves, the movable contact contacts or separates from the fixed contact, and the contact opens and closes. [0003] For example, in Patent Document 1, the movable contact piece and the fixed terminal are accommodated in a case. The drive shaft protrudes from the case toward the drive device, and the drive shaft is pulled toward the drive device by the drive device to bring the movable contact into contact with the fixed contact. [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanese Patent Laid-Open No. 2014-99373 [0007] When assembling a relay, it is necessary to c...
