Contact point device and electromagnetic relay that mounts the contact point device thereon

摘要

A contact point device 1 includes a drive block 2 that has a drive shaft 25 to which a movable contactor 29 is attached, and drives the movable contactor 29. The movable contactor 29 is attached to the drive shaft 25 so as to be movable relatively to the drive shaft 25 in an axial direction of the drive shaft, and in addition, relative movement thereof in the axial direction is regulated due to abutment of the movable contactor 29 against a regulating portion 60. Then, between the movable contactor 29 and the regulating portion 60 is formed a rotational movement deregulating portion 80, which relaxes the regulation by the regulating portion 60 for the relative rotational movement of the movable contactor 29 in the axial direction.

1. A contact point device comprising:
a contact point block including a fixed terminal in which a fixed contact point is formed, and a movable contactor in which a movable contact point contacting and separating from the fixed contact point is formed; and a drive block including a drive shaft to which the movable contactor is attached and which drives the movable contactor so that the movable contact point can contact and separate from the fixed contact point, wherein the movable contactor is attached to the drive shaft so as to be movable relatively to the drive shaft in an axial direction of the drive shaft, a regulating portion is provided, the regulating portion regulating a relative movement of the movable contactor in the axial direction by allowing the movable contactor to abut against the regulating portion itself, and a rotational movement deregulating portion is formed between the movable contactor and the regulating portion, the rotational movement deregulating portion relaxing the regulation by the regulating portion for the relative rotational movement of the movable contactor in the axial direction.
