Title: Electromagnetic relay
Inventor: TANAKA TAKESHI
IPC: H01H50/54
Filed: 2017-02-28
Abstract: PROBLEM TO BE SOLVED: To provide an electromagnetic relay which enables the downsizing while suppressing a mover from being tilted.SOLUTION: In an electromagnetic relay, a first guide 18a located in an exciting coil 12 and a second guide 18b located outside the exciting coil 12 form two contact points with a mover. Specifically, one leading end of a shaft 17 protrudes to outside the exciting coil 12, and the leading end of the shaft 17 thus protruding is moved to slide in the second guide 18b. Thus, the electromagnetic relay can be arranged in a structure in which one contact point is provided outside the exciting coil 12 can be arranged and as such, the size of the exciting coil 12 in its axial direction can be designed without factoring in the distance between two contact points. Therefore, the size of the exciting coil 12 in the axial direction can be reduced. Because of this, it becomes possible to achieve the downsizing of an electromagnetic relay while suppressing, by a mover guide 18, a mover from being tilted.SELECTED DRAWING: Figure 1
