<P>PROBLEM TO BE SOLVED: To provide a contact device that can suppress enlargement of the device and realize larger contact pressure. <P>SOLUTION: The contact device includes: a pair of fixed terminals 33 each having a fixed contact 32; a movable contact 35 with a pair of movable contacts 34 that respectively contact to and separate from the fixed contacts 32 and are arranged on a top surface of the movable contact 35; a yoke contact part 52 that faces the top surface of the movable contact 35 between the movable contacts 34 and restricts movement of the movable contact 35 to a side of the fixed contact 32; a yoke plate 6 that is disposed on the movable contact 35 at an undersurface side thereof and whose top surface faces a yoke contact part 52 across the movable contact 35; a contact pressure spring 36 that biases the movable contact 35 toward the fixed contact 32; an shaft part 51 connected to the yoke contact part 52; and an electromagnet block 2 for driving the shaft part 51 such that the movable contacts 34 respectively contact to and separate from the fixed contacts 32. The yoke contact part 52 has a first widening part 521 on a front end side thereof which is formed so as to gradually widen in the horizontal direction toward the front, and a second widening part 522 on a rear end side thereof which is formed so as to gradually widen in the horizontal direction toward the rear. <P>COPYRIGHT: (C)2012,JPO&INPIT |
