Electromagnetic relay

Номер: US20120256713A1

Автор: Hitoshi Sunohara, Masanao Sugisawa, Shigeki Fujii

Принадлежит: Individual

In an electromagnetic relay, length from a movable contact to an end portion of a movable element on a first end side is set greater than length from the movable contact to another end portion of the movable element on a second end side opposite to the first end side. A direction of a Lorentz force acting on a portion of the movable element from the movable contact to the end portion of the movable element on the first end side is conformed to a direction for bringing fixed contacts and movable contacts into contact with each other. Thus, separation between the movable contacts and the fixed contacts due to an electromagnetic repulsive force can be inhibited.

A contact mechanism is capable of, without enlarging the entire configuration thereof, preventing the generation of an electromagnetic repulsion that opens a movable contact upon application of a current, and also provides an electromagnetic contactor that uses this contact mechanism. A contact mechanism has a fixed contact and a movable contact that are inserted in a current-carrying path. In the contact mechanism, the fixed contact or the movable contact is formed into an L-shape or a U-shape so as to generate a Lorentz force that acts against an electromagnetic repulsion in an opening direction, which is generated between the fixed contact and the movable contact upon application of a current.

A keyswitch structure includes a base, a keycap, a frame disposed between the base and the keycap for providing a supporting and moving mechanism to the keycap, and another frame interacting with the former frame through a magnetic attraction force. When the keycap is not pressed, the magnetic attraction force drives the two frames to stably stand on the base and form a stable supporting structure, so that the keycap is located at a farther position relative to the base. When the keycap is pressed with an external force to move toward the base, the magnetic attraction force is overcome so that the two frames depart from each other; that is, the above stable supporting structure is temporarily destroyed.
