Abstract
In an electromagnetic relay having a movable piece (30) supported so as to be free to oscillate, an electromagnet block (20) for attracting and oscillatingly displacing the movable piece by being excited, a contact mechanism having a movable contactor (53) and a fixed contactor (51, 52), a slide card (60) connecting a free end of the movable piece and the movable contactor, and a housing comprising a base (10) and a case (70), a supporting projection (71) is formed on the inner surface of the case (70) and the projection comes into abutting contact with the upper surface of a frame (11) of the base, thereby assuring a space within which the slide card may move. The slide card is formed to have a hole (61) so that the card will avoid the supporting projection.
Claims8
An electromagnetic relay having a movable piece supported so as to be free to oscillate,
- an electromagnet block for attracting and oscillatingly displacing said movable piece,
- a contact mechanism having a movable contactor and a fixed contactor,
- a connecting member connecting a free end of said movable piece and said movable contactor,
- a housing for internally accommodating each of these elements, and
- a supporting projection for assuring a space within which said connecting member is freely movable, said supporting projection formed on one of a face of said housing and a partial face of any element accommodated within said housing, which faces oppose each other with said connecting member interposed between them in spaced relation thereto, said supporting projection in abutting contact with the other of said faces,
- said connecting member having an avoiding shape formed therein such that, despite movement of said connecting member along a longitudinal direction thereof, said connecting member avoids said supporting projection without contacting said supporting projection, said avoiding shade being at least one of a hole and a cut-out.

- said connecting member having an avoiding shape formed therein such that, despite movement of said connecting member along a longitudinal direction thereof, said connecting member avoids said supporting projection without contacting said supporting projection, said avoiding shape being at least one of a hole and a cut-out, wherein
- said electromagnet block includes a yoke, and a lower end portion of said movable piece is supported, so as to be free to oscillate, on a distal end portion of the yoke, one face at the lower end portion of said movable piece is in contact with a distal-end face of said yoke, the distal-end face of said yoke is formed to have at least one inclined surface, and a lower edge and an upper edge of the inclined surface are so adapted as to act as fulcrums of oscillation of said movable piece.
