Electromagnetic relay and method of making the same
View Patent ↗A electromagnetic relay in which bad electrical contact and failure of operation are prevented even when shavings are produced while an iron core is press-fitted into and mounted on a base. The electromagnetic relay includes an electromagnetic block supported by press-fitting both ends of an iron core of the electromagnetic block into an upper surface of a base and open or close a contact by a movable iron piece rotated by magnetization or demagnetization of the iron core with a coil, where shaving receptacles are made by forming separating ribs adjacent to at least one side of press-fit projections that are formed in press-fit concave portions provided on the upper surface of the base.
1. An electromagnetic relay configured to open or close a contact by a movable iron piece rotated by magnetization or demagnetization of the iron core with a coil, the electromagnetic relay comprising:
a base having a press-fit concave portion on an upper surface thereof, and
a press-fit projection formed in the press-fit concave portion, and
an electromagnetic block having an iron core, the electromagnetic block supported by press-fitting both ends of the iron core into the upper surface of the base, wherein
a separating rib is formed adjacent to at least one side of the press-fit projection to form a shaving receptacle.
2. The electromagnetic relay according to claim 1 , wherein
the shaving receptacle is formed at both sides of the press-fit projection by forming the separating rib at both sides of the press-fit projection.
3. The electromagnetic relay according to claim 1 , wherein a part of a spool is extended in proximity to an upper end of the shaving receptacle.
