Abstract
An electromagnetic relay includes a first fixed terminal, a base, and a magnet. The first fixed terminal includes a first fixed contact. The base holds the first fixed terminal. The base includes a magnet insertion hole disposed in a vicinity of the first fixed contact. The magnet insertion hole has an opening opened toward the first fixed terminal. The magnet is disposed in the magnet insertion hole and is prevented from coming off from the magnet insertion hole by the first fixing terminal.
Claims10
An electromagnetic relay comprising:
- a first fixed terminal including a first fixed contact;
- a base configured to hold the first fixed terminal, the base including a magnet insertion hole disposed in a vicinity of the first fixed contact, the magnet insertion hole having an opening opened toward the first fixed terminal;
- and
- a magnet disposed in the magnet insertion hole, the magnet prevented from coming off from the magnet insertion hole by the first fixed terminal;
- wherein the first fixed terminal further includes a contact support portion and a first extending portion, the contact support portion being configured to support the first fixed contact, the first extending portion extending at an angle from the contact support portion and protruding outward from the base,
- the first fixed terminal further includes a second extending portion connected to the contact support portion, the second extending portion facing the first extending portion, and
- the magnet insertion hole is disposed between the first extending portion and the second extending portion.

An electromagnetic relay, comprising:
- a non-conductive base including a non-conductive terminal support portion extending from the base toward the interior of the electromagnetic relay, the terminal support portion including a cup-shaped or pocket-shaped magnet insertion hole with a magnet disposed therein;
- a fixed terminal that overlies and is supported by the terminal support portion, with the fixed terminal being positioned to block the magnet from coming out from the magnet insertion hole, the fixed terminal including a fixed contact;
- and
- a movable contact piece including a movable contact facing the fixed contact, wherein
- the cup-shaped or pocket-shaped magnet insertion hole has a concave shape in a first direction from the movable contact toward the fixed contact, a bottom surface extending in a direction intersecting the first direction, a inner surface extending from the bottom surface in a second direction opposite to the first direction, and a covered or blocked opening that is oriented toward the second direction.
