Abstract

A relay includes an electromagnet, a plurality of springs having contacts which open and close in accordance with operation of the electromagnet and terminals, and a base which supports the springs, wherein at least one of the plurality of springs has a locked part which is locked on the base using resilience of the spring, and the base has a lock part which locks the locked part.

Claims (14)

1. A relay, comprising:

an electromagnet,

a spring which includes a contact which opens and closes in accordance with operation of the electromagnet, and a terminal, and

a base which supports the spring, wherein:

the base includes an insertion hole into which the terminal is inserted, and a reference surface, which is an inside surface of the insertion hole, defining a reference position of the spring, and

the base includes a notch on the reference surface side near a terminal outlet of the insertion hole provided at a bottom of the base through which a front end of the terminal is exposed, so that a first width of the insertion hole in a direction perpendicular to a longitudinal direction of the insertion hole at the bottom of the base is larger than a second width of the insertion hole in the direction perpendicular to the longitudinal direction of the insertion hole at an upper part of the base where the notch is not formed.

2. The relay according to claim 1 , wherein the notch extends across an entire width of the insertion hole.

3. The relay according to claim 1 , wherein the notch has an inclined surface which is inclined with respect to the reference surface.

4. A relay, comprising:

an electromagnet,

a spring which includes a contact which opens and closes in accordance with operation of the electromagnet, and a terminal, and

a base which supports the spring, wherein:

the base includes an insertion hole into which the terminal is inserted, and a reference surface, which is an inside surface of the insertion hole, defining a reference position of the spring, and

the base includes a region formed by lowering an area of the insertion hole around the terminal at a bottom of the base, so that a first width of the insertion hole in a direction perpendicular to a longitudinal direction of the insertion hole at the bottom of the base is larger than a second width of the insertion hole in the direction perpendicular to the longitudinal direction of the insertion hole at an upper part of the base where the region is not formed.
