Relay
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.
1. A relay, comprising:
a base;
an electromagnet mounted on the base; and
a spring inserted into the base, the spring including a contact which opens and closes with another contact in accordance with operation of the electromagnet, a terminal, and a raised part formed by folding a portion of the spring,
wherein the raised part elastically deforms due to its resilience when the raised part receives an external force, and
the base has a lock part which locks an end of the raised part positioned opposite to an insertion direction in which the spring is inserted into the base, so as to limit a movement of the spring in the insertion direction.
2. The relay according to claim 1 , wherein the base has a reference surface defining a reference position of the springs, and
the raised part is formed by cutting and raising a portion of the spring and which press the spring against the reference surface.
3. A relay, comprising:
a base;
an electromagnet mounted on the base; and
a spring inserted into the base, the spring including a contact which opens and closes with another contact in accordance with operation of the electromagnet, a terminal, a raised part which is raised from a surface of the spring, and a locked part,
wherein the locked part elastically deforms due to its resilience when the locked part receives an external force,
wherein the base has a reference surface defining a reference position of the spring, and a lock part which locks an end of the locked part positioned opposite to an insertion direction in which the spring is inserted into the base, so as to limit a movement of the spring in the insertion direction, and
wherein the raised part presses the spring against the reference surface.
4. The relay according to claim 3 , wherein the locked part is formed by folding a portion of the spring.
5. The relay according to claim 3 , wherein the raised part is a protrusion which protrudes from a surface of the spring.
