Abstract
An electromagnetic relay includes a base, a spool provided on the base, a coil wound on the spool, a yoke inserted into a hole formed in the spool, an armature movably disposed on the base, a movable contact fixed on the base, a static contact fixed on the base, a driving member connected between the armature and the movable contact, and an elastic pressing member fixed on the base. The elastic pressing member is pressed against an outer side of the armature so as to position the armature on the base and provide an auxiliary thrust to the armature.
Claims21
An electromagnetic relay, comprising:
- a base;
- a spool provided on the base;
- a coil wound on the spool;
- a yoke inserted into a hole formed in the spool;
- an armature movably disposed on the base;
- a movable contact fixed on the base;
- a static contact fixed on the base;
- a driving member connected between the armature and the movable contact;
- and
- an elastic pressing member fixed on the base and pressed against an outer side of the armature so as to position the armature on the base and provide an auxiliary thrust to the armature urging the armature toward the coil.
An electromagnetic relay, comprising:
- a base;
- a spool provided on the base;
- a coil wound on the spool;
- a yoke inserted into a hole formed in the spool;
- an armature movably disposed on the base and having a main body and a lower end portion bent perpendicularly relative to the main body of the armature so that the armature is L-shaped, an end of the base adjacent to the spool has a receiving slot into which the lower end portion of the armature is received;
- a movable contact fixed on the base;
- a static contact fixed on the base;
- a driving member connected between the armature and the movable contact;
- and
- an elastic pressing member fixed on the base and pressed against an outer side of the armature so as to position the armature on the base and provide an auxiliary thrust to the armature urging the armature toward the coil, the elastic pressing member having a base part fixed on the base and an elastic sheet connected to the base part and elastically pressed against the outer side of the armature, wherein the lower end portion of the armature is supported on the base part of the elastic pressing member, the base part of the elastic pressing member is fixed in the receiving slot of the base in an interference fit manner.
An electromagnetic relay, comprising:
- a base having a receiving slot formed on an end thereof,
- a spool provided on the base;
- a coil wound on the spool;
- a yoke inserted into a hole formed in the spool;
- an armature movably disposed on the base and within the receiving slot;
- a movable contact fixed on the base;
- a static contact fixed on the base;
- a driving member connected between the armature and the movable contact;
- and
- an elastic pressing member having a base part positioned within the receiving slot of the base and an elastic sheet pressed against an outer side of the armature so as to position the armature on the base and provide an auxiliary thrust to the armature urging the armature toward the coil.
