Highly-reliable insulating ultra-small electromagnetic relay

A highly-reliable insulating ultra-small electromagnetic relay, comprising

• a coil portion and a static spring portion;
• the coil portion comprising a bobbin;
• the bobbin comprising two flanges, each of the two flanges being arranged at one of both ends of the bobbin;
• the static spring portion comprising a static spring on at least one end of the bobbin;
• wherein the static spring comprises
• a contact portion containing a static contact;
• the contact portion is arranged at a position close to the flange of the bobbin;
• and
• the flange comprises a first retaining wall and a second retaining wall protruded upwardly for jointly limiting a position of the contact portion of the static spring in two directions on a horizontal plane, a wall surface of the first retaining wall is arranged along a width direction of the relay, a wall surface of the second retaining wall is arranged along the length direction of the relay, the second retaining wall and the first retaining wall enclose into a “L” shape, the contact portion of the static spring is located inside the “L” shape, such that the first retaining wall and the second retaining wall are cooperated with the contact portion of the static spring to avoid uncontrollable dispersion at the position of the contact portion of the static spring when being assembled.
