Electromagnetic relay
First Claim
1. An electromagnetic relay comprising:
- a base;
an electromagnet fitted to said base; and
a contact section fitted to said base and operable to open or close with an operation of said electromagnet;
wherein said electromagnet includes;
a bobbin;
a coil having a center axis and wound and supported on said bobbin;
an iron core incorporated into said bobbin and disposed along said center axis of said coil; and
a yoke extending from said iron core to an outside of said bobbin and said coil;
wherein said base includes;
a retaining face firstly contacting with at least one of said yoke and said bobbin, in an action of fitting said electromagnet to said base, and retaining said electromagnet at a predetermined height on said base as seen in a direction of said center axis of said coil; and
a guide face slidably engaged with said at least one of said yoke and said bobbin, by shifting said at least one of said yoke and said bobbin along said retaining face, and guiding said electromagnet in a fitting direction intersecting with said center axis;
said retaining face and said guide face cooperating with each other to fixedly support said electromagnet at a predetermined fitting position on said base.

Abstract
An electromagnetic relay including a base, an electromagnet fitted to the base, and a contact section operable to open or close with an operation of the electromagnet. The base includes a retaining face firstly contacting with the yoke of the electromagnet, in an action of fitting the electromagnet to the base, and retaining the electromagnet at a predetermined height on the base as seen in a direction of the coil center axis of the electromagnet. The base also includes a guide face slidably engaged with the yoke, by shifting the yoke along the retaining face, and guiding the electromagnet in a fitting direction intersecting with the coil center axis. The retaining face and the guide face cooperate with each other to fixedly support the electromagnet at a predetermined fitting position on the base.
