Abstract
An electromagnetic relay with a contact mechanism portion being arranged above an electromagnet portion secured to a base, wherein the electromotive portion is inserted under pressure into the base, is secured, and also, the respective terminals of the contact mechanism portion are inserted under pressure from above into the base and are secured, whereby the electromagnet portion is seucred through the direct pressure insertion thereof into the base, the positional accuracy with respect to the base is increased.
Claims11
An electromagnetic relay comprising
- a contact mechanism portion disposed above an electromagnet portion, the contact mechanism portion having terminals including contact portions, the electromagnet portion being fixedly pressing engaged into a base, and each terminal of the contact mechanism portion being fixedly pressure-inserted into the base from above,
- wherein the contact portions of the terminals are inserted pressingly in a vertical direction at the side close to the elevational side plane of the electromagnet and are positioned on the side plane of the electromagnet, and
- wherein the terminals as a whole are formed to cover over the electromagnet from the side of the side plane of the electromagnet to the upper plane.
An electromagnetic relay comprising a box-shaped base with an opening portion provided therein sideways, an electromagnet portion for exposing the tip end portion of the yoke from the opening portion, a movable iron piece having an approximate L-shape in section with an inner side face angle portion being positioned in the tip end portion of the yoke, a hinge spring which has a pair of elastic arm portions cut, raised so as to oppose both the side portions, and also, has an elastic pawl portion cut, raised between the one pair of elastic arm portions, the engagement hole provided in the elastic arm portion being respectively engaged with the engagement projection provided on the outer side face of the opposing side wall of the base, the outer side face angle portion of the movable iron piece is depressed in the plate thickness direction by the elastic pawl portion to pivotally support the movable iron piece in a manner of hinge, characterized in that the relay of the present invention, a guide projection for guiding an elastic arm portion of the hinge spring is projected from the portion to be located near the opening portion among the outer side faces of the opposing side walls of the box-shaped base, and also, an inclination face is provided in at least either contact portion from between the elastic arm portion of the hinge spring and the engagement projection to come into contact when the hinge spring has been depressed along the guide projection.
An electromagnetic relay comprising a box-shaped base, wherein an opening portion is provided sideways, a pair of arm portions are provided with a drop groove are projected sideways from the upper portion of the edge portion end face for forming the opening portion, an electromagnet portion, wherein a coil is wound around a spool having a flange portion on both the end portions, an iron core is inserted into the central hole of the spool, a projecting one end portion is provided as a magnetic pole portion, while the projecting other end portion is secured to the vertical portion of a yoke having an approximate L-shape in section, and also, a pair of engagement pawl portions are projected from the lower portion on the outer side face of one flange portion, the one pair of engagement pawl portions are exposed sideways through the pressure insertion, the fixing in the axial direction of the iron core from the opening of the box-shaped base, a movable iron piece, wherein the shape is approximately L in section, the inner side face angle portion is pivotally positioned in the horizontal tip end portion of the yoke to be exposed from the opening portion of the box-shaped base, a hinge spring, wherein it is made of a leaf spring, the engagement arm portion projected sideways from the upper portion on both the sides is dropped from above into the drop groove of the box-shaped base to effect the engagement, and also, the engagement leg portion projected sideways from the lower portion on both the sides are engaged with the engagement pawl portion of the spool to bring the elastic pawl portion cut, raised from the central portion into pressure contact against the outer side angle portion of the movable iron piece to pivotally support it.
