Problems solved by technology

If you want to increase the current-carrying area by increasing the width of the dynamic and static spring leads, you will inevitably need to increase parts or volume, etc., which is not only not conducive to miniaturization design, but also leads to an increase in parts, making the structure complex and not conducive to automatic assembly. and many more

Abstract

The invention provides an electromagnetic relay, which comprises a base, a coil frame, an electromagnetic system and a contact system, and is characterized in that the coil frame is assembled on the base, the electromagnetic system comprises an armature, and the contact system comprises a movable spring and a static spring; the coil rack comprises a first flange, a second flange and a winding shaft; the static spring is provided with a static spring fixing part corresponding to the first flange, the armature is arranged corresponding to the first flange, the movable spring is fixed on the armature, and a movable contact on the movable spring corresponds to a static contact on the static spring fixing part to form a contact group; the first flange of the coil rack is further provided with a stopping part in a protruding mode, the stopping part and the armature are not overlapped with the static spring fixing part in position on the projection surface projected to the base, the armature extends to form a stopping foot, and limiting is achieved by inserting the stopping foot into the stopping part. The current-carrying capacity can be improved under the condition that the size is kept unchanged, and therefore the effects of miniaturization and large current carrying are achieved.

Description

technical field [0001] The invention relates to the field of relays, in particular to an electromagnetic relay. Background technique [0002] The current-carrying capacity of existing electromagnetic relay products is limited due to product volume, which cannot meet the needs of customers. The existing electromagnetic relay product structure is shown in the publication number CN202008961U and the name is a normally open electromagnetic relay with a coil frame limit; in this document, in order to limit the movement of the armature, a There is a card slot, the armature is confined in the card slot, as in the document figure 1 As shown, the slot is on the same side as the contacts. If you want to increase the current-carrying area by increasing the width of the dynamic and static spring leads, you will inevitably need to increase parts or volume, etc., which is not only not conducive to miniaturization design, but also leads to an increase in parts, making the structure compl...
