Abstract
The utility model discloses a small electromagnetic relay, comprising a casing and electromagnetic systems. The small electromagnetic relay is characterized in that two electromagnetic systems, with same direction, are arranged in the casing in parallel; an interior wall for mutually isolating the two electromagnetic systems is arranged on the casing; the electromagnetic systems comprises coil formers, bases, yoke irons, armatures, iron cores, movable contact springs, upper static contact springs and lower static contact springs; the upper static contact springs and lower static contact springs are fixed on the coil former; the movable contact springs rivet on the yoke irons; the movable contact springs rivet with the armature. The utility model not only shortens the space of the devices, and the two electromagnetic systems are not mutually interfered; that is to say, the small electromagnetic relay saves working space, time and labor, satisfies with clients, and is more reasonably applied to automobile circuits.
Description
Technical field
The utility model relates to a kind of miniature electro-magnetic relay.
Background technology
Miniature electro-magnetic relay is widely used in household electrical appliance, electronic equipment and the instrument and meter circuit.Existing miniature electro-magnetic relay comprises case, base and electromagnetic system, and wherein the structure of electromagnetic system is of all kinds, and is general all as far as possible little with volume, power is big as far as possible, sensitivity is high as far as possible, and cost is low as far as possible, and processing easy as far as possible is target.But, in some special application scenarios, especially in automobile circuit, the miniature electro-magnetic relay of same size is used in a large amount of concentrated areas, rational deployment how better, how in use more time saving and energy saving save space becomes the target that people pursue, and some clients also can propose some special instructions for uses.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of client's specific (special) requirements of can satisfying at above-mentioned prior art present situation, is applied to rational more miniature electro-magnetic relay in the automobile circuit.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of miniature electro-magnetic relay, comprise case and electromagnetic system, be set side by side with two described electromagnetic systems in the described case in the same way, described case is provided with the internal partition wall that two described electromagnetic systems are isolated mutually.
Described electromagnetic system comprises bobbin, base, yoke, armature, unshakable in one's determination, movable contact spring, last static contact and following static contact, described upward static contact and described static contact down are fixed on the described bobbin, described movable contact spring riveted and fixed is on described yoke, described movable contact spring riveted joint has armature, described iron core passes described bobbin, one end of described iron core and described yoke riveted and fixed, the pole shoe of the other end of described iron core is relative with described armature, be provided with enclosure wall around the described base medial surface, an end of the described yoke of described bobbin and described riveted joint unshakable in one's determination is arranged in the described enclosure wall.
End with described pole shoe of described bobbin is provided with the first contact spacing block and the second contact spacing block that one connects, the inside bottom of described first contact spacing block and the described second contact spacing block is provided with down the contact holddown groove, and described static contact is down pegged graft and is fixed in the described contact holddown groove down.
The lateral surface of the described second contact spacing block is provided with the contact holddown groove, and described upward static contact is pegged graft and is fixed on described going up in the contact holddown groove.
The lateral surface of described base can be provided with boss.
Above-mentioned electromagnetic system can use the change type circuit, also can use the bridge-type normally opened track circuit.
Compared with prior art, advantage of the present utility model is two identical electromagnetic systems are set up in parallel in the same way in a case, and internal partition wall is set in case, has not only dwindled the space of device, and can not crosstalk mutually again between two electromagnetic systems; After the boss that is arranged on base outer surface can make the relay assembling finish, between boss and case, form one around enclosed slot, be used to fill airtight and watertight padding; The utility model has been saved working space, and use is more time saving and energy saving, can satisfy client's special requirement, and it is also more reasonable to be applied in the automobile circuit.
