Abstract
The utility model discloses a small electromagnetic relay, which comprises a shell and two electromagnetic systems which are arranged in the shell parallely in the same direction, wherein the shell is provided with an inner clapboard which isolates the two electromagnetic systems with each other, and each electromagnetic system comprises a coil former, a base, yoke iron, armature iron, an iron core, a moving contact, an upper fixed contact and a lower fixed contact. The small electromagnetic relay is characterized in that the coil former is provided with a square iron core hole, the iron core is inserted in the iron core hole, and the iron core and the iron core hole are matched with each other. The small electromagnetic relay has the advantages that the coil former is provided with the square iron core hole, the iron core is inserted in the iron core hole, the shape of the iron core and the shape of the iron core hole are matched with each other, and the square iron core hole substitutes a round iron core hole, so that the small electromagnetic relay can reduce the width of the coil former, better save the installation space of the coil former, and further greatly reduces the volume of the relay formed by the two electromagnetic systems.
Description
Technical field
The utility model relates to a kind of relay, especially relates to a kind of miniature electro-magnetic relay.
Background technology
Along with the development of society, the purposes of relay more and more widely, and kind is also more and more, function also has nothing in common with each other.The patent No. is to disclose a kind of miniature electro-magnetic relay in the Chinese utility model specification of CN03210693.9, comprise case and electromagnetic system, characteristics are to be set side by side with two electromagnetic systems in the case in the same way, case is provided with the internal partition wall that two electromagnetic systems are isolated mutually, electromagnetic system comprises bobbin, base, yoke, armature, unshakable in one's determination, movable contact spring, last static contact and following static contact, last static contact and following static contact are fixed on the bobbin, the movable contact spring riveted and fixed is on yoke, the movable contact spring riveted joint has armature, though this structure has been dwindled the space of device, and can not crosstalk mutually again between two electromagnetic systems, it is also more time saving and energy saving to use when having saved working space, but because the hole unshakable in one's determination on the bobbin is circular, the width of bobbin is bigger, can not fully save the installing space of whole relay.
Summary of the invention
Technical problem to be solved in the utility model provides the miniature electro-magnetic relay that a kind of relay volume that dwindles the width of bobbin and two electromagnetic systems are constituted dwindles greatly.
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 two electromagnetic systems that are set up in parallel in the same way in described case, described case is provided with the internal partition 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 bobbin is provided with square hole unshakable in one's determination, described iron core is plugged in the described hole unshakable in one's determination, and described iron core and described hole unshakable in one's determination cooperatively interact.
The square cross-sectional shape in described hole unshakable in one's determination is made up of two parallel edges and two circular arcs.
Compared with prior art, the utility model has the advantages that because bobbin is provided with square hole unshakable in one's determination, iron core is plugged in the hole unshakable in one's determination, the shape unshakable in one's determination and the shape in hole unshakable in one's determination cooperatively interact, and substitute circular hole unshakable in one's determination with square hole unshakable in one's determination, can dwindle the width of bobbin, save the installing space of bobbin better, thereby dwindle the volume of the relay that constitutes by two electromagnetic systems greatly.
