Abstract
The utility model discloses an AC electromagnetic relay, which is composed of a magnetic path portion and a contact portion, wherein, the magnetic path portion is composed of an iron core, an armature, yoke iron, a short circuit ring, a coil, a tension spring, etc. The AC electromagnetic relay is characterized in that a side plate which is sheathed on the iron core is arranged between the coil and the yoke iron, and contact among the side plate, the iron core, and the yoke iron is favorable. Since the utility model increases one side plate made of pure copper on the basis of the original relay, the side plate can conduct the short circuit to magnetic leakage in an electromagnetic system; eddy current loss can be reduced; AC epilogue of the coil of the relay can be greatly lowered in the process of overload; interference of the relay on other electronic devices can be reduced, and contact reliability of contacts can be increased.
Description
The utility model relates to relay, especially relates to a kind of alternating current electromagnetic relay.
Alternating current electromagnetic relay generally all is made up of magnetic circuit part, contact portion, wherein the magnetic circuit part is made up of iron core, armature, yoke, short-circuited conducting sleeve, coil, bobbin and extension spring, the relay technical process of this structure requires quite high, the induction reactance that relay has just moved is also very big, and the interchange coda of relay coil overload during promptly greater than 1.2 times of rated values is very big, huge like this interchange coda can produce bigger interference to other electronic equipments, cause the relay contact contact unreliable, burn out the contact easily, and cause the subsequent conditioning circuit misoperation or be failure to actuate.
The purpose of this utility model be to provide a kind of can significantly reduce the relay coil overload time the interchange coda, reduce interference, improve the alternating current electromagnetic relay of the contact reliability of contact other electronic equipment.
The purpose of this utility model is achieved in that the utility model is made up of magnetic circuit part, contact portion, wherein the magnetic circuit part is made up of iron core, armature, yoke, short-circuited conducting sleeve, coil, bobbin and extension spring, contact portion is made up of movable contact spring, reed group, moving contact, fixed contact, movable contact spring pin, static contact spring piece pin, coil pin, lead, base, cover plate, feature is that the side plate that is enclosed within on the iron core is installed between coil and the yoke, and side plate contacts well with iron core, yoke.
Short-circuited conducting sleeve, iron core and side plate constitute I-shaped.
The utility model is owing to increase the side plate that fine copper is made on the basis of original relay, side plate is installed between coil and the yoke, and be enclosed within on the iron core, and side plate contacts well with iron core, yoke, short-circuited conducting sleeve, iron core and side plate constitute I-shaped, side plate just can carry out short circuit to the leakage field in the electromagnetic system like this, reduced the eddy current loss in the magnetic circuit system, interchange coda when significantly having reduced the relay coil overload, reduced the interference of relay, improved the contact reliability of contact other electronic equipment.According to test, the utility model does not have the interchange coda when the overload of 3 times of rated values of load.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the magnetic circuit system generalized section.
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.
The utility model is made up of magnetic circuit part, contact portion, wherein the magnetic circuit part is made up of iron core 14, armature 8, yoke 11, short-circuited conducting sleeve 6, bobbin 7, coil 13 and extension spring 10, contact portion is made up of movable contact spring 5, reed group 18, moving contact 2, fixed contact 4, movable contact spring pin 16, static contact spring piece pin 1, coil pin 15, lead 9, base 3, cover plate 17, the side plate of being made by fine copper 12 that is enclosed within on the iron core 14 is installed between coil 13 and yoke 11, short-circuited conducting sleeve 6, iron core 14 and side plate 12 constitute I-shaped, and side plate 12 contacts well with iron core 14, yoke 11.
