Problems solved by technology

In the prior art, in the DC field of the relay, a block made of a hard magnetic material (that is, a permanent magnet, also called a magnetic steel) is usually used as an external magnetic field to realize arc extinguishing. The product formed by this structure has practical wiring features Polarity cannot be applied to the field of alternating current. In addition, the installation position of the magnetic steel needs to be set in the relay, so that the product volume becomes larger, and the miniaturization of the relay product volume cannot be achieved, and the cost also increases.

Embodiment 1

[0042] see Figure 3 to Figure 11As shown, an electromagnetic relay based on soft magnets to realize arc extinguishing according to the present invention includes a moving spring part 1, a static spring part 2, an armature part 3 and a push card 4; the moving spring part 1 includes a moving reed 11 and a moving reed The movable contact 12 that one end is connected; The static spring part 2 comprises the static contact 22 that one end of the static reed 21 and the static reed is connected, and the movable contact 12, the static contact 22 are in the position of matching; The pushing The card 4 is made of a soft magnetic material body 41 on one side and an insulating material body 42 on the other side. In this embodiment, the soft magnetic material body 41 is a magnetically conductive ferromagnetic material, specifically pure iron, and the insulating material body 42 is For plastics, of course, the soft magnetic material body can also be a metal material material with a high mel...

Embodiment 2

[0055] see Figure 12 Figure 13 As shown, an electromagnetic relay based on a soft magnetic body to realize arc extinguishing according to the present invention is different from Embodiment 1 in that the soft magnetic material body 41 and the insulating material body 42 are connected in different ways. In this embodiment, the The first clamping part is arranged at one end of the soft magnetic material body 41, and the other end of the soft magnetic material body is provided with a first riveting part that is provided with a riveting hole 417, and the second clamping part is arranged at one end of the insulating material body 42 , the other end of the insulating material body is provided with a second riveting portion, that is, a riveting hole 422, and the soft magnetic material body 41 and the insulating material body 42 are riveted through the first riveting portion and the second riveting portion. They are fixedly connected to form an integral part, that is, the rivet hole...

Embodiment 3

[0057] see Figure 14 Figure 15 As shown, an electromagnetic relay based on soft magnets to realize arc extinguishing according to the present invention is different from Embodiment 1 in that the slot 418 between the first push arm 411 and the second push arm 413 is open on one side, It is suitable for snapping in the moving reed 11 from one side.

Abstract

The invention discloses an electromagnetic relay for realizing arc extinguishing based on a soft magnet. The electromagnetic relay comprises a movable spring part, a static spring part, an armature part and a push card. A movable push card is composed of a soft magnetic material body on one side and an insulating material body on the other side. The soft magnetic material body of the push card isprovided with a first clamping portion which is cooperated with a movable spring sheet in a clamping manner. The insulating material body of the push card is clamped and cooperated with the armature part. One end head of the soft magnetic material body of the push card is correspondingly arranged on a side edge where a movable contact is cooperated with a static contact, and a projection of one end head of the soft magnetic material body at the movable contact and the static contact at least covers a part of gap between the movable contact and the static contact when the contacts are disconnected. According to the above structure, arc extinguishing can be achieved, meanwhile, there is no polarity requirement for wiring of the relay, and a defect that a size of a relay product is increaseddue to the fact that an installation position of magnetic steel needs to be set in the prior art can be overcome.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to an electromagnetic relay for realizing arc extinguishing based on soft magnets. Background technique [0002] The relay is an electronic control device, which has a control system (also known as the input circuit) and a controlled system (also known as the output circuit), usually used in automatic control circuits, it actually uses a smaller current to control a larger An "automatic switch" of electric current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit. [0003] When the moving contact (moving contact) and the static contact (static contact) in the relay and other switching appliances are disconnected, an arc is usually generated. It is common to use an external magnetic field to push the arc to the arc extinguishing chamber to realize forced arc extinguishing. arc means. In the prior art, in the DC field of ...
