Problems solved by technology

like Figure 4 , in order to ensure reliable rotation of the iron core 2.3, the width of the coil 2.4 inner cavity 2.4.2 of the coil 2.4 should be greater than the sum of the thickness of the iron core and its movement stroke. .2.3 The length is limited, so the ampere-turn value of the coil of this product is low, that is, the sensitivity is low

Embodiment Construction

[0017] Such as Figure 5 As shown, the embodiment of the present invention is composed of a base part 3, a magnetic circuit part 4 and a casing. The base part 3 at least includes a base 3.1, a moving spring part 3.2 and a static spring part 3.3. The magnetic circuit part 4 includes at least an armature part 4.1 and a coil part 4.2. The coil part 4.2 includes an iron core 4.2.1, a coil 4.2.2 and a magnetic isolation piece 4.2.3. The armature part 4.1 includes a magnetic steel 4.1.1, two armatures 4.1.2, and a pushing part 4.1.3. The magnetic steel 4.1.1 is located between the two armatures 4.1.2, and the pushing part 4.1.3 is located above the coil part 4.2 and the two side, does not occupy the length space of the coil 4.2.2. The armature 4.1.2, the magnetic steel 4.1.1 and the iron core 4.2.1 form a bridge type magnetic circuit. Such as Figure 6 As shown, the bridge magnetic circuit has 4 air gaps in total, two of which are equipped with magnetic isolation sheets 4.2.3 t...

Abstract

The invention discloses a polarization relay with high-sensibility, which is composed of chassis part, magnetic circuit part and case, wherein the chassis part contains chassis, active spring part and static spring part; the magnetic circuit part contains at least armature part, coil part and separating magnetic sheet; the coil part consists of iron core and coil; the armature part concludes magnetic steel, two armatures, pushing part with magnetic steel between two armatures; the armature, magnetic steel and iron core constitute bridge-typed magnetic circuit, whose two non-double-working air gaps load separating magnetic piece to form double-working air gap magnetic circuit; the armature part is divided into movement part of magnetic circuit, whose rotary shaft lies on the side of non-working gap.

Description

technical field [0001] The invention relates to a polarization relay with double working air gaps, in particular to the improvement of its sensitivity. Background technique [0002] Electromagnetic relay is an electromechanical component widely used in various household appliances, office equipment, and industrial control. With the continuous improvement of environmental awareness, polarized relays, as an energy-saving product, have been used more and more. In order to ensure the reliability of the product, it is required to have better sensitivity. [0003] Existing polarized relays with double working air gaps (see figure 1 ), the electromagnetic relay consists of a base part 1, a magnetic circuit part 2 and a casing. The base part 1 includes a base 1.1, a moving spring part 1.2, and a static spring part 1.3. The magnetic circuit part 2 includes two magnetic yokes 2.1, a magnetic steel 2.2, an iron core 2.3, a coil 2.4, a magnetic isolation sheet 2.5, and a push card 2...
