Embodiment 1

[0084] Example 1 is an example in which the direction and strength of the lines of magnetic force when the first and second permanent magnets 30 and 32 and the auxiliary yoke 31 are combined are analyzed.

[0085] As a result of the analysis, through the vector line ( Figure 14 ) shows the direction of the magnetic lines of force, and, by shading ( Figure 15 ) shows the strength of the magnetic field lines.

Embodiment 2

[0087] Example 2 is an example in which the direction and strength of the lines of magnetic force are analyzed in a case where it is arranged in the same manner as in Example 1 above except that the auxiliary yoke 31 is not provided.

[0088] As a result of the analysis, through the vector line ( Figure 16 ) shows the direction of the magnetic lines of force, and, by shading ( Figure 17 ) shows the strength of the magnetic field lines.

[0089] by right Figure 14 , Figure 15 with Figure 16 , Figure 17 By comparison, it was confirmed that the direction of the lines of force of the permanent magnets and the distribution of the intensity of lines of force of the permanent magnets are changed by providing the auxiliary yoke 31 .

[0090] Additionally, according to Figure 14 , Figure 15 It can be confirmed how and to what extent the lines of force of the first and second permanent magnets 30 and 32 act between the fixed contacts 21a to 24a and the movable contacts 86...

Abstract

The invention provides an electromagnetic relay with high insulation. Therefore, the electromagnetic relay is configured to include: a base (10); an electromagnet block (40), which is arranged on the upper surface of the base (10), and is provided with a reel (41) having a through hole opened from a flange portion (42). ); movable iron sheet (60), which rotates based on the excitation and non-excitation of the electromagnet block (40); the movable contact piece, which rotates integrally with the movable iron sheet (60); movable contact (87a), which is fixed to the free end of the movable contact piece; fixed contact (23a), which is fixed to the fixed contact terminal (23), and moves with the rotation of the movable contact piece It is arranged so as to contact and separate from the movable contact (87a). In particular, ribs (72, 46) for insulation are protruded from the inner surface of the spacer (70) integrated with the movable iron piece (60) and the outer surface of the flange portion (41), respectively, to A straight line connecting the magnetic pole portion (53), which is one end portion of the iron core protruding from the through hole, and the fixed contact (23a) or the fixed contact terminal (23) at the shortest distance is blocked.

Description

technical field [0001] The present invention relates to an electromagnetic relay, and particularly to an electromagnetic relay having an insulating structure with high insulation properties. Background technique [0002] At present, as an electromagnetic relay, for example, there is a relay having a terminal connection structure of an electrical device composed of an external terminal having an electrical connection portion protruding from the upper surface of a base and a relay terminal having a conductive The flexible elastic plate-shaped body is bent into a substantially U-shape, and is press-fitted into the concave part of the internal components of the above-mentioned base body, and is electrically connected with the internal components. Press the electrical connection part of the above-mentioned external terminal. [0003] In particular, the above-mentioned electromagnetic relay has a terminal connection structure of an electric device, and is characterized in that it...
