Problems solved by technology

Furthermore, when the fine powder adheres to the surface of the contact, the problems mentioned above will occur
[0005] And, in order to improve the contact reliability of the contact, also consider the method of increasing the number of poles of the contact (making the contact open and close in a many-to-many mode), but in this method, the occupied space of the contact opening and closing mechanism increases, and there are Problems leading to device enlargement

Abstract

An aspect of the invention provides a compact contact switch structure having high contact reliability of a contact. A movable contact (44) is opened and closed with respect to a fixed contact (39) disposed in an opposite position by operating a movable touch piece (38) provided with the movable contact. The contact switch structure includes a guide unit that is provided in a side region of the movable touch piece to control an air flow in an operating range of the movable touch piece.

Description

technical field [0001] The present invention relates to a contact opening and closing structure and an electromagnetic relay provided with the contact opening and closing structure. Background technique [0002] In the past, as an electromagnetic relay, for example, the following technologies are known: exciting or demagnetizing an exciting coil arranged around a fixed iron core, causing the fixed iron core to attract or separate from the armature, operating a movable contact piece mounted on the armature, and making the A movable contact of the movable contact piece and a fixed contact arranged at a position facing the movable contact are opened and closed. [0003] However, in the above-mentioned electromagnetic relay, burrs, burrs, or fine debris may be attached when the components such as the armature and the field coil are processed, and these parts will float as fine powder (about 20 μm in diameter) later. When the fine powder adheres to the surface of the contact, th...
