Relay armature

Abstract

The invention relates to a relay armature which comprises an armature body (1), a gap (2) and a gap (3). The gap (2) and the gap (3) are respectively arranged at two sides of the armature body (1) respectively. The relay armature is characterized in that closed angles (2.1, 2.2) at the root part of the armature gap (2) and closed angles (3.1, 3.2) at the root part of the armature gap (3) are arc angles. A largest distance between the closed angles (2.1, 2.2) at the root part of the armature gap (2) is larger than a distance between two parallel planes at the upper part of the gap (2). A largest distance between the closed angles (3.1, 3.2) at the root part of the armature gap (3) is larger than a distance between two parallel planes at the upper part of the gap (3). According to the relay armature, the assembly difficulty can be reduced, and the stability of the relay structure is raised.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to a relay armature. Background technique [0002] The relay is composed of iron core, coil, yoke, armature, spring, moving reed, static reed and other components. When the lead ends at both ends of the coil are energized, a certain current will flow through the coil, thereby generating an electromagnetic effect. The moving contact of the reed is attracted to the static contact of the static reed; after the coil is powered off, the magnetic field disappears, and the armature resets under the action of the spring, so that the moving contact of the moving reed is disconnected from the static contact of the static reed. open. Its working principle is to control the reciprocating movement of the armature through the magnetic circuit system, and then drive the opening and closing of the dynamic and static contacts by the armature, so as to realize the on-off control of the circuit.

Problems solved by technology

However, in the actual processing process, the closed angle at the top of the shoulder obtained by cutting often has a small amount of residual material, so that the closed angle is not a standard right angle, so that the shoulder of the yoke blade cannot be completely aligned with the "匚" shaped notch of the armature. Matching, increasing the difficulty of assembly

Moreover, when there is a lot of residual material at the closed corner at the top of the shoulder, the shoulder can only be partially accommodated in the gap, and the long-term reciprocating rotation of the armature may easily cause the armature to separate from the edge of the yoke, causing relay failure
