Relay armature limiting structure

Technical Field

The utility model belongs to the technical field of relay armature, specifically be a relay armature limit structure.

Background

Electromagnetic relays are generally composed of an iron core, a coil, an armature, a contact spring, and the like. As long as a certain voltage is applied to the two ends of the coil, a certain current flows in the coil, so that an electromagnetic effect is generated, the armature iron overcomes the pulling force of the return spring and is attracted to the iron core under the attraction effect of the electromagnetic force, and the movable contact of the armature iron is driven to be attracted with the fixed contact (normally open contact).

The armature part of relay can add the spring leaf between with external circular telegram contact for the convenience removes to and the stability of circuit switch-on, in order to guarantee flexible stable, but, because spring leaf itself is material elasticity, uses repeatedly for a long time, leads to material elasticity to disappear very easily, thereby causes the influence for the use of relay, so need add the structure of an supplementary spacing return in armature position.

Detailed Description

Referring to fig. 1 and 2, the relay armature limiting structure includes a base 1, a first connecting rod 11 is hinged on the base 1, a second connecting rod 12 is hinged on the first connecting rod 11, the first connecting rod 11 and the second connecting rod 12 are fixed through a spring 13, an armature 14 is hinged on the second connecting rod 12, a contact piece 15 is further arranged on the base 1, a spring piece 16 is arranged on the contact piece 15, the contact piece 15 and the spring piece 16 are both fixed with the base 1 through a first bolt 17, and the armature 14 is fixed with the spring piece 16.

Referring to fig. 1 and 2, the upper end of the armature 14 is of a conical structure, so as to be in contact with the iron core 4 and realize energization.

Referring to fig. 1, the spacers 2 are welded to both sides of the armature 14, the spacers 2 are connected to the spring plate 16 by the second bolt 21, and the spring plate 16 is made of elastic material and can be reset.

Referring to fig. 1, a housing 3 is disposed on a base 1, and a contact piece 15 penetrates through the housing 3 to realize the circuit connection of the whole relay.

Referring to fig. 1, the housing 3 is fixedly mounted with an iron core seat 31, and the iron core seat 31 is made of polyvinyl chloride material and has an insulating protection effect.
