Abstract

The invention relates to a clapper-type relay which comprises an electromagnetic assembly and a contact assembly, the electromagnetic assembly comprises a yoke and an armature, the contact assembly comprises a movable reed, a wire inlet pin and a wire outlet pin, the wire outlet pin is provided with a static contact I and a static contact II, and the static contact I and the static contact II are arranged on the movable reed. A movable contact I is arranged at the position, corresponding to the fixed contact I, of the movable reed, a movable contact II is arranged at the position, corresponding to the fixed contact II, of the movable reed, the fixed contact I and the movable contact I are made of tungsten materials, and the fixed contact II and the movable contact II are made of silver materials. By adopting the technical scheme, the clapper type relay provided by the invention adopts a clapper type structure to realize opening and closing of the movable contact and the static contact, so that the movable contact and the static contact made of the tungsten material are contacted firstly, the movable contact and the static contact made of the silver material are contacted later, the movable contact and the static contact made of the tungsten material are disconnected firstly, and the movable contact and the static contact made of the silver material are disconnected later; a double-breakpoint output function and impact resistance are realized, and the service life of the contact is prolonged.

Description

technical field [0001] The invention relates to a relay, in particular to a snap-in relay. Background technique [0002] The preheating relays on the market usually control the preheating of the whole vehicle with low voltage and low current. The internal contacts of the preheating relays are all output in a "bridge" connection. The defect is that the maximum carrying current is 100A. In addition, silver static contacts are used on the incoming and outgoing pins, and silver moving contacts are set on the moving reed. When a certain voltage is applied to both ends of the coil, the two sets of moving and static contacts are closed and disconnected at the same time. A current path is formed between pins, static contacts, moving contacts, and outgoing pins. However, when the above-mentioned relay passes through a large current, it generates extremely serious heat, consumes a large amount of silver contact surface, and ages quickly, which shortens the life of the relay. Conten...
