Abstract
A relay with long service life and high sensitivity consists of an electromagnetic mechanism, a contact system and an outer casing. The electromagnetic mechanism includes a coil, a yoke, an iron core, a stent and a keeper. The contact system includes a pedestal combination, the combination of a static contact plate and a movable contact plate, an excessive lead wire and an insulation plate. The movable contact plate combination is provided with the movable contact plate and a buffer strip. A hard contact structure is adopted for the static contact plate. The half-flexible contact is formed between the movable and the static contact plates which are all made from pallas. The relay has the advantages of long service life and high sensitivity.
Description
One, technical field
The utility model belongs to the relay technical field, relates in particular to a kind of long-life supersensitive relay.
Two, background technology
The internal structure of relay is generally by contact system, electromagnetic system be configured to, the general flexibility that adopts of the contact system part of traditional relay contacts, what reed adopted is silver-magnesium-nickel alloys, the power consumption of coil is bigger, reliability and sensitivity are lower, and the life-span is shorter, and the work number of times has only 100,000 times.At above-mentioned shortcoming, the utility model has reached and has improved the life-span of relay and the purpose of sensitivity by traditional relay contact system and electromagnetic mechanism are improved innovation.
Three, summary of the invention
The purpose of this utility model has provided a kind of long-life type supersensitive relay, improves the life-span and the sensitivity of relay.In order to reach this purpose, the relay contact system contact spring is adopted the half flexible way of contact; Wherein moving contacting plate adopts the supporting spring transition to be connected with leg; Quiet contact chip adopts " firmly " contact structures; The moving contacting plate of contact system and the material of quiet contact chip all adopt pallas simultaneously, thereby have improved the life-span of relay, and its work number of times is brought up to 1,000,000 times.This relay electromagnetic mechanism has adopted the balanced armature rotary structure, and the resistance value of coil is improved, and at the product of rated voltage 5V specification, coil resistance is brought up to 300 ohm, improves 10 times than the conventional products with volume.Thereby reduce power consumption (with volume conventional products power consumption is 0.69W, and the power consumption of the utility model product is less than 0.25W), reached the purpose that improves its sensitivity.
Adopt the beneficial effect of the technical program to be: the life-span, the work number of times that have prolonged relay reach minimum 1,000,000 times; Reducing power consumption greatly improves the sensitivity of relay.
