Abstract
The utility model discloses a micro-miniature magnetic latching relay, which comprises an electromagnetic system and a set of contact system both arranged in a pedestal. The electromagnetic system comprises a magnetic steel assembly, and a coil assembly arranged on one side of the magnetic steel assembly and connected with a power supply. The contact system comprises an upper static contact connected with the spring plate arranged on a spring piece and connected with the spring piece, a lower static contact fixed on the pedestal through the spring piece, and a movable contact arranged on a pushing piece and connected with the pushing piece. The movable contact is arranged between the lower static contact and the upper static contact. The magnetic steel assembly is arranged below the lower static contact and is positioned corresponding to the contact system. According to the technical scheme of the utility model, the micro-miniature magnetic latching relay is closed only by means of a pulse excitation switch, thus being compact in structure, small in size, convenient to install and carry about, safe, reliable and long in service life.
Description
Technical field
The utility model relates to a kind of automatic control equipment in communication, security protection, small household appliances industry, particularly a kind of microminiature magnetic latching relay.
Background technology
Magnetic latching relay is a kind of new type of relay growing up in recent years, is actually a kind of " automatic switch " that with less electric current, remove to control larger electric current, in the device such as be widely used in electric power protection, automation, motion, remote control, measurement and communicate by letter.The same with other electromagnetic relays, circuit is played to automatic connection and cutting action.Difference is, the normally closed or normally open of magnetic latching relay is the effect that relies on permanent-magnet steel completely, and the conversion of its on off state has triggered by the pulse electrical signal of certain width.But existing magnetic latching relay security performance is general, easily damage.
Utility model content
The defect existing for existing magnetic latching relay, the utility model provides a kind of microminiature magnetic latching relay.
To achieve these goals, technical solution adopted in the utility model is:
A kind of microminiature magnetic latching relay, comprise the electromagnetic system and the one group of contact system that are arranged in pedestal, electromagnetic system comprises magnet steel combination and the coil combination that is arranged on magnet steel and combines a side and be connected with power supply, contact system comprises the upper fixed contact being connected on shell fragment, by shell fragment, be fixed on a lower fixed contact on pedestal and be connected to a moving contact on pushing piece, pushing piece is movably connected on pedestal by the mode of pegging graft, the upper end of pushing piece is fixed with shell fragment, the moving contact connecting on shell fragment be arranged between lower fixed contact and upper fixed contact and with lower fixed contact, the position that upper fixed contact is corresponding, magnet steel combination is arranged on the position corresponding with contact system, lower fixed contact below,
Described coil combination is unicoil or comprises set coil and the twin coil of resetting coil;
The material of described fixed contact, moving contact and upper fixed contact is silver alloy;
The material of described magnet steel combination is Nd Fe B alloys or aluminium nickel cobalt 32.
The beneficial effects of the utility model: only closed by pulse excitation switch; Compact conformation, volume is little, is convenient to install, carry; Safe and reliable, magnet steel is permanent-magnet steel, and the life-span is long.

Embodiment
A kind of microminiature magnetic latching relay, comprise the electromagnetic system and the one group of contact system that are arranged in pedestal 1, electromagnetic system comprises magnet steel combination 6 and the coil combination 7 that is arranged on magnet steel combination 6 one sides and is connected with power supply, contact system comprises the upper fixed contact 2 being connected on shell fragment, by shell fragment, be fixed on a lower fixed contact 4 on pedestal 1 and be connected to a moving contact 3 on pushing piece 5, pushing piece 5 is movably connected on pedestal 1 by the mode of pegging graft, the upper end of pushing piece 3 is fixedly connected with shell fragment, the moving contact 3 connecting on shell fragment be arranged between lower fixed contact 4 and upper fixed contact 2 and with lower fixed contact 4, the position of upper fixed contact 2 correspondences, magnet steel combination 6 is arranged on the position corresponding with contact system, lower fixed contact 4 belows, described coil combination 7 is for unicoil or comprise set coil and the twin coil of resetting coil, the material of described fixed contact 4, moving contact 3 and upper fixed contact 2 is silver alloy, the material of described magnet steel combination 6 is Nd Fe B alloys or aluminium nickel cobalt 32.
Operation principle of the present utility model: for every group of contact system, in coil combination, power up after (DC), under the effect in magnetic field, make magnet steel combination magnetization, absorption moving contact and upper fixed contact, make it to be connected with lower fixed contact, realizes the adhesive of this group contact system, after coil combination power-off, under the effect of remanent magnetism, still keep sucting state, guarantee the permanent adhesive of this group contact system; To coil combination, add suitable reverse current, eliminate the effect of remanent magnetism, relay discharges, and upper fixed contact and moving contact reset under the elastic reaction of shell fragment, and upper fixed contact, moving contact and lower fixed contact disconnect, and realizes the break function of this group contact system.
The beneficial effects of the utility model: only closed by pulse excitation switch; Compact conformation, volume is little, is convenient to install, carry; Safe and reliable, magnet steel is permanent-magnet steel, and the life-span is long.
The simple replacement of those ordinary skill in the art and replacing are all within this patent protection range.
