Each contact system comprises a fixed contact (5) connected onto the pedestal (1) and a moving contact (4) capable of completing contact opening-closing together with the fixed contact (5). The moving contact (4) is arranged on a moving pieces combination (3). One end of the moving piece combination (3) is fixed on the pedestal while the other end of the moving piece combination (3) is connected with a pushing piece (6). The end, connected with the pushing piece (6), of the moving piece combination (3) can move leftwards and rightwards. The beneficial effects of the utility model reside in that the double-set magnetic latching relay saves the cost and has a simple structure; and the double-set magnetic latching relay is safe and reliable, and is long in life.
Description
Technical field
The utility model relates to a kind of automatic control equipment in electronic instrument field, particularly a kind of two set magnetic latching relay.
Background technology
Magnetic latching relay is a kind of new type of relay growing up in recent years, is actually with less electric current and goes to control the one " automatic switch " of 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 function ratio is more single, a magnetic latching relay conventionally can only be realized the closed of place's circuit or disconnect, and disconnects if need to realize closed another place of a place, need to connect two magnetic latching relays; And existing magnetic latching relay production cost is higher, finished product is expensive.
Utility model content
The defect existing for existing magnetic latching relay, the utility model provides a kind of two set magnetic latching relay.
To achieve these goals, technical solution adopted in the utility model is:
A kind of two set magnetic latching relay, comprise the electromagnetic system and the two groups of contact systems that are arranged in pedestal, electromagnetic system comprises magnet steel combination and coil combination, magnet steel combination is arranged on the one end that is connected with several leading-out terminals on pedestal, the coil combination being connected with power supply is arranged on the other end of pedestal, two groups of contact systems are separately positioned on the left and right sides of magnet steel combination, every group of contact system comprises that fixed contact being connected on pedestal and one can complete the moving contact that contact opens and closes with fixed contact, moving contact is arranged in moving plate combination, one end of moving plate combination is fixed on pedestal, the other end of moving plate combination is connected with pushing piece, it is can left and right movable that moving plate combines one end of being connected with pushing piece,
Described moving plate combines the one end being connected with pushing piece and is connected to by shell fragment or jump ring in the draw-in groove arranging on pushing piece;
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 lower 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: can independently control the closed and disconnected of every group of contact system, use a relay to realize a disconnection, a closed function that two relays just can reach, cost-saving; Only by pulse excitation switch closure; Simple in structure, production cost is little; Safe and reliable, magnet steel is permanent-magnet steel, and the life-span is long.

Embodiment
A kind of two set magnetic latching relay, comprise the electromagnetic system and the two groups of contact systems that are arranged in pedestal 1, electromagnetic system comprises magnet steel combination 7 and coil combination 2, magnet steel combination 7 is arranged on the one end that is connected with several leading-out terminals 8 on pedestal 1, the coil combination 2 being connected with power supply is arranged on the other end of pedestal 1, two groups of contact systems are separately positioned on the left and right sides of magnet steel combination 7, every group of contact system comprises that fixed contact 5 being connected on pedestal 1 and one can complete the moving contact 4 that contact opens and closes with fixed contact 5, moving contact 4 is arranged in moving plate combination 3, one end of moving plate combination 3 is fixed on pedestal 1, the other end of moving plate combination 3 is connected with pushing piece 6, moving plate combination 3 one end that are connected with pushing piece 6 can left and right activity, described moving plate combination 3 one end that are connected with pushing piece 6 are connected to by shell fragment or jump ring in the draw-in groove arranging on pushing piece 6, described coil combination 2 is for unicoil or comprise set coil and the twin coil of resetting coil, the material of described fixed contact 6, moving contact 5 and lower fixed contact 4 is silver alloy, the material of described magnet steel combination 7 is Nd Fe B alloys or aluminium nickel cobalt 32.
Operation principle of the present utility model: for every group of contact system, power up in coil combination 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, when after coil combination power-off, under the effect of remanent magnetism, still keep sucting state, ensure the permanent adhesive of this group contact system; Add suitable reverse current to coil combination, 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: can independently control the closed and disconnected of every group of contact system, use a relay to realize a disconnection, a closed function that two relays just can reach, cost-saving; Only by pulse excitation switch closure; Simple in structure, production cost is little; 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.
