Description
Technical field
The utility model relates to a kind of automatic control equipment in electronic instrument field, particularly two groups of Transformational magnetic latching relays of PCB formula.
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 function ratio is more single, a magnetic latching relay conventionally can only be realized the closed of place's circuit or disconnect, if need to realize closed another place, a place, disconnects, and need to connect two magnetic latching relays; And the volume of existing magnetic latching relay is larger, inconvenience is installed in mini-plant, and security performance is general, easily damage.
Utility model content
The defect existing for existing magnetic latching relay, the utility model provides PCB formula two groups of Transformational magnetic latching relays.
To achieve these goals, technical solution adopted in the utility model is:
Two groups of Transformational magnetic latching relays of PCB formula, comprise the electromagnetic system and the two groups of contact systems that are arranged in pedestal, electromagnetic system comprises magnet steel combination and is arranged on the built-up coil of magnet steel combination both sides, built-up coil is connected with power supply by PCB, every group of contact system comprises the upper fixed contact being connected on 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, on pushing piece, be fixedly connected with two shell fragments, two moving contacts are separately positioned on two shell fragments, lower fixed contact in magnet steel combination and every group of contact system, moving contact and upper fixed contact be line correspondence arrangement successively from the bottom to top,
Described built-up coil is the twin coil that comprises set coil and resetting coil;
Described two groups of contact systems be arranged in parallel, and the upper fixed contact in two groups of contact systems, moving contact and lower fixed contact are positioned at three planes from top to bottom successively;
The material of described upper 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 by PCB, use a relay to realize a disconnection, a closed function that two relays just can reach, cost-saving; Only closed by pulse excitation switch; Adopt PCB formula to install, volume is little, is convenient to install, carry; Safe and reliable, magnet steel is permanent-magnet steel, and the life-span is long.

Embodiment
Two groups of Transformational magnetic latching relays of PCB formula, comprise the electromagnetic system and the two groups of contact systems that are arranged in pedestal 7, electromagnetic system comprises magnet steel combination 2 and is arranged on the built-up coil 1 that magnet steel combines 2 both sides, built-up coil 1 is connected with power supply by PCB, every group of contact system comprises the upper fixed contact 6 being connected on shell fragment, be fixed on a lower fixed contact 4 on pedestal 7 and be connected to a moving contact 5 on pushing piece 3, pushing piece 3 is movably connected on pedestal 7 by the mode of pegging graft, on pushing piece 3, be fixedly connected with two shell fragments, two moving contacts 5 are separately positioned on two shell fragments, lower fixed contact 4 in magnet steel combination 2 and every group of contact system, moving contact 5 and upper fixed contact 6 be line correspondence arrangement successively from the bottom to top, the twin coil of described built-up coil 1 for comprising set coil and resetting coil, described two groups of contact systems be arranged in parallel, and the upper fixed contact 6 in two groups of contact systems, moving contact 5 and lower fixed contact 4 are positioned at three planes from top to bottom successively, the material of described upper fixed contact 6, moving contact 5 and lower fixed contact 4 is silver alloy, the material of described magnet steel combination 2 is Nd Fe B alloys or aluminium nickel cobalt 32.
Operation principle of the present utility model: for every group of contact system, at built-up coil, 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 built-up coil power-off, under the effect of remanent magnetism, still keep sucting state, guarantee the permanent adhesive of this group contact system; To built-up coil, 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: can independently control the closed and disconnected of every group of contact system by PCB, use a relay to realize a disconnection, a closed function that two relays just can reach, cost-saving; Only closed by pulse excitation switch; Adopt PCB formula to install, volume is little, is convenient to install, carry; Safe and reliable, magnet steel is permanent-magnet steel, and the life-span is long.
