Abstract
The utility model discloses a PCB type low-power magnetic latching relay, which comprises an electromagnetic system and a contact system both arranged inside a pedestal (1). The electromagnetic system comprises magnetic steel (6) and a combined coil (7) arranged on the two sides of the magnetic steel (6). The combined coil (7) is connected with a power supply through a PCB. The contact system comprises an upper static contact (2) arranged on a spring piece and connected with the spring piece, a lower static contact (4) fixed on the pedestal (1), and a movable contact (3) arranged on an elastic pushing piece (5) and connected with the elastic pushing piece (5). The upper static contact (2), the movable contact (3), the lower static contact (4) and the magnetic steel (6) are in linear arrangement sequentially from top to bottom. According to the technical scheme of the utility model, the PCB type low-power magnetic latching relay can be closed only by means of a pulse excitation switch. The PCB type low-power magnetic latching relay has the advantages of small size, convenient installation, portability, low power consumption, safety, reliability and long service life.
Description
Technical field
The utility model relates to a kind of automatic control switch in circuit control field, particularly a kind of PCB formula small-power 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 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 control switch, the utility model provides a kind of PCB formula small-power magnetic latching relay.
To achieve these goals, technical solution adopted in the utility model is:
A kind of PCB formula small-power magnetic latching relay, comprise the electromagnetic system and the contact system that are arranged in pedestal, electromagnetic system comprises magnet steel and is arranged on the built-up coil of magnet steel both sides, built-up coil is connected with power supply by PCB, contact system comprises the upper fixed contact that is connected on shell fragment, is fixed on the lower fixed contact on pedestal and is connected to the moving contact on resiliency urged sheet, pushing piece is movably connected on pedestal by the mode of pegging graft, and upper fixed contact, moving contact, lower fixed contact and magnet steel are from top to bottom arranged in a linear successively;
Described built-up coil is unicoil or the twin coil for comprising set coil and resetting coil;
The material of described upper fixed contact, moving contact and lower fixed contact is silver alloy;
The material of described magnet steel is Nd Fe B alloys or aluminium nickel cobalt 32.
The beneficial effects of the utility model: only closed by pulse excitation switch; Adopt PCB formula to install, volume is little, is convenient to install, carry; Low in energy consumption, load capacity is strong; Safe and reliable, magnet steel is permanent-magnet steel, and the life-span is long.

Fig. 1, generalized section of the present utility model;
Fig. 2, overall structure schematic diagram of the present utility model.
Embodiment
A kind of PCB formula small-power magnetic latching relay, comprise the electromagnetic system and the contact system that are arranged in pedestal 1, electromagnetic system comprises magnet steel 6 and is arranged on the built-up coil 7 of magnet steel 6 both sides, built-up coil 7 is connected with power supply by PCB, contact system comprises the upper fixed contact 2 that is connected on shell fragment, is fixed on the lower fixed contact 4 on pedestal 1 and is connected to the moving contact 3 on resiliency urged sheet 5, pushing piece 5 is movably connected on pedestal 1 by the mode of pegging graft, and upper fixed contact 2, moving contact 3, lower fixed contact 4 and magnet steel 6 are from top to bottom arranged in a linear successively; Described built-up coil 7 is unicoil or the twin coil for comprising set coil and resetting coil; The material of described upper fixed contact 2, moving contact 3 and lower fixed contact 4 is silver alloy; The material of described magnet steel 6 is Nd Fe B alloys or aluminium nickel cobalt 32.
Operation principle of the present utility model: power up after (DC) at built-up coil, under the effect in magnetic field, make magnet steel magnetization, absorption moving contact and upper fixed contact, make it to be connected with lower fixed contact, switch adhesive, after built-up coil power-off, under the effect of remanent magnetism, still keep sucting state, guarantee permanent adhesive; 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 switch.
The beneficial effects of the utility model: only closed by pulse excitation switch; Adopt PCB formula to install, volume is little, is convenient to install, carry; Low in energy consumption, load capacity is strong; 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.
