Abstract
The utility model discloses a magnetic latching relay. The magnetic latching relay comprises a base, a coil combination, a magnetic steel combination, a promotion sheet, a clamping plate, a spring, a moving sheet combination, a static sheet combination and a top cover, wherein the coil combination comprises a coil holder, terminal pins, excitation coil and yoke irons, the magnetic steel combination comprises armatures, a magnet and a magnetic steel insulator, the base is provided with a mounting hole for the magnetic steel combination, the mounting hole is elliptical, and a long shaft of the elliptical mounting hole is perpendicular between the two yoke irons. According to the magnetic latching relay, the base, the mounting hole for the magnetic steel combination, and a clamping plate hole are designed to be elliptical, and the long shaft of the elliptical mounting hole is perpendicular between the two yoke irons, a gap is generated between the hole and the shaft during commutation work of a magnetic steel of the relay to make the left and right yoke irons be automatically picked up to a proper position, so commutation force of the magnetic steel, electromagnetic latching force and integral performance are improved.
Description
Technical field
Utility model relates to and is applied in the national grid electric-power metering, automatically controls a kind of magnetic latching relay on the various automation fields such as smart card meter and illumination.
Background technology
Relay is a kind of electronic control device, be widely used in electric power protection, automation, motion, remote control, measurement and the device such as communicate by letter in.It is actually a kind of " automatic switch " that removes to control larger electric current with less electric current.Therefore play the effects such as automatic adjusting, safeguard protection, change-over circuit in circuit, for satisfying various specific (special) requirements, the unfailing performance of necessary reinforcing relay.Existing magnetic latching relay ubiquity makes magnet steel armature shown in Figure 2 and yoke pole shoe adhesive (excesssive gap not in place due to processing and assembly error, the subsides injustice) phenomenon, make the reversing force of relay magnet steel reduce and lose the magnetic force confining force, the useful life that has a strong impact on the relay integral performance parameter and reduced relay.
Owing to scale error occurring unavoidably in producing armature and yoke process, add assembly error, the mounting center axle of magnet steel is again that gapless coordinates with pedestal installing hole and clamping plate installing hole simultaneously, it is not in place that therefore left yoke magnetic pole and left armature or right armature and the adhesive of right yoke magnetic pole can appear in the relay real work, produce very large gap, have a strong impact on the reversing force of magnet steel, caused relay to lose the electromagnetism confining force.Thereby affect relay integral performance parameter and normal the use.
The utility model content
The utility model purpose is to provide a kind of magnetic latching relay for the defective that prior art exists.
The utility model adopts following technical scheme for achieving the above object:
The utility model magnetic latching relay comprises that pedestal, coil combination, magnet steel combination, pushing piece, clamping plate, spring, moving plate combination, still combination and upper cover form, and coil combination is made of coil holder, terminal pin, magnet exciting coil and yoke; The magnet steel combination is comprised of armature, magnet and magnet steel insulator, and described pedestal is provided with magnet steel combination installing hole, and described installing hole is oval, and the major axis axle of oval installing hole is perpendicular between two yokes.
The utility model is designed to ellipse with pedestal and magnet steel combination installing hole and plywood hole, its oval major axis vertical with two yokes between, at the commutation work mesopore of relay magnet steel also axle generation gap, left and right armature and left and right yoke automatic pick are put in place.Improve magnet steel reversing force, electromagnetism confining force and overall performance.

Embodiment
As depicted in figs. 1 and 2, a kind of magnetic latching relay of the utility model comprises pedestal 1, coil combination 2, and magnet steel combination 3, moving plate combination 7, still combination 8, pushing piece 4, spring 6, clamping plate 5 and upper cover 9 form.Pedestal 1 is provided with magnet steel combination installing hole; Coil combination 2 is by coil holder 12, magnet exciting coil 11, and yoke 13 and terminal pin 10 form; Magnet steel combination 3 is by magnet 15, and armature 14 and magnet steel insulator 16 form.
The mutual adhesive of yoke 13 in armature 14 in magnet steel combination and coil combination and produce relay contact state confining force.The operation principle of magnetic circuit part is: apply enough pulse voltage to coil, the magnetic flux that coil produces is by unshakable in one's determination, and---------the right yoke magnetic pole of magnet steel---right armature---forms the closed-loop path to left armature to left yoke magnetic pole, produces suction at armature and yoke interpolar.The adjutage of magnet steel makes dynamic and static tactile closure and produces enough pressure, reliably current-carrying by 4 pairs of movable contact spring 6 applied thrusts of pushing piece.
