Background technology

Existing 1/2 Crystal Can Relay electromagnetic system mostly is the balanced rotary structure, and this structure adopts double-acting air gap, and magnetic resistance is large, and electromagnetic efficiency is low; Restore counter-force and adopt torsion spring, return spring form to provide more, easily produce resonance, product anti-vibration, impact capacity are poor, cause contact reliability not high.

The utility model content

The technical problem that the utility model solves: design a kind of 1/2 Crystal Can Relay electromagnetic system, adopt equilibrant force formula electromagnetic structure, with permanent-magnet steel as restoring means, when release condition, permanent-magnet steel in the magnetic circuit to the confining force of armature and pole-face unshakable in one's determination when the attracting state to the electromagnetic attraction of armature about equally, the pull characteristics of relay and spring load characteristic symmetrical balance, and adopt the push rod form to realize the contact conversion of contact system, electromagnetic efficiency is high, compact conformation, anti-vibration, impact capacity are strong, and contact reliability is high.

Technical solution of the present utility model: a kind of 1/2 Crystal Can Relay electromagnetic system, by cover plate, support, armature, coil, unshakable in one's determination, magnet steel, vertical shaft, the yoke I, the yoke II, the yoke III forms, described yoke I, the yoke II, the yoke III is fixed between support and the cover plate, and yoke I, be fixed with iron core between the yoke II, be set with coil on the iron core, the yoke II, be fixed with magnet steel between the yoke III, armature is installed between support and the cover plate by vertical shaft and is positioned at the place ahead of coil, and yoke III front end has inside flexure plane, and the armature right-hand member is curved inwardly between the face at yoke II front end face and yoke III front end.

The right-hand member of the described armature outside is shaped with the inclined-plane, and flexure plane applying in inclined-plane and yoke III front end when static.

The outside of described yoke I is fixed with the damping reed, and the cantilever end of damping reed is fitted in the left end of armature.

The two ends, the left and right sides of described armature are fixed with push rod I, push rod II.

The advantage that the utility model compared with prior art has and effect:

1, the utility model adopts equilibrant force formula electromagnetic structure, compact conformation, and shock resistance, vibration ability are strong, can satisfy the instructions for use of particular surroundings.

2, the utility model adopts armature to drive the form of push rod, realizes the contact conversion of contact system, has guaranteed product electric insulation and withstand voltage properties, has improved the contact reliability of product.

3, the utility model is particularly suitable for the usefulness of changing-over circuit in space flight, aviation and ground-based electronic equipment and other automatic control equipment.

Embodiment:

1,2 a kind of embodiment of the present utility model is described by reference to the accompanying drawings.

A kind of 1/2 Crystal Can Relay electromagnetic system, by cover plate 1, support 2, armature 3, coil 4, unshakable in one's determination 5, magnet steel 6, vertical shaft 8, yoke I 9, yoke II 10, yoke III 11 forms, described yoke I 9, yoke II 10, yoke III 11 is fixed between support 2 and the cover plate 1, and yoke I 9, be fixed with unshakable in one's determination 5 between the yoke II 10, be set with coil 4 on unshakable in one's determination 5, yoke II 10, be fixed with magnet steel 6 between the yoke III 11, armature 3 is installed between support 2 and the cover plate 1 by vertical shaft 8 and is positioned at the place ahead of coil 4, and yoke III 11 front ends have inside flexure plane 14, and armature 3 right-hand members are curved inwardly between the face 14 at yoke II 10 front end faces and yoke III 11 front ends.

The right-hand member of described armature 3 outside is shaped with inclined-plane 15, and when static in inclined-plane 15 and yoke III 11 front ends flexure plane 14 fit, improve the reliability of adhesive.The outside of described yoke I 9 is fixed with damping reed 7, and the cantilever end of damping reed 7 is fitted in the left end of armature 3, during release condition, applies certain pressure at the left end of armature 3, the sensitivity the during conversion of raising state and the reliability that magnetic keeps when static.The two ends, the left and right sides of described armature 3 are fixed with push rod I 12, push rod II 13.

Operation principle: when electromagnetic system was static, because the effect of magnet steel 6 magnetic force, armature right-hand member 3 kept attracting states with the interior flexure plane 14 of yoke III 11 front ends; After coil 4 is pressed the polar requirement excitation, because the flow direction that coil 4 produces is opposite with the flow direction of magnet steel 6, under the effect of electromagnetic attraction, overcome the magneticaction of magnet steel 6, armature 3 is rotated counterclockwise break away from flexure plane 14 and the 10 maintenance adhesives of yoke II in yoke III 11 front ends, thereby rotate with the fixing push rod I 12 in two ends, moving armature 3 left and right sides, push rod II 13, and then realize the contact conversion by contact system.After coil 4 de-energisations, because the disappearance of electromagnetic attraction, be subjected to the magneticaction of magnet steel 6, armature 3 clockwise rotate return with yoke III 11 front ends in flexure plane 14 keep adhesives, electromagnetic system turns back to again static state.

Above-described embodiment is preferred embodiment of the present utility model, is not to limit the utility model practical range, therefore all equivalent variations of being done with the described content of the utility model claim all should be included within the utility model claim scope.
