The components in the figures are not drawn to scale and like reference numerals are generally used to designate like components.

The utility model will now be further described with reference to the drawings and detailed description.

Referring to fig. 1 to 12, the present embodiment provides an impact-resistant magnetically latching electromagnetic relay, which includes a base 10, and an electromagnetic portion 20, a push block 40 and a contact portion 30 mounted on the base 10; the electromagnetic part 20 comprises a coil assembly 21, an iron core 22, magnetic steel 24, an armature 25 which is hinged to form a teeterboard structure, and two yokes 23 which are respectively assembled at two ends of the iron core 22, specifically, the iron core 22 is penetrated in the coil assembly 21, and the two yokes 23 are assembled at the left end and the right end of the iron core 22; the magnetic steel 24 corresponds to the middle position of the iron core 22 and contacts with the iron core, and the armature 25 is hinged above the magnetic steel 24. The iron core 22, the magnetic steel 24 and the two yokes 23 form an E-shaped magnetic conductive structure turned 90 degrees sideways, as shown in fig. 8.

Specifically, two yokes 23 are assembled at both left and right ends of the iron core 22; the yoke 23 at the left end is defined as a left yoke 1, and the yoke 23 at the right end is defined as a right yoke 2. The left end and the right end of the armature 25 correspond to the left yoke 23 and the right yoke 23 respectively, namely the left end of the armature 25 corresponds to the left yoke 1, and the right end of the armature 25 corresponds to the right yoke 2. The contact part 30 comprises a static spring part 32 and a dynamic spring part 31, specifically, the static spring part 32 comprises a static spring 321 and a static contact 322 arranged on the static spring 321, and the dynamic spring part 31 comprises a dynamic spring 311 and a dynamic contact 312 arranged on the dynamic spring 311; the stationary contact 322 of the stationary spring portion 32 and the movable contact 312 of the movable spring portion 31 are disposed in correspondence.

The right end of the armature 25 is connected with the moving spring part 31 (specifically, the moving spring 311) of the contact part 30 through a pushing block 40, so that the left-right swing of the armature 25 can drive the moving spring part 31 to act through the pushing block 40, and further separation or closure with the static spring part 32 is realized. In this embodiment, the armature 25 swings leftwards, and the moving spring portion 31 is driven to move away from the fixed spring portion 32, and the armature 25 swings rightwards, and the moving spring portion 31 is driven to move close to the fixed spring portion 32. The armature 25 is configured to: when the armature 25 swings rightward to drive the movable spring portion 31 to just contact the stationary spring portion 32 (i.e., at the instant when the movable contact 312 of the movable spring portion 31 and the stationary contact 322 of the stationary spring portion 32 contact), a spacing L1 between the left end of the armature 25 and the yoke 23 (i.e., the left yoke 1) at the left end is smaller than a spacing L2 between the right end of the armature 25 and the yoke 23 (i.e., the right yoke 2) at the right end, as particularly shown in fig. 1.

So set up, this relay is in the intermediate state because of receiving external force impact and leading to armature 25 to swing right in order to drive moving spring part 31 to contact with quiet spring part 32, because interval L1 between yoke 23 of the left end and the left end of armature 25 is less than interval L2 between yoke 23 of the right end and the right end of armature 25, armature 25 left side suction (i.e. restoring force) > armature 25 right side suction (i.e. actuating force) this moment, again because contact this moment, the contact clearance reduces to 0, moving spring 311 of moving spring part 31 takes place the deformation, the reed counter force F >0 that produces, the counter force effect is unanimous with relay restoring force, all order to drive armature 25 to swing left. Thus, the reaction force of the moving spring 311, the left side attractive force of the armature 25 and the right side attractive force of the armature 25 are more than 0. The armature 25 can be timely swung leftwards to reset, so that the moving and static contacts are driven to be separated; the gap between the movable contact and the static contact is ensured, so that the situations of contact bonding, breakdown and even explosion caused by load short circuit when the contact contacts or the micro gap exist in the intermediate state are avoided when the load of the client is connected.

Of course, in other embodiments, the left and right yokes 23 may be set to different heights, such as the left yoke 1 being higher than the right yoke 2, so long as the distance L1 between the left end of the armature 25 and the left yoke 1 is smaller than the distance L2 between the right end of the armature 25 and the right yoke 2 when the armature 23 swings rightward to drive the moving spring portion 31 just in contact with the stationary spring portion 32.

That is, in the process of swinging the armature 25 rightward, firstly, the armature 25 abuts against the lower side wall of the upper notch 41 and presses the pushing block 40 downwards, the lower movement of the pushing block 40 makes the upper side wall of the lower notch 42 abut against the moving spring 311 of the contact portion 30 and drives the moving spring 311 to move downwards together, so that the moving spring 311 deforms until the moving contact point contacts with the moving contact point.

When the relay is in an operating state, the armature 25 swings left and right under the action of the magnetic conductive structure, and when the armature 25 swings left, the armature is abutted against the transverse portion 232 of the yoke 23 at the left end through the abutting inclined surface 251 at the left end, and at this time, the moving and static contacts of the contact portion are disconnected, as shown in fig. 7 and 8. When the armature 25 swings rightward, the contact portion 30 is closed with the moving contact point in contact with the lateral portion 232 of the yoke 23 attached to the right end by the contact slope 251 of the right end. The lateral portion 232 of the yoke 23 and the contact inclined surface 251 of the armature 25 are provided, and when the contact inclined surface 251 contacts the lateral portion 232, the contact inclined surface 251 and the surface of the lateral portion 232 can be well flatly attached together; the contact area between the armature 25 and the yoke 23 is increased, the attraction force of the armature 25 in the action process can be improved, and the action time of the relay is shortened, so that the contact reliability of the contact is improved, and the requirements of high load and long service life are met.
