Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

In the description of the present utility model, unless otherwise indicated, the meaning of "plurality" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front," "rear," "head," "tail," and the like are used as an orientation or positional relationship based on that shown in the drawings, merely to facilitate description of the utility model and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the utility model.

Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Embodiment one:

an electromagnetic relay, including base 1, pressure spring 2, magnetic circuit subassembly 3, armature 4, push rod 5 and contact system 6, base 1 is equipped with the cavity 13 that holds magnetic circuit subassembly 3, cavity 13 bottom is equipped with yoke locating hole 11, the tip of cavity 13 is equipped with yoke convex closure guide angle 12, magnetic circuit subassembly 3 includes yoke 31, yoke 31 bottom is equipped with convex closure 311, magnetic circuit subassembly 3 can be put into cavity 13 from the tip of base 1, in the in-process of base 1 is put into to magnetic circuit subassembly 3, convex closure 311 moves along convex closure guide angle 12, thereby prevent scraping the burr when magnetic circuit subassembly 3 installation. The convex hull 311 is matched with the yoke positioning hole 11, and after the magnetic circuit assembly 3 enters the cavity 13, the convex hull 311 falls into the yoke positioning hole 11, so that the magnetic circuit assembly 3 and the base 1 are positioned.

The lateral part of the magnetic circuit assembly 3 is provided with a connecting column 32 and a connecting groove 1, the bottom 41 of the armature 4 is arranged in the connecting groove 33, the armature 4 is integrally positioned on the inner side of the connecting column 32, the armature 4 can rotate along the connecting groove 33, and when the magnetic circuit assembly 3 is electrified, the magnetic circuit assembly 3 adsorbs the armature 4. The one end of base 1 that keeps away from the armature is equipped with contact system 6, and contact system 6 includes movable contact 61 and stationary contact 62, and push rod 5 sets up on base 1 and can follow cell body 15 motion, and push rod 5 is located the top of magnetic circuit assembly 3 to restrict the up-and-down motion of magnetic circuit assembly 3. One end of the push rod 5 is connected with the movable contact 61, the other end of the push rod 5 is connected with the armature 4, and when the magnetic circuit assembly 3 adsorbs the armature 4, the armature 4 drives the push rod 5 to move, so that the movable contact 61 moves towards the fixed contact 62 and contacts with the fixed contact, and electric conduction is realized.

The bottom of the yoke 31 is provided with two sinking tables 312, and the compression spring 2 is provided with buckles 21 corresponding to the sinking tables 312. The pressure spring 2 is provided with a avoidance groove 22, and when the buckle 21 is arranged in the sinking table 312, the convex hull 311 is positioned in the avoidance groove 22. The outer side of the armature 4 is provided with a protrusion 42, and the compression spring 2 is provided with a through hole 23 corresponding to the protrusion 42. When the buckle 21 of the pressure spring 2 is arranged on the sinking platform 312 and the through hole 23 is sleeved on the convex part 42, the pressure spring 2 applies a deformation force far away from the magnetic circuit assembly 3 to the armature 4. Therefore, when the magnetic circuit assembly 3 is powered off, the pressure spring 2 enables the armature 4 to be separated from the magnetic circuit assembly 3, and the armature 4 drives the push rod 5 to move, so that the movable contact 61 is separated from the stationary contact 62.

When the relay is installed, firstly, the armature 4 is installed on the inner side of the connecting column 32, then the buckle 21 of the pressure spring 2 is arranged in the sinking table 312 of the yoke 31, and the through hole 23 is sleeved on the convex part 42 of the pressure spring 2; then, the movable contact 61 and the armature 4 are sleeved on the push rod 5 by placing the movable contact into the cavity 13 along the end of the base 1, and inserting the convex hull 311 into the yoke positioning hole 11. Because the positioning of the magnetic circuit assembly 3 is realized through the structure, the pressure spring is effectively connected with the armature through the matching of the buckle and the sinking table. Therefore, dispensing is not needed when the relay is assembled, the colloid solidification time is reduced, the assembly time is shortened, and the production efficiency is improved.
