[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-9As shown, this utility model provides a technical solution: a high-power magnetic latching relay, including a housing 1, an insulating base 2 fixedly connected to the center inside the housing 1, a coil frame 3 fixedly connected to one side inside the insulating base 2, multiple yokes 301 fixedly connected to one side of the outer wall of the coil frame 3, and multiple copper-clad steel needles 302 fixedly connected to one side of the inner wall of the coil frame 3. Circular holes 201 are opened on both sides of the inner wall of the insulating base 2, and a rotating base 4 is rotatably connected to the center inside the insulating base 2. Multiple armatures 401 are fixedly connected to both sides inside the rotating base 4, and rotating ball heads 402 are provided on both sides of the outer wall of the rotating base 4. A push card 5 is slidably connected to the top inside the insulating base 2, and sliding grooves 202 are opened on both sides of the outer wall of the insulating base 2. Multiple sliding ball heads 403 are provided on the top of the outer wall of the rotating base 4. An movable groove 501 is opened in the center inside the push card 5, and multiple limiting posts 502 are provided on both sides of the outer wall of the push card 5.

[0028] A movable spring terminal 6 is fixedly connected to one side of the interior of the insulating base 2. A first movable spring 601 and a second movable spring 602 are fixedly connected to the top of one side of the movable spring terminal 6. Movable contacts 603 are riveted to the top of the outer walls of the first movable spring 601 and the second movable spring 602. A stationary spring terminal 7 is fixedly connected to one side of the interior of the insulating base 2. A stationary spring 701 is fixedly connected to the top of the outer wall of the stationary spring terminal 7. A stationary contact 702 is riveted to the top of one side of the stationary spring 701.

[0029] Through the interlocking structure between the first moving spring 601 and the second moving spring 602, the heat dissipation capacity inside the device is improved to a certain extent while increasing the current carrying capacity. By setting rotating ball heads 402 on both sides of the outer wall of the rotating base 4, the moving contact 603 and the stationary contact 702, as well as the yoke 301 and the armature 401, can achieve precise and reliable rotational contact operation by simply sliding the push card 5, so as to achieve the effect of maintaining the continuity of the magnetic circuit. The inclined surface is opened on the outer wall of the armature 401 to ensure the tight fit between the armature 401 and the yoke 301, reduce magnetic leakage, and make fuller use of the magnetic circuit. Therefore, under the action of the yoke 301 and the armature 401, the circuit can be continuously connected or disconnected without continuously consuming electrical energy.

[0030] like Figure 3-8 As shown, the outer wall of one end of the rotating ball head 402 is connected through the center of the round hole 201, and the outer wall of the rotating ball head 402 is rotatably connected to the inner wall of the round hole 201. The movable groove 501 is roughly rectangular. Under the combined action of the rotating ball head 402 and the round hole 201, the rotating base 4 can drive the armature 401 to rotate smoothly inside the insulating base 2.

[0031] The outer wall of one end of the sliding ball head 403 is connected through to the inside of the movable groove 501, and the outer wall of the sliding ball head 403 is slidably connected to the inner wall of the movable groove 501. When the push card 5 moves, it can drive the sliding ball head 403 and the rotating base 4 to rotate through the movable groove 501. When the sliding ball head 403 slides up and down inside the movable groove 501, it will also be accompanied by a certain degree of rotation.

[0032] like Figure 6 As shown, one side of the outer wall of the armature 401 is tightly fitted to one side of the outer wall of the yoke 301, and a slope is provided on the corresponding side of the armature 401. The slope provided on the outer wall of the armature 401 makes the armature 401 and the yoke 301 fit more tightly.

[0033] like Figure 3-5 As shown, the sliding groove 202 is roughly rectangular in shape, and both sides of the inner wall of the sliding groove 202 are provided with arc-shaped surfaces. One end of the outer wall of the limiting post 502 is connected to one end of the inner wall of the sliding groove 202, and the outer wall of the limiting post 502 is slidably connected to one end of the inner wall of the sliding groove 202. Under the action of the sliding groove 202 and the limiting post 502, the push card 5 can slide smoothly along the inner wall of the sliding groove 202.

[0034] like Figure 3 , Figure 4 , Figure 6 and Figure 9 As shown, the top of the outer wall of the first moving spring 601 is bent 90° toward the coil frame 3. The head of the first moving spring 601 is bent 90° to support the push card 5, and together with the second moving spring 602, it limits the push card 5.

[0035] The top of the outer wall of the second moving spring 602 is bent 90° toward the stationary spring 701. The 90° bend of the head of the second moving spring 602 achieves the anti-dislodgement effect of pushing the card 5.

[0036] Working principle: Under the combined action of the rotating ball head 402 and the round hole 201, the rotating base 4 can drive the armature 401 to rotate smoothly inside the insulating base 2. The sliding ball head 403 and the rotating base 4 can be driven to rotate through the movable groove 501. When the sliding ball head 403 slides up and down inside the movable groove 501, it will also rotate to a certain extent. Through the inclined surface opened on the outer wall of the armature 401, the armature 401 and the yoke 301 are more closely fitted. Under the action of the sliding groove 202 and the limiting post 502, the push card 5 can slide smoothly along the inner wall of the sliding groove 202. The head of the first moving spring 601 is bent at 90°, which can support the push card 5 and together with the second moving spring 602, limit the push card 5. The head of the second moving spring 602 is bent at 90° to achieve the anti-disengagement effect of the push card 5.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
