Description
Technical Field
[0001] The utility model relates to the technical field of relays, and more specifically, the utility model relates to a relay with a limit support frame. Background Art
[0002] In recent years, with the rapid development of the electronic information industry, relays, as basic components, have been widely used in automation control fields such as household appliances, communications, automobiles, instrumentation, machinery and equipment, aerospace, etc. The latest statistical data shows that among electronic component products, relays have become the largest product in terms of annual sales. The magnetic latching relay is a new type of relay developed in recent years. As one of the important components for intelligent control, it plays an important role. Like other electromagnetic relays, it plays the role of automatically connecting and disconnecting the circuit. The difference is that the normally closed or normally open state of the magnetic latching relay completely depends on the action of the permanent magnet. The conversion of its switch state is triggered by a pulse electrical signal with a certain width and is completed. It has the characteristics of power saving, stable performance, small size, large load capacity, and superior performance compared with other relays. Therefore, the magnetic latching relay is more and more widely used.
[0003] An existing magnetic latching relay, with the publication number CN 108878220 B, includes a relay base and a relay upper cover. An installation partition is arranged in the middle of the relay base. An electromagnetic system is arranged on one side of the installation partition, and a contact system is arranged on the other side. The electromagnetic system is connected to the contact system through a pushing card; the electromagnetic system includes an electromagnet assembly and a moving armature assembly, and the electromagnet assembly is glued to the relay base; the contact system includes a static contact assembly and a moving contact assembly. The static contact assembly is fixedly connected to the relay base. One end of the moving contact assembly is arranged in the middle of the static contact assembly, and the other end is fixedly connected to the relay base; one end of the pushing card is drivingly connected to the moving armature assembly, and the other end is clamped to the moving contact assembly. In this kind of magnetic latching relay, due to magnetic chips being easily adsorbed to the armature, the sensitivity of the relay is affected, and the fixing effect is not good, which is prone to failure and affects the use.

Specific embodiments
[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0019] Refer to Figures 1 - 3 , in the embodiment of the present utility model, a relay with a limit support frame includes a base 1, a coil 2, a support frame 3, a magnet steel assembly 4, and a push piece 5. The coil 2 is installed on the right side of the base 1, and both ends of the left side of the coil 2 are connected to the magnet steel assembly 4. The magnet steel assembly 4 is provided with a support frame 3 outside, and the support frame 3 is clamped on the base 1 through the clamping groove 36. The lower side of the magnet steel assembly 4 is clamped to the right side of the push piece 5.
[0020] The support frame 3 includes a support frame body 31, a rotating shaft hole 32, a connecting block one 33, a connecting block two 34, a connecting block three 35, and a clamping groove 36. The connecting block one 33 and the connecting block two 34 are provided on the left side of the support frame body 31, the connecting block three 35 is provided on the upper side of the support frame body 31, and the rotating shaft hole 32 is arranged at the lower right corner of the support frame body 31. The connecting block one 33, the connecting block two 34, and the connecting block three 35 are clamped and fixed on the base 1 through the bottom limit groove 36, and the magnet steel assembly 4 is rotatably connected to the rotating shaft hole 32.
[0021] It further includes a moving spring lead piece 6, a static spring lead piece 7, a conductive piece 8, a right main contact 9, a left main contact 10, a right auxiliary contact 11, and a left auxiliary contact 12. The lower side of the conductive piece 8 is clamped on the left side of the pushing piece 5. The conductive piece 8 is arranged in three layers in a "Ji" shape. The lower right side of the conductive piece 8 is fixed with a moving spring elastic piece 13. The lower ends of the conductive piece 8 and the moving spring elastic piece 13 are both clamped on the left side of the pushing piece 5. The upper side of the conductive piece 8 is fixed on the upper side of the moving spring lead piece 6. The right main contact 9 and the right auxiliary contact 11 are arranged on the conductive piece 8. Corresponding to the left side of the right main contact 9 and the right auxiliary contact 11, there are a left main contact 10 and a left auxiliary contact 12. The left ends of the left main contact 10 and the left auxiliary contact 12 are fixedly connected to one end of the static spring lead piece 7. The moving spring lead piece 6 and the static spring lead piece 7 extend out of the base 1.
[0022] For a relay with a limit support frame of the present utility model, when it is turned on and used, the coil 2 is energized, and the magnet assembly 4 on the support frame 3 rotates around the axis. There are clamping grooves 36 at the bottoms of several connecting blocks on the support frame 3. The main body 31 of the support frame is clamped on the base 1 through the clamping grooves 36, thereby improving the overall stability of the relay. The two armature iron pieces contact the two connecting ends on both sides and rotate to control the movement of the pushing piece 5 by the push rod. When the pushing piece 5 moves to the right, it drives the conductive piece 8 in the limiting groove 51 to move to the right, causing the contacts to disconnect. Since there is a step on the side of the limiting groove 51 close to the auxiliary contact, the right auxiliary contact 11 disconnects from the left auxiliary contact 12 first, and then the right main contact 9 disconnects from the left main contact 10. The arranged step can make the disconnection occur successively, avoiding arc impact and improving the safety of the circuit. When the pushing piece 5 moves to the left, the right main contact 9 and the left main contact 10 close first, and then the right auxiliary contact 11 and the left auxiliary contact 12 close.
[0023] The above embodiments are illustrative of the present utility model, not limiting of the present utility model. Any scheme obtained by simply transforming the present utility model belongs to the protection scope of the present utility model.
