The moving iron core support 22 compresses the elastic element 4, and the moving contact and the stationary contact are either in contact or disconnected. When the coil is de-energized, the elastic element 4 drives the moving contact support 12 and the contact support 12 to slide away from the stationary contact, and the moving iron core 23 and the stationary iron core separate, and the moving contact and the stationary contact are either disconnected or in contact.

[0050] In another embodiment, at least one elastic element 4 is provided between the moving iron core support 22 and the control module housing 21. The elastic element 4 is a compression spring.

[0053] The first boss 223 can be installed in the first groove 123 for installation and fixation. By locking the first boss 223 and the first groove 123 together, the linkage between the contact support 12 in the contact module 1 and the moving iron core support 22 in the control module 2 is realized. The installation is convenient, the structure is simple, and it is convenient to install, disassemble and replace the contact module 1, saving costs and improving installation efficiency.

[0057] Furthermore, such as Figure 2 , Figure 3 , Figure 6 and Figure 7As shown, two first locking members 33 are installed at both ends of the first connecting shaft 3. After the first connecting shaft 3 is installed in the first through hole 31 and the second through hole 32, both ends extend out of the first through hole 31 of the first groove 123 to form first locking parts 34 on the groove wall of the first groove 123. The two first locking members 33 are respectively installed on the two first locking parts 34. The two first locking members 33 can clamp the first boss 223 and the first groove 123 in the second direction D2, and at the same time limit the axial movement of the first connecting shaft 3 to prevent the first connecting shaft 3 from falling out of the first through hole 31 and the second through hole 32. Figure 3 The diagram shows the structure of the contact support 12 and the moving iron core support 22 after installation in an embodiment of this application.

The second through hole 32 penetrates the arc-shaped platform 224 and the rectangular platform 225.

[0060] Preferably, the contact module housing 11 is provided with a first mounting hole, and the contact support 12 is embedded in the first mounting hole; the control module housing 21 is provided with a second mounting hole, and the moving iron core support 22 is embedded in the second mounting hole.

[0061] Preferred, such as Figure 4As shown, the contact support 12 includes at least one moving contact mounting portion 121, which is integrally formed with the first linkage portion 122.

The guide rib 226 is located in the plane containing the first direction D1 and the third direction D3, and the second linkage part 221 is located in the plane containing the second direction D2 and the third direction D3. The guide rib 226 is perpendicular to the second linkage part 221 and integrally formed. In this embodiment, the integral forming of the second linkage part 221 and the guide rib 226 reduces the number of parts, facilitates installation and management, and improves installation efficiency.

[0063] Furthermore, guide ribs 226 are connected to both sides of the second linkage part 221. The extending direction of the two guide ribs 226 is opposite to the protruding direction of the first boss 223.

When the control module housing 21 and the moving iron core support 22 are installed, the limiting rib 24 presses against the limiting plate 25. The limiting plate 25 is elastic and can undergo plastic deformation to avoid the limiting rib 24, making installation and disassembly more flexible. After the limiting rib 24 is installed in the limiting hole or limiting groove, the limiting plate 25 is reset, thereby locking the limiting rib. 24 is locked on the limiting plate 25, wherein the limiting hole or limiting groove has a movable space, the limiting rib 24 extends into the limiting hole or limiting groove for sliding engagement, the elastic member 4 is connected to the moving iron core support member 22, and the elastic member 4 is configured to drive the moving iron core support member 22 to move away from the stationary iron core, so that the moving iron core support member 22 can approach the control module housing 21 when the coil is energized, and when the coil is de-energized, the elastic member 4 drives the moving iron core support member 22 away from the control module housing 21, so that the limiting rib 24 abuts against the side wall of the limiting hole or limiting groove. In this way, the moving iron core support member 22 can be fixedly installed on the control module housing 21 by the elastic member 4.

[0068] Furthermore, such as Figures 9-11 As shown, the ends of the limiting rib 24 and the limiting plate 25 are provided with chamfers 26, and the two chamfers 26 are opposite each other in the assembly direction.

The third locking part includes the limiting plate 25, and the side of the limiting plate 25 facing the moving iron core support 22 protrudes to form a hook. The second locking part is a second slot opened on the side of the moving iron core support 22. The hook and the second slot correspond to each other. When the control module housing 21 and the moving iron core support 22 are installed, the side of the moving iron core support 22 abuts against the hook, causing the limiting plate 25 to plastically deform. After the hook extends into the second slot, the limiting plate 25 is reset. The second slot has a sliding space, and the hook can slide in the second slot, thereby realizing the snap-fit ​​sliding installation of the second locking part and the third locking part.

[0073] Preferred, such as Figures 9-11 As shown, the moving iron core 23 and the moving iron core support 22 are fixedly installed by at least one second connecting shaft 27.
