[0002] In power supply systems, AC contactors are mainly used for remotely connecting and disconnecting current circuits. They are widely used due to their simple control and economic practicality. A contactor is an electromagnetic switching device used for long-distance, frequent switching of large currents (main circuits), and is widely used in motor control, power distribution, industrial automation, and other fields. It uses electromagnetic force to drive the contacts to connect or disconnect the circuit, and is suitable for both AC and DC systems.

[0003] A mechanical self-locking contactor is an electrical control device that combines the on / off function of a contactor with a mechanical self-locking mechanism.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] In one embodiment, such as Figure 1 - Figure 4 As shown, a mechanical self-locking contactor device includes a base plate 1, a contactor body 11 is installed in the middle of the top of the base plate 1, and a sliding groove 12 is installed on one side of the contactor body 11.

[0030] The sliding groove 12 is slidably connected to a connecting component, which includes an insertion plate 2. The insertion plate 2 is slidably connected to the inside of the sliding groove 12. A relay 21 is installed on the top of the insertion plate 2. A through hole 22 is opened on one side of the inside of the relay 21. The through hole 22 vertically penetrates the relay 21 and the insertion plate 2.

[0031] The through hole 22 is internally connected to a limit assembly;

[0032] Two switch assemblies are provided on the top two sides of the base plate 1.

[0033] In this embodiment, the bottom of the contactor body 11 is supported by the base plate 1, the connecting components are connected by the sliding groove 12, the relay 21 is connected by the insertion plate 2 inserted into the sliding groove 12, the limiting component is installed by the through hole 22, and the connection between the insertion plate 2 and the sliding groove 12 is fixed by the limiting component. There are two switch components: one switch controller 3 is a normally closed switch, and the other is a normally open switch.

[0034] In one embodiment, such as Figure 1 and Figure 2 As shown, a limiting block 13 is installed at the bottom of the sliding groove 12, and a strong magnetic plate 14 is installed inside the limiting block 13. The strong magnetic plate 14 attracts the iron plate 24, thereby preventing the insertion plate 2 from detaching from the sliding groove 12.

[0035] In one embodiment, such as Figure 1 and Figure 2 As shown, two support blocks 15 are installed on the top two sides of the base plate 1. An insertion slot 16 is provided on one side of the support block 15. The switch assembly and the support block 15 are connected by inserting the fixing component into the insertion slot 16.

[0036] In one embodiment, such as Figure 1 and Figure 2 As shown, two connecting plates 17 are installed on both sides of the base plate 1, and two connecting bolts 18 are provided on both sides of the interior of the connecting plate 17. The base plate 1 is installed by means of the connecting bolts 18.

[0037] In one embodiment, such as Figure 1 and Figure 3 As shown, the limiting component includes a sliding rod 23, which is slidably connected inside the through hole 22. An iron plate 24 is installed at the bottom of the sliding rod 23, and a limiting plate 25 is installed at the top of the sliding rod 23. A pull ring 26 is installed at the top of the limiting plate 25. By pulling the pull ring 26, the sliding rod 23 is driven to slide upward inside the through hole 22, thereby causing the iron plate 24 to disengage from the strong magnetic plate 14.

[0038] In one embodiment, such as Figure 1 , Figure 3 and Figure 4 As shown, the switch assembly includes a switch controller 3. A fixing groove 33 is provided on the top of the switch controller 3. The fixing groove 33 is fitted and connected to the support block 15. Two wiring grooves 31 are provided on one side of the switch controller 3. A button 32 is provided on the bottom of the switch controller 3. A movable groove 34 is provided on one side inside the fixing groove 33. The switch controller 3 is connected and installed by fitting the fixing groove 33 and the support block 15.

[0039] In one embodiment, such as Figure 1 and Figure 4 As shown, a fixing component is slidably connected inside the moving slot 34, which limits the movement between the switch controller 3 and the support block 15.

[0040] In one embodiment, such as Figure 1 and Figure 4As shown, the fixing component includes a fixing plate 35, which is slidably connected inside the moving groove 34. A buckle 36 is installed on one side of the fixing plate 35, and the fixing plate 35 can be slid inside the moving groove 34 by pulling the buckle 36.

[0041] The above embodiment discloses a mechanical self-locking contactor device, wherein the base plate 1 is fixed in a suitable position by connecting bolts 18 on both sides inside the connecting plate 17, and the contactor body 11 is installed on the base plate 1. The insertion plate 2 on one side of the relay 21 is inserted into the sliding groove 12, and the relay 21 is connected by the sliding connection between the insertion plate 2 and the sliding groove 12. The relay 21 is installed by the attraction of the iron plate 24 and the strong magnetic plate 14 inside the limiting block 13. The top of the through hole 22 is limited by the limiting plate 25, thereby preventing the insertion plate 2 from disengaging from the sliding groove 12 during use. When disassembling relay 21, pulling the pull ring 26 causes the sliding rod 23 to slide upward inside the through hole 22, thereby causing the iron plate 24 to detach from the strong magnetic plate 14, facilitating the disassembly of relay 21. The switch controller 3 is connected by the engagement of the fixing groove 33 and the support block 15. By pushing the pull buckle 36, the fixing plate 35 slides inside the moving groove 34, causing the fixing plate 35 to insert into the insertion groove 16 on one side of the support block 15, thereby limiting the connection between the support block 15 and the switch controller 3, improving the convenience of the device, and facilitating the disassembly and maintenance of the self-locking structure.

[0042] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
