Description

Technical Field

[0001] This invention relates to the field of contactor technology, and more specifically to a contactor driving device. Background Technology

[0002] A contactor is an electrical component that uses electromagnetic principles to control the opening and closing of a circuit. It consists of an electromagnetic system (coil and iron core) and a contact system. A small current control signal drives the electromagnetic system to close or open the contacts, achieving indirect control of a high-current main circuit. It is widely used in power, industrial automation, and other fields, capable of frequent circuit operation and providing both control and protection functions.

[0003] For example, patent application CN202511311185.2 discloses a multi-functional contactor, including an upper housing and a base that snaps into the upper housing. Inside the upper housing and base, from top to bottom, are arranged a movable bracket, a moving iron core, a coil bracket, a coil winding, and a stationary iron core. The coil bracket, coil winding, and stationary iron core are fixed inside the base. The coil bracket is sleeved on the stationary iron core. A return spring is provided between the coil bracket and the moving iron core. The movable bracket is connected to the moving iron core and slides within the upper housing. Multiple sets of movable contact groups are arranged parallel to each other on the movable bracket, and fixed contact groups are provided on both sides of each set of movable contact groups. In this type of contactor, the electromagnetic structure is relatively large. When the moving iron core and the stationary iron core are attracted, they need to overcome not only the weight of the moving iron core itself but also the elastic force of the return spring, resulting in high power consumption and high coil temperature rise. Furthermore, the manual operation structure of existing contactors is usually quite complex, not only increasing the overall size of the contactor but also making the assembly process cumbersome.

[0015] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0016] Refer to the above appendix Figure 1-4 As shown, the contactor driving device provided by the present invention includes a detachably connected left housing 1 and a right housing 2. The left housing 1 has multiple first wiring frames 3, each connected to multiple stationary contacts 4. The right housing 2 has multiple second wiring frames, each connected to a moving contact 5 aligned with a stationary contact 4. The device is characterized in that: a push plate 10, capable of driving the moving contact 5 to contact or disengage from the stationary contact 4, is movably disposed within the right housing 2; a handle 25 linked to the push plate 10 is disposed within the right housing 2; a swing element 14 linked to the push plate 10 is also disposed within the right housing 2; a conductive plate 6 is connected to each of the second wiring frames; a moving spring assembly 7 is disposed on the conductive plate 6; the moving contact 5 is disposed on the moving spring assembly 7; a first sliding groove 8 and a frame 9 are disposed within the right housing 2; the push plate 10 is slidably disposed within the first sliding groove 8; the push plate... The 10 has an opening 11 for inserting the capacitive spring assembly 7. The frame 9 has an iron core 12 and a coil 13 is wound around the frame 9. The swing member 14 has a permanent magnet. The permanent magnet has armature plates 15 extending through the front and rear ends of the swing member 14 on its upper and lower sides. The iron core 12 is connected to yoke plates 16 between the two armature plates 15 inserted at the front and rear ends of the swing member 14. The push plate 10 also has a first slot 17. The lower end of the swing member 14 has a linkage part 18 inserted into the first slot 17. The right housing 2 has a support 19 and a clamping plate 20. The support 19 has a first round hole 21. The clamping plate 20 has a second round hole aligned with the first round hole 21. The left end of the swing member 14 has a first post inserted into the first round hole 21, and the right end has a second post 23 inserted into the second round hole.

[0017] In this embodiment, the magnetic poles of the two yoke iron plates 16 can be changed by controlling the energizing direction of the coil 13. Different magnetic poles of the two yoke iron plates 16 can attract different armature plates 15, causing the swing member 14 to swing back and forth. The swing member 14 can drive the push plate 10 to slide back and forth through the linkage part 18, thereby driving the moving spring assembly 7 to swing back and forth, so that the moving contact 5 contacts or disengages from the stationary contact 4, realizing opening and closing control. By controlling the energizing and de-energizing of the coil 13, the magnetic force of the two yoke iron plates 16 can be controlled. When the coil 13 is de-energized and the magnetic force of the two yoke iron plates 16 disappears, the magnetic force of the permanent magnet itself is used to maintain the attraction and holding state with the armature plate 15. This structure replaces the existing moving iron core 12 and stationary iron core 12 structure, resulting in lower power consumption, lower coil 13 temperature rise, and smaller size. The swing member 14 is positioned and oscillated by the cooperation of the first column and the first round hole 21 of the support 19, the second column 23, and the second round hole of the clamping plate 20, making the swing member 14 move more stably and accurately.

[0018] Reference Figure 1-4As shown, this is a first embodiment of the linkage structure of the handle 25. The clamping plate 20 at the left end of the second round hole is provided with a sleeve 24 protruding to the left. The handle 25 is sleeved on the sleeve 24, and the lower end of the handle 25 is inserted into the first slot 17. The upper part of the right housing 2 is provided with a second sliding groove 26. The second sliding groove 26 has a first through hole 27 running through it vertically. The second sliding groove 26 is slidably provided with a paddle 28. The upper end of the paddle 28 is provided with a button 29 that extends out of the upper end of the right housing 2, and the lower end is provided with a second slot 30 for the upper end of the handle 25 to be inserted. The paddle 28 on both sides of the button 29 is provided with an indicator mark. The indicator mark can be exposed through the first through hole 27 or hidden in the second sliding groove 26 as the paddle 28 moves.

[0019] In this embodiment, by tossing the toggle switch 29, the lever 28 can slide back and forth in the second slide groove 26. The lever 28 can cause the handle 25 to swing back and forth. The handle 25 can cause the push plate 10 to slide back. The push plate 10 causes the moving spring assembly 7 to swing back and forth, so that the moving contact 5 contacts or disengages from the stationary contact 4, thereby realizing opening and closing control. The indicator mark moves with the lever 28 and can be exposed through the first through hole 27 or hidden in the second slide groove 26 to indicate the status of the contactor. During assembly, the push plate 10 is placed in the first slide groove 8 and the moving spring assembly 7 is inserted into the opening 11. Then, the handle 25 is sleeved in the sleeve 24, so that the upper end of the handle 25 is inserted into the second slot 30 and the lower end is inserted into the first slot 17. The assembly is simple and convenient.

[0020] Reference Figure 5 As shown, this is a second embodiment of the linkage structure of the handle 25. The clamping plate 20 is provided with a sleeve 24, and the handle 25 is fitted onto the sleeve 24, with its lower end inserted into the first slot 17. The upper part of the right housing 2 is provided with a third sliding groove 31, and the lower end of the third sliding groove 31 is provided with a second through hole 32 for the handle 25 to pass through and swing. The manual operating mechanism includes a lever 33 slidably disposed within the third sliding groove 31. The lower end of the lever 33 is provided with a third slot 34 for the upper end of the handle 25 to be inserted into. Buttons that can pass through the upper end of the right housing 2 are provided in the third sliding grooves 31 on both the front and rear sides of the lever 33. 35. Both ends of the toggle block 33 have a first L-shaped plate 36. The inner side of the upper end of the first L-shaped plate 36 has a transition arc surface 37 and the outer side of the lower end has a first inclined surface 38. The upper part of the inner wall of the toggle block 33 is provided with a second L-shaped plate 39 and the lower part is provided with an insert block 40. The lower end of the second L-shaped plate 39 is provided with a second inclined surface 41 that can abut against the transition arc surface 37. The insert block 40 is provided with a third inclined surface 42 that can abut against the first inclined surface 38. The lower end of the button 35 is provided with a spring 43 groove. The spring 43 groove is provided with a spring 43 that abuts against the third sliding groove 31. The upper end of the button 35 is provided with an indicator mark.

[0021] In this embodiment, pressing the two buttons 35 can cause the lever 33 to slide back and forth in the third slide groove 31. The lever 33 can cause the handle 25 to swing back and forth. The handle 25 can cause the push plate 10 to slide back. The push plate 10 causes the moving spring assembly 7 to swing back and forth, so that the moving contact 5 contacts or separates from the stationary contact 4, thereby realizing the opening and closing control. The indicator mark indicates the state of the contactor according to the different positions of the button 35 when it is raised or lowered. During assembly, the push plate 10 is placed in the first slide groove 8 and the moving spring assembly 7 is inserted into the opening 11. Then, the handle 25 is sleeved in the sleeve 24, so that the upper end of the handle 25 is inserted into the third slot 34 and the lower end is inserted into the first slot 17. The assembly is simple and convenient. Specifically, when the rear button 35 is pressed, the second L-shaped plate 39 of the button 35 moves downward, so that the second inclined surface 41 abuts against the transition arc surface 37 of the first L-shaped plate 36 at the rear end of the lever 33 and applies pressure to the lever 33. The second inclined surface 41 and the transition arc surface 37 cooperate to move the lever 33 backward. At the same time, the insert 40 of the rear button 35 is inserted into the lower part of the first L-shaped plate 36 at the rear end of the lever 33 to complete the positioning of the rear button 35 and prevent the spring 43 from pushing the rear button 35 up. During the backward movement of the lever 33, the transition arc surface 37 of the first L-shaped plate 36 at its front end abuts against the front button 35 and applies pressure to it. With the action of the spring 43, the front button 35 moves upward. During the upward movement of the front button 35, the third inclined surface 42 of the insert 40 abuts against the first inclined surface 38, giving the lever 33 a backward force to prevent the lever 33 from moving forward.
