Description

Technical Field

[0001] This utility model relates to the field of contactor short-circuit rings, specifically a cantilever concave contactor short-circuit ring. Background Technology

[0002] The cantilever recessed contactor short-circuit ring is a key component in AC contactors used to eliminate armature vibration and noise. Its design combines the basic principles of short-circuit rings with the optimization of the cantilever recessed structure to improve the performance and reliability of the contactor.

[0003] Currently, contactor rings need to engage during operation, but during prolonged engagement, collisions can occur between the two components. Repeated collisions increase the damage rate, thereby reducing the service life of the contactor rings. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide a short-circuit ring for a cantilever concave contactor, thereby resolving the issues raised in the background section.

[0005] To achieve the above objectives, this utility model proposes a short-circuit ring for a cantilever concave contactor, including a housing, the top of which is fitted with a top cover; The housing has an internal protective mechanism, which includes a coil frame, a dynamic contact ring, a rubber plate, a rubber pad, a groove, and a static contact ring. The coil frame is installed inside the housing, and the static contact ring is installed at the bottom of the coil frame. The top of the static contact ring has two grooves, and the inner walls of the two grooves are fitted with rubber pads. The top of the coil frame is slidably connected to the dynamic contact ring, and the bottom of the dynamic contact ring is fixedly installed with a rubber plate that matches the groove.

[0006] In one example, the inner wall of the coil frame is provided with grooves on both sides, and the inner walls of the two grooves are slidably connected with sliders fixed to the dynamic contact ring.

[0007] In one example, a return spring is installed at the bottom of the inner wall of the dynamic contact ring, and the other end of the return spring is connected to the coil frame.

[0008] In one example, four fixing rods are installed on the bottom of the inner wall of the housing. All four fixing rods are threadedly connected to the coil frame, and each of the four fixing rods has a threaded groove at its top.

[0009] In one example, the top four corners of the cover are threaded with screws, which all penetrate and extend into the outer shell, and the bottom ends of the screws inside the outer shell are threadedly connected to threaded grooves.

[0010] In one example, the outer ring of the coil holder is wound with a coil.

[0011] The short-circuit ring of the cantilever concave contactor proposed in this utility model can bring the following beneficial effects: 1. This cantilever recessed contactor short-circuit ring, when energized, generates magnetic force in the coil on the coil frame, causing the dynamic contact ring and static contact ring to attract each other, which in turn causes the rubber plate to descend and compresses the return spring. When the rubber plate comes into contact with the rubber pad in the groove, it prevents collisions during attraction, thus avoiding damage. By setting a protective mechanism, it can protect the two when they are attracted, thereby increasing its service life.

[0012] 2. The short-circuit ring of the cantilever concave contactor is provided by placing a static contact ring inside the housing, then installing the bottom of the coil frame on the static contact ring, then threading the fixing rod to the coil frame and threading its bottom end to the housing, and then threading the screw installed on the top cover to the threaded groove at the top of the fixing rod, which can fix the top cover and the housing.

[0015] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0016] like Figures 1-3 As shown, an embodiment of this utility model proposes a cantilever concave contactor short-circuit ring, including a housing 1, and a top cover 2 is installed on the top of the housing 1. The housing 1 has a protective mechanism inside, which includes a coil frame 12, a dynamic contact ring 10, a rubber plate 9, a rubber pad 8, a groove 7, and a static contact ring 6. The coil frame 12 is installed inside the housing 1. The static contact ring 6 is installed at the bottom of the coil frame 12. Two grooves 7 are opened at the top of the static contact ring 6. Rubber pads 8 are installed on the inner walls of the two grooves 7. The dynamic contact ring 10 is slidably connected to the top of the coil frame 12. The bottom of the dynamic contact ring 10 is fixedly installed with a rubber plate 9 that matches the groove 7.

[0017] Specifically, the inner walls of the coil frame 12 are provided with sliding grooves 14 on both sides. The inner walls of the two sliding grooves 14 are slidably connected with sliders 15 that are fixed to the dynamic contact ring 10. The sliders 15 are installed through the sliding grooves 14 and the dynamic contact ring 10 is limited when it moves.

[0018] Specifically, a reset spring 11 is installed at the bottom of the inner wall of the dynamic contact ring 10. The other end of the reset spring 11 is connected to the coil frame 12. The reset spring 11 performs a reset action under the action of potential energy, and drives the dynamic contact ring 10 to perform a reset action.

[0019] Specifically, four fixing rods 4 are installed on the bottom of the inner wall of the outer casing 1. All four fixing rods 4 are threadedly connected to the coil frame 12. The top of each of the four fixing rods 4 is provided with a threaded groove 5. The coil frame 12 is fixed by the fixing rods 4, and the coil frame 12 winds the coil 13.

[0020] Specifically, screws 3 are threaded to the four corners of the top of the cover 2. The screws 3 penetrate and extend into the outer shell 1. The bottom of the screws 3 inside the outer shell 1 is threaded to the threaded groove 5. The screws 3 are threaded to the threaded groove 5 and can fix the cover 2 and the outer shell 1.

[0021] Specifically, the outer ring of the coil frame 12 is wound with a coil 13.

[0022] Working principle: A static contact ring 6 is placed inside the outer casing 1. The bottom of the coil frame 12 is then installed on the static contact ring 6. The fixing rod 4 is threaded to the coil frame 12, and its bottom end is threaded to the outer casing 1. The screw 3 installed on the upper cover 2 is then threaded to the threaded groove 5 at the top of the fixing rod 4, which can fix the upper cover 2 and the outer casing 1. When energized, the coil 13 on the coil frame 12 generates magnetic force, which causes the dynamic contact ring 10 to attract the static contact ring 6. This causes the rubber plate 9 to descend and compresses the return spring 11. When the rubber plate 9 is in contact with the rubber pad 8 in the groove 7, the static contact ring 6 and the dynamic contact ring 10 attract each other. When the power is off, the magnetic force disappears, the return spring 11 performs a reset action, which causes the dynamic contact ring 10 to perform a reset action and separates the dynamic contact ring 10 from the static contact ring 6. This allows for limiting the attraction and separation of the dynamic contact ring 10, preventing collisions during attraction.
