Technical Field

[0002] A relay is an automatic switching element with isolation function. In a circuit, it plays a role in automatic adjustment, safety protection, and circuit switching. It can expand the control range, control large current operation with small current, and amplify and integrate signals to realize automatic, remote control, and monitoring functions.

[0003] When a relay is energized, the moving iron core may shift radially under the influence of magnetic force, causing the axis of the moving iron core to form an angle with the axis of the magnetic cylinder. This shift directly affects the magnetic circuit stability of the relay, ultimately resulting in a decrease in the relay's sensitivity and an inability to accurately respond to control signals. Utility Model Content

The buffer assembly includes a mounting plate installed inside the mounting slot, a shock-absorbing spring disposed on the top of the mounting plate, a piston rod installed in the middle of the top of the mounting plate, and a piston cylinder connected to the outside of the piston rod.

[0006] Preferably, the stationary contacts and the moving contacts are symmetrically distributed from left to right, and there is a one-to-one correspondence between the stationary contacts and the moving contacts.

[0007] Preferably, the centers of the fixing hole, through hole and limiting hole coincide, and the top of the fixing hole is provided with a chamfer structure.

[0008] Preferably, both the slide rail and the slider are T-shaped structures, and the slider is installed inside the slide rail.

[0009] Preferably, the bottom of the buffer assembly is mounted on the top of the yoke plate, and the top is mounted on the bottom of the connecting plate.

[0010] Preferably, the damping spring, piston rod, and piston cylinder are combined to form a damper.

[0011] The beneficial effects of this utility model are: This invention improves the magnetic circuit stability of the relay by setting a limiting device inside the relay to limit the movement of the moving iron core, so that the moving iron core can only move in a straight line in the vertical direction, avoiding radial deviation.

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] A relay moving iron core moving guide structure, according to Figures 1-4 As shown, it includes a mounting component 1, a limiting component 2 installed inside the mounting component 1, and a buffer component 3 installed inside the mounting component 1; Mounting assembly 1 includes a relay body 101 connected to the outside of the limiting assembly 2, a stationary contact 102 mounted on the top of the relay body 101, mounting holes 103 at the left and right ends of the relay body 101, a fixing block 104 located in the middle of the bottom inside the relay body 101, a fixing hole 105 located on the top of the fixing block 104, a yoke plate 106 located in the middle inside the relay body 101, a through hole 107 located in the middle of the top of the yoke plate 106, and a mounting groove 108 located on the top of the yoke plate 106. The limiting component 2 includes a movable platform 201 installed inside the mounting hole 103, a slide rail 202 opened on the right side of the movable platform 201, a limiting rod 203 installed inside the slide rail 202, sliders 204 arranged on the left and right sides of the limiting rod 203, a limiting hole 205 opened in the middle of the top of the limiting rod 203, a moving iron core body 206 installed inside the limiting hole 205, a connecting plate 207 arranged on the top of the moving iron core body 206, and a moving contact 208 arranged on the top of the connecting plate 207. The buffer assembly 3 includes a mounting plate 301 installed inside the mounting groove 108, a shock-absorbing spring 302 disposed on the top of the mounting plate 301, a piston rod 303 installed in the middle of the top of the mounting plate 301, and a piston cylinder 304 connected to the outside of the piston rod 303.

[0016] according to Figures 1-3 As shown, the stationary contact 102 and the moving contact 208 are symmetrically distributed from left to right, and there is a one-to-one correspondence between the stationary contact 102 and the moving contact 208.

[0017] It should be noted that the stationary contact 102 and the moving contact 208 are symmetrically distributed on the left and right sides, which can make the moving contact 208 bear the force evenly, offset the radial force to avoid displacement, and ensure that the stationary contact 102 and the moving contact 208 fit tightly.

[0018] according to Figures 1-3 As shown, the centers of the fixing hole 105, the through hole 107 and the limiting hole 205 coincide, and the top of the fixing hole 105 is provided with a chamfer structure.

[0019] It should be noted that by aligning the centers of the fixing hole 105, the through hole 107, and the limiting hole 205, the moving iron core body 206 can be subjected to uniform force, and the jamming and wear of the moving iron core body 206 during its up-and-down movement can be reduced, thus extending the life of the moving iron core body 206.

[0020] according to Figure 1 and Figure 3 As shown, both the slide rail 202 and the slider 204 are T-shaped structures, and the slider 204 is installed inside the slide rail 202.

[0021] It should be noted that the T-shaped interlocking design can limit the multi-directional displacement of the slider 204, prevent wobbling or derailment, and improve stability; and because the contact area is relatively large, it can evenly distribute the force and enhance the load-bearing capacity.

[0022] according to Figures 1-4 As shown, the bottom of the buffer assembly 3 is mounted on the top of the yoke plate 106, and the top is mounted on the bottom of the connecting plate 207.

[0023] It should be noted that the buffer assembly 3 can reduce the impact force of the connecting plate 207 on the yoke plate 106, thereby reducing the damage to the connecting plate 207.

[0024] according to Figure 1 and Figure 4 As shown, the shock absorber is composed of the shock absorber spring 302, piston rod 303 and piston cylinder 304.

[0025] It should be noted that the cooperation between the piston rod 303 and the piston cylinder 304 can provide precise guidance, preventing lateral displacement or twisting of the damping spring 302 when it is compressed or extended, and ensuring a stable and orderly buffering process.

[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
