Description

Technical Field

[0001] The utility model relates to the technical field of relays, in particular to an armature installation structure and a relay. Background Art

[0002] A relay is an electronic control device with a control system (also known as an input circuit) and a controlled system (also known as an output circuit). It is usually used in automatic control circuits. In fact, it is an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays the role of automatic regulation, safety protection, and circuit conversion in the circuit.

[0003] The relay uses the on-off of the electromagnetic system to realize the on-off of the contact assembly. Specifically, when the power is on, the iron core attracts the armature to push the contact assembly to conduct. When the power is off, the moving spring of the contact assembly resets to disconnect the contact assembly and push the armature to reset. However, the resetting force of the moving spring is small, and it is difficult to ensure the smooth disconnection of the contact assembly and the rapid and accurate reset of the armature. In addition, when the relay is hit or vibrated, the armature is easily displaced, causing the relay to not work stably. Utility Model Content

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0034] The utility model provides a relay, referring to Figure 1 and Figure 2 The relay body structure includes a housing 4 and a relay body structure, wherein the housing 4 is provided with an inner cavity with a receiving function. Specifically, the housing 4 includes an upper cover 41 and a base 42, wherein the upper cover 41 covers the base 42 to form an inner cavity with a receiving function between the upper cover 41 and the base 42, and the relay body structure is provided in the inner cavity of the housing 4.

[0035] See also Figure 2 The main structure of the relay includes a contact assembly 5, a pusher 6 and an electromagnetic assembly 7. The electromagnetic assembly 7 is connected to the contact assembly 5 through the pusher 6. The on and off of the electromagnetic assembly 7 can control the on and off of the contact assembly 5 through the pusher 6.

[0036] See also Figure 3 The electromagnetic assembly 7 includes a coil assembly 71, a yoke 1, and an armature 2. The coil assembly 71 is arranged horizontally, the yoke 1 is fixed to the left side of the coil assembly 71, and the bottom end of the yoke 1 extends toward the bottom of the coil assembly 71 to form an extension portion, the extension portion is located below the coil assembly 71, and the left end of the extension portion is located below the left side of the coil assembly 71, and the right end of the extension portion is located below the right side of the coil assembly 71. The armature 2 is vertically arranged on the right side of the coil assembly 71, and the bottom end of the armature 2 is connected to the right end of the extension portion, and the rotation axis of the armature 2 is formed at the connection between the two.

[0037] The top of the armature 2 exceeds the top of the coil assembly 71 . The pusher 6 is disposed laterally above the coil assembly 71 , and the right end of the pusher 6 is connected to the top of the armature 2 .

[0038] The contact assembly 5 is arranged on the left side of the electromagnetic assembly 7. The contact assembly 5 includes a movable spring 51, a first static spring 52 and a second static spring 53. The movable spring 51 is arranged between the first static spring 52 and the second static spring 53. The first static spring 52 is arranged close to the electromagnetic assembly 7, and the second static spring 53 is arranged away from the electromagnetic assembly 7. The first static spring 52 is provided with a normally closed contact 521 facing the movable spring 51, and the movable spring 51 is provided with a first movable contact 511 adapted to the normally closed contact 521 facing the first static spring 52. The second static spring 53 is provided with a normally open contact 531 facing the movable spring 51, and the movable spring 51 is provided with a second movable contact 512 adapted to the normally open contact 531 facing the second static spring 53. The left end of the pusher 6 is connected to the movable spring 51 and does not contact the first static spring 52.

[0039] In the initial state, the contact assembly 5 is in the disconnected state, and the first moving contact 511 of the moving spring 51 is closed with the normally closed contact 521. When the electromagnetic assembly 7 is energized, the coil assembly 71 attracts the armature 2, and the armature 2 rotates counterclockwise around the rotating shaft so that the upper part of the armature 2 fits the right end of the coil assembly 71. At this time, the armature 2 drives the pusher 6 to move leftward, and the pusher 6 pushes the moving spring 51 to move leftward until the second moving contact 512 and the normally open contact 532 are closed, and the contact assembly 5 is turned on. When the electromagnetic assembly 7 is de-energized, the coil assembly 71 has no attraction force on the armature 2, so that the pusher 6 has no pushing force on the moving spring 51, and the moving spring 51 rebounds until the first moving contact 511 and the normally closed contact 521 are closed, and pushes the pusher 6 to move rightward, and drives the armature 2 to reset and separate from the coil assembly 71.

[0040] However, the rebound resetting force of the movable spring 51 is small, which makes it difficult to ensure the smooth disconnection of the contact assembly 5 and the rapid and accurate resetting of the pusher 6 and the armature 2. In addition, only the bottom end of the armature 2 is fixed to the yoke 1. When the relay is hit or vibrated, the armature 2 is easily displaced, causing the relay to fail to work stably.

[0041] To this end, the utility model also provides an armature installation structure, see Figure 4 , Figure 5 and Figure 6 , which comprises a yoke 1, an armature 2 and a reset member 3. The yoke 1 is fixedly arranged. The armature 2 comprises an armature body 21 vertically arranged on one side of the yoke 1, the bottom end of the armature body 21 is bent toward the bottom of the yoke 1 to form a bending portion 22, and the connection between the armature body 21 and the bending portion 22 is arranged in contact with the bottom end of the yoke 1 corresponding thereto to form a rotating shaft of the armature 2. The reset member 3, the armature 2 is arranged between the yoke 1 and the reset member 3, the reset member 3 comprises a reset bracket 31, and the reset bracket 31 is provided with an elastic first tongue piece 32 and a second tongue piece 33, the first tongue piece 32 is connected to the side of the armature body 21 facing away from the yoke 1, the second tongue piece 33 is connected to the bottom of the bending portion 22, and the force exerted by the second tongue piece 33 on the armature 2 is opposite to the force exerted by the yoke 1 on the armature 2.

[0042] When the electromagnetic assembly 7 is powered on to rotate the armature 2 counterclockwise around the rotating shaft, the second tongue piece 33 is squeezed, so that when the electromagnetic assembly 7 is powered off, the deformation reaction force of the second tongue piece 33 can push the armature 2 to quickly reset. In addition, the second tongue piece 33 provides an upward force to the armature 2 to prevent the armature 2 from falling downward when it is vibrated or impacted. The bent portion 22 can be hooked at the bottom of the yoke 1 to prevent the armature 2 from moving upward when it is vibrated or impacted. The first tongue piece 32 is connected to the side of the armature body 21 that is away from the yoke 1. The first tongue piece 32 can cooperate with the yoke 1 to prevent the armature 2 from moving left and right when it is vibrated or impacted.

[0043] Therefore, the utility model can prevent the armature 2 from being disengaged from the yoke 1 due to impact or vibration displacement by hooking the bending portion 22 at the bottom end of the yoke 1, connecting the first tongue piece 32 to the side of the armature body 21 facing away from the yoke 1, and connecting the second tongue piece 33 to the bottom of the bending portion 22, thereby limiting the armature 2 and ensuring that the rotating shaft of the armature 2 is always at the contact position between the connection between the armature body 21 and the bending portion 22 and the corresponding bottom end of the yoke 1. In addition, the force exerted by the second tongue piece 33 on the armature 2 is opposite to the force exerted by the yoke 1 on the armature 2, and the reaction force of the second tongue piece 33 due to deformation when power is on can assist in accelerating the reset of the armature when power is off. Therefore, the armature mounting structure of the utility model is arranged in the relay to improve the shock resistance and working stability of the relay.

[0044] Specifically, the yoke 1 includes a horizontal section 11 and a vertical section 12, and one side of the horizontal section 11 is connected to the bottom of the vertical section 12 to form an L-shaped structure. The horizontal section 11 is arranged below the coil assembly 71, and the vertical section 12 is fixed to the left end of the coil assembly 71.

[0045] The armature body 21 is arranged on the side of the horizontal section 11 away from the vertical section 12, the bending part 22 is arranged at the bottom of one end of the horizontal section 11 away from the vertical section 12, and the connection between the armature body 21 and the bending part 22 is arranged in contact with the bottom end of the corresponding horizontal section 11 to form the rotation axis of the armature 2. That is, the armature body 21 is arranged on the right side of the coil assembly 71, and the bending part 22 extends from the bottom end of the armature body 21 to the bottom of the horizontal section 11, so that the connection between the armature body 21 and the bending part 22 is arranged in contact with the right end bottom of the horizontal section 11 to form the rotation axis of the armature 2. As a result, the armature 2 is rotatably connected to the right end bottom of the horizontal section 11 of the yoke 1, and when it is hit or vibrated, the bending part 22 can play a limiting role to prevent the armature 2 from moving upward.

[0046] The reset bracket 31 includes a vertically arranged first section 311, a horizontally arranged second section 312 and a horizontally arranged third section 313. The first section 311 is arranged on the side of the armature body 21 facing away from the yoke 1, that is, the first section 311 is located on the right side of the armature body 21, and the first tongue piece 32 is arranged in the first section 311.

[0047] The second section 312 is disposed below the bending portion 22 . One end of the second section 312 is connected to the bottom of the first section 311 , that is, the right end of the second section 312 is connected to the bottom end of the first section 311 . The second tongue piece 33 is disposed in the second section 312 .

[0048] The third section 313 is fixed at the bottom of the horizontal section 11, and the third section 313 is located on the upper side of the second section 312. Specifically, the third section 313 is located on the upper left side of the second section 312. The second section 312 and the third section 313 are connected by a connecting section 314. The connecting section 314 is arranged horizontally, and the left end of the connecting section 314 is higher than the right end of the connecting section 314.

[0049] Thus, the reset bracket 31 is fixed to the yoke 1 , and the reset bracket 31 limits the armature 2 through the first tongue piece 32 and the second tongue piece 33 and accelerates the reset of the auxiliary armature 2 .

[0050] The first tongue piece 32 is vertically inclined from the first section 311 to the armature body 21, the upper end of the first tongue piece 32 is connected to the first section 311, and the lower end of the first tongue piece 32 is connected to the side of the armature body 21 facing away from the yoke 1. The first tongue piece 32 has a limiting effect on the armature body 21. When the armature 2 is hit or vibrated so that the armature 2 has a tendency to move to the right, the armature 2 squeezes the reaction force of the first tongue piece 32 to deform and prevent the armature 2 from moving to the right. In combination with the transverse section 11 of the yoke 1, it can prevent the armature 2 from shaking to the left. Of course, the resistance of the transverse section 11 of the yoke 1 to the yoke 2 cannot overcome the suction force of the coil assembly 71 on the armature 2 when it is energized, so as to ensure the smooth conduction of the contact assembly 5.

[0051] Preferably, the side of the armature body 21 facing away from the yoke 1 is provided with a limiting groove 23, and the first tongue piece 32 is connected to the limiting groove 23. That is, the lower end of the first tongue piece 32 is connected to the limiting groove 23, and the limiting groove 23 has a limiting function, which can prevent the first tongue piece 32 from being separated from the armature body 21 due to impact or vibration, so as to ensure the limiting effect of the first tongue piece 32.

[0052] More preferably, the limiting groove 23 includes a bottom inner wall 231 located at the bottom end of the limiting groove 23 and a bottom wall 232 close to the yoke 1, and the first tongue piece 32 is connected to the connection between the bottom inner wall 231 and the bottom wall 232. The connection between the bottom inner wall 231 and the bottom wall 232 of the limiting groove 23 further strengthens the limiting effect on the lower end of the first tongue piece 32, and this arrangement enables the first tongue piece 32 to prevent the armature 2 from shifting upward or even forward or backward, thereby improving the limiting function of the first tongue piece 32.

[0053] The second tongue piece 33 is vertically inclined from the second section 312 to the bending portion 22, the upper part of the second tongue piece 33 is connected to the bottom of the bending portion 22, the lower end of the second tongue piece 33 is connected to the second section 312, the lower end of the second tongue piece 33 is arranged closer to the connecting section 314 than the upper part thereof, and the vertical projection of the rotation axis of the armature 2 is located between the vertical projection of the lower end of the second tongue piece 33 and the vertical projection of the upper part of the second tongue piece 33. On the one hand, the second tongue piece 33 has a limiting effect on the armature 2, when the armature 2 has a tendency to move downward due to impact or vibration, the armature 2 squeezes the second tongue piece 33 so that the deformation reaction force prevents the armature 2 from moving downward, and cooperates with the hook of the bending portion 22 arranged at the bottom of the horizontal section 11 to prevent the armature 2 from shifting vertically. On the other hand, when the electromagnetic assembly 7 is energized to make the armature 2 rotate counterclockwise around the rotating shaft, the second tongue piece 33 will be squeezed, so that when the electromagnetic assembly 7 is de-energized, the deformation reaction force of the second tongue piece 33 can push the armature 2 to quickly reset, thereby driving the pushing member 6 to reset, so as to drive the moving spring piece 51 to reset to the right until the first moving contact 511 and the normally closed contact 521 are closed, thereby realizing the smooth disconnection of the contact assembly 5.

[0054] It is worth noting that the upper part of the second tongue piece 33 is connected to the bottom of the bending portion 22, which does not necessarily mean that the upper end of the second tongue piece 33 is connected to the bottom of the bending portion 22, as long as the electromagnetic component 7 is energized so that the second tongue piece 33 can be squeezed when the armature 2 rotates counterclockwise around the rotating axis.

[0055] The side of the bent portion 22 facing away from the yoke 1 is closer to the yoke 1 than the side of the armature body 21 facing away from the yoke 1. On the one hand, the lateral distance of the bent portion 22 is shorter, which can reduce the volume and length of the second tongue 33 to a certain extent. On the other hand, the shorter lateral distance of the bent portion 22 is conducive to shortening the lateral distance of the second section 312, so that the distance between the first section 311 and the armature body 21 is reduced, which is conducive to reducing the volume and length of the second tongue 33. In addition, the reduced distance between the reset bracket 31 and the armature 2 can reduce the shaking space of the armature 2, and the limiting effect is better.

[0056] In addition, the third section 313 is provided with a vertically penetrating through hole 3131, and a fixing member 13 adapted to the through hole 3131 extends downward from the bottom surface of the cross section 11. The fixing member 13 is fixed through the through hole 3131 to fix the third section 313 to the bottom of the cross section 11, thereby fixing the reset member 3 to the yoke 1.

[0057] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
