relay

Abstract

This application discloses a relay, relating to the field of electrical equipment technology. The relay provided by this application includes a normally closed component, a guide plate, and an emergency stop button. The guide plate cooperates with the normally closed component, is slidable along a first direction, and has a mating portion. The emergency stop button is slidable along a second direction and is used to receive a pressing operation. The emergency stop button has a pushing surface for cooperating with the mating portion, the pushing surface intersecting the first and second directions. When the emergency stop button receives a pressing operation, the emergency stop button slides along the second direction, and the pushing surface pushes against the mating portion, causing the guide plate to slide along the first direction and disconnect the normally closed component. Thus, when the emergency stop button receives a pressing operation, the direction of the force exerted by the guide plate on the normally closed component is along the second direction. In this way, the normally closed component operates under the action of a force in a single direction, making the control of the normally closed component more reliable and precise.

Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, and more particularly to a relay. Background Technology

[0002] Relays are common components in various intelligent control systems. Based on their internally configured normally closed moving and normally closed stationary contacts, relays can be connected to a circuit via these contacts. When a relay is overloaded, the normally closed moving and stationary contacts separate, disconnecting the circuit and protecting it.

[0003] To ensure safer operation of the relay, an emergency stop button is also provided. In case of an emergency requiring an emergency stop, the emergency stop button can be operated to disconnect the circuit connected to the relay.

[0004] However, in the relevant technology, the disconnection between the normally closed moving contact and the normally closed stationary contact is not reliable enough when the emergency stop button is pressed, which leads to emergency stop failure and a series of serious consequences such as equipment damage. Utility Model Content

[0005] This application provides a relay that makes the relay's emergency stop more reliable and reduces the possibility of equipment damage and other consequences.

[0006] In a first aspect, this application provides a relay having intersecting first and second directions. The relay includes a normally closed component, a guide plate, and an emergency stop button. The guide plate cooperates with the normally closed component, is slidable along the first direction, and has a mating portion. The emergency stop button is slidable along the second direction and is used to receive a pressing operation. The emergency stop button has a pushing surface for cooperating with the mating portion, the pushing surface intersecting the first and second directions. When the emergency stop button receives a pressing operation, the emergency stop button slides along the second direction, and the pushing surface pushes against the mating portion, causing the guide plate to slide along the first direction and disconnect the normally closed component.

[0007] In this embodiment, the direction of the force exerted by the guide plate on the normally closed component is along the second direction. Thus, the force on the normally closed component is only along the second direction, causing the normally closed component to operate under the action of a force in a single direction. This makes the control of the normally closed component more reliable and precise, thereby reducing the possibility of relay emergency stop failure, which could lead to damage to the relay or even other components in the relay's circuit.

[0008] Optionally, the relay also includes a normally open component, with the normally open and normally closed components spaced apart along a first direction. The guide plate also mates with the normally open component. When the emergency stop button is pressed, the guide plate can also connect to the normally open component.

[0009] In this embodiment, when the emergency stop button is pressed, the guide plate can not only control the normally closed component to open, but also control the normally open component to close, thus facilitating the implementation of other functions while the power is off.

[0010] Optionally, the normally open component includes a mating normally open moving contact and a normally open stationary contact, and the normally closed component includes a mating normally closed moving contact and a normally closed stationary contact. The guide plate mates with the normally open moving contact and the normally closed moving contact respectively. When the emergency stop button receives a press operation, the guide plate can drive the normally open moving contact and the normally closed moving contact to move, so that the normally open moving contact is connected to the normally open stationary contact, and the normally closed moving contact is separated from the normally closed stationary contact.

[0011] With the above settings, the guide plate can apply force to the normally open moving contact and the normally closed moving contact to achieve the switching between the normally open component and the normally closed component state.

[0012] Optionally, the guide plate includes a body, a first push rod, and a second push rod. The first and second push rods are spaced apart on the body along a first direction, and a mating part is disposed on the body. The normally open moving contact and the normally closed moving contact are close to each other, or the normally open stationary contact and the normally closed stationary contact are close to each other. The first push rod is located between the normally open moving contact and the normally open stationary contact, and the second push rod is located between the normally closed moving contact and the normally closed stationary contact. The guide plate can drive the normally open moving contact to move via the first push rod and drive the normally closed moving contact to move via the second push rod. When the emergency stop button receives a press operation, the second push rod pushes against the normally closed moving contact, and the first push rod separates from the normally open moving contact.

[0013] With the above configuration, the guide plate can cooperate with the normally open component via the first push rod and with the normally closed component via the second push rod. The first push rod is located between the normally open moving contact and the normally open stationary contact, allowing the guide plate to drive the normally open moving contact to move. The second push rod is located between the normally closed moving contact and the normally closed stationary contact, allowing the guide plate to drive the normally closed moving contact to move.

[0014] Optionally, the emergency stop button has an operating end for receiving a pressing operation. The body includes a base plate and an actuating block, with a first push rod and a second push rod connected to the base plate. The actuating block is connected to one end of the base plate in a first direction, and in the direction from one end of the base plate to the other, the actuating block has opposing first and second sides. A mating portion is formed on the surface of the second side facing the operating end, or a mating portion is formed on the surface of the first side facing the operating end. In the second direction, the pushing surface is opposite to the mating portion.

[0015] In the embodiments of this application, the mating parts can be configured in different ways, which makes the configuration of the main body and the emergency stop button more flexible.

[0016] Optionally, the mating part can be a curved surface.

[0017] Thus, the contact between the pushing surface and the mating part is a surface contact. When the emergency stop button pushes against the mating part, the pressure between the emergency stop button and the mating part can be reduced, and the stress between the emergency stop button and the mating part can be dispersed, thereby reducing the possibility of damage to the mating part and / or the emergency stop button, and making the pushing process of the emergency stop button against the mating part smoother.

[0018] Optionally, the normally open moving contact includes a normally open support and a normally open moving contact. The normally open moving contact is located on the side of the normally open support facing the normally open stationary contact, and the position of the normally open moving contact near the normally open moving contact mates with the guide plate. The normally closed moving contact includes a normally closed support and a normally closed moving contact. The normally closed moving contact is located on the side of the normally closed support facing the normally closed stationary contact, and the position of the normally closed moving contact near the normally closed moving contact mates with the guide plate.

[0019] In this way, when the emergency stop button drives the guide plate to slide based on the pressing operation, the guide plate can directly apply force to the normally open support near the normally open moving contact and the normally closed support near the normally closed moving contact, which can facilitate the switching of the state of the normally open component and the normally closed component.

[0020] Optionally, the relay also includes a base and a reset element. The normally open component, normally closed component, guide plate, and emergency stop button are all disposed on the base. The reset element is hinged to the guide plate, and an elastic element is disposed between the reset element and the base. When the guide plate slides, the reset element can rotate relative to the guide plate and compress the elastic element. Based on the action of the elastic element, the reset element can control the relay to reset after the emergency stop button is released, thereby disconnecting the normally open component and connecting the normally closed component.

[0021] Thus, after the emergency is released, the reset component can drive the guide plate to slide and disconnect the normally open component, and connect the normally closed component.

[0022] Optionally, the emergency stop button includes a button and a push block. The push block is connected to one side of the button in the first direction, and a push surface is provided on the push block. The button is used to receive a pressing operation.

[0023] In this way, the button can apply force to the guide plate through the push block, so that the guide plate can slide in the first direction.

[0024] Optionally, the button and push block are integrally molded.

[0025] This approach simplifies the manufacture of the emergency stop button and also strengthens the connection between the push block and the button, reducing the likelihood of the push block detaching after prolonged use. Attached Figure Description

[0044] The relay 100 provided in the embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0045] Reference Figure 1 , Figure 2 and Figure 3 As shown, this application provides a relay 100, which has intersecting first direction X and second direction Y. The relay 100 includes a normally closed component 10, a guide plate 20, and an emergency stop button 30. The guide plate 20 cooperates with the normally closed component 10, is slidable along the first direction X, and has a mating portion 201. The emergency stop button 30 is slidable along the second direction Y and is used to receive a pressing operation. The emergency stop button 30 has a pushing surface 301 for cooperating with the mating portion 201, and the pushing surface 301 intersects the first direction X and the second direction Y. When the emergency stop button 30 receives a pressing operation, the emergency stop button 30 can slide along the second direction Y, and the pushing surface 301 can push against the mating portion 201, causing the guide plate 20 to slide along the first direction X and disconnect the normally closed component 10.

[0046] In this embodiment, the relay 100 includes a normally closed component 10, which is in the ON state under normal conditions. When connecting the relay 100 to a circuit, the normally closed component 10 can be connected to the circuit to turn it on.

[0047] The relay 100 also includes a guide plate 20 and an emergency stop button 30. The guide plate 20 is slidably disposed along a first direction X, and the emergency stop button 30 is slidably disposed along a second direction Y. The guide plate 20 and the emergency stop button 30 are engaged with a push surface 301 through a mating part 201. The push surface 301 intersects the first direction X and the second direction Y, therefore, the push surface 301 is inclined.

[0048] Thus, when the emergency stop button 30 receives a press operation, the emergency stop button 30 can slide along the second direction Y. At this time, the push surface 301 can also slide along the second direction Y, thereby engaging with the mating part 201 and applying force to the guide plate 20 through the mating part 201. Since the push surface 301 is inclined in this application, the force applied by the push surface 301 to the mating part 201 has two components: one along the first direction X and the other along the second direction Y.

[0049] In this configuration, the mating part 201 can slide along the first direction X based on the component force along the first direction X, thereby causing the guide plate 20 to slide as a whole along the first direction X. Since the guide plate 20 is mated with the normally closed component 10, the guide plate 20 also exerts a force on the normally closed component 10 during the sliding process along the first direction X, thereby controlling the state of the normally closed component 10.

[0050] In summary, in this embodiment, when there is an emergency requiring the circuit containing relay 100 to be disconnected, the emergency stop button 30 can be pressed, allowing the emergency stop button 30 to control the normally closed component 10 to open via the guide plate 20. Thus, the emergency stop button 30 works in conjunction with the guide plate 20 to control the normally closed component 10. Since the guide plate 20 is slidably disposed along the second direction Y, the direction of the force exerted by the guide plate 20 on the normally closed component 10 is also along the second direction Y. Therefore, the force on the normally closed component 10 is only along the second direction Y, causing the normally closed component 10 to operate under the action of a force in a single direction. As a result, the control of the normally closed component 10 in this application is more reliable and precise, thereby reducing the possibility of relay 100 emergency stop failure leading to damage to relay 100 or even other components in the circuit containing relay 100.

[0051] It should be noted that the first direction X intersects with the second direction Y, and the first direction X and the second direction Y can have an angle of approximately 90°, so that the sliding of the emergency stop button 30 can drive the guide plate 20 to slide in the other direction. In the embodiments of this application, the angle can be 75°, 80°, 87°, or 94°, etc. As a preferred embodiment, the first direction X and the second direction Y can be perpendicular to each other. The specific angle value between the first direction X and the second direction Y is not specifically limited in the embodiments of this application.

[0052] To make the solution and beneficial effects of this application clearer, this application will be described in detail in conjunction with relevant technologies.

[0053] In related technologies, such as Figure 4 As shown, the relay also includes a normally closed component and an emergency stop button 1. The normally closed component includes a moving contact 2 and a stationary contact 3. The moving contact 2 can contact or separate from the stationary contact 3, allowing the relay to connect or disconnect its circuit. The moving contact 2 has a certain degree of elasticity, and a push arm 4 is provided in the middle of the moving contact 2. The emergency stop button 1 is located on the side of the moving contact 2 where the push arm 4 is located.

[0054] With relays Figure 4 Taking the illustrated configuration as an example, the following detailed explanation is provided: When the emergency stop button 1 is pressed, it slides downwards, applying force to the push arm 4. This causes the moving contact 2 to move away from the stationary contact 3, separating it from the stationary contact 3, thus achieving emergency stop control of the relay 100. During this process, the force exerted by the emergency stop button 1 on the push arm 4 has a rightward component and a downward component. The downward component also affects the movement of the moving contact. Specifically, the connection between the push arm 4 and the moving contact 2 can form a fulcrum. The downward component causes the upper side of the moving contact 2 to rotate counterclockwise around the fulcrum, making the upper side of the moving contact 2 closer to the stationary contact 3. This could potentially cause the moving contact 2 and the stationary contact 3 to connect, resulting in unreliable emergency stop control of the relay.

[0055] However, in this embodiment, instead of directly driving the normally closed component 10 to open via the emergency stop button 30, the normally closed component 10 is opened by applying force through the guide plate 20, thus achieving emergency stop control of the normally closed component 10. The sliding direction of the guide plate 20 is the first direction X. Therefore, the force exerted by the guide plate 20 on the normally closed component 10 is only along the first direction X, with no component force in other directions. This makes the pushing action of the emergency stop button 30 on the normally closed component 10 via the guide plate 20 more reliable, reducing the possibility of other component forces affecting the opening of the normally closed component 10 during the pushing process, thereby making the emergency stop control of the relay 100 by the emergency stop button 30 more reliable.

[0056] In some embodiments, such as Figures 1 to 2 As shown, the relay 100 may further include a normally open component 40, which is spaced apart from the normally closed component 10 along a first direction X. The guide plate 20 also cooperates with the normally open component 40. When the emergency stop button 30 receives a press operation, the guide plate 20 may also be connected to the normally open component 40.

[0057] With the above settings, when the emergency stop button 30 is pressed, its action can control not only the normally closed component 10 but also the normally open component 40. Specifically, after the emergency stop button 30 is pressed, the guide plate 20 exerts force on both the normally open component 40 and the normally closed component 10, thus controlling the states of both components.

[0058] In this embodiment of the application, when the emergency stop button 30 is pressed, the guide plate 20 can not only control the normally closed component 10 to open, but also control the normally open component 40 to close. This makes it easy to achieve other functions while the power is off.

[0059] For example, normally closed component 10 can be connected in the working circuit, while normally open component 40 can be connected in the alarm circuit. Thus, in an emergency, pressing the emergency stop button 30 will open normally closed component 10, disconnecting the working circuit, while normally open component 40 will close, activating the alarm circuit. This allows the alarm circuit to output a warning signal, enabling staff or the control system to record the shutdown, reducing the possibility of confusion later on regarding whether the relay 100 shut down normally or stopped in an emergency, and ensuring the safe operation of the relay 100 and the working circuit.

[0060] In summary, pressing the emergency stop button 30 can simultaneously disconnect the working circuit and connect the alarm circuit, making the alarm circuit connection more timely and convenient, and reducing the possibility of needing to trigger the state switching of the normally open component 40 through other actions.

[0061] Here, this application will provide a detailed explanation of the normally open component 40 and the normally closed component 10 in order to illustrate the state switching process of the normally open component 40 and the normally closed component 10 when the emergency stop button 30 is pressed.

[0062] like Figure 1 As shown, the normally open component 40 may include a normally open moving contact 41 and a normally open stationary contact 42 that cooperate with each other. The normally open moving contact 41 and the normally open stationary contact 42 cooperate with each other. The normally open moving contact 41 can move relative to the normally open stationary contact 42 to contact the normally open stationary contact 42, thereby connecting the normally open component 40, or separating from the normally open stationary contact 42, thereby disconnecting the normally open component 40.

[0063] The normally closed assembly 10 includes a normally closed moving contact 11 and a normally closed stationary contact 12 that cooperate with each other. The normally closed moving contact 11 and the normally closed stationary contact 12 cooperate with each other. The normally closed moving contact 11 can move relative to the normally closed stationary contact 12 to contact the normally closed stationary contact 12, thereby connecting the normally closed assembly 10, or separating from the normally closed stationary contact 12, thereby disconnecting the normally closed assembly 10.

[0064] When relay 100 is operating normally, normally closed component 10 is in the ON state and normally open component 40 is in the OFF state. However, when relay 100 stops due to overload or emergency, normally closed component 10 is in the OFF state and normally open component 40 is in the ON state.

[0065] In this application, the guide plate 20 cooperates with both the normally open component 40 and the normally closed component 10, specifically with the normally open moving contact 41 and the normally closed moving contact 11. When the emergency stop button 30 receives a press operation, the guide plate 20 can drive the normally closed moving contact 11 to move, so that the normally open moving contact 41 is connected with the normally open stationary contact 42, and the normally closed moving contact 11 is separated from the normally closed stationary contact 12.

[0066] In some embodiments, such as Figure 3 , Figure 5 and Figure 6 As shown, the guide plate 20 may include a body 21, a first push rod 22, and a second push rod 23. The first push rod 22 and the second push rod 23 are spaced apart on the body 21 along the first direction X. The mating part 201 is disposed on the body 21 and can be used to receive the force applied by the emergency stop button 30 so as to switch the state of the normally open component 40 and the normally closed component 10.

[0067] The guide plate 20 can cooperate with the normally open component 40 via the first push rod 22 and with the normally closed component 10 via the second push rod 23. In this embodiment, the first push rod 22 is located between the normally open moving contact 41 and the normally open stationary contact 42, and the second push rod 23 is located between the normally closed moving contact 11 and the normally closed stationary contact 12. The guide plate 20 can drive the normally open moving contact 41 to move via the first push rod 22 and drive the normally closed moving contact 11 to move via the second push rod 23.

[0068] In this application, the normally open component 40 and the normally closed component 10 can be arranged in different ways. For example, the normally open moving contact 41 and the normally closed moving contact 11 are close to each other. In this case, the normally open stationary contact 42, the normally open moving contact 41, the normally closed moving contact 11, and the normally closed stationary contact 12 are distributed sequentially in the first direction X. Alternatively, the normally open stationary contact 42 and the normally closed stationary contact 12 are close to each other. In this case, the normally open moving contact 41, the normally open stationary contact 42, the normally closed stationary contact 12, and the normally closed moving contact 11 are distributed sequentially in the first direction X.

[0069] Thus, when the guide plate 20 slides along the first direction X, the action of the guide plate 20 on the normally open moving contact 41 and the action of the guide plate 20 on the normally closed moving contact 11 are different. Here, the normally open assembly 40 and the normally closed assembly 10 are used as examples. Figure 1 The orientation shown is illustrated as an example. When the guide plate 20 slides to the right, the second push rod 23 pushes the normally closed moving contact 11 to the right, causing the normally closed moving contact 11 to move away from the normally closed stationary contact 12. At the same time, the first push rod 22 will slide away from the normally open moving contact 41, canceling the pushing effect on the normally open moving contact 41, which allows the normally open moving contact 41 to move closer to the normally open stationary contact 42.

[0070] Thus, the guide plate 20 slides in one direction, which makes the relative relationship between the normally open moving contact 41 and the normally open stationary contact 42 different from the relative relationship between the normally closed moving contact 11 and the normally closed stationary contact 12, so that the normally open component 40 and the normally closed component 10 can be switched to different states.

[0071] In summary, when the guide plate 20 slides along the first direction X, the first push rod 22 and the second push rod 23 can also slide along the first direction X, so that the first push rod 22 can push the normally open moving contact 41, or the second push rod 23 can push the normally closed moving contact 11, thereby controlling the switching of the state of the normally open component 40 and the normally closed component 10. In this way, when the emergency stop button 30 is pressed, the emergency stop button 30 can easily control the normally open component 40 to be turned on and the normally closed component 10 to be turned off based on the pressing operation.

[0072] In some embodiments, such as Figure 1 , Figure 3 and Figure 6 As shown, the emergency stop button 30 has an operation terminal 302. The emergency stop button 30 can receive a pressing operation through the operation terminal 302 to control the relay 100 to perform an emergency stop. The body 21 includes a base plate 211 and an actuating block 212. The actuating block 212 is connected to one end of the base plate 211 in the first direction X. The mating part 201 can be disposed on the actuating block 212 to receive the pushing action of the pushing surface 301.

[0073] The actuating block 212 has opposing first and second sides in the direction from one end to the other on the substrate 211. The mating part 201 can be arranged in different ways, and the following two methods will be described as examples.

[0074] Method 1, such as Figure 3 As shown, a mating part 201 is formed on the second side of the surface facing the operating end 302.

[0075] In relay 100 Figure 3Taking the arrangement shown as an example, the actuating block 212 can be connected to the left side of the guide plate 20. In this case, a mating portion 201 can be formed on the right side of the actuating block 212 facing the operating end 302. At this time, the projection of the pushing surface 301 in the second direction Y is located between the second side and the other end of the substrate 211, allowing the pushing surface 301 and the mating portion 201 to be opposite each other in the second direction Y. Thus, when the pushing surface 301 slides along the second direction Y, it facilitates the engagement of the pushing surface 301 with the mating portion 201, thereby driving the guide plate 20 to slide along the first direction X via the mating portion 201.

[0076] In the second method, a mating portion 201 is formed on the surface of the first side facing the operating end 302. In the second direction Y, the projection of the abutting surface 301 is located on the side of the second side opposite to the substrate 211. That is, the mating portion 201 can also be provided on the side of the actuating block 212 away from the substrate 211. Figure 5 Therefore, the part of the surface on the left side of the action block 212 facing the operating end 302 can also form a mating part 201.

[0077] At this time, the projection of the pushing surface 301 in the second direction Y can be located on the side of the second side away from the other end of the substrate 211. This allows the pushing surface 301 and the mating part 201 to be opposite each other in the second direction Y. When the pushing surface 301 slides along the second direction Y, it is convenient for the pushing surface 301 to cooperate with the mating part 201, thereby driving the guide plate 20 to slide along the first direction X through the mating part 201.

[0078] In some embodiments, the mating portion 201 can be an arc surface. This arc-shaped mating portion 201 allows for surface contact between the abutting surface 301 and the mating portion 201. When the emergency stop button 30 pushes against the mating portion 201, the pressure between the emergency stop button 30 and the mating portion 201 can be reduced, dispersing the stress between them. This reduces the possibility of damage to the mating portion 201 and / or the emergency stop button 30, and makes the pushing process of the emergency stop button 30 against the mating portion 201 smoother.

[0079] It is understood that in this application, the action block 212 can be a square or similar square structure. At the position of the mating part 201, the edges of the action block 212 can be rounded so that the mating part 201 can be an arc surface.

[0080] Of course, the mating part 201 can also be left unrounded, that is, the mating part 201 can retain its original edge setting. In this case, in order to reduce the possibility of damage to the mating part 201 and / or the emergency stop button 30, the mating part 201 can be made of a material with a certain elasticity, and the strength of the emergency stop button 30 can be strengthened.

[0081] In some embodiments, the normally open moving contact 41 may include a normally open support and a normally open moving contact, the normally open moving contact being disposed on the side of the normally open support facing the normally open stationary contact 42. The normally closed moving contact 11 includes a normally closed support and a normally closed moving contact, the normally closed moving contact being disposed on the side of the normally closed support facing the normally closed stationary contact 12.

[0082] Understandably, the normally open moving contact is the part of the normally open moving contact 41 that is used to contact the normally open stationary contact 42 to achieve its cooperation with the normally open stationary contact 42, and the normally closed moving contact is the part of the normally closed moving contact 11 that is used to contact the normally closed stationary contact 12 to achieve its cooperation with the normally closed stationary contact 12.

[0083] Therefore, the normally open moving contact 41 can achieve the closure of the normally open component 40 by contacting the normally open stationary contact 42, and when the normally open component 40 is open, the normally open moving contact can separate from the normally open stationary contact 42. The normally closed moving contact 11 can achieve the closure of the normally closed component 10 by contacting the normally closed stationary contact 12, and when the normally closed component 10 is open, the normally closed moving contact can separate from the normally closed stationary contact 12.

[0084] In the embodiments of this application, such as Figure 1 , Figure 5 and Figure 6 As shown, the normally open moving contact 41, near the normally open moving contact point, mates with the guide plate 20, and the normally closed moving contact 11, near the normally closed moving contact point, mates with the guide plate 20. Thus, the position of the guide plate 20 mates with the normally open component 40 near the normally open moving contact, and the position of the guide plate 20 mates with the normally closed component 10 near the normally closed moving contact. Therefore, when the emergency stop button 30 drives the guide plate 20 to slide based on a pressing operation, the guide plate 20 can directly apply force to the normally open support near the normally open moving contact and the normally closed support near the normally closed moving contact.

[0085] Thus, the position of the guide plate 20 acting on the normally open moving contact 41 is close to the normally open moving contact, and the position of its acting on the normally closed moving contact 11 is also close to the normally closed moving contact, which facilitates the switching of the states of the normally open component 40 and the normally closed component 10. Specifically, in the first direction X, the projection of the first push rod 22 can be close to the normally open moving contact. In this way, the first push rod 22 can apply force to the normally open moving contact 41 through the position on the normally open support close to the normally open moving contact. Similarly, in the first direction X, the projection of the second push rod 23 can be close to the normally closed moving contact, so the second push rod 23 can apply force to the normally closed moving contact 11 through the position on the normally closed support close to the normally closed moving contact.

[0086] For ease of explanation, the end of the normally open moving contact 41 furthest from the normally open moving contact is called the normally open mounting end, and the end of the normally closed moving contact 11 furthest from the normally closed moving contact is called the normally closed mounting end. The normally open moving contact 41 can be installed in the relay 100 through the normally open mounting end, and the normally closed moving contact 11 can be installed in the relay 100 through the normally closed mounting end.

[0087] With the above-described configuration of this application, when the guide plate 20 applies force to the normally open assembly 40 and the normally closed assembly 10, the distance between the point of force application and the normally open mounting end, and the distance between the point of force application and the normally closed mounting end, is relatively large. This allows the guide plate 20 to apply a larger torque to the normally open moving contact 41 and the normally closed moving contact 11, thereby facilitating the rotation of the normally open moving contact 41 around the normally open mounting end to bring it closer to or away from the normally open stationary contact 42, and facilitating the rotation of the normally closed moving contact 11 around the normally closed mounting end to move it away from or closer to the normally closed stationary contact 12.

[0088] In this embodiment of the application, when the emergency stop button 30 receives a press operation, it can facilitate the emergency stop button 30 to drive the guide plate 20 to slide along the second direction Y, thereby facilitating the disconnection of the normally closed component 10 and the connection of the normally open component 40, improving the reliability and convenience of the relay 100 under the action of the emergency stop button 30.

[0089] In the embodiments of this application, such as Figure 1 and Figure 2 As shown, the relay 100 may include a base 50, and normally closed components 10, normally open components 40, a guide plate 20, and an emergency stop button 30, all of which can be mounted on the base 50. Specifically, normally open stationary contacts 42 and normally closed stationary contacts 12 are fixed to the base 50, normally open moving contacts 41 can be connected to the base 50 through a normally open mounting end, and normally closed moving contacts 11 can be connected to the base 50 through a normally closed mounting end. The guide plate 20 is slidably mounted on the base 50 along a first direction X, and the emergency stop button 30 is slidably mounted on the base 50 along a second direction Y.

[0090] In the embodiments of this application, such as Figure 2 and Figure 5 As shown, the relay 100 may also include a reset member 60. In case of emergency contact, the reset member 60 can drive the guide plate 20 to slide, thereby disconnecting the normally open component 40 and connecting the normally closed component 10, thus restoring the working circuit and disconnecting the alarm circuit. The reset member 60 can be hinged to the guide plate 20, and an elastic element 70 is provided between it and the base 50. When the guide plate 20 slides, the reset member 60 can rotate relative to the guide plate 20 and compress the elastic element 70. Based on the action of the elastic element 70, the reset member 60 can control the relay 100 to reset after the emergency stop button 30 is depressed, thereby disconnecting the normally open component 40 and connecting the normally closed component 10.

[0091] In this way, the reset member 60 can rotate relative to the guide plate 20 about its hinged position with the guide plate 20. Therefore, when the emergency stop button 30 is pressed, causing the guide plate 20 to slide, the hinged position of the reset member 60 and the guide plate 20 will also slide, thereby compressing the elastic member 70 and storing elastic potential energy. After the emergency is released, the elastic member 70 can release the elastic potential energy, causing the guide plate 20 to slide and re-engage the normally closed component 10, disconnecting the normally open component 40.

[0092] Taking the relay 100 as shown in Figure 5 as an example, the first direction X is the left-right direction in the figure, and the second direction Y is the up-down direction in the figure. When the emergency stop button 30 is pressed, the emergency stop button 30 can push the guide plate 20 to slide to the right. At this time, the elastic element 70 can store elastic potential energy. After the emergency is released, the elastic element 70 can extend under its own elastic force and drive the guide plate 20 to slide to the left.

[0093] It should be noted that, in this embodiment, the relay 100 may have an automatic reset function. For example, in an emergency, the user can press down on the emergency stop button 30, causing the emergency stop button 30 to drive the guide plate 20 to slide to the right. After the emergency is resolved, the user can operate the emergency stop button 30 again, causing the emergency stop button 30 to slide upward to the unpressed position. At this time, the elastic element 70 can automatically extend to drive the guide plate 20 to slide to the left.

[0094] Alternatively, a reset button can be provided in relay 100. After pressing the emergency stop button 30 in an emergency to switch the states of normally closed component 10 and normally open component 40, the reset element 60 can be held in its current position. At this time, even if the emergency stop button 30 is operated to slide it upwards, the reset element 60 and the base 50 still exert a compressive force on the elastic element 70, keeping the elastic element 70 in a compressed state. After the emergency is resolved, the user can operate the reset button to remove the restriction on the reset element 60, after which the elastic element 70 can extend, driving the guide plate 20 to slide to the left.

[0095] It should also be noted that, in the embodiments of this application, the elastic element 70 can be a tension spring, a spring or other structure made of elastic material, and this application does not specifically limit it.

[0096] In some embodiments, such as Figure 2 and Figure 7 As shown, the emergency stop button 30 may include a button 31 and a push block 32. The push block 32 is connected to one side of the button 31 in the first direction X, and a push surface 301 is disposed on the push block 32. In this way, the button 31 can apply force to the guide plate 20 through the push block 32, so that the guide plate 20 can slide along the first direction X.

[0097] It should be noted that button 31 is used to receive pressing operations, and the emergency stop button 30 can be slidably mounted on the base 50 via button 31. In order to facilitate button 31 receiving pressing operations, or in other words, to facilitate user operation, button 31 can have at least a portion extending out of the base 50. The portion extending out of the base 50 can form the operating end 302, which can facilitate the emergency stop button 30 receiving pressing operations.

[0098] In this embodiment, the push block 32 can be configured in different ways. For example, the button 31 and the push block 32 can be integrally formed, so that the button 31 and the push block 32 can be manufactured simultaneously in one production run. This makes the manufacture of the emergency stop button 30 simpler and more convenient. On the other hand, it also makes the connection strength between the push block 32 and the button 31 higher, which can reduce the possibility of the push block 32 falling off after long-term use of the emergency stop button 30.

[0099] Of course, the push block 32 can be connected to the button 31 by means of adhesive, snap-fit, etc. This application embodiment does not make specific limitations on this.

[0100] It is understood that in this embodiment, the relay 100 can be a thermal relay, in which case a bimetallic strip is also provided. Under normal operating conditions, the normally closed stationary contact 12 is connected to the normally closed moving contact, and the normally open stationary contact 42 is connected to the normally open moving contact 41. In case of overload, the bimetallic strip deforms and drives the normally closed and normally open supports to disconnect the normally closed assembly 10 and connect the normally open assembly 40. When the emergency stop button 30 receives a press operation, the emergency stop button 30 directly drives the normally closed moving contact 11 and the normally open moving contact 41 to operate via the guide plate 20.

[0101] The specific arrangement and coordination of the bimetallic strip, normally open moving contact 41, and normally closed moving contact 11 can be found in the thermal relay settings and operating principles in related technologies, and will not be repeated here in the embodiments of this application.

[0102] Of course, relay 100 can also be other types of relays, such as current relays, etc. The specific type of relay 100 is not specifically limited in the embodiments of this application.

[0103] In summary, in this embodiment, when there is an emergency requiring the circuit containing relay 100 to be disconnected, the emergency stop button 30 can be pressed, allowing the emergency stop button 30 to control the normally closed component 10 to open via the guide plate 20. Since the guide plate 20 is slidably disposed along the second direction Y, the force received by the normally closed component 10 only slides along the second direction Y. Thus, the control of the normally closed component 10 in this application is more reliable and precise, thereby reducing the possibility of relay 100 emergency stop failure leading to damage to relay 100 or even other components in the circuit containing relay 100.

[0104] Finally, it should be noted that the above embodiments are merely specific implementations of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be covered 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.
