Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric control devices, in particular to a relay. BACKGROUND

[0002] A relay is an electronic control device, which has a control system (also known as an input circuit) and a controlled system (also known as an output circuit), and is usually applied in an automatic control circuit. The relay is actually a kind of "automatic switch" that uses a small current to control a large current. Therefore, it plays a role of automatic regulation, safety protection, and conversion of circuits in the circuit.

[0003] As one of the relays, a magnetic latching relay includes two contact parts and a driving part. One of the contact parts has a moving contact, and the other contact part has a stationary contact. The driving part has a push rod, and the driving part can drive one of the contact parts to reciprocate through the push rod, so as to make the moving contact contact or separate from the stationary contact.

[0004] When the moving contact and the stationary contact are disconnected, an arc is easily generated between the two contacts. After the arc is lengthened, the push rod is easily ablated, which causes the end of the push rod to be deformed or damaged, affects the precision of the movement of the push rod, and even causes the relay to be unable to switch between the closed state and the disconnected state, and seriously shortens the service life of the relay. CONTENT OF THE INVENTION

[0005] Embodiments of the present application provide a relay to solve the problem of arc ablation of the push rod in the related art.

[0006] The relay of the embodiments of the present application includes:

[0007] The first contact part includes a first moving contact and a first moving spring plate on which the first moving contact is arranged.

[0008] The second contact part includes a first stationary contact.

[0009] The driving part has a first driving member configured to drive the first moving spring plate to move, so as to make the first moving contact contact or separate from the first stationary contact. The first moving contact and the first stationary contact form a contact group.

[0010] The isolating member is arranged between the contact group and the first driving member.

[0011] According to some embodiments of the present application, the isolating member is made of a ceramic material.

[0012] According to some embodiments of the present application, the isolating member is arranged on the first moving spring plate.

[0013] According to some embodiments of the present application, the isolation member is in an integral structure with the first moving contact.

[0014] According to some embodiments of the present application, the first driving member is located around the first moving contact and the first stationary contact.

[0015] According to some embodiments of the present application, the isolation member is disposed on a side surface of the first driving member facing the first moving contact and the first stationary contact.

[0016] According to some embodiments of the present application, the isolation member is in a separate structure with the first driving member.

[0017] According to some embodiments of the present application, the isolation member is formed by bending an end portion of the first moving contact towards a side facing the first stationary contact.

[0018] According to some embodiments of the present application, the first moving contact comprises a plurality of stacked leaf springs, and an end portion of any one of the leaf springs is bent towards a side facing the first stationary contact to form the isolation member.

[0019] According to some embodiments of the present application, the isolation member is formed on the leaf spring closest to the first stationary contact.

[0020] According to some embodiments of the present application, the first driving member is located on a side of the first moving contact facing away from the first stationary contact.

[0021] A portion of the first moving contact is the isolation member.

[0022] According to some embodiments of the present application, the relay further comprises a permanent magnet disposed around the first moving contact and the first stationary contact for eliminating an arc generated between the first moving contact and the first stationary contact.

[0023] According to some embodiments of the present application, the relay further comprises a housing, and the first contact portion, the second contact portion and the driving portion are located in the housing.

[0024] The isolation member is located in the housing and connected with the housing.

[0025] According to some embodiments of the present application, the driving portion further comprises an armature assembly, and the armature assembly is in an integral structure with the first driving member.

[0026] According to some embodiments of this application, the relay further includes a housing, the armature assembly includes a swinging part and an armature body, the swinging part is swingable relative to the housing and is integrally injection molded to the armature body, and the first driving member is integrally connected to the swinging part for driving the first moving spring to move.

[0027] An embodiment of the above application has at least the following advantages or beneficial effects:

[0028] In the relay of this application embodiment, since the isolator is disposed between the contact group and the first driving member, it can prevent the electric arc generated between the first moving contact and the first stationary contact from extending to the first driving member, thereby avoiding the electric arc from burning the first driving member. This not only ensures the accuracy of the movement of the first driving member, but also extends the service life of the relay.

[0029] Furthermore, since the first driving element is located on the side of the first moving spring facing away from the first stationary contact, and not around the first moving contact and the first stationary contact, the position of the permanent magnet can be closer to the first moving contact and the first stationary contact, thereby increasing the magnetic field strength at the center of the contact and improving the arc extinguishing effect.

Like reference numerals refer to like elements throughout the figures, and thus description of the same will be simplified or omitted.

[0046] It is to be understood that the terms "including", "comprising", "having" and variations thereof herein are intended to cover the case where non-excluded items are included, as well as the case where excluded items are not included. For example, a process, method, system, product, or apparatus that comprises a list of steps or units are not necessarily limited to the listed steps or units but can include other steps or units not expressly listed or can include other steps or units inherent to such process, method, product, or apparatus.

[0047] The example embodiments provide a relay, which can be a latching relay, but is not limited thereto.

[0048] As Figure 1 and Figure 2As shown, the relay of the embodiment of the present application comprises a housing 100, a first contact portion 200, a second contact portion 300 and a driving portion 400. The first contact portion 200, the second contact portion 300 and the driving portion 400 are arranged in the housing 100. The first contact portion 200 and the second contact portion 300 have a closed state and an open state, and the driving portion 400 is configured to drive the first contact portion 200 and the second contact portion 300 to switch from the closed state to the open state and from the open state to the closed state.

[0049] In an embodiment, as shown, Figure 2 The housing 100 can comprise a first shell 110 and a second shell 120, which are connected together and form a hollow chamber for accommodating the first contact portion 200, the second contact portion 300 and the driving portion 400. The shape of the first shell 110 and the second shell 120 after being connected can have various embodiments, for example, in the embodiment of the present application, the shape of the first shell 110 and the second shell 120 after being connected is a hollow cuboid. Of course, in other embodiments, the shape of the first shell 110 and the second shell 120 after being connected can also be a hollow cylinder or other suitable shape.

[0050] As an example, the second shell 120 is a cuboid shape with an opening, and the first contact portion 200, the second contact portion 300 and the driving portion 400 are arranged in the second shell 120 through the opening of the second shell 120. The first shell 110 is plate-shaped, and the first shell 110 is buckled on the opening of the second shell 120 to form a hollow cuboid.

[0051] Of course, in other embodiments, the first shell 110 and the second shell 120 are both cuboid-shaped and have an opening on one face, the opening of the first shell 110 is arranged opposite to the opening of the second shell 120, and the first shell 110 and the second shell 120 are buckled to form a hollow chamber for accommodating the first contact portion 200, the second contact portion 300 and the driving portion 400.

[0052] As shown, Figure 3 The driving portion 400 comprises a coil assembly 440, an armature assembly 420, a first driving member 410 and a second driving member 450. The coil assembly 440 is arranged in the second shell 120, the armature assembly 420 is swingably arranged in the second shell 120 relative to the second shell 120, and the first driving member 410 and the second driving member 450 are both connected to the armature assembly 420. The coil assembly 440 is electromagnetically coupled with the armature assembly 420 and is configured to drive the armature assembly 420 to swing in response to an input signal, and in turn the armature assembly 420 drives the first driving member 410 and the second driving member 450 to move.

[0053] In an embodiment, the housing 100 further comprises a fixing member 130, which can be fixedly installed on the second housing 120. The armature assembly 420 is swingably connected to the fixing member 130.

[0054] The armature assembly 420 can comprise a swing portion 420a and two oppositely arranged armature bodies 420b. The swing portion 420a is swingably connected to the fixing member 130, and the armature bodies 420b are connected to the swing portion 420a. In an embodiment, the swing portion 420a is made of plastic and is integrally connected to the armature bodies 420b by one-piece injection molding.

[0055] As shown in FIG. 1, the first contact portion 200 comprises a first moving spring plate 210, a first moving contact 220, a second stationary contact 250, and a first lead-out plate 260. The first moving contact 220 and the second stationary contact 250 are both arranged on the first moving spring plate 210 and are spaced apart along the length direction of the first moving spring plate 210. The first lead-out plate 260 is connected to the second stationary contact 250. Figure 3

[0056] In an embodiment, the first moving contact 220 can be connected to the first moving spring plate 210 by riveting, and the second stationary contact 250 can connect the first moving spring plate 210 and the first lead-out plate 260 by riveting.

[0057] Of course, in other embodiments, the first moving contact 220 and the second stationary contact 250 can also be integrally formed on the first moving spring plate 210.

[0058] The second contact portion 300 comprises a second moving spring plate 310, a first stationary contact 320, a second moving contact 330, and a second lead-out plate 360. The first stationary contact 320 and the second moving contact 330 are both arranged on the second moving spring plate 310 and are spaced apart along the length direction of the second moving spring plate 310. The second lead-out plate 360 is connected to the first stationary contact 320.

[0059] In an embodiment, the first stationary contact 320 can connect the second moving spring plate 310 and the second lead-out plate 360 by riveting, and the second moving contact 330 can be connected to the second moving spring plate 310 by riveting.

[0060] Of course, in other embodiments, the first stationary contact 320 and the second moving contact 330 can also be integrally formed on the second moving spring plate 310.

[0061] As shown in FIG. 1, the first contact portion 200 comprises a first moving spring plate 210, a first moving contact 220, a second stationary contact 250, and a first lead-out plate 260. The first moving contact 220 and the second stationary contact 250 are both arranged on the first moving spring plate 210 and are spaced apart along the length direction of the first moving spring plate 210. The first lead-out plate 260 is connected to the second stationary contact 250. Figure 3 ​As shown, the first moving spring 210 and the second moving spring 310 are arranged side by side along the thickness direction of the moving spring. In the thickness direction of the moving spring, the position of the first moving contact 220 corresponds to the position of the first stationary contact 320, and the first moving contact 220 is used to contact or separate from the first stationary contact 320; the position of the second moving contact 330 corresponds to the position of the second stationary contact 250, and the second moving contact 330 is used to contact or separate from the second stationary contact 250.

[0062] The first driving member 410 is used to drive the first moving spring 210 to move so that the first moving contact 220 contacts or separates from the first stationary contact 320; the second driving member 450 is used to drive the second moving spring 310 to move so that the second moving contact 330 contacts or separates from the second stationary contact 250.

[0063] When the first contact portion 200 and the second contact portion 300 are in the closed state, the first moving contact 220 is in contact with the first stationary contact 320, and the second moving contact 330 is in contact with the second stationary contact 250, so that the first moving spring 210 and the second moving spring 310 form a parallel circuit structure. When the first contact portion 200 and the second contact portion 300 are in the open state, the first moving contact 220 is separated from the first stationary contact 320, and the second moving contact 330 is separated from the second stationary contact 250.

[0064] A portion of the first lead 260 extends out of the outer surface of the housing 100, and a portion of the second lead 360 extends out of the surface of the housing 100. The portions of the first lead 260 and the second lead 360 extending out of the outer surface of the housing 100 are respectively used for electrical connection with the positive and negative terminals of the load.

[0065] Of course, the first contact portion 200 and the second contact portion 300 are not limited to a parallel circuit structure when closed. For example, in another embodiment, the first contact portion 200 includes a first moving spring 210 and a first moving contact 220, with the first moving contact 220 disposed on the first moving spring 210. The second contact portion 300 includes a second lead-out piece 360 ​​and a first stationary contact 320, with the first stationary contact 320 disposed on the second lead-out piece 360. The driving portion 400 has a first driving member 410, which drives the first moving spring 210 to move, so that the first moving contact 220 contacts or separates from the first stationary contact 320.

[0066] like Figure 3 As shown, both the first drive member 410 and the second drive member 450 are integrally formed with the armature assembly 420. For example, both the first drive member 410 and the second drive member 450 are integrally formed with the swing portion 420a of the armature assembly 420.

[0067] In one embodiment, the first drive member 410 and the second drive member 450 are made of plastic and are connected to the armature assembly 420 by integral injection molding.

[0068] Compared to the existing technology where the push rod and armature assembly 420 are separate structures and connected by a transmission link, the first driving component 410 and the armature assembly 420 in this embodiment are an integral structure. Firstly, this reduces the number of parts in the driving part 400 and lowers mold costs. Secondly, it reduces the assembly steps of the push rod and armature assembly 420 and lowers assembly difficulty. Thirdly, it reduces transmission errors caused by factors such as dimensional tolerances, deformation, and assembly precision of the push rod. Fourthly, it avoids contact point bounce and spring impact caused by the inertia of the push rod. Fifthly, the integral structure of the first driving component 410 and the armature assembly 420 makes the structure of the driving part 400 more compact and reduces the internal volume occupied by the outer casing 100.

[0069] like Figure 3 As shown, the drive part 400 also includes a push rod 430. One end of the push rod 430 is connected to the second drive member 450, and the other end of the push rod 430 is connected to the second movable spring 310. The second drive member 450 drives the second movable spring 310 to move through the push rod 430.

[0070] Of course, in other embodiments, the second drive member 450 may be connected directly to the second moving spring 310 instead of through the push rod 430.

[0071] In one embodiment, the first driving member 410 may not be an integral part of the armature assembly 420, but rather a separate structure from it. The armature assembly 420 drives the first movable spring 210 to move via the first driving member 410.

[0072] like Figure 3 As shown, the first moving contact 220 and the first stationary contact 320 form a contact group 370. The relay in this embodiment of the application also includes an isolator 600, which is disposed between the contact group 370 and the first driving member 410, and is used to separate the contact group 370 from the first driving member 410.

[0073] In the relay of this application embodiment, since the isolator 600 is disposed between the contact group 370 and the first driving member 410, it can prevent the electric arc generated between the first moving contact 220 and the first stationary contact 320 from extending to the first driving member 410, thereby avoiding the electric arc from burning the first driving member 410, which not only ensures the accuracy of the movement of the first driving member 410, but also extends the service life of the relay.

[0074] like Figure 3The first driving member 410 is located on the side of the first moving contact 210 away from the first stationary contact 320. A portion of the first moving contact 210 is the isolation member 600.

[0075] In the embodiment of the present application, the first driving member 410 is located on the side of the first moving contact 210 away from the first stationary contact 320, and does not extend into the periphery of the first moving contact 220 and the first stationary contact 320 beyond the first moving contact 210. Therefore, a portion of the first moving contact 210 can function as an isolation member 600 to isolate the first driving member 410 from the contact group 370, preventing the first moving contact 220 and the first stationary contact 320 from being ablated by the arc generated therebetween.

[0076] As shown in FIG. 1, the relay further includes a permanent magnet 500 disposed in the periphery of the first moving contact 220 and the first stationary contact 320 for extinguishing the arc generated between the first moving contact 220 and the first stationary contact 320. Figure 4 to Figure 6

[0077] In the embodiment of the present application, the first driving member 410 is located on the side of the first moving contact 210 away from the first stationary contact 320, and does not extend into the periphery of the first moving contact 220 and the first stationary contact 320. Therefore, the permanent magnet 500 can be located closer to the first moving contact 220 and the first stationary contact 320, thereby increasing the magnetic field strength in the center of the contacts and improving the arc extinguishing effect.

[0078] As shown in FIG. 2, the relay of the second embodiment of the present application is similar to the relay of the first embodiment of the present application, and the differences between them are as follows: Figure 4 to Figure 6 The first driving member 410 is located in the periphery of the first moving contact 220 and the first stationary contact 320. Moreover, the armature assembly 420 and the first driving member 410 are in a split structure.

[0079] The isolation member 600 is located in the periphery of the first moving contact 220 and the first stationary contact 320, and is disposed on the first moving contact 210. In an embodiment, the isolation member 600 and the first moving contact 210 are in an integral structure. Of course, in other embodiments, the isolation member 600 and the first moving contact 210 can also be in a split structure.

[0080] As shown in FIG. 3, the isolation member 600 is formed by bending the end of the first moving contact 210 toward the side facing the first stationary contact 320.

[0081] Figure 7 In an embodiment, the first moving contact 210 includes a plurality of stacked leaf springs 211, and the end of any one of the leaf springs 211 is bent toward the side facing the first stationary contact 320 to form the isolation member 600.

[0082] In an embodiment, the first moving contact 210 includes a plurality of stacked leaf springs 211, and the end of any one of the leaf springs 211 is bent toward the side facing the first stationary contact 320 to form the isolation member 600.

[0083] ​​It can be understood that the number of the leaf springs 211 can be two, three, four or other numbers, and the application does not particularly limit this.

[0084] Further, the isolation piece 600 is formed on the leaf spring 211 closest to the first stationary contact 320. Of course, in other embodiments, the isolation piece 600 can also be formed on other leaf springs 211.

[0085] Of course, the isolation piece 600 and the first moving spring 210 can also be a split structure. For example, the isolation piece 600 and the first moving spring 210 are connected by riveting, gluing, welding or the like, and the application does not particularly limit this.

[0086] When the isolation piece 600 and the first moving spring 210 are a split structure, the isolation piece 600 can be made of a ceramic material. On the one hand, the ceramic material has a better cooling effect, which can cool the arc generated between the first moving contact 220 and the first stationary contact 320; on the other hand, the ceramic material has a good heat insulation effect, thereby improving the isolation effect of the isolation piece 600 in isolating the arc.

[0087] As shown in FIG. 6, the relay of the third embodiment of the application is the same as the relay of the second embodiment, and the difference is that: ​ The isolation piece 600 and the first driving piece 410 are a split structure, and the isolation piece 600 is arranged on the side surface of the first driving piece 410 facing the first moving contact 220 and the first stationary contact 320.

[0088] The isolation piece 600 can be connected to the first driving piece 410 by gluing, riveting, welding or the like.

[0089] In an embodiment, the isolation piece 600 can be made of a metal material, a ceramic material or other materials capable of isolating the arc.

[0090] Of course, it can be understood that the isolation piece 600 can also not be connected to the first driving piece 410. For example, in other embodiments, the isolation piece 600 can also be connected to the housing 100. Further, the isolation piece 600 is connected to the first housing 110, or the isolation piece 600 is connected to the second housing 120.

[0091] In summary, the relay of the embodiments of the application has at least the following advantages and beneficial effects:

[0092]

[0093] ​The relay of the embodiment of the application can block the arc generated between the first moving contact 220 and the first stationary contact 320 from extending to the first driving member 410, thereby avoiding the arc ablation of the first driving member 410, ensuring the movement precision of the first driving member 410, and prolonging the service life of the relay.

[0094] Further, since the first driving member 410 is located on the side of the first moving spring plate 210 away from the first stationary contact 320, and not around the first moving contact 220 and the first stationary contact 320, the position of the permanent magnet 500 can be closer to the first moving contact 220 and the first stationary contact 320, thereby increasing the magnetic field strength of the contact center and improving the arc extinguishing effect.
