Description

Technical Field

[0001] This application relates to the field of electrical control device technology, and more specifically, to a push rod component and a relay. Background Technology

[0002] A relay is an electronic control device that has a control system (also known as an input circuit) and a controlled system (also known as an output circuit), and is commonly used in automatic control circuits. Essentially, a relay is an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays a role in automatic adjustment, safety protection, and circuit switching in circuits.

[0003] The relay includes a stationary contact assembly, a moving contact assembly, and a push rod assembly. The moving contact assembly is mounted on the push rod assembly, which drives the moving contact assembly to make contact or separate from the stationary contact assembly. The push rod assembly includes an insulating component, a push rod, and multiple contact supports. The insulating component is integrally connected to the push rod and the multiple contact supports, which are arranged side by side.

[0004] In related technologies, insulating components are typically made of plastic. When multiple contact supports are arranged side-by-side, the insulating component is quite long. This makes the portion of the insulating component located between two adjacent contact supports prone to deformation during injection molding, affecting the consistency of the positions of the multiple contact supports and consequently the travel of the moving contact assembly and the contact position between the moving and stationary contact assemblies. Furthermore, during the reciprocating motion of the push rod component, the portion of the insulating component located between two adjacent contact supports may experience fatigue fracture due to insufficient structural strength. Utility Model Content

[0008] Multiple contact supports;

[0009] At least one reinforcing insert, wherein one reinforcing insert is connected between two adjacent contact supports; and

[0010] An insulating element is connected to the push rod, the contact bracket, and the reinforcing insert.

[0011] According to some embodiments of this application, the reinforcing insert includes two reinforcing members, which are respectively connected to two adjacent contact supports.

[0012] According to some embodiments of this application, the two reinforcing members of the reinforcing insert are joined together, and two joint seams are formed at the joint position, the two joint seams being non-collinear.

[0014] The plurality of contact supports are arranged side by side in a first direction, and the axial direction of the push rod is a second direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0015] According to some embodiments of this application, a plurality of the contact supports are arranged side by side, and two of the reinforcing members of the reinforcing insert extend from two adjacent contact supports, along the arrangement direction of the plurality of contact supports, and toward each other.

[0016] According to some embodiments of this application, the two reinforcing members of the reinforcing insert form a through hole, and the push rod passes through the through hole.

[0017] According to some embodiments of this application, the reinforcing member and the corresponding contact bracket are an integral structure.

[0018] According to some embodiments of this application, the reinforcing member is formed by bending a portion of the contact support.

[0019] According to some embodiments of this application, the insulating element is integrally connected to the push rod, the contact bracket, and the reinforcing insert by injection molding.

[0020] According to some embodiments of this application, a plurality of contact supports are arranged side by side, each contact support including a connecting portion and two side portions, one end of each of the two side portions being respectively connected to both ends of the connecting portion along a first direction, the first direction being the arrangement direction of the plurality of contact supports;

[0021] The reinforcing insert is connected between the connecting portions of two adjacent contact supports, or the reinforcing insert is connected between two adjacent side portions of two adjacent contact supports.

[0022] According to some embodiments of this application, the connecting portion is flat and multiple connecting portions are located on the same plane.

[0023] According to some embodiments of this application, the insulating element covers one end of the push rod, the connecting portion, and the reinforcing insert.

[0024] According to some embodiments of this application, the reinforcing insert is a metal part.

[0025] According to some embodiments of this application, the reinforcing insert has a through hole, and the push rod passes through the through hole.

[0026] According to some embodiments of this application, the reinforcing insert is a single integral piece, and is separately connected between two adjacent contact supports.

[0027] The relay in this application embodiment includes the push rod component described in any of the above claims.

[0028] According to some embodiments of this application, the relay further includes:

[0029] First static contact assembly and second static contact assembly;

[0030] A movable component is movable relative to the first static contact component and the second static contact component. The movable component includes a first movable component and a second movable component. The first movable component is used to contact or separate from the first static contact component, and the second movable component is used to contact or separate from the second static contact component. The second movable component includes the push rod member.

[0031] The moving component is configured to switch the relay between a first state and a second state in response to an input signal; when the relay is in the first state, the first moving component is in contact with the first stationary contact component, while the second moving component is separated from the second stationary contact component; when the relay is in the second state, the second moving component is in contact with both the first stationary contact component and the second stationary contact component, while the first moving component is separated from the first stationary contact component.

[0032] According to some embodiments of this application, the first state is that the external circuit controlled by the relay is in a series connection state, and the second state is that the external circuit controlled by the relay is in a parallel connection state.

[0033] According to some embodiments of this application, the first moving component includes a first push rod member and a first moving contact component. The first moving contact component is mounted on the first push rod member and is used to contact or separate from the first static contact component.

[0034] The push rod component of the second moving assembly is defined as the second push rod component. The second moving assembly also includes two second moving contact components. The two second moving contact components are respectively installed in the two contact brackets of the second push rod component. The second moving contact components are used to contact or separate from the first static contact component and the second static contact component.

[0035] According to some embodiments of this application, the first static contact assembly includes two first static contacts, and the second static contact assembly includes two second static contacts.

[0036] When the relay is in the first state, the first moving contact component is in contact with both of the first stationary contacts simultaneously, and the second moving contact component is separated from the second stationary contacts.

[0037] When the relay is in the second state, one end of each of the two second moving contact components is in contact with the two first stationary contacts, and the other end is in contact with the two second stationary contacts, and the first moving contact component is separated from the first stationary contact.

[0038] An embodiment of the above application has at least the following advantages or beneficial effects:

[0039] In the push rod component of this application embodiment, a reinforcing insert connects two adjacent contact supports among multiple contact supports. Thus, when the insulating component connects the push rod and the multiple contact supports, the portion of the insulating component located between two adjacent contact supports has a reinforcing insert. This reinforcing insert improves the structural strength of the central region of the insulating component. On one hand, the reinforcing insert reduces the risk of deformation of the insulating component during molding, ensuring the consistency of the positions of the multiple contact supports and guaranteeing the contact position of the moving and stationary contacts. On the other hand, the reinforcing insert improves the strength of the central region of the insulating component, preventing breakage of the push rod component during reciprocating motion.

[0040] Furthermore, the reinforcing member and the corresponding contact support are an integral structure. From the perspective of the number of parts, the push rod component in this embodiment does not increase the number of parts, thus facilitating transportation and not affecting assembly efficiency. From the perspective of processing difficulty, the integral structure of the reinforcing member and the corresponding contact support reduces processing difficulty. In addition, the two non-collinear butt joints formed by the two reinforcing members at the mating position can also prevent the insulation component from breaking as a whole.

[0041] Furthermore, the push rod passes through the perforation formed by the two reinforcing members, meaning that part of the push rod is located between two adjacent contact supports. Thus, the portion of the insulation component located between the two contact supports not only covers the reinforcing insert but also the push rod portion, further improving the structural strength of this part of the insulation component. In addition, when the push rod, contact supports, reinforcing insert, and insulation component are connected by injection molding, the perforation can, to some extent, limit the movement of the push rod, preventing significant displacement of the push rod relative to the contact supports during the molding process.

[0042] Furthermore, the two joint seams formed at the points where the two reinforcing members meet are not collinear. This ensures that even if a crack occurs in the part of the insulation component located between two adjacent contact supports, the crack will not spread along a straight line, thus preventing the insulation component from breaking as a whole.

[0055] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this application will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0056] It is understood that the terms "comprising" and "having," and any variations thereof, in the embodiments of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to these processes, methods, products, or devices.

[0057] like Figures 1 to 4 As shown, the relay of this embodiment includes a housing 10, a contact cavity 20, a stationary contact assembly 30, a moving assembly 40, and a magnetic circuit portion 60. The contact cavity 20, the stationary contact assembly 30, the moving assembly 40, and the magnetic circuit portion 60 are disposed within the housing 10. The stationary contact assembly 30 is mounted on the contact cavity 20, and a portion of the moving assembly 40 is located within the contact chamber 23 enclosed by the contact cavity 20 and is movable relative to the contact cavity 20. The magnetic circuit portion 60 is configured to drive the moving assembly 40 to move in response to an input signal, so that the moving assembly 40 contacts or separates from the stationary contact assembly 30, thereby switching the relay between a first state and a second state.

[0058] In one embodiment, in the first state and the second state, one is an external circuit controlled by a relay in parallel, and the other is an external circuit controlled by a relay in series.

[0059] Of course, in other embodiments, one of the first state and the second state can be that the relay is in a closed state and the other is that the relay is in an open state.

[0060] The following explanation will be based on the example where the external circuit controlled by the relay is in series in the first state and in parallel in the second state.

[0061] As an example, the outer casing 10 may include a first casing 11 and a second casing 12, which are connected to form a cavity for accommodating the contact cavity 20, the static contact assembly 30, the moving assembly 40, and the magnetic circuit portion 60. The shape of the first casing 11 and the second casing 12 connected together can be a cuboid, a cylinder, etc. In the embodiments of this application, the first casing 11 and the second casing 12 are connected to form a hollow cuboid, but this is not a limitation.

[0062] In one embodiment, both the first shell 11 and the second shell 12 are cuboid in shape and each has an opening on one side. The opening of the first shell 11 is opposite to the opening of the second shell 12, and the first shell 11 and the second shell 12 are fastened together to form a cavity for accommodating the cavity.

[0063] Of course, in other embodiments, the first shell 11 can be a flat plate structure, and the second shell 12 can be a cuboid shape with an opening, forming a cavity after the first shell 11 and the second shell 12 are fastened together.

[0064] like Figure 2 and Figure 4 As shown, the contact cavity 20 includes an insulating cover 21 and a yoke plate 22. The insulating cover 21 covers one side surface of the yoke plate 22 in the thickness direction, and the insulating cover 21 and the yoke plate 22 form a contact cavity 23. The magnetic circuit portion 60 is located on the side of the yoke plate 22 facing away from the insulating cover 21.

[0065] In one embodiment, the insulating cover 21 may include a ceramic cover 211 and a frame plate 212. The ceramic cover 211 is made of ceramic material and is connected to the yoke plate 22 via the frame plate 212. The frame plate 212 may be a ring-shaped metal component, for example, made of an iron-nickel alloy. One end of the frame plate 212 is connected to the opening edge of the ceramic cover 211, for example, by laser welding, brazing, resistance welding, or adhesive bonding. The other end of the frame plate 212 is connected to the yoke plate 22, for example, by laser welding, brazing, resistance welding, or adhesive bonding.

[0066] like Figure 2 and Figure 4 As shown, the static contact assembly 30 includes a first static contact assembly 31 and a second static contact assembly 32, both of which are mounted on the ceramic cover 211.

[0067] In one embodiment, the first static contact assembly 31 has two first static contacts 311, and the second static contact assembly 32 has two second static contacts 321. Both the first static contacts 311 and the second static contacts 321 are mounted on a ceramic cover 211. The two first static contacts 311 are arranged at a distance along a first direction D1, and the two second static contacts 321 are also arranged at a distance along the first direction D1. The positions of the two first static contacts 311 correspond to the positions of the two second static contacts 321 along a third direction D3.

[0068] Among them, the direction of motion of the moving component 40 is the second direction D2, and the first direction D1, the second direction D2, and the third direction D3 are perpendicular to each other.

[0069] The yoke plate 22 has a first through hole 221 and a second through hole 222. The first through hole 221 and the second through hole 222 penetrate the yoke plate 22 along the second direction D2, and both the first through hole 221 and the second through hole 222 communicate with the contact chamber 23. The moving assembly 40 includes a first moving assembly 40a and a second moving assembly 40b. The first moving assembly 40a is movably disposed in the first through hole 221, and the second moving assembly 40b is movably disposed in the second through hole 222.

[0070] like Figure 4 As shown, the first moving component 40a includes a first push rod component 40c and a first moving contact component 415. The first push rod component 40c is movably disposed within the first through hole 221, and the first moving contact component 415 is mounted on the first push rod component 40c. The first moving contact component 415 is used to contact or separate from the first stationary contact component 31.

[0071] The second moving component 40b includes a second push rod component 40d and two second moving contact components 425. The second push rod component 40d is movably inserted into the second through hole 222, and the second moving contact components 425 are mounted on the second push rod component 40d. The second moving contact components 425 are used to simultaneously contact or separate from the first static contact component 31 and the second static contact component 32.

[0072] The magnetic circuit portion 60 includes a first magnetic circuit portion 61 and a second magnetic circuit portion 62. The first magnetic circuit portion 61 is located on the side of the yoke plate 22 facing away from the insulating cover 21 and is connected to the first push rod member 40c. The first magnetic circuit portion 61 is configured to drive the first push rod member 40c to move in response to a first input signal, such that the first push rod member 40c drives the first moving contact assembly 415 to contact or separate from the first stationary contact assembly 31. The second magnetic circuit portion 62 is located on the side of the yoke plate 22 facing away from the insulating cover 21 and is connected to the second push rod member 40d. The second magnetic circuit portion 62 is configured to drive the second push rod member 40d to move in response to a second input signal, such that the second push rod member 40d drives the second moving contact assembly 425 to simultaneously contact or separate from the first stationary contact assembly 31 and the second stationary contact assembly 32.

[0073] The first magnetic circuit portion 61 can be a magnetic holding structure or a non-magnetic holding structure, and the second magnetic circuit portion 62 can be a magnetic holding structure or a non-magnetic holding structure.

[0074] When the external circuit controlled by the relay is in series, the first moving contact component 415 is in contact with the first stationary contact component 31, while the second moving contact component 425 is separated from the second stationary contact component 32. When the external circuit controlled by the relay is in parallel, the second moving contact component 425 is in contact with both the first stationary contact component 31 and the second stationary contact component 32, while the first moving contact component 415 is separated from the first stationary contact component 31.

[0075] As an example, such as Figure 4 As shown, the first moving contact assembly 415 may include one or more first moving contact elements 4151. When the first moving contact assembly 415 includes multiple first moving contact elements 4151, the multiple first moving contact elements 4151 may be arranged side by side along the third direction D3.

[0076] like Figure 6 As shown, the second movable contact assembly 425 may include one or more second movable contact elements 4251. When the second movable contact assembly 425 includes multiple second movable contact elements 4251, the multiple second movable contact elements 4251 may be arranged side by side along the first direction D1.

[0077] like Figures 6 to 9 As shown, the second push rod component 40d includes a push rod 421, a plurality of contact supports 423 arranged side by side, at least one reinforcing insert 426, and an insulating member 422. A reinforcing insert 426 is connected between two adjacent contact supports 423; the insulating member 422 is connected to the push rod 421, the contact supports 423, and the reinforcing insert 426, so that the push rod 421, the plurality of contact supports 423, the at least one reinforcing insert 426, and the insulating member 422 constitute a single integral component.

[0078] The axial direction of the push rod 421 is the second direction D2, and the arrangement direction of the multiple contact supports 423 is the first direction D1.

[0079] When there are two contact supports 423, the two second moving contact assemblies 425 are located in the two contact supports 423 respectively.

[0080] In this embodiment of the push rod component, a reinforcing insert 426 connects adjacent contact supports 423 among a plurality of side-by-side arranged contact supports 423. Thus, when the insulating member 422 connects the push rod 421 and the plurality of contact supports 423, the portion of the insulating member 422 located between adjacent contact supports 423 is provided with the reinforcing insert 426. The reinforcing insert 426 can improve the structural strength of the central region of the insulating member 422. On the one hand, the reinforcing insert 426 can reduce the risk of deformation of the insulating member 422 during molding, ensuring the consistency of the positions of the plurality of contact supports 423 and ensuring the contact position of the moving and stationary contacts; on the other hand, the reinforcing insert 426 can improve the strength of the central region of the insulating member 422, avoiding the problem of breakage of the push rod component during reciprocating motion.

[0081] In one embodiment, the reinforcing insert 426 includes two reinforcing members 4261, which are respectively connected to two adjacent contact supports 423. The reinforcing members 4261 and the corresponding contact supports 423 are integrally formed.

[0082] In this embodiment, the reinforcing member 4261 and the corresponding contact bracket 423 are an integral structure. From the perspective of the number of parts, the push rod component in this embodiment does not increase the number of parts, thus facilitating transportation and not affecting assembly efficiency. From the perspective of processing difficulty, the integral structure of the reinforcing member 4261 and the corresponding contact bracket 423 reduces processing difficulty. Furthermore, the two non-collinear butt joints 4262 formed at the mating position of the two reinforcing members 4261 can also prevent the insulating member 422 from breaking as a whole.

[0083] In one embodiment, the two reinforcing members 4261 of the reinforcing insert 426 extend from two adjacent contact supports 423, along the arrangement direction (second direction D2) of the plurality of contact supports 423, and toward each other.

[0084] like Figures 8 to 10 As shown, further, the two reinforcing members 4261 of the reinforcing insert 426 form a through hole 4263, and the push rod 421 passes through the through hole 4263.

[0085] In this embodiment, the push rod 421 passes through the perforation 4263 formed by two reinforcing members 4261, meaning that a portion of the push rod 421 is located between two adjacent contact supports 423. Thus, the portion of the insulating member 422 located between the two contact supports 423 not only covers the reinforcing insert 426 but also a portion of the push rod 421, further improving the structural strength of this portion of the insulating member 422. Furthermore, when the push rod 421, contact supports 423, reinforcing insert 426, and insulating member 422 are connected by injection molding, the perforation 4263 can, to a certain extent, limit the movement of the push rod 421 relative to the contact supports 423 during the molding process, preventing significant displacement of the push rod 421 relative to the contact supports 423.

[0086] like Figure 9 and Figure 11 As shown, the two reinforcing members 4261 of the reinforcing insert 426 are joined together, and two joint seams 4262 are formed at the joint position. The two joint seams 4262 are not collinear.

[0087] In the embodiments of this application, the two butt joints 4262 formed at the positions where the two reinforcing members 4261 meet are not collinear. In this way, even if the part of the insulating member 422 located between two adjacent contact supports 423 cracks, the crack will not crack along a straight line, thus avoiding the overall breakage of the insulating member 422.

[0088] Furthermore, the butt joint 4262 is parallel to the third direction D3, but not limited to this.

[0089] In one embodiment, the reinforcement 4261 is formed by bending a portion of the contact support 423, but is not limited thereto.

[0090] As a modified embodiment, when the reinforcing insert 426 includes two reinforcing members 4261, each reinforcing member 4261 and the corresponding contact support 423 can also be a separate structure. For example, the reinforcing member 4261 and the contact support 423 can be connected by riveting, welding, interference fit, etc. This application does not limit this.

[0091] In one embodiment, the insulating member 422 is made of plastic and is integrally connected to the push rod 421, the contact bracket 423 and the reinforcing insert 426 by injection molding.

[0092] like Figure 8 and Figure 9 As shown, the contact support 423 includes a connecting portion 4231 and two side portions 4232, one end of each side portion 4232 being connected to both ends of the connecting portion 4231 along the first direction D1; the reinforcing insert 426 is connected between the connecting portions 4231 of two adjacent contact supports 423, or the reinforcing insert 426 is connected between two adjacent side portions 4232 of two adjacent contact supports 423.

[0093] Among them, the insulating component 422 covers one end of the push rod 421, the connecting part 4231 and the reinforcing insert 426.

[0094] When the reinforcing insert 426 includes two reinforcing members 4261, the two reinforcing members 4261 of one reinforcing insert 426 are respectively connected between the connecting portions 4231 of two adjacent contact supports 423, or the two reinforcing members 4261 of one reinforcing insert 426 are respectively connected between two adjacent side portions 4232 of two adjacent contact supports 423.

[0095] In one embodiment, the connecting portion 4231 is flat and multiple connecting portions 4231 are located on the same plane.

[0096] Of course, in another embodiment, the contact support 423 can also be inverted U-shaped.

[0097] In one embodiment, the reinforcing insert 426 is a metal part, but it is not limited thereto. For example, the reinforcing insert 426 may also be made of ceramic materials, composite materials, etc.

[0098] It is understood that the reinforcing insert 426 is not limited to including two reinforcing members 4261. In other embodiments, the reinforcing insert 426 may also be an integral part, with the reinforcing insert 426 and the contact support 423 being separately connected and connected between two adjacent contact supports 423.

[0099] When the reinforcing insert 426 is a single piece, the reinforcing insert 426 may have a through hole 4263, and the push rod 421 passes through the through hole 4263.

[0100] It should be noted that the number of contact supports 423 is more than two, such as two, three, four, five, six, etc.

[0101] When the number of contact supports 423 is even, such as two, four, or six, the number of reinforcing inserts 426 is odd, such as one, three, or five. When there is only one reinforcing insert 426, it has a through hole 4263 through which the push rod 421 can pass. When there are three or more reinforcing inserts 426, the middle reinforcing insert 426 has a through hole 4263 through which the push rod 421 can pass, so that the push rod 421 is centered in the first direction D1, while the remaining reinforcing inserts 426 do not need to have through holes 4263. When each of the remaining reinforcing inserts 426 includes two reinforcing members 4261, the two reinforcing members 4261 are joined together, and the resulting joint 4262 can be a zigzag shape.

[0102] When the number of contact supports 423 is odd, such as three, five, or seven, and the number of reinforcing inserts 426 is even, such as two, four, or six, then the middle contact support 423 has a through hole 4263, through which the push rod 421 can be inserted, so that the push rod 421 is centered in the first direction D1, while the reinforcing inserts 426 may not have a through hole 4263. When each reinforcing insert 426 includes two reinforcing members 4261, the two reinforcing members 4261 are joined together, and the resulting joint seam 4262 can be a zigzag shape.

[0103] In summary, the push rod component and relay of the embodiments of this application have at least the following advantages and beneficial effects:

[0104] In this embodiment of the push rod component, a reinforcing insert 426 connects adjacent contact supports 423 among a plurality of side-by-side arranged contact supports 423. Thus, when the insulating member 422 connects the push rod 421 and the plurality of contact supports 423, the portion of the insulating member 422 located between adjacent contact supports 423 is provided with the reinforcing insert 426. The reinforcing insert 426 can improve the structural strength of the central region of the insulating member 422. On the one hand, the reinforcing insert 426 can reduce the risk of deformation of the insulating member 422 during molding, ensuring the consistency of the positions of the plurality of contact supports 423 and ensuring the contact position of the moving and stationary contacts; on the other hand, the reinforcing insert 426 can improve the strength of the central region of the insulating member 422, avoiding the problem of breakage of the push rod component during reciprocating motion.

[0105] Furthermore, the reinforcing member 4261 and the contact support 423 are an integral structure. From the perspective of the number of parts, the push rod component in this embodiment does not increase the number of parts, thus facilitating transportation and not affecting assembly efficiency. From the perspective of processing difficulty, the integral structure of the reinforcing member 4261 and the corresponding contact support 423 reduces processing difficulty. In addition, the two non-collinear butt joints 4262 formed at the mating position of the two reinforcing members 4261 can also prevent the insulation member 422 from breaking as a whole.

[0106] Furthermore, the push rod 421 passes through the perforation 4263 formed by the two reinforcing members 4261, meaning that a portion of the push rod 421 is located between two adjacent contact supports 423. Thus, the portion of the insulating member 422 located between the two contact supports 423 not only covers the reinforcing insert 426 but also a portion of the push rod 421, further improving the structural strength of this portion of the insulating member 422. In addition, when the push rod 421, contact support 423, reinforcing insert 426, and insulating member 422 are connected by injection molding, the perforation 4263 can, to a certain extent, limit the movement of the push rod 421 relative to the contact support 423, preventing significant displacement of the push rod 421 relative to the contact support 423 during the molding process.

[0107] Furthermore, the two butt joints 4262 formed by the positions where the two reinforcing members 4261 meet are not collinear. This way, even if the part of the insulating member 422 located between two adjacent contact supports 423 cracks, the crack will not crack along a straight line, thus avoiding the overall breakage of the insulating member 422.
