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 including the push rod component. 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] A relay includes a stationary contact, a moving contact, and a push rod assembly. The moving contact is mounted on the push rod assembly, and when the push rod assembly moves, it can drive the moving contact to make contact with or separate from the stationary contact.

[0004] In related technologies, the push rod component includes a U-shaped bracket and a fixing plate. The U-shaped bracket and the fixing plate are usually connected by riveting, which has the following problems: 1. When the flat fixing plate is subjected to riveting force, the middle area is prone to arching, which can cause the push rod component to jam when moving; 2. When the bent fixing plate is subjected to riveting force, tooling is needed to support the inner side of the fixing plate, making the assembly process more complicated; 3. When multiple U-shaped brackets are arranged side by side, the space between two adjacent U-shaped brackets is insufficient, making it impossible to rivet. Utility Model Content

[0024] According to some embodiments of this application, the blocking structure further includes a fixing member and an elastic member. The fixing member is fixedly connected to the contact cavity, and the seesaw is oscillatingly connected to the fixing member. The elastic member is used to provide an elastic force to the seesaw so that when the relay is not energized, the seesaw can be held in a position where it is not in contact with either the first moving component or the second moving component.

[0025] According to some embodiments of this application, the fastener includes a connecting portion and two spaced-apart side portions, the connecting portion being connected between the two side portions, the seesaw being located within the space enclosed by the two side portions and the connecting portion, and the elastic element being located between the connecting portion and the seesaw.

[0026] According to some embodiments of this application, the blocking structure further includes a first limiting structure and a second limiting structure. The first limiting structure is disposed on the connecting portion, and the second limiting structure is disposed on the seesaw. The elastic member has a third limiting structure and a fourth limiting structure. The first limiting structure and the third limiting structure are mutually limiting and cooperating, and the second limiting structure and the fourth limiting structure are mutually limiting and cooperating.

[0027] According to some embodiments of this application, the first limiting structure includes two lugs, which are respectively connected to both ends of the connecting portion in the width direction and extend from the connecting portion toward the seesaw. The elastic element is a spring, and the two ends of the spring abut against the connecting part and the seesaw respectively. One end of the spring is the third limiting structure, and the other end is the fourth limiting structure. The third limiting structure is located between the two lugs. The second limiting structure protrudes from the surface of the seesaw facing the spring and is inserted into the fourth limiting structure.

[0029] According to some embodiments of this application, the blocking structure further includes a pin connecting the two sides; The contact cavity has a yoke plate, and the seesaw has a bent section located on the side of the pin facing or away from the yoke plate, and the bent section is rotatably engaged with the pin.

[0030] According to some embodiments of this application, 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.

[0031] According to some embodiments of this application, the first static contact component includes two first static contacts, the second static contact component includes two second static contacts, and the two first static contacts correspond to the two second static contacts respectively; the first moving component includes a first moving contact component, and the second moving component includes two second moving contact components. 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. When the relay is in the second state, both ends of each second moving contact component are in contact with the corresponding first stationary contact and the second stationary contact, respectively, and the first moving contact component is separated from the first stationary contact.

[0032] According to some embodiments of this application, the first static contact includes a static component and a conductive component, the conductive component being connected to the static component and extending from the static component toward the second static contact, the conductive component being used to contact the first dynamic contact assembly and the second dynamic contact assembly.

[0033] According to some embodiments of this application, the blocking structure is located between the first moving component and the second moving component.

[0034] According to some embodiments of this application, the relay further includes a contact cavity, and the blocking structure is mounted in the contact cavity; or... The relay also includes a contact cavity having a yoke plate, and the blocking structure is mounted on the yoke plate.

[0035] An embodiment of the above application has at least the following advantages or beneficial effects: The push rod component of this application utilizes the characteristic that the deformable part can deform under external force to connect the first component and the second component. Compared with the riveting method used in related technologies, the push rod component of this application has the following advantages: 1. External force applied to the deformable part will not cause the middle area of ​​the second component to arch, thereby avoiding jamming during the movement of the push rod component; 2. Since the first component and the second component are not connected by riveting, there is no need to configure additional tooling to support the first component and / or the second component, simplifying the assembly process; 3. When the push rod component includes multiple second components arranged side by side, related technologies require applying force along the arrangement direction of the multiple second components, which can lead to the problem of not being able to connect the first component and the second component. In this application embodiment, the deformable part can deform along a direction perpendicular to the arrangement direction of the multiple second components, and then the force-applying tool can be located between adjacent second components to apply force to the deformable part, thereby enabling the connection of the first component and the second component.

[0036] Furthermore, the support portion of the second component passes through the notch in the first component and supports the first component. The support portion increases the contact area between the first and second components, thereby improving the stability after the first and second components are connected. In addition, the support portion can also cooperate with other components, for example, the support portion can be a first stop portion used to counteract the seesaw.

[0037] Furthermore, the stiffness of the reinforcing part is greater than that of the deforming part. The reinforcing part is located inside the opening, while the deforming part is located outside the opening. In this way, the reinforcing part can provide higher support strength after being inserted into the opening, and the deforming part is more likely to deform when subjected to external force.

[0038] Furthermore, when the two protrusions are subjected to external force, they can deform in a direction that moves closer to each other, so that L1 < L2. This can confine the protrusions within the opening, thereby preventing the first component from separating from the second component.

[0039] Furthermore, by providing a blocking structure within the contact cavity, the blocking structure is configured to prevent the second moving component from contacting the second stationary contact component when the first moving component contacts the first stationary contact component, and to prevent the first moving component from contacting the first stationary contact component when the second moving component contacts the second stationary contact component. This avoids the first moving component and the second moving component from simultaneously contacting the first stationary contact component and the second stationary contact component, thereby preventing the relay from short-circuiting or even exploding due to all contacts being in a closed state.

[0040] Furthermore, the blocking structure includes a seesaw. When one of the first moving component and the second moving component moves, it can drive the seesaw to swing, thereby achieving the effect that the seesaw can block the other of the first moving component and the second moving component from moving, thus avoiding the short circuit problem caused by the simultaneous closure of the first moving component and the second moving component.

[0041] Furthermore, when one of the first and second force-bearing parts of the seesaw tilts upward, the other tilts downward. By setting up a seesaw, the first and second moving components can be controlled simultaneously, which has the advantages of simple structure and space saving.

[0042] Furthermore, the first and second force-bearing parts protrude from the side surface of the substrate facing the yoke plate, reducing the contact area between the first stop and the seesaw and between the second stop and the seesaw, thereby preventing the generation of scrapes due to excessive friction between the first stop and the seesaw and between the second stop and the seesaw.

[0043] Furthermore, the elastic element and the connecting part are limited by the first limiting structure and the third limiting structure, and the elastic element and the seesaw are limited by the second limiting structure and the fourth limiting structure, which can prevent the elastic element from coming out of the connecting part and the seesaw.

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.

[0076] The term "contact" refers to direct or indirect contact between the moving component 40 and the stationary contact component 30, allowing current to flow between them; the term "separation" refers to the disconnection between the moving component 40 and the stationary contact component 30, preventing current from flowing between them.

[0077] 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.

[0078] Of course, in other embodiments, one of the first state and the second state can be a closed state and the other is an open state.

[0079] 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.

[0080] 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.

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.

[0085] like Figure 2 and Figure 3 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.

[0086] 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.

[0087] 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.

[0088] The yoke plate 22 has a first through hole 221 and a second through hole 222.

The second mounting base 422 is connected to the second push rod 421, and the second contact bracket 423 is connected to the second mounting base 422. The second moving contact assembly 425 is mounted within the second contact bracket 423 and is used to simultaneously contact or separate from the first stationary contact assembly 31 and the second stationary contact assembly 32.

[0091] 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 411.

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 421. The second magnetic circuit portion 62 is configured to drive the second push rod 421 to move in response to a second input signal, causing the second push rod 421 to contact or separate from the second moving contact assembly 425 and the second stationary contact assembly 32.

[0092] 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.

[0093] When the external circuit controlled by the relay is in series, the first moving component 40a is in contact with the first stationary contact component 31, while the second moving component 40b is separated from the second stationary contact component 32. When the external circuit controlled by the relay is in parallel, the second moving component 40b is in contact with both the first stationary contact component 31 and the second stationary contact component 32, while the first moving component 40a is separated from the first stationary contact component 31.

[0094] In the embodiments of this application, when the external circuit controlled by the relay is in a series connection state, both ends of the first moving contact component 415 are simultaneously in contact with the two first stationary contacts 311, and the second moving contact component 425 is separated from the second stationary contact 321, so that the two first stationary contacts 311 are connected in series through the first moving contact component 415. When the external circuit controlled by the relay is in a parallel connection state, both ends of each second moving contact component 425 are in contact with the corresponding first stationary contact 311 and second stationary contact 321, and the first moving contact component 415 is separated from the first stationary contact 311, so that the two sets of corresponding first stationary contact components 31 and second stationary contact components 32 are connected in parallel.

[0095] like Figure 5 As shown, the first stationary contact 311 includes a stationary component 311a and a conductive component 311b. The conductive component 311b is connected to the stationary component 311a and extends from the stationary component 311a toward the second stationary contact 321. The conductive component 311b is used to contact the first moving contact assembly 415 and the second moving contact assembly 425.

[0096] In one embodiment, the conductive element 311b is connected to the side surface of the stationary element 311a facing the yoke plate 22. When the external circuit controlled by the relay is in series, the first moving contact assembly 415 contacts the conductive element 311b; when the external circuit controlled by the relay is in parallel, one end of each of the two second moving contact assemblies 425 contacts the two conductive elements 311b, and the other end of each of the two second moving contact assemblies 425 contacts the two second stationary contacts 321.

[0097] Of course, in other embodiments, the conductive element 311b may also be connected to the outer peripheral side of the stationary element 311a. When the relay is in series, the first moving contact assembly 415 is in contact with the stationary element 311a; when the relay is in parallel, one end of each of the two second moving contact assemblies 425 is in contact with the two conductive elements 311b, and the other end of each of the two second moving contact assemblies 425 is in contact with the two second stationary contacts 321.

[0098] In one implementation, such as Figure 5 As shown, the first movable contact assembly 415 has one or more first movable contact elements 4151. When the first movable contact assembly 415 has multiple first movable contact elements 4151, the multiple first movable contact elements 4151 are arranged side by side along a third direction D3. Each second movable contact assembly 425 has one or more second movable contact elements 4251. When the second movable contact assembly 425 has multiple second movable contact elements 4251, the multiple second movable contact elements 4251 are arranged side by side along a first direction D1.

[0099] like Figures 6 to 9 As shown, the relay in this embodiment of the application further includes a blocking structure 50, which is disposed within the contact chamber 23 and located between the first moving component 40a and the second moving component 40b. The blocking structure 50 is configured to prevent the second moving component 40b from contacting the second stationary contact component 32 when the first moving component 40a contacts the first stationary contact component 31, and to prevent the first moving component 40a from contacting the first stationary contact component 31 when the second moving component 40b contacts the second stationary contact component 32.

[0100] The relay in this embodiment of the application provides a blocking structure 50 in the contact cavity 20. The blocking structure 50 is configured to prevent the second moving component 40b from contacting the second stationary contact component 32 when the first moving component 40a contacts the first stationary contact component 31, and to prevent the first moving component 40a from contacting the first stationary contact component 31 when the second moving component 40b contacts the second stationary contact component 32. This avoids the first moving component 40a and the second moving component 40b from contacting the first stationary contact component 31 and the second stationary contact component 32 at the same time, thereby avoiding the problem of short circuit or even explosion caused by all contacts being in a closed state.

[0101] In one embodiment, the blocking structure 50 can be mounted on the yoke plate 22. Of course, in other embodiments, the blocking structure 50 can also be mounted on the insulating cover 21.

[0102] like Figures 7 to 9 As shown, the blocking structure 50 includes a seesaw 51, which is swayable relative to the contact cavity 20. The seesaw 51 has a first force-receiving part 511 and a second force-receiving part 512. When the relay is in the first state, the first moving component 40a is in contact with the first force-receiving part 511, and the second force-receiving part 512 stops the second moving component 40b from moving to the position of contacting the second stationary contact component 32. When the relay is in the second state, the second moving component 40b is in contact with the second force-receiving part 512, and the first force-receiving part 511 stops the first moving component 40a from moving to the position of contacting the first stationary contact component 31.

[0103] In one embodiment, when the relay is in the first state, the second moving component 40b is in contact with or separates from the second force-receiving part 512; when the relay is in the second state, the first moving component 40a is in contact with or separates from the first force-receiving part 511.

[0104] In detail, when the relay is in the first state and the second moving component 40b is in contact with the second force receiving part 512, the second force receiving part 512 can block the movement of the second moving component 40b; when the relay is in the first state and the second moving component 40b is separated from the second force receiving part 512, the second moving component 40b can move toward the direction of the second stationary contact component 32, but when the second moving component 40b moves to the position of contacting the second force receiving part 512, the second force receiving part 512 can block the second moving component 40b from continuing to move.

[0105] Similarly, when the relay is in the second state and the first moving component 40a is in contact with the first force receiving part 511, the first force receiving part 511 can block the movement of the first moving component 40a; when the relay is in the second state and the first moving component 40a is separated from the first force receiving part 511, the first moving component 40a can move toward the direction of the first stationary contact component 31, but when the first moving component 40a moves to the position of contacting the first force receiving part 511, the first force receiving part 511 can block the first moving component 40a from continuing to move.

[0106] The first moving assembly 40a includes a first stop 414, located on the side of the seesaw 51 opposite to the first stationary contact assembly 31. When the relay is in the first state, the first stop 414 abuts against the first force-bearing part 511. The second moving assembly 40b includes a second stop 424, located on the side of the seesaw 51 opposite to the second stationary contact assembly 32. When the relay is in the second state, the second stop 424 abuts against the second force-bearing part 512. The first force-bearing part 511 and the first stop 414 have overlapping first projections on a target plane, and the second force-bearing part 512 and the second stop 424 have overlapping second projections on the target plane. The target plane is perpendicular to the second direction D2.

[0107] like Figure 8 and Figure 9As shown, when the relay switches from the second state to the first state, the first moving component 40a drives the seesaw 51 to swing along the first swing direction D4, so that the first force-receiving part 511 moves away from the yoke plate 22, while the second force-receiving part 512 moves closer to the yoke plate 22; when the relay switches from the first state to the second state, the second moving component 40b drives the seesaw 51 to swing along the second swing direction D5, so that the second force-receiving part 512 moves away from the yoke plate 22, while the first force-receiving part 511 moves closer to the yoke plate 22; the first swing direction D4 is opposite to the second swing direction D5.

[0108] In the embodiments of this application, when one of the first moving component 40a and the second moving component 40b moves, it can drive the seesaw 51 to swing, thereby achieving the effect that the seesaw 51 can block the other moving component 40a and the second moving component 40b, avoiding the short circuit problem caused by the simultaneous closure of the first moving component 40a and the second moving component 40b.

[0109] like Figure 8 As shown, when the relay is in the first state, the distance between the first force-receiving part 511 and the yoke plate 22 is H1, and the distance between the second force-receiving part 512 and the yoke plate 22 is H2, where H1 > H2.

[0110] like Figure 9 As shown, when the relay is in the second state, the distance between the second force-receiving part 512 and the yoke plate 22 is H3, and the distance between the first force-receiving part 511 and the yoke plate 22 is H4, where H3 > H4.

[0111] In the embodiments of this application, when one of the first force-receiving part 511 and the second force-receiving part 512 of the seesaw 51 tilts upward, the other tilts downward. By setting a seesaw 51, the first moving component 40a and the second moving component 40b can be controlled simultaneously, which has the advantages of simple structure and space saving.

[0112] like Figures 10 to 12 As shown, the blocking structure 50 also includes a fixing member 53, which is fixedly connected to the contact cavity 20, and the seesaw 51 is oscillatingly connected to the fixing member 53.

[0113] In one embodiment, the fastener 53 can be fixedly connected to the yoke plate 22, or fixedly connected to the insulating cover 21, or the fastener 53 can be fixedly connected to both the yoke plate 22 and the insulating cover 21.

[0114] The blocking structure 50 also includes an elastic element 54, which provides an elastic force to the seesaw 51 so that the seesaw 51 can remain in a position where it is not in contact with either the first moving component 40a or the second moving component 40b when the relay is not energized.

[0115] In this context, "unenergized" means that the relay coil is not energized and is in its natural position when it is in an unexcited state.

[0116] The fixing member 53 includes a fixing part 533, a connecting part 531, and two spaced-apart side parts 532. The fixing part 533 is fixedly connected to the yoke plate 22. One end of each side part 532 is connected to the fixing part 533, and the other end is connected to the connecting part 531. The seesaw 51 is located within the space enclosed by the two side parts 532 and the connecting part 531. The elastic member 54 is located between the connecting part 531 and the seesaw 51.

[0117] In one embodiment, the elastic element 54 is a spring 54a, one end of which abuts against the connecting portion 531, and the other end of which abuts against the seesaw 51.

[0118] like Figure 11 and Figure 12 As shown, the seesaw 51 has a base plate 513 and two connecting ears 514, which are rotatably connected to two sides 532 respectively. A first force-bearing part 511 and a second force-bearing part 512 protrude from the surface of the base plate 513 facing the yoke plate 22.

[0119] In the embodiments of this application, the first force-receiving part 511 and the second force-receiving part 512 protrude from the side surface of the substrate 513 facing the yoke plate 22, reducing the contact area between the first stop part 414 and the seesaw 51 and the second stop part 424 and the seesaw 51, thereby avoiding the generation of scraping due to large friction between the first stop part 414 and the seesaw 51 and between the second stop part 424 and the seesaw 51.

[0120] In one embodiment, the first force-receiving part 511 and the second force-receiving part 512 may be hemispherical, but are not limited thereto.

[0121] like Figure 11 and Figure 12 As shown, the blocking structure 50 also includes a first limiting structure 55 and a second limiting structure 56. The first limiting structure 55 is provided on the connecting part 531, and the second limiting structure 56 is provided on the seesaw 51. The elastic member 54 has a third limiting structure 541 and a fourth limiting structure 542. The first limiting structure 55 and the third limiting structure 541 are in a limiting cooperation, and the second limiting structure 56 and the fourth limiting structure 542 are in a limiting cooperation.

[0122] In the embodiments of this application, the elastic member 54 and the connecting part 531 are limited and engaged by the first limiting structure 55 and the third limiting structure 541, and the elastic member 54 and the seesaw 51 are limited and engaged by the second limiting structure 56 and the fourth limiting structure 542, which can prevent the elastic member 54 from coming out of the connecting part 531 and the seesaw 51.

[0123] like Figure 11 and Figure 12 As shown, the first limiting structure 55 includes two lugs 551, which are respectively connected to the two ends of the connecting part 531 in the width direction and extend from the connecting part 531 toward the seesaw 51; the two ends of the spring 54a abut against the connecting part 531 and the seesaw 51 respectively, one end of the spring 54a is the third limiting structure 541, and the other end is the fourth limiting structure 542. The third limiting structure 541 is located between the two lugs 551, and the second limiting structure 56 protrudes from the surface of the seesaw 51 facing the spring 54a and is inserted into the fourth limiting structure 542.

[0124] like Figures 13 to 16 As shown, the similarities between the blocking structure 50 of the second embodiment and the blocking structure 50 of the first embodiment will not be repeated here. The differences are as follows: The blocking structure 50 of this embodiment includes a seesaw 51, a fixing member 53, a pin 57, and an elastic member 54. The pin 57 is connected between the two sides 532 of the fixing member 53, and the seesaw 51 is rotatably connected to the pin 57. The elastic member 54 is a leaf spring 54b. One of the first limiting structure 55 and the third limiting structure 541 is a first limiting protrusion 552 and the other is a first limiting hole 5411, with the first limiting protrusion 552 confined within the first limiting hole 5411. One of the second limiting structure 56 and the fourth limiting structure 542 is a second limiting protrusion 561 and the other is a second limiting hole 5421, with the second limiting protrusion 561 confined within the second limiting hole 5421.

[0125] In one embodiment, the first limiting structure 55 is a first limiting protrusion 552, and the third limiting structure 541 is a first limiting hole 5411. The first limiting protrusion 552 protrudes from the connecting portion 531, and the first limiting hole 5411 is formed on the leaf spring 54b. The second limiting structure 56 is a second limiting protrusion 561, and the fourth limiting structure 542 is a second limiting hole 5421. The seesaw 51 is provided with two second limiting protrusions 561, which are arranged at intervals along a third direction D3. Both ends of the leaf spring 54b have second limiting holes 5421, and the two second limiting protrusions 561 are respectively confined within the two second limiting holes 5421.

[0126] like Figures 17 to 20 As shown, the similarities between the blocking structure 50 of the third embodiment and the blocking structure 50 of the second embodiment will not be repeated here. The differences are as follows: The seesaw 51 has a bent section 5131, which is located on the side of the pin 57 facing away from the yoke plate 22, and the bent section 5131 is rotatably engaged with the pin 57.

[0127] like Figure 21 and Figure 22 As shown, the similarities between the blocking structure 50 of the fourth embodiment and the blocking structure 50 of the third embodiment will not be repeated here. The differences are as follows: The fixing part 533 is connected to the connecting part 531. The seesaw 51 has a bent section 5131, which is located on the side of the pin 57 facing the yoke plate 22, and the bent section 5131 is rotatably engaged with the pin 57.

[0128] like Figures 23 to 25 As shown, the first contact support 413 of the first push rod component 416 includes a first component 4131 and a second component 4132. The first component 4131 has two spaced openings 4133; the second component 4132 has two protrusions 4134, which are respectively inserted into the two openings 4133; the protrusions 4134 have deformable portions 41341 located outside the openings 4133, and the deformable portions 41341 of the two protrusions 4134 can deform under external force to connect the first component 4131 and the second component 4132.

[0129] When assembling the first component 4131 and the second component 4132 in this embodiment, the protrusion 4134 of the second component 4132 can be inserted into the opening 4133 of the first component 4131, and then an external force is applied to the deformable part 41341 of the protrusion 4134 to cause the deformable part 41341 to deform, thereby connecting the first component 4131 and the second component 4132.

[0130] The push rod component of this application embodiment utilizes the characteristic that the deformable part 41341 can deform under external force to connect the first component 4131 and the second component 4132. Compared with the riveting method used in related technologies, the push rod component of this application has the following advantages: 1. When external force is applied to the deformable part 41341, it will not cause the middle area of ​​the second component 4132 to arch, thereby avoiding jamming when the push rod component moves; 2. Since the first component 4131 and the second component 4132 are not connected by riveting, there is no need to configure additional tooling to support the first component 4131 and / or the second component 4132, simplifying the assembly process; 3. When the push rod component includes multiple second components arranged side by side, related technologies require applying force along the arrangement direction of the multiple second components, which has the problem of not being able to connect the first component and the second component. In this embodiment, the deformable part 41341 can deform along the direction perpendicular to the arrangement direction of the plurality of second components, and then the force-applying tool can be located between adjacent second components to apply force to the deformable part, thereby enabling the first component 4131 and the second component 4132 to be connected.

[0131] In one embodiment, the deformation directions of the deformation portions 41341 of the two protrusions 4134 are the same or opposite. For example, the deformation portions 41341 of the two protrusions 4134 both deform along the third direction D3, or the deformation portions 41341 of the two protrusions 4134 both deform along the second direction D2.

[0132] Furthermore, when the deformation directions of the deformation portions 41341 of the two protrusions 4134 are opposite, the two deformation portions 41341 are configured to be close to each other or far apart from each other.

[0133] For example, in one embodiment, the two deformable portions 41341 may move closer to or further away from each other in the first direction D1.

[0134] Of course, the two deformable parts 41341 can also move closer to each other or further apart in other directions.

[0135] like Figures 23 to 25 As shown, the first component 4131 also has a notch 4136, and the second component 4132 also has a support portion 4135, which passes through the notch 4136 and supports the first component 4131.

[0136] In this embodiment, the support portion 4135 of the second component 4132 passes through the notch 4136 of the first component 4131 and supports the first component 4131. The support portion 4135 can increase the contact area between the first component 4131 and the second component 4132, thereby improving the stability after the first component 4131 and the second component 4132 are connected. In addition, the support portion 4135 can also cooperate with other components, for example, the support portion 4135 can be a first stop portion 414, used to abut against the seesaw 51.

[0137] When the first stop portion 414 is a support portion 4135, the first stop portion 414 is directly formed using the support portion 4135 of the second component 4132, without the need for an additional stop portion, resulting in a simpler structure. Furthermore, the support portion 4135 is not assembled with the first component 4131 by insertion, reducing assembly difficulty.

[0138] It should be noted that the first stop 414 may be provided on the first push rod member 416, for example: the first stop 414 may be provided on the first member 4131; or, the first stop 414 may be provided on the second member 4132; or, the first stop 414 may be provided on the first mounting base 412.

[0139] In one embodiment, the notch 4136 is located between two openings 4133; and / or, the support 4135 is located between two protrusions 4134.

[0140] like Figure 25As shown, the protrusion 4134 also has a reinforcing portion 41342 located within the opening 4133, the deformable portion 41341 is connected to the reinforcing portion 41342, and the stiffness of the deformable portion 41341 is less than the stiffness of the reinforcing portion 41342.

[0141] In the embodiments of this application, the stiffness of the reinforcing part 41342 is greater than the stiffness of the deformable part 41341. The reinforcing part 41342 is located inside the opening 4133, and the deformable part 41341 is located outside the opening 4133. Thus, the reinforcing part 41342 can provide higher support strength after being inserted into the opening 4133, and the deformable part 41341 is more likely to deform when subjected to external force.

[0142] In one embodiment, along the arrangement direction of the two openings 4133, the size of the deformable part 41341 is smaller than the size of the reinforcing part 41342.

[0143] Of course, in other embodiments, the thickness of the deformable part 41341 may be designed to be less than the thickness of the reinforcing part 41342.

[0144] In one embodiment, the first push rod 411, the first component 4131, and the first mounting base 412 are integrally formed and connected. For example, the first mounting base 412 is made of plastic material, and the first push rod 411, the first component 4131, and the first mounting base 412 are integrally connected by injection molding.

[0145] In another embodiment, the first push rod 411, the second component 4132, and the first mounting base 412 are integrally formed and connected. For example, the first mounting base 412 is made of plastic material, and the first push rod 411, the second component 4132, and the first mounting base 412 are integrally connected by injection molding.

[0146] like Figures 26 to 28 As shown, the shortest distance between the deformed portions 41341 of the two protrusions 4134 is L1, and the shortest distance between the adjacent walls of the two openings 4133 is L2, where L1 < L2.

[0147] In the embodiments of this application, when the deformable portions 41341 of the two protrusions 4134 are subjected to external force, they can deform in a direction that moves closer to each other, so that L1 < L2. This can confine the protrusions 4134 within the opening 4133, thereby preventing the first component 4131 from separating from the second component 4132.

[0148] In other embodiments, the deformable portions 41341 of the two protrusions 4134 may also deform in directions that are far apart from each other.

[0149] In summary, the relays of the embodiments of this application have at least the following advantages and beneficial effects: The push rod component of this application embodiment utilizes the characteristic that the deformable part 41341 can deform under external force to connect the first component 4131 and the second component 4132. Compared with the riveting method used in related technologies, the push rod component of this application has the following advantages: 1. When external force is applied to the deformable part 41341, it will not cause the middle area of ​​the second component 4132 to arch, thereby avoiding jamming when the push rod component moves; 2. Since the first component 4131 and the second component 4132 are not connected by riveting, there is no need to configure additional tooling to support the first component 4131 and / or the second component 4132, simplifying the assembly process; 3. When the push rod component includes multiple second components arranged side by side, related technologies require applying force along the arrangement direction of the multiple second components, which has the problem of not being able to connect the first component and the second component. In this embodiment, the deformable part 41341 can deform along the direction perpendicular to the arrangement direction of the plurality of second components, and then the force-applying tool can be located between adjacent second components to apply force to the deformable part, thereby enabling the first component 4131 and the second component 4132 to be connected.

[0150] Furthermore, the support portion 4135 of the second component 4132 passes through the notch 4136 of the first component 4131 and supports the first component 4131. The support portion 4135 can increase the contact area between the first component 4131 and the second component 4132, thereby improving the stability after the first component 4131 and the second component 4132 are connected. In addition, the support portion 4135 can also cooperate with other components, for example, the support portion 4135 can be a first stop portion 414, used to abut against the seesaw 51.

[0151] Furthermore, the stiffness of the reinforcing part 41342 is greater than that of the deformable part 41341. The reinforcing part 41342 is located inside the opening 4133, while the deformable part 41341 is located outside the opening 4133. Thus, the reinforcing part 41342 can provide higher support strength after being inserted into the opening 4133, and the deformable part 41341 is more likely to deform when subjected to external force.

[0152] Furthermore, when the two protrusions 4134 are subjected to external force, the deformable portions 41341 of the two protrusions 4134 can deform in the direction of moving closer to each other, so that L1 < L2. This can confine the protrusions 4134 within the opening 4133, thereby preventing the first member 4131 from separating from the second member 4132.

[0153] Furthermore, by providing a blocking structure 50 within the contact cavity 20, the blocking structure 50 is configured to prevent the second moving component 40b from contacting the second stationary contact component 32 when the first moving component 40a contacts the first stationary contact component 31, and to prevent the first moving component 40a from contacting the first stationary contact component 31 when the second moving component 40b contacts the second stationary contact component 32. This avoids the first moving component 40a and the second moving component 40b from simultaneously contacting the first stationary contact component 31 and the second stationary contact component 32, thereby preventing the relay from short-circuiting or even exploding due to all contacts being in a closed state.

[0154] Furthermore, the blocking structure 50 includes a seesaw 51. When one of the first moving component 40a and the second moving component 40b moves, it can drive the seesaw 51 to swing, thereby achieving the effect that the seesaw 51 can block the other of the first moving component 40a and the second moving component 40b from moving, thus avoiding the short circuit problem caused by the simultaneous closure of the first moving component 40a and the second moving component 40b.

[0155] Furthermore, when one of the first force-bearing part 511 and the second force-bearing part 512 of the seesaw 51 tilts upward, the other tilts downward. By setting up a seesaw 51, the first moving component 40a and the second moving component 40b can be controlled simultaneously, which has the advantages of simple structure and space saving.

[0156] Furthermore, the first force-bearing part 511 and the second force-bearing part 512 protrude from the side surface of the substrate 513 facing the yoke plate 22, reducing the contact area between the first stop part 414 and the seesaw 51 and the second stop part 424 and the seesaw 51, thereby avoiding the generation of scraping due to large friction between the first stop part 414 and the seesaw 51 and between the second stop part 424 and the seesaw 51.

[0157] Furthermore, the elastic member 54 is limited and engaged with the connecting part 531 by the first limiting structure 55 and the third limiting structure 541, and the elastic member 54 is limited and engaged with the seesaw 51 by the second limiting structure 56 and the fourth limiting structure 542, which can prevent the elastic member 54 from coming off between the connecting part 531 and the seesaw 51.
