Description

Technical Field

[0001] This application relates to the field of relay technology, and in particular to relay leads, contact components, and relays. Background Technology

[0002] Relays, as common components for circuit switching control, are widely used in industrial control, smart homes, automotive electronics, and other fields. In related technologies, relays typically connect to external circuits via leads, for example, by connecting the relay's moving contact to an external circuit. Relays usually have protrusions stamped directly onto the leads, and the external circuit is riveted to these protrusions. However, to meet the space requirements of the riveted structure and avoid interference with other internal components of the relay, a large area of ​​raw material often needs to be cut from the leads. This not only results in a significant waste of expensive materials and increases processing costs, but also compromises the structural integrity of the leads themselves, affecting their current-carrying capacity and mechanical strength. Summary of the Invention

[0003] Therefore, it is necessary to address the issues of raw material waste and high processing costs associated with lead-out pieces by providing a relay lead-out piece, contact assembly, and relay.

[0004] A relay lead, the lead comprising:

[0005] A connection body configured to be disposed inside the housing of a relay;

[0006] The lead-out component is a separate structure from the connecting body. The lead-out component includes a fixed section and a lead-out section. The fixed section is at least partially configured to be disposed inside the housing and connected to the connecting body. The lead-out section is configured to be disposed outside the housing and connected to the fixed section. The lead-out section is configured to be electrically connected to an external line.

[0007] In one embodiment, the lead-out section is provided with a lead-out protrusion, and the lead-out section is configured to be riveted to an external line through the lead-out protrusion;

[0008] Alternatively, the lead-out section is provided with a lead-out through hole, and the lead-out section is configured to be riveted to an external line through the lead-out through hole.

[0011] Alternatively, the fixing segment may have a connecting protrusion, and the connecting body may have a connecting through hole, with the fixing segment riveted to the connecting body via the connecting protrusion and the connecting through hole.

[0012] In one embodiment, the fixed segment and the lead-out segment are arranged sequentially along a first direction;

[0013] The number of connecting protrusions is multiple, and the multiple connecting protrusions are arranged at intervals along the first direction. The number of connecting through holes is multiple, and the fixing segment is riveted to the connecting body through the multiple connecting through holes and the multiple connecting protrusions.

[0014] In one embodiment, the fixing segment is plugged into the connecting body.

[0015] In one embodiment, the fixing segment is provided with a connecting groove, the connecting body is provided with a connecting protrusion, and the connecting protrusion of the connecting body is inserted into the connecting groove of the fixing segment;

[0016] Alternatively, the fixing segment may have a connecting protrusion, and the connecting body may have a connecting groove, with the fixing segment inserted into the connecting groove of the connecting body via the connecting protrusion.

[0017] In one embodiment, the lead-out member further includes a connecting segment connected between the lead-out segment and the fixing segment, the connecting segment being configured to be partially located inside the housing and partially located outside the housing.

[0018] In one embodiment, the fixed segment, the connecting segment, and the lead-out segment are arranged sequentially along a first direction;

[0019] In the second direction, the size of the connecting segment is less than or equal to the size of the fixed segment and the size of the lead-out segment, wherein the second direction is perpendicular to the first direction and the thickness direction of the lead-out piece.

[0020] In one embodiment, the fixing segment, the connecting segment, and the lead-out segment are integrally formed.

[0021] A contact assembly, the contact assembly comprising:

[0022] A stationary contact element, wherein the stationary contact element has a stationary contact point;

[0023] A movable contact, wherein the movable contact has a movable contact point capable of making contact with the stationary contact point to conduct electricity; and

[0024] The lead-out piece described in any of the above embodiments is connected to the moving contact.

[0027] case;

[0028] In the contact assembly described above, the fixing section of the lead-out piece of the contact assembly is at least partially disposed within the housing, while the lead-out section is disposed outside the housing.

[0029] The aforementioned relay's lead-out piece, contact assembly, and relay itself, because the lead-out piece is designed as a separate structure comprising the connecting body and the lead-out component, allow the connecting body and the lead-out component to be independently molded according to their respective assembly and connection requirements. Therefore, the connecting body is indirectly connected to external circuits via the lead-out component. This eliminates the need for large-area cutting and complex bulging of the connecting body for connecting to external circuits, simplifying the lead-out piece's manufacturing process, reducing waste of precious metals such as copper in the connecting body, and lowering costs. Furthermore, the lead-out component can be precision stamped separately on small-sized materials, resulting in higher material utilization. Attached Figure Description

[0057] Please see Figures 1 to 5As shown, this application embodiment provides a lead-out piece 500 for a relay 1, a contact assembly 10 including the lead-out piece 500, and a relay 1. The relay 1 in this application embodiment can be an electromagnetic relay 1, but is not limited to this. Specifically, in this application embodiment, the relay 1 includes a contact assembly 10 and a housing 20, and may also include other components such as an electromagnetic mechanism. The contact assembly 10 includes a stationary contact 110, a moving contact 210, and the lead-out piece 500. The stationary contact 110 has a stationary contact 130, and the moving contact 210 has a moving contact 230. The moving contact 230 can make contact with the stationary contact 130 to conduct electricity. The lead-out piece 500 is used to connect to an external circuit 2, such as a sampling signal line. The sampling signal line is a detection line led out from the relay 1 or its associated module, used to acquire electrical signals related to the operating state of the relay 1 or the main circuit without damaging the main circuit, for monitoring, control, measurement, and protection purposes. The stationary contact 110 and the moving contact 210 are respectively connected to the corresponding circuit terminals of the relay 1, and cooperate with other components such as the electromagnetic mechanism of the relay 1, enabling the relay 1 to realize the circuit on / off control function. The lead-out piece 500 includes a connecting body 510 and a lead-out piece 520. The connecting body 510 of the lead-out piece 500 is connected to the moving contact 210, and there is electrical conductivity between the connecting body 510 and the moving contact 210. The lead-out piece 520 includes a fixed section 521 and a lead-out section 522. The fixed section 521 of the lead-out piece 520 is at least partially disposed within the housing 20, and the lead-out section 522 is disposed outside the housing 20, for electrical connection with the external circuit 2, allowing the moving contact 210 to be electrically connected to the external circuit 2 through the lead-out piece 500. By employing the lead-out piece 500 in the relay 1 and contact assembly 10 of this application embodiment, the processing technology is simplified, the waste of precious metals such as copper in the lead-out piece 500 is reduced, and costs are lowered.

[0058] See Figures 1 to 5As shown, the lead-out piece 500 of relay 1 includes a connecting body 510 and a lead-out member 520. The lead-out piece 500 can be made of conductive materials such as copper. The connecting body 510 is configured to be disposed inside the housing 20 of relay 1, and is connected to and conducts electricity with the moving contact 210 located within the housing 20. The shape of the connecting body 510 can be adapted to the internal shape of the housing 20; for example, the connecting body 510 can be roughly straight. The lead-out member 520 and the connecting body 510 are separate structures, manufactured independently and then joined to form the lead-out piece 500. The lead-out member 520 includes a fixed section 521 and a lead-out section 522, with the lead-out section 522 connected to the fixed section 521. The fixed section 521 is at least partially configured to be disposed inside the housing 20 of the relay 1, meaning that at least a portion of the structure of the fixed section 521 is located within the housing 20. The fixed section 521 is connected to the connecting body 510 located within the housing 20, and there is electrical conductivity between the fixed section 521 and the connecting body 510, ensuring that current can be transmitted between the moving contact 210, the connecting body 510, the fixed section 521, and the lead-out section 522. The lead-out section 522 is configured to be disposed outside the housing 20 of the relay 1 for electrical connection to an external circuit 2. For example, the lead-out section 522 can be connected to a sampling signal line, establishing a current transmission channel between the internal circuit of the relay 1 and the external circuit 2 to achieve functions such as signal detection.

[0059] Through the above structural design, in this embodiment, the lead-out piece 500 is configured as a split structure including a connecting body 510 and a lead-out piece 520. The connecting body 510 and the lead-out piece 520 can be independently formed according to their own assembly and connection requirements. Thus, the connecting body 510 is indirectly connected to the external circuit 2 through the lead-out piece 520. Therefore, the connecting body 510 does not need to undergo large-area cutting and complex protrusion forming for connecting to the external circuit 2, which simplifies the processing technology of the lead-out piece 500, reduces waste of precious metals such as copper in the connecting body 510, and lowers costs. Furthermore, the lead-out piece 520 can be precision stamped separately on small-sized materials, resulting in higher material utilization. Simultaneously, since the lead-out piece 520 is specifically responsible for connecting to the external circuit 2, while the connecting body 510 only needs to focus on carrying the main circuit current, the complete large-section conductive path of the connecting body 510 can be maintained, avoiding damage to the integrity of the connecting body 510 due to the connection requirements of the external circuit 2, and ensuring the current-carrying capacity and mechanical strength of the connecting body 510.

[0060] Optionally, see Figures 2 to 5As shown, in some embodiments, the lead-out segment 522 is provided with a lead-out protrusion 5221. For example, the lead-out protrusion 5221 can be a protrusion structure integrally formed with the lead-out segment 522. The lead-out segment 522 is configured to be riveted to the external line 2 through the lead-out protrusion 5221. For example, the end of the external line 2 can be set as a ring structure, and the ring structure is sleeved on the lead-out protrusion 5221 of the lead-out segment 522. The connection and fixation between the lead-out segment 522 and the external line 2, as well as the conduction of electricity, are achieved by riveting.

[0061] In other embodiments, the lead-out section 522 is provided with a lead-out through hole, for example, the lead-out through hole can penetrate the lead-out section 522. The lead-out section 522 is configured to be riveted to the external line 2 through the lead-out through hole. For example, the end of the external line 2 can be set as a strip structure, and the strip structure can be inserted into the lead-out through hole of the lead-out section 522. The connection and fixation between the lead-out section 522 and the external line 2 and the conductivity are achieved by riveting.

[0062] Therefore, by setting lead-out protrusions 5221 or lead-out through holes in lead-out section 522, lead-out section 522 can be electrically connected to external line 2 by riveting, which can ensure the connection strength between lead-out section 522 and external line 2 and ensure stable contact and conductivity.

[0063] In other embodiments, the external line 2 is plugged into the lead-out section 522. For example, the interface end of the external line 2 is provided with a socket structure. The socket structure is elastic, and after the lead-out section 522 is inserted into the socket structure, it is firmly connected under the action of elasticity and can transmit signals. Thus, the lead-out piece 500 can electrically connect the contact assembly 10 and the external line 2 for signal transmission. As provided in this embodiment, the lead-out piece 520 is set independently of the connection body 510, which can further reduce consumables and lower costs.

[0064] Optionally, see Figures 2 to 3 As shown, in some embodiments, the fixing segment 521 is riveted to the connecting body 510, so that the fixing segment 521 and the connecting body 510 are directly connected, fixed and conductive, without the need for additional conductive connectors. This helps to simplify the overall structure of the lead-out piece 500, reduce the molding difficulty of the lead-out piece 500, and at the same time ensure the stability of the structure of the lead-out piece 500 after riveting.

[0065] Further, see Figures 2 to 3As shown, in some embodiments, the fixing segment 521 is provided with a connecting through hole 5211, which penetrates the fixing segment 521. The connecting body 510 is provided with a connecting protrusion 511, which is a protruding structure integrally formed with the connecting body 510. The shape and size of the connecting protrusion 511 are adapted to the connecting through hole 5211, so that the connecting protrusion 511 can extend into the connecting through hole 5211. During assembly, the fixing segment 521 is riveted to the connecting body 510 through the connecting through hole 5211 and the connecting protrusion 511. Specifically, the connecting protrusion 511 of the connecting body 510 is passed through the connecting through hole 5211 of the fixing segment 521, and then the connecting protrusion 511 is pressed and riveted, so that the connecting protrusion 511 deforms and fits tightly against the edge of the connecting through hole 5211, thereby realizing the riveting fixation of the fixing segment 521 and the connecting body 510. Therefore, by riveting the connecting protrusion 511 with the connecting through hole 5211, the relative positions of the fixed section 521 and the connecting body 510 can be accurately ensured during assembly, improving assembly efficiency. It also makes the contact area between the fixed section 521 and the connecting body 510 larger and the contact tighter, effectively reducing contact resistance and ensuring the stability of current transmission.

[0066] It is understood that the positions of the connecting through hole 5211 and the connecting protrusion 511 are not limited to the above-described arrangement. For example, in some other embodiments, the fixing segment 521 is provided with a connecting protrusion, which is configured as a protruding structure integrally formed with the fixing segment 521. The connecting body 510 is provided with a connecting through hole, which penetrates the connecting body 510. During assembly, the fixing segment 521 is riveted to the connecting body 510 through the connecting protrusion and the connecting through hole. Specifically, the connecting protrusion of the fixing segment 521 is passed through the connecting through hole of the connecting body 510, and then the connecting protrusion is press-riveted, so that the connecting protrusion deforms and fits tightly against the edge of the connecting through hole. At this time, precise riveting and stable conductivity between the fixing segment 521 and the connecting body 510 can also be achieved.

[0067] Further, see Figures 2 to 3 As shown, in some embodiments, the fixed section 521 and the lead-out section 522 are arranged sequentially along a first direction, which is X1 in the figure. Thus, the lead-out member 520 extends as a whole along the first direction, so that the lead-out section 522 of the lead-out member 520 extends outward along the first direction to the outside of the housing 20 of the relay 1, which can both meet the connection with the external line 2 and reduce the space occupied by the lead-out member 520 inside the housing 20.

[0068] There are multiple connecting protrusions 511, which are arranged at intervals along the first direction, meaning there is a gap between adjacent connecting protrusions 511. For example, all connecting protrusions 511 can be arranged in a row, meaning all connecting protrusions 511 are arranged along the same straight line parallel to the first direction. Alternatively, all connecting protrusions 511 can be arranged in multiple rows, meaning all connecting protrusions 511 are arranged along multiple straight lines parallel to the first direction. Furthermore, there are multiple connecting through holes 5211, for example, the number of connecting through holes 5211 can be the same as the number of connecting protrusions 511. The multiple connecting through holes 5211 and the multiple connecting protrusions 511 correspond one-to-one, and the fixing segment 521 is riveted to the connecting body 510 through the multiple connecting through holes 5211 and the multiple connecting protrusions 511. Therefore, the fixed section 521 and the connecting body 510 are riveted at multiple points through multiple connecting through holes 5211 and multiple connecting protrusions 511, which helps to improve the connection strength and structural stability between the fixed section 521 and the connecting body 510. At the same time, it increases the contact area between the fixed section 521 and the connecting body 510, further reduces the contact resistance, and improves the efficiency and stability of current transmission.

[0069] Optionally, see Figures 4 to 5 As shown, in some embodiments, the fixing segment 521 is plugged into the connecting body 510. During assembly, the fixing segment 521 and the connecting body 510 are directly plugged in to form the lead-out piece 500. This assembly operation is convenient and ensures sufficient contact area between the fixing segment 521 and the connecting body 510, guaranteeing good conductivity. Furthermore, because the plug-in connection is detachable, if the external line 2 fails, maintenance personnel only need to remove the old lead-out piece 520 and the damaged external line 2 from the connecting body 510 and replace them with new ones. The entire process requires no secondary processing of the connecting body 510, making it fast and safe, achieving low-cost and high-efficiency on-site maintenance.

[0070] Further, see Figures 4 to 5As shown, in some embodiments, the fixing segment 521 is recessed with a connecting groove 5212. For example, elastic sheets extend from both sides of the fixing segment 521 to form the connecting groove 5212, which can be a square groove or the like. The connecting body 510 is provided with a connecting protrusion 512, which protrudes from the surface of the connecting body 510 or is formed by a partial structure of the edge of the connecting body 510. For example, the connecting protrusion 512 can be a square protrusion structure integrally formed with the connecting body 510. The shape of the connecting protrusion 512 is adapted to the connecting groove 5212, so that the connecting protrusion 512 can be inserted into the connecting groove 5212, realizing an elastic connection between the fixing segment 521 and the connecting body 510. For example, the connecting protrusion 512 can be interference-fitted with the connecting groove 5212. Therefore, during assembly, the connecting protrusion 512 of the connecting body 510 is directly inserted into the connecting groove 5212 of the fixed section 521, so that the fixed section 521 and the connecting body 510 are stably connected under the action of elastic force, and signal transmission can be performed, thereby realizing the plug-in fit between the fixed section 521 and the connecting body 510. In this embodiment, the connecting protrusion 512 and the connecting groove 5212 can provide a positioning reference for plug-in assembly, which is beneficial to improving the assembly accuracy and efficiency of the fixed section 521 and the connecting body 510. Furthermore, the plug-in fit of the connecting protrusion 512 and the connecting groove 5212 increases the contact area between the fixed section 521 and the connecting body 510, which can effectively reduce contact resistance and ensure conductivity stability.

[0071] It is understood that the positions of the connecting through hole 5211 and the connecting protrusion 511 are not limited to the above-described arrangement. For example, in some other embodiments, the fixing segment 521 is provided with a connecting protrusion, and the connecting body 510 is provided with a connecting groove that matches the connecting protrusion. The fixing segment 521 is inserted into the connecting groove of the connecting body 510 through the connecting protrusion, which can also achieve precise insertion and stable electrical connection between the fixing segment 521 and the connecting body 510.

[0072] Further, see Figures 4 to 5As shown, in some embodiments, the lead-out member 520 further includes a connecting segment 523, which connects the lead-out segment 522 and the fixed segment 521. The fixed segment 521 is disposed inside the housing 20 of the relay 1, and the lead-out segment 522 is disposed outside the housing 20 of the relay 1. Part of the structure of the connecting segment 523 is located inside the housing 20 of the relay 1 and is connected to the fixed segment 521 inside the housing 20. Another part of the connecting segment 523 is located outside the housing 20 of the relay 1 and is connected to the lead-out segment 522 outside the housing 20. In this embodiment, only the connecting segment 523 passes through the housing 20 of the relay 1. Therefore, it is only necessary to specifically set the size and shape of the connecting segment 523 to adapt to the structural requirements of the housing 20, without having to adapt the shapes of the fixed segment 521 and the lead-out segment 522, which helps to reduce the manufacturing difficulty of the lead-out member 520. Meanwhile, since the lead-out section 522 is located outside the housing 20, the extension direction of the lead-out section 522 is more flexible, and the angle and position can be adjusted according to the connection requirements of the external line 2, further improving the adaptability of the lead-out piece 500.

[0073] Further, see Figures 4 to 5 As shown, in some embodiments, the fixed section 521, the connecting section 523, and the lead-out section 522 are arranged sequentially along a first direction, which is X1 in the figures. That is, the lead-out member 520 extends entirely along the first direction to reduce the space occupied by the lead-out member 520 inside the relay 1 and to fit the compact layout inside the housing 20.

[0074] Furthermore, the second direction is defined as a direction perpendicular to both the first direction and the thickness direction of the lead-out piece 500; in the attached figures, the second direction is the X2 direction. In the second direction, the dimension of the connecting segment 523 is less than or equal to the dimension of the fixed segment 521, and also less than or equal to the dimension of the lead-out segment 522. The smaller dimension of the connecting segment 523 along the second direction avoids interference between the connecting segment 523 and other components, facilitates the passage of the connecting segment 523 through the housing 20, improves assembly convenience, and also helps save on the consumable material of the lead-out piece 520, further reducing production costs.

[0075] Further, see Figures 4 to 5 As shown, in some embodiments, the fixing section 521, the connecting section 523, and the lead-out section 522 are integrally formed, making the overall structure and conductivity of the lead-out member 520 more stable.

[0076] Furthermore, in some embodiments, the moving contact 210 and the connecting body 510 of the lead-out piece 500 are riveted together by multiple rows of second protrusions 513, which are spaced apart along the length of the moving contact 210. For example, see [reference needed]. Figure 1As shown, the connecting body 510 of the lead-out piece 500 has two rows of second protrusions 513. The two rows of second protrusions 513 are spaced apart along the length direction of the moving contact 210, where the length direction of the moving contact 210 is the left-right direction in the figure. Each row of second protrusions 513 includes several second protrusions 513 protruding from the surface of the connecting body 510. During assembly, the moving contact 210 is riveted to the lead-out piece 500 through the second protrusions 513, which not only ensures a stable connection but also reduces the current carrying capacity per unit of riveting, thereby reducing the temperature rise. Of course, in other optional embodiments, the connecting body 510 of the lead-out piece 500 can also be provided with three, four, or more rows of second protrusions 513, and the second protrusions 513 can also be provided on the moving contact 210, in which case riveting fixation can be achieved.

[0077] Continue reading Figure 1 , Figure 6 and Figure 7 As shown, the contact assembly 10 includes a stationary contact unit 100, a moving contact unit 200, and an isolator 300.

[0078] The stationary contact unit 100 includes a stationary contact 110 and a stationary magnetic conductor 120. The stationary contact 110 is used to connect to an external load circuit. The stationary contact 110 has a stationary contact 130 that remains stationary, located on the side of the stationary contact 110 closer to the moving contact 210. The stationary contact 130 is used to make contact with the moving contact 230 to conduct electricity. The stationary magnetic conductor 120 is connected to the stationary contact 110. For example, the stationary magnetic conductor 120 can be connected and fixed to the stationary contact 110 by riveting, bonding, welding, snap-fitting, etc. The stationary magnetic conductor 120 is used to cooperate with the moving magnetic conductor 220 through magnetic attraction to ensure stable contact between the stationary contact 130 and the moving contact 230.

[0079] The moving contact unit 200 includes a moving contact 210 and a moving magnetic conductor 220. The moving contact 210 is used to connect to an external load circuit. Exemplarily, the moving contact 210 can be a resilient metal spring structure. One end of the moving contact 210 is fixed relative to the stationary contact 110, for example, it can be riveted and fixed inside the relay 1, remaining relatively stationary with respect to the stationary contact 110. The other end of the moving contact 210 can swing relative to the stationary contact 110, for example, it can move closer to or away from the stationary contact 110 under external force, where the external force can be an electromagnetic force or a mechanical force. The other end of the moving contact 210 has a moving contact 230, which can be a hemispherical or frustum-shaped protrusion with a higher conductivity than the moving contact 210. When the other end of the moving contact 210 swings, it causes the moving contact 230 to contact and conduct or separate from the stationary contact 130 on the stationary contact 110, thereby realizing the on / off control of the relay 1. The moving magnetic conductor 220 is connected to the moving contact 210. For example, the moving magnetic conductor 220 can be connected and fixed to the moving contact 210 by riveting, bonding, welding, snap-fitting, etc. The moving magnetic conductor 220 is used to cooperate with the stationary magnetic conductor 120 through magnetic attraction. The moving magnetic conductor 220 and the stationary magnetic conductor 120 are arranged opposite to each other, and an independent short-circuit ring can be formed between the moving magnetic conductor 220 and the stationary magnetic conductor 120. The magnetic interaction between the moving magnetic conductor 220 and the stationary magnetic conductor 120 can apply a force to the moving contact 210 to move it closer to the stationary contact 110, thereby maintaining stable contact between the moving contact 230 and the stationary contact 130 when the relay 1 is closed.

[0080] An isolator 300 is disposed between the moving magnetic conductor 220 and the stationary magnetic conductor 120, and the isolator 300 is configured to prevent the moving magnetic conductor 220 and the stationary magnetic conductor 120 from contacting each other.

[0081] It is understandable that if the magnetic attraction between the moving magnet 220 and the stationary magnet 120 is too large, for example, if a short circuit or other fault causes an increase in circuit current, resulting in an excessive magnetic attraction between the moving magnet 220 and the stationary magnet 120, the moving magnet 220 will exert an excessive force on the moving contact 210 toward the stationary contact 110. This can easily cause the moving contact 210 to deform, affecting its working condition and service life.

[0082] In this embodiment, through the above-described structural design, the isolator 300 is positioned between the moving magnetic material 220 and the stationary magnetic material 120, preventing them from directly contacting each other when the magnetic attraction force is excessive. On one hand, the isolator 300's blocking and limiting effect maintains a preset gap between the moving magnetic material 220 and the stationary magnetic material 120, preventing them from becoming too close together and causing excessive deformation of the moving contact 210, thus improving the reliability and service life of the relay 1. On the other hand, the isolator 300 reliably separates the moving magnetic material 220 from the stationary magnetic material 120, preventing direct contact that could cause a magnetic short circuit or magnetic shunting, thereby ensuring stable magnetic flux, maintaining stable magnetic attraction force, and ensuring stable and reliable contact between the moving contact 230 and the stationary contact 130.

[0083] Optionally, in some embodiments, the isolator 300 is made of an insulating material. Specifically, the isolator 300 disposed between the moving magnetic conductor 220 and the stationary magnetic conductor 120 is made of an insulating material, such as plastic, ceramic, insulating rubber, etc. In this embodiment, the isolator 300 made of an insulating material can effectively prevent excessive deformation of the moving contact 210, and can also effectively prevent the formation of additional conductive paths between the moving magnetic conductor 220 and the stationary magnetic conductor 120 due to contact, preventing unnecessary conductive losses, ensuring the accuracy of circuit conduction, and ensuring stable contact between the moving contact 230 and the stationary contact 130.

[0084] Furthermore, in some embodiments, the isolator 300 has a gap between itself and at least one of the stationary magnet 120 and the moving magnet 220, which can be used to adjust the magnetic attraction between the moving magnet 220 and the stationary magnet 120.

[0085] For example, see Figure 1 and Figure 7 , Figures 12 to 13As shown, the isolator 300 is disposed between the moving magnetic body 220 and the stationary magnetic body 120, with a pre-existing gap H between them. In practical applications, the size of the gap H can be preset according to the magnitude of the current in the relay 1 circuit. Due to the gap H, when a change in current causes a change in the magnetic attraction between the moving magnetic body 220 and the stationary magnetic body 120, the moving magnetic body 220 can cause the moving contact 210 to move adaptively relative to the stationary contact 110. The gap H decreases or increases accordingly with the displacement of the moving magnetic body 220. Specifically, when the magnetic attraction increases, the moving magnetic body 220 moves closer to the stationary magnetic body 120, the gap H decreases, and the moving contact 210 and the stationary contact 110 become closer; when the magnetic attraction decreases, the moving magnetic body 220 moves away from the stationary magnetic body 120, the gap H increases, and the moving contact 210 moves further away from the stationary contact 110. Therefore, by reserving a gap H between the isolator 300 and the moving magnetic conductor 220, a buffer space can be provided for the movement of the moving contact 210 under magnetic attraction, avoiding excessive deformation or stress concentration of the moving contact 210 due to excessive force, ensuring the stable operation of the magnetic circuit between the moving magnetic conductor 220 and the stationary magnetic conductor 120, thereby improving the contact stability and conduction reliability of the moving contact 210 and the stationary contact 110.

[0086] It is understood that in other alternative embodiments, there may be a gap between the isolator 300 and the stationary magnet 120, or there may be gaps between the isolator 300 and the stationary magnet 120 and the moving magnet 220 respectively. The above structures can provide buffer space for the movement of the moving magnet 220, avoid rigid interference of the structure, and ensure that the relay 1 works stably and reliably.

[0087] Further, see Figures 6 to 7 As shown, in some embodiments, the relay 1 includes a housing 20 and a fixing member 30. The fixing member 30 is connected to the housing 20, and the isolator 300 of the contact assembly 10 is connected to the fixing member 30. The isolator 300 is configured to be fixed between the stationary magnetic body 120 and the moving magnetic body 220 via the fixing member 30. For example, the fixing member 30 can be directly connected to the housing 20 of the relay 1, or connected to other fixed components inside the housing 20, as long as it can stably support the isolator 300. Specifically, in this embodiment, the isolator 300 is connected to the housing 20 of the relay 1 via the fixing member 30. For example, the fixing member 30 and the housing 20 can be connected by welding, bonding, or integral molding. The isolator 300 is connected to the fixing member 30, for example, the isolator 300 and the fixing member 30 can be integrally molded or connected by welding, bonding, etc., so that the isolator 300 is disposed between the moving magnetic body 220 and the stationary magnetic body 120.

[0088] Therefore, by fixing the isolator 300 with the fixing member 30, the installation position of the isolator 300 is not affected by the movement position of the moving magnetic body 220, improving the positioning accuracy of the isolator 300 and ensuring that the isolator 300 can reliably prevent the moving magnetic body 220 from directly contacting the stationary magnetic body 120. Furthermore, the isolator 300 has a non-contact fit with both the moving magnetic body 220 and the stationary magnetic body 120, which allows for a pre-set gap between the isolator 300 and the moving magnetic body 220. This provides buffer space for the movement of the moving magnetic body 220 and the deformation of the moving contact 210, ensuring magnetic circuit stability and reliable magnetic attraction, and improving the operational stability of the relay 1.

[0089] Optionally, in other embodiments, the isolator 300 is connected to at least one of the stationary magnet 120 and the moving magnet 220. For example, the isolator 300 may be connected to the stationary magnet 120, and there is a gap between the isolator 300 and the moving magnet 220. Alternatively, the isolator 300 may also be connected to the moving magnet 220, and there is a gap between the isolator 300 and the stationary magnet 120. Furthermore, the isolator 300 may be connected to both the stationary magnet 120 and the moving magnet 220 simultaneously. In this embodiment, the isolator 300 is directly fixed to at least one of the stationary magnet 120 and the moving magnet 220, eliminating the need for other components to support the isolator 300. This simplifies the overall assembly of the contact assembly 10 and reduces assembly difficulty and manufacturing costs.

[0090] See Figure 7 , Figures 12 to 13 As shown, in some embodiments, the stationary contact 110 and the moving contact 210 are spaced apart along the thickness direction of the contact assembly 10. This spacing means that the stationary contact 110 and the moving contact 210 have a distance between them in the thickness direction of the contact assembly 10. Specifically, both the stationary contact 110 and the moving contact 210 have a generally sheet-like structure and are arranged in parallel. The thickness direction of the contact assembly 10 is the spacing direction between the stationary contact 110 and the moving contact 210, which is the Z-direction. An isolator 300 is disposed between the moving magnetic conductor 220 and the stationary magnetic conductor 120 along the thickness direction of the contact assembly 10, effectively preventing the moving magnetic conductor 220 and the stationary magnetic conductor 120 from contacting each other, thereby preventing the moving contact 210 from getting too close to the stationary contact 110 and causing excessive deformation.

[0091] Optionally, in some examples, the orthographic projection of at least one of the static magnet 120 and the moving magnet 220 along the thickness direction of the contact assembly 10 falls within the orthographic projection range of the isolator 300 along the thickness direction of the contact assembly 10. Specifically, in some embodiments, the orthographic projection of the isolator 300 along the thickness direction of the contact assembly 10 is a solid shape, for example, see [reference missing]. Figure 12 and Figure 14As shown, the isolator 300 is a solid flat plate. In this case, the orthographic projection of the isolator 300 along the thickness direction of the contact assembly 10 is a solid rectangle. This solid flat plate isolator 300 can uniformly block the contact between the moving magnetic material 220 and the stationary magnetic material 120. The orthographic projection of the moving magnetic material 220 along the thickness direction of the contact assembly 10 falls entirely within the orthographic projection range of the isolator 300 along the thickness direction of the contact assembly 10, allowing the isolator 300 to form a complete coverage of the moving magnetic material 220, thereby completely isolating the possibility of contact between the moving magnetic material 220 and the stationary magnetic material 120, resulting in a more thorough blocking effect. Of course, the orthographic projection of the stationary magnetic material 120 along the thickness direction of the contact assembly 10 can also fall entirely within the orthographic projection range of the isolator 300 along the thickness direction of the contact assembly 10 to further improve the blocking effect.

[0092] Optionally, in other examples, the orthographic projection of the stationary magnet 120 along the thickness direction of the contact assembly 10 and the orthographic projection of the isolator 300 along the thickness direction of the contact assembly 10 have a first region that does not coincide, meaning that the portion of the structure of the stationary magnet 120 corresponding to the first region is not obscured by the isolator 300. The orthographic projection of the moving magnet 220 along the thickness direction of the contact assembly 10 and the orthographic projection of the isolator 300 along the thickness direction of the contact assembly 10 have a second region that does not coincide, meaning that the portion of the structure of the moving magnet 220 corresponding to the second region is not obscured by the isolator 300. The first region and the second region partially or completely overlap, meaning there is an overlapping area between the first region and the second region, so that the stationary magnet 120 and the moving magnet 220 are not completely obscured by the isolator 300. For example, see [reference needed]. Figure 13 and Figure 15 As shown, the spacer 300 is a solid strip, and its orthographic projection along the thickness direction of the contact assembly 10 is a solid rectangle. There are two spacers 300, and the two strip-shaped spacers 300 form a hollow region, which constitutes at least a portion of the overlapping region of the first region and the second region. Within this hollow area, the isolator 300 does not obstruct the contact between the stationary magnet 120 and the moving magnet 220. At this time, the isolator 300 can still prevent the stationary magnet 120 and the moving magnet 220 from contacting each other. It can also reduce the material used in the isolator 300, reduce the production cost of the isolator 300, and at the same time minimize the influence of the isolator 300 on the magnetic field distribution between the stationary magnet 120 and the moving magnet 220. This is beneficial to ensuring the electromagnetic performance of the stationary magnet 120 and the moving magnet 220, and ensuring that the moving contact 230 and the stationary contact 130 can make stable and reliable contact under the magnetic attraction between the stationary magnet 120 and the moving magnet 220.

[0093] Of course, in some embodiments, the orthographic projection of the spacer 300 along the thickness direction of the contact assembly 10 can also be a perforated shape. For example, as Figure 16As shown, the spacer 300 is rectangular, and its orthographic projection along the thickness direction of the contact assembly 10 is a perforated square ring. For example, as... Figure 17 As shown, the isolator 300 is annular, and its orthographic projection along the thickness direction of the contact assembly 10 is a perforated annular ring. In this case, the isolator 300 only partially blocks the space between the stationary magnet 120 and the moving magnet 220, effectively ensuring the blocking effect while adapting to the production needs of relays 1 of different specifications. Simultaneously, it reduces raw material consumption and lowers manufacturing costs. This application, by providing an isolator 300 between the moving magnet 220 and the stationary magnet 120, effectively prevents direct contact between them, avoiding excessive deformation of the moving contact 210 due to excessive proximity to the stationary contact 110, and ensuring a stable and reliable contact structure. The isolator 300 can adopt various structural forms such as full-coverage flat plate, strip, square frame, and ring. It can effectively block the moving magnetic conductor 220 and the stationary magnetic conductor 120, reduce raw material consumption, and reduce production and manufacturing costs. At the same time, it can reduce the impact on the magnetic field distribution, ensure the stability of magnetic attraction, and make the contact between the moving contact 230 and the stationary contact 130 more reliable, which is conducive to improving the overall working stability and service life of the relay 1.

[0094] Optionally, in some embodiments, the stationary contact 110 has a split structure, including a connecting portion 111 and an electrical lead-out portion 112, with the electrical lead-out portion 112 used for current conduction. One end of the electrical lead-out portion 112 has a stationary contact 130, and the connecting portion 111 is connected to the electrical lead-out portion 112. The connecting portion 111 is located on the side of the stationary contact 130 away from the electrical lead-out portion 112, so that when the stationary contact 130 is electrically connected to the moving contact 230, the structure between the corresponding electrical lead-out portion 112 and the stationary contact 130 of the stationary contact 110 serves as the energized portion of the stationary contact 110, and the connecting portion 111 is the non-energized portion of the stationary contact 110. Furthermore, the stationary magnetic conductor 120 can be selectively connected to a preset position of the connecting portion 111 or directly connected to the non-contact area of ​​the electrical lead-out portion 112. For example, see... Figures 6 to 10 As shown, the stationary magnet 120 is connected to the connecting part 111, meaning the stationary magnet 120 is fixed to the non-energized portion of the stationary contact 110, thus separating the stationary magnet 120 from the electrical lead-out part 112. This helps reduce the impact of the stationary magnet 120 on the current conduction of the electrical lead-out part 112. Therefore, the split-type stationary contact 110 allows for the separate design of the connecting part 111 and the electrical lead-out part 112 based on different functional requirements for connection and conduction, thereby improving the overall performance of the stationary contact 110 and facilitating adaptation to different relay 1 structural layouts.

[0095] Optionally, see Figure 11As shown, in some embodiments, the stationary contact 110 is a one-piece structure, with a stationary contact 130 at one end and a stationary magnet 120 disposed between the other end of the stationary contact 110 and the stationary contact 130. This one-piece stationary contact 110 has a simpler structure, fewer processing steps, lower assembly difficulty, and higher structural stability. Furthermore, the cooperation between the stationary magnet 120 and the moving magnet 220 effectively ensures the working stability of the contact assembly 10.

[0096] Furthermore, in some embodiments, the connecting portion 111 is provided with a hollowed-out groove 1111. For example, see [reference needed]. Figure 9 As shown, the connecting part 111 is provided with a through slot 1111, which helps to reduce the weight of the connecting part 111 and the amount of material used in the connecting part 111, thereby reducing the cost. At the same time, the static magnetic conductor 120 is connected to the connecting part 111 and covers the through slot 1111, thereby making full use of the space in the area where the connecting part 111 is located, making the static contact unit 100 structure more compact.

[0097] Furthermore, see Figures 8 to 10 As shown, the connecting part 111 and the electrical lead-out part 112 are directly riveted together through the stationary contact 130 without the need for additional connecting structures, which makes the processing technology of the stationary contact 110 simpler and the cost lower.

[0098] Furthermore, see Figures 8 to 10 As shown, the stationary magnet 120 is provided with a plurality of first protrusions 121. The stationary magnet 120 is riveted to the connecting part 111 through the first protrusions 121 to ensure a stable connection. It can be understood that in other optional embodiments, the first protrusions 121 can also be provided on the connecting part 111, in which case the stationary magnet 120 and the connecting part 111 can also be riveted together through the first protrusions 121.

[0099] Furthermore, see Figures 1 to 6 , Figures 8 to 10As shown, a stationary magnet 120 is connected to a connecting portion 111. A first fixing protrusion 1112 is provided on the side of the connecting portion 111 away from the stationary magnet 120. A first fixing groove 21 is provided in the housing 20 to mate with the first fixing protrusion 1112. A second fixing protrusion 1113 is provided at the end of the connecting portion 111 away from the electrical lead-out portion 112. A second fixing groove 22 is provided in the housing 20 to mate with the second fixing protrusion 1113. There are two of each of the first fixing protrusion 1112 and the second fixing protrusion 1113. Of course, in other embodiments, the number of the first fixing protrusion 1112 and the second fixing protrusion 1113 may also be one, two, three, etc. When the contact component 10 is assembled on the relay 1, the first fixing protrusion 1112 and the second fixing protrusion 1113 can be connected to other components of the relay 1. For example, in this embodiment, the first fixing protrusion 1112 and the second fixing protrusion 1113 are respectively engaged with the first fixing groove 21 and the second fixing groove 22 of the housing 20 of the relay 1, thereby effectively ensuring the assembly stability of the contact component 10.

[0100] Furthermore, in some embodiments, the conductivity of the connecting portion 111 is lower than that of the electrical lead-out portion 112. Specifically, the electrical lead-out portion 112 can be made of a high-conductivity material, such as copper, to ensure current conduction efficiency, reduce the conductive loss of the stationary contact 110, and improve the overall conductivity of the contact assembly 10. Moreover, the connecting portion 111 can be made of a low-conductivity material, such as iron, to ensure structural rigidity, which is beneficial for effectively connecting and supporting the stationary magnet 120. At the same time, the iron connecting portion 111 is less expensive, thus reducing costs.

[0101] Furthermore, in some embodiments, the stationary magnet 120 and the connecting portion 111 are made of the same material. This effectively reduces problems such as inconsistent deformation and loose connections caused by material differences, which is beneficial to improving the stability of the connection between the stationary magnet 120 and the connecting portion 111 and the overall stability of the contact assembly 10. At the same time, since the stationary magnet 120 and the connecting portion 111 are made of the same material, the connecting portion 111 can play a magnetic guiding role, which helps to reduce the thickness of the stationary magnet 120, reduce material consumption, and reduce costs.

[0102] Furthermore, in some embodiments, the electrical lead-out portion 112 is made of a high-conductivity material such as copper, while the static magnet 120 and the connecting portion 111 are made of at least one of low-conductivity materials such as iron, cobalt, and nickel. This ensures both the magnetic conductivity of the static magnet 120 and the connecting portion 111, meeting the electromagnetic performance requirements of both the static magnet 120 and the moving magnet 220, and also guarantees the structural support capacity of the connecting portion 111.

[0103] Optionally, in some embodiments, the moving contact 210 includes multiple stacked compression springs. The multiple stacked compression springs are tightly fitted together, and the number of stacked compression springs can be selected according to the conductivity requirements of the contact assembly 10. In this embodiment, the moving contact 210 uses multiple stacked compression springs, which can improve the structural strength of the moving contact 210, further ensuring the contact conductivity between the moving contact 230 and the stationary contact 130. At the same time, without increasing the thickness of the compression springs, replacing a single thick spring with multiple thin compression springs can reduce the reaction force while ensuring the overall structural strength, reduce the deformation stress of the moving contact 210, and make the operation more flexible and the service life longer.

[0104] In summary, the lead-out piece 500, contact assembly 10, and relay 1 of the embodiments of this application have at least the following advantages and beneficial effects:

[0105] The relay 1 in this embodiment includes a contact assembly 10, which includes a lead-out piece 500. The lead-out piece 500 includes a separate connecting body 510 and a lead-out component 520. The connecting body 510 and the lead-out component 520 can be independently formed according to their own assembly and connection requirements, thereby reducing the overall forming difficulty of the lead-out piece 500 and reducing the waste generated when cutting raw materials to manufacture the lead-out piece 500, thus reducing raw material consumption and production costs. At the same time, the connecting body 510 is indirectly connected to the external circuit 2 through the lead-out component 520. Therefore, the connecting body 510 does not need to be cut into large areas and complexly formed for connecting the external circuit 2, which helps to simplify the processing technology of the lead-out piece 500, reduce the waste of precious metal copper and other raw materials of the connecting body 510, and reduce costs. Furthermore, since the lead-out piece 520 is specifically responsible for connecting to the external line 2, while the connecting body 510 only needs to focus on carrying the main circuit current, the complete large-section conductive path of the connecting body 510 can be maintained. This avoids damage to the integrity of the connecting body 510 due to the connection requirements of the external line 2, ensuring the current carrying capacity and mechanical strength of the connecting body 510. In addition, the split-type lead-out piece 500 makes the current lead-out structure layout more flexible. The shape of the lead-out piece 500 can be flexibly set according to the internal space requirements of the relay 1 and the connection requirements of the external line 2, resulting in stronger adaptability. By using the lead-out piece 500, the relay 1 and the contact assembly 10 can reduce manufacturing difficulty, reduce waste, and lower production costs.

[0106] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0107] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
