[0002] This application belongs to the field of control switch technology, specifically relating to a relay. Background Technology

[0003] In the electrical engineering industry, relays are widely used as control devices. They have a control system (also known as an input circuit) and a controlled system (also known as an output circuit), and are typically used in automatic control circuits. A relay is essentially 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.

[0004] In existing high-voltage DC relays, when it is necessary to achieve automatic switching control of multiple circuits, relays need to be arranged in the corresponding circuits, which increases the cost of using relays and requires installation and connection in multiple locations, which also increases the difficulty of relay installation layout.

[0080] The relays provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0081] Referring to Figures 1 to 4, a schematic diagram of the structure of a relay according to an embodiment of this application is shown. The relay includes:

[0082] At least two push components 10;

[0083] A stationary contact assembly 11, the stationary contact assembly 11 including at least four stationary contact leads 111;

[0084] At least two moving contact assemblies 12, each of the moving contact assemblies 12 being connected to a push assembly 10, the push assembly 10 driving the corresponding moving contact assembly 12 to move relative to the stationary contact assembly 11;

[0085] When a portion of the moving contact assembly 12 moves to be in contact with the stationary contact assembly 11, at least four of the stationary contact lead-out ends 111 form multiple independent paths;

[0086] When the moving contact assembly 12 in another part moves to be in contact with the stationary contact assembly 11, at least four of the stationary contact leads 111 form at least one path.

[0087] Figure 1 shows an exploded view of the structure of a relay according to an embodiment of this application. In Figure 1, the push assembly 10, the stationary contact assembly 11, and the moving contact assembly 12 (see Figure 2) are assembled together to form the relay's on / off system. The push assembly 10 can be driven by the driving force output by the drive system 2, thereby causing the moving contact assembly 12 to move relative to the stationary contact assembly 11, thus realizing the on / off control of the relay. It should be noted that the driving force output by the drive system 2 can be an electromagnetic force directly generated by the principle of electromagnetic induction or a force generated by mechanical motion. For example, the electromagnetic force can be the electromagnetic force generated by a coil, and the force generated by mechanical motion can be the force generated by a device that converts electrical energy into mechanical energy. This application embodiment does not limit the structure of the drive system 2 or the type of driving force. It is easy to understand that when the push assembly 10 drives the moving contact assembly 12 to contact the stationary contact assembly 11, the relay is in a conducting state; when the push assembly 10 drives the moving contact assembly 12 to separate from the stationary contact assembly 11, the relay is in a disconnected state. The actuating component 10, the stationary contact component 11, and the moving contact component 12 can all be installed inside the plastic housing 30, which protects these components. Of course, the plastic housing 30 also serves as a support or bracket structure for mounting and fixing these components.

[0088] The stationary contact assembly 11 in this embodiment can be a metal contact structure that remains relatively stationary and fixed to the plastic housing 30. Specifically, it can include at least four stationary contact leads 111 spaced apart. The stationary contact leads 111 are terminals for connecting the load. When the moving contact assembly 12 is not in contact with the stationary contact leads 111, at least four stationary contact leads 111 are mutually insulated and disconnected. Thus, when two stationary contact leads 111 in the same load circuit are connected to the moving contact assembly 12, the load circuit is connected.

[0089] The number of moving contact assemblies 12 is the same as the number of pushing assemblies 10, both being no less than two. Each moving contact assembly 12 is connected to one pushing assembly 10. When the pushing assembly 10 is driven by the driving system 2, the pushing assembly 10 correspondingly drives the moving contact assembly 12 to move, causing the moving contact assembly 12 to move closer to or further away from the stationary contact assembly 11. In this embodiment, each pushing assembly 10 can be driven and controlled independently, and therefore, each moving contact assembly 12 can move independently without being affected by each other. When different numbers of moving contact assemblies 12 move to contact the stationary contact lead-out terminal 111, different operating states or operating modes of the relay can be formed.

[0090] Furthermore, it should be noted that in some embodiments, the drive system 2 can be controlled to drive only one of the two drive components 10 within the same time period, so that the relay has only multiple paths or at least one path within the current time period. This achieves interlocking of the two drive components 10 by the drive system 2, avoiding malfunctions that could damage the relay and the load circuit.

[0091] When a portion of the moving contact assembly 12 is driven by the corresponding pushing assembly 10 to connect with the stationary contact assembly 11, at least four stationary contact leads 111 can form multiple independent paths. At this time, each independent path can control a load device. Under this condition, multiple load devices or multiple load circuits can be controlled by a single relay.

[0092] When another portion of the moving contact assembly 12 is driven by the corresponding pushing assembly 10 to connect with the stationary contact assembly 11, at least four stationary contact leads 111 can form at least one path. In this case, each independent path can control a load device. Thus, a single relay can control a load circuit. It is understood that in this situation, when more than two paths are formed, the paths can be electrically connected or independently disconnected, depending on whether the corresponding moving contact assembly 12 connects each path. This embodiment does not limit this.

[0093] It should be noted that the moving contact assembly 12 that forms multiple independent paths at the stationary contact lead-out end 111 and the moving contact assembly 12 that forms at least one path at the stationary contact lead-out end 111 may be duplicates or completely different.

[0094] Figure 2 shows an exploded view of a switching system according to an embodiment of this application. The relay shown in Figure 2 has four stationary contact leads 111. When the push assembly 10 moves upward along the Z direction as shown in the figure until it contacts the moving contact assembly 12, the four stationary contact leads 111 can form two independent paths. When the push assembly 10 moves upward along the Z direction as shown in the figure until it contacts the moving contact assembly 12, the four stationary contact leads 111 can form one path.

[0095] Furthermore, Figure 3 shows a schematic diagram of the six stationary contact leads 111 forming three independent paths, namely the three paths formed by the first stationary contact lead 111a and the sixth stationary contact lead 111f, the second stationary contact lead 111b and the fifth stationary contact lead 111e, and the third stationary contact lead 111c and the fourth stationary contact lead 111d. Figure 4 also shows a schematic diagram of the six stationary contact leads 111 forming one path, which can be the path between the fourth stationary contact lead 111d and the sixth stationary contact lead 111f. When the other two stationary contact leads 111 are conductive, a path is formed between the corresponding two stationary contact leads 111.

[0096] Therefore, in the relay of this application embodiment, the stationary contact assembly 11 includes at least four stationary contact leads 111, and there can be at least two pushing components 10 and two moving contact assemblies 12, with the moving contact assembly 12 being driven to move by the corresponding pushing component 10. When different numbers of pushing components 10 move, they can drive the same number of moving contact assemblies 12 connected to them to move. When the moving contact assemblies 12 are in different positions and different numbers are connected to the stationary contact assembly 11, multiple independent paths or a single path can be formed respectively. When multiple independent paths are formed, control of multiple load devices or multiple load circuits can be realized. Therefore, the relay of this application embodiment can realize the switching of different working modes, which helps to reduce the cost of using the relay and reduce the complexity of the installation layout.

[0097] Optionally, referring to Figures 3 to 10, when a portion of the moving contact assembly 12 moves to be in contact with the stationary contact assembly 11, at least two of the four stationary contact leads 111 are simultaneously connected to form multiple independent paths, wherein each of the stationary contact leads 111 is located in one path.

[0098] When the other part of the moving contact assembly 12 moves to be in contact with the stationary contact assembly 11, one of the at least four stationary contact leads 111 is in contact with one of the remaining stationary contact leads 111 to form a path.

[0099] Specifically, as shown in Figure 5, in one embodiment, when there are four stationary contact leads 111, they may include a first stationary contact lead 111a, a second stationary contact lead 111b, a third stationary contact lead 111c, and a fourth stationary contact lead 111d. There may be two moving contact assemblies 12.

[0100] As illustrated in Figures 7 and 8, when one moving contact assembly 12 moves to be in contact with the stationary contact assembly 11, the first stationary contact lead-out end 111a and the second stationary contact lead-out end 111b become connected to form a first path, and the third stationary contact lead-out end 111c and the fourth stationary contact lead-out end 111d become connected to form a second path. As illustrated in Figures 9 and 10, when another moving contact assembly 12 moves to be in contact with the stationary contact assembly 11, the second stationary contact lead-out end 111b and the third stationary contact lead-out end 111c become connected to form a path.

[0101] In one embodiment, when there are six stationary contact leads 111, they may specifically include a first stationary contact lead 111a, a second stationary contact lead 111b, a third stationary contact lead 111c, a fourth stationary contact lead 111d, a fifth stationary contact lead 111e, and a sixth stationary contact lead 111f. As shown in FIG3, when a moving contact assembly 12 (not shown in the figure) moves to be in contact with the stationary contact assembly 11, the first stationary contact lead 111a and the sixth stationary contact lead 111f are connected to form a first path, the second stationary contact lead 111b and the fifth stationary contact lead 111e are connected to form a second path, and the third stationary contact lead 111c and the fourth stationary contact lead 111d are connected to form a third path. As shown in Figure 4, when another moving contact assembly 12 (not shown in the figure) moves to be connected with the stationary contact assembly 11, the sixth stationary contact lead-out end 111f and the fourth stationary contact lead-out end 111d are connected to form a circuit.

[0102] When there are more stationary contact leads 111, the relays can form multiple independent paths or one path according to the above connection relationship. This application embodiment will not be described in detail here.

[0103] Optionally, when all the moving contact assemblies 12 move to separate from the stationary contact assemblies 11, all the stationary contact leads 111 disconnect from each other.

[0104] Specifically, in one embodiment, in the relay of this application, when each pushing component 10 drives the corresponding moving contact component 12 to separate from the stationary contact component 11, there are no two mutually conductive stationary contact leads 111 in the relay. In this case, the relay can maintain the cut-off working state and does not form any circuit.

[0105] Optionally, referring to FIG5, at least four stationary contact leads 111 include a first stationary contact lead 111a, a second stationary contact lead 111b, a third stationary contact lead 111c, and a fourth stationary contact lead 111d.

[0106] Specifically, in one embodiment, as illustrated in FIG5, when the number of stationary contact leads 111 in the relay of this application embodiment is four, it may specifically include a first stationary contact lead 111a, a second stationary contact lead 111b, a third stationary contact lead 111c, and a fourth stationary contact lead 111d. Based on the description of the foregoing embodiments, it is readily understood that a relay with this structure can operate with two independent paths, or switch to operating with one path, making it suitable for automated control scenarios that switch between two independent load circuits and a single load circuit. When used in two independent load circuits, the cost of using one relay can be saved.

[0107] Optionally, referring to FIG5, the first stationary contact lead-out end 111a, the second stationary contact lead-out end 111b, the third stationary contact lead-out end 111c, and the fourth stationary contact lead-out end 111d are arranged in a rectangular array, with the first stationary contact lead-out end 111a and the third stationary contact lead-out end 111c located on one diagonal of the rectangle, and the second stationary contact lead-out end 111b and the fourth stationary contact lead-out end 111d located on the other diagonal of the rectangle.

[0108] Specifically, in one embodiment, as illustrated in FIG5, in the relay of this application embodiment, when the number of stationary contact leads 111 is four, the first stationary contact lead 111a, the second stationary contact lead 111b, the third stationary contact lead 111c, and the fourth stationary contact lead 111d form a rectangular shape, each located at a right angle of the rectangle. The line connecting the first stationary contact lead 111a and the third stationary contact lead 111c forms a diagonal, and the line connecting the second stationary contact lead 111b and the fourth stationary contact lead 111d forms another diagonal. This arrangement of the stationary contact leads 111 helps improve the integration and compactness of the relay, and is beneficial for reducing the size and volume of the relay.

[0109] Optionally, referring to FIG5, the stationary contact assembly 11 further includes a first stationary contact support 112 and a second stationary contact support 113;

[0110] The first stationary contact bracket 112 is electrically connected to one of the four stationary contact leads 111;

[0111] The second stationary contact bracket 113 is electrically connected to another stationary contact lead-out 111 among the remaining stationary contact lead-outs 111;

[0112] Each of the moving contact assemblies 12 is located on the side of the first stationary contact support 112 and the second stationary contact support 113 away from the stationary contact lead-out end 111;

[0113] The pushing component 10 drives the corresponding moving contact component 12 to move to contact the first stationary contact bracket 112 and the second stationary contact bracket 113, so that the moving contact component 12 contacts and conducts with the stationary contact component 11.

[0114] Specifically, in one embodiment, as illustrated in Figure 5, taking the four stationary contact leads 111 as an example, the stationary contact assembly 11 in this embodiment of the relay further includes a first stationary contact bracket 112 and a second stationary contact bracket 113. Both stationary contact brackets are conductors, used to establish a conductive structure between the moving contact assembly 12 and the stationary contact assembly 11. The first stationary contact bracket 112 is electrically connected to one of the four stationary contact leads 111, and the second stationary contact bracket 113 is electrically connected to one of the remaining stationary contact leads 111. The two stationary contact brackets are arranged side by side with intervals. The moving contact assembly 12 can move linearly up and down below the two stationary contact brackets. It should be noted that the upper and lower positions in this embodiment of the application are referenced to the Z-direction of the movement of the pushing assembly 10. Along the Z-direction of the movement of the pushing assembly 10, the position closer to the stationary contact lead 111 is considered upper, and the position farther from the stationary contact lead 111 is considered lower. When the moving contact assembly 12 moves upward along the Z direction until it contacts the stationary contact assembly 11, it forms a closed circuit, and the load circuit of the relay is in a conducting state. When the moving contact assembly 12 moves downward along the Z direction until it separates from the stationary contact assembly 11, the load circuit of the relay is in a closed state.

[0115] Optionally, referring to FIG5, both the first stationary contact bracket 112 and the second stationary contact bracket 113 include a connecting portion 11a and an extension portion 11b;

[0116] The extension 11b is connected to one end of the connecting part 11a and extends in a direction away from the other end of the connecting part 11a.

[0117] Specifically, in one embodiment, the first stationary contact bracket 112 and the second stationary contact bracket 113 can be parts with the same structural shape made of metal parts through the same stamping process, which can reduce the processing steps of the stationary contact bracket and improve manufacturing efficiency.

[0118] As shown in Figure 5, any stationary contact bracket may include a connecting portion 11a and an extension portion 11b. The extension portion 11b is connected to one end of the connecting portion 11a, and the two are integrated. The extension portion 11b extends in a direction away from the other end of the connecting portion 11a. The stationary contact bracket as a whole is shaped like a slender sub-moving contact piece. The extension portion 11b in the stationary contact bracket can provide a contact area for the connection between the moving contact assembly 12 and the stationary contact assembly 11, making it easier to flexibly install and arrange the moving contact assembly 12, and also facilitating the design of a more compact moving contact assembly 12.

[0119] Optionally, referring to FIG5, the first stationary contact bracket 112 is electrically connected to the second stationary contact lead-out end 111b through the connecting part 11a, and extends toward the first stationary contact lead-out end 111a and is spaced apart from it;

[0120] The second stationary contact bracket 113 is electrically connected to the third stationary contact lead-out end 111c through the connecting part 11a, and extends toward the fourth stationary contact lead-out end 111d and is spaced apart from it.

[0121] Specifically, in one embodiment, as shown in FIG5, the connecting portion 11a of the first stationary contact bracket 112 can be fixed below the second stationary contact lead-out end 111b by riveting or welding, and the extension portion 11b of the first stationary contact bracket 112 extends toward the first stationary contact lead-out end 111a along the X direction shown in the figure and is spaced apart from it.

[0122] The connecting portion 11a of the second stationary contact bracket 113 can be fixed below the third stationary contact lead-out end 111c by riveting or welding. The extension portion 11b of the second stationary contact bracket 113 extends toward the fourth stationary contact lead-out end 111d along the X direction shown in the figure and is spaced apart from it.

[0123] Optionally, referring to Figures 2 and 5, the two moving contact assemblies 12 include a first moving contact assembly 121 and a second moving contact assembly 122;

[0124] The first moving contact assembly 121 is used to connect the first stationary contact lead-out end 111a to the first stationary contact support 112, and is also used to connect the fourth stationary contact lead-out end 111d to the second stationary contact support 113.

[0125] The second moving contact assembly 122 is used to connect the second stationary contact lead-out terminal 111b and the third stationary contact lead-out terminal 111c.

[0126] Specifically, in one embodiment, as shown in Figures 2 and 5, when there are two moving contact assemblies 12, they may include a first moving contact assembly 121 and a second moving contact assembly 122, which are perpendicular to each other in the horizontal plane. Neither the first moving contact assembly 121 nor the second moving contact assembly 122 simultaneously contacts and conducts electricity with the stationary contact assembly 11.

[0127] As shown in Figure 5, when the first moving contact assembly 121 moves upward along the Z direction as illustrated, one end of a portion of the first moving contact assembly 121 contacts the first stationary contact lead-out terminal 111a, and the other end contacts the first stationary contact support 112. The first moving contact assembly 121 connects the first stationary contact lead-out terminal 111a and the first stationary contact support 112, forming one path. Simultaneously, one end of the other portion of the first moving contact assembly 121 contacts the fourth stationary contact lead-out terminal 111d, and the other end contacts the second stationary contact support 113. The first moving contact assembly 121 also connects the fourth stationary contact lead-out terminal 111d and the second stationary contact support 113, forming another path. Therefore, the first moving contact assembly 121 can control the relay to form at least two independent paths.

[0128] As shown in Figure 5, the second moving contact assembly 122 spans between the first stationary contact bracket 112 and the second stationary contact bracket 113. When the second moving contact assembly 122 moves upward along the Z direction as shown in the figure, one end of the second moving contact assembly 122 contacts the first stationary contact bracket 112, and the other end contacts the second stationary contact bracket 113. The second moving contact assembly 122 indirectly connects the second stationary contact lead-out end 111b and the third stationary contact lead-out end 111c through the two stationary contact brackets, forming a path. Furthermore, it should be noted that in some embodiments, the lower end of the second stationary contact lead-out 111b can pass through the through hole on the first stationary contact bracket 112 and extend from the bottom of the first stationary contact bracket 112, and the lower end of the third stationary contact lead-out 111c can pass through the through hole on the second stationary contact bracket 113 and extend from the bottom of the second stationary contact bracket 113. In this structure, after the second moving contact assembly 122 moves upward, the second moving contact assembly 122 can directly connect the second stationary contact lead-out 111b and the third stationary contact lead-out 111c to form a path.

[0129] Optionally, referring to FIG5, the first moving contact assembly 121 is arranged along the line connecting the first stationary contact lead-out end 111a and the second stationary contact lead-out end 111b;

[0130] The second moving contact assembly 122 is arranged along the line connecting the second stationary contact lead-out end 111b and the third stationary contact lead-out end 111c.

[0131] Specifically, in one embodiment, as shown in FIG5, the line connecting the first stationary contact lead-out end 111a and the second stationary contact lead-out end 111b is in the X direction as shown in the figure, and the line connecting the second stationary contact lead-out end 111b and the third stationary contact lead-out end 111c is in the Y direction as shown in the figure, with the X and Y directions being perpendicular to each other. The first moving contact assembly 121 is arranged along the X direction, with one end facing the stationary contact support and the other end facing the stationary contact lead-out end. The second moving contact assembly 122 is arranged along the Y direction, with one end facing the first stationary contact support 112 and the other end facing the second stationary contact support 113.

[0132] It should be noted that the orientation of the first moving contact assembly 121 and the second moving contact assembly 122 in the embodiments of this application refers to the orientation of the long side of the moving contact piece used to contact the stationary contact assembly 11.

[0133] Optionally, referring to Figures 2, 5 to 10, the first moving contact assembly 121 includes: a first moving contact piece 1211 and a second moving contact piece 1212;

[0134] The first movable contact 1211 and the second movable contact 1212 are connected to the same pushing component 10, and the first movable contact 1211 and the second movable contact 1212 are spaced apart from each other;

[0135] The first movable contact 1211 is used to connect the first stationary contact lead-out end 111a to the first stationary contact bracket 112, and the second movable contact 1212 is used to connect the fourth stationary contact lead-out end 111d to the second stationary contact bracket 113.

[0136] Specifically, in one embodiment, as shown in FIG2, the first moving contact assembly 121 of this application embodiment may include two parts: a first moving contact piece 1211 and a second moving contact piece 1212. The first moving contact piece 1211 and the second moving contact piece 1212 are integrated and mounted together and connected to the same pushing assembly 10. When the pushing assembly 10 moves, the first moving contact piece 1211 and the second moving contact piece 1212 move up and down together, moving closer to or away from the stationary contact assembly 11.

[0137] Referring to the illustrations in Figures 5 to 10, when the first moving contact assembly 121 moves as a whole and comes into contact with the stationary contact assembly 11, two independent paths can be formed. Therefore, the first moving contact piece 1211 and the second moving contact piece 1212 are spaced apart from each other along the Y direction shown in the figures. Specifically, the first moving contact piece 1211 is used to connect the first stationary contact lead-out end 111a with the first stationary contact support 112 to form one path, and the second moving contact piece 1212 is used to connect the fourth stationary contact lead-out end 111d with the second stationary contact support 113 to form another path.

[0138] In this type of relay, since the first moving contact assembly 121 itself can construct two paths using a push assembly 10, the relay has a high degree of integration.

[0139] Optionally, referring to FIG5, at least one of the first movable contact 1211 and the second movable contact 1212 includes not less than two sub-movable contacts arranged in parallel.

[0140] Specifically, as shown in Figure 5, in the relay of this embodiment, either the first moving contact 1211 or the second moving contact 1212 can be composed of two or more sub-moving contacts arranged side by side and assembled together. This reduces the contact resistance of the moving contacts, decreases power consumption, and makes the relay more energy-efficient. Furthermore, it can be understood that in the relay of this embodiment, either the first moving contact 1211 or the second moving contact 1212 can also be a single sub-moving contact structure as shown in Figure 6, to reduce material consumption.

[0141] Optionally, referring to Figures 2, 5, 9 and 10, the second moving contact assembly 122 includes a third moving contact piece 1221;

[0142] The third movable contact 1221 is connected to another of the aforementioned push components 10;

[0143] The third moving contact 1221 is used to connect the first stationary contact bracket 112 and the second stationary contact bracket 113.

[0144] Specifically, as shown in FIG2, the second movable contact assembly 122 of this application embodiment may include a third movable contact piece 1221. The third movable contact piece 1221 is connected to another pushing assembly 10, which is not the same pushing assembly 10 as the pushing assembly 10 to which the first movable contact piece 1211 and the second movable contact piece 1212 are connected.

[0145] Referring to the diagrams in Figures 5, 9, and 10, when the second moving contact assembly 122 moves as a whole and makes contact with the stationary contact assembly 11, one end of the third moving contact piece 1221 makes contact with the first stationary contact bracket 112, and the other end of the third moving contact piece 1221 makes contact with the second stationary contact bracket 113. At this time, the relay forms a path corresponding to "second stationary contact lead-out 111b - first stationary contact bracket 112 - second stationary contact bracket 113 - third stationary contact lead-out 111c".

[0146] Optionally, referring to FIG5, the third movable contact 1221 includes no less than two sub-movable contacts arranged in parallel.

[0147] Specifically, as shown in Figure 5, in the relay of this embodiment, similar to the first moving contact 1211 and the second moving contact 1212, the third moving contact 1221 can also be a moving contact composed of two or more sub-moving contacts arranged side by side and assembled together. This reduces the contact resistance of the moving contact, decreases power consumption, and makes the relay more energy-efficient. Furthermore, it can be understood that in the relay of this embodiment, the third moving contact 1221 can also be a single sub-moving contact structure as shown in Figure 6, to reduce material consumption.

[0148] Optionally, referring to Figures 2, 11 and 12, the moving contact assembly 12 further includes an elastic component 123;

[0149] A set of elastic components 123 is disposed between the first moving contact assembly 121 and the pushing assembly 10; and / or,

[0150] A set of elastic components 123 is provided between the second moving contact assembly 122 and the pushing assembly 10.

[0151] Specifically, in one embodiment, referring to the schematic diagram in FIG2, the moving contact assembly 12 in the relay of this application embodiment may further include an elastic component 123. The elastic component 123 is not limited to a compression spring or a reed with elasticity. The elastic component 123 is disposed between the moving contact assembly 12 and the pushing component 10. The elastic force generated forces the moving contact assembly 12 and the pushing component 10 to tend to move away from each other. The elastic component 123 is further compressed, thereby increasing the contact pressure between the moving contact assembly 12 and the stationary contact assembly 11, which makes the path formed by the stationary contact lead-out end 111 stable and reliable. FIG11 shows a schematic diagram of the elastic component 123 acting on the first moving contact assembly 121, and FIG12 shows a schematic diagram of the elastic component 123 acting on the second moving contact assembly 122. Specifically, since the first moving contact assembly 121 and the second moving contact assembly 122 are each connected to different pushing components 10, a set of elastic components 123 is located between the first moving contact assembly 121 and the corresponding pushing component 10. Another set of elastic components 123 is located between the second moving contact assembly 122 and the corresponding actuating assembly 10.

[0152] Optionally, referring to Figures 2, 13 to 16, the relay further includes a first magnetic conductor 13;

[0153] Along the direction of movement of the pushing component 10, the first moving contact 1211 is provided with a first magnetic conductor 13 on the side near the stationary contact lead-out end 111, and the second moving contact 1212 is provided with a first magnetic conductor 13 on the side near the stationary contact lead-out end 111. The first magnetic conductor 13 is used to resist the electric repulsive force between the moving contact and the corresponding stationary contact lead-out end 111.

[0154] Specifically, as shown in Figures 2 and 13 to 16, the relay in this embodiment further includes a first magnetic conductor 13, which may be a plurality of stacked magnetic sheets. Along the Z-direction of movement of the pushing assembly 10, a portion of the first magnetic conductor 13 is installed on the side of the first moving contact 1211 near the stationary contact lead-out end 111, and another portion of the first magnetic conductor 13 is installed on the side of the second moving contact 1212 near the stationary contact lead-out end 111. Both portions of the first magnetic conductor 13 remain stationary.

[0155] When the moving contact assembly 12 moves upward to contact the stationary contact assembly 11, the upper first magnetic conductor 13 can resist the electro-repulsive force between the first moving contact piece 1211, the second moving contact piece 1212, and the stationary contact lead-out end 111. Therefore, the stationary first magnetic conductor 13 can improve the tightness of the contact and engagement between the moving contact piece and the stationary contact lead-out end 111, preventing the electro-repulsive force caused by the short-circuit current from separating the two.

[0156] Optionally, referring to Figures 2, 13 to 16, the relay further includes a second magnetic conductor 14;

[0157] Along the direction of movement of the pushing component 10, the first moving contact 1211 and the second moving contact 1212 are both provided with the second magnetic conductor 14 on the side opposite to the stationary contact lead-out end 111.

[0158] A magnetic circuit is formed between the first magnetic conductor 13 and the second magnetic conductor 14 to resist the electric repulsion between the moving contact and the corresponding stationary contact lead-out end 111.

[0159] Specifically, as shown in Figures 2 and 13 to 16, the relay in this embodiment further includes a second magnetic conductor 14. The second magnetic conductor 14 may be a U-shaped magnetic sheet.

[0160] Along the Z-direction of movement of the push assembly 10, a portion of the second magnetic conductor 14 is installed on the side of the first moving contact 1211 away from the stationary contact lead-out end 111. Thus, when the moving contact assembly 12 moves upward to contact the stationary contact assembly 11, the upper first magnetic conductor 13 and the portion of the second magnetic conductor 14 can form a closed magnetic loop, which can more stably and reliably keep the first moving contact 1211 in the conducting position.

[0161] Along the Z-direction of movement of the push assembly 10, another part of the second magnetic conductor 14 is installed on the side of the second moving contact 1212 away from the stationary contact lead-out end 111. Thus, when the moving contact assembly 12 moves upward to contact the stationary contact assembly 11, the upper first magnetic conductor 13 and this part of the second magnetic conductor 14 can form a closed magnetic loop, which can more stably and reliably keep the first moving contact 1211 in the conducting position.

[0162] Optionally, referring to FIG2, each of the stationary contact lead-out terminals 111 includes a load connection portion 1111 and a contact portion 1112, wherein the load connection portion 1111 and the contact portion 1112 are connected as one unit;

[0163] Each of the contact portions 1112 is disposed near the moving contact assembly 12 for contacting or disconnecting from the moving contact assembly 12;

[0164] Each of the load connection portions 1111 is disposed away from the moving contact assembly 12 and is used for electrical connection with a load circuit outside the relay.

[0165] Specifically, as illustrated in Figure 2, in the relay of this embodiment, all stationary contact leads 111 are located on the same side of the push assembly 10 in the direction of movement of the push assembly 10. That is, all stationary contact leads 111 can be located at the same end in the direction of movement of the push assembly 10, such as the upper end in the Z direction as shown in the figure. Referring to the illustration in Figure 2, each stationary contact lead 111, like the fourth stationary contact lead 111d, has a load connection portion 1111 and a contact portion 1112. The load connection portion 1111 and the contact portion 1112 can be a cylindrical structure integrated together. The load connection portion 1111 is located at the upper position away from the moving contact assembly 12, and the contact portion 1112 is located at the lower position close to the moving contact assembly 12. The diameter of the load connection portion 1111 can be larger than that of the contact portion 1112, and the height of the load connection portion 1111 can be smaller than that of the contact portion 1112. Thus, the load connection portion 1111 can form a disc-shaped flange and can be machined with a structure for connecting the load circuit outside the relay, such as a threaded structure for connecting the copper busbar or a welding plane for laser welding the copper busbar. For more forms of load connection portion 1111, they will not be described in detail here. Additionally, it should be noted that when the stationary contact assembly 11 also includes a first stationary contact bracket 112 and a second stationary contact bracket 113, the connecting portion 11a of the first stationary contact bracket 112 is connected to the contact portion 1112 of a stationary contact lead-out end 111 (as shown in Figure 9, the first stationary contact lead-out end 111a), and the connecting portion 11a of the second stationary contact bracket 113 is connected to the contact portion 1112 of another stationary contact lead-out end 111 (as shown in Figure 9, the third stationary contact lead-out end 111c). In this case, the thickness of the first stationary contact bracket 112 and the second stationary contact bracket 113 occupies a portion of the space below the corresponding stationary contact lead-out end 111. To ensure that the load connection portions 1111 of each stationary contact lead-out terminal 111 located at the upper part of the Z direction are at the same height and that the end faces of these portions are flush, while also ensuring that the relay can conduct normally, in this embodiment, the heights of the contact portions 1112 of each stationary contact lead-out terminal 111 are not completely the same. The height of the contact portions 1112 of the stationary contact lead-out terminals 111 that are not connected to the stationary contact support is larger. This allows the moving contact assembly 12 to move to the first position, where some of the moving contact assembly 12 directly contacts and conducts with some of the contact portions 1112 of the stationary contact lead-out terminals 111, while the other part of the moving contact assembly 12 contacts the stationary contact support and conducts with the corresponding stationary contact lead-out terminal 111. At this time, the contact portions of the stationary contact assembly 11 and the moving contact assembly 12 are in the same plane, which helps to ensure that each formed path is effectively and reliably connected, preventing poor contact or disconnection, and improving the reliability of the relay. Therefore, the stationary contact leads 111 are arranged in a concentrated manner at the same end, which can improve the convenience of wiring. In addition, the concentrated and compact layout structure can reduce the space occupied by the relay and is more conducive to miniaturization design.

[0166] Optionally, referring to Figures 1 and 2, the relay further includes a coil 20, and the actuation assembly includes an actuation rod 101;

[0167] The push rod 101 is movably inserted into the cavity of the coil 20, and the coil 20 is used to drive the push rod 101 to move the moving contact assembly 12.

[0168] Specifically, in one embodiment of the relay of this application, as shown in Figures 1 and 2, the relay further includes a coil 20, and the pushing assembly 10 includes a pushing rod 101. The pushing rod 101 is movably disposed in the cavity of the coil 20. When the coil 20 is energized, it generates an electromagnetic force acting on the pushing rod 101. Thus, the electromagnetic force generated by the coil 20 drives the pushing rod 101 to move along the Z direction as shown in the figures, thereby driving the moving contact assembly 12 to move, causing the moving contact assembly 12 to move closer to or further away from the stationary contact assembly 11.

[0169] Optionally, the moving contact assembly 12 is connected to one end of the push rod 101. The relay also includes a moving iron core, which is movably disposed in the cavity of the coil 20 and connected to the other end of the push rod 101. The length direction of the moving contact piece in the moving contact assembly 12 is perpendicular to the movement direction of the push rod 101. The push rod 101 drives the moving contact assembly 12 to move linearly relative to the stationary contact assembly 11 along the axial direction of the push rod 101.

[0170] Specifically, in one embodiment of the relay of this application, each moving contact piece in the moving contact assembly 12 is mounted on one end of the push rod 101 via a connector or the like, and the length direction of the moving contact piece is perpendicular to the axis of the push rod 101. A moving iron core (not shown in the figure) is fixed to the other end of the push rod 101. When the other end of the push rod 101 extends into the coil 20, and the moving iron core is driven by the electromagnetic force of the coil 20, the push rod 101 moves linearly along the axis of the coil 20, correspondingly driving the moving contact assembly 12 to move linearly, thereby moving closer to or further away from the stationary contact assembly 11 to achieve the on / off control of the relay.

[0171] Optionally, referring to Figure 9 or Figure 10, when the moving contact assembly 12 and the stationary contact assembly 11 form a path, the load current flows from one of the stationary contact leads 111 connected at one end of the moving contact assembly 12 to another stationary contact lead 111 connected at the other end of the moving contact assembly 12.

[0172] Specifically, in one embodiment, when another part of the moving contact assembly 12 moves to be in contact with the stationary contact assembly 11, for example, as shown in the schematic of FIG9 or FIG10, the second moving contact assembly 122 connects the stationary contact assembly 11. At this time, one end of the second moving contact assembly 122 overlaps with the connection portion 11a of a stationary contact bracket, and the other end of the second moving contact assembly 122 overlaps with the connection portion 11a of another stationary contact bracket. Thus, in this embodiment, the current flows through one stationary contact lead-out end 111 to one end of the second moving contact assembly 122, and along the length direction of the second moving contact assembly 122 to the other stationary contact lead-out end 111. That is, the relay can form a path by relying on the two overlapping contact relationships formed at both ends of the second moving contact assembly 122 along the length direction. There are fewer contact points, the contact resistance is smaller, and correspondingly, the structure is simpler, which also helps to miniaturize the relay.

[0173] Optionally, in the relay of this application embodiment, when the number of stationary contact leads 111 is M (M≥4), when a portion of the moving contact assembly 12 moves to conduct with the stationary contact assembly 11, the number of multiple paths formed by the M stationary contact leads 111 is a. When another portion of the moving contact assembly 12 moves to conduct with the stationary contact assembly 11, the number of at least one path formed by the M stationary contact leads 111 is b. The total number of paths N that this relay product can form in different working states is a+b, and N is greater than M / 2. Therefore, this relay has multiple connection and usage methods and can be flexibly applied to load control circuits.
