Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of controlling switch, and particularly relates to a relay. BACKGROUND

[0002] In the electrical engineering industry, a relay is widely used as a kind of control device, which has a control system (also called an input loop) and a controlled system (also called an output loop), and is usually applied to an automatic control circuit. The relay is actually a kind of "automatic switch" for controlling a larger current with a smaller current. Therefore, the relay plays a role of automatic adjustment, safety protection and conversion of a circuit.

[0003] In the existing high-voltage direct-current relay, when it is required to realize automatic switching control of multiple loops, a relay needs to be arranged in the corresponding loop, which leads to an increase in the use cost of the relay, and the relay needs to be installed and connected at multiple positions, which also increases the difficulty of the installation and layout of the relay.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0089] 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.

[0090] Reference Figure 1 Figure 5 shows a schematic diagram of the structure of a relay according to an embodiment of this application. The relay includes:

[0091] Drive component 10;

[0092] A stationary contact assembly 11, the stationary contact assembly 11 including at least four stationary contact leads 111;

[0093] A moving contact assembly 12 is connected to the pushing assembly 10, and the pushing assembly 10 drives the stationary contact assembly of the moving contact assembly 12 to move relative to the stationary contact assembly 11.

[0094] When the moving contact assembly 12 moves to the first position, at least four of the stationary contact leads 111 form multiple independent paths; when the moving contact assembly 12 moves to the second position, at least four of the stationary contact leads 111 form at least one path.

[0095] like Figure 1 The diagram shown is an exploded view of the structure of a relay according to an embodiment of this application. Figure 1 In the middle, the actuating component 10, the stationary contact component 11, and the moving contact component 12 (see...) Figure 2 and Figure 3The components 10, 12, and 11 are assembled together to form a relay switching system. The driving component 10 can be driven by the driving force output by the driving system 2, thereby causing the moving contact component 12 to move relative to the stationary contact component 11, thus realizing the switching control of the relay. It should be noted that the driving force output by the driving 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 the coil, and the force generated by mechanical motion can be the force generated by the device that converts electrical energy into mechanical energy. This application embodiment does not limit the structure of the driving system 2 or the type of driving force. It is easy to understand that when the driving component 10 drives the moving contact component 12 to contact the stationary contact component 11, the relay is in a conducting state; when the driving component 10 drives the moving contact component 12 to separate from the stationary contact component 11, the relay is in a disconnected state. The driving component 10, the stationary contact component 11, and the moving contact component 12 can all be installed in the plastic housing 30, which protects these components. Of course, the plastic housing 30 also serves as a support or bracket structure for installing and fixing these components.

[0096] 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 no less than four stationary contact leads 111 spaced apart from each other. 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.

[0097] The moving contact assembly 12 is connected to the 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, the moving contact assembly 12 can move and remain in at least two different positions: a first position and a second position. When the moving contact assembly 12 moves to the first position, at least four stationary contact leads 111 form multiple independent paths. At this time, each independent path can control a load device. In this condition, multiple load devices or multiple load circuits can be controlled using a single relay. When the moving contact assembly 12 moves to the second position, at least four stationary contact leads 111 form at least one path. In this condition, at least one load circuit can be controlled using a single relay. It is understood that when the moving contact assembly 12 moves to the second position, if there are two or more paths formed, the paths can be electrically connected or independently disconnected, depending on whether the corresponding moving contact assembly 12 conducts each path. This application embodiment does not limit this.

[0098] It should be noted that, Figure 2 An exploded view of an on / off system according to an embodiment of this application is shown. Figure 2 The relay shown in the image has four stationary contact leads 111. Figure 3 for Figure 2 The corresponding assembly drawing. When the push assembly 10 moves upward along the Z direction as shown in the figure to the first position, the four stationary contact leads 111 can form two independent paths. When the push assembly 10 moves downward along the Z direction as shown in the figure to the second position, the four stationary contact leads 111 can form one path.

[0099] also, Figure 4 A schematic diagram is shown showing six stationary contact leads 111 forming three independent paths, namely, path L1 formed by the first stationary contact lead 111a and the second stationary contact lead 111b, path L2 formed by the third stationary contact lead 111c and the fourth stationary contact lead 111d, and path L3 formed by the fifth stationary contact lead 111e and the sixth stationary contact lead 111f.

[0100] Figures 5a to 5c A simplified schematic diagram is also shown showing a path formed by six stationary contact leads 111, which can be a path formed between the first stationary contact lead 111a, the third stationary contact lead 111c, the fifth stationary contact lead 111e, and any other stationary contact lead. For example, as... Figure 5aAs shown, when one stationary contact lead-out of the passive contact assembly 12 is the first stationary contact lead-out 111a, the other stationary contact lead-out of the moving contact assembly 12 can be the second stationary contact lead-out 111b, the third stationary contact lead-out 111c, the fourth stationary contact lead-out 111d, the fifth stationary contact lead-out 111e, or the sixth stationary contact lead-out 111f. In this case, the relay forms a circuit including five different conduction connection schemes, and one circuit is... Figure 5a Any one of S1, S2, S3, S4, and S5 shown in the diagram. For example... Figure 5b As shown, when one stationary contact lead-out of the passive contact assembly 12 is the third stationary contact lead-out 111c, the other stationary contact lead-out of the moving contact assembly 12 can be the second stationary contact lead-out 111b, the fourth stationary contact lead-out 111d, the fifth stationary contact lead-out 111e, or the sixth stationary contact lead-out 111f. In this case, the relay forms a circuit including four different conduction connection schemes, and one circuit is... Figure 5b Any one of S6, S7, S8, and S9 shown in the diagram. For example... Figure 5c As shown, when one stationary contact lead-out of the passive contact assembly 12 is the fifth stationary contact lead-out 111e, the other stationary contact lead-out of the moving contact assembly 12 can be the second stationary contact lead-out 111b, the fourth stationary contact lead-out 111d, or the sixth stationary contact lead-out 111f. In this case, the relay forms a circuit including three different conduction connection schemes. One circuit is... Figure 5c Any one of S10, S11, and S12 shown in the diagram.

[0101] Therefore, in the relay of this application embodiment, the stationary contact assembly includes at least four stationary contact leads spaced apart from each other, and the moving contact assembly is connected to the pushing assembly. By driving the moving contact assembly to two different positions through the pushing assembly, multiple independent paths or at least one 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 operating modes, which helps to reduce the cost of using the relay and reduce the complexity of the installation layout.

[0102] Optionally, refer to Figures 4 to 7 When the moving contact assembly 12 moves to the first position, at least two of the four stationary contact leads 111 are simultaneously connected to form multiple independent paths.

[0103] When the moving contact assembly 12 moves to the second position, one of the at least four stationary contact leads 111 becomes connected to one of the remaining stationary contact leads 111 to form a path.

[0104] Specifically, such as Figure 6 and Figure 7 As shown, in one embodiment, when there are four 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, and a fourth stationary contact lead 111d. When the moving contact assembly 12 moves to the first position, the first stationary contact lead 111a and the second stationary contact lead 111b are connected to form a first path, and the third stationary contact lead 111c and the fourth stationary contact lead 111d are connected to form a second path. When the moving contact assembly 12 moves to the second position, the first stationary contact lead 111a can be connected to one of the remaining second stationary contact leads 111b, third stationary contact lead 111c, and fourth stationary contact lead 111d to form a path.

[0105] like Figures 4 to 5c As shown, 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. When the moving contact assembly 12 moves to the first position, the first stationary contact lead 111a and the second stationary contact lead 111b are connected to form a first path, the third stationary contact lead 111c and the fourth stationary contact lead 111d are connected to form a second path, and the fifth stationary contact lead 111e and the sixth stationary contact lead 111f are connected to form a third path. When the moving contact assembly 12 moves to the second position, the first stationary contact lead-out end 111a can form a circuit with one of the remaining second stationary contact lead-out ends 111b, third stationary contact lead-out ends 111c, fourth stationary contact lead-out ends 111d, fifth stationary contact lead-out ends 111e, and sixth stationary contact lead-out ends 111f.

[0106] Combination Figures 4 to 7 As illustrated, regardless of the number of stationary contact leads 111, when multiple independent paths are formed in the relay, every two stationary contact leads 111 are in the same path. Correspondingly, the two stationary contact leads 111 forming this path will not appear repeatedly in other paths. When the number of stationary contact leads 111 is even greater, the relay can form multiple independent paths or a single path according to the above connection relationship; this will not be further elaborated in the embodiments of this application.

[0107] Optionally, refer to Figure 2 The number of the pushing components 10 is one.

[0108] Specifically, in one embodiment, the relay of this application can use a single push component 10 to drive the moving contact component 12 to move in two opposite directions, thereby reaching a first position and a second position. Compared to using more push components 10, this relay product utilizes only one push component 10, which helps to achieve miniaturization of the relay and facilitates its installation and use in confined spaces. Furthermore, it should be noted that in other embodiments, two or more push components 10 can be used, connected one-to-one with the same number of moving contact components 12, and each can independently drive the movement of the moving contact component 12, thereby achieving more flexible control of the moving contact component 12.

[0109] Optionally, refer to Figure 2 and Figure 3 The 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.

[0110] Specifically, in one implementation, such as Figure 2 and Figure 3 As illustrated in the illustration, in the relay of this application embodiment, when the number of stationary contact leads 111 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 operate 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.

[0111] Optionally, refer to Figure 2 and Figure 3 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. The first stationary contact lead-out end 111a and the third stationary contact lead-out end 111c are 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 are located on the other diagonal of the rectangle.

[0112] Specifically, in one implementation, such as Figure 2 and Figure 3As illustrated in this embodiment of the relay, 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.

[0113] Optionally, refer to Figure 2 and Figure 3 The stationary contact assembly 11 further includes a first stationary contact bracket 112 and a second stationary contact bracket 113;

[0114] The first stationary contact bracket 112 is electrically connected to one of the four stationary contact leads 111;

[0115] The second stationary contact bracket 113 is electrically connected to one of the remaining stationary contact leads 111;

[0116] The first stationary contact bracket 112 and the second stationary contact bracket 113 are arranged opposite to each other to form a receiving space for mounting the moving contact assembly 12;

[0117] The movable contact assembly 12 is located within the receiving space and moves between the first position and the second position.

[0118] Specifically, in one implementation, such as Figure 2 and Figure 3 The illustration, taking four stationary contact leads 111 as an example, shows that in the relay of this application embodiment, the stationary contact assembly 11 further includes a first stationary contact bracket 112 and a second stationary contact bracket 113. Both stationary contact brackets 113 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 relatively at intervals, and the empty portion in the middle can be used to install and accommodate the moving contact assembly 12.

[0119] When the moving contact assembly 12 moves to the first position within the receiving space formed by the first stationary contact bracket 112 and the second stationary contact bracket 113, the first stationary contact bracket 112 and the second stationary contact bracket 113 are in the disconnected state, and the two stationary contact lead-out ends 111 can be connected to form two independent paths.

[0120] When the moving contact assembly 12 moves to the second position within the receiving space formed by the first stationary contact bracket 112 and the second stationary contact bracket 113, the first stationary contact bracket 112 and the second stationary contact bracket 113 are in a conductive state, which can connect the two stationary contact leads 111 connected by the first stationary contact bracket 112 and the second stationary contact bracket 113 to form an independent path.

[0121] Optionally, refer to Figure 8 or Figure 9 Both the first stationary contact bracket 112 and the second stationary contact bracket 113 include a connecting part 11a, a supporting part 11b, and an overlapping part 11c.

[0122] The connecting part 11a is connected to one end of the supporting part 11b, and the overlapping part 11c is connected to the other end of the supporting part 11b. The three together form a groove to accommodate the moving contact assembly 12.

[0123] The groove openings of the first stationary contact bracket 112 and the second stationary contact bracket 113 are opposite to each other to form the receiving space;

[0124] The connecting part 11a is electrically connected to a stationary contact lead-out end 111, and the overlapping part 11c is used for the moving contact assembly 12 to abut against.

[0125] 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 and bending process, which can reduce the processing steps of the stationary contact bracket and improve manufacturing efficiency.

[0126] like Figure 8 or Figure 9 As illustrated, any stationary contact bracket may include a connecting portion 11a, a supporting portion 11b, and an overlapping portion 11c. The supporting portion 11b is located between the connecting portion 11a and the overlapping portion 11c. One end of the supporting portion 11b is connected to the connecting portion 11a, and the other end of the supporting portion 11b is connected to the overlapping portion 11c. The connecting portion 11a is bent at a 90-degree angle relative to the supporting portion 11b, and the overlapping portion 11c is bent at a 90-degree angle relative to the supporting portion 11b. The three parts are connected as a whole to form a U-shaped part. The groove formed by the three parts is used to accommodate the moving contact assembly 12.

[0127] Combination Figure 8 or Figure 9As shown in the illustration, when the stationary contact bracket is connected to the stationary contact lead-out end 111, the connecting part 11a can be welded or riveted to the bottom of a stationary contact lead-out end 111, the supporting part 11b extends along the Z direction shown in the illustration and is parallel to the axis of the stationary contact lead-out end 111, and the overlapping part 11c is located opposite to the connecting part 11a and can abut against it when the moving contact assembly 12 moves downward.

[0128] Thus, the groove openings of the first stationary contact bracket 112 and the second stationary contact bracket 113 form a receiving space. When the moving contact assembly 12 moves upward along the Z direction to the first position in the receiving space, the four stationary contact leads 111 can form two independent paths. When the moving contact assembly 12 moves downward along the Z direction to the second position in the receiving space, the four stationary contact leads 111 can form one path.

[0129] Optionally, refer to Figure 8 , Figure 10 and Figure 11 The connecting part 11a of the first stationary contact bracket 112 is electrically connected to the first stationary contact lead-out end 111a, and the connecting part 11a of the second stationary contact bracket 113 is electrically connected to the third stationary contact lead-out end 111c.

[0130] The first stationary contact bracket 112 and the second stationary contact bracket 113 are centrally symmetrical about the center of the four stationary contact leads 111, and the moving contact assembly 12 is located within the receiving space.

[0131] Specifically, in one implementation, such as Figure 8 , Figure 10 and Figure 11 As shown, the connecting portion 11a of the first stationary contact bracket 112 is electrically connected to the first stationary contact lead-out terminal 111a, and the overlapping portion 11c of the first stationary contact bracket 112 extends below the fourth stationary contact lead-out terminal 111d. The connecting portion 11a of the second stationary contact bracket 113 is electrically connected to the third stationary contact lead-out terminal 111c, and the overlapping portion 11c of the second stationary contact bracket 113 extends below the second stationary contact lead-out terminal 111b. At this time, the first stationary contact bracket 112 and the second stationary contact bracket 113 have a centrally symmetrical structure around the center of the four stationary contact leads-out terminals 111.

[0132] Optionally, refer to Figure 9 , Figure 12 and Figure 13 The connecting part 11a of the first stationary contact bracket 112 is electrically connected to the third stationary contact lead-out end 111c, and the connecting part 11a of the second stationary contact bracket 113 is electrically connected to the fourth stationary contact lead-out end 111d.

[0133] The first stationary contact bracket 112 and the second stationary contact bracket 113 are arranged in a mirror-symmetric structure around the center of the four stationary contact leads, and the moving contact assembly 12 is located within the receiving space.

[0134] Specifically, in one embodiment, the first stationary contact bracket 112 and the second stationary contact bracket 113 can also be configured as follows: Figure 9 , Figure 12 as well as Figure 13 The schematic diagram shows the connection to the stationary contact lead-out terminal 111. The connecting portion 11a of the first stationary contact bracket 112 is electrically connected to the third stationary contact lead-out terminal 111c, and the connecting portion 11a of the second stationary contact bracket 113 is electrically connected to the fourth stationary contact lead-out terminal 111d. At this time, the extension length of the overlapping portion 11c along the length direction X of the groove depends on the size of the moving contact assembly 12 in the X direction, ensuring that the moving contact assembly 12 is fully in contact with the overlapping portion 11c in the X direction. At this time, the first stationary contact bracket 112 and the second stationary contact bracket 113 have a mirror-symmetrical structure around the center of the four stationary contact lead-out terminals 111.

[0135] It should be noted that in this embodiment of the application, the first stationary contact bracket 112 and the second stationary contact bracket 113 adopt a centrally symmetrical structure or a mirror symmetrical structure, and the corresponding moving contact assembly 12 structure can be designed respectively to meet the structural requirements under different automation control scenarios, so as to better match and adapt to the installation environment.

[0136] Optionally, refer to Figures 10 to 13 The movable contact assembly 12 includes a first upper movable contact piece 121, a second upper movable contact piece 122, and a lower movable contact piece 123, all of which are connected to the push assembly 10.

[0137] Along the movement direction of the pushing component 10, the first upper movable contact 121 and the lower movable contact 123 are spaced apart, and the second upper movable contact 122 and the lower movable contact 123 are spaced apart;

[0138] Along a direction perpendicular to the movement direction of the pushing component 10, the first upper movable contact 121 and the second upper movable contact 122 are spaced apart;

[0139] When the moving contact assembly 12 moves to the first position, the first upper moving contact piece 121 conducts two of the stationary contact lead-out ends 111 to form a path, and the second upper moving contact piece 122 conducts the other two of the stationary contact lead-out ends 111 to form another path.

[0140] When the moving contact assembly 12 moves to the second position, the lower moving contact piece 123 connects two of the stationary contact lead-out ends 111 to form a path.

[0141] Specifically, in one implementation, combined with Figures 11 to 13 As illustrated, the moving contact assembly 12 in this embodiment can be an assembly formed by two layers of moving contact pieces, specifically including a first upper moving contact piece 121 and a second upper moving contact piece 122 located on the upper layer, and a lower moving contact piece 123 located on the lower layer. It should be noted that the upper and lower positions in this embodiment are referenced to the Z-direction of the movement direction of the pushing assembly 10. Along the Z-direction of the movement direction of the pushing assembly 10, the part closer to the stationary contact lead-out end 111 is the upper position, and the part farther from the stationary contact lead-out end 111 is the lower position.

[0142] The first upper movable contact 121 and the second upper movable contact 122 are located on the same layer and are both connected to the push assembly 10. The lower movable contact 123 is stacked on top of the first upper movable contact 121 and the second upper movable contact 122 and is also connected to the push assembly 10. Furthermore, the first upper movable contact 121 and the second upper movable contact 122 on the upper layer are spaced apart from each other.

[0143] like Figure 10 As illustrated, when the moving contact assembly 12 moves upward to the first position, the first upper moving contact 121 can connect the first stationary contact lead-out end 111a and the second stationary contact lead-out end 111b to form a first path. At the same time, the second upper moving contact 122 can connect the third stationary contact lead-out end 111c and the fourth stationary contact lead-out end 111d to form a second path.

[0144] like Figure 11 As illustrated, when the moving contact assembly 12 moves downward to the second position, the first upper moving contact 121 and the second upper moving contact 122 separate from the upper stationary contact lead-out end 111, and the lower moving contact 123 can connect the first stationary contact lead-out end 111a and the third stationary contact lead-out end 111c to form a path.

[0145] like Figure 12 As illustrated, when the moving contact assembly 12 moves upward to the first position, the first upper moving contact 121 can connect the first stationary contact lead-out end 111a and the fourth stationary contact lead-out end 111d to form a first path. At the same time, the second upper moving contact 122 can connect the second stationary contact lead-out end 111b and the third stationary contact lead-out end 111c to form a second path.

[0146] like Figure 13As illustrated, when the moving contact assembly 12 moves downward to the second position, the first upper moving contact 121 and the second upper moving contact 122 separate from the upper stationary contact lead-out end 111, and the lower moving contact 123 can connect the third stationary contact lead-out end 111c and the fourth stationary contact lead-out end 111d to form a path.

[0147] It should be noted that, in the above Figure 10 and Figure 12 In the illustrated relay, when the moving contact assembly 12 moves upward to the first position, either the first upper moving contact 121 or the second upper moving contact 122 can directly or indirectly connect the corresponding two stationary contact leads 111. Taking the first upper moving contact 121 as an example, direct connection means that the stationary contact lead connected to the stationary contact bracket can extend from the through hole on the stationary contact bracket, and both ends of the first upper moving contact 121 directly contact the corresponding stationary contact lead 111. Indirect connection means that one end of the first upper moving contact 121 contacts the corresponding stationary contact bracket, and the other end contacts the other stationary contact lead 111, thereby indirectly connecting the two stationary contact leads 111. Optionally, refer to... Figure 3 , Figure 14 and Figure 15 The moving contact assembly 12 further includes an elastic component 124;

[0148] Along the direction of movement of the pushing component 10, the elastic component 124 is disposed between the first upper movable contact 121 and the second upper movable contact 122 located on the upper layer and the lower movable contact 123 located on the lower layer.

[0149] Specifically, in one implementation, combined with Figure 3 As illustrated in the illustration, in the relay of this application embodiment, the moving contact assembly 12 may further include an elastic component 124. The elastic component 124 is not limited to a compression spring or a spring with elasticity. The elastic component 124 is disposed between the upper and lower moving contact pieces. The elastic force generated forces the upper and lower moving contact pieces to tend to move away from each other. When the moving contact assembly 12 moves to the first position, the elastic component 124 is further compressed, increasing the contact pressure between the first upper moving contact piece 121, the second upper moving contact piece 122 and the stationary contact support. When the moving contact assembly 12 moves to the second position, the elastic component 124 is further compressed, increasing the contact pressure between the lower moving contact piece 122 and the stationary contact support. This ensures that the path formed by the stationary contact lead-out end 111 is stable and reliable. Figure 14 This diagram illustrates the action of the elastic component 124 on the second upper movable contact 122. Figure 15A schematic diagram of the elastic component 124 acting on the lower movable contact 123 is shown. Specifically, since the first upper movable contact 121 and the second upper movable contact 122 are spaced apart from each other, a set of elastic components 124 is provided between the first upper movable contact 121 and the lower movable contact 123 below it, and another set of elastic components 124 is provided between the second upper movable contact 122 and the lower movable contact 123 below it. The two sets of elastic components 124 can respectively ensure that the first upper movable contact 121 and the second upper movable contact 122 are in tight and reliable contact with the stationary contact support. Of course, in some embodiments, the elastic component 124 can also be a single unit, simultaneously providing elastic preload to the first upper movable contact 121 and the second upper movable contact 122 to increase the contact pressure.

[0150] Optionally, refer to Figure 2 or Figure 11 or Figure 13 At least one of the first upper movable contact 121, the second upper movable contact 122, and the lower movable contact 123 includes at least two sub-movable contacts arranged in parallel.

[0151] Specifically, such as Figure 2 or Figure 11 or Figure 13 As shown, in the relay of this application embodiment, whether it is the first upper moving contact 121, the second upper moving contact 122, or the lower moving contact 123, any one of the moving contacts 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 is understood that in the relay of this application embodiment, any one of the first upper moving contact 121, the second upper moving contact 122, and the lower moving contact 123 can also be... Figure 12 The schematic shows a single sub-moving contact structure to reduce material consumption.

[0152] Optionally, refer to Figure 16 The relay also includes a first magnetic conductor 13;

[0153] Along the direction of movement of the pushing component 10, the first upper movable contact 121 is provided with a first magnetic conductor 13 on the side close to the stationary contact lead-out end 111, and the lower movable contact 123 is provided with a first magnetic conductor 13 on the side away from the stationary contact lead-out end 111. The first magnetic conductor 13 is used to resist the electric repulsive force between the movable contact and the corresponding stationary contact lead-out end 111.

[0154] Specifically, such as Figure 16As shown in the embodiment of this application, the relay further includes a first magnetic conductor 13, which may include multiple magnetic sheets. Along the Z-direction of movement of the pushing assembly 10, a portion of the first magnetic conductor 13 is mounted on the side of the first upper moving contact 121 near the stationary contact lead-out end 111, and another portion of the first magnetic conductor 13 is mounted on the side of the lower moving contact 123 away from the stationary contact lead-out end 111. Both portions of the first magnetic conductor 13 remain stationary. When the moving contact assembly 12 moves upward to the first position, the upper first magnetic conductor 13 resists the electro-repulsive force between the first upper moving contact 121, the second upper moving contact 122, and the stationary contact lead-out end 111. When the moving contact assembly 12 moves downward to the second position, the lower first magnetic conductor 13 resists the electro-repulsive force between the lower moving contact 123 and the stationary contact lead-out end 111. Therefore, in the relay of this application embodiment, in both the first position and the second position, the contact tightness between the moving contact and the stationary contact lead-out terminal 111 can be improved by the stationary first magnetic conductor 13, so as to avoid the electric repulsion force caused by the short circuit current from separating the two.

[0155] Optionally, refer to Figure 16 The relay also includes a second magnetic conductor 14;

[0156] Along the direction of movement of the pushing component 10, the first upper movable contact 121 on the side away from the stationary contact lead-out end 111 and the lower movable contact 123 on the side close to the stationary contact lead-out end 111 are both provided with the second magnetic conductor 14.

[0157] The first magnetic conductor 13 and the second magnetic conductor 14 can form a magnetic circuit to resist the electric repulsion between the moving contact and the corresponding stationary contact lead-out terminal 111.

[0158] Specifically, such as Figure 16 As shown in the embodiment of this application, the relay further includes a second magnetic conductor 14. The second magnetic conductor 14 may be a U-shaped magnetic sheet.

[0159] 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 upper moving contact 121 away from the stationary contact lead-out end 111. Thus, when the moving contact assembly 12 moves upward to the first position, 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 hold the moving contact assembly 12 in the first position.

[0160] Along the Z-direction of movement of the push assembly 10, another part of the second magnetic conductor 14 is installed on one side of the stationary contact lead-out end 111 of the lower moving contact piece 123. Thus, when the moving contact assembly 12 moves downward to the second position, the lower 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 hold the moving contact assembly 12 in the second position.

[0161] Therefore, in the relay of this application embodiment, in both the first and second positions, a magnetic circuit can be formed by the first magnetic conductor 13 and the second magnetic conductor 14 to generate a magnetic attraction force along the contact pressure direction, so as to resist the electric repulsion force between the moving contact piece and the corresponding stationary contact lead-out terminal 111.

[0162] Optionally, refer to Figure 17 and Figure 18 The moving contact assembly 12 includes a first moving contact piece 125 and a second moving contact piece 126, both of which are connected to the pushing assembly 10.

[0163] The first movable contact 125 and the second movable contact 126 are spaced apart along a direction perpendicular to the movement direction of the pushing component 10;

[0164] When the moving contact assembly 12 moves to the first position, the first moving contact piece 125 conducts two of the stationary contact lead-out ends 111 to form a path, and the second moving contact piece 126 conducts the other two of the stationary contact lead-out ends 111 to form another path.

[0165] When the moving contact assembly 12 moves to the second position, the first moving contact piece 125 and the second moving contact piece 126 connect two of the stationary contact lead-out ends 111 to form a path.

[0166] Specifically, in one implementation, combined with Figure 17 and Figure 18 As illustrated, the moving contact assembly 12 in this embodiment can also be an assembly formed by a single layer of moving contact sheet, specifically including a first moving contact sheet 125 and a second moving contact sheet 126.

[0167] The first movable contact 125 and the second movable contact 126 are located on the same layer and are both connected to the push assembly 10. Furthermore, the first movable contact 125 and the second movable contact 126 are spaced apart from each other.

[0168] like Figure 17As illustrated, when the moving contact assembly 12 moves upward to the first position, the first moving contact piece 125 can connect the first stationary contact lead-out end 111a and the second stationary contact lead-out end 111b to form a first path. At the same time, the second moving contact piece 126 can connect the third stationary contact lead-out end 111c and the fourth stationary contact lead-out end 111d to form a second path.

[0169] like Figure 18 As illustrated, when the moving contact assembly 12 moves downward to the second position, the first moving contact piece 125 and the second moving contact piece 126 separate from the upper stationary contact lead-out end 111. The first moving contact piece 125 and the second moving contact piece 126 can then connect the first stationary contact lead-out end 111a and the third stationary contact lead-out end 111c to form a conductive path. Figures 10 to 13 Compared to the illustrated double-layer moving contact structure, Figure 17 and Figure 18 The schematic single-layer moving contact helps reduce the size of the relay in the Z direction, which is beneficial for the miniaturization of the relay.

[0170] Optionally, refer to Figure 19 At least one of the first movable contact piece 125 and the second movable contact piece 126 includes no less than two sub-movable contact pieces arranged in parallel.

[0171] Specifically, such as Figure 19 As shown, in the relay of this application embodiment, either the first moving contact 125 or the second moving contact 126 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 is understood that in the relay of this application embodiment, either the first moving contact 125 or the second moving contact 126 can also be... Figure 18 The schematic shows a single sub-moving contact structure to reduce material consumption.

[0172] Optionally, the relay further includes a first magnetic conductor 13;

[0173] Along the direction of movement of the pushing component 10, the first moving contact 125 near the stationary contact lead-out end 111 and the second moving contact 126 near the stationary contact lead-out end 111 are both provided with the first magnetic conductor 13. 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.

[0174] Specifically, in the relay of this application embodiment, similar to the double-layer moving contact assembly 12, the magnetism of the first magnetic conductor 13 can also be used to improve the tightness of the contact engagement between the moving contact piece and the stationary contact lead-out end 111 for the single-layer moving contact assembly 12. At this time, along the movement direction Z of the pushing assembly 10, the first magnetic conductor 13 is installed on the side of the first moving contact piece 125 near the stationary contact lead-out end 111, and another part of the first magnetic conductor 13 is installed on the side of the second moving contact piece 126 near the stationary contact lead-out end 111. Both parts of the first magnetic conductor 13 remain stationary. When the moving contact assembly 12 moves upward to the first position, the upper first magnetic conductor 13 can resist the electrodynamic repulsive force between the first moving contact piece 125, the second moving contact piece 126 and the stationary contact lead-out end 111.

[0175] Optionally, the relay further includes a second magnetic conductor 14;

[0176] Along the direction of movement of the pushing component 10, the first moving contact 125 on the side away from the stationary contact lead-out end 111 and the second moving contact 126 on the side away from the stationary contact lead-out end 111 are both provided with the second magnetic conductor 14. The first magnetic conductor 13 and the second magnetic conductor 14 can form a magnetic circuit to resist the electric repulsion between the moving contact and the corresponding stationary contact lead-out end 111.

[0177] Specifically, in the relay of this application embodiment, similar to the double-layer moving contact assembly 12, for the single-layer moving contact assembly 12, the relay may further include a second magnetic conductor 14. The second magnetic conductor 14 may be a U-shaped magnetic sheet. Along the movement direction Z of the pushing assembly 10, a portion of the second magnetic conductor 14 is installed on the side of the first moving contact sheet 125 facing away from the stationary contact lead-out end 111, and another portion of the second magnetic conductor 14 is installed on the side of the second moving contact sheet 126 facing away from the stationary contact lead-out end 111. Thus, when the moving contact assembly 12 moves upward to the first position, the upper first magnetic conductor 13 and the corresponding second magnetic conductor 14 can form a closed magnetic loop, which can more stably and reliably hold the moving contact assembly 12 in the first position.

[0178] Optionally, refer to Figure 2 Each of the stationary contact leads 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;

[0179] Each of the contact portions 1112 is disposed near the moving contact assembly 12 for contacting or disconnecting from the moving contact assembly 12;

[0180] 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.

[0181] Specifically, such as Figure 2 As illustrated, in the relay of this application embodiment, all stationary contact leads 111 can be located at the same end in the direction of movement of the actuating component 10, such as the upper end in the Z direction as shown in the figure. Combined with... Figure 2 As illustrated, each stationary contact lead-out 111, like the fourth stationary contact lead-out 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 top, away from the moving contact assembly 12, and the contact portion 1112 is located at the bottom, 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. Further details on other forms of the load connection portion 1111 are not provided 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 and a stationary contact lead-out end 111 (e.g.) Figure 8 The first stationary contact lead-out terminal 111a) is connected to the contact portion 1112, and the connecting portion 11a of the second stationary contact bracket 113 is connected to another stationary contact lead-out terminal 111 (e.g., ...). Figure 8The contact portion 1112 of the schematic third stationary contact lead-out terminal 111c is connected. At this time, the thickness of the first stationary contact support 112 and the second stationary contact support 113 occupies a portion of the space below the corresponding stationary contact lead-out terminal 111. To ensure that the load connection portions 1111 of each stationary contact lead-out terminal 111 located at the upper part of the B direction are at the same height and their end faces are flush, and to guarantee 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 bracket is larger. This allows the moving contact assembly 12 to move to the first position, so that when a portion of the moving contact assembly 12 moves to the first position, a portion 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 another portion of the moving contact assembly 12 contacts the stationary contact bracket 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 working 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.

[0182] Optionally, when the moving contact assembly 12 moves to the third position, the moving contact assembly 12 is disconnected from any of the stationary contact leads 111.

[0183] Specifically, in one embodiment, the moving contact assembly 12 in the relay of this application can be moved to a third position. This third position is different from the aforementioned first and second positions. In the third position, the moving contact assembly 12 can be disconnected from any stationary contact lead-out terminal 111. In this case, the relay can remain in a disconnected working state and no longer conduct to form any circuit.

[0184] Optionally, refer to Figure 1 The relay further includes a coil 20, and the actuating assembly 10 includes a actuating rod 101;

[0185] 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.

[0186] Specifically, in one embodiment of the relay of this application, 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 shown in the figure, thereby driving the moving contact assembly 12 to move, so that the moving contact assembly 12 moves closer to or away from the stationary contact assembly 11.

[0187] 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.

[0188] 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, the moving iron core is driven by the electromagnetic force of the coil 20, causing the push rod 101 to move linearly along the axis of the coil 20, correspondingly causing the moving contact assembly 12 to move linearly, thereby moving closer to or further away from the stationary contact assembly 11 to achieve relay on / off control.

[0189] Optionally, refer to Figure 11 or Figure 13 When the moving contact assembly 12 moves to the second position, the load current flows from one of the stationary contact leads 111 connected at one end of the moving contact assembly 12 to the other stationary contact lead 111 connected at the other end of the moving contact assembly 12.

[0190] Specifically, in one implementation, such as Figure 11 or Figure 13As illustrated, when the moving contact assembly 12 moves to the second position, one end of the lower moving contact piece 123 overlaps with the overlapping portion 11c of a stationary contact bracket, and the other end of the lower moving contact piece 123 overlaps with the overlapping portion 11c of another stationary contact bracket. Therefore, in this embodiment, current flows from one stationary contact lead-out end to one end of the moving contact assembly 12, and along the length of the moving contact assembly 12 to the other stationary contact lead-out end. That is, a path is formed inside the relay by two overlapping contact relationships at both ends of the moving contact assembly along its length. This results in fewer contact points, lower contact resistance, and a simpler structure, which also facilitates the miniaturization of the relay.

[0191] 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 be connected 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 be connected 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.
