Description

Technical Field

[0001] The present disclosure relates to a relay and a device. Background Art

[0002] A relay is an electronic control device that has a control system (also known as an input circuit) and a controlled system (also known as an output circuit). Relays are usually used in automatic control circuits. In fact, they are an "automatic switch" that uses a smaller current to control a larger current. Therefore, relays can play a role in automatic regulation, safety protection, and circuit conversion in the circuit.

[0003] A high-voltage DC relay is a type of relay. In existing designs of high-voltage DC relays, when the relay adopts a multi-connection structure, that is, the relay has multiple functional modules, multiple auxiliary contact assemblies of the multiple functional modules are correspondingly arranged with auxiliary lead-out assemblies, and each auxiliary lead-out assembly has a lead-out pin extending out of the housing, resulting in a larger space occupied by the auxiliary lead-out assembly, which is not conducive to the client's installation of other components.

Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of the present disclosure.

In this exemplary embodiment, the relay proposed in the present disclosure is described by taking a double-structured relay as an example. It is easy for those skilled in the art to understand that in order to apply the relevant design of the present disclosure to other types of relays, various modifications, additions, substitutions, deletions or other changes are made to the specific embodiments described below, and these changes are still within the scope of the principle of the relay proposed in the present disclosure.

[0071] like Figure 1 As shown, in one embodiment of the present disclosure, the relay provided by the present disclosure includes a housing 100, at least two functional modules 200 and at least one combined lead structure 300. The following embodiment takes a double-structured relay as an example, that is, it includes two functional modules 200. Figures 2 to 10 , Figure 2, which is a three-dimensional schematic diagram of a partial structure of a relay, specifically shows a combined structure of two functional modules 200; Figure 3 A representative example is shown in Figure 2 Bottom view of Figure 4 A representative example is shown in Figure 2 A schematic diagram of a three-dimensional structure of a partial structure shown; Figure 5 , a three-dimensional structural schematic diagram of the combined structure of the second component 320 and the U-shaped yoke 221 is representatively shown;

Figure 8 , a three-dimensional structural schematic diagram of a part of the structure of the first component 310 is representatively shown, wherein the insulating member 303 of the first component 310 is specifically hidden; Fig. 9 A three-dimensional structural schematic diagram of the second component 320 is representatively shown in FIG. Fig.10 The 3D schematic diagram of the partial structure of the second component 320 is representatively shown in FIG. 3, wherein the insulating member 303 of the second component is specifically hidden. The structure, connection mode and functional relationship of each main component of the relay proposed in the present disclosure will be described in detail below in conjunction with the above drawings.

[0073] like Figures 1 to 4 and Figure 6As shown, in one embodiment of the present disclosure, the functional module 200 is partially disposed in the housing 100, each functional module 200 includes an auxiliary contact component, and each auxiliary contact component includes an auxiliary lead-out component. The combined lead-out structure 300 includes at least two auxiliary lead-out components, and these auxiliary lead-out components all belong to auxiliary lead-out components of different functional modules 200, that is, the combined lead-out structure 300 is composed of at least two auxiliary lead-out components respectively belonging to different functional modules 200, that is, two or more auxiliary lead-out components of the auxiliary lead-out components of the same functional module 200 do not constitute the same combined lead-out structure 300. Among them, taking the combined lead-out structure 300 composed of two auxiliary lead-out components as an example, the two auxiliary lead-out components are respectively the first component 310 and the second component 320, and each end of the two auxiliary lead-out components is respectively used to participate in the connection or disconnection of the auxiliary contact components of the two functional modules. The other end of the first component 310 extends out of the housing 100, and the other end of the second component 320 is directly connected to the first component 310, so that the portion of the first component 310 extending out of the housing 100 serves as the common lead pin 330 of the combined lead structure 300. Through the above design, the present disclosure can lead out at least two auxiliary lead components of the combined lead structure 300 using a common lead pin 330, thereby reducing the number of lead pins of the auxiliary lead structure, thereby reducing the space occupied by the auxiliary lead structure, and facilitating the installation of other components by the client.

[0074] It should be noted that the so-called "functional module 200" in this specification refers to the contact components included in each functional module 200 being driven by an independent magnetic circuit part. Taking the main contact component as an example, the main contact component includes a main static contact 210 and an active spring component. For a main contact component, as long as the active contact piece is driven by the same magnetic circuit part to move together and contact or separate with each main static contact 210, the mechanism formed by the contact part (including the main contact component and the corresponding auxiliary contact component) and the magnetic circuit part is the functional module 200. In other words, for a functional module 200, active contacts are respectively provided at both ends of the active contact piece, and the main contact component of a functional module 200 includes two main static contacts 210, or the main contact component of a functional module 200 may include one, two or more active contacts, and include main static contacts 210 with corresponding positions, and these active contacts are all driven by the same magnetic circuit part to move together. On this basis, the relay proposed in the present disclosure includes at least two of the above-mentioned functional modules 200 , that is, the contact actions of these functional modules 200 are relatively independent.

[0075] It should be noted that, in this embodiment, the combined lead-out structure 300 includes a first component 310 and a second component 320. In some embodiments, the combined lead-out structure 300 may also include at least two second components 320. For example, when the combined lead-out structure 300 includes three auxiliary lead-out components, the three auxiliary lead-out components may be a first component 310 and two second components 320. At this time, the two second components 320 may be connected to the first component 310, respectively, or the first second component 320 is connected to the first component 310, and the second second component 320 is connected to the first second component 320, thereby indirectly connected to the first component 310. For another example, when the combined lead-out structure includes four auxiliary lead-out components, the three auxiliary lead-out components can be a first component 310 and three second components 320. At this time, the three second components 320 can be connected to the first component 310 respectively, or the three second components 320 can be connected to the first component 310 in sequence, that is, the first second component 320 is connected to the first component 310, the second second component 320 is connected to the first second component 320, thereby indirectly connected to the first component 310, and the third second component 320 is connected to the second second component 320, thereby indirectly connected to the first component 310, or the third second component 320 can be connected to the first component 310, all of which are not limited to the above embodiments. In other words, in various possible embodiments consistent with the design concept of the present disclosure, for at least one combined lead-out structure 300, it includes at least one second component 320, and the other end of the second component 320 is connected to the first component 310, or is indirectly connected to the first component 310 via connection with other second components 320.

[0076] like Figure 6As shown, in one embodiment of the present disclosure, two auxiliary lead-out components belonging to the same combined lead-out structure 300 may at least adopt the following identical structural design: for example, the auxiliary lead-out component may include a first conductive member 301 and a second conductive member 302, the above-mentioned contact is provided at one end of the first conductive member 301, and the second conductive member 302 has a conductive body connected to the other end of the first conductive member 301. On this basis, the two auxiliary lead-out components belonging to the same combined lead-out structure 300 may at least adopt the following different structural designs: for example, the second conductive member 302 of the first component 310 further has a lead-out portion 311 and a first connecting portion 312, one end of the lead-out portion 311 is connected to the conductive body, the other end of the lead-out portion 311 extends out of the housing 100 and serves as a common lead-out pin 330 of the combined lead-out structure 300, and the first connecting portion 312 is connected to the conductive body of the first component 310. For another example, the second conductive member 302 of the second component 320 further has a second connection portion 322, which is connected to the conductive body of the second component 320, and the second component 320 is directly connected to the first connection portion 312 of the first component 310 via the second connection portion 322, or is indirectly connected to the first connection portion 312 via the second connection portion 322 of other second components 320.

[0077] like Figures 6 to 10 As shown, based on the structural design that the first component 310 has a first connection part 312 and the second component 320 has a second connection part 322, in one embodiment of the present disclosure, the first connection part 312 can be provided with a first electrical connection jack 3121, and the second connection part 322 can be provided with a first pin structure 3221, accordingly, the first pin structure 3221 is plugged into the first electrical connection jack 3121, so as to realize the mutual connection of the second conductive members 302 of the two auxiliary lead-out components belonging to the same combined lead-out structure 300. In some embodiments, a pin structure can also be provided on the first connection part 312, and an electrical connection jack can be provided on the second connection part 322, which is not limited to this embodiment.

[0078] like Figures 6 to 10 As shown, based on the structural design that the auxiliary lead-out component includes the second conductive member 302, in one embodiment of the present disclosure, the auxiliary lead-out component may further include an insulating member 303, and the insulating member 303 covers the conductive body of the second conductive member 302. In addition, the lead-out portion 311 and the first connecting portion 312 of the first component 310 are at least partially exposed outside the insulating member 303 of the first component 310, and the second connecting portion 322 of the second component 320 is at least partially exposed outside the insulating member 303 of the second component 320. Through the above design, the present disclosure can further optimize the insulation performance of the auxiliary lead-out component by using the insulating member 303.

[0079] like Figures 5 to 7 and Fig. 9 As shown, based on the structural design that the auxiliary lead-out component includes an insulating member 303, in one embodiment of the present disclosure, the insulating member 303 may be provided with a positioning structure, and the positioning structure is used to achieve the relative positioning of the auxiliary lead-out component and the functional module 200. Through the above design, the present disclosure can use the positioning structure to position the auxiliary lead-out component, thereby improving the structural stability and reliability of the low-voltage lead-out part.

[0080] like Figure 2 , Figures 4 to 7 and Fig. 9 As shown, based on the structural design of the positioning structure provided on the insulating member 303, in one embodiment of the present disclosure, the functional module 200 also includes a magnetic circuit part, and the magnetic circuit part includes a yoke assembly, a coil assembly and an iron core assembly (not shown in the drawings). The yoke assembly includes a U-shaped yoke 221 and a yoke plate, and the U-shaped yoke 221 has a connecting portion 2211 and two side portions 2212, and the two side portions 2212 are arranged at intervals and respectively connected to the two ends of the connecting portion 2211, and the two side portions 2212 are respectively connected to the yoke plate at one end away from the connecting portion 2211. The coil assembly is located in the accommodation space formed between the U-shaped yoke 221 and the yoke plate, and the coil assembly includes a coil frame and a coil wound on the coil frame.

[0081] The core assembly is accommodated in the through hole of the coil frame, and the core assembly includes a static core and a moving core arranged along the first direction X. Accordingly, when a certain voltage is applied to both ends of the coil, a certain current flows through the coil, thereby generating an electromagnetic effect, thereby driving the moving core to move relative to the static core, and driving the moving contact piece to move so that the moving contact of the moving contact piece contacts the static contact. When the coil is powered off, the electromagnetic suction force disappears, and the moving core returns to its original position under the elastic restoring force of the elastic member, thereby driving the moving contact piece to move so that the moving contact of the moving contact piece is separated from the static contact. On this basis, the positioning structure of the insulating member 303 can at least include a positioning slot 3031, and the positioning slot 3031 is used for the connection portion 2211 of the U-shaped yoke 221 to engage and position. Through the above design, the present invention can achieve the relative positioning of the auxiliary lead-out component and the U-shaped yoke 221, thereby making the positioning of the low-voltage lead-out part more convenient and reliable, and at the same time is conducive to the arrangement of the low-voltage lead-out part on the side of the U-shaped yoke 221, which can further reduce the difficulty of arranging the low-voltage lead-out part and reduce its space occupancy in the relay.

[0082] In addition, the iron core assembly is accommodated in the through hole of the coil frame, and the iron core assembly includes a static iron core and a moving iron core arranged along the first direction X. Accordingly, when a certain voltage is applied to both ends of the coil, a certain current flows through the coil, thereby generating an electromagnetic effect, thereby driving the moving iron core to move relative to the static iron core, and driving the active contact piece to move so that the active contact piece contacts the main static contact. When the coil is powered off, the electromagnetic suction force disappears, and the moving iron core returns to its original position under the elastic restoring force of the elastic member, thereby driving the active contact piece to move so that the active contact piece is separated from the main static contact.

[0083] like Figure 6 , Figure 7 and Fig. 9 As shown, based on the structural design of the positioning structure of the insulating member 303 including the positioning slot 3031, in one embodiment of the present disclosure, the insulating member 303 can be provided with two positioning protrusions 3032, the positioning protrusion 3032 extends from the insulating member 303 toward one side of the connecting portion 2211, and extends in a direction parallel to the connecting portion 2211, and the two positioning protrusions 3032 are arranged at intervals up and down, and the above-mentioned positioning slot 3031 is formed between the two positioning protrusions 3032.

Through the above design, the present disclosure can further strengthen the structural strength between the insulating member 303 and the positioning protrusion 3032 by using the reinforcing rib plate 3033.

[0085] like Figure 7 As shown, based on the structural design that the first connection part 312 of the first component 310 is provided with a first electrical connection jack 3121 and the second connection part 322 of the second component 320 is provided with a first pin structure 3221, in one embodiment of the present disclosure, the region of the insulating member 303 corresponding to the first electrical connection jack 3121 may be provided with a first avoidance hole 3034, and the aperture of the first avoidance hole 3034 may be larger than the aperture of the first electrical connection jack 3121, thereby completely exposing the first electrical connection jack 3121. Through the above design, the present disclosure can avoid the insulating member 303 from shielding the first electrical connection jack 3121, and ensure the connection reliability and stability of the two auxiliary lead-out components belonging to the same combined lead-out structure 300.

[0086] like Fig. 9As shown, based on the structural design that the auxiliary lead-out component includes the first conductive member 301 and the second conductive member 302, in one embodiment of the present disclosure, the other end of the first conductive member 301 may be provided with a second pin structure 3011, and the conductive body of the second conductive member 302 may be provided with a second electrical connection plug hole 30211, and the second pin structure 3011 is plugged into the second electrical connection plug hole 30211, so as to realize the connection between the first conductive member 301 and the second conductive member 302. On this basis, the insulating member 303 may be provided with a second avoidance hole 3035 in the area corresponding to the second electrical connection plug hole 30211, and the aperture of the second avoidance hole 3035 may be larger than the aperture of the second electrical connection plug hole 30211, thereby completely exposing the second electrical connection plug hole 30211. Through the above design, the present disclosure can avoid the insulating member 303 from blocking the second electrical connection plug hole 30211, and ensure the reliability and stability of the connection between the first conductive member 301 and the second conductive member 302 belonging to the same auxiliary lead-out component.

[0087] like Fig. 9 and Fig.10 As shown, based on the structural design that the auxiliary lead-out assembly includes an insulating member 303, in one embodiment of the present disclosure, the conductive body can be provided with a weight-reducing hole 30212, and the insulating member 303 also covers the hole wall of the weight-reducing hole 30212 and occupies part of the hole of the weight-reducing hole 30212. Through the above design, the present disclosure can use the weight-reducing hole 30212 to reduce the weight of the conductive body, which is conducive to the lightweight design of the relay. In addition, by covering the hole wall of the weight-reducing hole 30212 with the insulating member 303, the present disclosure can ensure the insulation effect of the conductive body with the weight-reducing hole 30212.

[0088] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment of the present disclosure, the relay proposed in the present disclosure also includes at least two independent lead-out structures 400, each of which is composed of a single auxiliary lead-out component, one end of the independent lead-out structure 400 is used to participate in the connection or disconnection of the auxiliary contact component, and the other end of the independent lead-out structure extends out of the housing 100.

[0089] In one embodiment of the present disclosure, the auxiliary contact assembly of the functional module 200 includes an auxiliary spring assembly. Among them, each end of at least two auxiliary lead-out assemblies belonging to a combined lead-out structure contacts or separates with the auxiliary spring assemblies of at least two functional modules 200 respectively. For example, the auxiliary spring assembly may include an auxiliary moving contact piece, and the auxiliary moving contact piece is provided with an auxiliary moving contact point. The auxiliary moving contact point can be provided on the auxiliary moving contact piece by means of, for example, riveting, or can be an integral structure with the auxiliary moving contact piece. On this basis, the above-mentioned auxiliary lead-out assembly can be a lead-out structure connected to the auxiliary moving contact piece, one end of which is connected to the auxiliary moving contact piece, and the other end extends out of the housing 100 and serves as a lead-out pin of the auxiliary moving contact piece. Alternatively, the above-mentioned auxiliary lead-out assembly can also be provided with an auxiliary static contact point at one end thereof, so as to contact or separate with the auxiliary moving contact point of the auxiliary moving contact piece accordingly, and the auxiliary lead-out assembly serves as a lead-out structure of the auxiliary static contact point. In other embodiments of the present disclosure, the auxiliary lead-out component may also be a lead-out structure of an auxiliary moving contact piece and a lead-out structure of an auxiliary static contact, and is not limited to the above embodiments.

[0090] It should be noted that, taking the auxiliary contact assembly of a functional module 200 as an example, the auxiliary contact assembly includes an auxiliary spring assembly, the auxiliary spring assembly includes an auxiliary moving contact piece, and auxiliary moving contacts are respectively provided at both ends of the auxiliary moving contact piece. In this case, the auxiliary contact assembly includes two auxiliary lead-out assemblies, and auxiliary static contacts are provided at each end of the two auxiliary lead-out assemblies. The two auxiliary static contacts are respectively in contact with or separated from the two auxiliary moving contacts. Alternatively, the auxiliary contact assembly includes an auxiliary spring assembly and an auxiliary static spring assembly, the auxiliary spring assembly includes an auxiliary moving contact piece, and an auxiliary moving contact is provided at one end of the auxiliary moving contact piece. In this case, the auxiliary contact assembly includes two auxiliary lead-out assemblies, one of which is connected to an auxiliary moving contact piece, and an auxiliary static contact is provided at one end of the other auxiliary lead-out assembly. The auxiliary static contact is respectively in contact with or separated from the auxiliary moving contact. In other words, the two auxiliary lead-out assemblies are an auxiliary static lead-out structure and an auxiliary moving lead-out structure. To sum up, in various possible implementations consistent with the design concept of the present invention, for the auxiliary lead-out component constituting the combined lead-out structure, it may be an auxiliary moving contact piece connected to the auxiliary contact component to serve as an auxiliary moving lead-out structure, or it may be an auxiliary static contact point provided at one end to serve as an auxiliary static lead-out structure.

[0091] like Figure 1As shown, in one embodiment of the present disclosure, the housing 100 has a first surface and a second surface 101 spaced apart and facing oppositely in a first direction X. For example, the first surface and the second surface 101 can be the top surface and the bottom surface of the housing 100, respectively. The functional module 200 also includes a main contact assembly, which includes a main static contact 210 and an active contact sheet (not shown in the drawings). The active contact sheet is provided with an active contact point. The active contact sheet can contact or separate with the two main static contacts 210. The main static contact 210 extends from the first surface of the housing 100 to the housing 100.

[0092] like Figure 2 As shown, in one embodiment of the present disclosure, the other end of the first component 310 (ie, the common lead pin 330 of the combined lead structure 300) extends out of the housing 100 from the second surface 101 of the housing 100. Figures 1 to 4 As shown, in one embodiment of the present disclosure, each functional module 200 includes two auxiliary static contacts arranged corresponding to the two auxiliary moving contacts of the auxiliary spring assembly. Taking the relay including two functional modules 200 as an example, it is equivalent to the relay including four auxiliary static contacts. On this basis, the relay can include a combined lead-out structure 300 and two independent lead-out structures 400. The combined lead-out structure 300 includes two auxiliary lead-out assemblies, and each end of the two auxiliary lead-out assemblies is used as two auxiliary static contacts and arranged corresponding to each auxiliary moving contact of the two auxiliary spring assemblies. Each end of the two independent lead-out structures 400 contacts or separates with each other auxiliary moving contact of the two auxiliary spring assemblies, and each independent lead-out structure 400 has an independent lead-out pin 410. Accordingly, the four auxiliary static contacts of the relay are led out of the housing 100 via three lead-out pins. In some embodiments, still taking the relay including two functional modules 200 as an example, the relay may also include two combined lead-out structures 300, that is, each end of the two auxiliary lead-out components of one combined lead-out structure 300 is used as an auxiliary static contact and is respectively arranged at each moving contact of the auxiliary spring components of the two functional modules 200, and each end of the two auxiliary lead-out components of the other combined lead-out structure 300 is used as an auxiliary static contact and is respectively arranged at each other moving contact of the auxiliary spring components of the two functional modules 200.

On this basis, each end of the two auxiliary lead-out components of the combined lead-out structure 300 respectively contacts or separates with the two auxiliary moving contacts located on the same side in the third direction Z. Through the above design, the present disclosure selects two auxiliary lead-out components located on the same side in the third direction Z and belonging to the two functional modules 200 respectively to form the combined lead-out structure 300, avoiding the problem that when the two auxiliary lead-out components constituting the combined lead-out structure 300 are located on different sides, a more complicated structure needs to be arranged for connection, which can reduce the difficulty of arranging the combined lead-out structure 300 and the independent lead-out structure 400.

[0094] like Fig.11 As shown, in one embodiment of the present disclosure, the relay provided in the present disclosure further includes a coil lead-out component 231, one end of which is connected to the coil component 230, and the other end of which extends out of the housing 100 as a coil lead-out pin. Further, the other end of the coil lead-out component 230 can extend from the second surface 101 of the housing 100, for example.

[0095] like Fig.12 As shown, the relay proposed in the present disclosure can be connected to the external circuit 500 via the independent lead structure 400, so as to realize the series connection of each functional module 200 of the relay in the external circuit 500. Figures 1 to 4 Taking the illustrated embodiment as an example, that is, when the relay includes a common lead pin 330 (the lead pin of the combined lead structure 300) and two independent lead pins 410, the external circuit 500 can be connected to the two independent lead pins 410 respectively, thereby realizing the series connection of the two functional modules 200 of the relay in the external circuit 500.

[0096] like Fig.13 As shown, the relay proposed in the present disclosure can also be connected to the external circuit 500 via the combined lead structure 300 and the independent lead structure 400, so as to realize the parallel connection of each functional module 200 of the relay in the external circuit 500. Figures 1 to 4 Taking the illustrated embodiment as an example, the external circuit 500 may also be connected to the common lead pin 330 and the two independent lead pins 410 respectively, thereby realizing the parallel connection of the two functional modules 200 of the relay in the external circuit 500 .

[0097] It should be noted that the relays shown in the drawings and described in this specification are only a few examples of the many types of relays that can adopt the principles of the present disclosure.

Through the above design, the present disclosure can lead out at least two auxiliary lead-out components of the combined lead-out structure 300 by sharing a common lead-out pin 330, thereby reducing the number of lead-out pins of the auxiliary lead-out structure, thereby reducing the space occupied by the auxiliary lead-out structure, and facilitating the installation of other components by the client.

Through the above design, the present disclosure can further optimize the insulation performance of the auxiliary lead-out assembly by using the insulating member 303.

[0100] In one embodiment of the present disclosure, the insulating member 303 is provided with a positioning structure, which is used to realize the relative positioning of the auxiliary lead-out assembly and the functional module 200. Through the above design, the present disclosure can use the positioning structure to position the auxiliary lead-out assembly, thereby improving the structural stability and reliability of the low-voltage lead-out part.

[0101] In one embodiment of the present disclosure, the positioning structure includes a positioning slot 3031, which is formed by a positioning protrusion 3032. A reinforcing rib plate 3033 may be connected between the positioning protrusion 3032 and the insulating member 303.

The yoke assembly includes a U-shaped yoke 221 and a yoke plate, and the U-shaped yoke 221 has a connecting portion 2211 and two side portions 2212. The positioning structure of the insulating member 303 includes at least a positioning slot 3031, and the positioning slot 3031 is used for the connection portion 2211 of the U-shaped yoke 221 to engage and position. Through the above design, the present disclosure can achieve the relative positioning of the auxiliary lead-out assembly and the U-shaped yoke 221, thereby making the positioning of the low-voltage lead-out portion more convenient and reliable, and at the same time, it is conducive to the arrangement of the low-voltage lead-out portion on the side of the U-shaped yoke 221, which can further reduce the difficulty of arranging the low-voltage lead-out portion and reduce its space occupancy in the relay.

[0103] In one embodiment of the present disclosure, one end of each of the two auxiliary lead-out components of the combined lead-out structure 300 is respectively used as two auxiliary static contacts located on the same side in the third direction Z. Through the above design, the present disclosure selects two auxiliary lead-out components located on the same side in the third direction Z and belonging to two functional modules 200 to jointly form the combined lead-out structure 300, thereby avoiding the problem that when the two auxiliary lead-out components constituting the combined lead-out structure 300 are located on different sides, a more complicated structure needs to be arranged for connection, and the difficulty of arranging the combined lead-out structure and the independent lead-out structure can be reduced.
