[0017] According to some embodiments of this disclosure, the insulating base is integrally injection molded to the push rod, the plurality of contact supports, and the insulating component.

[0018] According to some embodiments of this disclosure, the movable member further includes an auxiliary movable contact piece, which is connected to the insulating base.

[0019] According to some embodiments of this disclosure, the insulating base is integrally injection molded to the push rod, the plurality of contact supports, the insulating component, and the auxiliary moving contact piece.

[0020] According to some embodiments of this disclosure, the insulating base further includes two covers, which are respectively disposed over the auxiliary moving contacts at both ends of the auxiliary moving contact piece in the longitudinal direction.

[0021] The relays of this disclosure include any of the movable components described above.

[0022] According to some embodiments of this disclosure, the relay further includes a sealed housing, an isolation base, and multiple pairs of stationary contacts. The movable member is movably disposed within the sealed housing. One active contact of the movable member is used to contact or separate from a pair of stationary contacts. The isolation base is disposed within the sealed housing and includes at least one second isolation structure. The second isolation structure is provided between adjacent active contacts.

[0023] According to some embodiments of this disclosure, the second isolation structure includes two second isolation walls, which are spaced apart along the arrangement direction of two adjacent active contact pieces.

This significantly improves the electrical insulation performance between adjacent contact supports, reducing the risk of mutual interference between adjacent active contacts. The insulating base can be made of a cheaper material, saving costs. Furthermore, multiple active contacts are mounted on the same push rod. When the push rod moves, multiple active contacts move simultaneously, achieving a "single-drive, multi-action" effect. This is beneficial for the miniaturization and integration of the relay, while also reducing product costs to a certain extent. Attached Figure Description

[0039] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0040] It is understood that the terms "comprising" and "having," and any variations thereof, used in the embodiments of this disclosure, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to such processes, methods, products, or apparatus.

[0041] As shown in FIG1, the relay of this embodiment includes a sealed housing 100, a movable member 200, and a coil assembly 600. The movable member 200 is movably disposed within the sealed housing 100 and configured to switch the relay from a closed state to an open state and from an open state to a closed state in response to an input signal. The coil assembly 600 is used to drive the movable member 200 to move.

[0042] The sealed housing 100 is provided with a stationary contact 150, and a movable member 200 is used to contact or separate from the stationary contact 150. When the movable member 200 is in contact with the stationary contact 150, the relay is in a closed state. When the movable member 200 is disconnected from the stationary contact 150, the relay is in an open state.

[0043] The sealed housing 100 may include an insulating cover 110, a frame plate 120, a yoke plate 130, and a metal cover 140. The insulating cover 110 and the frame plate 120 are located on one side of the thickness direction of the yoke plate 130, and the metal cover 140 is located on the other side of the thickness direction of the yoke plate 130. A stationary contact 150 is mounted on the insulating cover 110.

[0044] The yoke plate 130 has a first through hole 131 (as shown in Figure 6), which penetrates the yoke plate 130 along its thickness direction and is covered by an insulating cover 110. A movable member 200 is movably inserted through the first through hole 131 of the yoke plate 130.

[0045] In one embodiment, the insulating cover 110 is made of ceramic material and is connected to the yoke plate 130 via a frame plate 120. The frame plate 120 can be a ring-shaped metal part, such as one made of an iron-nickel alloy. One end of the frame plate 120 is connected to the opening edge of the insulating cover 110, for example, by laser welding, brazing, resistance welding, or adhesive bonding. The other end of the frame plate 120 is connected to the yoke plate 130, also by laser welding, brazing, resistance welding, or adhesive bonding. The frame plate 120 is provided between the insulating cover 110 and the yoke plate 130 to facilitate the connection between them.

[0046] The insulating cover 110 includes a top wall 111 and a side wall 112, with the side wall 112 located around the movable member 200. The top wall 111 is equipped with a stationary contact 150. One end of the side wall 112 is connected to the edge of the top wall 111, and the other end of the side wall 112 is connected to the yoke plate 130 via a frame plate 120.

[0047] The sidewall 112 can be a rectangular ring structure, a circular ring structure, or a ring structure of other shapes, and this disclosure does not make any special limitation in this regard.

[0048] As shown in Figure 1, multiple pairs of stationary contacts 150 are installed on the top wall 111 of the insulating cover 110. Each pair of stationary contacts 150 can be electrically connected to an external conductive circuit, enabling the relay to control multiple external conductive circuits simultaneously. In this way, one relay can control multiple conductive circuits at the same time, simplifying the number of electronic devices in the control circuit and facilitating miniaturization.

[0049] It is understood that the relays in the embodiments of this disclosure may include two pairs, three pairs, four pairs or other numbers of stationary contacts 150, and this disclosure does not make any particular limitation in this regard.

[0050] Furthermore, for ease of explanation, the arrangement direction of the two stationary contacts 150 in pairs is defined as the first direction D1, the movement direction of the movable member 200 is defined as the second direction D2, the first direction D1 is perpendicular to the second direction D2, and the direction that is perpendicular to both the first direction D1 and the second direction D2 is defined as the third direction D3, that is, the first direction D1, the second direction D2 and the third direction D3 are perpendicular to each other.

[0051] Among them, multiple pairs of stationary contacts 150 are arranged at intervals along the third direction D3.

[0052] As shown in Figures 2 to 4, the movable component 200 includes a push rod 210, an insulating base 220, multiple contact supports 230, multiple active contact pieces 240, and an insulating element 250. The multiple active contact pieces 240 are arranged along a third direction D3 and are used to contact or separate from multiple pairs of stationary contacts 150 respectively. Each active contact piece 240 can contact or separate from two pairs of stationary contacts 150. One active contact piece 240 and a pair of stationary contacts 150 constitute a contact assembly. When the active contact piece 240 is in contact with the stationary contacts 150, the relay is in a closed state; when the active contact piece 240 is separated from the stationary contacts 150, the relay is in an open state. Multiple active contact pieces 240 are respectively disposed within multiple contact supports 230. The push rod 210, the multiple contact supports 230, and the insulating element 250 are connected by an insulating base 220 to form an integral unit. The multiple contact supports 230 are arranged at intervals along a third direction D3, and each contact support 230 is in contact with the insulating element 250. The insulating element 250 and the insulating base 220 are made of different materials.

[0053] The movable component 200 of this embodiment has multiple contact supports 230 arranged at intervals, and each contact support 230 is in contact with an insulating component 250. Since the insulating component 250 and the insulating base 220 are made of different materials, the insulating component 250 can be made of a material with better electrical insulation performance, heat resistance, and mechanical strength, thereby achieving better insulation and support effects. As a result, the electrical insulation performance between adjacent contact supports 230 is significantly improved, thereby reducing the risk of mutual interference between adjacent active contacts 240. The insulating base 220 can be made of a cheaper material, saving costs. In addition, multiple active contacts 240 are mounted on the same push rod 210. When the push rod 210 moves, multiple active contacts 240 move simultaneously, thereby achieving the effect of "single-drive multiple-action", which is conducive to the miniaturization and integration of the relay size, and at the same time reduces the product cost to a certain extent.

[0054] In one embodiment, the insulating element 250 is made of ceramic material. On the one hand, ceramic material has good insulation properties, which can further improve the electrical insulation performance between adjacent contact supports 230; on the other hand, ceramic material has high strength, which helps to improve the structural strength of the insulating base 220 after the insulating element 250 is connected to the insulating base 220.

[0055] Of course, in other embodiments, the insulating element 250 may also be made of plastic or other insulating materials. For example, the insulating element 250 may also be made of bakelite. Bakelite is chemically known as phenolic plastic, which has high mechanical strength, good insulation, heat resistance, and corrosion resistance.

[0056] In another embodiment, the insulating element 250 may also be made of polyimide, or the insulating element 250 may be made of other materials with excellent high temperature resistance, electrical insulation and mechanical strength.

[0057] As shown in Figure 3, the insulating component 250 has a plate-like structure, and multiple contact supports 230 are in contact with the same side surface of the insulating component 250 in the thickness direction.

[0058] In this embodiment of the present disclosure, multiple contact supports 230 are located on the same side of the thickness direction of the insulating member 250 and are all in contact with the insulating member 250. In this way, the insulating member 250 can serve as an installation reference, thereby improving the installation accuracy of the multiple contact supports 230, ensuring the consistency of the height of the multiple contact supports 230, and ensuring that the multiple active contact pieces 240 and multiple pairs of stationary contacts 150 are simultaneously in contact or disconnected.

[0059] As shown in Figures 2 to 4, the contact support 230 has a base plate 231 and two side plates 232. The base plate 231 is attached to one side surface of the insulating member 250 in the thickness direction. The two side plates 232 are respectively connected to both ends of the base plate 231 along the third direction D3 and extend from the base plate 231 toward the side opposite to the insulating member 250. In the embodiment of this disclosure, the base plate 231 and the two side plates 232 form a U-shape.

[0060] An active contact piece 240 is provided between the two side plates 232.

[0061] The contact support 230 also has a fixing plate 233 (as shown in Figure 1), with both ends of the fixing plate 233 connected to the ends of the two side plates 232 away from the base plate 231. The active contact piece 240 is disposed within the space enclosed by the base plate 231, the two side plates 232 and the fixing plate 233.

[0062] Please refer back to Figure 1. The movable component 200 also includes a plurality of elastic elements 260, which are located in a plurality of contact supports 230. The elastic elements 260 are used to provide contact pressure to the corresponding active contact piece 240.

[0063] In one embodiment, the elastic element 260 is a spring, but it is not limited thereto.

[0064] As shown in Figures 4 and 5, the substrate 231 has a first via 2311, which penetrates the substrate 231 along its thickness direction. The insulating member 250 has a second via 251 corresponding to the position of the first via 2311, which penetrates the insulating member 250 along its thickness direction.

[0065] The insulating base 220 has a protrusion 221 that passes through the first through hole 2311 and the second through hole 251, and simultaneously presses against the opening of the first through hole 2311 on the side away from the insulating member 250 and the opening of the second through hole 251 on the side facing the substrate 231.

[0066] The portion of the protrusion 221 extending out of the side surface of the substrate 231 facing away from the insulating member 250 forms a limiting protrusion 222, which is used to limit the elastic member 260.

[0067] As an example, when the elastic element 260 is a compression spring, one end of the elastic element 260 abuts against the active contact piece 240, and the other end abuts against the substrate 231. Furthermore, the limiting protrusion 222 extends into the compression spring.

[0068] As shown in Figure 4, the insulating base 220 has a first isolation structure 223, and the first isolation structure 223 is provided between adjacent contact supports 230.

[0069] In this embodiment of the present disclosure, the first isolation structure 223 can serve to insulate and isolate adjacent contact supports 230, thereby preventing adjacent contact supports 230 from affecting each other.

[0070] In one embodiment, the first isolation structure 223 includes two first isolation walls 2231, which are spaced apart along the arrangement direction (third direction D3) of the plurality of contact supports 230. The surfaces of the two first isolation walls 2231 facing each other and / or facing away from each other are provided with raised ribs 2232. For example, in one embodiment, the surfaces of the two first isolation walls 2231 facing each other are provided with raised ribs 2232; in another embodiment, the surfaces of the two first isolation walls 2231 facing away from each other are provided with raised ribs 2232.

[0071] In this embodiment of the present disclosure, there is a gap between the two first isolation walls 2231, and the first isolation wall 2231 has a protruding rib 2232, which increases the electrical clearance and creepage distance between adjacent contact supports 230, thereby improving safety.

[0072] As shown in Figures 3 and 4, the insulating member 250 has a first through hole 252, which penetrates the insulating member 250 along its thickness direction. The push rod 210 passes through the first through hole 252.

[0073] As shown in Figure 4, the movable component 200 also includes an auxiliary movable contact 270, which is connected to the insulating base 220. The auxiliary movable contact 270 is used to contact or separate from the auxiliary stationary component 400 (as shown in Figure 1) and to monitor the contact status between the active contact 240 and the stationary contact 150.

[0074] The auxiliary movable contact 270 has a second through hole 271, which extends through the auxiliary movable contact 270 along its thickness direction. The push rod 210 passes through the second through hole 271.

[0075] The insulating base 220 also includes two covers 224, which are respectively provided over the auxiliary moving contacts 272 at both ends of the auxiliary moving contact 270 along its length. Since the auxiliary moving contacts 272 of the auxiliary moving contact 270 are covered by the covers 224, the risk of contamination of the auxiliary moving contacts 272 by the electric arc generated during the contact and separation of the active contact 240 and the stationary contact 150 is reduced.

[0076] In one embodiment, the insulating base 220 is made of plastic material and is connected to the push rod 210, multiple contact brackets 230, insulating component 250, and auxiliary moving contact piece 270 by integral injection molding.

[0077] In this embodiment of the disclosure, multiple parts of the movable component 200 are connected by an integral injection molding method, which simplifies the number of parts in the movable component 200, reduces costs, and reduces assembly steps. At the same time, the push rod 210 and the auxiliary movable contact 270 are integrally injection molded, which reduces the dimensional chain between parts, makes dimensional accuracy easier to control, and ensures the consistency of movement between the main contact and the auxiliary contact.

[0078] In one embodiment, the connection process of the insulating base 220, the push rod 210, the multiple contact supports 230, the insulating component 250, and the auxiliary moving contact 270 can be completed in two stages. Specifically, in the first injection molding process, the insulating base 220 connects the push rod 210, the multiple contact supports 230, and the insulating component 250 through an integral injection molding connection, forming an intermediate injection molded part. In the second injection molding process, the intermediate injection molded part is connected to the auxiliary moving contact 270 through injection molding.

[0079] As shown in Figures 6 and 7, the relay also includes an isolating base 300, which is disposed within the sealed housing 100. In this embodiment of the present disclosure, the isolating base 300 is located within the insulating cover 110 and is attached to the side surface of the yoke plate 130 facing the insulating cover 110.

[0080] The isolation base 300 includes at least one second isolation structure 310 and a base 320. The base 320 is attached to the side surface of the yoke plate 130 facing the insulating cover 110. The second isolation structure 310 is connected to the base 320. The second isolation structure 310 is provided between adjacent active contact pieces 240.

[0081] In this embodiment of the present disclosure, the isolation base 300 includes at least one second isolation structure 310. The second isolation structure 310 is provided between adjacent active contact pieces 240. The second isolation structure 310 can insulate and isolate adjacent active contact pieces 240, so as to prevent adjacent active contact pieces 240 from affecting each other when the active contact pieces 240 are energized.

[0082] In one embodiment, the isolation seat 300 is supported by an insulating material, such as plastic, ceramic, etc.

[0083] As shown in Figure 6, the second isolation structure 310 includes two second isolation walls 311, which are spaced apart along the arrangement direction (third direction D3) of the two adjacent active contact pieces 240.

[0084] In this embodiment of the present disclosure, there are two second isolation walls 311 between two adjacent active contact pieces 240, and there is a gap between the two second isolation walls 311, which increases the creepage distance between adjacent active contact pieces 240 and further reduces the risk of mutual interference between adjacent active contact pieces 240.

[0085] The second isolation wall 311 has two sub-walls 3111, which are spaced apart along the arrangement direction (first direction D1) of the pair of stationary contacts 150. The two sub-walls 3111 are respectively located on the side of the two stationary contacts 150 of one contact assembly facing the two stationary contacts 150 of the other contact assembly.

[0086] For example, taking two contact components as an example, the two contact components have a total of four stationary contacts 150, and the two stationary contacts 150 of each contact component are arranged along the first direction D1. Along the third direction D3, the two stationary contacts 150 of one contact component correspond to the positions of the two stationary contacts 150 of the other contact component. On the third direction D3, two sub-walls 3111 are provided between the corresponding two stationary contacts 150.

[0087] As shown in Figure 7, the base 320 has a second through hole 321 corresponding to the position of the first through hole 131, and the movable member 200 is movably inserted into the second through hole 321.

[0088] In summary, the relays of the present disclosure embodiments have at least the following advantages and beneficial effects:

[0089] The movable component 200 of this embodiment has multiple contact supports 230 arranged at intervals, and each contact support 230 is in contact with an insulating component 250. Since the insulating component 250 and the insulating base 220 are made of different materials, the insulating component 250 can be made of a material with better electrical insulation performance, heat resistance, and mechanical strength, thereby achieving better insulation and support effects. As a result, the electrical insulation performance between adjacent contact supports 230 is significantly improved, thereby reducing the risk of mutual interference between adjacent active contacts 240. The insulating base 220 can be made of a cheaper material, saving costs. In addition, multiple active contacts 240 are mounted on the same push rod 210. When the push rod 210 moves, multiple active contacts 240 move simultaneously, thereby achieving the effect of "single-drive multiple-action", which is conducive to the miniaturization and integration of the relay size, and at the same time reduces the product cost to a certain extent.
