[0036] Typical embodiments that embody the features and advantages of the present disclosure will be described in detail in the following description. It should be understood that the present disclosure can have various changes in different embodiments without departing from the scope of the present disclosure, and the descriptions and drawings therein are essentially for illustrative purposes rather than for limiting the present disclosure.

[0037] In the following description of different exemplary embodiments of the present disclosure, reference is made to the accompanying drawings, which form a part of the present disclosure and in which different exemplary structures, systems and steps that can implement multiple aspects of the present disclosure are shown by way of example. It should be understood that other specific schemes of components, structures, exemplary devices, systems and steps can be used, and structural and functional modifications can be made without departing from the scope of the present disclosure. Moreover, although the terms "above", "between", "within", etc. may be used in this specification to describe different exemplary features and elements of the present disclosure, these terms are used herein only for convenience, such as according to the direction of the examples described in the accompanying drawings. 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.

[0038] See also Figure 1 , which representatively shows a schematic diagram of the three-dimensional structure of the relay proposed in the present disclosure at a viewing angle, wherein the three-dimensional structure of the relay at a relatively inclined top-down viewing angle is specifically shown. 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.

[0039] like Figure 1 As shown, in one embodiment of the present disclosure, the relay provided by the present disclosure includes a housing 100 and at least two functional modules 200. The following embodiments take a double-structured relay as an example, that is, the relay includes two functional modules 200. Figure 2 and Figure 3 , Figure 2 , a schematic diagram of a three-dimensional structure of a relay at another viewing angle is representatively shown, wherein the three-dimensional structure of the relay at a relatively inclined upward viewing angle is specifically shown; Figure 3 The 3D schematic diagram of the partial structure of the relay is representatively shown in FIG. 1 , in which the 3D structure of the relay after the housing 100 is hidden is specifically shown. 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.

[0040] like Figures 1 to 3As shown, in one embodiment of the present disclosure, the functional module 200 is partially disposed in the housing 100. The functional module 200 includes a main contact assembly and a magnetic circuit portion 220, the main contact assembly includes a main static contact 211 and an active spring assembly, the magnetic circuit portion 220 includes a coil assembly, and the coil 221 of the coil assembly is connected to a coil lead-out structure 2211. Accordingly, the main static contact 211 is the high-voltage side lead-out structure of the relay, and the coil lead-out structure 2211 is at least a part of the low-voltage side lead-out structure of the relay. Among them, the main static contact 211 and the coil lead-out structure are respectively led out from the housing 100 on opposite sides of the first direction X. Through the above-mentioned structural design, in the present disclosure, the main static contact 211 and the coil lead-out structure are led out from opposite sides of the housing 100, which can extend the insulation distance between the main static contact 211 and the coil lead-out structure 2211, and improve the insulation performance of the relay.

[0041] In one embodiment not shown in the figure in the present disclosure, the magnetic circuit part 220 includes a yoke assembly, a coil assembly and a core assembly. The yoke assembly includes a U-shaped yoke and a yoke plate, the U-shaped yoke has a connecting portion and two side portions, the two side portions are arranged at intervals and are respectively connected to the two ends of the connecting portion, and one end of each of the two side portions away from the connecting portion is respectively connected to the yoke plate. The coil assembly is located in the accommodation space formed between the U-shaped yoke and the yoke plate, and the coil assembly includes a coil frame and a coil 221 wound around the coil frame. The core assembly is accommodated in the through hole of the coil frame, and the 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 221, a certain current flows through the coil 221, 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 211. When the coil 221 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 part, thereby driving the active contact piece to move so that the active contact piece is separated from the main static contact 211.

[0042] 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 211 and an active spring component. For a main contact component, no matter what form of contact structure (such as a bridge contact structure or a snap-on contact structure) the active contact piece of its active spring component adopts, as long as the components of the active contact piece are driven by the same magnetic circuit part to move together and contact or separate with each main static contact 211, 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, when the active contact piece adopts a bridge contact structure, active contacts can be respectively provided at both ends thereof, and the main contact assembly of a functional module 200 includes two main static contacts 211, or, when the active contact piece adopts a snap-on contact structure, the dynamic spring assembly of the main contact assembly of a functional module 200 can include one, two or more active contacts, and include the same number of main static contacts 211 with corresponding positions, and these active contacts are all driven by the same magnetic circuit part and 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.

[0043] like Figure 3 As shown, in one embodiment of the present disclosure, the main contact assembly and the magnetic circuit portion 220 are arranged along the first direction X. On this basis, the main static contact 211 and the coil lead-out structure 2211 are respectively led out from the opposite sides of the housing 100 in the first direction X, and the coil lead-out structure 2211 is led out from the side of the magnetic circuit portion 220 away from the main contact assembly. Through the above structural design, the present disclosure can shorten the extension distance of the coil lead-out structure 2211 in the housing 100, and reduce the difficulty of arranging the coil lead-out structure 2211 and the main static contact 211.

[0044] like Figure 3 As shown, in one embodiment of the present disclosure, the main contact assembly of the functional module 200 includes at least two main static contacts 211, such as the two main static contacts 211 shown in the accompanying drawings, and correspondingly, the active spring assembly includes an active contact piece, and the two ends of the active contact piece are respectively in contact with or separated from the at least two main static contacts 211. On this basis, the main static contacts 211 of each functional module 200 can be led out from the same side of the housing 100. Through the above-mentioned structural design, the present disclosure can ensure that each main static contact 211 of the relay is led out from the same side of the housing 100, thereby reducing the difficulty of connecting the high-voltage side of the relay with the external circuit.

[0045] like Figure 2As shown, in one embodiment of the present disclosure, for a functional module 200, the coil assembly includes a coil 221, and the functional module 200 includes two coil lead-out structures 2211, and the two coil lead-out structures 2211 are respectively connected to the two ends of the coil 221. On this basis, the coil lead-out structures 2211 of each functional module 200 can all be led out from the same side of the housing 100. Through the above structural design, the present disclosure can ensure that each coil lead-out structure 2211 of the relay is led out from the same side of the housing 100, thereby reducing the difficulty of connecting the low-voltage side of the relay with the external circuit.

[0046] like Figure 2 and Figure 3 As shown, in one embodiment of the present disclosure, the functional module 200 further includes an auxiliary contact assembly, which includes an auxiliary lead-out structure 231, one end of which is led out from the housing 100, and the auxiliary lead-out structure 231 is another part of the low-voltage side lead-out structure of the relay. On this basis, the auxiliary lead-out structure 231 and the main static contact 211 can be led out from different sides of the housing 100, respectively. Through the above structural design, the present disclosure can avoid the auxiliary lead-out structure 231 and the main static contact 211 being led out from the same side of the housing 100, thereby extending the insulation distance between the two.

[0047] Based on the structural design of the functional module 200 including the auxiliary contact component, in one embodiment of the present disclosure, the auxiliary contact component includes two auxiliary static contact lead-out pieces, two auxiliary lead-out structures 231 and an auxiliary moving contact piece, each end of the two auxiliary static contact lead-out pieces serves as an auxiliary static contact and is used to contact or separate with the two ends of the auxiliary moving contact piece, each other end of the two auxiliary static contact lead-out pieces is respectively connected to each other end of the two auxiliary lead-out structures 231 (for example, connected by soldering), and each other end of the two auxiliary lead-out structures 231 is led out from the same side of the housing 100.

[0048] Based on the design that the auxiliary contact assembly includes two auxiliary static contact lead-out pieces and two auxiliary lead-out structures 231, in one embodiment of the present disclosure, the auxiliary contact assembly may include only one auxiliary moving contact piece, both ends of the auxiliary moving contact piece are provided with auxiliary moving contacts, one end of each of the two auxiliary static contact lead-out pieces is used as an auxiliary static contact, and the two auxiliary static contacts are used to contact or separate with the two auxiliary moving contacts, that is, the auxiliary contact assembly is a bridge contact structure. In some embodiments, the auxiliary contact assembly may also be a snap-on contact structure, that is, the auxiliary contact assembly may include at least one group of contact structures, each group of contact structures includes an auxiliary moving contact piece, an auxiliary static contact lead-out piece and two auxiliary lead-out structures 231, and the two auxiliary lead-out structures 231 are respectively connected to the auxiliary moving contact piece and the auxiliary static contact lead-out piece.

[0049] like Figure 2As shown, based on the structural design that the functional module 200 includes the auxiliary lead-out structure 231, in one embodiment of the present disclosure, the coil lead-out structure 2211 and the auxiliary lead-out structure 231 can both be led out from the same side of the housing 100. In other words, the auxiliary lead-out structure 231 and the main static contact 211 can be led out from opposite sides of the housing 100, respectively. Through the above structural design, the utility model can further extend the insulation distance between the auxiliary lead-out structure 231 and the main static contact 211, and at the same time realize the same-side lead-out of the coil lead-out structure 2211 and the auxiliary lead-out structure 231, which is convenient for connecting the low-voltage side lead-out structure of the relay with the external circuit.

[0050] like Figure 2 As shown, in one embodiment of the present disclosure, the auxiliary contact assembly may include two auxiliary lead-out structures 231. On this basis, each auxiliary lead-out structure 231 belonging to the same functional module 200 may be led out from the same side of the housing 100, and the auxiliary lead-out structures 231 of each functional module 200 may all be led out from the same side of the housing 100. Through the above structural design, the present disclosure can reduce the difficulty of connecting the auxiliary lead-out structure 231 of the relay with the external circuit.

[0051] See also Figure 4 , Figure 4 Detailed description of the invention is given in the figure which is a three-dimensional structural diagram of a relay in another exemplary embodiment which can embody the principles of the present disclosure.

[0052] like Figure 4 As shown, in one embodiment of the present disclosure, when each functional module 200 includes two auxiliary lead-out structures 231, the two auxiliary lead-out structures 231 belonging to one functional module 200 can be led out from different sides of the housing 100. For example, the arrangement direction of at least two functional modules 200 is defined as the second direction Y, and the second direction Y is perpendicular to the first direction X mentioned above, and a third direction Z perpendicular to the first direction X and the second direction Y is defined at the same time. On this basis, when the main static contact 211 is led out from one side of the housing 100 in the first direction X, the two auxiliary lead-out structures 231 belonging to one functional module 200 can be led out from both sides of the housing 100 in the third direction Z, respectively.

[0053] See also Figure 5 , Figure 5 Detailed description of the invention is given in the figure which is a three-dimensional structural diagram of a relay in another exemplary embodiment which can embody the principles of the present disclosure.

[0054] like Figure 5As shown, in one embodiment of the present disclosure, when each functional module 200 includes two auxiliary lead-out structures 231, the two auxiliary lead-out structures 231 belonging to one functional module 200 can be led out from the same side of the housing 100. For example, when the main static contact 211 is led out from one side of the housing 100 in the first direction X, the two auxiliary lead-out structures 231 belonging to one functional module 200 can be led out from both sides of the housing 100 in the third direction Z, respectively.

[0055] like Figures 1 to 3 As shown, in one embodiment of the present disclosure, taking the relay including two functional modules 200 as an example, the two functional modules 200 can be arranged along the second direction Y, and the second direction Y is perpendicular to the first direction X. For example, the first direction X can be the height direction of the relay, and the main static contact 211 can be led out from the top surface 101 of the housing 100, and the coil lead-out structure 2211 can be led out from the bottom surface 102 of the housing 100.

[0056] 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. It should be clearly understood that the principles of the present disclosure are by no means limited to any details or any components of the relays shown in the drawings or described in this specification.

[0057] In summary. The relay proposed in the present disclosure includes a housing 100 and at least two functional modules 200; the functional module 200 is partially arranged in the housing 100; the functional module 200 includes a main contact assembly and a magnetic circuit part, the main contact assembly includes a main static contact 211 and an active spring assembly, the magnetic circuit part 220 includes a coil assembly, and the coil assembly is connected to a coil lead-out structure 2211; the main static contact 211 and the coil lead-out structure 2211 are respectively led out from the housing 100 on opposite sides along the first direction X. Through the above-mentioned structural design, in the present disclosure, the main static contact 211 and the coil lead-out structure 2211 are led out from opposite sides of the housing 100, which can extend the insulation distance between the main static contact 211 and the coil lead-out structure 2211, thereby improving the insulation performance of the relay.
