[0027] In one embodiment of the present disclosure, when the coil lead-out structure is connected to one end of the coil assembly away from the main contact assembly in the first direction, the present disclosure can further optimize the arrangement of the coil lead-out structure and the auxiliary lead-out structure inside the outer shell, so that the above two low-voltage side lead-out structures are respectively arranged close to the components to be connected to them, avoiding the need for the auxiliary lead-out structure to be arranged across the coil assembly along the first direction inside the outer shell, reducing the structural complexity and simplifying the assembly difficulty.

[0029] In one embodiment of the present disclosure, when the housing includes a first housing and the first housing includes a main body with a notch and an assembly plate assembled in the notch, the present disclosure can utilize an assembly plate that is relatively independent of the main body to assemble with the auxiliary lead-out structure and the coil lead-out structure, and then assemble the assembled structure with the main body as a whole to form the first housing, which is convenient for assembling and leading out the auxiliary lead-out structure and the coil lead-out structure with the housing, which is conducive to reducing the difficulty of assembly and improving the efficiency of assembly. In addition, since the extension direction (e.g., the second direction) of the auxiliary lead-out structure and the coil lead-out structure is different from the installation direction (e.g., the first direction) of the first housing, the present invention can further utilize the design of the assembly plate to avoid the interference problem that may arise when the above-mentioned lead-out direction is different from the installation direction, and will not change the overall structure of the first housing.

[0058] 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.

[0059] 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.

[0060] See also Figure 1 , which is a representative schematic diagram of the three-dimensional structure of the relay proposed in the present disclosure. In this exemplary embodiment, the relay proposed in the present disclosure is described by taking a relay including two static contacts 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.

[0061] like Figure 1 As shown, in one embodiment of the present disclosure, the relay provided by the present disclosure includes a housing 100, a main contact assembly, an auxiliary contact assembly and a magnetic circuit part. Figures 2 to 8 , Figure 2 A representative example is shown in Figure 1 Schematic diagram of the plane; Figure 3 and Figure 4 The representative figures are shown in Figure 1 The three-dimensional structure diagram of the partial structure shown in two different viewing angles, wherein the partial structure of the relay after the housing 100 is hidden is specifically shown; Figure 5 A representative example is shown in Figure 3 A three-dimensional schematic diagram of a partial structure is shown, in which the coil assembly, the yoke iron plate 322 and the auxiliary lead-out structure A are specifically shown; Figure 6 A representative example is shown in Figure 5A three-dimensional exploded schematic diagram, in which the yoke iron plate 322 and the coil assembly are separated along the first direction X; Figure 7 A three-dimensional structural schematic diagram of the coil frame 312 is representatively shown in FIG. Figure 8 The three-dimensional structural diagram of the auxiliary lead-out structure A is representatively shown in FIG. 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.

[0062] like Figures 1 to 4 As shown, in one embodiment of the present disclosure, the main contact assembly is arranged in the housing 100, and the main contact assembly includes a main static contact 211, and the main static contact 211 is led out from one side of the housing 100 along the first direction X. Among them, the main static contact 211 can be used as a high-voltage side lead-out structure of the relay. The auxiliary contact assembly and the magnetic circuit part are partially arranged in the housing 100, and the auxiliary contact assembly includes an auxiliary lead-out structure A, and the magnetic circuit part includes a coil assembly, and the coil assembly is connected to a coil lead-out structure B, and the auxiliary lead-out structure A and the coil lead-out structure B are both led out from the same side of the housing 100 along the second direction Y, and the first direction X is perpendicular to the second direction Y. Among them, the auxiliary lead-out structure A and the coil lead-out structure B can be used as a low-voltage side lead-out structure of the relay. Through the above design, the present invention leads out the high-voltage side lead-out structure (i.e., the main static contact 211) and the low-voltage side lead-out structure (i.e., the auxiliary lead-out structure A and the coil lead-out structure B) of the relay from different sides of the housing 100 in two perpendicular directions, thereby enabling the relay to be installed in a horizontal manner, that is, the lead-out direction of the low-voltage side lead-out structure (i.e., the second direction Y) is perpendicular to the installation plane of the external device, thereby reducing the installation space of the relay in the height direction, which is beneficial to the installation of the relay in a small space.

[0063] It should be noted that in this specification, the lead-out direction of each lead-out structure specifically refers to the extension direction of the lead-out part of the lead-out structure, that is, the extension direction of the part of the lead-out structure leading out of the shell, and does not limit the shape and arrangement direction of the lead-out structure inside the shell.

[0064] Specifically, when the relay proposed in the present disclosure is installed in a horizontal manner, since the auxiliary lead-out structure A and the coil lead-out structure B are both led out from the same side of the housing 100 along the second direction Y, relative to the installation position of the relay, such as the installation plane of the external device, the present disclosure can realize that the auxiliary lead-out structure A and the coil lead-out structure B are both assembled to the external device in a plug-in manner, and the plug-in direction is the second direction Y, that is, the direction perpendicular to the installation plane of the external device, thereby further reducing the difficulty of assembly and improving assembly efficiency. On this basis, the lead-out parts of the auxiliary lead-out structure A and the coil lead-out structure B can both be in a plug-in-shaped structure, thereby increasing the plug-in force and improving the connection reliability, thereby further being suitable for the plug-in assembly method.

[0065] In one embodiment of the present disclosure, the main contact assembly further includes an active contact sheet, and the main contact assembly includes two main static contacts 211. For example, the main contact assembly may include only one active contact sheet, both ends of which are provided with active contacts, and the two main static contacts 211 are respectively used to contact or separate with the two active contacts, that is, the main contact assembly is a bridge contact structure. For another example, the main contact assembly may also include two active contact sheets, both ends of which are provided with active contacts, and the two main static contacts 211 are respectively arranged corresponding to the two ends of the two active contact sheets.

[0066] like Figure 8 As shown, in one embodiment of the present disclosure, the auxiliary contact assembly includes two auxiliary static contact lead-out pieces, two auxiliary lead-out structures A 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 end of the two auxiliary lead-out structures A, and each other end of the two auxiliary lead-out structures A is led out from the housing 100.

[0067] like Figures 1 to 6 and Figure 8 As shown, based on the design that the auxiliary contact assembly includes two auxiliary lead-out structures A, in one embodiment of the present disclosure, the other ends of the two auxiliary lead-out structures A can be arranged at intervals along a third direction Z, and the third direction Z is perpendicular to the first direction X and perpendicular to the second direction Y.

[0068] Based on the design that the auxiliary contact assembly includes two auxiliary static contact lead-out pieces and two auxiliary lead-out structures A, 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 A, and the two auxiliary lead-out structures A are respectively connected to the auxiliary moving contact piece and the auxiliary static contact lead-out piece.

[0069] It should be noted that in this embodiment, the auxiliary lead-out structure A is connected to the auxiliary static contact lead-out piece of the auxiliary contact assembly as an example for explanation, that is, the auxiliary lead-out structure A is a lead-out structure serving as an auxiliary static contact of the auxiliary contact assembly. It should be understood that in another embodiment of the present disclosure, the auxiliary lead-out structure A may also be a lead-out structure connected to the auxiliary moving contact piece, that is, one end of the auxiliary lead-out structure A is connected to the auxiliary moving contact piece, and the other end of the auxiliary lead-out structure A extends out of the housing 100 and serves as a lead-out pin of the auxiliary moving contact piece, and is not limited to the above embodiment.

[0070] like Figure 2 As shown, based on the design that the auxiliary contact assembly includes two auxiliary lead-out structures A, in one embodiment of the present disclosure, the two auxiliary lead-out structures A may be located at the same position in the first direction X.

[0071] like Figures 1 to 4 As shown, in one embodiment of the present disclosure, in the first direction X, the magnetic circuit portion is located on the side of the main contact assembly opposite to the lead-out direction of the main static contact 211. On this basis, the coil lead-out structure B can be connected to the side of the coil assembly that is away from the main contact assembly in the first direction X. That is, the lead-out portion of the coil lead-out structure B can be located on the side of the lead-out portion of the auxiliary lead-out structure A that is away from the main static contact 211 in the first direction X. Through the above design, the present disclosure can further optimize the arrangement of the coil lead-out structure B and the auxiliary lead-out structure A inside the housing 100, so that the above two low-voltage side lead-out structures are respectively arranged near the components to be connected to each other, avoiding the auxiliary lead-out structure A from being arranged across the coil assembly along the first direction X in the housing 100, reducing the structural complexity and simplifying the assembly difficulty.

[0072] like Figure 2 As shown, in one embodiment of the present disclosure, along the first direction X, the auxiliary lead-out structure A and the coil lead-out structure B can be arranged at intervals, thereby further reducing the difficulty of assembly.

[0073] like Figure 2 As shown, in one embodiment of the present disclosure, along the third direction Z, the auxiliary lead-out structure A and the coil lead-out structure B can be arranged in a staggered manner. Through the above design, the present disclosure can avoid interference between the coil lead-out structure B when the auxiliary lead-out structure A needs to be connected to other connectors, and ensure the smooth connection of the relay low-voltage side lead-out structure with other connectors. In some embodiments, the auxiliary lead-out structure A and the coil lead-out structure B can also be arranged correspondingly in the third direction Z, which is not limited to this embodiment.

[0074] like Figure 3 and Figure 4As shown, in one embodiment of the present disclosure, the coil assembly includes a coil 311, the winding axis of the coil 311 is parallel to the first direction X, and both ends of the coil 311 are connected to a coil lead-out structure B. On this basis, the two coil lead-out structures B can be located at the same position in the first direction X, for example, both are located at one end of the coil assembly away from the main contact assembly, and the two coil lead-out structures B can be arranged at intervals in the third direction Z. Through the above design, the present disclosure can facilitate the connection of the two coil lead-out structures B with the external circuit or other connectors, and avoid interference caused by the two coil lead-out structures B being too close.

[0075] like Figures 3 to 8 As shown, in one embodiment of the present disclosure, the magnetic circuit portion includes a yoke assembly, the yoke assembly includes a U-shaped yoke 321 and a yoke plate 322, the U-shaped yoke 321 includes a side portion, and the yoke plate 322 is connected to one end of the side portion facing the main contact assembly. In addition, the coil assembly includes a coil frame 312 and a coil 311, the coil frame 312 is arranged in the yoke assembly, and the coil 311 is wound around the coil frame 312. On this basis, at least a part of the auxiliary lead-out structure A located in the housing 100 can be arranged between the coil frame 312 and the yoke plate 322. Further, the auxiliary static contact lead-out piece can be located between the yoke plate 322 and the coil frame 312, and the auxiliary lead-out structure A located between the yoke plate 322 and the coil frame 312 can be soldered to the auxiliary static contact lead-out piece. Through the above design, the present disclosure can improve the connection reliability and connection efficiency of the auxiliary lead-out structure A, and at the same time can use the coil frame 312 and the yoke iron plate 322 to limit the auxiliary lead-out structure A in various directions in space.

[0076] In addition, the magnetic circuit part also includes an iron core assembly, which is accommodated in the through hole of the coil frame 312, 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 311, a certain current flows through the coil 311, 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 311 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 211.

[0077] like Figures 5 to 8As shown, based on the design that the auxiliary lead-out structure A is partially arranged between the coil frame 312 and the yoke iron plate 322, in one embodiment of the present disclosure, a part of the auxiliary lead-out structure A is provided with an insulating member 411, and the two ends of the auxiliary lead-out structure A respectively extend out of the insulating member 411. For example, the auxiliary lead-out structure A has a lead-out end a1 and a connecting end a2 respectively extending out of the insulating member 411, and the lead-out end a1 is led out from the housing 100 along the second direction Y, and the connecting end a2 is connected to one end of the auxiliary static contact lead-out member (for example, it can be connected by soldering). In other words, the auxiliary lead-out structure A is wrapped by the insulating member 411 except for the ends used to connect the auxiliary static contact lead-out member and the lead-out. On this basis, the insulating member 411 is at least partially arranged between the coil frame 312 and the yoke iron plate 322, and the auxiliary lead-out structure A and the insulating member 411 can be integrally injection molded. Through the above design, the present disclosure can utilize the insulating member 411 to ensure the insulation performance between the auxiliary lead-out structure A and the coil frame 312 and the yoke iron plate 322 , thereby further improving the connection reliability and connection efficiency of the auxiliary lead-out structure A.

[0078] In one embodiment of the present disclosure, the lead-out portion of the main static contact 211 may extend along the first direction X, and the so-called lead-out portion refers to the portion of the main static contact 211 that is led out of the housing 100 .

[0079] In one embodiment of the present disclosure, the lead-out portion of the auxiliary lead-out structure A may extend along the second direction Y, and the so-called lead-out portion refers to the portion of the auxiliary lead-out structure A outside the lead-out housing 100. Through the above design, the present disclosure can make the lead-out portion of the auxiliary lead-out structure A more convenient to connect with an external device, for example, the lead-out portion can be connected to a mounting surface of an external device perpendicular to the second direction Y in a plug-in manner.

[0080] In one embodiment of the present disclosure, the lead-out portion of the coil lead-out structure B may extend along the second direction Y, and the so-called lead-out portion refers to the portion of the coil lead-out structure B outside the lead-out housing 100. Through the above design, the present disclosure can make the lead-out portion of the coil lead-out structure B more convenient to connect with an external device, for example, the lead-out portion can be connected to a mounting surface of an external device perpendicular to the second direction Y in a plug-in manner.

[0081] like Figure 1 and Figure 2As shown, in one embodiment of the present disclosure, the housing 100 includes two first walls 101 and two second walls 102, the two first walls 101 are arranged at intervals along the first direction X and are both perpendicular to the first direction X, and the two second walls 102 are arranged at intervals along the second direction Y and are both perpendicular to the second direction Y. On this basis, each main static contact 211 can be led out from one of the first walls 101, and the auxiliary lead-out structure A and the coil lead-out structure B are both led out from one of the second walls 102. Through the above design, the present disclosure can realize that the lead-out directions of the high-voltage side lead-out structure and the low-voltage side lead-out structure are both relative to the wall surface of the housing 100 perpendicular to each of which they are led out, especially the lead-out direction of the low-voltage side lead-out structure (i.e., the second direction Y) is perpendicular to the wall surface (i.e., the second wall 102) from which it is led out, so that when the relay is installed in a horizontal manner, the lead-out wall surface of the low-voltage side lead-out structure is ensured to be parallel to the installation plane of the external device, thereby realizing the fit between the wall surface of the housing 100 and the installation plane of the external device, further improving the installation effect of the relay. In other embodiments of the present disclosure, for the high-voltage side lead-out structure and / or the low-voltage side lead-out structure of the relay, the wall surface of the housing 100 from which it is led out may also be inclined relative to its lead-out direction (i.e., having an angle other than 0, 90° and 180°). For example, the above-mentioned wall surface of the housing 100 may also be a non-planar surface, such as a curved surface, etc., which is not limited to the present embodiment.

[0082] like Figure 1 and Figure 2 As shown, based on the design that the housing 100 includes two first walls 101 and two second walls 102, in one embodiment of the present disclosure, the housing 100 may further include two third walls 103, which are arranged at intervals along the third direction Z and are both perpendicular to the third direction Z; on this basis, the surface area of ​​the second wall 102 is greater than the surface area of ​​the third wall 103. Through the above design, the present disclosure leads both the auxiliary lead-out structure A and the coil lead-out structure B from the second wall 102 of the housing 100. Since the second wall 102 has a larger surface area than the third wall 103, when the relay is installed in a horizontal position on an external device, the space occupied in the height direction (the direction perpendicular to the external device, i.e., the second direction Y) can be further reduced. In some embodiments, when the housing 100 has a second wall 102 and a third wall 103, the surface area of ​​the second wall 102 may also be smaller than the surface area of ​​the third wall 103, and the auxiliary lead-out structure A and the coil lead-out structure B may also be led out from the second wall 102 with a relatively larger surface area, which is not limited to this embodiment.

[0083] See also Figures 9 to 12 As shown, Fig. 9 : A three-dimensional structural diagram of a relay in another exemplary embodiment that can embody the principles of the present disclosure is representatively shown; Fig.10A representative example is shown in Fig. 9 The three-dimensional exploded schematic diagram of the relay shown, wherein the first housing and the second housing are separated along the first direction; Fig.11 A three-dimensional structural schematic diagram of the assembly plate 112 is representatively shown in FIG. Fig.12 A three-dimensional structural diagram of the main body 111 is representatively shown in FIG. Fig.13 , a partial cross-sectional schematic diagram of the housing 100 is representatively shown, wherein the cross-sectional structure of the matching position between the notch 1111 of the body 111 of the first housing 110 and the assembly plate 112 is specifically shown.

[0084] like Fig. 9 and Fig.10 As shown, in one embodiment of the present disclosure, the housing 100 may include a first shell 110 and a second shell 120, wherein the first shell 110 is a hood-like structure and has an end wall 1112 and a side wall 1113. The end wall 1112 is an end wall surface of the first shell 110 in the first direction X, that is, the end wall 1112 is perpendicular to the first direction X. The other end of the first shell 110 in the first direction X is an opening 1101, and the main static contact 211 is led out from the end wall 1112. The side wall 1113 may be formed by enclosing a plurality of (at least three) planar or curved wall surfaces, or may be an integral enclosed curved surface (e.g., a cylindrical surface, an elliptical cylindrical surface, etc.). The second shell 120 is disposed at the opening 1101 of the first shell 110, for example, the second shell 120 may serve as an end plate that closes the other end of the first shell 110 in the first direction X. On this basis, the first shell 110 includes a body 111 and an assembly plate 112. The body 111 is provided with a notch 1111 on the side wall 1113. The notch 1111 is connected to the opening 1101 of the first shell 110. The assembly plate 112 is arranged on the notch 1111 of the body 111 and serves as a part of the side wall 1113. On this basis, the auxiliary lead-out structure A and the coil lead-out structure B can both be assembled on the assembly plate 112 and led out by the assembly plate 112 along the second direction Y. Through the above design, the present disclosure can utilize the assembly plate 112 which is relatively independent from the body 111 to assemble the auxiliary lead-out structure A and the coil lead-out structure B, and then assemble the assembled structure as a whole with the body 111 to form the first shell 110, which is convenient for the assembly and lead-out of the auxiliary lead-out structure A and the coil lead-out structure B with the housing 100, and is conducive to reducing the difficulty of assembly and improving the assembly efficiency. Furthermore, since the extension direction (for example, the second direction Y) of the auxiliary lead-out structure A and the coil lead-out structure B is different from the installation direction (for example, the first direction X) of the first shell 110, the utility model can further utilize the design of the assembly plate 112 to avoid the interference problem that may arise when the above-mentioned lead-out direction is different from the installation direction, and will not change the overall structure of the first shell 110.

[0085] Based on the design that the first housing 110 includes a body 111 and an assembly plate 112, in one embodiment of the present disclosure, a guide limiting structure may be provided between the edge of the assembly plate 112 in the third direction Z (i.e., the edge of the assembly plate 112 extending along the first direction X) and the edge of the notch 1111 (i.e., the edge of the notch 1111 extending along the first direction X). The guide limiting structure is suitable for realizing the assembly of the assembly plate 112 and the notch 1111 along the first direction X, and is suitable for limiting the relative position of the assembly plate 112 and the body 1111 in the second direction Y. Through the above design, the present disclosure can realize the assembly of the assembly plate 112 and the notch 1111, further improve the convenience of assembly, and reduce the difficulty of assembly. At the same time, the present disclosure can limit the assembly plate 112 and the body 111 of the first housing 110 in the second direction Y, so as to prevent the assembly plate 112 from slipping out of the body 111, thereby ensuring the structural stability of the relay.

[0086] like Figures 11 to 13 As shown, based on the design of the guide limit structure, in one embodiment of the present disclosure, the guide limit structure may specifically include a first limit strip 1114 and a second limit strip 1121. The first limit strip 1114 is provided on both side edges (or only on one side edge) of the notch 1111 in the third direction Z, and the second limit strip 1121 is provided on both side edges (or only on one side edge) of the assembly plate 112 in the third direction Z. The first limit strip 1114 and the second limit strip 1121 both extend along the first direction X, thereby enabling the assembly plate 112 and the notch 1111 to be assembled along the first direction X. On this basis, in the second direction Y, the first limit strip 1114 is located on the relatively outer side of the second limit strip 1121 (that is, the first limit strip 1114 is closer to the outer surface of the shell 100 than the second limit strip 1121), thereby enabling the assembly plate 112 and the main body 1111 to be limited in the second direction Y, and utilizing the blocking effect of the first limit strip 1114 on the second limit strip 1121 to prevent the assembly plate 112 from slipping out of the main body 1111 of the first shell 100.

[0087] like Fig.10 As shown, based on the design that the housing 100 includes a first housing 110 and a second housing 120, in one embodiment of the present disclosure, the first housing 110 and the second housing 120 can be assembled via a snap-fit ​​structure. In some embodiments, the first housing 110 and the second housing 120 can also be assembled via other forms, such as by connecting a connector, etc., which is not limited to this embodiment.

[0088] It should be noted that, based on the design that the housing 100 includes the first housing 110, in one embodiment of the present disclosure, the first housing 110 may be an integrated cover-like structure, that is, the end wall 1112 and the side wall 1113 of the first housing 110 are both integrated structures. In some embodiments, the first housing 110 may also be formed by connecting and assembling a plurality of relatively independent parts (e.g., a plurality of panels). Figure 1 and Figure 2 In the illustrated embodiment, the housing 100 may also be formed by connecting and assembling a plurality of relatively independent parts (eg, a plurality of panels).

[0089] Based on the design that the housing 100 includes the second housing 120, in one embodiment of the present disclosure, the magnetic circuit part can be arranged on the bottom plate 122. In other words, when the relay proposed in the present disclosure is assembled, the functional components (such as the main contact assembly, the auxiliary contact assembly and the magnetic circuit part) can be assembled first, and then the assembled structure can be assembled with the second housing 120, and then assembled with the assembly plate 112, that is, the low-voltage side lead-out structures are assembled with the assembly plate 112 along the second direction Y, and finally the body 111 of the first housing 110 is assembled along the first direction X, and the assembly plate 112 is assembled to the notch 1111 of the body 111. Alternatively, the functional components can be assembled first, and then the assembled structure can be assembled with the assembly plate 112, and then the body 111 of the first housing 110 can be assembled, and finally the second housing 120 can be assembled.

[0090] like Fig. 9 and Fig.10 As shown, based on the design that the housing 100 includes a first shell 110 and the first shell 110 includes an assembly plate 112, in one embodiment of the present disclosure, the assembly plate 112 may be provided with a first through hole, and the first through hole can allow the coil lead-out structure A to be led out.

[0091] like Fig. 9 and Fig.10 As shown, based on the design that the housing 100 includes a first shell 110 and the first shell 110 includes an assembly plate 112, in one embodiment of the present disclosure, a through groove may be provided on one side edge of the assembly plate 112 close to the main contact assembly, and the through groove and the inner edge of the notch 1111 together form a second through hole, and the second through hole can be used for the auxiliary lead-out structure B to be led out.

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

[0093] In summary, the relay proposed in the present disclosure includes a main contact assembly, an auxiliary contact assembly and a magnetic circuit part. The main static contact 211 of the main contact assembly is led out from one side of the housing 100 along the first direction X, and the auxiliary lead-out structure A of the auxiliary contact assembly and the coil lead-out structure B of the magnetic circuit part are both led out from the same side of the housing 100 along the second direction Y, and the second direction Y is perpendicular to the first direction X. Through the above design, the present disclosure leads the high-voltage side lead-out structure (i.e., the main static contact 211) and the low-voltage side lead-out structure (i.e., the auxiliary lead-out structure A and the coil lead-out structure B) of the relay from different sides of the housing 100 along two perpendicular directions, respectively, thereby enabling the relay to be installed in a horizontal manner, i.e., the lead-out direction of the low-voltage side lead-out structure (i.e., the second direction Y) is perpendicular to the installation plane of the external device, thereby reducing the installation space of the relay in the height direction, which is conducive to the installation of the relay in a narrow space.

[0094] Based on the above-mentioned Fig. 9 and Fig.10 Description of the exemplary embodiment shown, an exemplary embodiment of the assembly method of the relay proposed by the present disclosure will be described below.
