Description

Technical Field

[0001] The present disclosure relates to a relay. 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] High-voltage DC relay is a kind of relay. In the existing design of high-voltage DC relay, in order to extend the insulation distance between the high-voltage and low-voltage lead structures of the relay, the low-voltage side lead structure (such as auxiliary lead structure or coil lead structure) and the high-voltage side lead structure (such as main static contact) of the relay are led out from different sides of the housing. As a result, the high-voltage and low-voltage lead structures are assembled along different directions (such as perpendicular directions) relative to the housing. However, the housing of the existing relay adopts an integral structure, which makes assembly difficult and affects assembly efficiency. Utility Model Content

[0050] 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.

[0051] 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.

[0052] 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 main static contacts 310 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.

[0053] like Figure 1 As shown, in one embodiment of the present disclosure, the relay provided by the present disclosure includes a housing, a main contact assembly and a magnetic circuit part. Figures 2 to 5 , Figure 2 Representatively shown in Figure 1 A three-dimensional exploded schematic diagram, in which the first shell 110 and the second shell 120 are separated along the first direction X; Figure 3 A three-dimensional structural schematic diagram of the assembly plate 112 is representatively shown in FIG. Figure 4 A three-dimensional structural schematic diagram of the first housing 110 is representatively shown in FIG. Figure 51 is a partial cross-sectional schematic diagram of the housing, which specifically shows the cross-sectional structure of the mating point between the notch 1111 of the main body of the first housing 110 and the assembly plate 112. The structure, connection method 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.

[0054] like Figures 1 to 4As shown, in one embodiment of the present disclosure, the housing includes a first shell 110 and a second shell 120. 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. The other end of the first shell 110 in the first direction X is an opening 1101. The side wall 1113 can be formed by enclosing a plurality of (at least three) planar or curved wall surfaces, or can be an integral enclosed curved surface (such as a cylindrical surface, an elliptical cylindrical surface, etc.). The second shell 120 is arranged at the opening 1101 of the first shell 110, that is, the second shell 120 can 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 housing 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 housing 110. The assembly plate 112 is arranged in the notch 1111 of the body 111 and serves as a part of the side wall 1113. The main contact assembly is partially placed in the housing. The main contact assembly includes a main static contact 310 and an active contact piece. The two ends of the active contact piece are used to contact or separate with the main static contact 310. The main static contact 310 is led out from the end wall 1112 along the first direction X. The main static contact 310 is the high-voltage side lead-out structure of the relay. The magnetic circuit part is partially arranged in the shell, and the magnetic circuit part includes a coil assembly, and the coil assembly is connected to a coil lead-out structure 420, and the coil lead-out structure 420 is assembled on the assembly plate 112, and the coil lead-out structure 420 is led out from the assembly plate 112 along a second direction Y perpendicular to the first direction X, and the coil lead-out structure 420 is a part of the low-voltage side lead-out structure of the relay. Through the above design, the relay proposed in the present disclosure leads the main static contact 310 and the coil lead-out structure 420 from two different wall surfaces of the shell (such as the above-mentioned end wall 1112 and side wall 1113), that is, the high and low voltage lead-out structures are led out on different sides of the shell. On this basis, the present disclosure can facilitate the assembly of the high and low voltage lead-out structures along different directions relative to the shell, improve the rationality of the structure, reduce the difficulty of assembly, and help improve the assembly efficiency. For example, the present disclosure can first assemble at least some of the functional components (such as the main contact assembly and the magnetic circuit part) inside the shell with the assembly plate 112, 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 extraction of the coil lead-out structure 420 and the shell, which is conducive to reducing the difficulty of assembly and improving the assembly efficiency. In addition, since the lead-out direction (i.e., the second direction Y) of the coil lead-out structure 420 is different from the installation direction (e.g., the first direction X) of the first shell 110, the present utility model can further utilize the design of the assembly plate 112 to avoid the interference problem that may arise when the lead-out direction is different from the installation direction, and will not change the overall structure of the first shell 110.

[0055] 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.

[0056] 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 111 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.

[0057] like Figures 3 to 5 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 than the second limit strip 1121), thereby enabling the assembly plate 112 and the main body 111 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 111 of the first shell 100.

[0058] 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 be used for the coil lead-out structure 420 to be led out.

[0059] like Figure 1 and Figure 2As shown, in one embodiment of the present disclosure, the first shell 110 and the second shell 120 of the housing can be connected via a snap-fit ​​structure, and the snap-fit ​​structure can include a snap block and a snap slot, one of which is provided on the first shell 110, and the other is provided on the second shell 120. Further, the snap-fit ​​structure can be preferably provided between the body 111 and the second shell 120. Through the above design, the present disclosure can further facilitate the assembly of the first shell 110 and the second shell 120.

[0060] In one embodiment of the present disclosure, the first housing 110 may be an integrated cover-shaped structure, that is, the end wall 1112 and the side wall 1113 of the first housing 110 are an integrated structure. 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 may also be formed by connecting and assembling a plurality of relatively independent parts (eg, a plurality of panels).

[0061] In one embodiment of the present disclosure, the lead-out portion of the main static contact 310 may extend along the first direction X, and the so-called lead-out portion refers to the portion of the main static contact 310 that is outside the lead-out housing.

[0062] In one embodiment of the present disclosure, the lead-out portion of the coil lead-out structure 420 may extend along the second direction Y, and the so-called lead-out portion refers to the portion outside the lead-out housing of the coil lead-out structure 420. Through the above design, the present disclosure can make the lead-out portion of the coil lead-out structure 420 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.

[0063] like Figure 1 As shown, in one embodiment of the present disclosure, the relay proposed in the present disclosure also includes an auxiliary contact assembly, which is partially arranged in the shell, and the auxiliary contact assembly includes two auxiliary static contact lead-out pieces, two auxiliary lead-out structures 320 and an auxiliary moving contact piece, and each end of the two auxiliary static contact lead-out pieces is used as an auxiliary static contact to contact or separate with the two ends of the auxiliary moving contact piece, and each other end of the two auxiliary static contact lead-out pieces is respectively connected to each one end of the two auxiliary lead-out structures 320, and each other end of the two auxiliary lead-out structures 320 is led out from the shell.

[0064] like Figure 1As shown, based on the design that the relay includes an auxiliary contact assembly and the auxiliary contact assembly includes an auxiliary lead-out structure 320, in one embodiment of the present disclosure, the auxiliary lead-out structure 320 and the main static contact 310 can be led out from the housing along opposite sides of the first direction X, that is, the auxiliary lead-out structure 320 is led out from the second housing 120 along the first direction X. Through the above design, the present disclosure can realize the lead-out of high and low voltage lead-out structures on different sides, and further on opposite sides, thereby further improving the insulation distance between the two. On this basis, when the auxiliary lead-out structure 320 is led out from the second housing 120, the auxiliary contact assembly can also be a functional component that is first assembled with the second housing 120, thereby further improving the convenience of assembly. In some embodiments, the auxiliary lead-out structure 320 can also be led out from other sides of the housing, which is not limited to this embodiment.

[0065] based on Figures 1 to 5 The designs of the various embodiments shown, in an embodiment not shown in the present disclosure, the magnetic circuit part also includes a yoke assembly, the yoke assembly includes a U-shaped yoke 510 and a yoke plate 520, the U-shaped yoke 510 includes a side, and the yoke plate 520 is connected to one end of the side facing the contact assembly. In addition, the coil assembly includes a coil frame 430 and a coil 410, the coil frame 430 is arranged in the yoke assembly, and the coil 410 is wound around the coil frame 430. On this basis, at least a part of the part of the auxiliary lead-out structure 320 located in the housing can be arranged between the coil frame 430 and the yoke plate 520. Further, the part of the auxiliary lead-out structure 320 that cooperates with the auxiliary moving contact piece (that is, the two are correspondingly contacted or separated) can be located between the yoke plate 520 and the coil frame 430, and this part of the auxiliary lead-out structure 320 can be connected to the auxiliary static contact via soldering. Through the above design, the present disclosure can improve the connection reliability and connection efficiency of the auxiliary lead-out structure 320, and at the same time can use the coil frame 430 and the yoke iron plate 520 to limit the auxiliary lead-out structure 320 in various directions in space.

[0066] Based on the design that the auxiliary lead-out structure 320 is partially disposed between the coil frame 430 and the yoke iron plate 520, in an embodiment not shown in the figure in the present disclosure, a part of the auxiliary lead-out structure 320 is provided with an insulating member 321, and the two ends of the auxiliary lead-out structure 320 extend out of the insulating member 321 respectively. For example, the auxiliary lead-out structure 320 has a lead-out end 3201 and a connecting end 3202 that extend out of the insulating member 321 respectively, and the lead-out end 3201 is led out from the housing along the second direction Y, and the connecting end 3202 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 320 is wrapped by the insulating member 321 except for the ends used to connect the auxiliary static contact lead-out member and the lead-out. On this basis, the insulating member 321 is at least partially disposed between the coil frame 430 and the yoke iron plate 520, and the auxiliary lead-out structure 320 and the insulating member 321 can be integrally injection molded. Through the above design, the present disclosure can utilize the insulating member 321 to ensure the insulation performance between the auxiliary lead-out structure 320 and the coil frame 430 and the yoke iron plate 520 , and further improve the connection reliability and connection efficiency of the auxiliary lead-out structure 320 .

[0067] In addition, the magnetic circuit part also includes an iron core assembly, which is accommodated in the through hole of the coil frame 430, 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 410, a certain current flows through the coil 410, 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 310. When the coil 410 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 310.

The housing includes a first housing 110 and a second housing 120. The first housing 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 housing 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 housing 110 in the first direction X is an opening 1101. The side wall 1113 can be formed by enclosing a plurality of (at least three) planar or curved wall surfaces, or can be an integral enclosed curved surface (such as a cylindrical surface, an elliptical cylindrical surface, etc.). The second housing 120 is disposed at the opening 1101 of the first housing 110 and closes the opening 1101, that is, the second housing 120 can serve as an end plate that closes the other end of the first housing 110 in the first direction X. On this basis, the first housing 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 housing 110. The assembly plate 112 is arranged in the notch 1111 of the body 111 and serves as a part of the side wall 1113. The main contact assembly is partially arranged in the housing. The main contact assembly includes a main static contact 310 and an active contact. Both ends of the active contact are used to contact or separate with the main static contact 310. The main static contact 310 is led out from the end wall 1112 along the first direction X. The main static contact 310 is the high-voltage side lead-out structure of the relay. The auxiliary contact assembly is partially arranged in the housing, and the auxiliary contact assembly includes an auxiliary lead-out structure 320, which is assembled on the assembly plate 112, and the auxiliary lead-out structure 320 is led out from the assembly plate 112 along the second direction Y perpendicular to the first direction X, and the assembly plate 112 is perpendicular to the second direction Y, and the auxiliary lead-out structure 320 is a part of the low-voltage side lead-out structure of the relay. Through the above design, the relay proposed in the present disclosure has the main static contact 310 and the auxiliary lead-out structure 320 respectively from two different wall surfaces of the housing (such as the above-mentioned end wall 1112 and side wall 1113), that is, the high and low voltage lead-out structures are led out on different sides of the housing. On this basis, the present disclosure can facilitate the assembly of the high and low voltage lead-out structures along different directions relative to the housing, improve the rationality of the structure, reduce the difficulty of assembly, and help improve the assembly efficiency. For example, the present invention can first assemble at least some functional components inside the shell (such as the main contact assembly and the auxiliary contact assembly) with the assembly plate 112, and then assemble the assembled structure as a whole with the main body 111 to form the first shell 110, which is convenient for the assembly and lead-out of the auxiliary lead-out structure 320 with the shell, which helps to reduce the difficulty of assembly and improve assembly efficiency.Furthermore, since the lead-out direction (i.e., the second direction Y) of the auxiliary lead-out structure 320 is different from the installation direction (e.g., 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 lead-out direction is different from the installation direction, and will not change the overall structure of the first shell 110.

[0070] 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 111 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.

[0071] Based on the design of the guide and limit structure, in one embodiment of the present disclosure, the guide and 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 than the second limit strip 1121), thereby enabling the assembly plate 112 and the main body 111 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 111 of the first shell 100.

[0072] 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 320 to lead out.

[0073] like Figure 6 and Figure 7As shown, in one embodiment of the present disclosure, the first shell 110 and the second shell 120 of the housing can be connected via a snap-fit ​​structure, and the snap-fit ​​structure can include a snap block and a snap slot, one of which is provided on the first shell 110, and the other is provided on the second shell 120. Further, the snap-fit ​​structure can be preferably provided between the body 111 and the second shell 120. Through the above design, the present disclosure can further facilitate the assembly of the first shell 110 and the second shell 120.

[0074] In one embodiment of the present disclosure, the first housing 110 may be an integrated cover-shaped structure, that is, the end wall 1112 and the side wall 1113 of the first housing 110 are an integrated structure. 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 may also be formed by connecting and assembling a plurality of relatively independent parts (eg, a plurality of panels).

[0075] In one embodiment of the present disclosure, the lead-out portion of the main static contact 310 may extend along the first direction X, and the so-called lead-out portion refers to the portion of the main static contact 310 that is outside the lead-out housing.

[0076] In one embodiment of the present disclosure, the lead-out portion of the auxiliary lead-out structure 320 may extend along the second direction Y, and the so-called lead-out portion refers to the portion outside the lead-out housing of the auxiliary lead-out structure 320. Through the above design, the present disclosure can make the lead-out portion of the auxiliary lead-out structure 320 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.

[0077] In an embodiment not shown in the figure in the present disclosure, the auxiliary contact assembly includes two auxiliary static contact lead-out pieces, two auxiliary lead-out structures 320 and an auxiliary moving contact piece, each one 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 one end of the two auxiliary lead-out structures 320, and each other end of the two auxiliary lead-out structures 320 is led out from the housing.

[0078] like Figures 10 to 13As shown, in one embodiment of the present disclosure, the relay proposed in the present disclosure also includes a magnetic circuit part, the magnetic circuit part also includes a yoke assembly, the yoke assembly includes a U-shaped yoke 510 and a yoke plate 520, the U-shaped yoke 510 includes a side, and the yoke plate 520 is connected to one end of the side facing the contact assembly. In addition, the coil assembly includes a coil frame 430 and a coil 410, the coil frame 430 is arranged in the yoke assembly, and the coil 410 is wound around the coil frame 430. On this basis, at least a part of the part of the auxiliary lead-out structure 320 located in the housing is arranged between the coil frame 430 and the yoke plate 520. Through the above design, the present disclosure can improve the connection reliability and connection efficiency of the auxiliary lead-out structure 320, and at the same time can use the coil frame 430 and the yoke plate 520 to limit the auxiliary lead-out structure 320 in various directions in space.

[0079] Based on the design that the auxiliary lead-out structure 320 is partially disposed between the coil frame 430 and the yoke iron plate 520, in an embodiment not shown in the figure in the present disclosure, a part of the auxiliary lead-out structure 320 is provided with an insulating member 321, and the two ends of the auxiliary lead-out structure 320 extend out of the insulating member 321 respectively. For example, the auxiliary lead-out structure 320 has a lead-out end 3201 and a connecting end 3202 that extend out of the insulating member 321 respectively, and the lead-out end 3201 is led out from the housing along the second direction Y, and the connecting end 3202 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 320 is wrapped by the insulating member 321 except for the ends used to connect the auxiliary static contact lead-out member and the lead-out. On this basis, the insulating member 321 is at least partially disposed between the coil frame 430 and the yoke iron plate 520, and the auxiliary lead-out structure 320 and the insulating member 321 can be integrally injection molded. Through the above design, the present disclosure can utilize the insulating member 321 to ensure the insulation performance between the auxiliary lead-out structure 320 and the coil frame 430 and the yoke iron plate 520 , and further improve the connection reliability and connection efficiency of the auxiliary lead-out structure 320 .

[0080] like Figure 6 As shown, in one embodiment of the present disclosure, the relay proposed in the present disclosure also includes a magnetic circuit part, which is partially arranged in the shell, and the magnetic circuit part includes a coil assembly, and the coil assembly includes a coil frame 430 and a coil 410 wound on the coil frame 430, and the coil 410 is connected to a coil lead-out structure 420, and the coil lead-out structure 420 is led out from the shell.

[0081] like Figure 6As shown, based on the design that the relay includes a magnetic circuit part and the coil 410 of the magnetic circuit part is connected to the coil lead-out structure 420, in one embodiment of the present disclosure, the coil lead-out structure 420 and the main static contact 310 can be respectively led out from the housing along the opposite sides of the first direction X, that is, the coil lead-out structure 420 is led out from the second housing 120 along the first direction X. Through the above design, the present disclosure can realize the lead-out of high and low voltage lead-out structures on different sides, and further on the opposite sides, thereby further improving the insulation distance between the two. On this basis, when the coil lead-out structure 420 is led out from the second housing 120, the auxiliary contact assembly can also be a functional component that is first assembled with the second housing 120, thereby further improving the convenience of assembly.

[0082] In an embodiment not shown in the figure of the present disclosure, the coil lead-out structure 420 can also be led out from the side wall 1113 of the first housing 110. Further, the coil lead-out structure 420 can be led out from the side wall 1113 on the same side as the auxiliary lead-out structure 320 along the second direction Y. Through the above design, the present disclosure can realize the installation of the relay in a horizontal manner, that is, the installation manner in which the end wall 1112 of the first housing 110 is perpendicular to the installation plane of the relay, thereby reducing the installation space of the relay in the height direction, which is conducive to the installation of the relay in a small space.

[0083] In addition, the magnetic circuit part also includes an iron core assembly, which is accommodated in the through hole of the coil frame 430, 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 410, a certain current flows through the coil 410, 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 310. When the coil 410 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 310.

Through the above design, the present invention assembles one of the coil lead-out structure 420 and the auxiliary lead-out structure 320 on the assembly plate 112. On the basis of realizing the lead-out of the high and low voltage lead-out structures on different sides, the high and low voltage lead-out structures can be assembled along different directions relative to the outer shell, thereby improving the structural rationality, reducing the difficulty of assembly, and being conducive to improving assembly efficiency.
