[0060] 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 and an auxiliary contact assembly.

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.

[0061] like Figure 1 and Figure 2As shown, in one embodiment of the present disclosure, the relay proposed in the present disclosure includes a housing 100, a main contact assembly, and an auxiliary contact assembly. Specifically, the main contact assembly is partially disposed in the housing 100, and the main contact assembly includes a main static contact 210, which is the high-voltage side lead-out structure of the relay, and the main static contact 210 is led out from one side of the housing 100 along the first direction X. The auxiliary contact assembly is partially disposed in the housing 100, and the auxiliary contact assembly includes an auxiliary lead-out structure 311, which is a part of the low-voltage side lead-out structure of the relay (for example, the low-voltage side lead-out structure may also include a coil lead-out structure), and the auxiliary lead-out structure 311 is led out from one side of the housing 100 along the second direction Y, the first direction X is perpendicular to the second direction Y, and the lead-out position of the auxiliary lead-out structure 311 on the housing 100 is located in the middle area of ​​the housing 100 in the first direction X, and the so-called "middle area" can be understood as the remaining area other than the two ends. Through the above structural design, the present disclosure can realize that the main static contact 210 and the auxiliary lead-out structure 311 of the relay are respectively led out from the housing 100 in two perpendicular directions, thereby being suitable for realizing horizontal installation of the relay, reducing the installation space required for the relay in the height direction, and facilitating the installation of the relay in a small space. Among them, the so-called "horizontal" means that when the installation surface of the external device used to install the relay is arranged in a direction perpendicular to the lead-out pin of the auxiliary lead-out structure 311, that is, when the installation surface of the external device is perpendicular to the second direction Y, then the first direction X is parallel to the installation surface of the external device. At this time, if the first direction X is used as the height direction of the relay, the relay can be regarded as being arranged on the external device in a lying posture.

[0062] In one embodiment of the present disclosure, the main contact assembly may further include an active contact sheet, and the main contact assembly includes two main static contacts 210, both ends of the active contact sheet are provided with active contacts, and the two main static contacts 210 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 the two active contact sheets are provided with active contacts, and the two main static contacts 210 are respectively arranged corresponding to the two ends of the two active contact sheets.

[0063] like Figures 3 to 7As shown, in one embodiment of the present disclosure, the relay proposed in the present disclosure also includes a magnetic circuit portion, and the magnetic circuit portion and the auxiliary contact assembly are arranged along the first direction X. Wherein, the magnetic circuit portion includes a coil assembly and a yoke assembly, the coil assembly includes a coil frame 410, and the yoke assembly includes a yoke plate 510, and the yoke plate 510 is located on the side of the coil frame 410 facing the auxiliary contact assembly in the first direction X. On this basis, the auxiliary lead-out structure 311 can be partially arranged between the coil frame 410 and the yoke plate 510. Through the above-mentioned structural design, the present disclosure can use the coil frame 410 and the yoke plate 510 to achieve the positioning of the auxiliary lead-out structure 311 in the first direction X.

[0064] like Figures 7 to 10 As shown, based on the structural design that the auxiliary lead-out structure 311 is partially disposed between the coil frame 410 and the yoke iron plate 510, in one embodiment of the present disclosure, a receiving groove 4121 may be disposed between the coil frame 410 and the yoke iron plate 510, and the auxiliary lead-out structure 311 is partially accommodated in the receiving groove 4121. Through the above structural design, the present disclosure can utilize the receiving groove 4121 to accommodate the portion of the auxiliary lead-out structure 311 disposed between the coil frame 410 and the yoke iron plate 510, thereby avoiding structural interference or squeezing of the auxiliary lead-out structure 311, and at the same time ensuring the assembly effect of the remaining positions of the coil frame 410 and the yoke iron plate 510.

[0065] like Figure 8 , Fig. 9 and Fig.11 As shown, based on the structural design that the auxiliary lead-out structure 311 is partially disposed between the coil frame 410 and the yoke iron plate 510, in one embodiment of the present disclosure, the portion of the auxiliary lead-out structure 311 located between the coil frame 410 and the yoke iron plate 510 can be provided with a first positioning structure, and correspondingly, a second positioning structure can be provided on the surface of the side of the yoke iron plate 510 facing the coil frame 410 at a position corresponding to the first positioning structure, and the second positioning structure is positioned and matched with the first positioning structure. Through the above structural design, the present disclosure can limit the relative position of the yoke iron plate 510 and the auxiliary lead-out structure 311 in the second direction Y and the third direction Z by using the positioning and matching of the first positioning structure and the second positioning structure.

[0066] like Figure 8 , Fig. 9 and Fig.11As shown, based on the structural design of the first positioning structure and the second positioning structure, in one embodiment of the present disclosure, the first positioning structure can be a positioning hole 3132, and the second positioning structure can be a positioning protrusion 511, and accordingly, the positioning protrusion 511 is inserted into the positioning hole 3132 to achieve positioning cooperation. In some embodiments, the first positioning structure can also be a positioning protrusion 511, and the second positioning structure can also be a positioning hole 3132, or the positioning hole 3132 can also be replaced by a positioning groove, which is not limited to this embodiment.

[0067] like Fig.11 As shown, based on the structural design of the above-mentioned first positioning structure and the second positioning structure, in one embodiment of the present disclosure, the auxiliary lead-out structure 311 can be provided with at least two first positioning structures arranged at intervals, such as but not limited to the two first positioning structures arranged at intervals along the third direction Z shown in the accompanying drawings. Furthermore, the yoke iron plate 510 can be provided with at least two second positioning structures. Accordingly, at least two first positioning structures are arranged one-to-one with at least two second positioning structures. On this basis, at least one positioning protrusion 511 is a cylindrical protrusion, and the positioning hole 3132 matched therewith is a circular hole. And, at least another positioning protrusion 511 is an elliptical protrusion, and the positioning hole 3132 matched therewith is an elliptical hole. Through the above-mentioned structural design, the present disclosure can further enhance the positioning effect of the auxiliary lead-out structure 311, and at the same time can avoid the difficulty of assembling the positioning protrusion 511 and the positioning hole 3132 due to dimensional tolerance.

[0068] like Figures 8 to 10 As shown, based on the structural design of the first positioning structure and the second positioning structure, in one embodiment of the present disclosure, taking the side surface of the coil frame 410 facing the yoke iron plate 510 as an example, the auxiliary lead-out structure 311 is partially accommodated in the accommodating groove 4121. On this basis, the side surface of the coil frame 410 facing the yoke iron plate 510 can also be provided with an assembly groove 4122, which is connected to the accommodating groove 4121, and the part of the auxiliary lead-out structure 311 located between the coil frame 410 and the yoke iron plate 510 is connected with an assembly portion 3131, which can be accommodated in the assembly groove 4122. At this time, the first positioning structure can be provided on the assembly portion 3131.

[0069] like Figures 8 to 10As shown, based on the structural design that the coil frame 410 is provided with a receiving groove 4121 and an assembly groove 4122, in one embodiment of the present disclosure, the receiving groove 4121 opens at one side edge of the coil frame 410 in the second direction Y, so that the auxiliary lead-out structure 311 can extend from the receiving groove 4121. On this basis, the assembly groove 4122 can be connected to the opposite side of the receiving groove 4121 in the second direction Y, and the assembly portion 3131 and the portion of the auxiliary lead-out structure 311 extending from the receiving groove 4121 are respectively located on opposite sides in the second direction Y. Through the above structural design, when the portion of the auxiliary lead-out structure 311 extending out is subjected to an external force along the second direction Y (for example, when the lead-out pin of the auxiliary lead-out structure 311 is subjected to force when plugging and unplugging with an external device), the external force can directly act on the positioning position of the assembly portion 3131 and the yoke iron plate 510, that is, between the first positioning structure and the second positioning structure, thereby fully exerting the positioning function of the above mechanism and ensuring the structural stability and connection effectiveness of the auxiliary lead-out structure 311.

[0070] like Figures 9 to 11 As shown, based on the structural design that the coil frame 410 is provided with a receiving groove 4121 and an assembly groove 4122, in one embodiment of the present disclosure, along the first direction X, the thickness of the assembly portion 3131 can be less than the thickness of the portion of the auxiliary lead-out structure 311 received in the receiving groove 4121, and the groove depth of the assembly groove 4122 can be less than the groove depth of the receiving groove 4121. Accordingly, the bottom surface of the groove structure formed by the receiving groove 4121 and the assembly groove 4122 is a step-like structure, which can not only avoid excessive occupation of the space of the coil frame 410, but also facilitate the step-like structure to realize the positioning of the auxiliary lead-out structure 311 in the second direction Y.

[0071] like Figure 4 , Figure 5 , Figure 8 and Fig.10As shown, based on the structural design that the auxiliary lead-out structure 311 is partially arranged between the coil frame 410 and the yoke iron plate 510, in one embodiment of the present disclosure, a part of the auxiliary lead-out structure 311 is provided with an insulating member 313, and the auxiliary lead-out structure 311 has a lead-out end 3111 and a connecting end 3112 that extend out of the insulating member 313 respectively, and the lead-out end 3111 leads out of the housing 100 along the second direction Y. The auxiliary contact assembly may also include an auxiliary static contact lead-out member 312 and an auxiliary moving contact piece. The connecting end 3112 is connected to one end of the auxiliary static contact lead-out member 312, and the other end of the auxiliary static contact lead-out member 312 is used as an auxiliary static contact lead-out end to contact or separate with the two ends of the auxiliary moving contact piece. On this basis, the insulating member 313 is at least partially arranged between the coil frame 410 and the yoke iron plate 510. Through the above structural design, the present disclosure can utilize the insulating member 313 to ensure the insulation performance between the auxiliary lead-out structure 311 and the yoke plate 510 and the coil frame 410 , while facilitating the assembly of the auxiliary lead-out structure 311 between the yoke plate 510 and the coil frame 410 .

[0072] In one embodiment of the present disclosure, the auxiliary contact assembly includes two auxiliary static contact lead-out pieces 312, two auxiliary lead-out structures 311 and an auxiliary moving contact piece. Each end of the two auxiliary static contact lead-out pieces 312 is used as an auxiliary static contact for contacting or separating with the two ends of the auxiliary moving contact piece. Each other end of the two auxiliary static contact lead-out pieces 312 is respectively connected to each end of the two auxiliary lead-out structures 311. Each other end of the two auxiliary lead-out structures 311 is used as a lead-out portion and is led out of the housing 100. The so-called lead-out portion refers to the portion of the auxiliary lead-out structure 311 that is led out of the housing 100. On this basis, the lead-out portions (i.e., the lead-out end portions 3111) of the two auxiliary lead-out structures 311 can be arranged at intervals along the third direction Z, and the third direction Z is perpendicular to the first direction X and perpendicular to the second direction Y.

[0073] Based on the design that the auxiliary contact assembly includes two auxiliary static contact lead-out pieces 312 and two auxiliary lead-out structures 311, 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 312 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 312 and two auxiliary lead-out structures 311, and the two auxiliary lead-out structures 311 are connected to the auxiliary moving contact piece and the auxiliary static contact lead-out piece 312, respectively.

[0074] Based on the structural design that the auxiliary contact assembly includes the auxiliary lead-out structure 311 and the insulating member 313 , in one embodiment of the present disclosure, the auxiliary lead-out structure 311 and the insulating member 313 can be integrally injection molded.

[0075] Based on the structural design that the auxiliary contact assembly includes an auxiliary lead-out structure 311, an auxiliary static contact lead-out piece 312 and an insulating piece 313, in one embodiment of the present disclosure, a connecting end 3112 of the auxiliary lead-out structure 311 and one end of the auxiliary static contact lead-out piece 312 can be connected via soldering.

[0076] like Figure 6 , Figure 7 and Fig.10 As shown, based on the structural design that the auxiliary lead-out structure 311 is partially disposed between the coil frame 410 and the yoke iron plate 510, in one embodiment of the present disclosure, the coil frame 410 includes a winding column 411, a first baffle 412 and a second baffle 413, the winding column 411 extends along the first direction X and is provided for the coil 420 to be wound, the first baffle 412 and the second baffle 413 are respectively disposed at the two ends of the winding column 411 in the first direction X, and the first baffle 412 is closer to the auxiliary contact assembly than the second baffle 413. On this basis, the yoke iron plate 510 is disposed on a side surface of the first baffle 412 facing away from the second baffle 413, and the auxiliary lead-out structure 311 is partially disposed between the first baffle 412 and the yoke iron plate 510. In other words, the above-mentioned accommodating groove 4121 and the assembly groove 4122 can be opened on a side surface of the first baffle 412 facing the yoke iron plate 510.

[0077] like Figure 3 and Figure 4 As shown, based on the structural design that the auxiliary lead-out structure 311 is partially disposed between the coil frame 410 and the yoke plate 510, in one embodiment of the present disclosure, the yoke assembly further includes a U-shaped yoke 520, and the U-shaped yoke 520 includes two side portions 521 and a connecting portion 522, the two side portions 521 are arranged at intervals and are respectively located on both sides of the coil assembly in the third direction Z, the third direction Z is perpendicular to the first direction X and perpendicular to the second direction Y, and the two ends of the connecting portion 522 in the third direction Z are respectively connected to the ends of the two side portions 521 away from the auxiliary contact assembly in the first direction X. On this basis, the two ends of the yoke plate 510 in the third direction Z are respectively connected to the ends of the two side portions 521 close to the auxiliary contact assembly in the first direction X, and the auxiliary lead-out structure 311 extends from the yoke plate 510 and the coil frame 410 on one side in the second direction Y.

[0078] like Figure 1 and Figure 2As shown, in one embodiment of the present disclosure, the housing 100 may have a first wall 101 and a second wall 102, wherein the first wall 101 is perpendicular to the first direction X, and the second wall 102 is perpendicular to the second direction Y. On this basis, the main static contact 210 may be led out from the first wall 101, and the auxiliary lead-out structure 311 may be led out from the second wall 102. In other words, the lead-out direction of the main static contact 210 may be perpendicular to the first wall 101, and the lead-out direction of the auxiliary lead-out structure 311 may be perpendicular to the second wall 102. In some embodiments, when the housing 100 adopts other structural forms (for example, the cross-section of the housing 100 is circular or elliptical), the housing 100 also does not have a wall surface perpendicular to the lead-out direction of the above-mentioned lead-out structure, which is not limited to this embodiment.

[0079] 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.

[0080] In one embodiment of the present disclosure, the lead-out portion of the main static contact 210 may extend along the first direction X, and the so-called lead-out portion refers to a portion of the main static contact 210 that is led out of the housing 100 .

[0081] In one embodiment of the present disclosure, the lead-out portion of the auxiliary lead-out structure 311 may extend along the second direction Y, and the so-called lead-out portion refers to the portion of the auxiliary lead-out structure 311 that is led out of the housing 100. Through the above design, the present disclosure can make the lead-out portion of the auxiliary lead-out structure 311 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 that is perpendicular to the second direction Y in a plug-in manner.

[0082] See also Fig.12 and Fig.13 , Fig.12 : 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.13 Representatively shown in Fig.12 The schematic diagram of the three-dimensional exploded view of the relay is shown, in which the first housing and the second housing are separated along the first direction.

[0083] like Fig.12 and Fig.13As 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, and the main static contact 211 is led out by 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 of the first shell 110, that is, 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 of the first shell 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. On this basis, the auxiliary lead-out structure 311 can 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 relatively independent of the body 111 to assemble with the auxiliary lead-out structure 311, 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 311 and the housing 100, which is conducive to reducing the difficulty of assembly and improving the assembly efficiency. Furthermore, since the lead-out direction (for example, the second direction Y) of the auxiliary lead-out structure 311 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 lead-out direction is different from the installation direction, and will not change the overall structure of the first shell 110, thereby not affecting the glue-dispensing insulation of the main static contact 210.

[0084] 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).

[0085] 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.

[0086] In summary, a relay proposed in the present disclosure includes a housing 100, a main contact assembly and an auxiliary contact assembly; the main contact assembly is arranged in the housing 100, and includes two main static contacts 210 and an active contact piece, and the main static contact 210 is led out from one side of the housing 100 along a first direction X; the auxiliary contact assembly is arranged in the housing 100, and includes an auxiliary lead-out structure 311, and the auxiliary lead-out structure 311 is led out from one side of the housing 100 along a second direction Y, and the first direction X is perpendicular to the second direction Y. Through the above structural design, the present disclosure can realize that the main static contact 210 and the auxiliary lead-out structure 311 of the relay are respectively led out from the housing 100 in two perpendicular directions, thereby being suitable for realizing horizontal installation of the relay, reducing the installation space required for the relay in the height direction, and facilitating the installation of the relay in a small space.
